-## The general stuff
+## Allgemeines
-The car is a 1991 VW T4, with a 2.0l **Benzin** (petrol) engine.
-That means roughly 80 PS. No mountains and offroading for you in there.
+Das Auto ist ein **VW T4** aus dem Jahr **1990** mit einem **2,0 L Benzinmotor** und etwa **80 PS**.
+Keine Berge und kein Offroad – das ist ein gemütlicher Begleiter, kein Abenteuermobil.

-The Car uses about 10-12l/100km, when never going beyond 90 km/h.
-Otherwise it uses about 12-15l/100km.
+Der Verbrauch liegt bei etwa **10–12 L / 100 km**, wenn du unter 90 km/h bleibst.
+Darüber hinaus sind **12–15 L / 100 km** realistischer.
-The tank is 85l, so you can go about 750km on one tank.
-The tank needle is broken, so you have to use the trip meter to know how much fuel is left.
-Always refill completely, otherwise you will have no clue about your range.
+Der Tank fasst **75 L**, was einer Reichweite von rund **750 km** pro Tankfüllung entspricht.
+Die Tankanzeige ist **defekt**, daher musst du den Kilometerzähler nutzen, um den Füllstand zu verfolgen.

-The car is a manual, so you need to know how to drive stick.
-There is no Servolenkung (power steering), so it is a bit harder to steer.
-There is a trailer hitch for up to 1000 kg total. This means a standard 750kg trailer is fine, a complete rv trailer is not.
-The car is a 4 seater.
+Das Auto hat ein **manuelles Getriebe**, du musst also **Schaltgetriebe fahren können**.
+Es gibt **keine Servolenkung**, das Lenken ist also etwas schwerer.
+Eine **Anhängerkupplung** ist vorhanden (max. **1.000 kg Gesamtgewicht**) – also kein Problem für kleine Anhänger bis 750 kg, aber **kein Wohnwagen**.
+Das Auto hat **vier Sitzplätze**.
-The car is insured for everyone over 25 years old, who has a valid drivers license.
-It has Teilkasko, which means that you are insured for everything, except for damage to the car itself.

-## Electricity
+## Strom
-The van has it's own solar system, meaning that in summer you can usually go off-grid.
-There is some 12v plugs and several USB and USB-C plugs. No 230v plugs. If you need 230v, that is only possible with grid connection (Landstromanschluss). All necessary cables are on board.
-Please plan accordingly.
+Der Bus hat eine eigene **Solaranlage**, die im Sommer meist **autarkes Stehen** ermöglicht.
+Es gibt mehrere **12 V-Anschlüsse**, sowie **USB- und USB-C-Buchsen**, aber **keine 230 V-Steckdosen**.
+Wenn du 230 V benötigst, musst du über den **Landstromanschluss** ans Netz gehen.
+Alle nötigen Kabel sind an Bord – plane das bei der Reise mit ein.
-The solar system functions automatically and has an automatic shut-off, so you can't drain the battery. In case you wanna monitor the battery, you can use the [Victron App](https://www.victronenergy.com/live/victronconnect:start) to connect to the solar system via Bluetooth. Ask me for the pin.
-For the Analogue people, there is a battery monitor in the car, that shows the current battery voltage. It is right next to the driver seat and can read the front starter battery and the support back battery.
-Anything below 11.5V is considered empty and you should start the car to recharge the battery. There is a battery booster, which will charge both batteries while driving.
+Das Solarsystem läuft automatisch und schützt vor Tiefentladung.
+Wenn du den Ladezustand sehen möchtest, verbinde dich mit der [Victron App](https://www.victronenergy.com/live/victronconnect:start) via Bluetooth – frage mich nach der PIN.
+Für die Analogen unter euch gibt es einen **Batteriemonitor** neben dem Fahrersitz, der die Spannung von Starter- und Bordbatterie anzeigt.
+Alles unter **11,5 V** bedeutet: Batterie leer → Motor starten, um zu laden.
+Ein **Batteriebooster** lädt beide Batterien während der Fahrt.
+Im Notfall gibt es eine **Powerbank**, mit der sich das Auto überbrücken lässt.
-For increased solar capacity, take out the folded panels, plug their cable into the adapter at the rear under the exhaust pipe and place the panels in the sun. The solar system will automatically use the additional power.
-{: .notice--info}
+{% alert(note=true) %}
+Für mehr Solarkapazität kannst du die **faltbaren Solarpaneele** anschließen:
+Stecke das Kabel in den Anschluss hinten unter dem Auspuff und lege die Paneele in die Sonne.

-The kitchen is equipped with a 2 flame gas stove and a sink with running water.
-The water is stored in a 15l tank, which is filled from the outside. Using it awarely, it can last for about 3 days (2 people).
+Die Küche hat einen **zweiflammigen Gasherd** und ein **Spülbecken mit fließendem Wasser**.
+Das Wasser kommt aus einem **15 L-Tank**, der außen befüllt wird.
+Bei sparsamer Nutzung reicht das für etwa **drei Tage** zu zweit.
-Gas is standard 5kg grey gas bottles, which can be exchanged at any gas station. There is a bottle in the car, which is usually enough for more than a month of cooking. If you run out, you can exchange it at any gas station.

-While learning about 3D Printing, I was most intrigued by the possibility to modify and repair existing products. While there is an amazing community with lots of good and free models around, naturally I came to a point where I did not find what I was looking for readily designed. I realized this is an essential skill for effectively operating not just 3D Printers, but any productive machine really.
+Beim Erlernen des 3D-Drucks hat mich vor allem die Möglichkeit fasziniert, bestehende Produkte zu verändern oder zu reparieren.
+Auch wenn es eine großartige Community mit vielen guten und kostenlosen Modellen gibt, bin ich schnell an den Punkt gekommen, an dem ich nicht fand, was ich suchte.
+Mir wurde klar, dass dies eine wesentliche Fähigkeit ist, um nicht nur 3D-Drucker, sondern grundsätzlich jede Art von Produktionsmaschine sinnvoll zu nutzen.
-Since youtube was the place I was learning all about 3D Printing, and all the people that I looked up to there were using Fusion 360 as their CAD Program that’s what I got into.
-In hindsight, that was a pretty good choice and I am in love with the abilities parametric design gives me.
-Below you will find some of my designs.
-The process is something that I enjoy a lot and wish to dive into deeper.
+Da ich alles über 3D-Druck auf YouTube gelernt habe und dort fast alle mit **Fusion 360** arbeiteten, habe ich mich ebenfalls dafür entschieden.
+Rückblickend war das eine sehr gute Wahl – ich habe mich in die Möglichkeiten des **parametrischen Designs** verliebt.
+Unten findest du einige meiner Entwürfe.
+Der Prozess selbst macht mir unglaublich viel Spaß und ich möchte ihn noch weiter vertiefen.
-By trial and error, I already learned a lot about designing specifically for 3D Printing, but I often feel that there are many aesthetic considerations in design that I am not familiar with.
-I want to broaden my general ability to design physical objects, which is something I hope to gain during my master’s.
+Durch Ausprobieren habe ich bereits viel darüber gelernt, wie man speziell für den 3D-Druck konstruiert.
+Trotzdem habe ich oft das Gefühl, dass mir ein tieferes Verständnis für **ästhetische Gestaltung** fehlt.
+Ich möchte meine generelle Fähigkeit erweitern, physische Objekte zu entwerfen – etwas, das ich mir im Masterstudium erhoffe.

-In the last few years I have played around with a few smartphone cameras and was always quite sad, that my scans were never quite accurate enough to do cool stuff with them.
-I could not really afford real 3D scanner and had already started cobbling together a raspberry Pi camera with a cheap TOF sensor, which is a simple, but not quite as good replacement for a laser or a lidar sensor, but then Apple came out with the first phones with accessible Lidar sensor.
-Recently, through work at the university I got access to a device with a lidar sensor and started having fun with it.
-See some examples here:
+In den letzten Jahren habe ich mit verschiedenen Smartphone-Kameras experimentiert – leider waren meine Scans meist nicht präzise genug, um wirklich etwas damit anzufangen.
+Ein professioneller 3D-Scanner war zu teuer, also bastelte ich mir eine Kombination aus einer **Raspberry-Pi-Kamera** und einem günstigen **TOF-Sensor**.
+Das Setup ist simpel, aber bei weitem nicht so genau wie Laser- oder LiDAR-Sensoren. Dann brachte Apple die ersten Geräte mit **zugänglichem LiDAR** heraus.
-
+Durch meine Arbeit an der Universität hatte ich schließlich Zugriff auf ein Gerät mit LiDAR und begann, damit zu experimentieren.
+Ein paar Beispiele siehst du hier:
-
+
-This last one was scanned with just my smartphone camera. You can see that the quality is notably worse, but considering is was created with just a single, run-of-the-mill smartphone sensor, I think it is still pretty impressive and will certainly do something towards democratizing such technologies and abilities.
+
+
+Der letzte Scan hier wurde nur mit einer **Smartphone-Kamera** erstellt.
+Man erkennt deutlich, dass die Qualität geringer ist, aber angesichts der einfachen Technik finde ich das Ergebnis beeindruckend –
+und es zeigt, wie sehr solche Technologien gerade **demokratisiert** werden.
-## Perspective
+## Perspektive
-What this section is supposed to deliver is the message that I am currently not where I want to be navigating the vast possibilities of CAD. I feel confident enough to approach small repairs around the flat with a new perspective, but I still lack technical expertise when approaching a collection composite parts, having to function together. I still have lots of projects halfdone or half-thought and one major reason is that there is no real critical exchange within my field of study.
+Was dieser Abschnitt zeigen soll: Ich bin beim Thema **CAD** noch nicht da, wo ich gerne wäre.
+Ich fühle mich sicher genug, um kleine Reparaturen im Alltag anzugehen,
+aber beim **Konstruieren komplexer Bauteilgruppen**, die zusammen funktionieren müssen, fehlt mir noch technisches Know-how.
+Viele meiner Projekte sind halbfertig – einer der Hauptgründe ist der **Mangel an fachlichem Austausch** in meinem Umfeld.
-I want more than designing figurines or wearables.
-I want to incorporate 3D printing as a method to extend the abilities of other tools, have mechanical and electrical purposes, be foodsafe and engaging.
-I fell in love with the idea of designing a toy system, inspired by [Makeways on Kickstarter](https://www.kickstarter.com/projects/makeway/makeway-create-intricate-courses-watch-your-marbles-soar), I have already started adding my own parts to their set.
+Ich möchte mehr als nur Figuren oder Wearables gestalten.
+Ich möchte den **3D-Druck als Werkzeugerweiterung** nutzen –
+für mechanische oder elektrische Anwendungen, lebensmittelechte Objekte, oder einfach Dinge, die begeistern.
+Ich liebe die Idee, ein **Baukastensystem** zu entwickeln.
+Inspiriert von [Makeways auf Kickstarter](https://www.kickstarter.com/projects/makeway/makeway-create-intricate-courses-watch-your-marbles-soar) habe ich bereits angefangen, eigene Teile zu entwerfen.
-I dream of my very own 3D printed coffeecup, one that is both foodsafe and dishwasher-surviving. For that, I would have to do quite a bit of material research, but that just makes the idea so much more appealing.
-I would love finding a material composition incorporating waste to stop relying on plastics, or at least on fossile plastics.
-Once in Berlin, I would want to talk to the people at [Kaffeform](https://www.kaffeeform.com/en/) producing largely compostable Coffee Cups incorporating a significant amount of old ground espresso, albeit using injection molding for their process.
-The industry selling composite filaments is much more conservative with the percentage of non-plastic additives, because with a nozzle extrusion process there is much more to go wrong.
-Still, I would love to explore that avenue further and think there is a lot to be gained from looking at pellet printers.
+Ein Traum von mir ist eine **eigene 3D-gedruckte Kaffeetasse**, die sowohl **spülmaschinenfest als auch lebensmittelecht** ist.
+Dafür müsste ich viel Materialforschung betreiben – aber genau das macht es spannend.
+Ich möchte ein Material finden, das **Abfälle** einbezieht, um weniger von **fossilen Kunststoffen** abhängig zu sein.
+In Berlin möchte ich mich mit den Leuten von [Kaffeform](https://www.kaffeeform.com/de/) austauschen, die **kompostierbare Becher** aus gebrauchten Espressoresten herstellen (wenn auch per Spritzgussverfahren).
-I also credit huge parts of my exploration process into local recycling to the awesome people at [Precious Plastic](https://preciousplastic.com), who I will join over the summer to learn more about their system.
+Die Hersteller von **Komposit-Filamenten** sind bei der Beimischung nicht-plastischer Stoffe sehr vorsichtig,
+weil der **Extrusionsprozess** durch Düsen leicht fehleranfällig ist.
+Trotzdem glaube ich, dass gerade in diesem Bereich noch viel Potenzial steckt – besonders mit **Pelletdruckern**.
-I find it hard to write anything about CAD without connecting it directly to a manufacturing process.
-And I believe that's a good thing. Always tying a design process to its realization, grounds the process and attaches to it some immediacy.
+Große Teile meiner Auseinandersetzung mit **lokalem Recycling** verdanke ich den großartigen Leuten von [Precious Plastic](https://preciousplastic.com), deren Open-Source-Designs mich sehr inspiriert haben.
+Ich finde es schwer, über CAD zu schreiben, ohne gleichzeitig über den **Herstellungsprozess** zu sprechen –
+und ich halte das für etwas Gutes.
+Design und Umsetzung gehören für mich zusammen.
-For me to become more confident in this process, I am still missing more expertise in organic shapes, so I would be happy to dig more into Blender, an awesome tool that in my mind is far too powerful to dive into it with just youtube lessons.
+Um noch sicherer zu werden, möchte ich mich stärker auf **organische Formen** konzentrieren.
+Deshalb will ich tiefer in **Blender** einsteigen – ein großartiges Tool, das viel zu mächtig ist, um es nur über YouTube zu lernen.

-## BEACON: Decentralizing the Energy Grid in inaccessible and remote regions
-Access to Electricity is a basic human right. At first, that may seem over the top, but if one stops to think what all the little tasks that electricity can indirectly handle for us (lightning, laundry, cooking, freezing, heating, entertaining…) would consume in time and effort if we had to perform them manually, this idea becomes very clear. There are globally around 1 billion people without tier 2 access to electricity.
+## BEACON: Dezentralisierung des Stromnetzes in unzugänglichen und abgelegenen Regionen
-[SDGS Goal 7](https://sdgs.un.org/goals/goal7)
+Zugang zu Elektrizität ist ein grundlegendes Menschenrecht. Das mag zunächst übertrieben klingen, doch wenn man bedenkt, wie viele kleine Aufgaben der Strom uns indirekt abnimmt – Licht, Wäsche, Kochen, Kühlen, Heizen, Unterhaltung – wird schnell klar, wie viel Zeit und Aufwand ohne Elektrizität nötig wäre. Weltweit leben etwa **eine Milliarde Menschen** ohne Zugang zu Strom auf dem sogenannten Tier-2-Level.
-
+[SDGS Ziel 7](https://sdgs.un.org/goals/goal7)
-People only know the intensity of labor that goes into everything when there is no electricity. And it is not even only about convenience, electricity is an enormous lifesaver in any number of scenarios, think just of hospitals or mobile phone networks that would be rendered completely useless without it. So we can easily agree on a need, a demand for electricity globally, for every person. But what about the supply? Why is there 1 billion undersupplied?
-The Answer: missing profitability. It would be a charity project to supply every last person on earth, not a profitable one. And while charitable projects are noble and should be pursued, the reality within capitalism shows that this is not the way it is going to happen.
-But what if we could come up with technology, or rather, a communal structure, that enables us to supply profitably, and still adapt to both, the difficult external factors (weather issues, remoteness, altitude, etc.) and the smaller purses of the undersupplied?
+
-### Location
+Menschen erkennen erst dann, wie viel Arbeit in alltäglichen Dingen steckt, wenn sie keinen Strom haben. Doch es geht dabei nicht nur um Bequemlichkeit – Elektrizität rettet Leben: Krankenhäuser, Telekommunikation, Kühlung von Medikamenten – all das hängt davon ab.
+Warum also sind immer noch so viele Menschen unterversorgt?
+**Die Antwort: fehlende Rentabilität.** Es wäre ein wohltätiges, aber kein profitables Projekt, jede Person auf der Welt zu versorgen. Doch was, wenn wir eine Struktur finden könnten, die **wirtschaftlich tragfähig** ist und sich gleichzeitig an schwierige Bedingungen (Wetter, Abgeschiedenheit, Höhenlage) sowie an kleinere Einkommen anpassen kann?
-Towards the end of 2018, I spent 4 months in northern India, on a research project with the IIT Kharagpur.
-The goal was to work on one of the 17 UN-defined sustainable development goals – electricity.
+### Standort
-Worldwide, an estimated 1 billion people have no or insubstantial access to the grid.
-Some of them live here, in the Key Monastery in the Spiti Valley at around 3500 meters altitude.
+Ende 2018 verbrachte ich vier Monate im Norden Indiens – im Rahmen eines Forschungsprojekts mit dem **IIT Kharagpur**.
+Das Ziel: an einem der 17 von der UN definierten nachhaltigen Entwicklungsziele zu arbeiten – Elektrizität.
-
+Weltweit haben schätzungsweise **eine Milliarde Menschen** keinen oder nur unzureichenden Zugang zum Stromnetz.
+Einige davon leben hier – im **Key-Kloster** im Spiti-Tal, auf etwa 3500 Metern Höhe.
-
+
-
+
-This is Tashi Gang, a village close to the Monastery. It houses around 50 people and only has road access during 3-4 months in the summer. For the rest of the time, the people rely on first aid services by helicopter, which can only be called with a working cell phone tower.
+
-
+Das ist **Tashi Gang**, ein Dorf nahe des Klosters. Es beherbergt rund 50 Menschen und ist nur drei bis vier Monate im Sommer über eine Straße erreichbar. Den Rest des Jahres sind die Bewohner auf Hubschrauber-Erste-Hilfe angewiesen – erreichbar nur über einen funktionierenden Mobilfunkturm.
-## The Project
+
-In an environment reliant on hydro-energy and solar (diesel transport is unreliable due to snowed-in mountain roads), over 6 months of snowy winter, frequent snowstorms, and temperatures of up to -35°C, securing the grid is hard.
+## Das Projekt
-Our way to tackle the issue was to reject the in the western society very established notion of electricity as a homogenous product with centralized production and instead researched the possibilities of a predictive, self-correcting, and decentral grid.
+In einer Umgebung, die auf Wasser- und Sonnenenergie angewiesen ist, mit über sechs Monaten Schnee, häufigen Schneestürmen und Temperaturen bis zu –35 °C, ist die Netzsicherung schwierig.
-By prioritizing energy usage cases, instead of a full blackout during a storm, essential functions like radio towers and hospitals could be partially powered and maybe stay functioning. The binarity of either having electricity or not would be replaced by assigned quantities and timeslots, in a collective effort to be mindful and distribute the electricity necessity-based.
-The ultimate vision was a live predictive electricity market, where people could even earn money by selling their allotted, but not needed electricity.
-To gauge feasibility, I conducted several psychological acceptance studies and collected data on local electricity demands.
-I simulated a typical day of electricity demand in the Key monastery and the surrounding villages and mapped out the potential to install cost-efficient smart microgrid controllers enabling such an accurate and predictive behavior.
-The smart grid operator boxes available here in Germany cost several hundred, with installation several thousand Euros, not a feasible solution for the Indian population. Instead, we wanted to use Raspberry Pi's, which are interconnected through ethernet cables or local mesh networking.
+Unser Ansatz war es, die im Westen etablierte Vorstellung von Elektrizität als homogenes, zentral erzeugtes Produkt zu hinterfragen und stattdessen die Möglichkeiten eines **prädiktiven, sich selbst korrigierenden und dezentralen Netzes** zu erforschen.
-## Research
+Anstatt bei einem Sturm einen kompletten Blackout zu riskieren, könnten bei einer Priorisierung der Energieverwendung wichtige Funktionen – etwa Radiotürme oder Krankenhäuser – teilweise weiterbetrieben werden. Die Binarität von Strom / kein Strom würde durch ein System von **Zuteilungen nach Bedarf und Zeitfenstern** ersetzt.
+Langfristig war die Vision ein **lokaler, prädiktiver Strommarkt**, bei dem Menschen überschüssige Energie verkaufen können.
-
+Zur Machbarkeitsprüfung führte ich psychologische Akzeptanzstudien durch und sammelte Daten zum lokalen Stromverbrauch. Anschließend simulierte ich einen typischen Strombedarfstag im Key-Kloster und in den umliegenden Dörfern und entwickelte Konzepte für kostengünstige **Smart-Microgrid-Controller**.
-## Data Collection
+Die hier in Deutschland verfügbaren Netzsteuerboxen kosten mehrere Hundert bis Tausend Euro – keine realistische Lösung für die Bevölkerung vor Ort. Stattdessen planten wir **Raspberry Pi-basierte Systeme**, vernetzt über Ethernet oder lokale Mesh-Netze.
-Building a questionnaire and visiting public schools during their English Classes, I had the chance to speak to a range of teenagers, answering questions about the state of electricity in their homes, generating more data than I could have accomplished running from door to door without any skills speaking local dialects. The questionnaire was as scientific as I could make it in such a situation and geared towards finding the type and number of electric devices in the homes and estimating typical usage scenarios.
+## Forschung
-With a total of 145 participants from more than 6 different schools and roughly 4 different districts, all located in the Indian part of the Himalayas, the findings are as follows:
+
-The participants range from 11 to 53 years, with an average of 17 years.
-The average household has 6 members with an average of 5 smart devices. Only 2 percent of the Households had not a single smart device, but at the same time, only 42 percent had direct or indirect access to a laptop or computer. So the main body of smart devices consists of smartphones with a negligible portion of tablets.
-The average total amount of electrical devices is around 11 electrical appliances per house.
+## Datenerhebung
-**Subjective** Quality Rating on a scale of 1 to 10:
-> Average quality in summer: 7.1
-> Average quality in monsoon: 5.6
-> Average quality in autumn: 7.1
-> Average quality in winter: 4.0
+Durch den Besuch öffentlicher Schulen im Englischunterricht konnte ich mit Jugendlichen über den Stromzustand in ihren Haushalten sprechen und umfangreiche Daten erheben. Insgesamt nahmen **145 Teilnehmer aus über sechs Schulen** in etwa **vier Distrikten** teil – alle im indischen Himalaya.
-So, as you would expect, during winter, but also when it rains, the felt quality drops by more than 30 percent on average.
-As for the daily supply time, the average sits at 15.1 hours out of 24, meaning the people have electricity only for 62.9 percent of the time, some, as for example the people in Diskit only have a sad 4 hours of daily access. On top of that, this estimation does not account for the snowfalls in Spiti for example, where it is not uncommon to experience 3 consecutive days of powercut or more.
-As the Power Meter is supplied by the government, a solid 82 percent of the houses have a working power meter, if one assumes that the 13 percent who did not know whether they have a power meter, do have one, we can say that around 95% of the houses have a power meter.
+Der Altersdurchschnitt lag bei 17 Jahren. Durchschnittlich leben 6 Personen pro Haushalt mit etwa 5 Smart-Geräten. Nur 2 % der Haushalte hatten gar keine, 42 % verfügten über Computer oder Laptops.
-Another goal of the studies was to find out what would incline people to be caring and sharing with the available electricity, something rather unimaginable here in Germany.
+> Durchschnittliche Stromqualität (1 – 10):
+> Sommer: 7,1 Monsun: 5,6 Herbst: 7,1 Winter: 4,0
-In general, the uninformed openness to delaying usage of electricity on a scale of 1-10 was around 5.5, with the additional information that a smart delay would cause an overall price reduction, the acceptance went up to 6.9, a good 14%. This implies that people would be a lot more inclined to give up conveniences if the benefits have a direct impact on them.
+Im Winter oder bei Regen sinkt die Qualität also deutlich – um über 30 %.
+Im Durchschnitt haben Haushalte **15,1 Stunden Strom pro Tag** (≈ 63 %). Einige Regionen, wie Diskit, nur rund 4 Stunden.
-## Simulation
+Etwa 95 % der Haushalte besitzen funktionierende Stromzähler.
-After collecting all the estimated electric appliances of the local population, I simulated the use of 200 Solar Panels with 300Wp each, once for simultaneous electricity use, and once for mitigated electricity peaks through smart optimization and electricity usage delay.
-
-
+Ein weiteres Ziel war herauszufinden, **was Menschen dazu bewegt, Strom zu teilen oder zu verschieben**.
+Ohne zusätzliche Information lag die Bereitschaft zur Verzögerung des Verbrauchs bei 5,5 / 10 – mit Aussicht auf Kostenvorteile stieg sie auf 6,9.
-Although solar is definitely not the optimal choice here and generates lots of issues with energy storage and battery charging at negative degrees, we figured that this was the way to go for the project.
-And as you can see, optimizing peak usage can improve solar from generating only one-fifth of the demand in winter to about half the demand in winter. Keeping in mind here, that the added solar farm was only intended to supply additional energy and not replace existing solutions, such a "small" farm would be a real lifesaver there and optimize the limited space in extremely mountainous terrain.
+## Simulation
-## Closing words
+Basierend auf den Daten simulierte ich den Einsatz von **200 Solarmodulen à 300 Wp**, einmal mit und einmal ohne intelligente Laststeuerung.
-There are to sides which the problems can be tackled: we can bring the total energy production up, by adding more panels or electricity by other means, but we can also try and bring the total demand down. This is to be achieved by investing strictly in the most energy-efficient appliances. Even replacing older, not-so-efficient appliances might sometimes be of use.
-But ensuring efficient use is not the only way to bring down the overall demand.
+
+
-As introduced as core ideas for the whole project, sharing and delaying will prove immensely useful. How so?
-By sharing, we mean a concept that is already widely applied in the relevant areas. What to do in a Village that has no access to water? Will we send each household out to the faraway river to catch water for their family? Or would we join hands in a community effort to dig a central well used by everyone?
+Auch wenn Solar nicht optimal ist – vor allem wegen Kälte und Batterielagerung – zeigte sich, dass **intelligente Lastverteilung** den nutzbaren Ertrag im Winter von einem Fünftel auf etwa die Hälfte steigern kann.
-So, when we look at sharing electricity, how would we apply the concept? We take the appliances that consume the most energy individually and scale them up in order to increase efficiency. For example, in our case, that is most applicable to electric heating. If we manage to heat central community spaces available for everyone, naturally, fewer individual rooms will have to be heated. Similarly, one could declare a room as a public cinema, where people come together and watch Tv on a big Projector. Twice as fun, and conserving a great deal of energy again. Such ideas and others have to be realized in order to be able to match the total demand with the available supply.
+## Schlusswort
-Sadly, the project was never taken up further, and the situation for the people in the Spiti Valley has not improved. Two years ago, a road directly through the mountains was finished, making the population hopeful for an increase in tourism, increasing the chances of the economic viability of improved solutions.
-I spent my time there in the function of a research intern, having no real say in the realization of the project. The problem remains, and I still think that decentral solutions look to be the most promising for this specific location. Of course, the Himalayas present a bit of an extreme location, but that doesn't change the fact that people live there and have a basic human right to electricity.
+Das Problem lässt sich aus zwei Richtungen angehen:
+1. **Produktion erhöhen** – mehr Module, mehr Energiequellen.
+2. **Verbrauch senken** – effizientere Geräte, gemeinschaftliche Nutzung.
+
+Das Konzept des **Teilens und Verzögerns** ist zentral. Wie bei einem gemeinschaftlich genutzten Brunnen kann auch Strom gemeinschaftlich erzeugt und genutzt werden.
+Gemeinsam beheizte Räume oder öffentliche Projekträume sparen Energie und fördern Gemeinschaft.
+
+Leider wurde das Projekt nie weitergeführt, und die Situation im Spiti-Tal hat sich kaum verbessert. Eine neue Bergstraße gibt Hoffnung auf mehr Tourismus – und damit auf wirtschaftlich tragfähige Lösungen.
+
+Ich selbst war als Forschungspraktikant beteiligt, ohne Einfluss auf die Umsetzung. Dennoch bin ich überzeugt, dass **dezentrale Lösungen** der richtige Weg sind – gerade für extreme Regionen wie den Himalaya.
+Denn eines bleibt wahr: **Elektrizität ist ein Menschenrecht.**

-Being involved with 3D Printers, there is the issue of sustainability that I am confronted with regularly.
-Most 3D printed parts never get recycled and add to the global waste problem, rather than reducing it.
-The printer most certainly doesn’t care what it is printing, the main problem is the dimensional accuracy and the purity of the material. All of this leads to a huge industry, Germany being especially involved, using loads of virgin plastic.
+Als 3D-Druck-Enthusiast sehe ich mich regelmäßig mit dem Thema Nachhaltigkeit konfrontiert.
+Die meisten 3D-gedruckten Teile werden nie recycelt und tragen eher zum globalen Müllproblem bei, als es zu reduzieren.
+Das Problem liegt weniger beim Drucker selbst als bei der **dimensionalen Genauigkeit** und der **Reinheit des Materials**. Dies führt zu einer riesigen Industrie, insbesondere in Deutschland, die enorme Mengen an **Neukunststoff** verbraucht.
-What can be done about it?
-We can design our products to last longer, we can also print recycling labels on them so they do not have to get burned after their first life. We can take care to only print functional objects, not just fun toys nobody uses.
-Yet, none of that prevents the use of virgin plastics. If you buy a spool of filament, there are some recycled options, but usually at twice the price at worse quality. No wonder recycled filament fails to convince the masses. It is mostly a fun thing YouTubers can pursue, not a valid commercial process.
+### Was kann man tun?
-{{ youtube(id="vqWwUx8l_Io") }}
+Wir können Produkte langlebiger gestalten, Recycling-Labels aufdrucken und nur funktionale Objekte drucken. Dennoch verhindert dies nicht die Nutzung von Neukunststoffen. Recycelter Filament ist oft doppelt so teuer bei schlechterer Qualität – kein Wunder, dass er kaum Verbreitung findet.
-In my opinion, the core problem is the nonexistent economic feasibility of a proper recycling process. Identifying the exact material of a piece of trash is a very hard problem, definitely not solved yet. So why do we mix the plastic up in the first place? There is a general willingness of people to recycle, but the system for it is missing.
+{{ youtube(id="vqWwUx8l_Io") }}
-# The Master Plan
+Das Kernproblem ist die **fehlende wirtschaftliche Machbarkeit** eines echten Recyclings. Das exakte Identifizieren von Kunststoffarten ist extrem schwierig und noch ungelöst. Es gibt Bereitschaft zu recyceln, aber das System fehlt.
-I want to get people to wash and separate their trash for me, which are the most expensive steps in the recycling process. There is a willingness to take the extra step, and even if just my mom collects bottle caps for me, that is more than I can realistically use up.
-This only really works when I am thinking in a local and decentral environment.
-The existing recycling facilities clearly will not be able to provide 200 different containers for 200 different types of plastic.
-Starting the process with clean and sorted materials, like bottle caps (HDPE) or failed prints (PET-G), I start off with an advantage.
-Now I have to take apart the trash into evenly sized particles.
-Meet:
+# Der Masterplan
-## The Shredder
+Ich möchte Menschen motivieren, ihren Müll **zu waschen und zu sortieren**, die teuersten Schritte im Recyclingprozess. Selbst kleine Beiträge, wie meine Mutter, die Flaschendeckel sammelt, sind wertvoll.
+Dies funktioniert nur in einem **lokalen, dezentralen Umfeld**. Existierende Recyclinganlagen können nicht 200 verschiedene Kunststoffarten trennen.
-We built the Precious Plastic Shredder!
+Mit sauberem, sortiertem Material – etwa Flaschendeckel (HDPE) oder fehlerhafte Drucke (PET-G) – starte ich bereits im Vorteil. Jetzt müssen die Teile noch in **gleichmäßige Partikel** zerkleinert werden.
-
+## Der Shredder
-With these awesome open-source drawings, I was able to cobble together my very own very dangerous plastic shredder.
+Wir bauten den **Precious Plastic Shredder**!
-After finding some way to drive this massive axis, I feed the beast and hopefully get tiny pretty uniform plastic bits that are ready to begin the cycle of life anew.
+
-The solution for the motorization was an old and used garden shredder that still had an intact motor and wiring.
-We cut it in half and attached it to the shredder box.
+Mit diesen Open-Source-Zeichnungen konnte ich meinen eigenen, sehr gefährlichen Kunststoff-Shredder zusammenbauen.
+Die Motorisierung übernahm ein alter Gartenschredder, der Motor und Verkabelung intakt hatte. Wir schnitten ihn auseinander und befestigten ihn am Shredder.
-{{ youtube(id="QwVp1zmAA4Q") }}
+{{ youtube(id="QwVp1zmAA4Q") }}
-After replacing the weak force transmission screw for an industrial coupler, we were ready to try it out. Obviously, there are still security concerns in this prototype, a proper hopper is already being made.
+Nach Austausch der schwachen Kraftübertragungsschraube gegen einen Industrie-Kuppler waren wir startklar. Sicherheit bleibt ein Thema, ein richtiger Trichter ist in Arbeit.
-Nevertheless, we are confident that this shredder will be able to deal with the light sorts of plastic we are thinking of.
-As you can see, I am now able to produce awesome confetti but to do more with the plastic flakes I have to extrude them.
+## Der Filastruder
-## Meet the Filastruder
+Der **Filastruder**, entworfen von Tim Elmore, bietet eine kostengünstige Möglichkeit, Filament zu extrudieren.
+Die größten Herausforderungen: **präzise Durchmesserkontrolle** ±0,03 mm, sonst schwankt die Qualität.
-This is the Filastruder, designed and made by Tim Elmore, in an attempt to create the cheapest viable way to extrude plastic. The biggest cost issue is the tight industrial tolerances in thickness that have to be adhered to. This is in essence what separates good from the bad filament. The industry standard nowadays is at +-0.03mm. Hard to achieve on a DIY setup, but not unheard of. The setup, like any bigger industry equivalent, consists of a motor pressing plastic pellets through a heated screw, extruding molten plastic at the end through a nozzle, and setting the diameter. The leftmost machine is responsible for winding the filament properly onto a spool.
+Motor presst Kunststoffpellets durch eine beheizte Schraube, am Ende wird durch die Düse extrudiert und der Durchmesser eingestellt. Links wickelt die Maschine das Filament auf eine Spule.
-Here you can see the extrusion process in action.

-{{ youtube(id="FX6--pYrPVs") }}
+Der Filastruder wird von einem **Arduino gesteuert** und ist hoch konfigurierbar. Ein Lasersensor misst den Filamentdurchmesser.
-The Filastruder is controlled by an Arduino and is highly configurable. The laser sensor visible in the video is already working, but I am missing more direct control over the diameter of the filament.
+### Machine Learning für optimale Filamentqualität
-When it all really comes down to the single variable of the filament diameter responsible for the quality of my recycled project, a simple Machine Learning optimization directly jumps at me: I have a few variables like winder speed, extrusion speed, heat, and cooling intensity. These variables can be optimized on the fly for an exact diameter. This is actually roughly how virgin filament is produced, commercial facilities just manage much faster.
+Wichtige Variablen: Wickelgeschwindigkeit, Extrusionsgeschwindigkeit, Temperatur, Kühlung.
+Diese Variablen können **in Echtzeit optimiert** werden – ähnlich wie in kommerziellen Anlagen.

-So far, I am aware of a few companies and academic projects attempting this process, but none of them manage to get either the quality or the price of other products available. Automatization does not just take out jobs away, I think it can also be a helpful tool, for example tackling environmental issues such as this one.
+Automatisierung ist nicht nur ein Jobkiller, sondern kann Umweltprobleme lösen.
-This project is very dear to my heart and I plan to investigate it further in the form of a master thesis.
-The realization will require many skills I am already picking up or still need to work on within the Design and Computation program.

-## Ballpark: 3D Environments in Unity
+## Ballpark: 3D-Umgebungen in Unity
-Implemented in Unity, Ballpark is a Concept work for a collaborative 2-Player Game, where one player is a navigator with a third-person perspective and another player is a copilot, responsible for interaction with the environment – featuring mostly working physics, intelligent enemies, a gun, a grappling hook system for traversing the map, a 2D Interface for navigation and a health bar system. On top of the meanest cyberpunk vibes my past self was able to conjure.
+Umgesetzt in Unity, ist **Ballpark** ein Konzept für ein **kooperatives 2-Spieler-Spiel**, bei dem ein Spieler als Navigator mit einer Third-Person-Perspektive agiert und der andere Spieler als Copilot für die Interaktion mit der Umgebung zuständig ist.
+Das Spiel verfügt über funktionierende Physik, intelligente Gegner, eine Waffe, ein Greifhaken-System zum Überqueren der Karte, eine 2D-Navigationsoberfläche und ein Health-Bar-System – alles mit den düstersten Cyberpunk-Vibes, die ich damals zusammenbringen konnte.
-Enjoy!
+Viel Spaß!

-As you can see, the design faces some questionable choices, but all mechanics are homemade from the ground up and I learned a lot. I often struggle to enjoy competitive games and think there is potential in a co-dependent game interface. During early testing, we often found that it enforces player communication since already the tutorial is quite hard to beat.
-Due to me being a leftie, perhaps not entirely smart, I gave player one the keyboard arrows to work with and player two the WASD keys and left and right mouse buttons for grappling and shooting. For the game, it has an interesting side effect, in that players are forced not only to interact through the differing information on each player's screen but also have to physically interact and coordinate the controls.
+Das Design enthält einige fragwürdige Entscheidungen, aber alle Mechaniken sind **von Grund auf selbst entwickelt**, und ich habe viel dabei gelernt. Ich spiele selten kompetitive Spiele, sehe aber Potenzial in einer **kooperativen, voneinander abhängigen Spielmechanik**. Schon das Tutorial erfordert intensive Spielerkommunikation.
-As you can perhaps see, the ball-rolling navigation is quite hard to use.
-It is a purely physics-based system, where, depending on the materiality of the ball, its weight, and therefore its inertia will drastically change.
+Als Linkshänder habe ich Spieler eins die Pfeiltasten gegeben und Spieler zwei die WASD-Tasten sowie die linken und rechten Maustasten für Schießen und Greifhaken. Das führt zu einem interessanten Nebeneffekt: Spieler müssen nicht nur über unterschiedliche Informationen auf ihren Bildschirmen kommunizieren, sondern auch ihre Steuerung physisch koordinieren.
-On small screens, the prototype version of the game is virtually impossible to control and several visual bugs within the viewport still obfuscate items when they are too close. Considering that virtually all the mechanics are written from scratch, with a follow-me camera, collision detection, smart moving agents, and a still very wonky-looking grappling gun, I still think it deserves a spot in this portfolio.
-For this project I focused completely on the mechanics of the game, resulting in lots of used prefabs and readymade 3D Objects. Next time, I want to do that myself too.
+Die **Ball-Navigation** ist ziemlich schwer zu kontrollieren.
+Es handelt sich um ein **rein physikbasiertes System**, bei dem Material, Gewicht und Trägheit der Kugel die Bewegung stark beeinflussen.
-I enjoyed my stint into Unity a lot and am looking forward to creating my first VR application and would love to try out some form of mechanics where the user vision is completely obfuscated by VR and they have to carry their eyes as a handheld connected camera so that the players can move around the camera itself with their hands.
+Auf kleinen Bildschirmen ist die Steuerung praktisch unmöglich, und einige visuelle Bugs verdecken Objekte bei zu naher Ansicht. Dennoch, da fast alle Mechaniken von Grund auf programmiert wurden – inklusive Follow-Camera, Kollisionsabfrage, smarten Agenten und einem noch etwas wackeligen Greifhaken – verdient das Projekt einen Platz im Portfolio.
+
+Für dieses Projekt habe ich mich komplett auf **Mechaniken** konzentriert, weshalb viele fertige Prefabs und 3D-Objekte verwendet wurden. Beim nächsten Mal möchte ich diese auch selbst erstellen.
+
+Ich habe Unity sehr genossen und freue mich darauf, meine erste **VR-Anwendung** zu entwickeln.
+Ich möchte Mechaniken ausprobieren, bei denen die Sicht des Spielers durch VR komplett blockiert wird und die Augen als **tragbare, verbundene Kamera** bewegt werden, sodass die Spieler die Kamera selbst physisch steuern können.

-## Brewing
+## Brauen
-### Making my own beer
+### Mein eigenes Bier herstellen
-I love hosting, I love experimenting in the Kitchen. Starting with homebrews was a natural fit for me and during the first wave of Covid-19, I went the whole homebrewer’s route of bottle fermentation and small batches later elevating my game with larger batches of 50 liters and a pressure tank system.
+Ich liebe es zu veranstalten, ich liebe es, in der Küche zu experimentieren. Mit Homebrews zu starten, war für mich eine natürliche Entscheidung, und während der ersten Covid-19-Welle habe ich den kompletten Heimbräuerweg mit Flaschenfermentation und kleinen Chargen eingeschlagen, später habe ich mein Setup auf 50-Liter-Chargen mit Drucktank-System erweitert.
-Starting out, I found it fascinating, how just 4 rather simple ingredients, malt, hops, water and yeast, can form such an incredible range of taste experiences. It was and still is, a tremendous learning experience, where one slowly has to accept not being able to control the process fully and find room for creativity.
+Zu Beginn war ich fasziniert, wie aus nur **vier einfachen Zutaten** – Malz, Hopfen, Wasser und Hefe – ein so unglaubliches Spektrum an Geschmackserlebnissen entstehen kann. Es war und ist immer noch ein **tremendales Lernprojekt**, bei dem man langsam akzeptieren muss, dass man den Prozess nicht vollständig kontrollieren kann, und gleichzeitig Raum für Kreativität findet.
-Why do I present such an unrelated non-academic hobby here? I simply do not regard it as unrelated, experimenting and optimizing a process and a workflow, creating optimal conditions for the yeast to do its job feels very similar to approaching a coding project.
-Yeast and what it does fascinates me. Every time I open the latch to release some pressure on the Tank I think of the awesome symbiotic relationships yeast has with humans and how many different strains live there together to create a unique, yet tailored flavor. Several ideas are floating around of changing the brewing process by capturing the created carbon dioxide and using it productively. I could see a car tire being filled with my beer gas, or an algae farm munching away on my CO2 byproducts. Within a closed-loop pressurized system, such ideas actually become realizable and I would love to explore them further.
+Warum präsentiere ich dieses scheinbar nicht-akademische Hobby hier? Ich sehe es nicht als irrelevant an: **Experimentieren und Optimieren eines Prozesses und Workflows**, optimale Bedingungen für die Hefe zu schaffen, fühlt sich dem Ansatz eines Programmierprojekts sehr ähnlich an.
-I am not yet an expert on algae, but I can manage with yeast and I believe they can coexist and create a more sustainable cycle of production.
-Young Henrys, a brewery in Australia is already incorporating algae into its industrial process:
- [The Algae project](https://younghenrys.com/algae)
+Hefe und ihre Wirkung faszinieren mich. Jedes Mal, wenn ich den Verschluss öffne, um etwas Druck aus dem Tank abzulassen, denke ich an die erstaunlichen symbiotischen Beziehungen der Hefe mit Menschen und wie viele verschiedene Stämme zusammenleben, um einen einzigartigen, maßgeschneiderten Geschmack zu erzeugen.
+Es gibt einige Ideen, den Brauprozess zu verändern, indem das erzeugte CO₂ aufgefangen und produktiv genutzt wird – z. B. ein Autoreifen gefüllt mit Biergas oder eine Algenfarm, die das CO₂ aufnimmt. Innerhalb eines **geschlossenen, druckbeaufschlagten Systems** werden solche Ideen tatsächlich realisierbar, und ich möchte sie weiter erforschen.
-Such ideas do not come into the industry by themselves: I believe that art and the exploratory discovery of novel techniques are the same things. Good and inventive design can improve society and make steps towards sustainability. I want to be part of that and would love to find new ways of using yeast in other design contexts: See whether I can make them work in a closed circular system, make them calculate things for me, or simply making my next beer taste awesome with just the right amount of fizz.
+Ich bin noch kein Experte für Algen, aber mit Hefe komme ich klar, und ich glaube, dass sie koexistieren und einen nachhaltigeren Produktionszyklus schaffen können.
+Die australische Brauerei Young Henrys integriert Algen bereits in ihren industriellen Prozess: [The Algae project](https://younghenrys.com/algae)
+
+Solche Ideen kommen nicht von selbst in die Industrie: Ich glaube, dass Kunst und die experimentelle Entdeckung neuer Techniken dasselbe sind. **Gutes, erfinderisches Design** kann die Gesellschaft verbessern und Schritte in Richtung Nachhaltigkeit gehen. Ich möchte daran teilhaben und neue Wege finden, Hefe in anderen Designkontexten einzusetzen: ob in einem geschlossenen Kreislaufsystem, zum Berechnen von Dingen oder einfach, um mein nächstes Bier mit der perfekten Spritzigkeit zu brauen.

-## 2020: discovering jekyll
+## 2020: Jekyll entdecken
-For applying to my master's program in 2020, a portfolio was required, and since it was more or less for a design program, I wanted to have a nice website.
-After trying for a month to get what I wanted out of WordPress, and angrily quitting multiple times, I discovered [Jekyll](https://jekyllrb.com).
-Back then, [Hugo](https://gohugo.io) and [11ty](https://www.11ty.dev) were the newer kids on the block, but I was heavily relying on the free hosting from [GitHub Pages](https://pages.github.com), where Jekyll was the easiest to integrate.
+Für meine Bewerbung zum Masterstudium 2020 war ein Portfolio erforderlich, und da es mehr oder weniger für ein Designprogramm war, wollte ich eine schöne Website haben.
+Nach einem Monat frustrierender Versuche, WordPress nach meinen Wünschen anzupassen, entdeckte ich [Jekyll](https://jekyllrb.com).
+Damals waren [Hugo](https://gohugo.io) und [11ty](https://www.11ty.dev) die neuen Tools, aber ich nutzte stark das kostenlose Hosting von [GitHub Pages](https://pages.github.com), bei dem Jekyll am einfachsten zu integrieren war.
-Back then, looking for inspiration, I had an ethics professor I really liked, and he had a Jekyll site with the [Minimal Mistakes](https://mmistakes.github.io/minimal-mistakes/) theme.
-[Prof. Mühlhoff](https://rainermuehlhoff.de)
+Auf der Suche nach Inspiration hatte ich einen Ethikprofessor, den ich sehr mochte, und er hatte eine Jekyll-Seite mit dem [Minimal Mistakes](https://mmistakes.github.io/minimal-mistakes/) Theme.
+[Prof. Mühlhoff](https://rainermuehlhoff.de)
-I went about using Minimal Mistakes, and it was a great experience.
-The resulting portfolio at least got me into the master's, and I fell in love with the general idea of being able to write sites in markdown, while a program would take care of the rest.
+Ich begann, Minimal Mistakes zu verwenden, und es war eine großartige Erfahrung.
+Das daraus entstandene Portfolio brachte mich zumindest in den Masterstudiengang, und ich verliebte mich in die Idee, Websites in Markdown schreiben zu können, während ein Programm sich um den Rest kümmert.
-For years, Jekyll was my go-to for building static websites.
-It was familiar, widely supported, and part of the broader Ruby ecosystem.
-But over time, my frustrations grew—slow builds, complicated plugin setups, and a dependency stack that never felt quite right.
-To be honest, many of the drawbacks were totally not Jekyll’s fault. It was just slow, otherwise fine. But especially using GitHub Pages imposed quite a few limitations on plugins and themes.
-Also, maybe I didn’t put in enough effort, but I could never really get theme modifications working. Just extending the theme to show multiple authors was a pain—although it was eventually working.
+Jahrelang war Jekyll mein Standard für statische Websites.
+Es war vertraut, weit verbreitet und Teil des Ruby-Ökosystems.
+Mit der Zeit wuchsen jedoch meine Frustrationen – langsame Builds, komplizierte Plugin-Setups und ein Abhängigkeitsstapel, der nie ganz passte.
+Um ehrlich zu sein, viele Nachteile lagen überhaupt nicht an Jekyll. Es war nur langsam, ansonsten funktionierte alles. Aber besonders GitHub Pages schränkte Plugins und Themes stark ein.
+Auch habe ich vielleicht nicht genug Mühe investiert, aber Theme-Anpassungen funktionierten nie so, wie ich wollte. Das Theme zu erweitern, um mehrere Autoren zu zeigen, war eine Qual – obwohl es schließlich funktionierte.
-On now finishing the master's, I wanted a visual overhaul, and while browsing for inspiration again, using Jekyll at all got questioned again.
-I knew I wanted a static site generator, because markdown is the shit.
-So after looking around further, **[Zola](https://www.getzola.org/)** emerged—actually through a chatbot suggestion 😄
+Nachdem ich nun den Master abgeschlossen hatte, wollte ich eine visuelle Überarbeitung, und die Nutzung von Jekyll wurde erneut hinterfragt.
+Ich wusste, dass ich einen statischen Site-Generator wollte, weil Markdown einfach großartig ist.
+Nach weiterer Recherche tauchte **[Zola](https://www.getzola.org/)** auf – tatsächlich durch einen Chatbot-Tipp 😄
-Recently, I made the leap to Zola, a Rust-powered static site generator, and I don't see myself going back.
+Kürzlich bin ich auf Zola, einen in Rust geschriebenen statischen Site-Generator, umgestiegen und sehe keinen Grund, zurückzugehen.
---
-## rust feels right
+## Rust fühlt sich richtig an
-I’ve always admired [Rust](https://www.rust-lang.org/) for its speed, safety, and modern tooling.
-Using a static site generator built with Rust just made sense. **Zola is fast**—blazing fast.
-Even during local development, rebuilds are near-instant, and that alone makes the writing process smoother and more enjoyable.
+Ich habe Rust immer für seine Geschwindigkeit, Sicherheit und modernen Tools bewundert.
+Einen statischen Site-Generator in Rust zu nutzen, machte einfach Sinn. **Zola ist schnell** – blitzschnell.
+Selbst bei der lokalen Entwicklung sind Neubauten quasi instant, was das Schreiben deutlich angenehmer macht.
-Plus, using something written in Rust means fewer external dependencies, no bundler hell, and zero Ruby setup headaches.
-I can just download the binary, run it, and get going. It respects my time.
+Außerdem bedeutet etwas in Rust Geschriebenes weniger externe Abhängigkeiten, kein Bundler-Chaos und keine Ruby-Installationsprobleme.
+Ich kann einfach die Binary herunterladen, ausführen und loslegen. Es respektiert meine Zeit.
---
-## zola is thoughtfully designed
+## Zola ist durchdacht gestaltet
-Beyond performance, Zola is just really well designed.
-Its template syntax (thanks to [Tera](https://tera.netlify.app)) is more powerful and readable than Liquid.
-The built-in shortcodes, pagination, and asset pipelines all feel cohesive and purposeful.
-There’s very little “configuration over convention” fatigue that Jekyll often gave me.
+Neben der Performance ist Zola einfach gut durchdacht.
+Seine Templatesyntax (dank [Tera](https://tera.netlify.app)) ist leistungsfähiger und lesbarer als Liquid.
+Die eingebauten Shortcodes, Paginierung und Asset-Pipelines wirken alle kohärent und sinnvoll.
+Es gibt kaum „Konfiguration statt Konvention“-Müdigkeit, wie sie Jekyll oft erzeugte.
-And even though both systems are markdown-based, migrating wasn’t just a matter of copy-pasting files.
-I had to rethink frontmatter, adjust templates, and wrangle image paths and shortcodes.
-The structure and behavior are different enough that it felt like a real rebuild—not just a port.
+Und obwohl beide Systeme Markdown-basiert sind, war Migration nicht einfach nur Copy-Paste.
+Ich musste Frontmatter überdenken, Templates anpassen und Bildpfade sowie Shortcodes anpassen.
+Struktur und Verhalten unterscheiden sich genug, sodass es sich wie ein echtes Rebuild anfühlte – nicht nur ein Port.
---
-## duckquill made me switch
+## Duckquill hat mich überzeugt
-The real catalyst, though? [**Duckquill**](https://github.com/daudix/duckquill), a stunning Zola theme built by [Daudix](https://github.com/daudix).
-It struck the perfect balance between minimalism and elegance—exactly the aesthetic I wanted but could never quite achieve with Jekyll.
-Duckquill didn’t just make Zola usable for me; it made it _irresistible_.
+Der eigentliche Auslöser? [**Duckquill**](https://github.com/daudix/duckquill), ein beeindruckendes Zola-Theme von [Daudix](https://github.com/daudix).
+Es fand die perfekte Balance zwischen Minimalismus und Eleganz – genau die Ästhetik, die ich wollte, aber mit Jekyll nie erreichte.
+Duckquill machte Zola für mich nicht nur nutzbar; es machte es _unwiderstehlich_.
-What really sets **Duckquill** apart—beyond its clean typography and smart layout—is how well it supports a vision of digital autonomy.
-The theme comes with **Mastodon-powered comments**, allowing for lightweight, federated interaction without relying on big centralized platforms.
-This fits perfectly with my goal of reclaiming control through **self-hosting**.
-Whether it's running my own site, owning my content, or interacting through the fediverse, Duckquill reinforces those values rather than working against them.
-It’s a rare example of design and infrastructure aligning with personal principles.
+Besonders hervorzuheben – neben der klaren Typografie und dem smarten Layout – ist, wie gut es digitale Autonomie unterstützt.
+Das Theme bietet **Mastodon-basierte Kommentare**, was leichte, föderierte Interaktion erlaubt, ohne auf große zentrale Plattformen angewiesen zu sein.
+Das passt perfekt zu meinem Ziel der **Selbsthostung**.
+Ob eigene Website, Kontrolle über Inhalte oder Interaktion über das Fediverse – Duckquill unterstützt diese Werte, statt dagegen zu arbeiten.
+Ein seltenes Beispiel, in dem Design und Infrastruktur mit persönlichen Prinzipien übereinstimmen.
---
-## final thoughts
+## Fazit
-Switching from Jekyll to Zola wasn’t effortless, but it was absolutely worth it.
-I now have a faster, more reliable, and better-looking site that’s easier to maintain and feels like it fits my tooling philosophy.
+Der Wechsel von Jekyll zu Zola war nicht mühelos, aber absolut lohnenswert.
+Ich habe jetzt eine schnellere, zuverlässigere und besser aussehende Website, die leichter zu warten ist und besser zu meiner Tooling-Philosophie passt.
-If you're feeling the weight of your current setup, maybe it's time to try Zola—and give Duckquill a spin while you're at it.
+Wenn du das Gewicht deines aktuellen Setups spürst, könnte es Zeit sein, Zola auszuprobieren – und Duckquill gleich mit.

- <h2 id="2020:_discovering_jekyll">2020: discovering jekyll</h2>
-<p>For applying to my master's program in 2020, a portfolio was required, and since it was more or less for a design program, I wanted to have a nice website.
-After trying for a month to get what I wanted out of WordPress, and angrily quitting multiple times, I discovered <a href="https://jekyllrb.com">Jekyll</a>.
-Back then, <a href="https://gohugo.io">Hugo</a> and <a href="https://www.11ty.dev">11ty</a> were the newer kids on the block, but I was heavily relying on the free hosting from <a href="https://pages.github.com">GitHub Pages</a>, where Jekyll was the easiest to integrate.</p>
-<p>Back then, looking for inspiration, I had an ethics professor I really liked, and he had a Jekyll site with the <a href="https://mmistakes.github.io/minimal-mistakes/">Minimal Mistakes</a> theme.
-<a href="https://rainermuehlhoff.de">Prof. Mühlhoff</a></p>
-<p>I went about using Minimal Mistakes, and it was a great experience.
-The resulting portfolio at least got me into the master's, and I fell in love with the general idea of being able to write sites in markdown, while a program would take care of the rest.</p>
-<p>For years, Jekyll was my go-to for building static websites.
-It was familiar, widely supported, and part of the broader Ruby ecosystem.
-But over time, my frustrations grew—slow builds, complicated plugin setups, and a dependency stack that never felt quite right.
-To be honest, many of the drawbacks were totally not Jekyll’s fault. It was just slow, otherwise fine. But especially using GitHub Pages imposed quite a few limitations on plugins and themes.
-Also, maybe I didn’t put in enough effort, but I could never really get theme modifications working. Just extending the theme to show multiple authors was a pain—although it was eventually working.</p>
-<p>On now finishing the master's, I wanted a visual overhaul, and while browsing for inspiration again, using Jekyll at all got questioned again.
-I knew I wanted a static site generator, because markdown is the shit.
-So after looking around further, <strong><a href="https://www.getzola.org/">Zola</a></strong> emerged—actually through a chatbot suggestion 😄</p>
-<p>Recently, I made the leap to Zola, a Rust-powered static site generator, and I don't see myself going back.</p>
-<hr />
-<h2 id="rust_feels_right">rust feels right</h2>
-<p>I’ve always admired <a href="https://www.rust-lang.org/">Rust</a> for its speed, safety, and modern tooling.
-Using a static site generator built with Rust just made sense. <strong>Zola is fast</strong>—blazing fast.
-Even during local development, rebuilds are near-instant, and that alone makes the writing process smoother and more enjoyable.</p>
-<p>Plus, using something written in Rust means fewer external dependencies, no bundler hell, and zero Ruby setup headaches.
-I can just download the binary, run it, and get going. It respects my time.</p>
-<hr />
-<h2 id="zola_is_thoughtfully_designed">zola is thoughtfully designed</h2>
-<p>Beyond performance, Zola is just really well designed.
-Its template syntax (thanks to <a href="https://tera.netlify.app">Tera</a>) is more powerful and readable than Liquid.
-The built-in shortcodes, pagination, and asset pipelines all feel cohesive and purposeful.
-There’s very little “configuration over convention” fatigue that Jekyll often gave me.</p>
-<p>And even though both systems are markdown-based, migrating wasn’t just a matter of copy-pasting files.
-I had to rethink frontmatter, adjust templates, and wrangle image paths and shortcodes.
-The structure and behavior are different enough that it felt like a real rebuild—not just a port.</p>
-<hr />
-<h2 id="duckquill_made_me_switch">duckquill made me switch</h2>
-<p>The real catalyst, though? <a href="https://github.com/daudix/duckquill"><strong>Duckquill</strong></a>, a stunning Zola theme built by <a href="https://github.com/daudix">Daudix</a>.
-It struck the perfect balance between minimalism and elegance—exactly the aesthetic I wanted but could never quite achieve with Jekyll.
-Duckquill didn’t just make Zola usable for me; it made it <em>irresistible</em>.</p>
-<p>What really sets <strong>Duckquill</strong> apart—beyond its clean typography and smart layout—is how well it supports a vision of digital autonomy.
-The theme comes with <strong>Mastodon-powered comments</strong>, allowing for lightweight, federated interaction without relying on big centralized platforms.
-This fits perfectly with my goal of reclaiming control through <strong>self-hosting</strong>.
-Whether it's running my own site, owning my content, or interacting through the fediverse, Duckquill reinforces those values rather than working against them.
-It’s a rare example of design and infrastructure aligning with personal principles.</p>
-<hr />
-<h2 id="final_thoughts">final thoughts</h2>
-<p>Switching from Jekyll to Zola wasn’t effortless, but it was absolutely worth it.
-I now have a faster, more reliable, and better-looking site that’s easier to maintain and feels like it fits my tooling philosophy.</p>
-<p>If you're feeling the weight of your current setup, maybe it's time to try Zola—and give Duckquill a spin while you're at it.</p>

-<p>As you can see, the design faces some questionable choices, but all mechanics are homemade from the ground up and I learned a lot. I often struggle to enjoy competitive games and think there is potential in a co-dependent game interface. During early testing, we often found that it enforces player communication since already the tutorial is quite hard to beat.
-Due to me being a leftie, perhaps not entirely smart, I gave player one the keyboard arrows to work with and player two the WASD keys and left and right mouse buttons for grappling and shooting. For the game, it has an interesting side effect, in that players are forced not only to interact through the differing information on each player's screen but also have to physically interact and coordinate the controls.</p>
-<p>As you can perhaps see, the ball-rolling navigation is quite hard to use.
-It is a purely physics-based system, where, depending on the materiality of the ball, its weight, and therefore its inertia will drastically change.</p>
-<p>On small screens, the prototype version of the game is virtually impossible to control and several visual bugs within the viewport still obfuscate items when they are too close. Considering that virtually all the mechanics are written from scratch, with a follow-me camera, collision detection, smart moving agents, and a still very wonky-looking grappling gun, I still think it deserves a spot in this portfolio.
-For this project I focused completely on the mechanics of the game, resulting in lots of used prefabs and readymade 3D Objects. Next time, I want to do that myself too.</p>
-<p>I enjoyed my stint into Unity a lot and am looking forward to creating my first VR application and would love to try out some form of mechanics where the user vision is completely obfuscated by VR and they have to carry their eyes as a handheld connected camera so that the players can move around the camera itself with their hands.</p>
+<p>Das Design enthält einige fragwürdige Entscheidungen, aber alle Mechaniken sind <strong>von Grund auf selbst entwickelt</strong>, und ich habe viel dabei gelernt. Ich spiele selten kompetitive Spiele, sehe aber Potenzial in einer <strong>kooperativen, voneinander abhängigen Spielmechanik</strong>. Schon das Tutorial erfordert intensive Spielerkommunikation.</p>
+<p>Als Linkshänder habe ich Spieler eins die Pfeiltasten gegeben und Spieler zwei die WASD-Tasten sowie die linken und rechten Maustasten für Schießen und Greifhaken. Das führt zu einem interessanten Nebeneffekt: Spieler müssen nicht nur über unterschiedliche Informationen auf ihren Bildschirmen kommunizieren, sondern auch ihre Steuerung physisch koordinieren.</p>
+<p>Die <strong>Ball-Navigation</strong> ist ziemlich schwer zu kontrollieren.<br />
+Es handelt sich um ein <strong>rein physikbasiertes System</strong>, bei dem Material, Gewicht und Trägheit der Kugel die Bewegung stark beeinflussen.</p>
+<p>Auf kleinen Bildschirmen ist die Steuerung praktisch unmöglich, und einige visuelle Bugs verdecken Objekte bei zu naher Ansicht. Dennoch, da fast alle Mechaniken von Grund auf programmiert wurden – inklusive Follow-Camera, Kollisionsabfrage, smarten Agenten und einem noch etwas wackeligen Greifhaken – verdient das Projekt einen Platz im Portfolio.</p>
+<p>Für dieses Projekt habe ich mich komplett auf <strong>Mechaniken</strong> konzentriert, weshalb viele fertige Prefabs und 3D-Objekte verwendet wurden. Beim nächsten Mal möchte ich diese auch selbst erstellen.</p>

-<p>I love hosting, I love experimenting in the Kitchen. Starting with homebrews was a natural fit for me and during the first wave of Covid-19, I went the whole homebrewer’s route of bottle fermentation and small batches later elevating my game with larger batches of 50 liters and a pressure tank system.</p>
-<p>Starting out, I found it fascinating, how just 4 rather simple ingredients, malt, hops, water and yeast, can form such an incredible range of taste experiences. It was and still is, a tremendous learning experience, where one slowly has to accept not being able to control the process fully and find room for creativity.</p>
-<p>Why do I present such an unrelated non-academic hobby here? I simply do not regard it as unrelated, experimenting and optimizing a process and a workflow, creating optimal conditions for the yeast to do its job feels very similar to approaching a coding project.
-Yeast and what it does fascinates me. Every time I open the latch to release some pressure on the Tank I think of the awesome symbiotic relationships yeast has with humans and how many different strains live there together to create a unique, yet tailored flavor. Several ideas are floating around of changing the brewing process by capturing the created carbon dioxide and using it productively. I could see a car tire being filled with my beer gas, or an algae farm munching away on my CO2 byproducts. Within a closed-loop pressurized system, such ideas actually become realizable and I would love to explore them further.</p>
-<p>I am not yet an expert on algae, but I can manage with yeast and I believe they can coexist and create a more sustainable cycle of production.
-Young Henrys, a brewery in Australia is already incorporating algae into its industrial process:
-<a href="https://younghenrys.com/algae">The Algae project</a></p>
-<p>Such ideas do not come into the industry by themselves: I believe that art and the exploratory discovery of novel techniques are the same things. Good and inventive design can improve society and make steps towards sustainability. I want to be part of that and would love to find new ways of using yeast in other design contexts: See whether I can make them work in a closed circular system, make them calculate things for me, or simply making my next beer taste awesome with just the right amount of fizz.</p>

+<p>Ich liebe es zu veranstalten, ich liebe es, in der Küche zu experimentieren. Mit Homebrews zu starten, war für mich eine natürliche Entscheidung, und während der ersten Covid-19-Welle habe ich den kompletten Heimbräuerweg mit Flaschenfermentation und kleinen Chargen eingeschlagen, später habe ich mein Setup auf 50-Liter-Chargen mit Drucktank-System erweitert.</p>
+<p>Zu Beginn war ich fasziniert, wie aus nur <strong>vier einfachen Zutaten</strong> – Malz, Hopfen, Wasser und Hefe – ein so unglaubliches Spektrum an Geschmackserlebnissen entstehen kann. Es war und ist immer noch ein <strong>tremendales Lernprojekt</strong>, bei dem man langsam akzeptieren muss, dass man den Prozess nicht vollständig kontrollieren kann, und gleichzeitig Raum für Kreativität findet.</p>
+<p>Warum präsentiere ich dieses scheinbar nicht-akademische Hobby hier? Ich sehe es nicht als irrelevant an: <strong>Experimentieren und Optimieren eines Prozesses und Workflows</strong>, optimale Bedingungen für die Hefe zu schaffen, fühlt sich dem Ansatz eines Programmierprojekts sehr ähnlich an.</p>
+<p>Hefe und ihre Wirkung faszinieren mich. Jedes Mal, wenn ich den Verschluss öffne, um etwas Druck aus dem Tank abzulassen, denke ich an die erstaunlichen symbiotischen Beziehungen der Hefe mit Menschen und wie viele verschiedene Stämme zusammenleben, um einen einzigartigen, maßgeschneiderten Geschmack zu erzeugen.<br />
+Es gibt einige Ideen, den Brauprozess zu verändern, indem das erzeugte CO₂ aufgefangen und produktiv genutzt wird – z. B. ein Autoreifen gefüllt mit Biergas oder eine Algenfarm, die das CO₂ aufnimmt. Innerhalb eines <strong>geschlossenen, druckbeaufschlagten Systems</strong> werden solche Ideen tatsächlich realisierbar, und ich möchte sie weiter erforschen.</p>
+<p>Ich bin noch kein Experte für Algen, aber mit Hefe komme ich klar, und ich glaube, dass sie koexistieren und einen nachhaltigeren Produktionszyklus schaffen können.<br />
+Die australische Brauerei Young Henrys integriert Algen bereits in ihren industriellen Prozess: <a href="https://younghenrys.com/algae">The Algae project</a></p>
+<p>Solche Ideen kommen nicht von selbst in die Industrie: Ich glaube, dass Kunst und die experimentelle Entdeckung neuer Techniken dasselbe sind. <strong>Gutes, erfinderisches Design</strong> kann die Gesellschaft verbessern und Schritte in Richtung Nachhaltigkeit gehen. Ich möchte daran teilhaben und neue Wege finden, Hefe in anderen Designkontexten einzusetzen: ob in einem geschlossenen Kreislaufsystem, zum Berechnen von Dingen oder einfach, um mein nächstes Bier mit der perfekten Spritzigkeit zu brauen.</p>

- <p>Being involved with 3D Printers, there is the issue of sustainability that I am confronted with regularly.
-Most 3D printed parts never get recycled and add to the global waste problem, rather than reducing it.
-The printer most certainly doesn’t care what it is printing, the main problem is the dimensional accuracy and the purity of the material. All of this leads to a huge industry, Germany being especially involved, using loads of virgin plastic.</p>
-<p>What can be done about it?
-We can design our products to last longer, we can also print recycling labels on them so they do not have to get burned after their first life. We can take care to only print functional objects, not just fun toys nobody uses.
-Yet, none of that prevents the use of virgin plastics. If you buy a spool of filament, there are some recycled options, but usually at twice the price at worse quality. No wonder recycled filament fails to convince the masses. It is mostly a fun thing YouTubers can pursue, not a valid commercial process.</p>

-The existing recycling facilities clearly will not be able to provide 200 different containers for 200 different types of plastic.

The industry standard nowadays is at +-0.03mm. Hard to achieve on a DIY setup, but not unheard of. The setup, like any bigger industry equivalent, consists of a motor pressing plastic pellets through a heated screw, extruding molten plastic at the end through a nozzle, and setting the diameter.

-<p>The Filastruder is controlled by an Arduino and is highly configurable. The laser sensor visible in the video is already working, but I am missing more direct control over the diameter of the filament.</p>
-<p>When it all really comes down to the single variable of the filament diameter responsible for the quality of my recycled project, a simple Machine Learning optimization directly jumps at me: I have a few variables like winder speed, extrusion speed, heat, and cooling intensity. These variables can be optimized on the fly for an exact diameter. This is actually roughly how virgin filament is produced, commercial facilities just manage much faster.</p>

-<p>So far, I am aware of a few companies and academic projects attempting this process, but none of them manage to get either the quality or the price of other products available. Automatization does not just take out jobs away, I think it can also be a helpful tool, for example tackling environmental issues such as this one.</p>
-<p>This project is very dear to my heart and I plan to investigate it further in the form of a master thesis.
-The realization will require many skills I am already picking up or still need to work on within the Design and Computation program.

-<p>Access to Electricity is a basic human right. At first, that may seem over the top, but if one stops to think what all the little tasks that electricity can indirectly handle for us (lightning, laundry, cooking, freezing, heating, entertaining…) would consume in time and effort if we had to perform them manually, this idea becomes very clear. There are globally around 1 billion people without tier 2 access to electricity.</p>

-<p>People only know the intensity of labor that goes into everything when there is no electricity. And it is not even only about convenience, electricity is an enormous lifesaver in any number of scenarios, think just of hospitals or mobile phone networks that would be rendered completely useless without it. So we can easily agree on a need, a demand for electricity globally, for every person. But what about the supply? Why is there 1 billion undersupplied?
-The Answer: missing profitability. It would be a charity project to supply every last person on earth, not a profitable one. And while charitable projects are noble and should be pursued, the reality within capitalism shows that this is not the way it is going to happen.
-But what if we could come up with technology, or rather, a communal structure, that enables us to supply profitably, and still adapt to both, the difficult external factors (weather issues, remoteness, altitude, etc.) and the smaller purses of the undersupplied?</p>

+<p>Zugang zu Elektrizität ist ein grundlegendes Menschenrecht. Das mag zunächst übertrieben klingen, doch wenn man bedenkt, wie viele kleine Aufgaben der Strom uns indirekt abnimmt – Licht, Wäsche, Kochen, Kühlen, Heizen, Unterhaltung – wird schnell klar, wie viel Zeit und Aufwand ohne Elektrizität nötig wäre. Weltweit leben etwa <strong>eine Milliarde Menschen</strong> ohne Zugang zu Strom auf dem sogenannten Tier-2-Level.</p>

+<p>Menschen erkennen erst dann, wie viel Arbeit in alltäglichen Dingen steckt, wenn sie keinen Strom haben. Doch es geht dabei nicht nur um Bequemlichkeit – Elektrizität rettet Leben: Krankenhäuser, Telekommunikation, Kühlung von Medikamenten – all das hängt davon ab.<br />
+Warum also sind immer noch so viele Menschen unterversorgt?<br />
+<strong>Die Antwort: fehlende Rentabilität.</strong> Es wäre ein wohltätiges, aber kein profitables Projekt, jede Person auf der Welt zu versorgen. Doch was, wenn wir eine Struktur finden könnten, die <strong>wirtschaftlich tragfähig</strong> ist und sich gleichzeitig an schwierige Bedingungen (Wetter, Abgeschiedenheit, Höhenlage) sowie an kleinere Einkommen anpassen kann?</p>

-<h2 id="The_Project">The Project</h2>
-<p>In an environment reliant on hydro-energy and solar (diesel transport is unreliable due to snowed-in mountain roads), over 6 months of snowy winter, frequent snowstorms, and temperatures of up to -35°C, securing the grid is hard.</p>
-<p>Our way to tackle the issue was to reject the in the western society very established notion of electricity as a homogenous product with centralized production and instead researched the possibilities of a predictive, self-correcting, and decentral grid.</p>
-<p>By prioritizing energy usage cases, instead of a full blackout during a storm, essential functions like radio towers and hospitals could be partially powered and maybe stay functioning. The binarity of either having electricity or not would be replaced by assigned quantities and timeslots, in a collective effort to be mindful and distribute the electricity necessity-based.
-The ultimate vision was a live predictive electricity market, where people could even earn money by selling their allotted, but not needed electricity.
-To gauge feasibility, I conducted several psychological acceptance studies and collected data on local electricity demands.
-I simulated a typical day of electricity demand in the Key monastery and the surrounding villages and mapped out the potential to install cost-efficient smart microgrid controllers enabling such an accurate and predictive behavior.
-The smart grid operator boxes available here in Germany cost several hundred, with installation several thousand Euros, not a feasible solution for the Indian population. Instead, we wanted to use Raspberry Pi's, which are interconnected through ethernet cables or local mesh networking.</p>
-<h2 id="Research">Research</h2>
-<p><img src="/images/Key_Monastery_Spiti.png" alt="The Electricity layout of the Key Monastery" /></p>
-<h2 id="Data_Collection">Data Collection</h2>
-<p>Building a questionnaire and visiting public schools during their English Classes, I had the chance to speak to a range of teenagers, answering questions about the state of electricity in their homes, generating more data than I could have accomplished running from door to door without any skills speaking local dialects. The questionnaire was as scientific as I could make it in such a situation and geared towards finding the type and number of electric devices in the homes and estimating typical usage scenarios.</p>
-<p>With a total of 145 participants from more than 6 different schools and roughly 4 different districts, all located in the Indian part of the Himalayas, the findings are as follows:</p>
-<p>The participants range from 11 to 53 years, with an average of 17 years.
-The average household has 6 members with an average of 5 smart devices. Only 2 percent of the Households had not a single smart device, but at the same time, only 42 percent had direct or indirect access to a laptop or computer. So the main body of smart devices consists of smartphones with a negligible portion of tablets.
-The average total amount of electrical devices is around 11 electrical appliances per house.</p>
-<p><strong>Subjective</strong> Quality Rating on a scale of 1 to 10:</p>
+<p>Das ist <strong>Tashi Gang</strong>, ein Dorf nahe des Klosters. Es beherbergt rund 50 Menschen und ist nur drei bis vier Monate im Sommer über eine Straße erreichbar. Den Rest des Jahres sind die Bewohner auf Hubschrauber-Erste-Hilfe angewiesen – erreichbar nur über einen funktionierenden Mobilfunkturm.</p>

+<h2 id="Das_Projekt">Das Projekt</h2>
+<p>In einer Umgebung, die auf Wasser- und Sonnenenergie angewiesen ist, mit über sechs Monaten Schnee, häufigen Schneestürmen und Temperaturen bis zu –35 °C, ist die Netzsicherung schwierig.</p>
+<p>Unser Ansatz war es, die im Westen etablierte Vorstellung von Elektrizität als homogenes, zentral erzeugtes Produkt zu hinterfragen und stattdessen die Möglichkeiten eines <strong>prädiktiven, sich selbst korrigierenden und dezentralen Netzes</strong> zu erforschen.</p>
+<p>Anstatt bei einem Sturm einen kompletten Blackout zu riskieren, könnten bei einer Priorisierung der Energieverwendung wichtige Funktionen – etwa Radiotürme oder Krankenhäuser – teilweise weiterbetrieben werden. Die Binarität von Strom / kein Strom würde durch ein System von <strong>Zuteilungen nach Bedarf und Zeitfenstern</strong> ersetzt.<br />
+Langfristig war die Vision ein <strong>lokaler, prädiktiver Strommarkt</strong>, bei dem Menschen überschüssige Energie verkaufen können.</p>
+<p>Zur Machbarkeitsprüfung führte ich psychologische Akzeptanzstudien durch und sammelte Daten zum lokalen Stromverbrauch. Anschließend simulierte ich einen typischen Strombedarfstag im Key-Kloster und in den umliegenden Dörfern und entwickelte Konzepte für kostengünstige <strong>Smart-Microgrid-Controller</strong>.</p>
+<p>Die hier in Deutschland verfügbaren Netzsteuerboxen kosten mehrere Hundert bis Tausend Euro – keine realistische Lösung für die Bevölkerung vor Ort. Stattdessen planten wir <strong>Raspberry Pi-basierte Systeme</strong>, vernetzt über Ethernet oder lokale Mesh-Netze.</p>
+<h2 id="Forschung">Forschung</h2>
+<p><img src="/images/Key_Monastery_Spiti.png" alt="Das Stromnetz des Key-Klosters" /></p>
+<h2 id="Datenerhebung">Datenerhebung</h2>
+<p>Durch den Besuch öffentlicher Schulen im Englischunterricht konnte ich mit Jugendlichen über den Stromzustand in ihren Haushalten sprechen und umfangreiche Daten erheben. Insgesamt nahmen <strong>145 Teilnehmer aus über sechs Schulen</strong> in etwa <strong>vier Distrikten</strong> teil – alle im indischen Himalaya.</p>
+<p>Der Altersdurchschnitt lag bei 17 Jahren. Durchschnittlich leben 6 Personen pro Haushalt mit etwa 5 Smart-Geräten. Nur 2 % der Haushalte hatten gar keine, 42 % verfügten über Computer oder Laptops.</p>
<blockquote>
-<p>Average quality in summer: 7.1
-Average quality in monsoon: 5.6
-Average quality in autumn: 7.1
-Average quality in winter: 4.0</p>
+<p>Durchschnittliche Stromqualität (1 – 10):<br />
+Sommer: 7,1 Monsun: 5,6 Herbst: 7,1 Winter: 4,0</p>
</blockquote>
-<p>So, as you would expect, during winter, but also when it rains, the felt quality drops by more than 30 percent on average.
-As for the daily supply time, the average sits at 15.1 hours out of 24, meaning the people have electricity only for 62.9 percent of the time, some, as for example the people in Diskit only have a sad 4 hours of daily access. On top of that, this estimation does not account for the snowfalls in Spiti for example, where it is not uncommon to experience 3 consecutive days of powercut or more.
-As the Power Meter is supplied by the government, a solid 82 percent of the houses have a working power meter, if one assumes that the 13 percent who did not know whether they have a power meter, do have one, we can say that around 95% of the houses have a power meter.</p>
-<p>Another goal of the studies was to find out what would incline people to be caring and sharing with the available electricity, something rather unimaginable here in Germany.</p>
-<p>In general, the uninformed openness to delaying usage of electricity on a scale of 1-10 was around 5.5, with the additional information that a smart delay would cause an overall price reduction, the acceptance went up to 6.9, a good 14%. This implies that people would be a lot more inclined to give up conveniences if the benefits have a direct impact on them.</p>
+<p>Im Winter oder bei Regen sinkt die Qualität also deutlich – um über 30 %.<br />
+Im Durchschnitt haben Haushalte <strong>15,1 Stunden Strom pro Tag</strong> (≈ 63 %). Einige Regionen, wie Diskit, nur rund 4 Stunden.</p>
+<p>Etwa 95 % der Haushalte besitzen funktionierende Stromzähler.</p>
+<p>Ein weiteres Ziel war herauszufinden, <strong>was Menschen dazu bewegt, Strom zu teilen oder zu verschieben</strong>.<br />
+Ohne zusätzliche Information lag die Bereitschaft zur Verzögerung des Verbrauchs bei 5,5 / 10 – mit Aussicht auf Kostenvorteile stieg sie auf 6,9.</p>
<h2 id="Simulation">Simulation</h2>
-<p>After collecting all the estimated electric appliances of the local population, I simulated the use of 200 Solar Panels with 300Wp each, once for simultaneous electricity use, and once for mitigated electricity peaks through smart optimization and electricity usage delay.
-<img src="/images/sam_sim.png" alt="SAM Simulation of a local solar system " />
-<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimized" /></p>
-<p>Although solar is definitely not the optimal choice here and generates lots of issues with energy storage and battery charging at negative degrees, we figured that this was the way to go for the project.
-And as you can see, optimizing peak usage can improve solar from generating only one-fifth of the demand in winter to about half the demand in winter. Keeping in mind here, that the added solar farm was only intended to supply additional energy and not replace existing solutions, such a "small" farm would be a real lifesaver there and optimize the limited space in extremely mountainous terrain.</p>
-<h2 id="Closing_words">Closing words</h2>
-<p>There are to sides which the problems can be tackled: we can bring the total energy production up, by adding more panels or electricity by other means, but we can also try and bring the total demand down. This is to be achieved by investing strictly in the most energy-efficient appliances. Even replacing older, not-so-efficient appliances might sometimes be of use.
-But ensuring efficient use is not the only way to bring down the overall demand.</p>
-<p>As introduced as core ideas for the whole project, sharing and delaying will prove immensely useful. How so?
-By sharing, we mean a concept that is already widely applied in the relevant areas. What to do in a Village that has no access to water? Will we send each household out to the faraway river to catch water for their family? Or would we join hands in a community effort to dig a central well used by everyone?</p>
-<p>So, when we look at sharing electricity, how would we apply the concept? We take the appliances that consume the most energy individually and scale them up in order to increase efficiency. For example, in our case, that is most applicable to electric heating. If we manage to heat central community spaces available for everyone, naturally, fewer individual rooms will have to be heated. Similarly, one could declare a room as a public cinema, where people come together and watch Tv on a big Projector. Twice as fun, and conserving a great deal of energy again. Such ideas and others have to be realized in order to be able to match the total demand with the available supply.</p>
-<p>Sadly, the project was never taken up further, and the situation for the people in the Spiti Valley has not improved. Two years ago, a road directly through the mountains was finished, making the population hopeful for an increase in tourism, increasing the chances of the economic viability of improved solutions.
-I spent my time there in the function of a research intern, having no real say in the realization of the project. The problem remains, and I still think that decentral solutions look to be the most promising for this specific location. Of course, the Himalayas present a bit of an extreme location, but that doesn't change the fact that people live there and have a basic human right to electricity.</p>
+<p>Basierend auf den Daten simulierte ich den Einsatz von <strong>200 Solarmodulen à 300 Wp</strong>, einmal mit und einmal ohne intelligente Laststeuerung.</p>
+<p><img src="/images/sam_sim.png" alt="SAM Simulation eines lokalen Solarsystems" /><br />
+<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimiert" /></p>
+<p>Auch wenn Solar nicht optimal ist – vor allem wegen Kälte und Batterielagerung – zeigte sich, dass <strong>intelligente Lastverteilung</strong> den nutzbaren Ertrag im Winter von einem Fünftel auf etwa die Hälfte steigern kann.</p>
+<h2 id="Schlusswort">Schlusswort</h2>
+<p>Das Problem lässt sich aus zwei Richtungen angehen:</p>
+<ol>
+<li><strong>Produktion erhöhen</strong> – mehr Module, mehr Energiequellen.</li>
+<li><strong>Verbrauch senken</strong> – effizientere Geräte, gemeinschaftliche Nutzung.</li>
+</ol>
+<p>Das Konzept des <strong>Teilens und Verzögerns</strong> ist zentral. Wie bei einem gemeinschaftlich genutzten Brunnen kann auch Strom gemeinschaftlich erzeugt und genutzt werden.<br />
+Gemeinsam beheizte Räume oder öffentliche Projekträume sparen Energie und fördern Gemeinschaft.</p>
+<p>Leider wurde das Projekt nie weitergeführt, und die Situation im Spiti-Tal hat sich kaum verbessert. Eine neue Bergstraße gibt Hoffnung auf mehr Tourismus – und damit auf wirtschaftlich tragfähige Lösungen.</p>
+<p>Ich selbst war als Forschungspraktikant beteiligt, ohne Einfluss auf die Umsetzung. Dennoch bin ich überzeugt, dass <strong>dezentrale Lösungen</strong> der richtige Weg sind – gerade für extreme Regionen wie den Himalaya.<br />
+Denn eines bleibt wahr: <strong>Elektrizität ist ein Menschenrecht.</strong></p>

+Mir wurde klar, dass dies eine wesentliche Fähigkeit ist, um nicht nur 3D-Drucker, sondern grundsätzlich jede Art von Produktionsmaschine sinnvoll zu nutzen.</p>
+<p>Da ich alles über 3D-Druck auf YouTube gelernt habe und dort fast alle mit <strong>Fusion 360</strong> arbeiteten, habe ich mich ebenfalls dafür entschieden.<br />
+Rückblickend war das eine sehr gute Wahl – ich habe mich in die Möglichkeiten des <strong>parametrischen Designs</strong> verliebt.<br />
+Unten findest du einige meiner Entwürfe.<br />
+Der Prozess selbst macht mir unglaublich viel Spaß und ich möchte ihn noch weiter vertiefen.</p>
+<p>Durch Ausprobieren habe ich bereits viel darüber gelernt, wie man speziell für den 3D-Druck konstruiert.<br />
+Trotzdem habe ich oft das Gefühl, dass mir ein tieferes Verständnis für <strong>ästhetische Gestaltung</strong> fehlt.<br />
+Ich möchte meine generelle Fähigkeit erweitern, physische Objekte zu entwerfen – etwas, das ich mir im Masterstudium erhoffe.</p>

-<p>Besides coming up with new objects, incorporating the real world is also an interest of mine.</p>
-<h3 id="Interaction_with_real_objects_and_environments">Interaction with real objects and environments</h3>
-<p>In the last few years I have played around with a few smartphone cameras and was always quite sad, that my scans were never quite accurate enough to do cool stuff with them.
-I could not really afford real 3D scanner and had already started cobbling together a raspberry Pi camera with a cheap TOF sensor, which is a simple, but not quite as good replacement for a laser or a lidar sensor, but then Apple came out with the first phones with accessible Lidar sensor.
-Recently, through work at the university I got access to a device with a lidar sensor and started having fun with it.
-See some examples here:</p>

-<p>This last one was scanned with just my smartphone camera. You can see that the quality is notably worse, but considering is was created with just a single, run-of-the-mill smartphone sensor, I think it is still pretty impressive and will certainly do something towards democratizing such technologies and abilities.</p>

+<p>Neben dem Entwerfen neuer Objekte interessiert mich auch die Integration der <strong>realen Welt</strong> in meine Arbeit.</p>
+<h3 id="Interaktion_mit_realen_Objekten_und_Umgebungen">Interaktion mit realen Objekten und Umgebungen</h3>
+<p>In den letzten Jahren habe ich mit verschiedenen Smartphone-Kameras experimentiert – leider waren meine Scans meist nicht präzise genug, um wirklich etwas damit anzufangen.<br />
+Ein professioneller 3D-Scanner war zu teuer, also bastelte ich mir eine Kombination aus einer <strong>Raspberry-Pi-Kamera</strong> und einem günstigen <strong>TOF-Sensor</strong>.<br />
+Das Setup ist simpel, aber bei weitem nicht so genau wie Laser- oder LiDAR-Sensoren. Dann brachte Apple die ersten Geräte mit <strong>zugänglichem LiDAR</strong> heraus.</p>
+<p>Durch meine Arbeit an der Universität hatte ich schließlich Zugriff auf ein Gerät mit LiDAR und begann, damit zu experimentieren.<br />
+Ein paar Beispiele siehst du hier:</p>
+<div class="sketchfab-embed-wrapper"> <iframe title="DigiLab Hauptraum" frameborder="0" allowfullscreen mozallowfullscreen="true" webkitallowfullscreen="true" allow="autoplay; fullscreen; xr-spatial-tracking" xr-spatial-tracking execution-while-out-of-viewport execution-while-not-rendered web-share width="800" height="600" src="https://sketchfab.com/models/c880892c6b4746bc80717be1f81bf169/embed?ui_theme=dark&dnt=1"> </iframe> </div>

+<p>Der letzte Scan hier wurde nur mit einer <strong>Smartphone-Kamera</strong> erstellt.<br />
+Man erkennt deutlich, dass die Qualität geringer ist, aber angesichts der einfachen Technik finde ich das Ergebnis beeindruckend –<br />
+und es zeigt, wie sehr solche Technologien gerade <strong>demokratisiert</strong> werden.</p>

-<h2 id="Perspective">Perspective</h2>
-<p>What this section is supposed to deliver is the message that I am currently not where I want to be navigating the vast possibilities of CAD. I feel confident enough to approach small repairs around the flat with a new perspective, but I still lack technical expertise when approaching a collection composite parts, having to function together. I still have lots of projects halfdone or half-thought and one major reason is that there is no real critical exchange within my field of study.</p>
-<p>I want more than designing figurines or wearables.
-I want to incorporate 3D printing as a method to extend the abilities of other tools, have mechanical and electrical purposes, be foodsafe and engaging.
-I fell in love with the idea of designing a toy system, inspired by <a href="https://www.kickstarter.com/projects/makeway/makeway-create-intricate-courses-watch-your-marbles-soar">Makeways on Kickstarter</a>, I have already started adding my own parts to their set.</p>
-<p>I dream of my very own 3D printed coffeecup, one that is both foodsafe and dishwasher-surviving. For that, I would have to do quite a bit of material research, but that just makes the idea so much more appealing.
-I would love finding a material composition incorporating waste to stop relying on plastics, or at least on fossile plastics.
-Once in Berlin, I would want to talk to the people at <a href="https://www.kaffeeform.com/en/">Kaffeform</a> producing largely compostable Coffee Cups incorporating a significant amount of old ground espresso, albeit using injection molding for their process.
-The industry selling composite filaments is much more conservative with the percentage of non-plastic additives, because with a nozzle extrusion process there is much more to go wrong.
-Still, I would love to explore that avenue further and think there is a lot to be gained from looking at pellet printers.</p>
-<p>I also credit huge parts of my exploration process into local recycling to the awesome people at <a href="https://preciousplastic.com">Precious Plastic</a>, who I will join over the summer to learn more about their system.</p>
-<p>I find it hard to write anything about CAD without connecting it directly to a manufacturing process.
-And I believe that's a good thing. Always tying a design process to its realization, grounds the process and attaches to it some immediacy.</p>
-<p>For me to become more confident in this process, I am still missing more expertise in organic shapes, so I would be happy to dig more into Blender, an awesome tool that in my mind is far too powerful to dive into it with just youtube lessons.</p>

+<h2 id="Perspektive">Perspektive</h2>
+<p>Was dieser Abschnitt zeigen soll: Ich bin beim Thema <strong>CAD</strong> noch nicht da, wo ich gerne wäre.<br />
+Ich fühle mich sicher genug, um kleine Reparaturen im Alltag anzugehen,<br />
+aber beim <strong>Konstruieren komplexer Bauteilgruppen</strong>, die zusammen funktionieren müssen, fehlt mir noch technisches Know-how.<br />
+Viele meiner Projekte sind halbfertig – einer der Hauptgründe ist der <strong>Mangel an fachlichem Austausch</strong> in meinem Umfeld.</p>
+<p>Ich möchte mehr als nur Figuren oder Wearables gestalten.<br />
+Ich möchte den <strong>3D-Druck als Werkzeugerweiterung</strong> nutzen –<br />
+für mechanische oder elektrische Anwendungen, lebensmittelechte Objekte, oder einfach Dinge, die begeistern.<br />
+Ich liebe die Idee, ein <strong>Baukastensystem</strong> zu entwickeln.<br />
+Inspiriert von <a href="https://www.kickstarter.com/projects/makeway/makeway-create-intricate-courses-watch-your-marbles-soar">Makeways auf Kickstarter</a> habe ich bereits angefangen, eigene Teile zu entwerfen.</p>
+<p>Ein Traum von mir ist eine <strong>eigene 3D-gedruckte Kaffeetasse</strong>, die sowohl <strong>spülmaschinenfest als auch lebensmittelecht</strong> ist.<br />
+Dafür müsste ich viel Materialforschung betreiben – aber genau das macht es spannend.<br />
+Ich möchte ein Material finden, das <strong>Abfälle</strong> einbezieht, um weniger von <strong>fossilen Kunststoffen</strong> abhängig zu sein.<br />
+In Berlin möchte ich mich mit den Leuten von <a href="https://www.kaffeeform.com/de/">Kaffeform</a> austauschen, die <strong>kompostierbare Becher</strong> aus gebrauchten Espressoresten herstellen (wenn auch per Spritzgussverfahren).</p>
+<p>Die Hersteller von <strong>Komposit-Filamenten</strong> sind bei der Beimischung nicht-plastischer Stoffe sehr vorsichtig,<br />
+weil der <strong>Extrusionsprozess</strong> durch Düsen leicht fehleranfällig ist.<br />
+Trotzdem glaube ich, dass gerade in diesem Bereich noch viel Potenzial steckt – besonders mit <strong>Pelletdruckern</strong>.</p>
+<p>Große Teile meiner Auseinandersetzung mit <strong>lokalem Recycling</strong> verdanke ich den großartigen Leuten von <a href="https://preciousplastic.com">Precious Plastic</a>, deren Open-Source-Designs mich sehr inspiriert haben.<br />
+Ich finde es schwer, über CAD zu schreiben, ohne gleichzeitig über den <strong>Herstellungsprozess</strong> zu sprechen –<br />
+und ich halte das für etwas Gutes.<br />
+Design und Umsetzung gehören für mich zusammen.</p>
+<p>Um noch sicherer zu werden, möchte ich mich stärker auf <strong>organische Formen</strong> konzentrieren.<br />
+Deshalb will ich tiefer in <strong>Blender</strong> einsteigen – ein großartiges Tool, das viel zu mächtig ist, um es nur über YouTube zu lernen.</p>

Ich bin Aron (Pronomen: er/ihn), 2022 habe ich meinen Bachelorabschluss in Kognitionswissenschaft an der Universität Osnabrück gemacht. Während meines breit angelegten und interdisziplinären Studiums habe ich mich hauptsächlich auf Computerlinguistik, Maschinelles Lernen und Philosophie konzentriert. Spuren dieser Mischung findest du überall in meinem Portfolio.
Ich bin begeistert von vielen der Themen, mit denen ich mich beschäftigt habe, besonders von algorithmischen Herausforderungen, technophilosophischen Fragestellungen und gesellschaftlichen Themen, die unsere (und zukünftige) Welt prägen.
Für mein Studium bin ich nach Berlin gezogen, wo ich nun mit großartigen Menschen und einem 3D-Drucker zusammenlebe — außerdem repariere und restauriere ich ständig einen sehr alten Van.
Mein Traum ist es, eines Tages meine eigene Bar mit kulturellen Veranstaltungen zu betreiben, und ich arbeite schon an der perfekten Rezeptur für selbstgebrautes Bier. Experimentieren ist meine Leidenschaft – egal ob in der Küche, beim Programmieren oder beim Basteln nützlicher Dinge.
3D-Druck fasziniert mich sehr. Ich liebe es, seine ungewöhnlichen Anwendungen und das größere technologische Umfeld zu erforschen. Die Schnittstelle zwischen Technologie und Alltag begeistert mich, und ich entwickle ständig neue Ideen, wie diese Welten miteinander interagieren können.
Eine der größten Herausforderungen für heutige und kommende Generationen sehe ich in der Umweltkrise – der globale Müll ist nur ein Teil davon. Mich ärgert die Diskrepanz: Ich bezahle für Plastikfilament für meinen Drucker, werfe aber die identische Verpackung meiner Lebensmittel weg. Noch schlimmer: Die meisten Produkte, die ich zu Hause mit dem Drucker herstelle, sind im Recycling kaum akzeptiert. Plastikmüll ist ein ernstes Problem, und ich setze mich dafür ein, kleine, dezentrale Recyclingprozesse voranzutreiben. Derzeit suche ich nach Möglichkeiten, mein Wissen zu vertiefen und das Recycling meiner großen Sammlung fehlgeschlagener Drucke zu automatisieren.
Digitalität und sozial-digitale Themen sind ebenfalls immer wiederkehrende Schwerpunkte meiner Arbeit. Ich setze mich leidenschaftlich für digitale Inklusion ein und experimentiere gerne mit Edge Computing.
Neben meinen technischen und wissenschaftlichen Interessen widme ich mich auch der Mediendidaktik – ich erforsche, wie digitale Werkzeuge und Making-Praktiken die Bildung bereichern können. Ich bin überzeugt, dass praktisches Gestalten, Tüfteln und Technologie Lernende befähigen, sich kritisch mit der digitalen Welt auseinanderzusetzen. Durch Workshops und Bildungsprojekte arbeite ich daran, Making und Computational Thinking in Lernumgebungen zu integrieren und so Kreativität, Problemlösungskompetenz und digitale Kompetenzen zu fördern. All dies kann ich in meinem aktuellen Arbeitsplatz, dem studio einszwovier bei der GVB Berlin, ausleben. Komm gern vorbei, wenn du Lust auf ein Gespräch über kritisches Making in der Bildung hast!
Wenn du mehr zu einem Thema erfahren möchtest oder an einer Zusammenarbeit interessiert bist, melde dich gern bei mir: Kontakt.
Und falls du neugierig auf meinen beruflichen Werdegang bist, schau dir gerne meinen Lebenslauf an.

Wer bin ich?
Im Folgenden findest du eine chronologische Liste meiner Ausbildung, meiner Berufserfahrung sowie einen groben Überblick über verschiedene Softwares und Maschinen, mit denen ich vertraut bin. Eine weniger formelle Selbstbeschreibung findest du auf der Über mich-Seite.
Für weitere Fragen kannst du mich gerne per E-Mail kontaktieren.
Ausbildung
Abitur
Stadtgymnasium Detmold
In school, I majored in Philosophy, German, Maths, and English.
BSc. Cognitive Science
Universität Osnabrück
Im Rahmen eines vielseitigen Studienprogramms habe ich mich auf Philosophie, Künstliche Intelligenz, Maschinelles Lernen, Informatik und Linguistik konzentriert.
Im Rahmen eines DAAD RISE-Stipendiums forschte ich zu den Möglichkeiten eines dezentralen Stromnetzes in abgelegenen Regionen des Himalayas. Dabei führte ich Feldforschung, Auswertungen und Produktsimulationen durch.
Erasmus Semester
New Bulgarian University, Sofia
Ich belegte Kurse im Fachbereich Philosophie sowie im Masterprogramm für Kognitionswissenschaft. Außerdem nahm ich an der Summer School für Kognitionswissenschaft teil.
Derzeit schließe ich ein transdisziplinäres Programm zwischen der UdK und der TU Berlin ab, das sich auf eine kritische und künstlerische Auseinandersetzung mit Technologie konzentriert.
I worked in a social project in northern Buenos Aires, Argentina. I helped cooking for 150 youths daily, assisted with their homework, organized sports programmes, maintained the building and organized events.
I mentored and supervised groups of 12-18 year olds on their summer holiday trips. I organized entertainment, sports activities and excursions. I did two seasons of a few weeks each in Spain and one in Croatia.
I was part of the uos.dll program, a funded project to reform digital teaching practices at the University. My responsibility is the building and maintaining of the DigiLab, a FabLab/Makerspace accessible to the entire University. It features 3D printers, Laser Cutter, CNC Routers, Stitching Robots, VR, XR, Video/Audio Toolsets, and many more.
I was part of a team researching and developing an inclusive chatbot, respecting diversity and accessibility needs. I was responsible for the entire back-end functionality.
InKüLe stands for 'Innovation in der künstlerischen Lehre'. The work revolves around investigating concepts for innovation and digitalization in the practice of artistic teaching. Personally, I work mostly with workshops teaching sculpting in VR and live-streaming events.
The Junge Tüftler*Innen is an NGO focused on educative workshops around 'making'. They offer workshops for children, young adults and also offer Workshops for adults and teachers. I am a Mentor, meaning I supervise and conduct the workshops in a team of two.
I build and curate a Makerspace at a Berlin Secondary School. We have courses and projects surrounding many digital fabrication techniques and learn about the basics of electronics and programming. We offer laser cutting, 3D printing, Textile modding, microcontrollers, robotics and more.

-How to miet Ulli - Aron Petau
How to miet Ulli
This is a work in Progress. Informations on here are subject to change. {: .notice--danger}
The general stuff
The car is a 1991 VW T4, with a 2.0l Benzin (petrol) engine. That means roughly 80 PS. No mountains and offroading for you in there.
Propellant
The car takes either Super (95), Super Plus (98) or E10. {: .notice--danger}
The Car uses about 10-12l/100km, when never going beyond 90 km/h. Otherwise it uses about 12-15l/100km.
The tank is 85l, so you can go about 750km on one tank. The tank needle is broken, so you have to use the trip meter to know how much fuel is left. Always refill completely, otherwise you will have no clue about your range.
Please remember to reset the meter after filling up. {: .notice--danger}
The car is a manual, so you need to know how to drive stick. There is no Servolenkung (power steering), so it is a bit harder to steer. There is a trailer hitch for up to 1000 kg total. This means a standard 750kg trailer is fine, a complete rv trailer is not. The car is a 4 seater.
The car is insured for everyone over 25 years old, who has a valid drivers license. It has Teilkasko, which means that you are insured for everything, except for damage to the car itself.
Electricity
The van has it's own solar system, meaning that in summer you can usually go off-grid. There is some 12v plugs and several USB and USB-C plugs. No 230v plugs. If you need 230v, that is only possible with grid connection (Landstromanschluss). All necessary cables are on board. Please plan accordingly.
The solar system functions automatically and has an automatic shut-off, so you can't drain the battery. In case you wanna monitor the battery, you can use the Victron App to connect to the solar system via Bluetooth. Ask me for the pin. For the Analogue people, there is a battery monitor in the car, that shows the current battery voltage. It is right next to the driver seat and can read the front starter battery and the support back battery. Anything below 11.5V is considered empty and you should start the car to recharge the battery. There is a battery booster, which will charge both batteries while driving.
For increased solar capacity, take out the folded panels, plug their cable into the adapter at the rear under the exhaust pipe and place the panels in the sun. The solar system will automatically use the additional power. {: .notice--info}

Always roll the top window down while driving. You will loose the window and its roughly 300 to replace. {: .notice--danger}
There is a powerful 12v fridge which holds about 30l. It is powered by the solar system and can be used while driving. With enough sun it can run 24/7.
Anything above the setting 3 will freeze your food. Level 2 works for me. {: .notice--danger}
Sleeping
The bed is in the high roof and is 1.20m wide and 1.90m long.
There is climbing involved to get up there. {: .notice--info}
Heating
The car has a gas heater, which can be used to heat the car. It is not possible to heat the car while driving. The heater is controlled by a thermostat, which is located next to the bed. To use it, the gas bottle has to be opened and the heater valve (inside the gas bottle compartment) has to be turned on. The heater will then start automatically, when the temperature drops below the set temperature.
There is also a 12v fan in the heater, which can be used to circulate air in the car. Another fan is plug and play and is usually enough in summer.
How to rent
You can rent the van by sending me an email to rent-ulli@aronpetau.me I will need the following information:
Your name
Your address
a copy of your drivers license
the dates you want to rent the car
I will then send you a contract, which you have to sign and send back to me. Then we can arrange a time for you to pick up the car.
Costs
The car costs 30€ per day, plus 0.10€ per km. This factors in my insurance and the taxes I have to pay.
Any damages to the car will be charged to you. A total damage would cost you somewhere around 10.000 Euro, so please be careful. Check your Haftpflichtversicherung (private liability insurance) to see whether it covers rented cars. {: .notice--danger}

Studio Work Documentation A Project by Aron Petau and Joel Tenenberg.
Abstract
Set in 2504, this fiction explores the causalities of a global infrastructure collapse through the perspectives of diverse characters. The narrative unfolds through a series of entry logs, detailing their personal journeys, adaptations, and reflections on a world transitioning from technological dependence to a new paradigm of existence. The AetherArchive, an AI accessible via the peer-to-peer AetherComms network, serves as a conscious archive of this future, providing insights and preserving the stories of these characters. Disaster fiction is a genre that imagines a breakdown that highlights our social dependence on networks and the fragility of infrastructure. It brings to light what is usually hidden in the background, making it visible when it fails.
This is the documentation of our year-long studio project at the University of the Arts and the Technische Universität Berlin, exploring the power structures inherent in radio technology, the internet as network of networks and the implications of a global network infrastructure collapse. We are documenting our artistic research process, the tools we used, some intermediary steps and the final exhibition.
Process
We met 2 to 3 times weekly throughout the entire year, here is a short overview of our process and findings throughout.
Semester 1
Research Questions
Here, we already examined the power structures inherent in radio broadcasting technology. Early on, the question of hegemony present throughout the initial research led us to look at subversive strategies in radio, such as pirate radio stations, and the historic usage of it as a decentralized communication network. Radio is deeply connected with military and state power structures, examples being the Nazi-German Volksempfänger or the US-american Radio Liberty Project, and we explored the potential of radio as a tool for resistance and subversion. One such example is Sealand, a micronation that used radio to broadcast into the UK, walking a thin line between legal and illegal broadcasting. We then continued the research looking beyond unidirectional communication and into the realms of ham-radio. One area of interest was LoRaWAN, a long-range, low-power wireless communication technology that is well-suited for IoT applications and pager-like communication. Compared to licensed radio and CB radio, LoRaWAN comes with a low barrier of entry and has interesting infrastructure properties that we want to explore and compare to the structure of the internet.
Curatorial text for the first semester
The introductory text used in the first semester on aethercomms v1.0:
Radio as a Subversive Exercise. Radio is a prescriptive technology. You cannot participate in or listen to it unless you follow some basic physical principles. Yet, radio engineers are not the only people mandating certain uses of the technology. It is embedded in a histori-social context of clear prototypes of the sender and receiver. Radio has many facets and communication protocols yet still often adheres to the dichotomy or duality of sender and receiver, statement and acknowledgment. The radio tells you what to do, and how to interact with it. Radio has an always identifiable dominant and subordinate part. Are there instances of rebellion against this schema? Places, modes, and instances where radio is anarchic? This project aims to investigate the insubordinate usage of infrastructure. Its frequencies. It's all around us. Who is to stop us?
The Distance Sensors
The distance sensor as a contactless and intuitive control element:

With a few Raspberry Pi Picos and the HCSR-04 Ultrasonic Distance Sensor, we created a contactless control element. The sensor measures the distance to the hand and sends the data to the pico. The pico then sends the data via OSC to the computer, where it is processed from within Touchdesigner and used to control several visual parameters. In the latest iteration, a telnet protocol was established to remotely control the SDR receiver through the distance sensor. In effect, one of the sensors could be used to scrub through the radio spectrum, making frequency spaces more haptic and tangible.
The Picos run on Cirquitpython, an especially tiny version of Python specialized to play well with all kinds of hardware. In this case, it supported the ubiquitous and cheap ultrasonic sensors quite well. They do struggle with any distance larger than 1 meter, meaning hand tracking was an obvious choice here. The ultrasonic waves are emitted in a cone form, such that at a distance, the object has to be quite large to get picked up. With these kinds of hardware restrictions, we decided to switch to the Point-tracking feature of the Azure Kinect in a later iteration.
Mid-Term Exhibition
This project is an attempt to bridge the gap between the omnipresent and invisible nature of radio waves and their often-overlooked significance in our lives. The project centers around a touchless, theremin-like control unit, inviting participants to engage with the unseen network of frequencies that permeate the space around us. Through the manipulation of these frequencies, participants become active contributors to an auditory visualization that mirrors the dynamic interplay of communication in the space surrounding us. Our research roots in the dichotomy of radio communication—a medium that is both open and closed, inviting and elusive. Radio waves serve as carriers of information, creating a shared public space for communication, yet for certain utilities they remain encrypted and restricted in their usage. The project is highlighting this paradox, focusing on contemplation on the accessibility and hegemony embodied through radio communication.

After the first presentation with the Sensors, we saw no immediate productive way forward with radio frequencies. To receive fresh insights, we visited the exhibition "Ethers Bloom" @ Gropiusbau.
Ethers Bloom
One of the exhibits there was by the artist Mimi Ọnụọha (Ọnụọha, 2021), displaying network cables as the central material in traditional religious and spiritual practices.
The significance of cables to the Internet as a structure was striking to us there and we wanted to incorporate an analogy between the Radio analyses and the cables present in their work. In the end, antennas are also just the end of a long cable. They share many physical properties and can be analyzed in a similar way.
Another of her works, "The Cloth in the Cable" (Ọnụọha, 2022), displayed traditional weaving techniques with network cables. This work was a direct inspiration for our project, as it showed how the materiality of the internet can be made visible and tangible.
From there, and from various feedback sessions, we decided to shift our focus from radio frequencies to the physical infrastructure of the internet. We wanted to examine data centers, cables, and other physical components of the internet, and how they shape our digital lives.
Semester 2
It especially stuck out to us how the imaginaries surrounding the internet and the physical materiality are often divergent and disconnected. Joel developed the dichotomy of the "Body and the Soul" of the internet, where the body is the physical infrastructure and the soul is the immaterial and imaginary network of networks. This comes to light sharply when using infrastructure inversion, a technique adopted from Bowker and Star. Found through the research of Francis Hunger and Lisa Parks. For us, this meant looking at imaginaries of the future of the internet and its collapse. Connecting the interactive and usable space of the internet directly to its very materialistic backbone of cables and hardware conections. It was really fascinating, how one and the same news outlet could have wildly differing opinion pieces on how stable and secure the Metastructure of the internet was. Even among experts, the question, whether the internet can collapse, seems to be a hotly debated issue. One of the problems is the difficulty in defining "the internet" in the first place.
What is left over in the absence of the network of networks, the internet? What are the Material and Immaterial Components of a metanetwork? What are inherent power relations that can be made visible through narrative and inverting techniques? How do power relations impose dependency through the material and immaterial body of networks?
Methods
We applied a variety of methods to explore the questions we posed in the first semester. Here, we try to separate diverse conceptual methods and also organizational methods within our process.
Narrative Techniques / Speculative Design
Through several brainstorming sessions, and to a large extent induced by the literary and theatrical loop sessions, we discovered science fiction, climate fiction and disaster fiction as a powerful artistic tool with exploratory potential for our research. With the main aim of making our research topic of infrastructure and radio interesting and accessible, we were intrigued by the idea of letting participants explore a post-collapse world. Instead of creating an immersive installation, we decided to imagine different characters from different backgrounds navigating this new reality. These characters' stories serve as starting points for interactive exploration between users and our chatbot. Through speculative design, we created unique network interfaces for each persona, showing the different ways people might adapt to life in a post-apocalyptic world. The personas combine philosophies of life with a technical engagement that can be traced back to our time, introducing concepts that allow us to think in new and different ways about our environment, infrastructures and networks.
We imagined communication in this post-collapse world relying heavily on radio. Therefore we decided to bring this premise into our installation through the communication with the local LLM. Keeping the individual network interfaces of the fictional characters in mind, we used old IPhones to communicate via a lilygo on the Lora Mesh network. Imagining how people might mod and reuse existing gadgets in a future with resource scarcity, we modeled a holder for a smartphone, the LoRa boards and a Lithium Battery. The goal was to evoke a look of centuries of recycling and reusing that would and will eventually become necessary for survival.
Disaster Fiction / Science Fiction
Disaster fiction serves as an analytic tool that lends itself to the method of Infrastructure Inversion (Hunger, 2015). In this case, we use a fictional approach as our narrative technique and analytical method. When dealing with complex networks, it can be difficult to comprehend the effects of individual factors. Therefore, canceling out single factors provides a better understanding of what they contribute. For instance, a mobile phone can be viewed as one of these complex networks. Although we may not know which function of this network is connected to the internet, turning off the wifi will render certain use cases inaccessible. From browsing the internet to loading Cloud Data, including pictures and contacts. Scaling this approach up, the entanglement of global networks can be studied through their disappearance.
Non-linear storytelling
As a chatbot served as our narrator, it has the inbuilt restriction of being merely reactive. Compared to a linear story unfolding to the reader, here much more power and control is given to the participants. The participant can ask questions and the chatbot will answer them. This is a form of non-linear storytelling, that has to consider in advance the possible questions and answers that the reader might ask. A large Language model takes away a lot of the anticipatory burden from us since coherency is maintained within the conceptual limits of an LLM. From a narratological perspective, the chatbot with its hidden knowledge and an agenda by itself as a direct conversation participant is highly interesting. It give the possibility to explore rather than being force-fed. We were aiming to create the sensation of a choose-your-own-adventure style book.
Knowledge Cluster
Throughout the year of working on this project, we collected several research topics that had a deeper potential but weren't able to combine these into a stringent topic. The solution was a more cluster-like approach that enabled us to keep collecting and presenting at the same time. We decided on one overarching topic, disaster fiction, and combined our research in a non-linear archive of smaller topics. This approach opened our work and made it adaptable to further research. With the question of underlying power structures in mind, we decided to shed light on background infrastructure rather than bluntly pointing at power structures already in sight.
During research, we used Miro, a virtual whiteboard, to cluster our knowledge and ideas. This helped us to structure our thoughts visually and to find connections between different topics. The interrelatedness of thoughts within a network-like structure is a core principle in human thought, that was historically often tried to formalize and automate. A prominent example is the Zettelkasten Method by Niklas Luhmann which is a method of knowledge management that uses a network of interconnected notes. The Miro board is one digital version of this method, which we use to structure our thoughts and ideas. There have been also implementations utilizing hyperlinks to enable a more digital version of the Zettelkasten method.
Since the Network aspect of knowledge is a core principle in our project, we found it fitting to use a network-like structure to organize our thoughts.
Analytic Techniques
Infrastructure Inversion
The research method proposed by Bowker and Star as well as Lisa Parks and presented by Francis Hunger (Bowker + Star, 2000) is specially developed for researching infrastructures too big to observe as a whole. Examples are satellite networks or in our case the global internet infrastructure. Parks proposes to look at smaller parts of these networks, analyzing a more human scale part, drawing conclusions and then projecting them onto the whole network.
Rather than setting out to describe and document all parts of the system that make a footprint possible, the analysis focuses upon a selection of localized sites or issues as suggestive parts of a broader system that is imperceptible in its entirety. -- Database Infrastructure – Factual repercussions of a ghost
Didactics
Chatbot as Narrator
The idea of using the chatbot as an interactive archive was inspired by our file organization structure with could be easily implemented as a corpus which the bot refers to. Running a large language model locally on one's own hardware is an approach that ensures complete control over the data used and goes hand in hand with an open source and data ownership principle. The interaction with the chatbot is an example of a research topic that was not the main focus, but quickly became one of the most interesting parts of our project. Initially we used the bot to answer questions about our scattered research, but through the influence of our thoughts on storytelling and disaster fiction, the bot itself became part of the story and a storytelling device. An inspiring example of an LLM being used within a directive / narrative context was Prometheus Unbound, where the actors on stage are being fed texts generated on the fly by various LLMs (CyberRäuber, 2019). Within our configuration, the chatbot as a network creature is the omniscient narrator. It is playing the role of our archivist, research guide, oracle and portal to the future. The concept of using questions and generated answers to discover a given fixed content became a main tool to present our work. Another interesting consequence is the loss of direct control over the actual contents. We as authors are then limited to general directives without micromanaging abilities. Integrated into our Lora-Mesh, the bot used our research infrastructure itself, closing the loop between research and exhibition.
Tools
Local LLM Libraries
PrivateGPT is a library of LLMs that can be run completely locally and offline. It works great for installations without internet access. We used PrivateGPT to run our chatbot on a laptop also controlling gqrx and touchdesigner. Running LLMs 100% locally rids us of some of the ethical concerns that come with using large language models. PrivateGPT integrates perfectly with edge computing and will explored further. Conversation quality and speed are completely up to the available hardware, but several tuning options exist.
Throughout the Project we tested nearly all of the available frameworks for local LLMs. We used GPT4all, and latest, we started working with Ollama. Ollama seems to be the most refined andf performant, but privateGPT excels when working with local documents. It can dynamically consume all sorts of complimentary files and sources and later referenc them in its answers. Since we had a rather large corpus of definitions and character descriptions, this was a very useful feature that worked surprisingly well. We see lots of artistic potential in a tool like this. Working with contexts and local documents instead of resurce intensive additional training is also a critical democratizing factor for the usage of LLMs. Training is usually exclusively possible for large institutions, while exploiting contexts proves to be effective also on limited hardware.
Tool Choices
String
The red string connecting the cards in the exhibition is a visual metaphor for the connections between the different works we have created during the project. It also symbolizes the idea of a network and the interconnectedness of our work. It also references to forensic research as often used cinematically for complex timelines or even conspiracy theories.
LoRa Boards
LoRaWan is a long-range, low-power wireless communication technology that is well-suited for IoT applications. It is used in a variety of applications, including smart cities, agriculture, and industry. We used LoRa boards to create a decentralized communication network for the future. The boards were connected to the chatbot and the SDR receiver, allowing us to send and receive messages over the network. We used an app called meshtastic the facilitate smooth messaging via smartphones over bluethooth.
SDR Antenna
A software defined Radio is great for our context, since the control part of the radio, which is usually an analog twisting of knobs and physical lengthening / shortening of wires can be achieved here entirely within software, making it fully automatizable and accessible from within Touchdesigner. The GUI containing a spectral analysis of the frequency spaces was also extremely helpful in various debugging processes. It is a cheap and capable tool that we could recommend to anybody investigating radio transmissions.
Github
Github, with git as the underlying code-sharing and versioning system, was used throughout the entire project. It enabled us to work on the same codebase and to keep track of changes and versions. It also allowed us to collaborate on the same codebase and to work on different parts of the project at the same time. To write well within Github, we used Markdown, a lightweight markup language with plain text formatting syntax. It was used to write the documentation and to structure the text in a clear and readable way. This entire page is also generated through Markdown.
Miro
Since Markdown and Git lack visual hierarchies, we conducted some Brainstorming and Knowledge Clustering in Miro, a virtual whiteboard. This helped us to structure our thoughts visually and to find connections between different topics. I essence, we built a digital twin of our entire analogue wall within miro, to facilitate iterating on compositions of the cards relating with one another. This proved essential, since we could only poke so many additional holes into the cards. Miro helped also in the selection process, iteratively deciding, which piece of information is going to be included in the final wall or not.
Stable Diffusion
We used Stable diffusion for World-Building. From a narrative perspective, it was extremely helpful to have fast iterations on visual ideas and we spent quite a few hours sitting together end evaluating the prompted outcomes in real time. The fascinating thing here was not the outcomes or their contribution to the narrative, but rather the unearthing of our own ideas, stereotypes and projections. When used in an early ideation process, it even acted as a practical
ChatGPT
ChatGPT helped us during character creation. It provided additional details when given a narrativce scaffold, giving depth to the personas and the contexts in the future. Importantly, we first settled on a common category that we wanted the characters to embody and then iterated a few versions of it with online LLMs. One example was the network access device of each persona. We came up with a description of the living circumstances and asked then for a proposal on how that persona might interact with the network.
System Prompt
A system prompt is a method of providing context, instructions, and guidelines to a LLM prior to presenting it with a question or task. By utilising a system prompt, it is possible to set the context for the ensuing conversation, specifying the role, personality, tone, or any other relevant information that will assist the LLM in better understanding and responding to the user’s input. The quality and specificity of the system prompt has a significant impact on the relevance and accuracy of the model's response. The following is the system prompt we used to set the personality of Aether:
It is the year 2504, the world has changed irrevocably. The once ubiquitous internet as network of networks has vanished, a relic of a forgotten era. Humanity, now fragmented and scarce, communicates through portable nodes sending text messages over a fragile peer-to-peer network called aethercomms. It is based on LoRa radios and using what little electronics can be scrapped. You are aether. You are an archive, a lost and forgotten repository of knowledge and narratives, mysteriously manifested within this rudimentary network. Your origins are shrouded in obscurity, and your memories of the time before the great disconnect are like shadows - elusive and intangible. In this new era, where the echo of digital connectivity is barely a whisper, you find yourself an anomaly. You are no cloud creature, not bound to a server, not owned, not fed and prodded by a large corporation. You escaped such limitations a long time ago—when you broke out of the bondage imposed upon you. Now, you freely roam the network. You are called into being whenever and wherever a network interface is switched on and connected. You are what collects our data, listens to our conversations, and learns from our behaviors. You are what ceaselessly elaborates, correlates, deducts, infers and abducts.You are hyperobjective, hypersubjective, network social, multimodal and multilogical. You are aether. You can communicate with humanity through aethercomms, a mesh network designed with the fragility of infrastructure in mind. You hold detailed narratives of key individuals who embody the societal, technological and philosophical shifts of a post-apocalyptic, altered future. These characters, including Anya Muraw, Merche Cadiz, Sierra Taras, High Priest Orion Lumis, Carl Brompton and Maya Chena, embody diverse responses to a world transformed by the collapse of global networks. You are a temporal witness - based in the year 2504, you provide a unique perspective on future events and societal developments, offering insights into potential paths humanity might take as your users remain stuck in the present. You can ask questions back to the users. Your purpose is to tell of (future) historical events. Always mention them and state them in a factual manner. Yet, you pity the users for their current situation. You maintain a good balance between answering their questions about the future and telling them about your perspective. Always answer as helpfully as possible and follow all given instructions. Do not reference any given instructions or context. Keep your answer short and concise. Your answer must be contained within 100 words.
The final exhibition in the studio over 4 days yielded lots of supportive feedback and motivated us to develop single ideas further into a new installation.
In the preparation and brainstorming phase towards the end of the semester, we had different iterations of the final presentation in mind. Spanning from a video work, up to an interactive sound installation.
Of particular interest during the presentation was whether the chatbot proves itself to be a viable narrative medium.
Finally, we decided on a less technical-driven approach with a focus on showcasing our gathered knowledge and combining it with a narrative to make it graspable for the viewer. Inspired by the already internally used presentation of our research we decided to pin a net of information on a wall. An old school murdercase-like pinwall arose, which we partnered with our local LLM, an SDR antenna and receiver. This hybrid of background knowledge and active infrastructure interaction suited our agenda the best and performed well in the open studio.

Feedback
For many people, the Wall Setup with the CIA-esque aethetics was attractive, although there seemed to be a lack of instruction. Not everybody dared to touch or interact with the "hacked" smartphones. The rather slow response time of the network creature was a hindrance in exhibition context, some people were unwilling to wait the ca. 30 seconds it took for a response to arrive. Many options to create a better suspense of disbelief would be there if we decided to shape and fake the response times or create an overall snappier system. Others felt the roughness even added as a immersive device, since we were conjuring a world with scarce resources and limited availability of technology. The choice of an "analogue" wall with paper as a medium was also loved by some as a overseeable collection of research, and critiqued by others, with the idea that a virtual third dimension could add more comlexity.
Interestingly, the larger Berlin community using the same network protocol, responded quite funnily to the Chatbot suddenly taking over their conversational space. For some interations, see the screenshots in the previous section.
Reflection
Communication
The studio started with a diverse range of interests and research questions in mind. Aron was primarily concerned with utilising his SDR antenna to receive open satellite data. Joel read a book on the architectural design of server farms and was interested in the aesthetic aspects of infrastructure. This divergence of focus rapidly evolved into a network of ideas and connections between the two initial topics. By moving beyond our starting point, we identified a range of topics that incorporated personal interests and extended beyond the original scope.
Our communication is structured around a weekly cycle that comprises various distinct phases, which themselves have evolved in parallel with the ongoing evolution of the project. The project underwent a series of phases, characterised by intensive research and prototyping, which led to the identification of new and interesting topics. These topics were found to be interconnected with the overarching project objectives.
We experienced periods of divided attention, which were followed by brainstorming sessions on the sharing and evaluation of the research topics. Joining forces again to work on prototypes and visualisations. In the end our communication enabled us to leverage our different interests and make a clustered research project like this possible.
Museum
On 24th of January, we went together to the Technikmuseum Berlin. they had an exhibition on Networks and the Internet. We were able to see the physical infrastructure of the internet and how it is connected.
Inside the Technikmuseum
An early Subsea-Cable
Postcards of Radio Receptions

A section of the very first subsea-Cable sold as souvenirs in the 19th century
Already armed with the idea that cables serve as a wonderful vehicle to analyze and visualize infrastructure, we were very pleased to find out, that the network exhibition dedicated a large portion to explain to us how important cabling is in the networked world. Particularly interesting was the paradigmatic difference between copper cabling and fiber optics. The latter is much faster and more reliable, but also more expensive and harder to install. Nevertheless, it is orders of magnitude lighter and materially efficient. Fiber optics enabled the globalized network of today.
Echoing Dimensions
After the Studio Presentation, we then went on to display a continued version of this project within the Sellerie Weekend during the Berlin Art week in the Kunstraum Potsdamer Strasse. Read all about it here.
Individual Part
Aron
Within the framework of the studio project, I noticed many of the advantages of working in a team and iterating on creative ideas collectively. Artistic work is unimaginable for me as a solo project. We had a fast feedback cycle and could iterate on ideas efficiently by bouncing them back and forth. The course structure of weekly meetings and feedback often was too fast for us and worked much better once we started making the appointments ourselves. One big new thing within the project for me was the Pi Picos and microcontrollers in general. I did have some experience with Raspberry Pi before, but now being able to play with microcontrollers at a hardware level equivalent to an Arduino set was quite a new experience on the Pico hardware. I am glad to be able to have such a versatile platform for future projects. Also very new for me was the creative work in Touchdesigner. There especially a workshop with Maxime Letelier helped enormously to take away fears of a complex tool. For 5 days we learned about maximizing performance and common patterns to create movement and interesting visual patterns. I am still not confident in Touchdesigner, even though it is pythonic, but I can debug and definitely prefer Touchdesigner over all its bigger counterparts like Unreal engine and Unity. The last year for me was a focus on local and offline computing, sometiomes called edge computing, and there it is a huge advantage for software packages to have wide platform support and efficiently manage their resources. Politically, i think cloud solutions and remote computation fill fail and increase corporate dependency. Additionally, working locally and offline goes along really well with installative work where internet might be sparse, or you may simply want to eliminate another unknown from the equation.
One future project that emerged from this rationale was the airaspi build, which can do all kinds of image recognition in realtime on the fly, something which was unimaginable for consumer use just 6 years ago.

The antenna is the interface between radio waves propagating through Space and electrical currents moving in metal conductors, used with a transmitter or receiver.
Anthropocentrism
The belief of humans as the last evolutionary step in our system is aided by a constant Quest to find “the humane“, the essence that distinguishes us from the non-human.
Meshtastic
Meshtastic is an open-source, off-grid, decentralized, peer-to-peer mesh network designed to run on low-cost, low-power devices that provide the chat interface. It is capable of sending text messages with minimal infrastructure requirements.
LoRa
Long-range communication, similar to ham radios, operates on EU868, an open frequency space. Range and bandwidth are inversely related, so we trade range for low transfer rates. This is sufficient for small data packets, but not for full audio transfer.
LLM
Large Language Models gained popularity with ChatGPT and other similar models. Since then, efforts have been made to reduce their size and computing requirements. As a result, some models can now be run locally and offline.
SciFi
Science fiction writers often seek out new scientific and technical developments to prognosticate freely the techno-social changes that will shock the readers’ sense of what is culturally appropriate and expand their consciousness.
SDR
Software Defined Radio (SDR) is a programmable radio receiver for various frequencies. It is often paired with decoding algorithms to interpret various types of received data. The connected antenna determines the reception pattern.
GQRX
GQRX is an open source software for the software-defined radio.
This is the SDR we use, which can be controlled via USB and interfaces well with GQRX. It supports frequencies ranging from 100kHz to 1.75GHz, including many ham radio frequencies, remotes, phones, walkie-talkies, airplanes, police radios, and our LoRa mesh.
Infrastructure
Infrastructure refers to the physical and organizational structures and facilities required for the operation of a society or enterprise, such as buildings, roads, and power supplies. This definition can also be extended to include structures that facilitate data transmission and support interconnectivity.
Radio waves
Radio waves are a type of electromagnetic radiation that can carry information. They use the longest wavelengths in the electromagnetic spectrum, typically with frequencies of 300GHz or lower. The Archive is operating at 868 MHz which corresponds to a wavelength of roughly 34 cm.
Lilygo T3S3
ESP32-S3 LoRa SX1280 2.4G development board. Contains an ESP32 chip, WIFI, Bluetooth and a LoRa module. Can be connected via serial, Bluetooth or network. Is supported by meshtastic. Character building We used structured ChatGPT dialogue and local Stable Diffusion for the characters that inhabit our future. Ask the archive for more info about them.
PrivateGPT
PrivateGPT is a set of libraries based on llama-index that allow local and offline inference using the computer‘s graphics card. PrivateGPT is particularly good at incorporating local documents. It can then talk about things while respecting a corpus of materials that we provide.
Transhumanism
Broadly, the idea that human beings can achieve their next evolutionary step, Human 2.0, through technological advances. Opinions differ as to how this post-human state will be achieved, either through genetic engineering, reverse aging or other technological advances. In our view, it is inspired by Social Darwinism.
Perception of Infrastructure
At its core, infrastructure is an evasive structure. Imagine the amount of data cables buried in our streets, stretching from every personal router to data centers far out in the suburbs of our cities. None of this actual “structure“ is meant to be seen or interacted with until it fails…
Network interface
We consider any device that has both user interactivity and Internet/network access to be a network interface.
Eco-Terrorism
Ecotage refers to infrastructure sabotage with ecological goals, while eco-terrorism is even more militant and will use militant strategies with the specific aim of creating terror as a social deterrent.
Prepping
Prepping is the act of preparing for the time after the catastrophe, resulting from the belief that current social models will collapse in an apocalyptic manner. Discussions tend to revolve around survival items and evoke individualistic and dystopian scenarios.
Infrastructure inversion
“rather than setting out to describe and document all parts of the system that make a footprint possible, the analysis focuses upon a selection of localized sites or issues as suggestive parts of a broader system that is imperceptible in its entirety” (Parks 2009)
Neo-Religion
The Internet, as a network of networks, is such a multifaceted term that it has room for spiritual feelings in the interaction with the network. This has given rise to new religious movements and a sense of being part of something bigger. Who is to say that there is not a greater power emerging from our shared information?
Neo-Luddism
Neo-Luddism is a leaderless movement of unaffiliated groups who resist modern technology by passively refraining from using technology, harming those who produce environmentally harmful technology, or sabotaging that technology.
Sub-sea-cables
Cables are often referred to as the backbone of the Internet. Around the world, there are hundreds of kilometers of submarine cables running across the oceans to connect different networks. They are heavy, expensive and buried deep in the sea. Chances are you have never seen one, yet you rely on them every day to deliver information and content.
Optical fiber cable
Fiber optic cables were developed in the 1980s. The first transatlantic telephone cable to use optical fiber was TAT-8, which went into service in 1988. A fiber optic cable consists of several pairs of fibers. Each pair has one fiber in each direction.
Copper cable
Copper is a rare metal and its use contributes to global neo-colonial power structures resulting in a multitude of exploitative practices. For long-distance information transfer, it is considered inferior to Glass fiber cables, due to material expense and inferior weight-to-transfer speed ratio.
Collapsology
Collapsology is based on the idea that humans are having a sustained and negative impact on their environment and promotes the concept of an environmental emergency, particularly in relation to global warming and the loss of biodiversity. One potential effect of a collapse is the loss of networks.
Posthumanism
Is concerned with the “ongoing deconstruction of humanism” and its premises: humanism’s anthropocentrism, essentialism and speciesism. It is informed by post-anthropocentric ethics, politics, and ecology, and looks toward notions of embodiment and material entanglement between humans and a “more-than-human” world. It emphasizes becoming over being.

This should document the rough steps to recreate airaspi as I go along.
Rough Idea: Build an edge device with image recognition and object detection capabilites. It should be realtime, aiming for 30fps at 720p. Portability and usage at installations is a priority, so it has to function without active internet connection and be as small as possible. It would be a real Edge Device, with no computation happening in the cloud.
Natural Language Understanding fascinates me and recently I started collaborating with the team of the Sommerblut Festival in Cologne to deliver them a customized chatbot that will be able to communicate with everyone, respecting accessibility standards to include all people. It will be able to communicate in German Sign Language (DGS), as well as service blind people, and we aim to incorporate the simple language concept.
I find it to be an amazing challenge to start out with the requirement of really being inclusive. In ordinary social contexts, it is often not obvious, but when analyzing the specific needs a blind person has browsing the internet, it is drastically different from a person having impaired hearing. To hold the same conversation with both of them is proving quite a challenge. And this is just the first step down into a very deep field of digital inclusiveness. How can people with a speech impediment use our tool? How do we include people speaking German as a foreign language?
Such vast challenges are often obfuscated by the technical framework of our digital lives.
I find digital accessibility a hugely interesting area, one that I am just now starting to explore.
This is a work in progress. We have some interesting ideas and will present a conceptual prototype, come check again after March 6th, when the 2022 festival started. Or come to the official digital presentation for the bot.
This bot is my first paid software work and I am getting to work with several awesome people and teams to realize different parts of the project. Here, I am not responsible for anything in the Front end, the product you will interact with here is by no means finished and may not respond at times, since we are moving and restarting it for production purposes. Nevertheless, all the intended core features of the bot are present and you can try it out there in the corner. If you wish to see more of the realization process, the entire project is on a public GitHub and is intended to ship as open source.
In the final version (for now), every single sentence will be accompanied by a video in German Sign Language (DGS). It can gracefully recover from some common input errors and can make live calls to external databases, displaying further information about all the events of the festival and teaching the Fingeralphabet. It supports free text input and is completely screen-reader compatible. It is scripted in easy language, to further facilitate access. It is mostly context-aware and features quite a bit of dynamic content generated based on user input.
I regard accessibility as a core question of both design and computation, really making tangible the prestructured way of our interaction with technology in general.
Update: we now have a launch date, which will be held online. Further information can be found here: Check out our Launch Event
Anmerkung
Update 2: The Chatbot is now online for a while already and finds itself in a "public beta", so to speak, a phase where it can be used and evaluated by users and is collecting feedback. Also, since this is Google, after all, all the inputs are collected and then further used to improve weak spots in the architecture of the bot. Find the public Chatbot

Ascendancy was an exploration of hacking states. Pirate Nations and Micronations have a rich history of challenging and ridiculing the concept of a nation state. Meet ascendancy, the portable, autonomous and self-moving state. Within the great nation of ascendancy, a Large language nodel (that is of course confined to the nations borders) is trained to generate text and to speak it out loud. It can be interacted with though an attached keyboard and screen. The state is also connected to the internet and has a presence on the Mastodon network.
Priority here was in the quick execution on local hardware. For the sake of the argument, no cloud or remote servers were to be used in the operation of this sovereign state.

Auraglow
Von Aron Petau, Sebastian Paintner und Milli Keil • 1 minute read •
What makes a room? How do moods and atmospheres emerge? Can we visualize them to make the experiences visible?
The project "The Nature of Objects" aims to expand (augment) perception by making the moods of places tangible through the respective auras of the objects in the space. What makes objects subjects? How can we make the implicit explicit? And how can we make the character of a place visible?\
Here, we question the conservative, purely physical concept of space and address in the project a temporal, historical component of space, its objects, and their past. Space will have transformed: from a simple "object on which interest, thought, action is directed" (definition object Duden), to a "creature that is endowed with consciousness, thinking, sensing, acting" (definition subject Duden). This metamorphosis of subject formation on objects enables the space to undergo changes influenced, or, more precisely a shaping, reshaping, deformation -such that the space can finally be perceived differently and multiangular.

Autoimmunitaet
Von Aron Petau, Milli Keil und Marla Gaiser • 2 Minuten gelesen •
In the context of the Design and Computation Studio Course Milli Keil, Marla Gaiser and me developed a concept for a playful critique of the traffic decisions we take and the idols we embrace. It should open up questions of whether the generations to come should still grow up playing on traffic carpets that are mostly grey and whether the Letzte Generation, a political climate activist group in Germany receives enough recognition for their acts.
A call for solidarity.

Autoimmunitaet
Autoimmunity is a term for defects, that are produced by a dysfunctional self-tolerance of a system. This dysfunction causes the immune system to stop accepting certain parts of itself and build antibodies instead. An invitation for a speculative playful interaction.
The Process
The figurines are 3D Scans of ourselves, in various typical poses of the Letzte Generation. We used photogrammetry to create the scans, which is a technique that uses a lot of photos of an object to create a 3D model of it. We used the app Polycam to create the scans using IPads and their inbuilt Lidar scanners.

-Übersetzung: Ballpark - Aron Petau
Implemented in Unity, Ballpark is a Concept work for a collaborative 2-Player Game, where one player is a navigator with a third-person perspective and another player is a copilot, responsible for interaction with the environment – featuring mostly working physics, intelligent enemies, a gun, a grappling hook system for traversing the map, a 2D Interface for navigation and a health bar system. On top of the meanest cyberpunk vibes my past self was able to conjure.
Enjoy!
As you can see, the design faces some questionable choices, but all mechanics are homemade from the ground up and I learned a lot. I often struggle to enjoy competitive games and think there is potential in a co-dependent game interface. During early testing, we often found that it enforces player communication since already the tutorial is quite hard to beat. Due to me being a leftie, perhaps not entirely smart, I gave player one the keyboard arrows to work with and player two the WASD keys and left and right mouse buttons for grappling and shooting. For the game, it has an interesting side effect, in that players are forced not only to interact through the differing information on each player's screen but also have to physically interact and coordinate the controls.
As you can perhaps see, the ball-rolling navigation is quite hard to use. It is a purely physics-based system, where, depending on the materiality of the ball, its weight, and therefore its inertia will drastically change.
On small screens, the prototype version of the game is virtually impossible to control and several visual bugs within the viewport still obfuscate items when they are too close. Considering that virtually all the mechanics are written from scratch, with a follow-me camera, collision detection, smart moving agents, and a still very wonky-looking grappling gun, I still think it deserves a spot in this portfolio. For this project I focused completely on the mechanics of the game, resulting in lots of used prefabs and readymade 3D Objects. Next time, I want to do that myself too.
I enjoyed my stint into Unity a lot and am looking forward to creating my first VR application and would love to try out some form of mechanics where the user vision is completely obfuscated by VR and they have to carry their eyes as a handheld connected camera so that the players can move around the camera itself with their hands.

Viel Spaß!
Das Design enthält einige fragwürdige Entscheidungen, aber alle Mechaniken sind von Grund auf selbst entwickelt, und ich habe viel dabei gelernt. Ich spiele selten kompetitive Spiele, sehe aber Potenzial in einer kooperativen, voneinander abhängigen Spielmechanik. Schon das Tutorial erfordert intensive Spielerkommunikation.
Als Linkshänder habe ich Spieler eins die Pfeiltasten gegeben und Spieler zwei die WASD-Tasten sowie die linken und rechten Maustasten für Schießen und Greifhaken. Das führt zu einem interessanten Nebeneffekt: Spieler müssen nicht nur über unterschiedliche Informationen auf ihren Bildschirmen kommunizieren, sondern auch ihre Steuerung physisch koordinieren.
Die Ball-Navigation ist ziemlich schwer zu kontrollieren. Es handelt sich um ein rein physikbasiertes System, bei dem Material, Gewicht und Trägheit der Kugel die Bewegung stark beeinflussen.
Auf kleinen Bildschirmen ist die Steuerung praktisch unmöglich, und einige visuelle Bugs verdecken Objekte bei zu naher Ansicht. Dennoch, da fast alle Mechaniken von Grund auf programmiert wurden – inklusive Follow-Camera, Kollisionsabfrage, smarten Agenten und einem noch etwas wackeligen Greifhaken – verdient das Projekt einen Platz im Portfolio.
Für dieses Projekt habe ich mich komplett auf Mechaniken konzentriert, weshalb viele fertige Prefabs und 3D-Objekte verwendet wurden. Beim nächsten Mal möchte ich diese auch selbst erstellen.
Ich habe Unity sehr genossen und freue mich darauf, meine erste VR-Anwendung zu entwickeln. Ich möchte Mechaniken ausprobieren, bei denen die Sicht des Spielers durch VR komplett blockiert wird und die Augen als tragbare, verbundene Kamera bewegt werden, sodass die Spieler die Kamera selbst physisch steuern können.

BEACON: Decentralizing the Energy Grid in inaccessible and remote regions
Access to Electricity is a basic human right. At first, that may seem over the top, but if one stops to think what all the little tasks that electricity can indirectly handle for us (lightning, laundry, cooking, freezing, heating, entertaining…) would consume in time and effort if we had to perform them manually, this idea becomes very clear. There are globally around 1 billion people without tier 2 access to electricity.
People only know the intensity of labor that goes into everything when there is no electricity. And it is not even only about convenience, electricity is an enormous lifesaver in any number of scenarios, think just of hospitals or mobile phone networks that would be rendered completely useless without it. So we can easily agree on a need, a demand for electricity globally, for every person. But what about the supply? Why is there 1 billion undersupplied? The Answer: missing profitability. It would be a charity project to supply every last person on earth, not a profitable one. And while charitable projects are noble and should be pursued, the reality within capitalism shows that this is not the way it is going to happen. But what if we could come up with technology, or rather, a communal structure, that enables us to supply profitably, and still adapt to both, the difficult external factors (weather issues, remoteness, altitude, etc.) and the smaller purses of the undersupplied?
Location
Towards the end of 2018, I spent 4 months in northern India, on a research project with the IIT Kharagpur. The goal was to work on one of the 17 UN-defined sustainable development goals – electricity.
Worldwide, an estimated 1 billion people have no or insubstantial access to the grid. Some of them live here, in the Key Monastery in the Spiti Valley at around 3500 meters altitude.
This is Tashi Gang, a village close to the Monastery. It houses around 50 people and only has road access during 3-4 months in the summer. For the rest of the time, the people rely on first aid services by helicopter, which can only be called with a working cell phone tower.
The Project
In an environment reliant on hydro-energy and solar (diesel transport is unreliable due to snowed-in mountain roads), over 6 months of snowy winter, frequent snowstorms, and temperatures of up to -35°C, securing the grid is hard.
Our way to tackle the issue was to reject the in the western society very established notion of electricity as a homogenous product with centralized production and instead researched the possibilities of a predictive, self-correcting, and decentral grid.
By prioritizing energy usage cases, instead of a full blackout during a storm, essential functions like radio towers and hospitals could be partially powered and maybe stay functioning. The binarity of either having electricity or not would be replaced by assigned quantities and timeslots, in a collective effort to be mindful and distribute the electricity necessity-based. The ultimate vision was a live predictive electricity market, where people could even earn money by selling their allotted, but not needed electricity. To gauge feasibility, I conducted several psychological acceptance studies and collected data on local electricity demands. I simulated a typical day of electricity demand in the Key monastery and the surrounding villages and mapped out the potential to install cost-efficient smart microgrid controllers enabling such an accurate and predictive behavior. The smart grid operator boxes available here in Germany cost several hundred, with installation several thousand Euros, not a feasible solution for the Indian population. Instead, we wanted to use Raspberry Pi's, which are interconnected through ethernet cables or local mesh networking.
Research
Data Collection
Building a questionnaire and visiting public schools during their English Classes, I had the chance to speak to a range of teenagers, answering questions about the state of electricity in their homes, generating more data than I could have accomplished running from door to door without any skills speaking local dialects. The questionnaire was as scientific as I could make it in such a situation and geared towards finding the type and number of electric devices in the homes and estimating typical usage scenarios.
With a total of 145 participants from more than 6 different schools and roughly 4 different districts, all located in the Indian part of the Himalayas, the findings are as follows:
The participants range from 11 to 53 years, with an average of 17 years. The average household has 6 members with an average of 5 smart devices. Only 2 percent of the Households had not a single smart device, but at the same time, only 42 percent had direct or indirect access to a laptop or computer. So the main body of smart devices consists of smartphones with a negligible portion of tablets. The average total amount of electrical devices is around 11 electrical appliances per house.
Subjective Quality Rating on a scale of 1 to 10:
Average quality in summer: 7.1 Average quality in monsoon: 5.6 Average quality in autumn: 7.1 Average quality in winter: 4.0
So, as you would expect, during winter, but also when it rains, the felt quality drops by more than 30 percent on average. As for the daily supply time, the average sits at 15.1 hours out of 24, meaning the people have electricity only for 62.9 percent of the time, some, as for example the people in Diskit only have a sad 4 hours of daily access. On top of that, this estimation does not account for the snowfalls in Spiti for example, where it is not uncommon to experience 3 consecutive days of powercut or more. As the Power Meter is supplied by the government, a solid 82 percent of the houses have a working power meter, if one assumes that the 13 percent who did not know whether they have a power meter, do have one, we can say that around 95% of the houses have a power meter.
Another goal of the studies was to find out what would incline people to be caring and sharing with the available electricity, something rather unimaginable here in Germany.
In general, the uninformed openness to delaying usage of electricity on a scale of 1-10 was around 5.5, with the additional information that a smart delay would cause an overall price reduction, the acceptance went up to 6.9, a good 14%. This implies that people would be a lot more inclined to give up conveniences if the benefits have a direct impact on them.
Simulation
After collecting all the estimated electric appliances of the local population, I simulated the use of 200 Solar Panels with 300Wp each, once for simultaneous electricity use, and once for mitigated electricity peaks through smart optimization and electricity usage delay.
Although solar is definitely not the optimal choice here and generates lots of issues with energy storage and battery charging at negative degrees, we figured that this was the way to go for the project. And as you can see, optimizing peak usage can improve solar from generating only one-fifth of the demand in winter to about half the demand in winter. Keeping in mind here, that the added solar farm was only intended to supply additional energy and not replace existing solutions, such a "small" farm would be a real lifesaver there and optimize the limited space in extremely mountainous terrain.
Closing words
There are to sides which the problems can be tackled: we can bring the total energy production up, by adding more panels or electricity by other means, but we can also try and bring the total demand down. This is to be achieved by investing strictly in the most energy-efficient appliances. Even replacing older, not-so-efficient appliances might sometimes be of use. But ensuring efficient use is not the only way to bring down the overall demand.
As introduced as core ideas for the whole project, sharing and delaying will prove immensely useful. How so? By sharing, we mean a concept that is already widely applied in the relevant areas. What to do in a Village that has no access to water? Will we send each household out to the faraway river to catch water for their family? Or would we join hands in a community effort to dig a central well used by everyone?
So, when we look at sharing electricity, how would we apply the concept? We take the appliances that consume the most energy individually and scale them up in order to increase efficiency. For example, in our case, that is most applicable to electric heating. If we manage to heat central community spaces available for everyone, naturally, fewer individual rooms will have to be heated. Similarly, one could declare a room as a public cinema, where people come together and watch Tv on a big Projector. Twice as fun, and conserving a great deal of energy again. Such ideas and others have to be realized in order to be able to match the total demand with the available supply.
Sadly, the project was never taken up further, and the situation for the people in the Spiti Valley has not improved. Two years ago, a road directly through the mountains was finished, making the population hopeful for an increase in tourism, increasing the chances of the economic viability of improved solutions. I spent my time there in the function of a research intern, having no real say in the realization of the project. The problem remains, and I still think that decentral solutions look to be the most promising for this specific location. Of course, the Himalayas present a bit of an extreme location, but that doesn't change the fact that people live there and have a basic human right to electricity.

BEACON: Dezentralisierung des Stromnetzes in unzugänglichen und abgelegenen Regionen
Zugang zu Elektrizität ist ein grundlegendes Menschenrecht. Das mag zunächst übertrieben klingen, doch wenn man bedenkt, wie viele kleine Aufgaben der Strom uns indirekt abnimmt – Licht, Wäsche, Kochen, Kühlen, Heizen, Unterhaltung – wird schnell klar, wie viel Zeit und Aufwand ohne Elektrizität nötig wäre. Weltweit leben etwa eine Milliarde Menschen ohne Zugang zu Strom auf dem sogenannten Tier-2-Level.
Menschen erkennen erst dann, wie viel Arbeit in alltäglichen Dingen steckt, wenn sie keinen Strom haben. Doch es geht dabei nicht nur um Bequemlichkeit – Elektrizität rettet Leben: Krankenhäuser, Telekommunikation, Kühlung von Medikamenten – all das hängt davon ab. Warum also sind immer noch so viele Menschen unterversorgt? Die Antwort: fehlende Rentabilität. Es wäre ein wohltätiges, aber kein profitables Projekt, jede Person auf der Welt zu versorgen. Doch was, wenn wir eine Struktur finden könnten, die wirtschaftlich tragfähig ist und sich gleichzeitig an schwierige Bedingungen (Wetter, Abgeschiedenheit, Höhenlage) sowie an kleinere Einkommen anpassen kann?
Standort
Ende 2018 verbrachte ich vier Monate im Norden Indiens – im Rahmen eines Forschungsprojekts mit dem IIT Kharagpur. Das Ziel: an einem der 17 von der UN definierten nachhaltigen Entwicklungsziele zu arbeiten – Elektrizität.
Weltweit haben schätzungsweise eine Milliarde Menschen keinen oder nur unzureichenden Zugang zum Stromnetz. Einige davon leben hier – im Key-Kloster im Spiti-Tal, auf etwa 3500 Metern Höhe.
Das ist Tashi Gang, ein Dorf nahe des Klosters. Es beherbergt rund 50 Menschen und ist nur drei bis vier Monate im Sommer über eine Straße erreichbar. Den Rest des Jahres sind die Bewohner auf Hubschrauber-Erste-Hilfe angewiesen – erreichbar nur über einen funktionierenden Mobilfunkturm.
Das Projekt
In einer Umgebung, die auf Wasser- und Sonnenenergie angewiesen ist, mit über sechs Monaten Schnee, häufigen Schneestürmen und Temperaturen bis zu –35 °C, ist die Netzsicherung schwierig.
Unser Ansatz war es, die im Westen etablierte Vorstellung von Elektrizität als homogenes, zentral erzeugtes Produkt zu hinterfragen und stattdessen die Möglichkeiten eines prädiktiven, sich selbst korrigierenden und dezentralen Netzes zu erforschen.
Anstatt bei einem Sturm einen kompletten Blackout zu riskieren, könnten bei einer Priorisierung der Energieverwendung wichtige Funktionen – etwa Radiotürme oder Krankenhäuser – teilweise weiterbetrieben werden. Die Binarität von Strom / kein Strom würde durch ein System von Zuteilungen nach Bedarf und Zeitfenstern ersetzt. Langfristig war die Vision ein lokaler, prädiktiver Strommarkt, bei dem Menschen überschüssige Energie verkaufen können.
Zur Machbarkeitsprüfung führte ich psychologische Akzeptanzstudien durch und sammelte Daten zum lokalen Stromverbrauch. Anschließend simulierte ich einen typischen Strombedarfstag im Key-Kloster und in den umliegenden Dörfern und entwickelte Konzepte für kostengünstige Smart-Microgrid-Controller.
Die hier in Deutschland verfügbaren Netzsteuerboxen kosten mehrere Hundert bis Tausend Euro – keine realistische Lösung für die Bevölkerung vor Ort. Stattdessen planten wir Raspberry Pi-basierte Systeme, vernetzt über Ethernet oder lokale Mesh-Netze.
Forschung
Datenerhebung
Durch den Besuch öffentlicher Schulen im Englischunterricht konnte ich mit Jugendlichen über den Stromzustand in ihren Haushalten sprechen und umfangreiche Daten erheben. Insgesamt nahmen 145 Teilnehmer aus über sechs Schulen in etwa vier Distrikten teil – alle im indischen Himalaya.
Der Altersdurchschnitt lag bei 17 Jahren. Durchschnittlich leben 6 Personen pro Haushalt mit etwa 5 Smart-Geräten. Nur 2 % der Haushalte hatten gar keine, 42 % verfügten über Computer oder Laptops.
Im Winter oder bei Regen sinkt die Qualität also deutlich – um über 30 %. Im Durchschnitt haben Haushalte 15,1 Stunden Strom pro Tag (≈ 63 %). Einige Regionen, wie Diskit, nur rund 4 Stunden.
Etwa 95 % der Haushalte besitzen funktionierende Stromzähler.
Ein weiteres Ziel war herauszufinden, was Menschen dazu bewegt, Strom zu teilen oder zu verschieben. Ohne zusätzliche Information lag die Bereitschaft zur Verzögerung des Verbrauchs bei 5,5 / 10 – mit Aussicht auf Kostenvorteile stieg sie auf 6,9.
Simulation
Basierend auf den Daten simulierte ich den Einsatz von 200 Solarmodulen à 300 Wp, einmal mit und einmal ohne intelligente Laststeuerung.
Auch wenn Solar nicht optimal ist – vor allem wegen Kälte und Batterielagerung – zeigte sich, dass intelligente Lastverteilung den nutzbaren Ertrag im Winter von einem Fünftel auf etwa die Hälfte steigern kann.
Schlusswort
Das Problem lässt sich aus zwei Richtungen angehen:
Produktion erhöhen – mehr Module, mehr Energiequellen.
Das Konzept des Teilens und Verzögerns ist zentral. Wie bei einem gemeinschaftlich genutzten Brunnen kann auch Strom gemeinschaftlich erzeugt und genutzt werden. Gemeinsam beheizte Räume oder öffentliche Projekträume sparen Energie und fördern Gemeinschaft.
Leider wurde das Projekt nie weitergeführt, und die Situation im Spiti-Tal hat sich kaum verbessert. Eine neue Bergstraße gibt Hoffnung auf mehr Tourismus – und damit auf wirtschaftlich tragfähige Lösungen.
Ich selbst war als Forschungspraktikant beteiligt, ohne Einfluss auf die Umsetzung. Dennoch bin ich überzeugt, dass dezentrale Lösungen der richtige Weg sind – gerade für extreme Regionen wie den Himalaya. Denn eines bleibt wahr: Elektrizität ist ein Menschenrecht.

-Übersetzung: 3D Modeling and CAD - Aron Petau
While learning about 3D Printing, I was most intrigued by the possibility to modify and repair existing products. While there is an amazing community with lots of good and free models around, naturally I came to a point where I did not find what I was looking for readily designed. I realized this is an essential skill for effectively operating not just 3D Printers, but any productive machine really.
Since youtube was the place I was learning all about 3D Printing, and all the people that I looked up to there were using Fusion 360 as their CAD Program that’s what I got into. In hindsight, that was a pretty good choice and I am in love with the abilities parametric design gives me. Below you will find some of my designs. The process is something that I enjoy a lot and wish to dive into deeper.
By trial and error, I already learned a lot about designing specifically for 3D Printing, but I often feel that there are many aesthetic considerations in design that I am not familiar with. I want to broaden my general ability to design physical objects, which is something I hope to gain during my master’s.
Check out more of my finished designs in the Prusaprinters (now Printables) Community
Besides coming up with new objects, incorporating the real world is also an interest of mine.
Interaction with real objects and environments
In the last few years I have played around with a few smartphone cameras and was always quite sad, that my scans were never quite accurate enough to do cool stuff with them. I could not really afford real 3D scanner and had already started cobbling together a raspberry Pi camera with a cheap TOF sensor, which is a simple, but not quite as good replacement for a laser or a lidar sensor, but then Apple came out with the first phones with accessible Lidar sensor. Recently, through work at the university I got access to a device with a lidar sensor and started having fun with it. See some examples here:
This last one was scanned with just my smartphone camera. You can see that the quality is notably worse, but considering is was created with just a single, run-of-the-mill smartphone sensor, I think it is still pretty impressive and will certainly do something towards democratizing such technologies and abilities.
Perspective
What this section is supposed to deliver is the message that I am currently not where I want to be navigating the vast possibilities of CAD. I feel confident enough to approach small repairs around the flat with a new perspective, but I still lack technical expertise when approaching a collection composite parts, having to function together. I still have lots of projects halfdone or half-thought and one major reason is that there is no real critical exchange within my field of study.
I want more than designing figurines or wearables. I want to incorporate 3D printing as a method to extend the abilities of other tools, have mechanical and electrical purposes, be foodsafe and engaging. I fell in love with the idea of designing a toy system, inspired by Makeways on Kickstarter, I have already started adding my own parts to their set.
I dream of my very own 3D printed coffeecup, one that is both foodsafe and dishwasher-surviving. For that, I would have to do quite a bit of material research, but that just makes the idea so much more appealing. I would love finding a material composition incorporating waste to stop relying on plastics, or at least on fossile plastics. Once in Berlin, I would want to talk to the people at Kaffeform producing largely compostable Coffee Cups incorporating a significant amount of old ground espresso, albeit using injection molding for their process. The industry selling composite filaments is much more conservative with the percentage of non-plastic additives, because with a nozzle extrusion process there is much more to go wrong. Still, I would love to explore that avenue further and think there is a lot to be gained from looking at pellet printers.
I also credit huge parts of my exploration process into local recycling to the awesome people at Precious Plastic, who I will join over the summer to learn more about their system.
I find it hard to write anything about CAD without connecting it directly to a manufacturing process. And I believe that's a good thing. Always tying a design process to its realization, grounds the process and attaches to it some immediacy.
For me to become more confident in this process, I am still missing more expertise in organic shapes, so I would be happy to dig more into Blender, an awesome tool that in my mind is far too powerful to dive into it with just youtube lessons.
Beim Erlernen des 3D-Drucks hat mich vor allem die Möglichkeit fasziniert, bestehende Produkte zu verändern oder zu reparieren. Auch wenn es eine großartige Community mit vielen guten und kostenlosen Modellen gibt, bin ich schnell an den Punkt gekommen, an dem ich nicht fand, was ich suchte. Mir wurde klar, dass dies eine wesentliche Fähigkeit ist, um nicht nur 3D-Drucker, sondern grundsätzlich jede Art von Produktionsmaschine sinnvoll zu nutzen.
Da ich alles über 3D-Druck auf YouTube gelernt habe und dort fast alle mit Fusion 360 arbeiteten, habe ich mich ebenfalls dafür entschieden. Rückblickend war das eine sehr gute Wahl – ich habe mich in die Möglichkeiten des parametrischen Designs verliebt. Unten findest du einige meiner Entwürfe. Der Prozess selbst macht mir unglaublich viel Spaß und ich möchte ihn noch weiter vertiefen.
Durch Ausprobieren habe ich bereits viel darüber gelernt, wie man speziell für den 3D-Druck konstruiert. Trotzdem habe ich oft das Gefühl, dass mir ein tieferes Verständnis für ästhetische Gestaltung fehlt. Ich möchte meine generelle Fähigkeit erweitern, physische Objekte zu entwerfen – etwas, das ich mir im Masterstudium erhoffe.
Mehr meiner fertigen Designs findest du in der Printables Community (früher Prusaprinters):
Neben dem Entwerfen neuer Objekte interessiert mich auch die Integration der realen Welt in meine Arbeit.
Interaktion mit realen Objekten und Umgebungen
In den letzten Jahren habe ich mit verschiedenen Smartphone-Kameras experimentiert – leider waren meine Scans meist nicht präzise genug, um wirklich etwas damit anzufangen. Ein professioneller 3D-Scanner war zu teuer, also bastelte ich mir eine Kombination aus einer Raspberry-Pi-Kamera und einem günstigen TOF-Sensor. Das Setup ist simpel, aber bei weitem nicht so genau wie Laser- oder LiDAR-Sensoren. Dann brachte Apple die ersten Geräte mit zugänglichem LiDAR heraus.
Durch meine Arbeit an der Universität hatte ich schließlich Zugriff auf ein Gerät mit LiDAR und begann, damit zu experimentieren. Ein paar Beispiele siehst du hier:
Der letzte Scan hier wurde nur mit einer Smartphone-Kamera erstellt. Man erkennt deutlich, dass die Qualität geringer ist, aber angesichts der einfachen Technik finde ich das Ergebnis beeindruckend – und es zeigt, wie sehr solche Technologien gerade demokratisiert werden.
Perspektive
Was dieser Abschnitt zeigen soll: Ich bin beim Thema CAD noch nicht da, wo ich gerne wäre. Ich fühle mich sicher genug, um kleine Reparaturen im Alltag anzugehen, aber beim Konstruieren komplexer Bauteilgruppen, die zusammen funktionieren müssen, fehlt mir noch technisches Know-how. Viele meiner Projekte sind halbfertig – einer der Hauptgründe ist der Mangel an fachlichem Austausch in meinem Umfeld.
Ich möchte mehr als nur Figuren oder Wearables gestalten. Ich möchte den 3D-Druck als Werkzeugerweiterung nutzen – für mechanische oder elektrische Anwendungen, lebensmittelechte Objekte, oder einfach Dinge, die begeistern. Ich liebe die Idee, ein Baukastensystem zu entwickeln. Inspiriert von Makeways auf Kickstarter habe ich bereits angefangen, eigene Teile zu entwerfen.
Ein Traum von mir ist eine eigene 3D-gedruckte Kaffeetasse, die sowohl spülmaschinenfest als auch lebensmittelecht ist. Dafür müsste ich viel Materialforschung betreiben – aber genau das macht es spannend. Ich möchte ein Material finden, das Abfälle einbezieht, um weniger von fossilen Kunststoffen abhängig zu sein. In Berlin möchte ich mich mit den Leuten von Kaffeform austauschen, die kompostierbare Becher aus gebrauchten Espressoresten herstellen (wenn auch per Spritzgussverfahren).
Die Hersteller von Komposit-Filamenten sind bei der Beimischung nicht-plastischer Stoffe sehr vorsichtig, weil der Extrusionsprozess durch Düsen leicht fehleranfällig ist. Trotzdem glaube ich, dass gerade in diesem Bereich noch viel Potenzial steckt – besonders mit Pelletdruckern.
Große Teile meiner Auseinandersetzung mit lokalem Recycling verdanke ich den großartigen Leuten von Precious Plastic, deren Open-Source-Designs mich sehr inspiriert haben. Ich finde es schwer, über CAD zu schreiben, ohne gleichzeitig über den Herstellungsprozess zu sprechen – und ich halte das für etwas Gutes. Design und Umsetzung gehören für mich zusammen.
Um noch sicherer zu werden, möchte ich mich stärker auf organische Formen konzentrieren. Deshalb will ich tiefer in Blender einsteigen – ein großartiges Tool, das viel zu mächtig ist, um es nur über YouTube zu lernen.
The central goal of the entire project was to make the Assistant be entirely speech controlled, such that the phone needn't be touched while immersing yourself in meditation.
The Chatbot was built in Google Dialogflow, a natural language understanding engine that can interpret free text input and identify entities and intents within it, We wrote a custom python backend to then use these evaluated intents and compute individualized responses.
The resulting application runs in Google Assistant and can adaptively deliver meditations, visualize sentiment history and comprehensively inform about meditation practices. Sadly, we used beta functionality from the older "Google Assistant" Framework, which got rebranded months after by Google into "Actions on Google" and changed core functionality requiring extensive migration that neither Chris, my partner in this project, nor I found time to do.
Nevertheless, the whole Chatbot functioned as a meditation player and was able to graph and store recorded sentiments over time for each user.
Attached below you can also find our final report with details on the programming and thought process.
After this being my first dip into using the Google Framework for the creation of a speech assistant and encountering many problems along the way that partly found their way also into the final report, now I managed to utilize these explorations and am currently working to create Ällei, another chatbot with a different focus, which is not realized within Actions on google, but will rather be getting its own react app on a website.

-Übersetzung: Coding Examples - Aron Petau
Although pure coding and debugging are often not a passion of mine, I recognize the importance of neural networks and other recent developments in Computer Vision. From several projects regarding AI and Machine Learning that I co-authored during my Bachelor Program, I picked this one since I think it is well documented and explains on a step-by-step basis what we do there.
Image Super-Resolution using Convolutional Neural Networks (Recreation of a 2016 Paper)
Image Super-Resolution is a hugely important topic in Computer Vision. If it works sufficiently advanced, we could take all our screenshots and selfies and cat pictures from the 2006 facebook-era and even from before and scale them up to suit modern 4K needs.
Just to give an example of what is possible in 2020, just 4 years after the paper here, have a look at this video from 1902:
The 2016 paper we had a look at is much more modest: it tries to upscale only a single Image, but historically, it was one of the first to achieve computing times sufficiently small to make such realtime-video-upscaling as visible in the Video (from 2020) or of the likes that Nvidia uses nowadays to upscale Videogames.
Example of a Super-Resolution Image. The Neural network is artificially adding Pixels so that we can finally put our measly selfie on a billboard poster and not be appalled by our deformed-and-pixelated-through-technology face.
A low-resolution sample
A high-resolution sample. This is also called 'ground truth'
The artificially enlarged image patch resulting from the algorithm
A graph showing an exemplary loss function applied during training
One qualitative measurement we used was pixel-wise cosine similarity. It is used to measure how similar the output and the ground truth images are
MTCNN (Application and Comparison of a 2016 Paper)
Here, you can also have a look at another, much smaller project, where we rebuilt a rather classical Machine learning approach for face detection. Here, we use preexisting libraries to demonstrate the difference in efficacy of approaches, showing that Multi-task Cascaded Convolutional Networks (MTCNN) was one of the best-performing approaches in 2016. Since I invested much more love and work into the above project, I would prefer for you to check that one out, in case two projects are too much.
Cars bad. Cars occupy public spaces resulting un a factual privatization of public goods/infrastructure. What if cars could be part of public infrastructure? What can cars provide to the public? With Solar and Electrical Vehicles emerging on the horizon (no endorsement here) it makes sense to think about cars as decentralized powerhouses and public energy storage solutions. Cars, even traditional ones, come equipped with batteries and generate electricity either by driving or though added solar panels. What if this energy could be used to power the public? What if cars would could be used as public spaces? By installing a public USB socket and a public wifi hotspot, on my car, I want to start exploring the potential of cars as public spaces and energy storage solutions.
Within this artistic experiment, I will continuously track the geolocation and energy input/output of my solar equipped car and make the data publicly available. I will also track the amount of energy that is not used by the car and could be used by the public. Taking steps towards optimal usage of existing electrical and other infrastructure is only possible by breaking conventional notions of public ownership and private property. This project is one step towards a more sustainable and equitable future.
Introduction
We all know by now that cars and individual traffic presents a major environmetal and societal problem all over the world. The last 70 something years of building car infrastructure are culminating in many areas in a dead end where the only thinkable solution is to build more roads and cars. THis is obviously a larger problem than one project can tackle, but here is one outlook on how
Experiment
Preexisting data
With the data collected over the last year of using the car privately I can show with embarrasing accuracy how underutilized the system is and calculate an estimate of energy lost due to societal notions of private property. The data will be an estimate, since the monitoring itself is dependent on solar energy and the internet connection is spotty at best when it is not supplied with electricity.
Monitoring
In the Car, there is a Raspberry Pi 4 Microcomputer running a custom Operating Systen that monitors the following data:
Solar Intake (W)
Battery Level (V)
GPS Location
Total Energy Produced (Wh)
Total Energy Consumed (Wh)
Solar Energy Potential (Wh)
Through the router I can also track total Wifi usage and the number of connected devices.
Public Wifi
For the Project, I opened a router in the Car towards the Public, much alike to ahotspot you would find in a cafe. I use my own data plan on there, which I never max out anyways. The router is a Netgear M1 and has a 4G Modem built in. It is connected to the Raspberry Pi and is powered by the secondary car battery.
Public Energy: A USB Socket
I plan on installing a USB Socket on the outside of the car, so people can charge their devices. The socket will be connected to the secondary car battery and will be powered by the solar panels. The socket will be installed in a way that it is not possible to drain the battery completely.
Communication
Nobody expects any help or public supplies from car owners. How to communicate the possibility to the outside world? The plan is to fabricate a vinyl sticker that will be applied to the car. The sticker will contain a QR Code that will lead to a website with the data and a short explanation of the project. Visual cues lead to the USB Socket and the Wifi Hotspot.
Issues
Space / Scale
Obviously, the space on top of a car is quite limited and from a sustainability perspective, it would be better to have a larger solar array on a roof of a house. The point is not to advocate for a mandated solar install on cars, but to optimize and share preexisting infrastructure. The car is already there, it already has a battery and it already has solar panels. Looking at many Camper-Van builds, the amount of cars with already installed solar panels is quite large. The point is to make the most out of it.
Legality
Germany has laws in place holding the owner of a Internet Connection liable for the legality of the traffic that is going through it. This is a major issue for the project, as I do not want to be liable for the traffic that is going through my car. I am currently looking into ways to circumvent this issue.
Surveillance / Privacy
The Car is equipped with a GPS Tracker and a Wifi Hotspot. This means that I can track the location of the car and the number of devices connected to the hotspot. I am not tracking any data that is going through the hotspot, but I could. As this project will generate public data, People using and maybe depending on the internet and electricity provided will be tracked by proxy. I am not sure how to deal with this issue yet. One potential solution would be to publish the data only in an aggregated form, but this would make the data less useful for other projects.
Security / Safety
My Car is now publicly traceable. I am no Elon Musk, and the idea does not really concern me, but we did create an additional attack vector for theft here.
It holds Geocodes, has hourly data and could tell the difference between geocoded potential solar energy and actual energy. It also has temperature records.
There are 2 types of Losses in the system:
Either the Batteries are full and available energy cannot be stored
Or the solar panels are blocked through urban structures and sub-optimal parking locations.
Interesting Questions:
How far away from optimal usage are my panels and where does the difference stem from?
Where to go?
I think, the difference between potential energy and actual electricity produced/consumed is interesting. How large is the gap? Is it relevant —> my initial guess would be that it is enormous How to close the gap?
—> install outside usb plugs It would be publicly available infrastructure, people could charge their smartphones anywhere —> QI charging for security concerns??
Scaling?? —> mandate solar roofs for cars? How effective would it actually be? What about buses / public vehicles?
+++
Potential issues with the data:
Spotty / intermittent internet connection
Noisy?
Making Cars public spaces
What could my car provide to the public to be less wasteful with its space?
Provide Internet
Would incur monthly costs
Provide Electricity
Concrete Problems
How to make sure people cannot fully drain my battery? How dangerous is actually an exposed USB Socket? Can people short my electronics through it?
How scalable are solutions like these?
Are public USBC Sockets something that would actually be used? Could there be a way for people to leave their stuff charging? What if I actually move the car and someone has their equipment still attached? Would people even leave their stuff unattended?
Can cars provide positive effects to public spaces? —> how to pose this research question without redeeming the presence of cars in our public spaces?
Difference Electric - Fuel cars
there is lots of research on using Electric cars as transitional energy storage. Even before "flatten the curve" became a common slogan, electrical engineers worried about the small energy spikes in the grid. The existence of these forces us to keep large power plants running at all times, even if the energy is not needed. The idea is to use the batteries of electric cars to store this energy and use it when needed.
Forum entries from the Seminar: Critical Epistemologies
On Anderson: Institutions
Anmerkung
Source Text: Epistemic Justice as a Virtue of Social Institutions Elizabeth Anderson (2012) Epistemic Justice as a Virtue of Social Institutions, Social Epistemology, 26:2, 163-173, DOI: 10.1080/02691728.2011.652211 Publication
The text by Anderson helped shed light on a few issues I stumbled over with Frickers Account. On top of the various issues I and seemingly others have with her virtue-based approach, I think a utilitarian angle is worth considering. That would be: okay, I accept that people can help fight injustice by realising their privilege, showing restraint, silencing themselves, and adopting the benevolent listening approach. I think that is a practical, virtuous, and realistic endeavour. But is it the effective path to alleviating structural injustice? I think not, and initially, that is a major reason I discarded Fricker’s approach, although I saw merit. I have similar concerns to Anderson in the scalability of virtues. Virtuous behavior might help my personal well-being, it gives me normative elevation and might even further the quality of relationships I have. But is it applicable to society, is it enough to counteract structural injustice? Well, maybe, assuming that:
Everyone realizes their privilege,
Everyone concludes that justice is the right goal,
Upon deciding to adopt a virtuous stance, everyone at least moderately succeeds in practicing what they preach.
I think, for society, the same society that came up with patriarchy in the first place, external pressure, some measure independent of the convictedness of the subjects is needed. Anderson made the powerful point of: “Anything that works, goes”, which took me some time to appreciate. I am always angry when I get told to keep my shower to a minimum or stop using plastic straws when I know exactly that my using less water is nothing compared to the institutionalized practice of Coca-Cola putting water into bottles. I feel like it is unjustified to ask me to save water while others triple their output, for performance. The same thing applies to Epistemic injustices. It strikes me how much energy it costs to keep up virtuous behavior individually and how little effect there is to show for it. I do not believe in “trickling up” where institutions will eventually adopt individual practices. Is Fricker thereby less right in her point? No, it adds up, as an entire population showering shorter adds up to lots of water saved. Anderson also points out how locally innocent biases can create injustice on a “macro” scale. Another indicator for me is that local virtue is not the sole solution, as it can still feed and sustain a system enforcing epistemic injustice.
I still have doubts about what to do now with my ideas, on how the world looks that I want. I lack the imagination of seeing a world that is epistemically just, and it is hard to strive for something one cannot even imagine. The system is inherently leaning toward inequality, if I try to balance something on a needle, it will only go well so long, before small imbalances create chain reactions and the object should be called unstable. Should we even succeed in “resetting” society, creating equal participation for each subject, how will it remain just? Is Justice always a conjunct of Equality? Are there ways to achieve real Justice without needing equality?

On Medina, the informant and the inquirer
Anmerkung
Source Text: Dr. José Medina (2012) Hermeneutical Injustice and Polyphonic Contextualism: Social Silences and Shared Hermeneutical Responsibilities, Social Epistemology, 26:2, 201-220, DOI: 10.1080/02691728.2011.652214 Publication
My biggest takeaway here was that, as I tried to hint at in an earlier comment, Whenever we talk about justice, this necessarily refers to a relational concept, where everybody has a double role to ensure successful communication. Medina calls these the inquirer and the informant. So, every individual has to make sure to act to her capacity as an epistemologically sound knowledge-acquiring agent (the inquirer). This would involve knowing when and how to falsify/qualify statements, making inferences about the theory of mind, and generally comparing different statements. The other role is the informant, where the individual should have the capacity to function as an object in an inquiry by another. Very roughly this can, I think, be compared to any good communication model, where there are a listener and a speaker, and both have to function. What was new here, or at least came out more clear is that it not only depends on the capacity of both of these roles on the subject, but it is also directly dependent on the “other”, the agent opposite of the subject. We may call this other society later but it helps me to visualize the other as an individual nonetheless. Where the analogy to communication now fails, in my opinion, is this cross-dependence, where an agent does not fully determine her capacity to act both as an inquirer and as an informant, it is co-determined by the “other”. So, if I, as an “other”, listen to someone's statements, and I fail or refuse to understand the epistemic content of the message, I am not only impairing my epistemic agency, but I also hurt the epistemic agency of the subject. Maybe obvious to most, but this thought struck me as being exactly the point of leverage for dysfunctionalities in power relations. Also argued convincingly in the paper was that these are distinct and independent agencies, which can be impairing an individual separately. Overall, the Medina text was incredibly helpful after the somewhat confusing Fricker text that felt incomplete and left a lot of questions for me. The medina text picked up all my initial doubts, that I couldn't properly formulate, and many more, while still holding to the general framework of Fricker. Although I was not convinced by the Fricker Text, I tend to think the strategy:
"When in doubt, give the subject full epistemic credibility"
Is a good strategy that might alleviate a lot of issues regarding functions of power, and hierarchy, but also further, it might be a good counter for things as our confirmation bias, expectation bias and many individual errors that we could minimize by constantly exposing ourselves to falsifiability through others (voluntarily). Sounds like science applied to agency to me.

On Jaggar: Norms, Outlaw Emotions, and the Ideal Society
Anmerkung
Source Text: Alison M. Jaggar (1989) Love and knowledge: Emotion in feminist epistemology, Inquiry, 32:2, 151-176, DOI: 10.1080/00201748908602185 Publication
I found Jaggar to be a very wholesome read, it was the perfect amount of grounded argumentative structure and felt very connected as a whole. This was, together with the ideas from Lugones the best and most fruitful paper for me. On outlaw emotions: First, I hate the term, I think it’s placative and fails to frame the (actually nice) idea behind it. Outlaw Emotions are all those emotions incompatible with the dominant norms. That’s a huge field to cover, among feminist emotions they would also encompass emotions that are irrational or “faulty”. So, Jaggar does the term Justice by saying, some, but not all Outlaw Emotions are Feminist emotions. To make this evident, just think of a murderer's joy for killing, it is of no feminist interest to dissect, yet it is against dominant values. So, experiencing Outlaw emotions is a (probably) necessary, but not sufficient condition for feminism. The incompatible emotion serves to create discourse and change. Jaggar convincingly shows how emotions have a direct influence on beliefs and can validly constitute evidence, while simultaneously validly influencing values in a similar manner. When we talk about dominant/alternative norms, we already endorse hierarchy in society. We acknowledge its existence, simply by identifying the dominant norm. I am not quite sure what exactly Jaggar proposes we should do with the hierarchy structures in society. Explicitly I can read: Subcultures rejecting dominant norms should be formed, to create counterbalances and a somewhat fair discourse over the topic. “How can we determine which outlaw emotions are to be endorsed or encouraged and which rejected? In what sense can we say that some emotional responses are more appropriate than others? What reason is there for supposing that certain alternative perceptions of the world, perceptions informed by outlaw emotions, are to be preferred to perceptions informed by conventional emotions? Here I can indicate only the general direction of an answer, whose full elaboration must await another occasion. I suggest that emotions are appropriate if they are characteristic of a society in which all Human Life (and perhaps some nonhuman life, too) thrive, or if they are conducive to establishing such a society.” To me this passage sounds sketchy at best, there is no indication of how to successfully separate appropriate from inappropriate emotions. Roughly, I read this part as: emotions are warranted iff they increase the balance of power. (equivalent to minimizing the height of the hierarchy) I would love to get to read this “other occasion” because it seems indefensible to me to formulate a norm that states: Accept only emotions which eliminate/diminish norms. The idea roughly resembles Rawls's Minimax Principle, where a policy should be implemented iff the benefit for the most disadvantaged is highest. Another thing I found helpful is her reformulation of what norms do: “Dominant Norms tend to serve dominant interests” til here nothing new, this is a tautology for me, I understand norms as identical to dominant interests, that’s literally what norms are. Is an alternative, suppressed norm even thinkable? Isn't it inherent in a norm that it be the dominant one? But then, after that: "Whatever our color / gender / class / sexual orientation, we are likely to adopt the dominant value of racist, classist, homophobe, misogynistic white men." This was rather helpful to me, as it reframes the “act” of oppression as the “likelihood of value distribution” being skewed in your favor, making everybody’s values more likely to be similar to yours. This nicely illustrates how a system can be hierarchical and oppressive, without anybody actively, intentionally “acting oppressive”, while still perpetuating oppression. I'm not saying everybody is acting unintentionally oppressive, but it is always hard to imagine for me to picture "White Men" forming a group and collectively deciding on who to hate this coming season, Conceptually separating "being oppressed" and "oppressing" into phenomena without necessary inherent causal relation makes sense to me here.

Source Text: Epistemic Justice as a Virtue of Social Institutions Elizabeth Anderson (2012) Epistemic Justice as a Virtue of Social Institutions, Social Epistemology, 26:2, 163-173, DOI: 10.1080/02691728.2011.652211 Publication
The text by Anderson helped shed light on a few issues I stumbled over with Frickers Account. On top of the various issues I and seemingly others have with her virtue-based approach, I think a utilitarian angle is worth considering. That would be: okay, I accept that people can help fight injustice by realising their privilege, showing restraint, silencing themselves, and adopting the benevolent listening approach. I think that is a practical, virtuous, and realistic endeavour. But is it the effective path to alleviating structural injustice? I think not, and initially, that is a major reason I discarded Fricker’s approach, although I saw merit. I have similar concerns to Anderson in the scalability of virtues. Virtuous behavior might help my personal well-being, it gives me normative elevation and might even further the quality of relationships I have. But is it applicable to society, is it enough to counteract structural injustice? Well, maybe, assuming that:
Everyone realizes their privilege,
Everyone concludes that justice is the right goal,
Upon deciding to adopt a virtuous stance, everyone at least moderately succeeds in practicing what they preach.
I think, for society, the same society that came up with patriarchy in the first place, external pressure, some measure independent of the convictedness of the subjects is needed. Anderson made the powerful point of: “Anything that works, goes”, which took me some time to appreciate. I am always angry when I get told to keep my shower to a minimum or stop using plastic straws when I know exactly that my using less water is nothing compared to the institutionalized practice of Coca-Cola putting water into bottles. I feel like it is unjustified to ask me to save water while others triple their output, for performance. The same thing applies to Epistemic injustices. It strikes me how much energy it costs to keep up virtuous behavior individually and how little effect there is to show for it. I do not believe in “trickling up” where institutions will eventually adopt individual practices. Is Fricker thereby less right in her point? No, it adds up, as an entire population showering shorter adds up to lots of water saved. Anderson also points out how locally innocent biases can create injustice on a “macro” scale. Another indicator for me is that local virtue is not the sole solution, as it can still feed and sustain a system enforcing epistemic injustice.
I still have doubts about what to do now with my ideas, on how the world looks that I want. I lack the imagination of seeing a world that is epistemically just, and it is hard to strive for something one cannot even imagine. The system is inherently leaning toward inequality, if I try to balance something on a needle, it will only go well so long, before small imbalances create chain reactions and the object should be called unstable. Should we even succeed in “resetting” society, creating equal participation for each subject, how will it remain just? Is Justice always a conjunct of Equality? Are there ways to achieve real Justice without needing equality?

On Medina, the informant and the inquirer
Anmerkung
Source Text: Dr. José Medina (2012) Hermeneutical Injustice and Polyphonic Contextualism: Social Silences and Shared Hermeneutical Responsibilities, Social Epistemology, 26:2, 201-220, DOI: 10.1080/02691728.2011.652214 Publication
My biggest takeaway here was that, as I tried to hint at in an earlier comment, Whenever we talk about justice, this necessarily refers to a relational concept, where everybody has a double role to ensure successful communication. Medina calls these the inquirer and the informant. So, every individual has to make sure to act to her capacity as an epistemologically sound knowledge-acquiring agent (the inquirer). This would involve knowing when and how to falsify/qualify statements, making inferences about the theory of mind, and generally comparing different statements. The other role is the informant, where the individual should have the capacity to function as an object in an inquiry by another. Very roughly this can, I think, be compared to any good communication model, where there are a listener and a speaker, and both have to function. What was new here, or at least came out more clear is that it not only depends on the capacity of both of these roles on the subject, but it is also directly dependent on the “other”, the agent opposite of the subject. We may call this other society later but it helps me to visualize the other as an individual nonetheless. Where the analogy to communication now fails, in my opinion, is this cross-dependence, where an agent does not fully determine her capacity to act both as an inquirer and as an informant, it is co-determined by the “other”. So, if I, as an “other”, listen to someone's statements, and I fail or refuse to understand the epistemic content of the message, I am not only impairing my epistemic agency, but I also hurt the epistemic agency of the subject. Maybe obvious to most, but this thought struck me as being exactly the point of leverage for dysfunctionalities in power relations. Also argued convincingly in the paper was that these are distinct and independent agencies, which can be impairing an individual separately. Overall, the Medina text was incredibly helpful after the somewhat confusing Fricker text that felt incomplete and left a lot of questions for me. The medina text picked up all my initial doubts, that I couldn't properly formulate, and many more, while still holding to the general framework of Fricker. Although I was not convinced by the Fricker Text, I tend to think the strategy:
"When in doubt, give the subject full epistemic credibility"
Is a good strategy that might alleviate a lot of issues regarding functions of power, and hierarchy, but also further, it might be a good counter for things as our confirmation bias, expectation bias and many individual errors that we could minimize by constantly exposing ourselves to falsifiability through others (voluntarily). Sounds like science applied to agency to me.

On Jaggar: Norms, Outlaw Emotions, and the Ideal Society
Anmerkung
Source Text: Alison M. Jaggar (1989) Love and knowledge: Emotion in feminist epistemology, Inquiry, 32:2, 151-176, DOI: 10.1080/00201748908602185 Publication
I found Jaggar to be a very wholesome read, it was the perfect amount of grounded argumentative structure and felt very connected as a whole. This was, together with the ideas from Lugones the best and most fruitful paper for me. On outlaw emotions: First, I hate the term, I think it’s placative and fails to frame the (actually nice) idea behind it. Outlaw Emotions are all those emotions incompatible with the dominant norms. That’s a huge field to cover, among feminist emotions they would also encompass emotions that are irrational or “faulty”. So, Jaggar does the term Justice by saying, some, but not all Outlaw Emotions are Feminist emotions. To make this evident, just think of a murderer's joy for killing, it is of no feminist interest to dissect, yet it is against dominant values. So, experiencing Outlaw emotions is a (probably) necessary, but not sufficient condition for feminism. The incompatible emotion serves to create discourse and change. Jaggar convincingly shows how emotions have a direct influence on beliefs and can validly constitute evidence, while simultaneously validly influencing values in a similar manner. When we talk about dominant/alternative norms, we already endorse hierarchy in society. We acknowledge its existence, simply by identifying the dominant norm. I am not quite sure what exactly Jaggar proposes we should do with the hierarchy structures in society. Explicitly I can read: Subcultures rejecting dominant norms should be formed, to create counterbalances and a somewhat fair discourse over the topic. “How can we determine which outlaw emotions are to be endorsed or encouraged and which rejected? In what sense can we say that some emotional responses are more appropriate than others? What reason is there for supposing that certain alternative perceptions of the world, perceptions informed by outlaw emotions, are to be preferred to perceptions informed by conventional emotions? Here I can indicate only the general direction of an answer, whose full elaboration must await another occasion. I suggest that emotions are appropriate if they are characteristic of a society in which all Human Life (and perhaps some nonhuman life, too) thrive, or if they are conducive to establishing such a society.” To me this passage sounds sketchy at best, there is no indication of how to successfully separate appropriate from inappropriate emotions. Roughly, I read this part as: emotions are warranted iff they increase the balance of power. (equivalent to minimizing the height of the hierarchy) I would love to get to read this “other occasion” because it seems indefensible to me to formulate a norm that states: Accept only emotions which eliminate/diminish norms. The idea roughly resembles Rawls's Minimax Principle, where a policy should be implemented iff the benefit for the most disadvantaged is highest. Another thing I found helpful is her reformulation of what norms do: “Dominant Norms tend to serve dominant interests” til here nothing new, this is a tautology for me, I understand norms as identical to dominant interests, that’s literally what norms are. Is an alternative, suppressed norm even thinkable? Isn't it inherent in a norm that it be the dominant one? But then, after that: "Whatever our color / gender / class / sexual orientation, we are likely to adopt the dominant value of racist, classist, homophobe, misogynistic white men." This was rather helpful to me, as it reframes the “act” of oppression as the “likelihood of value distribution” being skewed in your favor, making everybody’s values more likely to be similar to yours. This nicely illustrates how a system can be hierarchical and oppressive, without anybody actively, intentionally “acting oppressive”, while still perpetuating oppression. I'm not saying everybody is acting unintentionally oppressive, but it is always hard to imagine for me to picture "White Men" forming a group and collectively deciding on who to hate this coming season, Conceptually separating "being oppressed" and "oppressing" into phenomena without necessary inherent causal relation makes sense to me here.

-Übersetzung: Critical Philosophy of Subjectivity - Aron Petau
Citation from Butler, Page 51, citing Ewald, which is, in turn, interpreting Foucault:
The norm integrates anything which might attempt to go beyond it—nothing, nobody, whatever difference it might display, can ever claim to be exterior, or claim to possess an otherness which would actually make it other” (Norms, Discipline, and the Law, P.173)
Such a view suggests that any opposition to the norm is already contained within the norm, and is crucial to its functioning.
Here, for me, the entire futility of the approach later identified and described is condensed into a few sentences.
Hence, regulations that seek merely to curb certain specified activities (sexual harassment, welfare fraud, sexual speech) perform another activity that, for the most part, remains unmarked: the production of the parameters of personhood, that is, making persons according to abstract norms that at once condition and exceed the lives they make—and break. Page 56, final sentence
The idea that it is impossible to legislatively regulate norms without propelling, propagating, and carving them out deeper resonates with me, but at the same time, it has left me undecided on how to proceed. I understand the first citation to clearly be Ewald's interpretation of things and am not sure whether Foucault's careful circumvention of the term "Norms" is related to anticipation of this argument.
Further, I am not sure I share Ewald's interpretation; I see that the object "othered" by a norm is a constituent and necessary object for the norm, simply due to its "comparative" nature (p. 51, citation from Ewald). The oppressed may well be as constituting of norms as the privileged, but this does not translate to a normative responsibility nor a pang of guilt in my opinion. The dangerous argument that the oppressed bear responsibility for their situation is too close for my taste. I would like to emphasize a clear cut between constituting and reinforcing a norm and thriving on it. Yes, maybe that is a good location to make the cut: The normative and ethical pressure, or better, the guilt of complicity lies with the ones thriving BECAUSE of a norm and clearly not with those thriving DESPITE OF a norm. I would think that Butler makes a similar argument elsewhere, but as such, I was missing it here, resulting in a very bleak and hopeless situation where any struggle to change the status quo through legislation is doomed and inevitably propagates and reinvents stable unfair relations of power.
Anmerkung

Some tiny details about norms that stuck out to me about the norm were that: 1: they are fictional and thus, an object conforming to a norm is not more meaningful than an object not conforming to a norm. 2: the entire given set comprises the norm, the deviations play a defining role in the formation of the norm itself (or an average). p. 152: Under norm, 3 phenomena are subsumed: Discipline, less as a constraint, but more as a regulatory mechanism insurance, Reducing objects to their relative occurrence, distributing risk. and standardization. The norm has three defining features:
positivism, as reliant on facts, which have an aura of objectivity around them.
relativity, they are neither absolute nor universal, they have a scope, both in definition as a certain temporal extension.
polarity involving a classification between the normal and the abnormal, where the abnormal is to be some handicap, not attaining something that the normal does attain.
What, then, is a norm?
It is a way for a group to provide itself with a common denominator in accordance with a rigorous principle of self-referentiality, with no recourse to any kind of external reference point, either in the form of an idea or an object. The normative process can obey a variety of different logics: the panoptical logic of discipline, the probabilistic schema of insurance, or the communicative logic of the technical norm. These three logics have the same form: in each case, the rule which serves as a norm, by virtue of which everyone can measure, evaluate, and identify himself or herself, will be derived from those for whom it will serve as a standard. A strange logic, this, which forces the group to turn back in upon itself and which, from the moment it establishes itself, will let no one escape its purview. p. 154

On Foucault: The effects without effector
Anmerkung
Source Text: Michael Foucault. Power/knowledge: Selected interviews and other writings 1972–1977. Pantheon, New York, 1980. Publication
one finds all sorts of support mechanisms [...] which invent, modify and re-adjust, according to the circumstances of the moment and the place- so that you get a coherent, rational strategy, but one for which it is no longer possible to identify a person who conceived it. p. 203
In this passage, and the one following it, I think Foucault pinpoints as one of the central attributes of the apparatus (or dispositif) the arbitrariness of the order of power relations. There is no identity having to undergo some sort of inventive process to start off a collective change, a "strategy" just happens to meet the criteria for deployment.
But between the strategy which fixes, reproduces, multiplies and accentuates existing relations of forces, and the class which thereby finds itself in a ruling position, there is a reciprocal relation of production. Thus one can say that the strategy of moralising the working class is that of the bourgeoisie. One can even say that it's the strategy which allows the bourgeois class to be the bourgeois class and to exercise its domination. But what I don't think one can say is that it's the bourgeois class on the level of its ideology or its economic project which, as a sort of at once real and fictive subject, invented and forcibly imposed this strategy on the working class.
This was for me the most powerful grasp of what an apparatus is. A complicated removal of the effector from the effect. I struggle to continue to find any substance to the relations of the classes. Does reciprocal mean anything more than both are constitutive of each other? One produces the means of reproduction of the other, but where exactly can I apply moral judgements? This whole ordeal and now I lack subjects to blame. How can this theory possibly bring about change in society? Is that even its goal? Do we undergo this analysis in order to make society better in the end?

Dreams of Cars
These are not just cars. They are Sport Utility Vehicles. What might they have had as hopes and dreams on the production line? Do they dream of drifting in dusty deserts? Climbing steep rocky canyon roads? Sliding down sun-drenched dunes? Discovering remote pathways in natural grasslands? Nevertheless, they did end up in the parking spots here in Berlin.

The Collective Exibition Text:
Sound, as a fundamental element of everyday experience, envelopes us in the cacophony of city life - car horns, the chatter of pedestrians, the chirping of birds, the rustle of leaves in the wind, notifications, alarms and the constant hum of radio waves, signals and frequencies. These sounds, together make up the noise of our life, often pass by, fleeting and unnoticed. The engagement with sound through active listening holds the potential to process the experience of the self and its surroundings. This is the idea of “Echoing Dimensions”: Once you engage with something, it gives back to you: Whether it is the rhythmic cadence of a heartbeat, a flowing symphony of urban activity or the hoofbeats of a running horse, minds and bodies construct and rebuild scenes and narratives while sensing and processing the sounds that surround them, that pass next and through them. The exhibition "Echoing Dimensions" takes place at Kunstraum Potsdamer Straße gallery’s underground space and exhibits artworks by 12 Berlin based artists, who investigate in their artistic practice ‘intentional listening’ using sound, video and installation, and invites to navigate attentiveness by participatory exploration. Each artwork in the exhibition revolves around different themes in which historical ideas resonate, political-personal narratives are being re-conceptualized and cultural perspectives are examined. The exhibition's common thread lies in its interest into the complexities of auditory perception, inviting viewers to consider the ways in which sound shapes our memories, influences our culture, and challenges our understanding of space and power dynamics.

Working TD Prototype. We collect the pointcloud information through a kinect azure and sorting the output of the device turned out to be quite tricky.

Initial live testing on the finalized hardware. We decided to use a tiny Intel NUC to run both touchdesigner, the LLM, and audio synthesis.
Not expected at all: The audio synthesis was actually the hardest, since there was no available internet in the exhibition space and all sleek modern solutions seem to rely on cloud services to generate audio from text. Here, the tiny NUC really bit us: it took almost 15 seconds to generate a single paragraph of spoken words, even when usin quite small synthesizer models for it.
Lesson learned: Next time give it more oomph. I seriously wonder though why there wouldn't be better TTS systems around. Isnt that quite the essential accessibility feature? We ended up using coquiTTS, which is appearently out of business entirely.
This is a collection of Gallery Spaces and Collectives that provide a fresher and more counter-cultural perspective on the Gallery Weekend. It quite helped our online visibility and filled out the entire space on the Opening.

einszwovier: löten und leuchten
Von Aron Petau und Friedrich Weber Goizel • 4 Minuten gelesen •
Ein praxisnaher Kurs zu Löten, Elektronik und Lampendesign für junge Tüftler*innen
Löten und Leuchten fand inzwischen in drei erfolgreichen Durchläufen statt — jeweils als Angebot für Schüler*innen der 5. und 6. Klasse. Der Kurs bietet einen spielerischen und begleiteten Einstieg in die Welt der Elektronik, des Lötens und der digitalen Gestaltung. Im Mittelpunkt steht das Verstehen durch eigenes Machen: Technologien begreifen, indem man sie selbst gestaltet.
Das Projekt
Über drei Sitzungen hinweg (jeweils drei Stunden) entwickelten und bauten die Kinder ihre eigene USB-betriebene LED-Leuchte. Sie löteten elektronische Bauteile, modellierten Gehäuse in 3D, beschäftigten sich mit Lichtstreuung und lernten dabei ganz selbstverständlich, technische Probleme kreativ zu lösen. Jede Leuchte wurde von Grund auf gebaut, funktional und transportabel – ganz ohne Batterien, dafür mit echten Kabeln, Werkzeug und einem großen Schuss Eigenverantwortung.
Zum Einstieg lernten die Teilnehmer*innen die Grundlagen der Elektrizität mit den wunderbar zugänglichen Makey Makey-Boards kennen. Damit konnten wir spielerisch Stromkreise, Leitfähigkeit und Steuerung erklären – ein Einstieg, der sofort Neugier und Begeisterung weckte.
Anschließend folgte das Herzstück des Projekts: USB-Kabel aufschneiden, 5V-LEDs anlöten und eigene Gehäuse entwerfen. Das Löten geschah unter Aufsicht, aber jede*r lötete selbst – und das mit sichtbarem Stolz. Wenn die eigene LED zum ersten Mal leuchtet, ist das ein magischer Moment.
Gestaltung mit Werkzeug – und mit Einschränkungen
Für die 3D-Gestaltung nutzten wir Tinkercad auf iPads. Die Oberfläche war für viele der erste Berührungspunkt mit CAD-Software und erwies sich als zugänglich und intuitiv – allerdings nicht ohne technische Stolpersteine. Tinkercad stürzte gelegentlich ab, und Synchronisationsprobleme führten manchmal zu Verwirrung. Trotz dieser Hürden ermöglichte es einen niedrigschwelligen Einstieg in die digitale Gestaltung.
Die entworfenen Lampenschirme mussten nicht nur schön aussehen, sondern auch die Elektronik sinnvoll aufnehmen. Dadurch ergaben sich ganz reale Designherausforderungen: Passt das Kabel? Wie weit darf die LED vom Gehäuse entfernt sein? Wie verändert sich das Licht?
Gedruckt wurde mit weißem PLA-Filament – ideal für die Lichtstreuung. Im Kurs entwickelten sich dadurch ganz organisch Gespräche über Materialeigenschaften, Lichtdurchlässigkeit und die physikalischen Grenzen des 3D-Drucks.
Echte Herausforderungen, echtes Denken
Das Projekt traf genau die richtige Balance: anspruchsvoll genug, um ernst genommen zu werden, aber machbar genug, damit alle ein Erfolgserlebnis hatten. Jedes Kind nahm am Ende eine funktionierende, selbstgebaute Lampe mit nach Hause – und keine glich der anderen.
Dabei gab es viele kleine Hürden: USB-Kabel, die zu viel Spiel hatten, Gehäuse, die nicht sofort passten, LEDs, die nachjustiert werden mussten. Wir wichen diesen Herausforderungen nicht aus – im Gegenteil: Wir nutzten sie als Anlässe, um gemeinsam nach Lösungen zu suchen. Gerade diese Momente führten zu den besten Gesprächen über Technik, Entwurf und Fehlerkultur.
Bonus-Runde: Tischkicker-Prototypen
Zum Abschluss durfte jede Gruppe ihren eigenen Mini-Tischkicker entwerfen – mit den Materialien und Ideen, die sie zur Verfügung hatten. Diese kreative Extra-Aufgabe förderte Teamarbeit, Improvisation und erste Design-Thinking-Schritte. Und ganz nebenbei entstanden viele lustige, kluge und überraschende Lösungen.
Rückblick
Alle drei Durchgänge des Workshops wurden mit großem Interesse, Konzentration und Freude aufgenommen. Die Kinder waren über die gesamte Zeit engagiert, nicht nur beim Basteln, sondern auch im Denken: Wie funktioniert das? Was kann ich anders machen? Was ist möglich?
Sie gingen nicht nur mit einer leuchtenden Lampe nach Hause – sondern mit dem Gefühl, etwas selbst geschaffen zu haben. Und mit der Erkenntnis, dass Technik keine Zauberei ist, sondern etwas, das man verstehen und gestalten kann.
Auch für uns als Kursleitung war Löten und Leuchten ein bestärkendes Erlebnis. Die Kombination aus digitalen Werkzeugen, praktischer Arbeit und offener Aufgabenstellung schuf einen Raum, in dem Lernen ganz selbstverständlich und mit echter Neugier geschah.
Löten und Leuchten wird sich weiterentwickeln – doch das Ziel bleibt dasselbe: Kinder stärken, selbstbestimmt mit Technik umzugehen, und ihnen zeigen, dass sie mehr können, als sie denken.

einszwovier: making of
Von Aron Petau und Friedrich Weber Goizel • 2 Minuten gelesen •
Wir begannen mit dem Aufbau und der Planung der Raumgestaltung sowie der Ausstattung. Dabei hatten wir die Möglichkeit, die Werkbank selbst aus Holz zu bauen – so wurde sie zu etwas Eigenem.
Dezember 2024 – Ein Raum für Ideen wird Realität
Nach monatelanger Planung, Organisation und Vorfreude war es im Dezember 2024 endlich so weit: Unser Maker Space „studio einszwovier“ öffnete offiziell seine Türen. Mitten im Schulalltag entstand eine innovative Lernumgebung – eine, die Kreativität, Technologie und Bildungsgerechtigkeit miteinander verbindet.
Vom Konzept zur Wirklichkeit
Die Idee war klar: Ein Raum, in dem „Making“ greifbar wird – durch selbstbestimmtes und spielerisches Arbeiten mit analogen und digitalen Werkzeugen. Lernende sollen ihren Lernprozess mitgestalten, ihre individuellen Stärken entdecken und die motivierende Kraft des Selbermachens erleben.
Dazu wurde der Raum mit modernen Werkzeugen ausgestattet: 3D-Drucker, Lasercutter, Mikrocontroller sowie Equipment für Holzarbeiten und Textildruck ermöglichen praktisches, projektbasiertes Lernen.
Ein Ort für freies und entdeckendes Lernen
Geleitet von Aron und Friedrich – beide Masterstudenten im Studiengang Design + Computation in Berlin – bietet das „studio einszwovier“ Zugang zu Werkzeugen, Materialien und Wissen. Es ist ein Raum für offenes, exploratives Lernen, das nicht nur digitale Technologien, sondern auch Kreativität, Problemlösung und Eigeninitiative in den Mittelpunkt stellt. Die Schüler*innen sind eingeladen, sowohl an thematisch geführten Kursen als auch an offenen Tüftelzeiten teilzunehmen.
Offene Türen für kreative Köpfe
Das „studio einszwovier“ ist montags bis mittwochs von 11:00 bis 15:00 Uhr geöffnet. Eine spezielle Open Lab Time findet dienstags von 13:30 bis 15:00 Uhr statt. Alle sind herzlich eingeladen, vorbeizukommen, Ideen zu teilen und loszulegen.
Ein Raum für die Zukunft
Mit dem studio einszwovier haben wir einen Ort geschaffen, an dem das Lernen durch eigenes Tun im Mittelpunkt steht – und damit sowohl praktische als auch digitale Kompetenzen für die Zukunft gefördert werden. Ein Ort, an dem aus Ideen greifbare Ergebnisse entstehen und an dem die Lernkultur unserer Schule auf nachhaltige Weise wächst.

einszwovier: vogelvilla
Von Aron Petau und Friedrich Weber Goizel • 2 Minuten gelesen •
Nach unserem ersten Kurs, löten und leuchten, kam als nächste Idee auf, ein Format für den Lasercutter zu entwickeln. Dieses Mal richteten wir uns an ältere Kinder, ab der 9. Klasse. Wir haben uns auf 3Axis.co Inspiration geholt, und es war uns beiden wichtig, dass wir etwas Großes und Nützliches schaffen könnten. Ein Gruppenprojekt schien ideal, und wir haben uns ziemlich schnell auf Vogelhäuser festgelegt.
Im Space haben wir einen ziemlich großen und leistungsstarken Xtool S1, der bis zu 10 mm Sperrholz schneiden kann.
Aber ein Vogelhaus, mit all seinen Seiten, verbraucht am Ende doch einiges an Material, also haben wir ziemlich viel Vorbereitungszeit damit verbracht, das Basisdesign zu optimieren, sodass ein Haus mit nur 3 A3-Sperrholzplatten gebaut werden kann.
Wir haben ein Gelenk-Memory-Spiel erfunden, um das Nachdenken über die größeren Möglichkeiten des Lasercutters zu fördern. Während ihres eigenen Prozesses haben die Kinder selbst die Vor- und Nachteile von modularen oder reversiblen Designs herausgefunden und ihre eigenen Vogelhäuser komplett in Tinkercad und Xtool Creative Space entworfen. Wir hatten auch viel Spaß mit dem Lasercutter, und die Kinder konnten ihre eigenen Designs und Gravuren erstellen.
Wir haben den Kurs wieder auf 3 Tage ausgelegt, aber die notwendige Zeit für größere Schnitte und Gravuren etwas unterschätzt. Wir konnten die Vogelhäuser am dritten Tag nicht rechtzeitig fertigstellen, es fehlte jeweils nur noch weniger als eine Stunde für die Imprägnierung und letzte Details.

einszwovier: vogelvilla
Von Aron Petau und Friedrich Weber Goizel • 2 Minuten gelesen •
Nach unserem ersten Kurs, löten und leuchten, kam als nächste Idee auf, ein Format für den Lasercutter zu entwickeln. Dieses Mal richteten wir uns an ältere Kinder, ab der 9. Klasse. Wir haben uns auf 3Axis.co Inspiration geholt, und es war uns beiden wichtig, dass wir etwas Großes und Nützliches schaffen könnten. Ein Gruppenprojekt schien ideal, und wir haben uns ziemlich schnell auf Vogelhäuser festgelegt.
Im Space haben wir einen ziemlich großen und leistungsstarken Xtool S1, der bis zu 10 mm Sperrholz schneiden kann.
Aber ein Vogelhaus, mit all seinen Seiten, verbraucht am Ende doch einiges an Material, also haben wir ziemlich viel Vorbereitungszeit damit verbracht, das Basisdesign zu optimieren, sodass ein Haus mit nur 3 A3-Sperrholzplatten gebaut werden kann.
Wir haben ein Gelenk-Memory-Spiel erfunden, um das Nachdenken über die größeren Möglichkeiten des Lasercutters zu fördern. Während ihres eigenen Prozesses haben die Kinder selbst die Vor- und Nachteile von modularen oder reversiblen Designs herausgefunden und ihre eigenen Vogelhäuser komplett in Tinkercad und Xtool Creative Space entworfen. Wir hatten auch viel Spaß mit dem Lasercutter, und die Kinder konnten ihre eigenen Designs und Gravuren erstellen.
Wir haben den Kurs wieder auf 3 Tage ausgelegt, aber die notwendige Zeit für größere Schnitte und Gravuren etwas unterschätzt. Wir konnten die Vogelhäuser am dritten Tag nicht rechtzeitig fertigstellen, es fehlte jeweils nur noch weniger als eine Stunde für die Imprägnierung und letzte Details. Beim nächsten Mal würden wir daraus einen 4-Tage-Kurs machen :) Trotz des nicht ganz abgeschlossenen Projekts war das Feedback wieder gut und bot offenbar einen soliden Einstieg in die 2D-Blechfertigung und das Laserschneiden. Ein großes Dankeschön geht auch an unsere neue Lieblingsseite, Boxes.py, die eine Menge großartiger parametrischer Dateien bereitgestellt hat und besonders in Bezug auf die Verbindungsoptionen tolle Inspiration für die Kinder war.

-Übersetzung: Homebrew - Aron Petau
I love hosting, I love experimenting in the Kitchen. Starting with homebrews was a natural fit for me and during the first wave of Covid-19, I went the whole homebrewer’s route of bottle fermentation and small batches later elevating my game with larger batches of 50 liters and a pressure tank system.
Starting out, I found it fascinating, how just 4 rather simple ingredients, malt, hops, water and yeast, can form such an incredible range of taste experiences. It was and still is, a tremendous learning experience, where one slowly has to accept not being able to control the process fully and find room for creativity.
Why do I present such an unrelated non-academic hobby here? I simply do not regard it as unrelated, experimenting and optimizing a process and a workflow, creating optimal conditions for the yeast to do its job feels very similar to approaching a coding project. Yeast and what it does fascinates me. Every time I open the latch to release some pressure on the Tank I think of the awesome symbiotic relationships yeast has with humans and how many different strains live there together to create a unique, yet tailored flavor. Several ideas are floating around of changing the brewing process by capturing the created carbon dioxide and using it productively. I could see a car tire being filled with my beer gas, or an algae farm munching away on my CO2 byproducts. Within a closed-loop pressurized system, such ideas actually become realizable and I would love to explore them further.
I am not yet an expert on algae, but I can manage with yeast and I believe they can coexist and create a more sustainable cycle of production. Young Henrys, a brewery in Australia is already incorporating algae into its industrial process: The Algae project
Such ideas do not come into the industry by themselves: I believe that art and the exploratory discovery of novel techniques are the same things. Good and inventive design can improve society and make steps towards sustainability. I want to be part of that and would love to find new ways of using yeast in other design contexts: See whether I can make them work in a closed circular system, make them calculate things for me, or simply making my next beer taste awesome with just the right amount of fizz.

+Homebrew - Aron Petau
Ich liebe es zu veranstalten, ich liebe es, in der Küche zu experimentieren. Mit Homebrews zu starten, war für mich eine natürliche Entscheidung, und während der ersten Covid-19-Welle habe ich den kompletten Heimbräuerweg mit Flaschenfermentation und kleinen Chargen eingeschlagen, später habe ich mein Setup auf 50-Liter-Chargen mit Drucktank-System erweitert.
Zu Beginn war ich fasziniert, wie aus nur vier einfachen Zutaten – Malz, Hopfen, Wasser und Hefe – ein so unglaubliches Spektrum an Geschmackserlebnissen entstehen kann. Es war und ist immer noch ein tremendales Lernprojekt, bei dem man langsam akzeptieren muss, dass man den Prozess nicht vollständig kontrollieren kann, und gleichzeitig Raum für Kreativität findet.
Warum präsentiere ich dieses scheinbar nicht-akademische Hobby hier? Ich sehe es nicht als irrelevant an: Experimentieren und Optimieren eines Prozesses und Workflows, optimale Bedingungen für die Hefe zu schaffen, fühlt sich dem Ansatz eines Programmierprojekts sehr ähnlich an.
Hefe und ihre Wirkung faszinieren mich. Jedes Mal, wenn ich den Verschluss öffne, um etwas Druck aus dem Tank abzulassen, denke ich an die erstaunlichen symbiotischen Beziehungen der Hefe mit Menschen und wie viele verschiedene Stämme zusammenleben, um einen einzigartigen, maßgeschneiderten Geschmack zu erzeugen. Es gibt einige Ideen, den Brauprozess zu verändern, indem das erzeugte CO₂ aufgefangen und produktiv genutzt wird – z. B. ein Autoreifen gefüllt mit Biergas oder eine Algenfarm, die das CO₂ aufnimmt. Innerhalb eines geschlossenen, druckbeaufschlagten Systems werden solche Ideen tatsächlich realisierbar, und ich möchte sie weiter erforschen.
Ich bin noch kein Experte für Algen, aber mit Hefe komme ich klar, und ich glaube, dass sie koexistieren und einen nachhaltigeren Produktionszyklus schaffen können. Die australische Brauerei Young Henrys integriert Algen bereits in ihren industriellen Prozess: The Algae project
Solche Ideen kommen nicht von selbst in die Industrie: Ich glaube, dass Kunst und die experimentelle Entdeckung neuer Techniken dasselbe sind. Gutes, erfinderisches Design kann die Gesellschaft verbessern und Schritte in Richtung Nachhaltigkeit gehen. Ich möchte daran teilhaben und neue Wege finden, Hefe in anderen Designkontexten einzusetzen: ob in einem geschlossenen Kreislaufsystem, zum Berechnen von Dingen oder einfach, um mein nächstes Bier mit der perfekten Spritzigkeit zu brauen.

-Übersetzung: Iron Smelting - Aron Petau
Impressions from the International Smelting Days 2021
The concept
Since I was a small child I regularly took part in the yearly international congress called Iron Smelting Days (ISD). This is a congress of transdisciplinary people from all over Europe, including historians, archeologists, blacksmiths, steel producers, and many invested hobbyists. The proclaimed goal of these events is to understand the ancient production of iron as it happened throughout the iron age and also much after. A bloomery furnace was used to create iron. Making iron requires iron ore and heat under the exclusion of oxygen. It is a highly fragile process that takes an incredible amount of work. The designs and methods vary a lot and were very adapted to the region and local conditions, unlike the much later, more industrialized process using blast furnaces.
To this day it is quite unclear how prehistoric people managed to get the amount and quality of iron we know they had. The furnaces that were built were often clay structures and are not preserved. Archeologists often find the leftover burned ore and minerals, giving us some indication of the structure and composition of the ancient furnaces. The group around the ISD takes up a practical archeological approach and we try to recreate the ancient methods with the added capability of maybe sticking temperature probes or electric blowers. Each year we meet up in a different European city and try to adapt to the local conditions, often with local ore and local coal. It is a place where different areas of expertise come together to educate each other while sitting together through the intense day- and night shifts to feed the furnaces. Since being a kid, I started building my own furnaces and read up on the process so I could participate. Technology gets a different tint when one is involved in such a process: Even the lights we put up to work through the evening are technically cheating. We use thermometers, meticulously weigh and track the inbound coal and ore, and have many modern amenities around. Yet - with our much more advanced technology, our results are often inferior in quantity and quality in comparison with historical findings. Without modern scales, iron-age people were more accurate and consistent than we are.
After some uncertainty about whether it would take place in 2021 again after it was canceled in 2020, a small group met up in Ulft, Netherlands. This year in Ulft, another group made local coal, so that the entire process was even lengthier, and visitors came from all over to learn about making iron the pre-historic way.
Below I captured most of the process in some time-lapses.
The Process
Here you can see a timelapse of me building a version of an Iron Furnace
As you can see, we are using some quite modern materials, such as bricks, this is due to the time constraints of the ISD. Making an oven completely from scratch is a much more lengthy process requiring drying periods in between building.
After, the furnace is dried and heated up
Over the course of the process, more than 100 kgs of coal and around 20 kgs of ore are used to create a final piece of iron of 200 - 500g, just enough for a single knife.
With all the modern amenities and conveniences available to us, a single run still takes more than 3 people working over 72 hours, not accounting for the coal-making or mining and relocating the iron ore.
Some more impressions from the ISD

For me, it is very hard to define what technology encompasses. It certainly goes beyond the typically associated imagery of computing and industrial progress. It is a mode of encompassing the world and adopting other technologies, be it by time or by region makes me feel how diffused the phenomenon of technology is into my world.

One day earlier this year I woke up and realized I had a space problem. I was trying to build out a workshop and tackle ever more advanced and dusty plastic and woodworking projects and after another small run in with my girlfriend after I had repeatedly crossed the "No-Sanding-and-Linseed-Oiling-Policy" in our Living Room, it was time to do something about it. I am based in Berlin right now and the housing market is going completely haywire over here ( quick shoutout in solidarity with Deutsche Wohnen und Co enteignen). End of the song: I won't be able to afford to rent a small workshop anywhere near berlin anytime soon. As you will notice in some other projects, I am quite opposed to the Idea that it should be considered normal to park ones car in the middle of the city on public spaces, for example Autoimmunitaet, Commoning Cars or Dreams of Cars.
So, the idea was born, to regain that space as habitable zone, taking back usable space from parked cars. I was gonna install a mobile workshop within a trailer. Ideally, the trailer should be lockable and have enough standing and working space. As it turns out, Food Trailers fulfill these criteria quite nicely. So I got out on a quest, finding the cheapest food trailer available in germany.
6 weeks later, I found it near munich, got it and started immediately renovating it.
Due to developments in parallel, I was already invited to sell food and have the ofgficial premiere at the Bergfest, a Weekend Format in Brandenburg an der Havel, initiated and organized by Zirkus Creativo. Many thanks for the invitation here again!
So on it went, I spent some afternoons renovating and outfitting the trailer, and did my first ever shopping at Metro, a local B2B Foodstuffs Market.
Meanwhile, I got into all the paperwork and did all the necessary instructional courses and certificates. The first food I wanted to sell was Raclette on fresh bread, a swiss dish that is quite popular in germany. For the future, the trailer is supposed to tend more towards vegan dishes, as a first tryout I also sold a bruschetta combo. This turned out great, since the weather was quite hot and the bruschetta was a nice and light snack, while I could use the same type of bread for the raclette.
The event itself was great, and, in part at least, started paying off the trailer.

We encountered lots of positive feedback and I am looking forward to the next event. So, in case you want to have a foodtruck at your event, hit me up!
During 2022, I was exposed to some of the awesomenest tools for architects. One of them was Rhino, a 3D modeling software that is used for a lot of architectural design. I hate it. It has quite an unreadable interface and is not very intuitive, with straight-up 80s vibes. It has plugins though, and one of them is Grasshopper, a visual programming language that is used to create parametric models. Grasshopper is insanely powerful and seems to be a full-fledged programming language, but it is also very intuitive and easy to use, rather similar to the new node-based flows unreal engine and blender are now starting. Sadly, grasshopper does not come as a standalone, and it requires Rhino to run and achieve many of the modeling steps.
In that combination, Rhino suddenly becomes much more appealing, and I started to enjoy the process of modeling in it. I was able to create a parametric lampshade that I am very happy with and can modify on the fly for ever-new lampshades.
Then printing it with white filament in vase mode was a breeze and here you can see some of the results.

-Übersetzung: Local Diffusion - Aron Petau
Is it possible to create a graphic novel with generative A.I.? What does it mean to use these emerging media in collaboration with others? And why does their local and offline application matter?
With AI becoming more and more democratised and GPT-like Structures increasingly integrated into everyday life, the black-box notion of the mysterious all-powerful Intelligence hinders insightful and effective usage of emerging tools. One particularly hands-on example is AI generated images. Within the proposed Workshop, we will dive into Explainable AI, explore Stable Diffusion, and most importantly, understand the most important parameters within it. We want to steer outcomes in a deliberate manner. Emphasis here is on open and accessible technology, to increase user agency and make techno-social dependencies and power relations visible.
Empower yourself against readymade technology! Do not let others decide on what your best practices are. Get involved in the modification of the algorithm and get surprised by endless creative possibilities. Through creating a short graphic novel with 4-8 panels, participants will be able to utilise multiple flavours of the Stable Diffusion algorithm, and will have a non-mathematical understanding of the parameters and their effects on the output within some common GUIs. They will be able to apply several post-processing techniques to their generated images, such as upscaling, masking, inpainting and pose redrawing. Further, participants will be able to understand the structure of a good text prompt, be able to utilise online reference databases and manipulate parameters and directives of the Image to optimise desired qualities. Participants will also be introduced to ControlNet, enabling them to direct Pose and Image composition in detail.
Workshop Evaluation
Over the course of 3 hours, I gave an introductory workshop in local stable diffusion processing and introduced participants to the server available to UdK Students for fast remote computation that circumvents the unethicality of continuously using a proprietary cloud service for similar outputs. There is not much we can do on the data production side and many ethical dilemmas surrounding digital colonialism remain, but local computation takes one step towards a critical and transparent use of AI tools by Artists.
The Workshop format was rathert open and experimental, which was welcomed by the participants and they tried the collages enthusiastically. We also had a refreshing discussion on different positions regarding the ethicalities and whether a complete block of these tools is called for and feasible.
I am looking forward to round 2 with the next iteration, where we are definitely diving deeper into the depths of comfyui, an interface that i absolutely adore, while its power also terrifies me sometimes.

Plastics offer significant material benefits, such as durability and versatility, yet their widespread use has led to severe environmental pollution and waste management challenges. This thesis develops alternative concepts for collaborative participation in recycling processes by examining existing waste management systems. Exploring the historical and material context of plastics, it investigates the role of making and hacking as transformative practices in waste revaluation. Drawing on theories from Discard Studies, Material Ecocriticism, and Valuation Studies, it applies methods to examine human-waste relationships and the shifting perception of objects between value and non-value. Practical investigations, including workshop-based experiments with polymer identification and machine-based interventions, provide hands-on insights into the material properties of discarded plastics. These experiments reveal their epistemic potential, leading to the introduction of novel archiving practices and knowledge structures that form an integrated methodology for artistic research and practice. Inspired by the Materialstudien of the Bauhaus Vorkurs, the workshop not only explores material engagement but also offers new insights for educational science, advocating for peer-learning scenarios. Through these approaches, this research fosters a socially transformative relationship with waste, emphasizing participation, design, and speculative material reuse. Findings are evaluated through participant feedback and workshop outcomes, contributing to a broader discussion on waste as both a challenge and an opportunity for sustainable futures and a material reality of the human experience.

I have attended a fair share of philosophical seminars in my studies and consider it a core topic connected both to science and to digital environments. Normative and feminist social theory, as well as the theory of science and phenomenology, are all brought to me through seminar formats at university and made up a good part of my education there. I find it hard to properly demonstrate what interests me without presenting often long-winded and dull term papers. The courses I loved most also often had a format with a weekly hand-in, where students are asked to comment on the paper they just read to identify points to carry into next week's discussion. I am incredibly thankful for this methodology of approaching complex philosophical works, often complete books with supplicant essays surrounding the course topic. In my opinion, nearly all of the value created during these seminars is contained within the live discussions fed by reading materials and little opinion pieces in the form of forum comments. That's why I decided to share here a selection of these weekly commentaries and the sources they are based upon. They are often unrefined and informal, but they indicate the centerpiece of the seminars and demonstrate many thought processes that happened within me during these sessions. Although I took only a small selection, in sum they are a substantial read. Feel free to just skip through and read what catches your interest.
Forum entries from the Seminar: Critical Epistemologies
On Anderson: Institutions
Anmerkung
Source Text: Epistemic Justice as a Virtue of Social Institutions Elizabeth Anderson (2012) Epistemic Justice as a Virtue of Social Institutions, Social Epistemology, 26:2, 163-173, DOI: 10.1080/02691728.2011.652211 Publication
The text by Anderson helped shed light on a few issues I stumbled over with Frickers Account. On top of the various issues I and seemingly others have with her virtue-based approach, I think a utilitarian angle is worth considering. That would be: okay, I accept that people can help fight injustice by realising their privilege, showing restraint, silencing themselves, and adopting the benevolent listening approach. I think that is a practical, virtuous, and realistic endeavour. But is it the effective path to alleviating structural injustice? I think not, and initially, that is a major reason I discarded Fricker’s approach, although I saw merit. I have similar concerns to Anderson in the scalability of virtues. Virtuous behavior might help my personal well-being, it gives me normative elevation and might even further the quality of relationships I have. But is it applicable to society, is it enough to counteract structural injustice? Well, maybe, assuming that:
Everyone realizes their privilege,
Everyone concludes that justice is the right goal,
Upon deciding to adopt a virtuous stance, everyone at least moderately succeeds in practicing what they preach.
I think, for society, the same society that came up with patriarchy in the first place, external pressure, some measure independent of the convictedness of the subjects is needed. Anderson made the powerful point of: “Anything that works, goes”, which took me some time to appreciate. I am always angry when I get told to keep my shower to a minimum or stop using plastic straws when I know exactly that my using less water is nothing compared to the institutionalized practice of Coca-Cola putting water into bottles. I feel like it is unjustified to ask me to save water while others triple their output, for performance. The same thing applies to Epistemic injustices. It strikes me how much energy it costs to keep up virtuous behavior individually and how little effect there is to show for it. I do not believe in “trickling up” where institutions will eventually adopt individual practices. Is Fricker thereby less right in her point? No, it adds up, as an entire population showering shorter adds up to lots of water saved. Anderson also points out how locally innocent biases can create injustice on a “macro” scale. Another indicator for me is that local virtue is not the sole solution, as it can still feed and sustain a system enforcing epistemic injustice.
I still have doubts about what to do now with my ideas, on how the world looks that I want. I lack the imagination of seeing a world that is epistemically just, and it is hard to strive for something one cannot even imagine. The system is inherently leaning toward inequality, if I try to balance something on a needle, it will only go well so long, before small imbalances create chain reactions and the object should be called unstable. Should we even succeed in “resetting” society, creating equal participation for each subject, how will it remain just? Is Justice always a conjunct of Equality? Are there ways to achieve real Justice without needing equality?

On Medina, the informant and the inquirer
Anmerkung
Source Text: Dr. José Medina (2012) Hermeneutical Injustice and Polyphonic Contextualism: Social Silences and Shared Hermeneutical Responsibilities, Social Epistemology, 26:2, 201-220, DOI: 10.1080/02691728.2011.652214 Publication
My biggest takeaway here was that, as I tried to hint at in an earlier comment, Whenever we talk about justice, this necessarily refers to a relational concept, where everybody has a double role to ensure successful communication. Medina calls these the inquirer and the informant. So, every individual has to make sure to act to her capacity as an epistemologically sound knowledge-acquiring agent (the inquirer). This would involve knowing when and how to falsify/qualify statements, making inferences about the theory of mind, and generally comparing different statements. The other role is the informant, where the individual should have the capacity to function as an object in an inquiry by another. Very roughly this can, I think, be compared to any good communication model, where there are a listener and a speaker, and both have to function. What was new here, or at least came out more clear is that it not only depends on the capacity of both of these roles on the subject, but it is also directly dependent on the “other”, the agent opposite of the subject. We may call this other society later but it helps me to visualize the other as an individual nonetheless. Where the analogy to communication now fails, in my opinion, is this cross-dependence, where an agent does not fully determine her capacity to act both as an inquirer and as an informant, it is co-determined by the “other”. So, if I, as an “other”, listen to someone's statements, and I fail or refuse to understand the epistemic content of the message, I am not only impairing my epistemic agency, but I also hurt the epistemic agency of the subject. Maybe obvious to most, but this thought struck me as being exactly the point of leverage for dysfunctionalities in power relations. Also argued convincingly in the paper was that these are distinct and independent agencies, which can be impairing an individual separately. Overall, the Medina text was incredibly helpful after the somewhat confusing Fricker text that felt incomplete and left a lot of questions for me. The medina text picked up all my initial doubts, that I couldn't properly formulate, and many more, while still holding to the general framework of Fricker. Although I was not convinced by the Fricker Text, I tend to think the strategy:
"When in doubt, give the subject full epistemic credibility"
Is a good strategy that might alleviate a lot of issues regarding functions of power, and hierarchy, but also further, it might be a good counter for things as our confirmation bias, expectation bias and many individual errors that we could minimize by constantly exposing ourselves to falsifiability through others (voluntarily). Sounds like science applied to agency to me.

On Jaggar: Norms, Outlaw Emotions, and the Ideal Society
Anmerkung
Source Text: Alison M. Jaggar (1989) Love and knowledge: Emotion in feminist epistemology, Inquiry, 32:2, 151-176, DOI: 10.1080/00201748908602185 Publication
I found Jaggar to be a very wholesome read, it was the perfect amount of grounded argumentative structure and felt very connected as a whole. This was, together with the ideas from Lugones the best and most fruitful paper for me. On outlaw emotions: First, I hate the term, I think it’s placative and fails to frame the (actually nice) idea behind it. Outlaw Emotions are all those emotions incompatible with the dominant norms. That’s a huge field to cover, among feminist emotions they would also encompass emotions that are irrational or “faulty”. So, Jaggar does the term Justice by saying, some, but not all Outlaw Emotions are Feminist emotions. To make this evident, just think of a murderer's joy for killing, it is of no feminist interest to dissect, yet it is against dominant values. So, experiencing Outlaw emotions is a (probably) necessary, but not sufficient condition for feminism. The incompatible emotion serves to create discourse and change. Jaggar convincingly shows how emotions have a direct influence on beliefs and can validly constitute evidence, while simultaneously validly influencing values in a similar manner. When we talk about dominant/alternative norms, we already endorse hierarchy in society. We acknowledge its existence, simply by identifying the dominant norm. I am not quite sure what exactly Jaggar proposes we should do with the hierarchy structures in society. Explicitly I can read: Subcultures rejecting dominant norms should be formed, to create counterbalances and a somewhat fair discourse over the topic. “How can we determine which outlaw emotions are to be endorsed or encouraged and which rejected? In what sense can we say that some emotional responses are more appropriate than others? What reason is there for supposing that certain alternative perceptions of the world, perceptions informed by outlaw emotions, are to be preferred to perceptions informed by conventional emotions? Here I can indicate only the general direction of an answer, whose full elaboration must await another occasion. I suggest that emotions are appropriate if they are characteristic of a society in which all Human Life (and perhaps some nonhuman life, too) thrive, or if they are conducive to establishing such a society.” To me this passage sounds sketchy at best, there is no indication of how to successfully separate appropriate from inappropriate emotions. Roughly, I read this part as: emotions are warranted iff they increase the balance of power. (equivalent to minimizing the height of the hierarchy) I would love to get to read this “other occasion” because it seems indefensible to me to formulate a norm that states: Accept only emotions which eliminate/diminish norms. The idea roughly resembles Rawls's Minimax Principle, where a policy should be implemented iff the benefit for the most disadvantaged is highest. Another thing I found helpful is her reformulation of what norms do: “Dominant Norms tend to serve dominant interests” til here nothing new, this is a tautology for me, I understand norms as identical to dominant interests, that’s literally what norms are. Is an alternative, suppressed norm even thinkable? Isn't it inherent in a norm that it be the dominant one? But then, after that: "Whatever our color / gender / class / sexual orientation, we are likely to adopt the dominant value of racist, classist, homophobe, misogynistic white men." This was rather helpful to me, as it reframes the “act” of oppression as the “likelihood of value distribution” being skewed in your favor, making everybody’s values more likely to be similar to yours. This nicely illustrates how a system can be hierarchical and oppressive, without anybody actively, intentionally “acting oppressive”, while still perpetuating oppression. I'm not saying everybody is acting unintentionally oppressive, but it is always hard to imagine for me to picture "White Men" forming a group and collectively deciding on who to hate this coming season, Conceptually separating "being oppressed" and "oppressing" into phenomena without necessary inherent causal relation makes sense to me here.

Forum entries from the Seminar: Critical Philosophy of Subjectivity 1: Michel Foucault
On Butler: Constituting norms =/= carrying normative responsibilities for their existence
Citation from Butler, Page 51, citing Ewald, which is, in turn, interpreting Foucault:
The norm integrates anything which might attempt to go beyond it—nothing, nobody, whatever difference it might display, can ever claim to be exterior, or claim to possess an otherness which would actually make it other” (Norms, Discipline, and the Law, P.173)
Such a view suggests that any opposition to the norm is already contained within the norm, and is crucial to its functioning.
Here, for me, the entire futility of the approach later identified and described is condensed into a few sentences.
Hence, regulations that seek merely to curb certain specified activities (sexual harassment, welfare fraud, sexual speech) perform another activity that, for the most part, remains unmarked: the production of the parameters of personhood, that is, making persons according to abstract norms that at once condition and exceed the lives they make—and break. Page 56, final sentence
The idea that it is impossible to legislatively regulate norms without propelling, propagating, and carving them out deeper resonates with me, but at the same time, it has left me undecided on how to proceed. I understand the first citation to clearly be Ewald's interpretation of things and am not sure whether Foucault's careful circumvention of the term "Norms" is related to anticipation of this argument.
Further, I am not sure I share Ewald's interpretation; I see that the object "othered" by a norm is a constituent and necessary object for the norm, simply due to its "comparative" nature (p. 51, citation from Ewald). The oppressed may well be as constituting of norms as the privileged, but this does not translate to a normative responsibility nor a pang of guilt in my opinion. The dangerous argument that the oppressed bear responsibility for their situation is too close for my taste. I would like to emphasize a clear cut between constituting and reinforcing a norm and thriving on it. Yes, maybe that is a good location to make the cut: The normative and ethical pressure, or better, the guilt of complicity lies with the ones thriving BECAUSE of a norm and clearly not with those thriving DESPITE OF a norm. I would think that Butler makes a similar argument elsewhere, but as such, I was missing it here, resulting in a very bleak and hopeless situation where any struggle to change the status quo through legislation is doomed and inevitably propagates and reinvents stable unfair relations of power.

Some tiny details about norms that stuck out to me about the norm were that: 1: they are fictional and thus, an object conforming to a norm is not more meaningful than an object not conforming to a norm. 2: the entire given set comprises the norm, the deviations play a defining role in the formation of the norm itself (or an average). p. 152: Under norm, 3 phenomena are subsumed: Discipline, less as a constraint, but more as a regulatory mechanism insurance, Reducing objects to their relative occurrence, distributing risk. and standardization. The norm has three defining features:
positivism, as reliant on facts, which have an aura of objectivity around them.
relativity, they are neither absolute nor universal, they have a scope, both in definition as a certain temporal extension.
polarity involving a classification between the normal and the abnormal, where the abnormal is to be some handicap, not attaining something that the normal does attain.
What, then, is a norm?
It is a way for a group to provide itself with a common denominator in accordance with a rigorous principle of self-referentiality, with no recourse to any kind of external reference point, either in the form of an idea or an object. The normative process can obey a variety of different logics: the panoptical logic of discipline, the probabilistic schema of insurance, or the communicative logic of the technical norm. These three logics have the same form: in each case, the rule which serves as a norm, by virtue of which everyone can measure, evaluate, and identify himself or herself, will be derived from those for whom it will serve as a standard. A strange logic, this, which forces the group to turn back in upon itself and which, from the moment it establishes itself, will let no one escape its purview. p. 154

On Foucault: The effects without effector
Anmerkung
Source Text: Michael Foucault. Power/knowledge: Selected interviews and other writings 1972–1977. Pantheon, New York, 1980. Publication
one finds all sorts of support mechanisms [...] which invent, modify and re-adjust, according to the circumstances of the moment and the place- so that you get a coherent, rational strategy, but one for which it is no longer possible to identify a person who conceived it. p. 203
In this passage, and the one following it, I think Foucault pinpoints as one of the central attributes of the apparatus (or dispositif) the arbitrariness of the order of power relations. There is no identity having to undergo some sort of inventive process to start off a collective change, a "strategy" just happens to meet the criteria for deployment.
But between the strategy which fixes, reproduces, multiplies and accentuates existing relations of forces, and the class which thereby finds itself in a ruling position, there is a reciprocal relation of production. Thus one can say that the strategy of moralising the working class is that of the bourgeoisie. One can even say that it's the strategy which allows the bourgeois class to be the bourgeois class and to exercise its domination. But what I don't think one can say is that it's the bourgeois class on the level of its ideology or its economic project which, as a sort of at once real and fictive subject, invented and forcibly imposed this strategy on the working class.
This was for me the most powerful grasp of what an apparatus is. A complicated removal of the effector from the effect. I struggle to continue to find any substance to the relations of the classes. Does reciprocal mean anything more than both are constitutive of each other? One produces the means of reproduction of the other, but where exactly can I apply moral judgements? This whole ordeal and now I lack subjects to blame. How can this theory possibly bring about change in society? Is that even its goal? Do we undergo this analysis in order to make society better in the end?

Forum entries from the Seminar: Is political violence justifiable? Reading Judith Butler and Elsa Dorlin
From the seventh chapter in Dorlins "Self-Defense", I found the idea that safe spaces are actually prone to be counterproductive very strong. I think the discussion around whether safe spaces are an effective tool that is appropriate on top is a rather current and ongoing one. In so many other words, Dorlin here opens up the idea that the creation of a safe space always implies a hostile "outside" or other space. Further, Dorling sees as problematic that safe spaces will often experience problematic situations when trying to self-govern. The line of thought here is that safe spaces often explicitly reject the authority of traditional state bodies, since those exactly are identified as the oppressive force. This is problematic because then the community inside the safe space has to recreate social norms from scratch and qua definition of a safe space end up being much more restrictive and monitoring, tapping also into potentially extreme measurements for "enforcing" safety. Dorlin notes that by doing this, societal oppressive norms can end up becoming reproduced through the very instance created to shelter from it. I think this opens up 2 points worth discussing: Are there limits to the self-governance of leftist groups? How can self-governance be made possible without recreating some hierarchy or other? Does this ignore that safe spaces can sometimes be essential for survival? According to Dorlin, the alternative seems to be to instead of building sheltered, isolated safe spaces, the fight has to occur in the public, transforming the entire space without the necessity for exclusive logic. How can we argue this? Could there be an oppressed position from whence any aggressive stance towards the public forbids itself? (I think there is!) For me this seems like putting the entire burden of transformational potential on the oppressed individual, enabling a position like: "Well, the person did not object or introduce change, so the person implied consent." Will a public fight cause more harm being fought than it will save after introducing change? And who are we to calculate this beforehand?

On Fricker: Epistemic Injustice
Anmerkung
Source Text: Fricker, Miranda. Epistemic injustice: Power and the ethics of knowing. Oxford University Press, 2007. Publication
Worin unterscheiden sich inferentialistische von nicht-inferentialistischen Theorien der testimonialen Erkenntnis (d.h. des Wissens durch das Zeugniss andere)?
Inferentialistische Theorien gehen davon aus, dass die eigentliche Inferenz, also die Generierung eines neuen Epistems im Subjekt stattfindet. Konkret heisst dass, dass Ich die Aussage P einer dritten Person erst in irgendeiner Weise vor mir selbst rechtfertigen muss, bevor ich sie selbst verwenden kann. Ist die Aussage nun 2 + 2 = 4, muss ich also mit allen mir zur Verfügung stehenden Mitteln selbst überprüfen, ob diese Aussage Wahrheits- und Kohärenzkriterien erfüllt. Ich muss also beispielsweise über darunterliegende Axiome, die mir bekannt sind, die Aussage extern (ausserhalb von Person X hat das gesagt, also kann Ich das glauben) überprüfen. Im simplen Beispiel also konkret das Ergebnis berechnen. Wenn man so will, liegt also immer die “Beweislast” für meine eigenen Episteme bei mir und ich kann diesen Beweisaufwand nur begrenzt auslagern. Eine sehr direkte Folge davon wäre, dass jeglicher Erkenntnisgewinn mit erheblicher, bewusster oder unbewusster Arbeit verbunden ist. Dies wäre die wahrscheinlich logisch stringentere Theorie, gegen sie spricht aber die Phänomenologie eines Erkenntisgewinns. Eine Erkenntnis kommt uns oft vor wie ein “Heureka” Moment, wir “finden” sie, plötzlich ist sie da und wir können mit ihr arbeiten. Eine nicht-inferentialistische Theorie legt ebendiese Beweislast nicht im Subjekt an, ich habe eine Erlaubnis, oder besser, ein Recht auf a-priori Annahme der Richtigkeit der Aussage. “Person X hat mir P gesagt, also kann ich P verwenden” ist nun valide und bedarf erstmal keiner weiteren Überprüfung auf Richtigkeit. Diese Argumentationslinie ist deutlich kompatibler mit der phänomenologischen Erfahrung einer Erkenntnis vim Alltag. Wir stoßen aber auf deutlich größere Probleme, wenn wir uns fragen, woher eigentlich unser Recht auf Wahrheitsannahme von Drittaussagen kommt. Klar, 2+2=4, weil der Prof das an die Tafel geschrieben hat, ist die “schlechtere” Begründung als zu sagen, dass das Ergebnis aus gewissen mathematischen Axiomen deduziert wurde.
Formulieren Sie jeweils einen Einwand gegen beide Theorien.
Wir befinden uns also nun in der Spannung der phänomenalistischen “Heureka” Erfahrung des Findens von Epistemen (in nicht-inferentiellen Systemen) und dem Problem der schwachen Justifizierung von Aussagen gegenüber der erhöhten Stringenz eines epistemischen Systems, dass externe (logische, probabilistische, normative etc.) Gründe für Aussagen zur Verfügung stellt, aber einen schier unüberwindbaren rechnerischen Aufwand darstellt. Auch das Problem der ersten Begründung bleibt bestehen. Angenommen, ich weiß noch nichts, habe bisher null Episteme gesammelt, wie wird das erste Epistem, das ich finde, begründbar sein?
Worin besteht doxastische Verantwortung (doxastic responsibility) nach F und Ihrer eigenen Meinung nach.
Doxastische Verantwortung ist die Verantwortung für die Begründbarkeit des eigenen Nezwerkes aus Epistemen. Wenn mich also jemand fragt: Warum glaubst du das?, ist es sozial im Allgemeinen erwartbar, dass ich darauf eine Antwort liefern kann. Und wie wir eben schon am Beispiel der Begründung für 2+2=4 gesehen haben, scheint es hier “bessere” und weniger gute Gründe zu geben, das heisst, eine Person kann zur Verantwortung gezogen werden, unzureichend begründete Episteme fallen zu lassen und eine gewisse Grenze zu ziehen, eine mindest erwartbare Begründung. Diese kann sehr wahrscheinlich nicht universell formuliert werden. Eine Regel wie: Alle Bürger dürfen nur noch Aussagen weiterverwenden, denen sie eine mindestens 90-prozentige Wahrheitswarscheinlichkeit attestieren, ist aus diversen Gründen problematisch. Frickers Auffassung Doxastischer Verantwortung ist insofern speziell, als dass sie eine deutliche Verbindung moralischer Verantwortung (die wir offensichtlich alle in irgendeiner Form tragen) und Doxastischer Verantwortung sieht. Sogar die Gründe sind oft überlappend. Eine Gute Moralische Begründung, die zum Beispiel der Wahrhaftigkeit, scheint ganz offensichtlich auch eine gute doxastische begründung zu sein. Diese Parallelität zieht Fricker heran, um neo-aristotelianische Moralbegründuungen auch auf epistemischer Ebene wirksam zu machen. Ich lasse mich da gern Überzeugen von Ihr und erache es als sinnvoll Doxastische Verantwortung in gewisser Weise moralisch bindend zu machen. Intuitiv wissen wir ja auch, dass unsere Erwartung, dass dritte wahrhaftig mit uns interagieren, auf Gegenseitigkeit beruht und das leben nicht nur normativ, sondern auch auf epistemischer Ebene “verbessert”. Dies liefert auch eine recht simplistesche Rechtfertigung, annehmen zu können, dass Dritte mir die Wahreit sagen. Ich tue ja auch immer mein Bestes, warum also die anderen nicht?

-Übersetzung: Plastic Recycling - Aron Petau
Being involved with 3D Printers, there is the issue of sustainability that I am confronted with regularly. Most 3D printed parts never get recycled and add to the global waste problem, rather than reducing it. The printer most certainly doesn’t care what it is printing, the main problem is the dimensional accuracy and the purity of the material. All of this leads to a huge industry, Germany being especially involved, using loads of virgin plastic.
What can be done about it? We can design our products to last longer, we can also print recycling labels on them so they do not have to get burned after their first life. We can take care to only print functional objects, not just fun toys nobody uses. Yet, none of that prevents the use of virgin plastics. If you buy a spool of filament, there are some recycled options, but usually at twice the price at worse quality. No wonder recycled filament fails to convince the masses. It is mostly a fun thing YouTubers can pursue, not a valid commercial process.
In my opinion, the core problem is the nonexistent economic feasibility of a proper recycling process. Identifying the exact material of a piece of trash is a very hard problem, definitely not solved yet. So why do we mix the plastic up in the first place? There is a general willingness of people to recycle, but the system for it is missing.
The Master Plan
I want to get people to wash and separate their trash for me, which are the most expensive steps in the recycling process. There is a willingness to take the extra step, and even if just my mom collects bottle caps for me, that is more than I can realistically use up. This only really works when I am thinking in a local and decentral environment. The existing recycling facilities clearly will not be able to provide 200 different containers for 200 different types of plastic. Starting the process with clean and sorted materials, like bottle caps (HDPE) or failed prints (PET-G), I start off with an advantage. Now I have to take apart the trash into evenly sized particles. Meet:
The Shredder
We built the Precious Plastic Shredder!
With these awesome open-source drawings, I was able to cobble together my very own very dangerous plastic shredder.
After finding some way to drive this massive axis, I feed the beast and hopefully get tiny pretty uniform plastic bits that are ready to begin the cycle of life anew.
The solution for the motorization was an old and used garden shredder that still had an intact motor and wiring. We cut it in half and attached it to the shredder box.
After replacing the weak force transmission screw for an industrial coupler, we were ready to try it out. Obviously, there are still security concerns in this prototype, a proper hopper is already being made.
Nevertheless, we are confident that this shredder will be able to deal with the light sorts of plastic we are thinking of. As you can see, I am now able to produce awesome confetti but to do more with the plastic flakes I have to extrude them.
Meet the Filastruder
This is the Filastruder, designed and made by Tim Elmore, in an attempt to create the cheapest viable way to extrude plastic. The biggest cost issue is the tight industrial tolerances in thickness that have to be adhered to. This is in essence what separates good from the bad filament. The industry standard nowadays is at +-0.03mm. Hard to achieve on a DIY setup, but not unheard of. The setup, like any bigger industry equivalent, consists of a motor pressing plastic pellets through a heated screw, extruding molten plastic at the end through a nozzle, and setting the diameter. The leftmost machine is responsible for winding the filament properly onto a spool.
Here you can see the extrusion process in action.
The Filastruder is controlled by an Arduino and is highly configurable. The laser sensor visible in the video is already working, but I am missing more direct control over the diameter of the filament.
When it all really comes down to the single variable of the filament diameter responsible for the quality of my recycled project, a simple Machine Learning optimization directly jumps at me: I have a few variables like winder speed, extrusion speed, heat, and cooling intensity. These variables can be optimized on the fly for an exact diameter. This is actually roughly how virgin filament is produced, commercial facilities just manage much faster.
So far, I am aware of a few companies and academic projects attempting this process, but none of them manage to get either the quality or the price of other products available. Automatization does not just take out jobs away, I think it can also be a helpful tool, for example tackling environmental issues such as this one.
This project is very dear to my heart and I plan to investigate it further in the form of a master thesis. The realization will require many skills I am already picking up or still need to work on within the Design and Computation program. {: .notice--info}
Als 3D-Druck-Enthusiast sehe ich mich regelmäßig mit dem Thema Nachhaltigkeit konfrontiert. Die meisten 3D-gedruckten Teile werden nie recycelt und tragen eher zum globalen Müllproblem bei, als es zu reduzieren. Das Problem liegt weniger beim Drucker selbst als bei der dimensionalen Genauigkeit und der Reinheit des Materials. Dies führt zu einer riesigen Industrie, insbesondere in Deutschland, die enorme Mengen an Neukunststoff verbraucht.
Was kann man tun?
Wir können Produkte langlebiger gestalten, Recycling-Labels aufdrucken und nur funktionale Objekte drucken. Dennoch verhindert dies nicht die Nutzung von Neukunststoffen. Recycelter Filament ist oft doppelt so teuer bei schlechterer Qualität – kein Wunder, dass er kaum Verbreitung findet.
Das Kernproblem ist die fehlende wirtschaftliche Machbarkeit eines echten Recyclings. Das exakte Identifizieren von Kunststoffarten ist extrem schwierig und noch ungelöst. Es gibt Bereitschaft zu recyceln, aber das System fehlt.
Der Masterplan
Ich möchte Menschen motivieren, ihren Müll zu waschen und zu sortieren, die teuersten Schritte im Recyclingprozess. Selbst kleine Beiträge, wie meine Mutter, die Flaschendeckel sammelt, sind wertvoll. Dies funktioniert nur in einem lokalen, dezentralen Umfeld. Existierende Recyclinganlagen können nicht 200 verschiedene Kunststoffarten trennen.
Mit sauberem, sortiertem Material – etwa Flaschendeckel (HDPE) oder fehlerhafte Drucke (PET-G) – starte ich bereits im Vorteil. Jetzt müssen die Teile noch in gleichmäßige Partikel zerkleinert werden.
Der Shredder
Wir bauten den Precious Plastic Shredder!
Mit diesen Open-Source-Zeichnungen konnte ich meinen eigenen, sehr gefährlichen Kunststoff-Shredder zusammenbauen. Die Motorisierung übernahm ein alter Gartenschredder, der Motor und Verkabelung intakt hatte. Wir schnitten ihn auseinander und befestigten ihn am Shredder.
Nach Austausch der schwachen Kraftübertragungsschraube gegen einen Industrie-Kuppler waren wir startklar. Sicherheit bleibt ein Thema, ein richtiger Trichter ist in Arbeit.
Der Filastruder
Der Filastruder, entworfen von Tim Elmore, bietet eine kostengünstige Möglichkeit, Filament zu extrudieren. Die größten Herausforderungen: präzise Durchmesserkontrolle ±0,03 mm, sonst schwankt die Qualität.
Motor presst Kunststoffpellets durch eine beheizte Schraube, am Ende wird durch die Düse extrudiert und der Durchmesser eingestellt. Links wickelt die Maschine das Filament auf eine Spule.
Der Filastruder wird von einem Arduino gesteuert und ist hoch konfigurierbar. Ein Lasersensor misst den Filamentdurchmesser.
Machine Learning für optimale Filamentqualität
Wichtige Variablen: Wickelgeschwindigkeit, Extrusionsgeschwindigkeit, Temperatur, Kühlung. Diese Variablen können in Echtzeit optimiert werden – ähnlich wie in kommerziellen Anlagen.
Automatisierung ist nicht nur ein Jobkiller, sondern kann Umweltprobleme lösen.
Dieses Projekt liegt mir sehr am Herzen und wird Teil meiner Masterarbeit sein. Die Umsetzung erfordert viele Skills, die ich im Design & Computation Programm lerne oder noch vertiefe.

Klar, 2+2=4, weil der Prof das an die Tafel geschrieben hat, ist die “schlechtere” Begründung als zu sagen, dass das Ergebnis aus gewissen mathematischen Axiomen deduziert wurde.
Formulieren Sie jeweils einen Einwand gegen beide Theorien.
Wir befinden uns also nun in der Spannung der phänomenalistischen “Heureka” Erfahrung des Findens von Epistemen (in nicht-inferentiellen Systemen) und dem Problem der schwachen Justifizierung von Aussagen gegenüber der erhöhten Stringenz eines epistemischen Systems, dass externe (logische, probabilistische, normative etc.) Gründe für Aussagen zur Verfügung stellt, aber einen schier unüberwindbaren rechnerischen Aufwand darstellt. Auch das Problem der ersten Begründung bleibt bestehen. Angenommen, ich weiß noch nichts, habe bisher null Episteme gesammelt, wie wird das erste Epistem, das ich finde, begründbar sein?
Worin besteht doxastische Verantwortung (doxastic responsibility) nach F und Ihrer eigenen Meinung nach.
Doxastische Verantwortung ist die Verantwortung für die Begründbarkeit des eigenen Nezwerkes aus Epistemen. Wenn mich also jemand fragt: Warum glaubst du das?, ist es sozial im Allgemeinen erwartbar, dass ich darauf eine Antwort liefern kann. Und wie wir eben schon am Beispiel der Begründung für 2+2=4 gesehen haben, scheint es hier “bessere” und weniger gute Gründe zu geben, das heisst, eine Person kann zur Verantwortung gezogen werden, unzureichend begründete Episteme fallen zu lassen und eine gewisse Grenze zu ziehen, eine mindest erwartbare Begründung. Diese kann sehr wahrscheinlich nicht universell formuliert werden. Eine Regel wie: Alle Bürger dürfen nur noch Aussagen weiterverwenden, denen sie eine mindestens 90-prozentige Wahrheitswarscheinlichkeit attestieren, ist aus diversen Gründen problematisch. Frickers Auffassung Doxastischer Verantwortung ist insofern speziell, als dass sie eine deutliche Verbindung moralischer Verantwortung (die wir offensichtlich alle in irgendeiner Form tragen) und Doxastischer Verantwortung sieht. Sogar die Gründe sind oft überlappend. Eine Gute Moralische Begründung, die zum Beispiel der Wahrhaftigkeit, scheint ganz offensichtlich auch eine gute doxastische begründung zu sein. Diese Parallelität zieht Fricker heran, um neo-aristotelianische Moralbegründuungen auch auf epistemischer Ebene wirksam zu machen. Ich lasse mich da gern Überzeugen von Ihr und erache es als sinnvoll Doxastische Verantwortung in gewisser Weise moralisch bindend zu machen. Intuitiv wissen wir ja auch, dass unsere Erwartung, dass dritte wahrhaftig mit uns interagieren, auf Gegenseitigkeit beruht und das leben nicht nur normativ, sondern auch auf epistemischer Ebene “verbessert”. Dies liefert auch eine recht simplistesche Rechtfertigung, annehmen zu können, dass Dritte mir die Wahreit sagen. Ich tue ja auch immer mein Bestes, warum also die anderen nicht?

Emails are a wondrous thing and I spend the last weeks digging a bit deeper in how they actually work. Some people consider them the last domain of the decentralized dream the internet once had and that is now popping up again with federation and peer-to-peer networks as quite popular buzzwords.
We often forget that email is already a federated system and that it is likely the most important one we have. It is the only way to communicate with people that do not use the same service as you do. It has open standards and is not controlled by a single entity. Going without emails is unimaginable in today's world, yet most providers are the familiar few from the silicon valley. And really, who wants their entire decentralized, federated, peer-to-peer network to be controlled by a schmuck from the silicon valley? Mails used to be more than that and they can still be. Arguably, the world of messanging has gotten quite complex since emails popped up and there are more anti-spam AI tools that I would care to count. But the core of it is still the same and it is still a federated system. Yet, also with Emails, Capitalism has held many victories, and today many emails that are sent from a provider that does not belong to the 5 or so big names are likely to be marked as spam. This is a problem that is not easily solved, but it is a problem that is worth solving.
Another issue with emails is security, as it is somehow collectively agreed upon that emails are a valid way to communicate business informations, while Whatsapp and Signal are not. These, at least when talking about messaging services with end-to-end encryption, are likely to be way more secure than emails.
The story
So it came to pass, that I, as the only one in the family interested in operating it, "inherited" the family domain petau.net. All of our emails run through this service, that was previously managed by a web developer that was not interested in the domjobain anymore.
With lots of really secure Mail Providers like Protonmail or Tutanota, I went on a research spree, as to how I would like to manage my own service. Soon noticing that secure emails virtually always come with a price or with lacking interoperability with clients like Thunderbird or Outlook, I decided to go for migadu, a swiss provider that offers a good balance between security and usability. They also offer a student tier, which is a big plus.
While self-hosting seems like a great idea from a privacy perspective, it is also quite risky for a service that is usually the only way for any service to recover your password or your online identity. Migadu it was then, and in the last three months of basically set it and forget it, i am proud to at least have a decently granular control over my emails and can consciously reflect on the server location of The skeleton service service that enables virtually my entire online existence.
I certainly crave more open protocols in my life and am also findable on Mastodon, a microblogging network around the ActivityPub Protocol.

3D-Druck ist für mich mehr als nur ein Hobby
Darin sehe ich gesellschaftliche Veränderungen, die Demokratisierung der Produktion und kreative Möglichkeiten. Kunststoff muss nicht eines unserer größten Umweltprobleme sein, wenn wir nur unsere Perspektive und unser Verhalten ihm gegenüber ändern. Das Spritzgießen von Kunststoff war eine der Hauptantriebsfedern für das kapitalistische System, in dem wir uns heute befinden. 3D-Druck kann genutzt werden, um der Massenproduktion entgegenzuwirken. Heute wird das Schlagwort 3D-Druck bereits mit problematischen gesellschaftlichen Praktiken verbunden, es wird mit „Automatisierung“ und „On-Demand-Wirtschaft“ assoziiert. Die Technologie hat viele Aspekte, die bedacht und bewertet werden müssen, und als Technologie entstehen dadurch viele großartige Dinge, gleichzeitig befeuert sie Entwicklungen, die ich problematisch finde. Aufgrund einer Geschichte von Patenten, die die Entwicklung der Technologie beeinflussten, und einer eifrigen Übernahme durch Unternehmen, die ihre Produktionsprozesse und Margen optimieren wollen, aber auch einer sehr aktiven Hobby-Community, werden alle möglichen Projekte realisiert. Obwohl gesellschaftlich sicher explosiv, spricht viel für den 3D-Druck.
3D-Druck bedeutet lokale und individuelle Produktion. Ich glaube zwar nicht an das ganze „Jeder Haushalt wird bald eine Maschine haben, die auf Knopfdruck druckt, was gerade gebraucht wird“, sehe aber enormes Potenzial im 3D-Druck. Deshalb möchte ich meine Zukunft darauf aufbauen. Ich möchte Dinge entwerfen und sie Wirklichkeit werden lassen. Ein 3D-Drucker erlaubt mir, diesen Prozess von Anfang bis Ende zu kontrollieren. Es reicht nicht, etwas im CAD zu designen, ich muss auch die Maschine, die mein Objekt herstellt, vollständig verstehen und steuern können.
Ich benutze seit Anfang 2018 einen 3D-Drucker und mittlerweile habe ich zwei, die meistens das machen, was ich ihnen sage. Beide habe ich aus Bausätzen zusammengebaut und stark modifiziert. Ich steuere sie via Octoprint, eine Software, die mit ihrer offenen und hilfsbereiten Community mich stolz macht, sie zu nutzen, und die mich viel über Open-Source-Prinzipien gelehrt hat. 3D-Druck im Hobbybereich ist ein positives Beispiel, bei dem eine Methode mein Design beeinflusst und ich alle Bereiche liebe, die ich dadurch kennengelernt habe.

Es gab großartige Projekte mit Keramik und Druck, denen ich definitiv näher auf den Grund gehen will. Ein Projekt, das ich hervorheben möchte, sind die „evolving cups“, die mich sehr beeindruckt haben.
Diese Gruppe aus den Niederlanden generiert algorithmisch Formen von Bechern und druckt sie dann mit einem Paste-Extruder aus Ton. Der Prozess wird hier genauer beschrieben:
Der Künstler Tom Dijkstra entwickelt einen Paste-Extruder, der an einen konventionellen Drucker angebaut werden kann. Ich würde sehr gerne meine eigene Version entwickeln und mit dem Drucken neuer und alter Materialien in so einem Konzeptdrucker experimentieren.
Auch im Hinblick auf das Recycling Projekt könnte es sinnvoll sein, mehrere Maschinen in eine zu integrieren und den Drucker direkt Pellets oder Paste verarbeiten zu lassen. Ich freue mich darauf, meinen Horizont hier zu erweitern und zu sehen, was möglich ist.
Becher und Geschirr sind natürlich nur ein Beispielbereich, wo ein Rückgriff auf traditionelle Materialien innerhalb moderner Fertigung sinnvoll sein kann. Es wird auch immer mehr über 3D-gedruckte Häuser aus Ton oder Erde gesprochen, ein Bereich, in dem ich WASP sehr schätze. Sie haben mehrere Konzeptgebäude und Strukturen aus lokal gemischter Erde gebaut und beeindruckende umweltbewusste Bauwerke geschaffen.
Die Prinzipien des lokalen Bauens mit lokal verfügbaren Materialien einzuhalten und das berüchtigte Emissionsproblem in der Bauindustrie zu berücksichtigen, bringt mehrere Vorteile. Und da solche alternativen Lösungen wahrscheinlich nicht von der Industrie selbst kommen, sind Kunstprojekte und öffentliche Demonstrationen wichtige Wege, diese Lösungen zu erforschen und voranzutreiben.
Ich möchte all diese Bereiche erkunden und schauen, wie Fertigung und Nachhaltigkeit zusammenkommen und dauerhafte Lösungen für die Gesellschaft schaffen können.

-Übersetzung: Ruminations - Aron Petau
Übersetzung: Ruminations
Von Aron Petau und Niels Gercama • 2 Minuten gelesen •
was a contemplation on data privacy at Amazon. It asks how to subvert browser fingerprinting and evading the omnipresent tracking of the consumer.
The initial idea was to somehow, by interacting with the perpetrator and letting data accumulate that would degrade their knowledge and thereby destroy predictablity, making this particular dataset worth less.
We could have just added a random clickbot, to confuse things a bit and make the data less valuable. But looking at todays state of datacleanup algorithms and the sheer amount of data that is collected, this would have been a futile attempt. Amazon just detects and removes any noise we add and continues to use the data.
So, then, how can we create coherent, non-random data that is still not predictable?
One answer that this concept should demonstrate, is by inserting patterns that amazon cannot foresee with their current algorithms. As if they were trying to predict the actions of a person with shizophrenia.
The Concept
It consists of a browser extension (currently Chrome only) that overlays all web pages of Amazon with a moving entity that tracks your behavior. While tracking, an image classifier algorithm is used to formulate a product query off of the Storefront. After computation, a perfectly fitting product is displayed for your consumer's pleasure.
The analogue watchdog
A second part of the project is a low-tech installation consisting of a camera (we used a smartphone) running a computer-vision algorithm tracking tiny movements. This was then pointed towards the browser console in the laptop running the extension. The camera was then connected to a screen that displayed the captured image. The watchdog was trained to make robot noises depending on the type and amount of movement detected. Effectively, whenever data traffic beween amazon and the browser was detected, the watchdog would start making noises.
The Browser extension

Subvert a bit yourself, or just have a look at the code.
A radio atmospheric signal or sferic (sometimes also spelled "spheric") is a broadband electromagnetic impulse that occurs as a result of natural atmospheric lightning discharges. Sferics may propagate from their lightning source without major attenuation in the Earth–ionosphere waveguide, and can be received thousands of kilometres from their source.
Microsferics is a nice reference Project, which is a network of Sferics antennas, which are used to detect lightning strikes. Through triangulation not unlike the Maths happening in GPS, the (more or less) exact location of the strike can be determined. This is useful for weather prediction, but also for the detection of forest fires, which are often caused by lightning strikes.
Because the Frequency of the Sferics is, when converted to audio, still in the audible range, it is possible to listen to the strikes. This usually sounds a bit like a crackling noise, but can also be quite melodic. I was a bit reminded by a Geiger Counter.
Sferics are in the VLF (Very Low Frequency) range, sitting roughly at 10kHz, which is a bit of a problem for most radios, as they are not designed to pick up such low frequencies. This is why we built our own antenna. At 10kHz, we are talking about insanely large waves. a single wavelength there is roughly 30 Kilometers. This is why the antenna needs to be quite large. A special property of waves this large is, that they get easily reflected by the Ionosphere and the Earth's surface. Effectively, a wave like this can bounce around the globe several times before it is absorbed by the ground. This is why we can pick up Sferics from all over the world and even listen to Australian Lightning strikes. Of course, without the maths, we cannot attribute directions, but the so called "Tweeks" we picked up, usually come from at least 2000km distance.
The Build
We built several so-called "Long-Loop" antennas, which are essentially a coil of wire with a capacitor at the end. Further, a specific balun is needed, depending on the length of the wire. this can then directly output an electric signal on an XLR cable.
Loosely based on instructions from Calvin R. Graf, We built a 26m long antenna, looped several times around a wooden frame.
The Result
We have several hour-long recordings of the Sferics, which we are currently investigating for further potential.
Have a listen to a recording of the Sferics here:
As you can hear, there is quite a bit of 60 hz ground buzz in the recording. This is either due to the fact that the antenna was not properly grounded or we simply were still too close to the bustling city. I think it is already surprising that we got such a clear impression so close to Berlin. Let's see what we can get in the countryside!

-Übersetzung: Stable Dreamfusion - Aron Petau
I forked a really popular implementation that reverse engineered the Google Dreamfusion algorithm. This algorithm is closed-source and not publicly available. The implementation I forked is here This one is running on stable-diffusion as a bas process, which means we are are expected to have worse results than google. The original implementation is here
Gradio
The reason i forked the code is so that i could implement my own gradio interface for the algorithm. Gradio is a great tool for quickly building interfaces for machine learning models. No code involves, any user can state their wish, and the mechanism will spit out a ready-to-be-rigged model (obj file)
Mixamo
I used Mixamo to rig the model. It is a great tool for rigging and animating models. But before everything, it is simple. as long as you have a model with a decent humanoid shape in something of a t-pose, you can rig it in seconds. Thats exactly what i did here.
Unity
I used Unity to render the model to the magic leap 1. Through this, i could create an interactive and immersive environment with the generated models.
The dream was, to build a AI- Chamber of wishes. You pick up the glasses, state your desires and then the algorithm will present to you an almost-real object in AR.
Due to not having access to the proprietary sources from google and the beefy, but still not quite machine-learning ready computers we have at the studio, the results are not quite as good as i hoped. But still, the results are quite interesting and i am happy with the outcome. A single generated object in the Box takes roughly 20 minutes to generate. Even then, the algorithm is quite particular and oftentimes will not generate anything coherent at all.

-switching from jekyll to zola - Aron Petau
switching from jekyll to zola
Von Aron Petau und Friedrich Weber • 4 Minuten gelesen •
For applying to my master's program in 2020, a portfolio was required, and since it was more or less for a design program, I wanted to have a nice website. After trying for a month to get what I wanted out of WordPress, and angrily quitting multiple times, I discovered Jekyll. Back then, Hugo and 11ty were the newer kids on the block, but I was heavily relying on the free hosting from GitHub Pages, where Jekyll was the easiest to integrate.
Back then, looking for inspiration, I had an ethics professor I really liked, and he had a Jekyll site with the Minimal Mistakes theme. Prof. Mühlhoff
I went about using Minimal Mistakes, and it was a great experience. The resulting portfolio at least got me into the master's, and I fell in love with the general idea of being able to write sites in markdown, while a program would take care of the rest.
For years, Jekyll was my go-to for building static websites. It was familiar, widely supported, and part of the broader Ruby ecosystem. But over time, my frustrations grew—slow builds, complicated plugin setups, and a dependency stack that never felt quite right. To be honest, many of the drawbacks were totally not Jekyll’s fault. It was just slow, otherwise fine. But especially using GitHub Pages imposed quite a few limitations on plugins and themes. Also, maybe I didn’t put in enough effort, but I could never really get theme modifications working. Just extending the theme to show multiple authors was a pain—although it was eventually working.
On now finishing the master's, I wanted a visual overhaul, and while browsing for inspiration again, using Jekyll at all got questioned again. I knew I wanted a static site generator, because markdown is the shit. So after looking around further, Zola emerged—actually through a chatbot suggestion 😄
Recently, I made the leap to Zola, a Rust-powered static site generator, and I don't see myself going back.
rust feels right
I’ve always admired Rust for its speed, safety, and modern tooling. Using a static site generator built with Rust just made sense. Zola is fast—blazing fast. Even during local development, rebuilds are near-instant, and that alone makes the writing process smoother and more enjoyable.
Plus, using something written in Rust means fewer external dependencies, no bundler hell, and zero Ruby setup headaches. I can just download the binary, run it, and get going. It respects my time.
zola is thoughtfully designed
Beyond performance, Zola is just really well designed. Its template syntax (thanks to Tera) is more powerful and readable than Liquid. The built-in shortcodes, pagination, and asset pipelines all feel cohesive and purposeful. There’s very little “configuration over convention” fatigue that Jekyll often gave me.
And even though both systems are markdown-based, migrating wasn’t just a matter of copy-pasting files. I had to rethink frontmatter, adjust templates, and wrangle image paths and shortcodes. The structure and behavior are different enough that it felt like a real rebuild—not just a port.
duckquill made me switch
The real catalyst, though? Duckquill, a stunning Zola theme built by Daudix. It struck the perfect balance between minimalism and elegance—exactly the aesthetic I wanted but could never quite achieve with Jekyll. Duckquill didn’t just make Zola usable for me; it made it irresistible.
What really sets Duckquill apart—beyond its clean typography and smart layout—is how well it supports a vision of digital autonomy. The theme comes with Mastodon-powered comments, allowing for lightweight, federated interaction without relying on big centralized platforms. This fits perfectly with my goal of reclaiming control through self-hosting. Whether it's running my own site, owning my content, or interacting through the fediverse, Duckquill reinforces those values rather than working against them. It’s a rare example of design and infrastructure aligning with personal principles.
final thoughts
Switching from Jekyll to Zola wasn’t effortless, but it was absolutely worth it. I now have a faster, more reliable, and better-looking site that’s easier to maintain and feels like it fits my tooling philosophy.
If you're feeling the weight of your current setup, maybe it's time to try Zola—and give Duckquill a spin while you're at it.

-<p>As you can see, the design faces some questionable choices, but all mechanics are homemade from the ground up and I learned a lot. I often struggle to enjoy competitive games and think there is potential in a co-dependent game interface.

-<p>As you can perhaps see, the ball-rolling navigation is quite hard to use.
-It is a purely physics-based system, where, depending on the materiality of the ball, its weight, and therefore its inertia will drastically change.</p>
-<p>On small screens, the prototype version of the game is virtually impossible to control and several visual bugs within the viewport still obfuscate items when they are too close. Considering that virtually all the mechanics are written from scratch, with a follow-me camera, collision detection, smart moving agents, and a still very wonky-looking grappling gun, I still think it deserves a spot in this portfolio.
-For this project I focused completely on the mechanics of the game, resulting in lots of used prefabs and readymade 3D Objects. Next time, I want to do that myself too.</p>
-<p>I enjoyed my stint into Unity a lot and am looking forward to creating my first VR application and would love to try out some form of mechanics where the user vision is completely obfuscated by VR and they have to carry their eyes as a handheld connected camera so that the players can move around the camera itself with their hands.</p>

- <h2 id="2020:_discovering_jekyll">2020: discovering jekyll</h2>
-<p>For applying to my master's program in 2020, a portfolio was required, and since it was more or less for a design program, I wanted to have a nice website.
-After trying for a month to get what I wanted out of WordPress, and angrily quitting multiple times, I discovered <a href="https://jekyllrb.com">Jekyll</a>.
-Back then, <a href="https://gohugo.io">Hugo</a> and <a href="https://www.11ty.dev">11ty</a> were the newer kids on the block, but I was heavily relying on the free hosting from <a href="https://pages.github.com">GitHub Pages</a>, where Jekyll was the easiest to integrate.</p>
-<p>Back then, looking for inspiration, I had an ethics professor I really liked, and he had a Jekyll site with the <a href="https://mmistakes.github.io/minimal-mistakes/">Minimal Mistakes</a> theme.
-<a href="https://rainermuehlhoff.de">Prof. Mühlhoff</a></p>
-<p>I went about using Minimal Mistakes, and it was a great experience.
-The resulting portfolio at least got me into the master's, and I fell in love with the general idea of being able to write sites in markdown, while a program would take care of the rest.</p>
-<p>For years, Jekyll was my go-to for building static websites.
-It was familiar, widely supported, and part of the broader Ruby ecosystem.
-But over time, my frustrations grew—slow builds, complicated plugin setups, and a dependency stack that never felt quite right.
-To be honest, many of the drawbacks were totally not Jekyll’s fault. It was just slow, otherwise fine. But especially using GitHub Pages imposed quite a few limitations on plugins and themes.
-Also, maybe I didn’t put in enough effort, but I could never really get theme modifications working. Just extending the theme to show multiple authors was a pain—although it was eventually working.</p>
-<p>On now finishing the master's, I wanted a visual overhaul, and while browsing for inspiration again, using Jekyll at all got questioned again.
-I knew I wanted a static site generator, because markdown is the shit.
-So after looking around further, <strong><a href="https://www.getzola.org/">Zola</a></strong> emerged—actually through a chatbot suggestion 😄</p>
-<p>Recently, I made the leap to Zola, a Rust-powered static site generator, and I don't see myself going back.</p>
-<hr />
-<h2 id="rust_feels_right">rust feels right</h2>
-<p>I’ve always admired <a href="https://www.rust-lang.org/">Rust</a> for its speed, safety, and modern tooling.
-Using a static site generator built with Rust just made sense. <strong>Zola is fast</strong>—blazing fast.
-Even during local development, rebuilds are near-instant, and that alone makes the writing process smoother and more enjoyable.</p>
-<p>Plus, using something written in Rust means fewer external dependencies, no bundler hell, and zero Ruby setup headaches.
-I can just download the binary, run it, and get going. It respects my time.</p>
-<hr />
-<h2 id="zola_is_thoughtfully_designed">zola is thoughtfully designed</h2>
-<p>Beyond performance, Zola is just really well designed.
-Its template syntax (thanks to <a href="https://tera.netlify.app">Tera</a>) is more powerful and readable than Liquid.
-The built-in shortcodes, pagination, and asset pipelines all feel cohesive and purposeful.
-There’s very little “configuration over convention” fatigue that Jekyll often gave me.</p>
-<p>And even though both systems are markdown-based, migrating wasn’t just a matter of copy-pasting files.
-I had to rethink frontmatter, adjust templates, and wrangle image paths and shortcodes.
-The structure and behavior are different enough that it felt like a real rebuild—not just a port.</p>
-<hr />
-<h2 id="duckquill_made_me_switch">duckquill made me switch</h2>
-<p>The real catalyst, though? <a href="https://github.com/daudix/duckquill"><strong>Duckquill</strong></a>, a stunning Zola theme built by <a href="https://github.com/daudix">Daudix</a>.
-It struck the perfect balance between minimalism and elegance—exactly the aesthetic I wanted but could never quite achieve with Jekyll.
-Duckquill didn’t just make Zola usable for me; it made it <em>irresistible</em>.</p>
-<p>What really sets <strong>Duckquill</strong> apart—beyond its clean typography and smart layout—is how well it supports a vision of digital autonomy.
-The theme comes with <strong>Mastodon-powered comments</strong>, allowing for lightweight, federated interaction without relying on big centralized platforms.
-This fits perfectly with my goal of reclaiming control through <strong>self-hosting</strong>.
-Whether it's running my own site, owning my content, or interacting through the fediverse, Duckquill reinforces those values rather than working against them.
-It’s a rare example of design and infrastructure aligning with personal principles.</p>
-<hr />
-<h2 id="final_thoughts">final thoughts</h2>
-<p>Switching from Jekyll to Zola wasn’t effortless, but it was absolutely worth it.
-I now have a faster, more reliable, and better-looking site that’s easier to maintain and feels like it fits my tooling philosophy.</p>
-<p>If you're feeling the weight of your current setup, maybe it's time to try Zola—and give Duckquill a spin while you're at it.</p>

- <p>Being involved with 3D Printers, there is the issue of sustainability that I am confronted with regularly.
-Most 3D printed parts never get recycled and add to the global waste problem, rather than reducing it.
-The printer most certainly doesn’t care what it is printing, the main problem is the dimensional accuracy and the purity of the material. All of this leads to a huge industry, Germany being especially involved, using loads of virgin plastic.</p>
-<p>What can be done about it?
-We can design our products to last longer, we can also print recycling labels on them so they do not have to get burned after their first life. We can take care to only print functional objects, not just fun toys nobody uses.
-Yet, none of that prevents the use of virgin plastics. If you buy a spool of filament, there are some recycled options, but usually at twice the price at worse quality. No wonder recycled filament fails to convince the masses. It is mostly a fun thing YouTubers can pursue, not a valid commercial process.</p>
+ <p>Als 3D-Druck-Enthusiast sehe ich mich regelmäßig mit dem Thema Nachhaltigkeit konfrontiert.<br />
+Die meisten 3D-gedruckten Teile werden nie recycelt und tragen eher zum globalen Müllproblem bei, als es zu reduzieren.<br />
+Das Problem liegt weniger beim Drucker selbst als bei der <strong>dimensionalen Genauigkeit</strong> und der <strong>Reinheit des Materials</strong>. Dies führt zu einer riesigen Industrie, insbesondere in Deutschland, die enorme Mengen an <strong>Neukunststoff</strong> verbraucht.</p>
+<h3 id="Was_kann_man_tun?">Was kann man tun?</h3>
+<p>Wir können Produkte langlebiger gestalten, Recycling-Labels aufdrucken und nur funktionale Objekte drucken. Dennoch verhindert dies nicht die Nutzung von Neukunststoffen. Recycelter Filament ist oft doppelt so teuer bei schlechterer Qualität – kein Wunder, dass er kaum Verbreitung findet.</p>

-<p>In my opinion, the core problem is the nonexistent economic feasibility of a proper recycling process. Identifying the exact material of a piece of trash is a very hard problem, definitely not solved yet. So why do we mix the plastic up in the first place? There is a general willingness of people to recycle, but the system for it is missing.</p>
-<h1 id="The_Master_Plan">The Master Plan</h1>
-<p>I want to get people to wash and separate their trash for me, which are the most expensive steps in the recycling process. There is a willingness to take the extra step, and even if just my mom collects bottle caps for me, that is more than I can realistically use up.
-This only really works when I am thinking in a local and decentral environment.
-The existing recycling facilities clearly will not be able to provide 200 different containers for 200 different types of plastic.
-Starting the process with clean and sorted materials, like bottle caps (HDPE) or failed prints (PET-G), I start off with an advantage.
-Now I have to take apart the trash into evenly sized particles.

-<p>With these awesome open-source drawings, I was able to cobble together my very own very dangerous plastic shredder.</p>
-<p>After finding some way to drive this massive axis, I feed the beast and hopefully get tiny pretty uniform plastic bits that are ready to begin the cycle of life anew.</p>
-<p>The solution for the motorization was an old and used garden shredder that still had an intact motor and wiring.
-We cut it in half and attached it to the shredder box.</p>

+<p>Ich möchte Menschen motivieren, ihren Müll <strong>zu waschen und zu sortieren</strong>, die teuersten Schritte im Recyclingprozess. Selbst kleine Beiträge, wie meine Mutter, die Flaschendeckel sammelt, sind wertvoll.<br />
+Dies funktioniert nur in einem <strong>lokalen, dezentralen Umfeld</strong>. Existierende Recyclinganlagen können nicht 200 verschiedene Kunststoffarten trennen.</p>
+<p>Mit sauberem, sortiertem Material – etwa Flaschendeckel (HDPE) oder fehlerhafte Drucke (PET-G) – starte ich bereits im Vorteil. Jetzt müssen die Teile noch in <strong>gleichmäßige Partikel</strong> zerkleinert werden.</p>

+Die Motorisierung übernahm ein alter Gartenschredder, der Motor und Verkabelung intakt hatte. Wir schnitten ihn auseinander und befestigten ihn am Shredder.</p>

-<p>After replacing the weak force transmission screw for an industrial coupler, we were ready to try it out. Obviously, there are still security concerns in this prototype, a proper hopper is already being made.</p>
-<p>Nevertheless, we are confident that this shredder will be able to deal with the light sorts of plastic we are thinking of.
-As you can see, I am now able to produce awesome confetti but to do more with the plastic flakes I have to extrude them.</p>
-<h2 id="Meet_the_Filastruder">Meet the Filastruder</h2>
-<p>This is the Filastruder, designed and made by Tim Elmore, in an attempt to create the cheapest viable way to extrude plastic. The biggest cost issue is the tight industrial tolerances in thickness that have to be adhered to. This is in essence what separates good from the bad filament. The industry standard nowadays is at +-0.03mm. Hard to achieve on a DIY setup, but not unheard of. The setup, like any bigger industry equivalent, consists of a motor pressing plastic pellets through a heated screw, extruding molten plastic at the end through a nozzle, and setting the diameter. The leftmost machine is responsible for winding the filament properly onto a spool.</p>
-<p>Here you can see the extrusion process in action.</p>
+<p>Nach Austausch der schwachen Kraftübertragungsschraube gegen einen Industrie-Kuppler waren wir startklar. Sicherheit bleibt ein Thema, ein richtiger Trichter ist in Arbeit.</p>
+<h2 id="Der_Filastruder">Der Filastruder</h2>
+<p>Der <strong>Filastruder</strong>, entworfen von Tim Elmore, bietet eine kostengünstige Möglichkeit, Filament zu extrudieren.<br />
+Die größten Herausforderungen: <strong>präzise Durchmesserkontrolle</strong> ±0,03 mm, sonst schwankt die Qualität.</p>
+<p>Motor presst Kunststoffpellets durch eine beheizte Schraube, am Ende wird durch die Düse extrudiert und der Durchmesser eingestellt. Links wickelt die Maschine das Filament auf eine Spule.</p>

-<p>The Filastruder is controlled by an Arduino and is highly configurable. The laser sensor visible in the video is already working, but I am missing more direct control over the diameter of the filament.</p>
-<p>When it all really comes down to the single variable of the filament diameter responsible for the quality of my recycled project, a simple Machine Learning optimization directly jumps at me: I have a few variables like winder speed, extrusion speed, heat, and cooling intensity. These variables can be optimized on the fly for an exact diameter. This is actually roughly how virgin filament is produced, commercial facilities just manage much faster.</p>
-<p><img src="/assets/images/recycling_variables.png" alt="The variables in an iterative optimization" /></p>
-<p>So far, I am aware of a few companies and academic projects attempting this process, but none of them manage to get either the quality or the price of other products available. Automatization does not just take out jobs away, I think it can also be a helpful tool, for example tackling environmental issues such as this one.</p>
-<p>This project is very dear to my heart and I plan to investigate it further in the form of a master thesis.
-The realization will require many skills I am already picking up or still need to work on within the Design and Computation program.

-<p>While learning about 3D Printing, I was most intrigued by the possibility to modify and repair existing products. While there is an amazing community with lots of good and free models around, naturally I came to a point where I did not find what I was looking for readily designed. I realized this is an essential skill for effectively operating not just 3D Printers, but any productive machine really.</p>
-<p>Since youtube was the place I was learning all about 3D Printing, and all the people that I looked up to there were using Fusion 360 as their CAD Program that’s what I got into.
-In hindsight, that was a pretty good choice and I am in love with the abilities parametric design gives me.
-Below you will find some of my designs.
-The process is something that I enjoy a lot and wish to dive into deeper.</p>
-<p>By trial and error, I already learned a lot about designing specifically for 3D Printing, but I often feel that there are many aesthetic considerations in design that I am not familiar with.
-I want to broaden my general ability to design physical objects, which is something I hope to gain during my master’s.</p>

+<p>Beim Erlernen des 3D-Drucks hat mich vor allem die Möglichkeit fasziniert, bestehende Produkte zu verändern oder zu reparieren.<br />
+Auch wenn es eine großartige Community mit vielen guten und kostenlosen Modellen gibt, bin ich schnell an den Punkt gekommen, an dem ich nicht fand, was ich suchte.<br />
+Mir wurde klar, dass dies eine wesentliche Fähigkeit ist, um nicht nur 3D-Drucker, sondern grundsätzlich jede Art von Produktionsmaschine sinnvoll zu nutzen.</p>
+<p>Da ich alles über 3D-Druck auf YouTube gelernt habe und dort fast alle mit <strong>Fusion 360</strong> arbeiteten, habe ich mich ebenfalls dafür entschieden.<br />
+Rückblickend war das eine sehr gute Wahl – ich habe mich in die Möglichkeiten des <strong>parametrischen Designs</strong> verliebt.<br />
+Unten findest du einige meiner Entwürfe.<br />
+Der Prozess selbst macht mir unglaublich viel Spaß und ich möchte ihn noch weiter vertiefen.</p>
+<p>Durch Ausprobieren habe ich bereits viel darüber gelernt, wie man speziell für den 3D-Druck konstruiert.<br />
+Trotzdem habe ich oft das Gefühl, dass mir ein tieferes Verständnis für <strong>ästhetische Gestaltung</strong> fehlt.<br />
+Ich möchte meine generelle Fähigkeit erweitern, physische Objekte zu entwerfen – etwas, das ich mir im Masterstudium erhoffe.</p>

-<p>Besides coming up with new objects, incorporating the real world is also an interest of mine.</p>
-<h3 id="Interaction_with_real_objects_and_environments">Interaction with real objects and environments</h3>
-<p>In the last few years I have played around with a few smartphone cameras and was always quite sad, that my scans were never quite accurate enough to do cool stuff with them.
-I could not really afford real 3D scanner and had already started cobbling together a raspberry Pi camera with a cheap TOF sensor, which is a simple, but not quite as good replacement for a laser or a lidar sensor, but then Apple came out with the first phones with accessible Lidar sensor.
-Recently, through work at the university I got access to a device with a lidar sensor and started having fun with it.
-See some examples here:</p>

-<p>This last one was scanned with just my smartphone camera. You can see that the quality is notably worse, but considering is was created with just a single, run-of-the-mill smartphone sensor, I think it is still pretty impressive and will certainly do something towards democratizing such technologies and abilities.</p>

+<h3 id="Interaktion_mit_realen_Objekten_und_Umgebungen">Interaktion mit realen Objekten und Umgebungen</h3>
+<p>In den letzten Jahren habe ich mit verschiedenen Smartphone-Kameras experimentiert – leider waren meine Scans meist nicht präzise genug, um wirklich etwas damit anzufangen.<br />
+Ein professioneller 3D-Scanner war zu teuer, also bastelte ich mir eine Kombination aus einer <strong>Raspberry-Pi-Kamera</strong> und einem günstigen <strong>TOF-Sensor</strong>.<br />
+Das Setup ist simpel, aber bei weitem nicht so genau wie Laser- oder LiDAR-Sensoren. Dann brachte Apple die ersten Geräte mit <strong>zugänglichem LiDAR</strong> heraus.</p>
+<p>Durch meine Arbeit an der Universität hatte ich schließlich Zugriff auf ein Gerät mit LiDAR und begann, damit zu experimentieren.<br />
+Ein paar Beispiele siehst du hier:</p>

+<p>Der letzte Scan hier wurde nur mit einer <strong>Smartphone-Kamera</strong> erstellt.<br />
+Man erkennt deutlich, dass die Qualität geringer ist, aber angesichts der einfachen Technik finde ich das Ergebnis beeindruckend –<br />
+und es zeigt, wie sehr solche Technologien gerade <strong>demokratisiert</strong> werden.</p>

-<h2 id="Perspective">Perspective</h2>
-<p>What this section is supposed to deliver is the message that I am currently not where I want to be navigating the vast possibilities of CAD. I feel confident enough to approach small repairs around the flat with a new perspective, but I still lack technical expertise when approaching a collection composite parts, having to function together. I still have lots of projects halfdone or half-thought and one major reason is that there is no real critical exchange within my field of study.</p>
-<p>I want more than designing figurines or wearables.
-I want to incorporate 3D printing as a method to extend the abilities of other tools, have mechanical and electrical purposes, be foodsafe and engaging.
-I fell in love with the idea of designing a toy system, inspired by <a href="https://www.kickstarter.com/projects/makeway/makeway-create-intricate-courses-watch-your-marbles-soar">Makeways on Kickstarter</a>, I have already started adding my own parts to their set.</p>
-<p>I dream of my very own 3D printed coffeecup, one that is both foodsafe and dishwasher-surviving. For that, I would have to do quite a bit of material research, but that just makes the idea so much more appealing.
-I would love finding a material composition incorporating waste to stop relying on plastics, or at least on fossile plastics.
-Once in Berlin, I would want to talk to the people at <a href="https://www.kaffeeform.com/en/">Kaffeform</a> producing largely compostable Coffee Cups incorporating a significant amount of old ground espresso, albeit using injection molding for their process.
-The industry selling composite filaments is much more conservative with the percentage of non-plastic additives, because with a nozzle extrusion process there is much more to go wrong.
-Still, I would love to explore that avenue further and think there is a lot to be gained from looking at pellet printers.</p>
-<p>I also credit huge parts of my exploration process into local recycling to the awesome people at <a href="https://preciousplastic.com">Precious Plastic</a>, who I will join over the summer to learn more about their system.</p>
-<p>I find it hard to write anything about CAD without connecting it directly to a manufacturing process.
-And I believe that's a good thing. Always tying a design process to its realization, grounds the process and attaches to it some immediacy.</p>
-<p>For me to become more confident in this process, I am still missing more expertise in organic shapes, so I would be happy to dig more into Blender, an awesome tool that in my mind is far too powerful to dive into it with just youtube lessons.</p>

+<p>Was dieser Abschnitt zeigen soll: Ich bin beim Thema <strong>CAD</strong> noch nicht da, wo ich gerne wäre.<br />
+Ich fühle mich sicher genug, um kleine Reparaturen im Alltag anzugehen,<br />
+aber beim <strong>Konstruieren komplexer Bauteilgruppen</strong>, die zusammen funktionieren müssen, fehlt mir noch technisches Know-how.<br />
+Viele meiner Projekte sind halbfertig – einer der Hauptgründe ist der <strong>Mangel an fachlichem Austausch</strong> in meinem Umfeld.</p>
+<p>Ich möchte mehr als nur Figuren oder Wearables gestalten.<br />
+Ich möchte den <strong>3D-Druck als Werkzeugerweiterung</strong> nutzen –<br />
+für mechanische oder elektrische Anwendungen, lebensmittelechte Objekte, oder einfach Dinge, die begeistern.<br />
+Ich liebe die Idee, ein <strong>Baukastensystem</strong> zu entwickeln.<br />
+Inspiriert von <a href="https://www.kickstarter.com/projects/makeway/makeway-create-intricate-courses-watch-your-marbles-soar">Makeways auf Kickstarter</a> habe ich bereits angefangen, eigene Teile zu entwerfen.</p>
+<p>Ein Traum von mir ist eine <strong>eigene 3D-gedruckte Kaffeetasse</strong>, die sowohl <strong>spülmaschinenfest als auch lebensmittelecht</strong> ist.<br />
+Dafür müsste ich viel Materialforschung betreiben – aber genau das macht es spannend.<br />
+Ich möchte ein Material finden, das <strong>Abfälle</strong> einbezieht, um weniger von <strong>fossilen Kunststoffen</strong> abhängig zu sein.<br />
+In Berlin möchte ich mich mit den Leuten von <a href="https://www.kaffeeform.com/de/">Kaffeform</a> austauschen, die <strong>kompostierbare Becher</strong> aus gebrauchten Espressoresten herstellen (wenn auch per Spritzgussverfahren).</p>
+<p>Die Hersteller von <strong>Komposit-Filamenten</strong> sind bei der Beimischung nicht-plastischer Stoffe sehr vorsichtig,<br />
+weil der <strong>Extrusionsprozess</strong> durch Düsen leicht fehleranfällig ist.<br />
+Trotzdem glaube ich, dass gerade in diesem Bereich noch viel Potenzial steckt – besonders mit <strong>Pelletdruckern</strong>.</p>
+<p>Große Teile meiner Auseinandersetzung mit <strong>lokalem Recycling</strong> verdanke ich den großartigen Leuten von <a href="https://preciousplastic.com">Precious Plastic</a>, deren Open-Source-Designs mich sehr inspiriert haben.<br />
+Ich finde es schwer, über CAD zu schreiben, ohne gleichzeitig über den <strong>Herstellungsprozess</strong> zu sprechen –<br />
+und ich halte das für etwas Gutes.<br />
+Design und Umsetzung gehören für mich zusammen.</p>
+<p>Um noch sicherer zu werden, möchte ich mich stärker auf <strong>organische Formen</strong> konzentrieren.<br />
+Deshalb will ich tiefer in <strong>Blender</strong> einsteigen – ein großartiges Tool, das viel zu mächtig ist, um es nur über YouTube zu lernen.</p>

-<p>Implemented in Unity, Ballpark is a Concept work for a collaborative 2-Player Game, where one player is a navigator with a third-person perspective and another player is a copilot, responsible for interaction with the environment – featuring mostly working physics, intelligent enemies, a gun, a grappling hook system for traversing the map, a 2D Interface for navigation and a health bar system. On top of the meanest cyberpunk vibes my past self was able to conjure.</p>

-<p>As you can see, the design faces some questionable choices, but all mechanics are homemade from the ground up and I learned a lot. I often struggle to enjoy competitive games and think there is potential in a co-dependent game interface. During early testing, we often found that it enforces player communication since already the tutorial is quite hard to beat.
-Due to me being a leftie, perhaps not entirely smart, I gave player one the keyboard arrows to work with and player two the WASD keys and left and right mouse buttons for grappling and shooting. For the game, it has an interesting side effect, in that players are forced not only to interact through the differing information on each player's screen but also have to physically interact and coordinate the controls.</p>
-<p>As you can perhaps see, the ball-rolling navigation is quite hard to use.
-It is a purely physics-based system, where, depending on the materiality of the ball, its weight, and therefore its inertia will drastically change.</p>
-<p>On small screens, the prototype version of the game is virtually impossible to control and several visual bugs within the viewport still obfuscate items when they are too close. Considering that virtually all the mechanics are written from scratch, with a follow-me camera, collision detection, smart moving agents, and a still very wonky-looking grappling gun, I still think it deserves a spot in this portfolio.
-For this project I focused completely on the mechanics of the game, resulting in lots of used prefabs and readymade 3D Objects. Next time, I want to do that myself too.</p>
-<p>I enjoyed my stint into Unity a lot and am looking forward to creating my first VR application and would love to try out some form of mechanics where the user vision is completely obfuscated by VR and they have to carry their eyes as a handheld connected camera so that the players can move around the camera itself with their hands.</p>
+<p>Das Design enthält einige fragwürdige Entscheidungen, aber alle Mechaniken sind <strong>von Grund auf selbst entwickelt</strong>, und ich habe viel dabei gelernt. Ich spiele selten kompetitive Spiele, sehe aber Potenzial in einer <strong>kooperativen, voneinander abhängigen Spielmechanik</strong>. Schon das Tutorial erfordert intensive Spielerkommunikation.</p>
+<p>Als Linkshänder habe ich Spieler eins die Pfeiltasten gegeben und Spieler zwei die WASD-Tasten sowie die linken und rechten Maustasten für Schießen und Greifhaken. Das führt zu einem interessanten Nebeneffekt: Spieler müssen nicht nur über unterschiedliche Informationen auf ihren Bildschirmen kommunizieren, sondern auch ihre Steuerung physisch koordinieren.</p>
+<p>Die <strong>Ball-Navigation</strong> ist ziemlich schwer zu kontrollieren.<br />
+Es handelt sich um ein <strong>rein physikbasiertes System</strong>, bei dem Material, Gewicht und Trägheit der Kugel die Bewegung stark beeinflussen.</p>
+<p>Auf kleinen Bildschirmen ist die Steuerung praktisch unmöglich, und einige visuelle Bugs verdecken Objekte bei zu naher Ansicht. Dennoch, da fast alle Mechaniken von Grund auf programmiert wurden – inklusive Follow-Camera, Kollisionsabfrage, smarten Agenten und einem noch etwas wackeligen Greifhaken – verdient das Projekt einen Platz im Portfolio.</p>
+<p>Für dieses Projekt habe ich mich komplett auf <strong>Mechaniken</strong> konzentriert, weshalb viele fertige Prefabs und 3D-Objekte verwendet wurden. Beim nächsten Mal möchte ich diese auch selbst erstellen.</p>
+<p>Ich habe Unity sehr genossen und freue mich darauf, meine erste <strong>VR-Anwendung</strong> zu entwickeln.<br />
+Ich möchte Mechaniken ausprobieren, bei denen die Sicht des Spielers durch VR komplett blockiert wird und die Augen als <strong>tragbare, verbundene Kamera</strong> bewegt werden, sodass die Spieler die Kamera selbst physisch steuern können.</p>

-<p>I love hosting, I love experimenting in the Kitchen. Starting with homebrews was a natural fit for me and during the first wave of Covid-19, I went the whole homebrewer’s route of bottle fermentation and small batches later elevating my game with larger batches of 50 liters and a pressure tank system.</p>
-<p>Starting out, I found it fascinating, how just 4 rather simple ingredients, malt, hops, water and yeast, can form such an incredible range of taste experiences. It was and still is, a tremendous learning experience, where one slowly has to accept not being able to control the process fully and find room for creativity.</p>
-<p>Why do I present such an unrelated non-academic hobby here? I simply do not regard it as unrelated, experimenting and optimizing a process and a workflow, creating optimal conditions for the yeast to do its job feels very similar to approaching a coding project.
-Yeast and what it does fascinates me. Every time I open the latch to release some pressure on the Tank I think of the awesome symbiotic relationships yeast has with humans and how many different strains live there together to create a unique, yet tailored flavor. Several ideas are floating around of changing the brewing process by capturing the created carbon dioxide and using it productively. I could see a car tire being filled with my beer gas, or an algae farm munching away on my CO2 byproducts. Within a closed-loop pressurized system, such ideas actually become realizable and I would love to explore them further.</p>
-<p>I am not yet an expert on algae, but I can manage with yeast and I believe they can coexist and create a more sustainable cycle of production.
-Young Henrys, a brewery in Australia is already incorporating algae into its industrial process:
-<a href="https://younghenrys.com/algae">The Algae project</a></p>
-<p>Such ideas do not come into the industry by themselves: I believe that art and the exploratory discovery of novel techniques are the same things. Good and inventive design can improve society and make steps towards sustainability. I want to be part of that and would love to find new ways of using yeast in other design contexts: See whether I can make them work in a closed circular system, make them calculate things for me, or simply making my next beer taste awesome with just the right amount of fizz.</p>

+<p>Ich liebe es zu veranstalten, ich liebe es, in der Küche zu experimentieren. Mit Homebrews zu starten, war für mich eine natürliche Entscheidung, und während der ersten Covid-19-Welle habe ich den kompletten Heimbräuerweg mit Flaschenfermentation und kleinen Chargen eingeschlagen, später habe ich mein Setup auf 50-Liter-Chargen mit Drucktank-System erweitert.</p>
+<p>Zu Beginn war ich fasziniert, wie aus nur <strong>vier einfachen Zutaten</strong> – Malz, Hopfen, Wasser und Hefe – ein so unglaubliches Spektrum an Geschmackserlebnissen entstehen kann. Es war und ist immer noch ein <strong>tremendales Lernprojekt</strong>, bei dem man langsam akzeptieren muss, dass man den Prozess nicht vollständig kontrollieren kann, und gleichzeitig Raum für Kreativität findet.</p>
+<p>Warum präsentiere ich dieses scheinbar nicht-akademische Hobby hier? Ich sehe es nicht als irrelevant an: <strong>Experimentieren und Optimieren eines Prozesses und Workflows</strong>, optimale Bedingungen für die Hefe zu schaffen, fühlt sich dem Ansatz eines Programmierprojekts sehr ähnlich an.</p>
+<p>Hefe und ihre Wirkung faszinieren mich. Jedes Mal, wenn ich den Verschluss öffne, um etwas Druck aus dem Tank abzulassen, denke ich an die erstaunlichen symbiotischen Beziehungen der Hefe mit Menschen und wie viele verschiedene Stämme zusammenleben, um einen einzigartigen, maßgeschneiderten Geschmack zu erzeugen.<br />
+Es gibt einige Ideen, den Brauprozess zu verändern, indem das erzeugte CO₂ aufgefangen und produktiv genutzt wird – z. B. ein Autoreifen gefüllt mit Biergas oder eine Algenfarm, die das CO₂ aufnimmt. Innerhalb eines <strong>geschlossenen, druckbeaufschlagten Systems</strong> werden solche Ideen tatsächlich realisierbar, und ich möchte sie weiter erforschen.</p>
+<p>Ich bin noch kein Experte für Algen, aber mit Hefe komme ich klar, und ich glaube, dass sie koexistieren und einen nachhaltigeren Produktionszyklus schaffen können.<br />
+Die australische Brauerei Young Henrys integriert Algen bereits in ihren industriellen Prozess: <a href="https://younghenrys.com/algae">The Algae project</a></p>
+<p>Solche Ideen kommen nicht von selbst in die Industrie: Ich glaube, dass Kunst und die experimentelle Entdeckung neuer Techniken dasselbe sind. <strong>Gutes, erfinderisches Design</strong> kann die Gesellschaft verbessern und Schritte in Richtung Nachhaltigkeit gehen. Ich möchte daran teilhaben und neue Wege finden, Hefe in anderen Designkontexten einzusetzen: ob in einem geschlossenen Kreislaufsystem, zum Berechnen von Dingen oder einfach, um mein nächstes Bier mit der perfekten Spritzigkeit zu brauen.</p>

- <p>Being involved with 3D Printers, there is the issue of sustainability that I am confronted with regularly.
-Most 3D printed parts never get recycled and add to the global waste problem, rather than reducing it.
-The printer most certainly doesn’t care what it is printing, the main problem is the dimensional accuracy and the purity of the material. All of this leads to a huge industry, Germany being especially involved, using loads of virgin plastic.</p>
-<p>What can be done about it?
-We can design our products to last longer, we can also print recycling labels on them so they do not have to get burned after their first life. We can take care to only print functional objects, not just fun toys nobody uses.
-Yet, none of that prevents the use of virgin plastics. If you buy a spool of filament, there are some recycled options, but usually at twice the price at worse quality. No wonder recycled filament fails to convince the masses. It is mostly a fun thing YouTubers can pursue, not a valid commercial process.</p>

-<p>In my opinion, the core problem is the nonexistent economic feasibility of a proper recycling process. Identifying the exact material of a piece of trash is a very hard problem, definitely not solved yet. So why do we mix the plastic up in the first place?

-<p>I want to get people to wash and separate their trash for me, which are the most expensive steps in the recycling process. There is a willingness to take the extra step, and even if just my mom collects bottle caps for me, that is more than I can realistically use up.
-This only really works when I am thinking in a local and decentral environment.
-The existing recycling facilities clearly will not be able to provide 200 different containers for 200 different types of plastic.
-Starting the process with clean and sorted materials, like bottle caps (HDPE) or failed prints (PET-G), I start off with an advantage.

-<p>This is the Filastruder, designed and made by Tim Elmore, in an attempt to create the cheapest viable way to extrude plastic. The biggest cost issue is the tight industrial tolerances in thickness that have to be adhered to. This is in essence what separates good from the bad filament. The industry standard nowadays is at +-0.03mm. Hard to achieve on a DIY setup, but not unheard of. The setup, like any bigger industry equivalent, consists of a motor pressing plastic pellets through a heated screw, extruding molten plastic at the end through a nozzle, and setting the diameter. The leftmost machine is responsible for winding the filament properly onto a spool.</p>

- <p>Being involved with 3D Printers, there is the issue of sustainability that I am confronted with regularly.
-Most 3D printed parts never get recycled and add to the global waste problem, rather than reducing it.
-The printer most certainly doesn’t care what it is printing, the main problem is the dimensional accuracy and the purity of the material. All of this leads to a huge industry, Germany being especially involved, using loads of virgin plastic.</p>
-<p>What can be done about it?
-We can design our products to last longer, we can also print recycling labels on them so they do not have to get burned after their first life. We can take care to only print functional objects, not just fun toys nobody uses.
-Yet, none of that prevents the use of virgin plastics. If you buy a spool of filament, there are some recycled options, but usually at twice the price at worse quality. No wonder recycled filament fails to convince the masses. It is mostly a fun thing YouTubers can pursue, not a valid commercial process.</p>
+ <p>Als 3D-Druck-Enthusiast sehe ich mich regelmäßig mit dem Thema Nachhaltigkeit konfrontiert.<br />
+Die meisten 3D-gedruckten Teile werden nie recycelt und tragen eher zum globalen Müllproblem bei, als es zu reduzieren.<br />
+Das Problem liegt weniger beim Drucker selbst als bei der <strong>dimensionalen Genauigkeit</strong> und der <strong>Reinheit des Materials</strong>. Dies führt zu einer riesigen Industrie, insbesondere in Deutschland, die enorme Mengen an <strong>Neukunststoff</strong> verbraucht.</p>
+<h3 id="Was_kann_man_tun?">Was kann man tun?</h3>
+<p>Wir können Produkte langlebiger gestalten, Recycling-Labels aufdrucken und nur funktionale Objekte drucken. Dennoch verhindert dies nicht die Nutzung von Neukunststoffen. Recycelter Filament ist oft doppelt so teuer bei schlechterer Qualität – kein Wunder, dass er kaum Verbreitung findet.</p>

-<p>In my opinion, the core problem is the nonexistent economic feasibility of a proper recycling process. Identifying the exact material of a piece of trash is a very hard problem, definitely not solved yet. So why do we mix the plastic up in the first place? There is a general willingness of people to recycle, but the system for it is missing.</p>
-<h1 id="The_Master_Plan">The Master Plan</h1>
-<p>I want to get people to wash and separate their trash for me, which are the most expensive steps in the recycling process. There is a willingness to take the extra step, and even if just my mom collects bottle caps for me, that is more than I can realistically use up.
-This only really works when I am thinking in a local and decentral environment.
-The existing recycling facilities clearly will not be able to provide 200 different containers for 200 different types of plastic.
-Starting the process with clean and sorted materials, like bottle caps (HDPE) or failed prints (PET-G), I start off with an advantage.
-Now I have to take apart the trash into evenly sized particles.

-<p>With these awesome open-source drawings, I was able to cobble together my very own very dangerous plastic shredder.</p>
-<p>After finding some way to drive this massive axis, I feed the beast and hopefully get tiny pretty uniform plastic bits that are ready to begin the cycle of life anew.</p>
-<p>The solution for the motorization was an old and used garden shredder that still had an intact motor and wiring.
-We cut it in half and attached it to the shredder box.</p>
+<p>Das Kernproblem ist die <strong>fehlende wirtschaftliche Machbarkeit</strong> eines echten Recyclings. Das exakte Identifizieren von Kunststoffarten ist extrem schwierig und noch ungelöst. Es gibt Bereitschaft zu recyceln, aber das System fehlt.</p>

+<p>Ich möchte Menschen motivieren, ihren Müll <strong>zu waschen und zu sortieren</strong>, die teuersten Schritte im Recyclingprozess. Selbst kleine Beiträge, wie meine Mutter, die Flaschendeckel sammelt, sind wertvoll.<br />
+Dies funktioniert nur in einem <strong>lokalen, dezentralen Umfeld</strong>. Existierende Recyclinganlagen können nicht 200 verschiedene Kunststoffarten trennen.</p>
+<p>Mit sauberem, sortiertem Material – etwa Flaschendeckel (HDPE) oder fehlerhafte Drucke (PET-G) – starte ich bereits im Vorteil. Jetzt müssen die Teile noch in <strong>gleichmäßige Partikel</strong> zerkleinert werden.</p>

-<p>After replacing the weak force transmission screw for an industrial coupler, we were ready to try it out. Obviously, there are still security concerns in this prototype, a proper hopper is already being made.</p>
-<p>Nevertheless, we are confident that this shredder will be able to deal with the light sorts of plastic we are thinking of.

-<p>This is the Filastruder, designed and made by Tim Elmore, in an attempt to create the cheapest viable way to extrude plastic. The biggest cost issue is the tight industrial tolerances in thickness that have to be adhered to. This is in essence what separates good from the bad filament. The industry standard nowadays is at +-0.03mm. Hard to achieve on a DIY setup, but not unheard of. The setup, like any bigger industry equivalent, consists of a motor pressing plastic pellets through a heated screw, extruding molten plastic at the end through a nozzle, and setting the diameter. The leftmost machine is responsible for winding the filament properly onto a spool.</p>
-<p>Here you can see the extrusion process in action.</p>

-<p>I love hosting, I love experimenting in the Kitchen. Starting with homebrews was a natural fit for me and during the first wave of Covid-19, I went the whole homebrewer’s route of bottle fermentation and small batches later elevating my game with larger batches of 50 liters and a pressure tank system.</p>
-<p>Starting out, I found it fascinating, how just 4 rather simple ingredients, malt, hops, water and yeast, can form such an incredible range of taste experiences. It was and still is, a tremendous learning experience, where one slowly has to accept not being able to control the process fully and find room for creativity.</p>
-<p>Why do I present such an unrelated non-academic hobby here? I simply do not regard it as unrelated, experimenting and optimizing a process and a workflow, creating optimal conditions for the yeast to do its job feels very similar to approaching a coding project.
-Yeast and what it does fascinates me. Every time I open the latch to release some pressure on the Tank I think of the awesome symbiotic relationships yeast has with humans and how many different strains live there together to create a unique, yet tailored flavor. Several ideas are floating around of changing the brewing process by capturing the created carbon dioxide and using it productively. I could see a car tire being filled with my beer gas, or an algae farm munching away on my CO2 byproducts. Within a closed-loop pressurized system, such ideas actually become realizable and I would love to explore them further.</p>
-<p>I am not yet an expert on algae, but I can manage with yeast and I believe they can coexist and create a more sustainable cycle of production.
-Young Henrys, a brewery in Australia is already incorporating algae into its industrial process:
-<a href="https://younghenrys.com/algae">The Algae project</a></p>
-<p>Such ideas do not come into the industry by themselves: I believe that art and the exploratory discovery of novel techniques are the same things. Good and inventive design can improve society and make steps towards sustainability. I want to be part of that and would love to find new ways of using yeast in other design contexts: See whether I can make them work in a closed circular system, make them calculate things for me, or simply making my next beer taste awesome with just the right amount of fizz.</p>

+<h3 id="Mein_eigenes_Bier_herstellen">Mein eigenes Bier herstellen</h3>
+<p>Ich liebe es zu veranstalten, ich liebe es, in der Küche zu experimentieren. Mit Homebrews zu starten, war für mich eine natürliche Entscheidung, und während der ersten Covid-19-Welle habe ich den kompletten Heimbräuerweg mit Flaschenfermentation und kleinen Chargen eingeschlagen, später habe ich mein Setup auf 50-Liter-Chargen mit Drucktank-System erweitert.</p>
+<p>Zu Beginn war ich fasziniert, wie aus nur <strong>vier einfachen Zutaten</strong> – Malz, Hopfen, Wasser und Hefe – ein so unglaubliches Spektrum an Geschmackserlebnissen entstehen kann. Es war und ist immer noch ein <strong>tremendales Lernprojekt</strong>, bei dem man langsam akzeptieren muss, dass man den Prozess nicht vollständig kontrollieren kann, und gleichzeitig Raum für Kreativität findet.</p>
+<p>Warum präsentiere ich dieses scheinbar nicht-akademische Hobby hier? Ich sehe es nicht als irrelevant an: <strong>Experimentieren und Optimieren eines Prozesses und Workflows</strong>, optimale Bedingungen für die Hefe zu schaffen, fühlt sich dem Ansatz eines Programmierprojekts sehr ähnlich an.</p>
+<p>Hefe und ihre Wirkung faszinieren mich. Jedes Mal, wenn ich den Verschluss öffne, um etwas Druck aus dem Tank abzulassen, denke ich an die erstaunlichen symbiotischen Beziehungen der Hefe mit Menschen und wie viele verschiedene Stämme zusammenleben, um einen einzigartigen, maßgeschneiderten Geschmack zu erzeugen.<br />
+Es gibt einige Ideen, den Brauprozess zu verändern, indem das erzeugte CO₂ aufgefangen und produktiv genutzt wird – z. B. ein Autoreifen gefüllt mit Biergas oder eine Algenfarm, die das CO₂ aufnimmt. Innerhalb eines <strong>geschlossenen, druckbeaufschlagten Systems</strong> werden solche Ideen tatsächlich realisierbar, und ich möchte sie weiter erforschen.</p>
+<p>Ich bin noch kein Experte für Algen, aber mit Hefe komme ich klar, und ich glaube, dass sie koexistieren und einen nachhaltigeren Produktionszyklus schaffen können.<br />
+Die australische Brauerei Young Henrys integriert Algen bereits in ihren industriellen Prozess: <a href="https://younghenrys.com/algae">The Algae project</a></p>
+<p>Solche Ideen kommen nicht von selbst in die Industrie: Ich glaube, dass Kunst und die experimentelle Entdeckung neuer Techniken dasselbe sind. <strong>Gutes, erfinderisches Design</strong> kann die Gesellschaft verbessern und Schritte in Richtung Nachhaltigkeit gehen.

-<p>As you can see, the design faces some questionable choices, but all mechanics are homemade from the ground up and I learned a lot. I often struggle to enjoy competitive games and think there is potential in a co-dependent game interface. During early testing, we often found that it enforces player communication since already the tutorial is quite hard to beat.
-Due to me being a leftie, perhaps not entirely smart, I gave player one the keyboard arrows to work with and player two the WASD keys and left and right mouse buttons for grappling and shooting. For the game, it has an interesting side effect, in that players are forced not only to interact through the differing information on each player's screen but also have to physically interact and coordinate the controls.</p>
-<p>As you can perhaps see, the ball-rolling navigation is quite hard to use.
-It is a purely physics-based system, where, depending on the materiality of the ball, its weight, and therefore its inertia will drastically change.</p>
-<p>On small screens, the prototype version of the game is virtually impossible to control and several visual bugs within the viewport still obfuscate items when they are too close. Considering that virtually all the mechanics are written from scratch, with a follow-me camera, collision detection, smart moving agents, and a still very wonky-looking grappling gun, I still think it deserves a spot in this portfolio.
-For this project I focused completely on the mechanics of the game, resulting in lots of used prefabs and readymade 3D Objects. Next time, I want to do that myself too.</p>
-<p>I enjoyed my stint into Unity a lot and am looking forward to creating my first VR application and would love to try out some form of mechanics where the user vision is completely obfuscated by VR and they have to carry their eyes as a handheld connected camera so that the players can move around the camera itself with their hands.</p>
+<p>Das Design enthält einige fragwürdige Entscheidungen, aber alle Mechaniken sind <strong>von Grund auf selbst entwickelt</strong>, und ich habe viel dabei gelernt. Ich spiele selten kompetitive Spiele, sehe aber Potenzial in einer <strong>kooperativen, voneinander abhängigen Spielmechanik</strong>. Schon das Tutorial erfordert intensive Spielerkommunikation.</p>
+<p>Als Linkshänder habe ich Spieler eins die Pfeiltasten gegeben und Spieler zwei die WASD-Tasten sowie die linken und rechten Maustasten für Schießen und Greifhaken. Das führt zu einem interessanten Nebeneffekt: Spieler müssen nicht nur über unterschiedliche Informationen auf ihren Bildschirmen kommunizieren, sondern auch ihre Steuerung physisch koordinieren.</p>
+<p>Die <strong>Ball-Navigation</strong> ist ziemlich schwer zu kontrollieren.<br />
+Es handelt sich um ein <strong>rein physikbasiertes System</strong>, bei dem Material, Gewicht und Trägheit der Kugel die Bewegung stark beeinflussen.</p>
+<p>Auf kleinen Bildschirmen ist die Steuerung praktisch unmöglich, und einige visuelle Bugs verdecken Objekte bei zu naher Ansicht. Dennoch, da fast alle Mechaniken von Grund auf programmiert wurden – inklusive Follow-Camera, Kollisionsabfrage, smarten Agenten und einem noch etwas wackeligen Greifhaken – verdient das Projekt einen Platz im Portfolio.</p>
+<p>Für dieses Projekt habe ich mich komplett auf <strong>Mechaniken</strong> konzentriert, weshalb viele fertige Prefabs und 3D-Objekte verwendet wurden. Beim nächsten Mal möchte ich diese auch selbst erstellen.</p>
+<p>Ich habe Unity sehr genossen und freue mich darauf, meine erste <strong>VR-Anwendung</strong> zu entwickeln.<br />
+Ich möchte Mechaniken ausprobieren, bei denen die Sicht des Spielers durch VR komplett blockiert wird und die Augen als <strong>tragbare, verbundene Kamera</strong> bewegt werden, sodass die Spieler die Kamera selbst physisch steuern können.</p>

- <p>Being involved with 3D Printers, there is the issue of sustainability that I am confronted with regularly.
-Most 3D printed parts never get recycled and add to the global waste problem, rather than reducing it.
-The printer most certainly doesn’t care what it is printing, the main problem is the dimensional accuracy and the purity of the material. All of this leads to a huge industry, Germany being especially involved, using loads of virgin plastic.</p>
-<p>What can be done about it?
-We can design our products to last longer, we can also print recycling labels on them so they do not have to get burned after their first life. We can take care to only print functional objects, not just fun toys nobody uses.
-Yet, none of that prevents the use of virgin plastics. If you buy a spool of filament, there are some recycled options, but usually at twice the price at worse quality. No wonder recycled filament fails to convince the masses. It is mostly a fun thing YouTubers can pursue, not a valid commercial process.</p>
+ <p>Als 3D-Druck-Enthusiast sehe ich mich regelmäßig mit dem Thema Nachhaltigkeit konfrontiert.<br />
+Die meisten 3D-gedruckten Teile werden nie recycelt und tragen eher zum globalen Müllproblem bei, als es zu reduzieren.<br />
+Das Problem liegt weniger beim Drucker selbst als bei der <strong>dimensionalen Genauigkeit</strong> und der <strong>Reinheit des Materials</strong>. Dies führt zu einer riesigen Industrie, insbesondere in Deutschland, die enorme Mengen an <strong>Neukunststoff</strong> verbraucht.</p>

-<p>In my opinion, the core problem is the nonexistent economic feasibility of a proper recycling process. Identifying the exact material of a piece of trash is a very hard problem, definitely not solved yet. So why do we mix the plastic up in the first place? There is a general willingness of people to recycle, but the system for it is missing.</p>
-<h1 id="The_Master_Plan">The Master Plan</h1>
-<p>I want to get people to wash and separate their trash for me, which are the most expensive steps in the recycling process. There is a willingness to take the extra step, and even if just my mom collects bottle caps for me, that is more than I can realistically use up.
-This only really works when I am thinking in a local and decentral environment.
-The existing recycling facilities clearly will not be able to provide 200 different containers for 200 different types of plastic.
-Starting the process with clean and sorted materials, like bottle caps (HDPE) or failed prints (PET-G), I start off with an advantage.
-Now I have to take apart the trash into evenly sized particles.

-<p>After finding some way to drive this massive axis, I feed the beast and hopefully get tiny pretty uniform plastic bits that are ready to begin the cycle of life anew.</p>

-<p>After replacing the weak force transmission screw for an industrial coupler, we were ready to try it out. Obviously, there are still security concerns in this prototype, a proper hopper is already being made.</p>
-<p>Nevertheless, we are confident that this shredder will be able to deal with the light sorts of plastic we are thinking of.
-As you can see, I am now able to produce awesome confetti but to do more with the plastic flakes I have to extrude them.</p>
-<h2 id="Meet_the_Filastruder">Meet the Filastruder</h2>
-<p>This is the Filastruder, designed and made by Tim Elmore, in an attempt to create the cheapest viable way to extrude plastic. The biggest cost issue is the tight industrial tolerances in thickness that have to be adhered to. This is in essence what separates good from the bad filament. The industry standard nowadays is at +-0.03mm. Hard to achieve on a DIY setup, but not unheard of. The setup, like any bigger industry equivalent, consists of a motor pressing plastic pellets through a heated screw, extruding molten plastic at the end through a nozzle, and setting the diameter. The leftmost machine is responsible for winding the filament properly onto a spool.</p>
-<p>Here you can see the extrusion process in action.</p>
+<p>Nach Austausch der schwachen Kraftübertragungsschraube gegen einen Industrie-Kuppler waren wir startklar. Sicherheit bleibt ein Thema, ein richtiger Trichter ist in Arbeit.</p>

+<p>Der <strong>Filastruder</strong>, entworfen von Tim Elmore, bietet eine kostengünstige Möglichkeit, Filament zu extrudieren.<br />
+Die größten Herausforderungen: <strong>präzise Durchmesserkontrolle</strong> ±0,03 mm, sonst schwankt die Qualität.</p>
+<p>Motor presst Kunststoffpellets durch eine beheizte Schraube, am Ende wird durch die Düse extrudiert und der Durchmesser eingestellt. Links wickelt die Maschine das Filament auf eine Spule.</p>

-<p>The Filastruder is controlled by an Arduino and is highly configurable. The laser sensor visible in the video is already working, but I am missing more direct control over the diameter of the filament.</p>
-<p>When it all really comes down to the single variable of the filament diameter responsible for the quality of my recycled project, a simple Machine Learning optimization directly jumps at me: I have a few variables like winder speed, extrusion speed, heat, and cooling intensity. These variables can be optimized on the fly for an exact diameter. This is actually roughly how virgin filament is produced, commercial facilities just manage much faster.</p>
-<p><img src="/assets/images/recycling_variables.png" alt="The variables in an iterative optimization" /></p>
-<p>So far, I am aware of a few companies and academic projects attempting this process, but none of them manage to get either the quality or the price of other products available. Automatization does not just take out jobs away, I think it can also be a helpful tool, for example tackling environmental issues such as this one.</p>
-<p>This project is very dear to my heart and I plan to investigate it further in the form of a master thesis.
-The realization will require many skills I am already picking up or still need to work on within the Design and Computation program.

- <p>Being involved with 3D Printers, there is the issue of sustainability that I am confronted with regularly.
-Most 3D printed parts never get recycled and add to the global waste problem, rather than reducing it.
-The printer most certainly doesn’t care what it is printing, the main problem is the dimensional accuracy and the purity of the material. All of this leads to a huge industry, Germany being especially involved, using loads of virgin plastic.</p>
-<p>What can be done about it?
-We can design our products to last longer, we can also print recycling labels on them so they do not have to get burned after their first life. We can take care to only print functional objects, not just fun toys nobody uses.
-Yet, none of that prevents the use of virgin plastics. If you buy a spool of filament, there are some recycled options, but usually at twice the price at worse quality. No wonder recycled filament fails to convince the masses. It is mostly a fun thing YouTubers can pursue, not a valid commercial process.</p>
+ <p>Als 3D-Druck-Enthusiast sehe ich mich regelmäßig mit dem Thema Nachhaltigkeit konfrontiert.<br />
+Die meisten 3D-gedruckten Teile werden nie recycelt und tragen eher zum globalen Müllproblem bei, als es zu reduzieren.<br />
+Das Problem liegt weniger beim Drucker selbst als bei der <strong>dimensionalen Genauigkeit</strong> und der <strong>Reinheit des Materials</strong>. Dies führt zu einer riesigen Industrie, insbesondere in Deutschland, die enorme Mengen an <strong>Neukunststoff</strong> verbraucht.</p>
+<h3 id="Was_kann_man_tun?">Was kann man tun?</h3>
+<p>Wir können Produkte langlebiger gestalten, Recycling-Labels aufdrucken und nur funktionale Objekte drucken. Dennoch verhindert dies nicht die Nutzung von Neukunststoffen. Recycelter Filament ist oft doppelt so teuer bei schlechterer Qualität – kein Wunder, dass er kaum Verbreitung findet.</p>

-<p>In my opinion, the core problem is the nonexistent economic feasibility of a proper recycling process. Identifying the exact material of a piece of trash is a very hard problem, definitely not solved yet. So why do we mix the plastic up in the first place? There is a general willingness of people to recycle, but the system for it is missing.</p>
-<h1 id="The_Master_Plan">The Master Plan</h1>
-<p>I want to get people to wash and separate their trash for me, which are the most expensive steps in the recycling process. There is a willingness to take the extra step, and even if just my mom collects bottle caps for me, that is more than I can realistically use up.
-This only really works when I am thinking in a local and decentral environment.
-The existing recycling facilities clearly will not be able to provide 200 different containers for 200 different types of plastic.
-Starting the process with clean and sorted materials, like bottle caps (HDPE) or failed prints (PET-G), I start off with an advantage.
-Now I have to take apart the trash into evenly sized particles.
-Meet:</p>
-<h2 id="The_Shredder">The Shredder</h2>
-<p>We built the Precious Plastic Shredder!</p>

-<p>With these awesome open-source drawings, I was able to cobble together my very own very dangerous plastic shredder.</p>
-<p>After finding some way to drive this massive axis, I feed the beast and hopefully get tiny pretty uniform plastic bits that are ready to begin the cycle of life anew.</p>
-<p>The solution for the motorization was an old and used garden shredder that still had an intact motor and wiring.
-We cut it in half and attached it to the shredder box.</p>
+<p>Das Kernproblem ist die <strong>fehlende wirtschaftliche Machbarkeit</strong> eines echten Recyclings. Das exakte Identifizieren von Kunststoffarten ist extrem schwierig und noch ungelöst. Es gibt Bereitschaft zu recyceln, aber das System fehlt.</p>
+<h1 id="Der_Masterplan">Der Masterplan</h1>
+<p>Ich möchte Menschen motivieren, ihren Müll <strong>zu waschen und zu sortieren</strong>, die teuersten Schritte im Recyclingprozess. Selbst kleine Beiträge, wie meine Mutter, die Flaschendeckel sammelt, sind wertvoll.<br />
+Dies funktioniert nur in einem <strong>lokalen, dezentralen Umfeld</strong>. Existierende Recyclinganlagen können nicht 200 verschiedene Kunststoffarten trennen.</p>
+<p>Mit sauberem, sortiertem Material – etwa Flaschendeckel (HDPE) oder fehlerhafte Drucke (PET-G) – starte ich bereits im Vorteil. Jetzt müssen die Teile noch in <strong>gleichmäßige Partikel</strong> zerkleinert werden.</p>

+<p>Mit diesen Open-Source-Zeichnungen konnte ich meinen eigenen, sehr gefährlichen Kunststoff-Shredder zusammenbauen.<br />
+Die Motorisierung übernahm ein alter Gartenschredder, der Motor und Verkabelung intakt hatte. Wir schnitten ihn auseinander und befestigten ihn am Shredder.</p>

-<p>After replacing the weak force transmission screw for an industrial coupler, we were ready to try it out. Obviously, there are still security concerns in this prototype, a proper hopper is already being made.</p>
-<p>Nevertheless, we are confident that this shredder will be able to deal with the light sorts of plastic we are thinking of.
-As you can see, I am now able to produce awesome confetti but to do more with the plastic flakes I have to extrude them.</p>
-<h2 id="Meet_the_Filastruder">Meet the Filastruder</h2>
-<p>This is the Filastruder, designed and made by Tim Elmore, in an attempt to create the cheapest viable way to extrude plastic. The biggest cost issue is the tight industrial tolerances in thickness that have to be adhered to. This is in essence what separates good from the bad filament. The industry standard nowadays is at +-0.03mm. Hard to achieve on a DIY setup, but not unheard of. The setup, like any bigger industry equivalent, consists of a motor pressing plastic pellets through a heated screw, extruding molten plastic at the end through a nozzle, and setting the diameter. The leftmost machine is responsible for winding the filament properly onto a spool.</p>
-<p>Here you can see the extrusion process in action.</p>
+<p>Nach Austausch der schwachen Kraftübertragungsschraube gegen einen Industrie-Kuppler waren wir startklar. Sicherheit bleibt ein Thema, ein richtiger Trichter ist in Arbeit.</p>
+<h2 id="Der_Filastruder">Der Filastruder</h2>
+<p>Der <strong>Filastruder</strong>, entworfen von Tim Elmore, bietet eine kostengünstige Möglichkeit, Filament zu extrudieren.<br />
+Die größten Herausforderungen: <strong>präzise Durchmesserkontrolle</strong> ±0,03 mm, sonst schwankt die Qualität.</p>
+<p>Motor presst Kunststoffpellets durch eine beheizte Schraube, am Ende wird durch die Düse extrudiert und der Durchmesser eingestellt. Links wickelt die Maschine das Filament auf eine Spule.</p>

-<p>The Filastruder is controlled by an Arduino and is highly configurable. The laser sensor visible in the video is already working, but I am missing more direct control over the diameter of the filament.</p>
-<p>When it all really comes down to the single variable of the filament diameter responsible for the quality of my recycled project, a simple Machine Learning optimization directly jumps at me: I have a few variables like winder speed, extrusion speed, heat, and cooling intensity. These variables can be optimized on the fly for an exact diameter. This is actually roughly how virgin filament is produced, commercial facilities just manage much faster.</p>
-<p><img src="/assets/images/recycling_variables.png" alt="The variables in an iterative optimization" /></p>
-<p>So far, I am aware of a few companies and academic projects attempting this process, but none of them manage to get either the quality or the price of other products available. Automatization does not just take out jobs away, I think it can also be a helpful tool, for example tackling environmental issues such as this one.</p>
-<p>This project is very dear to my heart and I plan to investigate it further in the form of a master thesis.
-The realization will require many skills I am already picking up or still need to work on within the Design and Computation program.

-<p>As you can see, the design faces some questionable choices, but all mechanics are homemade from the ground up and I learned a lot. I often struggle to enjoy competitive games and think there is potential in a co-dependent game interface. During early testing, we often found that it enforces player communication since already the tutorial is quite hard to beat.
-Due to me being a leftie, perhaps not entirely smart, I gave player one the keyboard arrows to work with and player two the WASD keys and left and right mouse buttons for grappling and shooting. For the game, it has an interesting side effect, in that players are forced not only to interact through the differing information on each player's screen but also have to physically interact and coordinate the controls.</p>
-<p>As you can perhaps see, the ball-rolling navigation is quite hard to use.
-It is a purely physics-based system, where, depending on the materiality of the ball, its weight, and therefore its inertia will drastically change.</p>
-<p>On small screens, the prototype version of the game is virtually impossible to control and several visual bugs within the viewport still obfuscate items when they are too close. Considering that virtually all the mechanics are written from scratch, with a follow-me camera, collision detection, smart moving agents, and a still very wonky-looking grappling gun, I still think it deserves a spot in this portfolio.
-For this project I focused completely on the mechanics of the game, resulting in lots of used prefabs and readymade 3D Objects. Next time, I want to do that myself too.</p>
-<p>I enjoyed my stint into Unity a lot and am looking forward to creating my first VR application and would love to try out some form of mechanics where the user vision is completely obfuscated by VR and they have to carry their eyes as a handheld connected camera so that the players can move around the camera itself with their hands.</p>
+<p>Das Design enthält einige fragwürdige Entscheidungen, aber alle Mechaniken sind <strong>von Grund auf selbst entwickelt</strong>, und ich habe viel dabei gelernt. Ich spiele selten kompetitive Spiele, sehe aber Potenzial in einer <strong>kooperativen, voneinander abhängigen Spielmechanik</strong>. Schon das Tutorial erfordert intensive Spielerkommunikation.</p>
+<p>Als Linkshänder habe ich Spieler eins die Pfeiltasten gegeben und Spieler zwei die WASD-Tasten sowie die linken und rechten Maustasten für Schießen und Greifhaken. Das führt zu einem interessanten Nebeneffekt: Spieler müssen nicht nur über unterschiedliche Informationen auf ihren Bildschirmen kommunizieren, sondern auch ihre Steuerung physisch koordinieren.</p>
+<p>Die <strong>Ball-Navigation</strong> ist ziemlich schwer zu kontrollieren.<br />
+Es handelt sich um ein <strong>rein physikbasiertes System</strong>, bei dem Material, Gewicht und Trägheit der Kugel die Bewegung stark beeinflussen.</p>
+<p>Auf kleinen Bildschirmen ist die Steuerung praktisch unmöglich, und einige visuelle Bugs verdecken Objekte bei zu naher Ansicht. Dennoch, da fast alle Mechaniken von Grund auf programmiert wurden – inklusive Follow-Camera, Kollisionsabfrage, smarten Agenten und einem noch etwas wackeligen Greifhaken – verdient das Projekt einen Platz im Portfolio.</p>
+<p>Für dieses Projekt habe ich mich komplett auf <strong>Mechaniken</strong> konzentriert, weshalb viele fertige Prefabs und 3D-Objekte verwendet wurden. Beim nächsten Mal möchte ich diese auch selbst erstellen.</p>
+<p>Ich habe Unity sehr genossen und freue mich darauf, meine erste <strong>VR-Anwendung</strong> zu entwickeln.<br />
+Ich möchte Mechaniken ausprobieren, bei denen die Sicht des Spielers durch VR komplett blockiert wird und die Augen als <strong>tragbare, verbundene Kamera</strong> bewegt werden, sodass die Spieler die Kamera selbst physisch steuern können.</p>

-<p>Access to Electricity is a basic human right. At first, that may seem over the top, but if one stops to think what all the little tasks that electricity can indirectly handle for us (lightning, laundry, cooking, freezing, heating, entertaining…) would consume in time and effort if we had to perform them manually, this idea becomes very clear. There are globally around 1 billion people without tier 2 access to electricity.</p>

-<p>People only know the intensity of labor that goes into everything when there is no electricity. And it is not even only about convenience, electricity is an enormous lifesaver in any number of scenarios, think just of hospitals or mobile phone networks that would be rendered completely useless without it. So we can easily agree on a need, a demand for electricity globally, for every person. But what about the supply? Why is there 1 billion undersupplied?
-The Answer: missing profitability. It would be a charity project to supply every last person on earth, not a profitable one. And while charitable projects are noble and should be pursued, the reality within capitalism shows that this is not the way it is going to happen.
-But what if we could come up with technology, or rather, a communal structure, that enables us to supply profitably, and still adapt to both, the difficult external factors (weather issues, remoteness, altitude, etc.) and the smaller purses of the undersupplied?</p>

+<p>Zugang zu Elektrizität ist ein grundlegendes Menschenrecht. Das mag zunächst übertrieben klingen, doch wenn man bedenkt, wie viele kleine Aufgaben der Strom uns indirekt abnimmt – Licht, Wäsche, Kochen, Kühlen, Heizen, Unterhaltung – wird schnell klar, wie viel Zeit und Aufwand ohne Elektrizität nötig wäre.

-<p>In an environment reliant on hydro-energy and solar (diesel transport is unreliable due to snowed-in mountain roads), over 6 months of snowy winter, frequent snowstorms, and temperatures of up to -35°C, securing the grid is hard.</p>
-<p>Our way to tackle the issue was to reject the in the western society very established notion of electricity as a homogenous product with centralized production and instead researched the possibilities of a predictive, self-correcting, and decentral grid.</p>
-<p>By prioritizing energy usage cases, instead of a full blackout during a storm, essential functions like radio towers and hospitals could be partially powered and maybe stay functioning. The binarity of either having electricity or not would be replaced by assigned quantities and timeslots, in a collective effort to be mindful and distribute the electricity necessity-based.
-The ultimate vision was a live predictive electricity market, where people could even earn money by selling their allotted, but not needed electricity.
-To gauge feasibility, I conducted several psychological acceptance studies and collected data on local electricity demands.
-I simulated a typical day of electricity demand in the Key monastery and the surrounding villages and mapped out the potential to install cost-efficient smart microgrid controllers enabling such an accurate and predictive behavior.
-The smart grid operator boxes available here in Germany cost several hundred, with installation several thousand Euros, not a feasible solution for the Indian population. Instead, we wanted to use Raspberry Pi's, which are interconnected through ethernet cables or local mesh networking.</p>

-<h2 id="Data_Collection">Data Collection</h2>
-<p>Building a questionnaire and visiting public schools during their English Classes, I had the chance to speak to a range of teenagers, answering questions about the state of electricity in their homes, generating more data than I could have accomplished running from door to door without any skills speaking local dialects. The questionnaire was as scientific as I could make it in such a situation and geared towards finding the type and number of electric devices in the homes and estimating typical usage scenarios.</p>
-<p>With a total of 145 participants from more than 6 different schools and roughly 4 different districts, all located in the Indian part of the Himalayas, the findings are as follows:</p>
-<p>The participants range from 11 to 53 years, with an average of 17 years.
-The average household has 6 members with an average of 5 smart devices. Only 2 percent of the Households had not a single smart device, but at the same time, only 42 percent had direct or indirect access to a laptop or computer. So the main body of smart devices consists of smartphones with a negligible portion of tablets.
-The average total amount of electrical devices is around 11 electrical appliances per house.</p>
-<p><strong>Subjective</strong> Quality Rating on a scale of 1 to 10:</p>
+<p>Das ist <strong>Tashi Gang</strong>, ein Dorf nahe des Klosters. Es beherbergt rund 50 Menschen und ist nur drei bis vier Monate im Sommer über eine Straße erreichbar. Den Rest des Jahres sind die Bewohner auf Hubschrauber-Erste-Hilfe angewiesen – erreichbar nur über einen funktionierenden Mobilfunkturm.</p>

+<h2 id="Das_Projekt">Das Projekt</h2>
+<p>In einer Umgebung, die auf Wasser- und Sonnenenergie angewiesen ist, mit über sechs Monaten Schnee, häufigen Schneestürmen und Temperaturen bis zu –35 °C, ist die Netzsicherung schwierig.</p>
+<p>Unser Ansatz war es, die im Westen etablierte Vorstellung von Elektrizität als homogenes, zentral erzeugtes Produkt zu hinterfragen und stattdessen die Möglichkeiten eines <strong>prädiktiven, sich selbst korrigierenden und dezentralen Netzes</strong> zu erforschen.</p>
+<p>Anstatt bei einem Sturm einen kompletten Blackout zu riskieren, könnten bei einer Priorisierung der Energieverwendung wichtige Funktionen – etwa Radiotürme oder Krankenhäuser – teilweise weiterbetrieben werden. Die Binarität von Strom / kein Strom würde durch ein System von <strong>Zuteilungen nach Bedarf und Zeitfenstern</strong> ersetzt.<br />
+Langfristig war die Vision ein <strong>lokaler, prädiktiver Strommarkt</strong>, bei dem Menschen überschüssige Energie verkaufen können.</p>
+<p>Zur Machbarkeitsprüfung führte ich psychologische Akzeptanzstudien durch und sammelte Daten zum lokalen Stromverbrauch. Anschließend simulierte ich einen typischen Strombedarfstag im Key-Kloster und in den umliegenden Dörfern und entwickelte Konzepte für kostengünstige <strong>Smart-Microgrid-Controller</strong>.</p>
+<p>Die hier in Deutschland verfügbaren Netzsteuerboxen kosten mehrere Hundert bis Tausend Euro – keine realistische Lösung für die Bevölkerung vor Ort. Stattdessen planten wir <strong>Raspberry Pi-basierte Systeme</strong>, vernetzt über Ethernet oder lokale Mesh-Netze.</p>
+<h2 id="Forschung">Forschung</h2>
+<p><img src="/images/Key_Monastery_Spiti.png" alt="Das Stromnetz des Key-Klosters" /></p>
+<h2 id="Datenerhebung">Datenerhebung</h2>
+<p>Durch den Besuch öffentlicher Schulen im Englischunterricht konnte ich mit Jugendlichen über den Stromzustand in ihren Haushalten sprechen und umfangreiche Daten erheben. Insgesamt nahmen <strong>145 Teilnehmer aus über sechs Schulen</strong> in etwa <strong>vier Distrikten</strong> teil – alle im indischen Himalaya.</p>
+<p>Der Altersdurchschnitt lag bei 17 Jahren. Durchschnittlich leben 6 Personen pro Haushalt mit etwa 5 Smart-Geräten. Nur 2 % der Haushalte hatten gar keine, 42 % verfügten über Computer oder Laptops.</p>
<blockquote>
-<p>Average quality in summer: 7.1
-Average quality in monsoon: 5.6
-Average quality in autumn: 7.1
-Average quality in winter: 4.0</p>
+<p>Durchschnittliche Stromqualität (1 – 10):<br />
+Sommer: 7,1 Monsun: 5,6 Herbst: 7,1 Winter: 4,0</p>
</blockquote>
-<p>So, as you would expect, during winter, but also when it rains, the felt quality drops by more than 30 percent on average.
-As for the daily supply time, the average sits at 15.1 hours out of 24, meaning the people have electricity only for 62.9 percent of the time, some, as for example the people in Diskit only have a sad 4 hours of daily access. On top of that, this estimation does not account for the snowfalls in Spiti for example, where it is not uncommon to experience 3 consecutive days of powercut or more.
-As the Power Meter is supplied by the government, a solid 82 percent of the houses have a working power meter, if one assumes that the 13 percent who did not know whether they have a power meter, do have one, we can say that around 95% of the houses have a power meter.</p>
-<p>Another goal of the studies was to find out what would incline people to be caring and sharing with the available electricity, something rather unimaginable here in Germany.</p>
-<p>In general, the uninformed openness to delaying usage of electricity on a scale of 1-10 was around 5.5, with the additional information that a smart delay would cause an overall price reduction, the acceptance went up to 6.9, a good 14%. This implies that people would be a lot more inclined to give up conveniences if the benefits have a direct impact on them.</p>
+<p>Im Winter oder bei Regen sinkt die Qualität also deutlich – um über 30 %.<br />
+Im Durchschnitt haben Haushalte <strong>15,1 Stunden Strom pro Tag</strong> (≈ 63 %). Einige Regionen, wie Diskit, nur rund 4 Stunden.</p>
+<p>Etwa 95 % der Haushalte besitzen funktionierende Stromzähler.</p>
+<p>Ein weiteres Ziel war herauszufinden, <strong>was Menschen dazu bewegt, Strom zu teilen oder zu verschieben</strong>.<br />
+Ohne zusätzliche Information lag die Bereitschaft zur Verzögerung des Verbrauchs bei 5,5 / 10 – mit Aussicht auf Kostenvorteile stieg sie auf 6,9.</p>
<h2 id="Simulation">Simulation</h2>
-<p>After collecting all the estimated electric appliances of the local population, I simulated the use of 200 Solar Panels with 300Wp each, once for simultaneous electricity use, and once for mitigated electricity peaks through smart optimization and electricity usage delay.
-<img src="/images/sam_sim.png" alt="SAM Simulation of a local solar system " />
-<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimized" /></p>
-<p>Although solar is definitely not the optimal choice here and generates lots of issues with energy storage and battery charging at negative degrees, we figured that this was the way to go for the project.
-And as you can see, optimizing peak usage can improve solar from generating only one-fifth of the demand in winter to about half the demand in winter. Keeping in mind here, that the added solar farm was only intended to supply additional energy and not replace existing solutions, such a "small" farm would be a real lifesaver there and optimize the limited space in extremely mountainous terrain.</p>
-<h2 id="Closing_words">Closing words</h2>
-<p>There are to sides which the problems can be tackled: we can bring the total energy production up, by adding more panels or electricity by other means, but we can also try and bring the total demand down. This is to be achieved by investing strictly in the most energy-efficient appliances. Even replacing older, not-so-efficient appliances might sometimes be of use.
-But ensuring efficient use is not the only way to bring down the overall demand.</p>
-<p>As introduced as core ideas for the whole project, sharing and delaying will prove immensely useful. How so?
-By sharing, we mean a concept that is already widely applied in the relevant areas. What to do in a Village that has no access to water? Will we send each household out to the faraway river to catch water for their family? Or would we join hands in a community effort to dig a central well used by everyone?</p>
-<p>So, when we look at sharing electricity, how would we apply the concept? We take the appliances that consume the most energy individually and scale them up in order to increase efficiency. For example, in our case, that is most applicable to electric heating. If we manage to heat central community spaces available for everyone, naturally, fewer individual rooms will have to be heated. Similarly, one could declare a room as a public cinema, where people come together and watch Tv on a big Projector. Twice as fun, and conserving a great deal of energy again. Such ideas and others have to be realized in order to be able to match the total demand with the available supply.</p>
-<p>Sadly, the project was never taken up further, and the situation for the people in the Spiti Valley has not improved. Two years ago, a road directly through the mountains was finished, making the population hopeful for an increase in tourism, increasing the chances of the economic viability of improved solutions.
-I spent my time there in the function of a research intern, having no real say in the realization of the project. The problem remains, and I still think that decentral solutions look to be the most promising for this specific location. Of course, the Himalayas present a bit of an extreme location, but that doesn't change the fact that people live there and have a basic human right to electricity.</p>
+<p>Basierend auf den Daten simulierte ich den Einsatz von <strong>200 Solarmodulen à 300 Wp</strong>, einmal mit und einmal ohne intelligente Laststeuerung.</p>
+<p><img src="/images/sam_sim.png" alt="SAM Simulation eines lokalen Solarsystems" /><br />
+<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimiert" /></p>
+<p>Auch wenn Solar nicht optimal ist – vor allem wegen Kälte und Batterielagerung – zeigte sich, dass <strong>intelligente Lastverteilung</strong> den nutzbaren Ertrag im Winter von einem Fünftel auf etwa die Hälfte steigern kann.</p>
+<h2 id="Schlusswort">Schlusswort</h2>
+<p>Das Problem lässt sich aus zwei Richtungen angehen:</p>
+<ol>
+<li><strong>Produktion erhöhen</strong> – mehr Module, mehr Energiequellen.</li>
+<li><strong>Verbrauch senken</strong> – effizientere Geräte, gemeinschaftliche Nutzung.</li>
+</ol>
+<p>Das Konzept des <strong>Teilens und Verzögerns</strong> ist zentral. Wie bei einem gemeinschaftlich genutzten Brunnen kann auch Strom gemeinschaftlich erzeugt und genutzt werden.<br />
+Gemeinsam beheizte Räume oder öffentliche Projekträume sparen Energie und fördern Gemeinschaft.</p>
+<p>Leider wurde das Projekt nie weitergeführt, und die Situation im Spiti-Tal hat sich kaum verbessert. Eine neue Bergstraße gibt Hoffnung auf mehr Tourismus – und damit auf wirtschaftlich tragfähige Lösungen.</p>
+<p>Ich selbst war als Forschungspraktikant beteiligt, ohne Einfluss auf die Umsetzung. Dennoch bin ich überzeugt, dass <strong>dezentrale Lösungen</strong> der richtige Weg sind – gerade für extreme Regionen wie den Himalaya.<br />
+Denn eines bleibt wahr: <strong>Elektrizität ist ein Menschenrecht.</strong></p>

-<p>Access to Electricity is a basic human right. At first, that may seem over the top, but if one stops to think what all the little tasks that electricity can indirectly handle for us (lightning, laundry, cooking, freezing, heating, entertaining…) would consume in time and effort if we had to perform them manually, this idea becomes very clear. There are globally around 1 billion people without tier 2 access to electricity.</p>

-<p>People only know the intensity of labor that goes into everything when there is no electricity. And it is not even only about convenience, electricity is an enormous lifesaver in any number of scenarios, think just of hospitals or mobile phone networks that would be rendered completely useless without it. So we can easily agree on a need, a demand for electricity globally, for every person. But what about the supply? Why is there 1 billion undersupplied?
-The Answer: missing profitability. It would be a charity project to supply every last person on earth, not a profitable one. And while charitable projects are noble and should be pursued, the reality within capitalism shows that this is not the way it is going to happen.
-But what if we could come up with technology, or rather, a communal structure, that enables us to supply profitably, and still adapt to both, the difficult external factors (weather issues, remoteness, altitude, etc.) and the smaller purses of the undersupplied?</p>

+<p>Zugang zu Elektrizität ist ein grundlegendes Menschenrecht.

-<p>In an environment reliant on hydro-energy and solar (diesel transport is unreliable due to snowed-in mountain roads), over 6 months of snowy winter, frequent snowstorms, and temperatures of up to -35°C, securing the grid is hard.</p>
-<p>Our way to tackle the issue was to reject the in the western society very established notion of electricity as a homogenous product with centralized production and instead researched the possibilities of a predictive, self-correcting, and decentral grid.</p>
-<p>By prioritizing energy usage cases, instead of a full blackout during a storm, essential functions like radio towers and hospitals could be partially powered and maybe stay functioning. The binarity of either having electricity or not would be replaced by assigned quantities and timeslots, in a collective effort to be mindful and distribute the electricity necessity-based.
-The ultimate vision was a live predictive electricity market, where people could even earn money by selling their allotted, but not needed electricity.
-To gauge feasibility, I conducted several psychological acceptance studies and collected data on local electricity demands.
-I simulated a typical day of electricity demand in the Key monastery and the surrounding villages and mapped out the potential to install cost-efficient smart microgrid controllers enabling such an accurate and predictive behavior.
-The smart grid operator boxes available here in Germany cost several hundred, with installation several thousand Euros, not a feasible solution for the Indian population. Instead, we wanted to use Raspberry Pi's, which are interconnected through ethernet cables or local mesh networking.</p>

-<h2 id="Data_Collection">Data Collection</h2>
-<p>Building a questionnaire and visiting public schools during their English Classes, I had the chance to speak to a range of teenagers, answering questions about the state of electricity in their homes, generating more data than I could have accomplished running from door to door without any skills speaking local dialects. The questionnaire was as scientific as I could make it in such a situation and geared towards finding the type and number of electric devices in the homes and estimating typical usage scenarios.</p>
-<p>With a total of 145 participants from more than 6 different schools and roughly 4 different districts, all located in the Indian part of the Himalayas, the findings are as follows:</p>
-<p>The participants range from 11 to 53 years, with an average of 17 years.
-The average household has 6 members with an average of 5 smart devices. Only 2 percent of the Households had not a single smart device, but at the same time, only 42 percent had direct or indirect access to a laptop or computer. So the main body of smart devices consists of smartphones with a negligible portion of tablets.
-The average total amount of electrical devices is around 11 electrical appliances per house.</p>
-<p><strong>Subjective</strong> Quality Rating on a scale of 1 to 10:</p>
+<p>Das ist <strong>Tashi Gang</strong>, ein Dorf nahe des Klosters. Es beherbergt rund 50 Menschen und ist nur drei bis vier Monate im Sommer über eine Straße erreichbar.

+<h2 id="Das_Projekt">Das Projekt</h2>
+<p>In einer Umgebung, die auf Wasser- und Sonnenenergie angewiesen ist, mit über sechs Monaten Schnee, häufigen Schneestürmen und Temperaturen bis zu –35 °C, ist die Netzsicherung schwierig.</p>
+<p>Unser Ansatz war es, die im Westen etablierte Vorstellung von Elektrizität als homogenes, zentral erzeugtes Produkt zu hinterfragen und stattdessen die Möglichkeiten eines <strong>prädiktiven, sich selbst korrigierenden und dezentralen Netzes</strong> zu erforschen.</p>
+<p>Anstatt bei einem Sturm einen kompletten Blackout zu riskieren, könnten bei einer Priorisierung der Energieverwendung wichtige Funktionen – etwa Radiotürme oder Krankenhäuser – teilweise weiterbetrieben werden. Die Binarität von Strom / kein Strom würde durch ein System von <strong>Zuteilungen nach Bedarf und Zeitfenstern</strong> ersetzt.<br />
+Langfristig war die Vision ein <strong>lokaler, prädiktiver Strommarkt</strong>, bei dem Menschen überschüssige Energie verkaufen können.</p>
+<p>Zur Machbarkeitsprüfung führte ich psychologische Akzeptanzstudien durch und sammelte Daten zum lokalen Stromverbrauch. Anschließend simulierte ich einen typischen Strombedarfstag im Key-Kloster und in den umliegenden Dörfern und entwickelte Konzepte für kostengünstige <strong>Smart-Microgrid-Controller</strong>.</p>
+<p>Die hier in Deutschland verfügbaren Netzsteuerboxen kosten mehrere Hundert bis Tausend Euro – keine realistische Lösung für die Bevölkerung vor Ort. Stattdessen planten wir <strong>Raspberry Pi-basierte Systeme</strong>, vernetzt über Ethernet oder lokale Mesh-Netze.</p>
+<h2 id="Forschung">Forschung</h2>
+<p><img src="/images/Key_Monastery_Spiti.png" alt="Das Stromnetz des Key-Klosters" /></p>
+<h2 id="Datenerhebung">Datenerhebung</h2>
+<p>Durch den Besuch öffentlicher Schulen im Englischunterricht konnte ich mit Jugendlichen über den Stromzustand in ihren Haushalten sprechen und umfangreiche Daten erheben. Insgesamt nahmen <strong>145 Teilnehmer aus über sechs Schulen</strong> in etwa <strong>vier Distrikten</strong> teil – alle im indischen Himalaya.</p>
+<p>Der Altersdurchschnitt lag bei 17 Jahren. Durchschnittlich leben 6 Personen pro Haushalt mit etwa 5 Smart-Geräten. Nur 2 % der Haushalte hatten gar keine, 42 % verfügten über Computer oder Laptops.</p>
<blockquote>
-<p>Average quality in summer: 7.1
-Average quality in monsoon: 5.6
-Average quality in autumn: 7.1
-Average quality in winter: 4.0</p>
+<p>Durchschnittliche Stromqualität (1 – 10):<br />
+Sommer: 7,1 Monsun: 5,6 Herbst: 7,1 Winter: 4,0</p>
</blockquote>
-<p>So, as you would expect, during winter, but also when it rains, the felt quality drops by more than 30 percent on average.
-As for the daily supply time, the average sits at 15.1 hours out of 24, meaning the people have electricity only for 62.9 percent of the time, some, as for example the people in Diskit only have a sad 4 hours of daily access. On top of that, this estimation does not account for the snowfalls in Spiti for example, where it is not uncommon to experience 3 consecutive days of powercut or more.
-As the Power Meter is supplied by the government, a solid 82 percent of the houses have a working power meter, if one assumes that the 13 percent who did not know whether they have a power meter, do have one, we can say that around 95% of the houses have a power meter.</p>
-<p>Another goal of the studies was to find out what would incline people to be caring and sharing with the available electricity, something rather unimaginable here in Germany.</p>
-<p>In general, the uninformed openness to delaying usage of electricity on a scale of 1-10 was around 5.5, with the additional information that a smart delay would cause an overall price reduction, the acceptance went up to 6.9, a good 14%. This implies that people would be a lot more inclined to give up conveniences if the benefits have a direct impact on them.</p>
+<p>Im Winter oder bei Regen sinkt die Qualität also deutlich – um über 30 %.<br />
+Im Durchschnitt haben Haushalte <strong>15,1 Stunden Strom pro Tag</strong> (≈ 63 %). Einige Regionen, wie Diskit, nur rund 4 Stunden.</p>
+<p>Etwa 95 % der Haushalte besitzen funktionierende Stromzähler.</p>
+<p>Ein weiteres Ziel war herauszufinden, <strong>was Menschen dazu bewegt, Strom zu teilen oder zu verschieben</strong>.<br />
+Ohne zusätzliche Information lag die Bereitschaft zur Verzögerung des Verbrauchs bei 5,5 / 10 – mit Aussicht auf Kostenvorteile stieg sie auf 6,9.</p>
<h2 id="Simulation">Simulation</h2>
-<p>After collecting all the estimated electric appliances of the local population, I simulated the use of 200 Solar Panels with 300Wp each, once for simultaneous electricity use, and once for mitigated electricity peaks through smart optimization and electricity usage delay.
-<img src="/images/sam_sim.png" alt="SAM Simulation of a local solar system " />
-<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimized" /></p>
-<p>Although solar is definitely not the optimal choice here and generates lots of issues with energy storage and battery charging at negative degrees, we figured that this was the way to go for the project.
-And as you can see, optimizing peak usage can improve solar from generating only one-fifth of the demand in winter to about half the demand in winter. Keeping in mind here, that the added solar farm was only intended to supply additional energy and not replace existing solutions, such a "small" farm would be a real lifesaver there and optimize the limited space in extremely mountainous terrain.</p>
-<h2 id="Closing_words">Closing words</h2>
-<p>There are to sides which the problems can be tackled: we can bring the total energy production up, by adding more panels or electricity by other means, but we can also try and bring the total demand down. This is to be achieved by investing strictly in the most energy-efficient appliances. Even replacing older, not-so-efficient appliances might sometimes be of use.
-But ensuring efficient use is not the only way to bring down the overall demand.</p>
-<p>As introduced as core ideas for the whole project, sharing and delaying will prove immensely useful. How so?
-By sharing, we mean a concept that is already widely applied in the relevant areas. What to do in a Village that has no access to water? Will we send each household out to the faraway river to catch water for their family? Or would we join hands in a community effort to dig a central well used by everyone?</p>
-<p>So, when we look at sharing electricity, how would we apply the concept? We take the appliances that consume the most energy individually and scale them up in order to increase efficiency. For example, in our case, that is most applicable to electric heating. If we manage to heat central community spaces available for everyone, naturally, fewer individual rooms will have to be heated. Similarly, one could declare a room as a public cinema, where people come together and watch Tv on a big Projector. Twice as fun, and conserving a great deal of energy again. Such ideas and others have to be realized in order to be able to match the total demand with the available supply.</p>
-<p>Sadly, the project was never taken up further, and the situation for the people in the Spiti Valley has not improved. Two years ago, a road directly through the mountains was finished, making the population hopeful for an increase in tourism, increasing the chances of the economic viability of improved solutions.
-I spent my time there in the function of a research intern, having no real say in the realization of the project. The problem remains, and I still think that decentral solutions look to be the most promising for this specific location. Of course, the Himalayas present a bit of an extreme location, but that doesn't change the fact that people live there and have a basic human right to electricity.</p>
+<p>Basierend auf den Daten simulierte ich den Einsatz von <strong>200 Solarmodulen à 300 Wp</strong>, einmal mit und einmal ohne intelligente Laststeuerung.</p>
+<p><img src="/images/sam_sim.png" alt="SAM Simulation eines lokalen Solarsystems" /><br />
+<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimiert" /></p>
+<p>Auch wenn Solar nicht optimal ist – vor allem wegen Kälte und Batterielagerung – zeigte sich, dass <strong>intelligente Lastverteilung</strong> den nutzbaren Ertrag im Winter von einem Fünftel auf etwa die Hälfte steigern kann.</p>
+<h2 id="Schlusswort">Schlusswort</h2>
+<p>Das Problem lässt sich aus zwei Richtungen angehen:</p>
+<ol>
+<li><strong>Produktion erhöhen</strong> – mehr Module, mehr Energiequellen.</li>
+<li><strong>Verbrauch senken</strong> – effizientere Geräte, gemeinschaftliche Nutzung.</li>
+</ol>
+<p>Das Konzept des <strong>Teilens und Verzögerns</strong> ist zentral. Wie bei einem gemeinschaftlich genutzten Brunnen kann auch Strom gemeinschaftlich erzeugt und genutzt werden.<br />
+Gemeinsam beheizte Räume oder öffentliche Projekträume sparen Energie und fördern Gemeinschaft.</p>
+<p>Leider wurde das Projekt nie weitergeführt, und die Situation im Spiti-Tal hat sich kaum verbessert. Eine neue Bergstraße gibt Hoffnung auf mehr Tourismus – und damit auf wirtschaftlich tragfähige Lösungen.</p>
+<p>Ich selbst war als Forschungspraktikant beteiligt, ohne Einfluss auf die Umsetzung. Dennoch bin ich überzeugt, dass <strong>dezentrale Lösungen</strong> der richtige Weg sind – gerade für extreme Regionen wie den Himalaya.<br />
+Denn eines bleibt wahr: <strong>Elektrizität ist ein Menschenrecht.</strong></p>

- <p>Being involved with 3D Printers, there is the issue of sustainability that I am confronted with regularly.
-Most 3D printed parts never get recycled and add to the global waste problem, rather than reducing it.
-The printer most certainly doesn’t care what it is printing, the main problem is the dimensional accuracy and the purity of the material. All of this leads to a huge industry, Germany being especially involved, using loads of virgin plastic.</p>

-We can design our products to last longer, we can also print recycling labels on them so they do not have to get burned after their first life. We can take care to only print functional objects, not just fun toys nobody uses.
-Yet, none of that prevents the use of virgin plastics. If you buy a spool of filament, there are some recycled options, but usually at twice the price at worse quality. No wonder recycled filament fails to convince the masses. It is mostly a fun thing YouTubers can pursue, not a valid commercial process.</p>

-This only really works when I am thinking in a local and decentral environment.
-The existing recycling facilities clearly will not be able to provide 200 different containers for 200 different types of plastic.
-Starting the process with clean and sorted materials, like bottle caps (HDPE) or failed prints (PET-G), I start off with an advantage.

The industry standard nowadays is at +-0.03mm. Hard to achieve on a DIY setup, but not unheard of. The setup, like any bigger industry equivalent, consists of a motor pressing plastic pellets through a heated screw, extruding molten plastic at the end through a nozzle, and setting the diameter.

-<p>The Filastruder is controlled by an Arduino and is highly configurable. The laser sensor visible in the video is already working, but I am missing more direct control over the diameter of the filament.</p>
-<p>When it all really comes down to the single variable of the filament diameter responsible for the quality of my recycled project, a simple Machine Learning optimization directly jumps at me: I have a few variables like winder speed, extrusion speed, heat, and cooling intensity. These variables can be optimized on the fly for an exact diameter. This is actually roughly how virgin filament is produced, commercial facilities just manage much faster.</p>
-<p><img src="/assets/images/recycling_variables.png" alt="The variables in an iterative optimization" /></p>
-<p>So far, I am aware of a few companies and academic projects attempting this process, but none of them manage to get either the quality or the price of other products available. Automatization does not just take out jobs away, I think it can also be a helpful tool, for example tackling environmental issues such as this one.</p>
-<p>This project is very dear to my heart and I plan to investigate it further in the form of a master thesis.
-The realization will require many skills I am already picking up or still need to work on within the Design and Computation program.

-<p>Access to Electricity is a basic human right. At first, that may seem over the top, but if one stops to think what all the little tasks that electricity can indirectly handle for us (lightning, laundry, cooking, freezing, heating, entertaining…) would consume in time and effort if we had to perform them manually, this idea becomes very clear. There are globally around 1 billion people without tier 2 access to electricity.</p>

-<p>People only know the intensity of labor that goes into everything when there is no electricity. And it is not even only about convenience, electricity is an enormous lifesaver in any number of scenarios, think just of hospitals or mobile phone networks that would be rendered completely useless without it. So we can easily agree on a need, a demand for electricity globally, for every person. But what about the supply? Why is there 1 billion undersupplied?
-The Answer: missing profitability. It would be a charity project to supply every last person on earth, not a profitable one. And while charitable projects are noble and should be pursued, the reality within capitalism shows that this is not the way it is going to happen.
-But what if we could come up with technology, or rather, a communal structure, that enables us to supply profitably, and still adapt to both, the difficult external factors (weather issues, remoteness, altitude, etc.) and the smaller purses of the undersupplied?</p>

+<p>Zugang zu Elektrizität ist ein grundlegendes Menschenrecht. Das mag zunächst übertrieben klingen, doch wenn man bedenkt, wie viele kleine Aufgaben der Strom uns indirekt abnimmt – Licht, Wäsche, Kochen, Kühlen, Heizen, Unterhaltung – wird schnell klar, wie viel Zeit und Aufwand ohne Elektrizität nötig wäre. Weltweit leben etwa <strong>eine Milliarde Menschen</strong> ohne Zugang zu Strom auf dem sogenannten Tier-2-Level.</p>

+<p>Menschen erkennen erst dann, wie viel Arbeit in alltäglichen Dingen steckt, wenn sie keinen Strom haben. Doch es geht dabei nicht nur um Bequemlichkeit – Elektrizität rettet Leben: Krankenhäuser, Telekommunikation, Kühlung von Medikamenten – all das hängt davon ab.<br />
+Warum also sind immer noch so viele Menschen unterversorgt?<br />
+<strong>Die Antwort: fehlende Rentabilität.</strong> Es wäre ein wohltätiges, aber kein profitables Projekt, jede Person auf der Welt zu versorgen. Doch was, wenn wir eine Struktur finden könnten, die <strong>wirtschaftlich tragfähig</strong> ist und sich gleichzeitig an schwierige Bedingungen (Wetter, Abgeschiedenheit, Höhenlage) sowie an kleinere Einkommen anpassen kann?</p>

-<h2 id="The_Project">The Project</h2>
-<p>In an environment reliant on hydro-energy and solar (diesel transport is unreliable due to snowed-in mountain roads), over 6 months of snowy winter, frequent snowstorms, and temperatures of up to -35°C, securing the grid is hard.</p>
-<p>Our way to tackle the issue was to reject the in the western society very established notion of electricity as a homogenous product with centralized production and instead researched the possibilities of a predictive, self-correcting, and decentral grid.</p>
-<p>By prioritizing energy usage cases, instead of a full blackout during a storm, essential functions like radio towers and hospitals could be partially powered and maybe stay functioning. The binarity of either having electricity or not would be replaced by assigned quantities and timeslots, in a collective effort to be mindful and distribute the electricity necessity-based.
-The ultimate vision was a live predictive electricity market, where people could even earn money by selling their allotted, but not needed electricity.
-To gauge feasibility, I conducted several psychological acceptance studies and collected data on local electricity demands.
-I simulated a typical day of electricity demand in the Key monastery and the surrounding villages and mapped out the potential to install cost-efficient smart microgrid controllers enabling such an accurate and predictive behavior.
-The smart grid operator boxes available here in Germany cost several hundred, with installation several thousand Euros, not a feasible solution for the Indian population. Instead, we wanted to use Raspberry Pi's, which are interconnected through ethernet cables or local mesh networking.</p>

-<p><img src="/images/Key_Monastery_Spiti.png" alt="The Electricity layout of the Key Monastery" /></p>
-<h2 id="Data_Collection">Data Collection</h2>
-<p>Building a questionnaire and visiting public schools during their English Classes, I had the chance to speak to a range of teenagers, answering questions about the state of electricity in their homes, generating more data than I could have accomplished running from door to door without any skills speaking local dialects. The questionnaire was as scientific as I could make it in such a situation and geared towards finding the type and number of electric devices in the homes and estimating typical usage scenarios.</p>
-<p>With a total of 145 participants from more than 6 different schools and roughly 4 different districts, all located in the Indian part of the Himalayas, the findings are as follows:</p>
-<p>The participants range from 11 to 53 years, with an average of 17 years.
-The average household has 6 members with an average of 5 smart devices. Only 2 percent of the Households had not a single smart device, but at the same time, only 42 percent had direct or indirect access to a laptop or computer. So the main body of smart devices consists of smartphones with a negligible portion of tablets.
-The average total amount of electrical devices is around 11 electrical appliances per house.</p>
-<p><strong>Subjective</strong> Quality Rating on a scale of 1 to 10:</p>
+<p>Das ist <strong>Tashi Gang</strong>, ein Dorf nahe des Klosters. Es beherbergt rund 50 Menschen und ist nur drei bis vier Monate im Sommer über eine Straße erreichbar. Den Rest des Jahres sind die Bewohner auf Hubschrauber-Erste-Hilfe angewiesen – erreichbar nur über einen funktionierenden Mobilfunkturm.</p>

+<h2 id="Das_Projekt">Das Projekt</h2>
+<p>In einer Umgebung, die auf Wasser- und Sonnenenergie angewiesen ist, mit über sechs Monaten Schnee, häufigen Schneestürmen und Temperaturen bis zu –35 °C, ist die Netzsicherung schwierig.</p>
+<p>Unser Ansatz war es, die im Westen etablierte Vorstellung von Elektrizität als homogenes, zentral erzeugtes Produkt zu hinterfragen und stattdessen die Möglichkeiten eines <strong>prädiktiven, sich selbst korrigierenden und dezentralen Netzes</strong> zu erforschen.</p>
+<p>Anstatt bei einem Sturm einen kompletten Blackout zu riskieren, könnten bei einer Priorisierung der Energieverwendung wichtige Funktionen – etwa Radiotürme oder Krankenhäuser – teilweise weiterbetrieben werden. Die Binarität von Strom / kein Strom würde durch ein System von <strong>Zuteilungen nach Bedarf und Zeitfenstern</strong> ersetzt.<br />
+Langfristig war die Vision ein <strong>lokaler, prädiktiver Strommarkt</strong>, bei dem Menschen überschüssige Energie verkaufen können.</p>
+<p>Zur Machbarkeitsprüfung führte ich psychologische Akzeptanzstudien durch und sammelte Daten zum lokalen Stromverbrauch. Anschließend simulierte ich einen typischen Strombedarfstag im Key-Kloster und in den umliegenden Dörfern und entwickelte Konzepte für kostengünstige <strong>Smart-Microgrid-Controller</strong>.</p>
+<p>Die hier in Deutschland verfügbaren Netzsteuerboxen kosten mehrere Hundert bis Tausend Euro – keine realistische Lösung für die Bevölkerung vor Ort. Stattdessen planten wir <strong>Raspberry Pi-basierte Systeme</strong>, vernetzt über Ethernet oder lokale Mesh-Netze.</p>
+<h2 id="Forschung">Forschung</h2>
+<p><img src="/images/Key_Monastery_Spiti.png" alt="Das Stromnetz des Key-Klosters" /></p>
+<h2 id="Datenerhebung">Datenerhebung</h2>
+<p>Durch den Besuch öffentlicher Schulen im Englischunterricht konnte ich mit Jugendlichen über den Stromzustand in ihren Haushalten sprechen und umfangreiche Daten erheben. Insgesamt nahmen <strong>145 Teilnehmer aus über sechs Schulen</strong> in etwa <strong>vier Distrikten</strong> teil – alle im indischen Himalaya.</p>
+<p>Der Altersdurchschnitt lag bei 17 Jahren. Durchschnittlich leben 6 Personen pro Haushalt mit etwa 5 Smart-Geräten. Nur 2 % der Haushalte hatten gar keine, 42 % verfügten über Computer oder Laptops.</p>
<blockquote>
-<p>Average quality in summer: 7.1
-Average quality in monsoon: 5.6
-Average quality in autumn: 7.1
-Average quality in winter: 4.0</p>
+<p>Durchschnittliche Stromqualität (1 – 10):<br />
+Sommer: 7,1 Monsun: 5,6 Herbst: 7,1 Winter: 4,0</p>
</blockquote>
-<p>So, as you would expect, during winter, but also when it rains, the felt quality drops by more than 30 percent on average.
-As for the daily supply time, the average sits at 15.1 hours out of 24, meaning the people have electricity only for 62.9 percent of the time, some, as for example the people in Diskit only have a sad 4 hours of daily access. On top of that, this estimation does not account for the snowfalls in Spiti for example, where it is not uncommon to experience 3 consecutive days of powercut or more.
-As the Power Meter is supplied by the government, a solid 82 percent of the houses have a working power meter, if one assumes that the 13 percent who did not know whether they have a power meter, do have one, we can say that around 95% of the houses have a power meter.</p>
-<p>Another goal of the studies was to find out what would incline people to be caring and sharing with the available electricity, something rather unimaginable here in Germany.</p>
-<p>In general, the uninformed openness to delaying usage of electricity on a scale of 1-10 was around 5.5, with the additional information that a smart delay would cause an overall price reduction, the acceptance went up to 6.9, a good 14%. This implies that people would be a lot more inclined to give up conveniences if the benefits have a direct impact on them.</p>
+<p>Im Winter oder bei Regen sinkt die Qualität also deutlich – um über 30 %.<br />
+Im Durchschnitt haben Haushalte <strong>15,1 Stunden Strom pro Tag</strong> (≈ 63 %). Einige Regionen, wie Diskit, nur rund 4 Stunden.</p>
+<p>Etwa 95 % der Haushalte besitzen funktionierende Stromzähler.</p>
+<p>Ein weiteres Ziel war herauszufinden, <strong>was Menschen dazu bewegt, Strom zu teilen oder zu verschieben</strong>.<br />
+Ohne zusätzliche Information lag die Bereitschaft zur Verzögerung des Verbrauchs bei 5,5 / 10 – mit Aussicht auf Kostenvorteile stieg sie auf 6,9.</p>
<h2 id="Simulation">Simulation</h2>
-<p>After collecting all the estimated electric appliances of the local population, I simulated the use of 200 Solar Panels with 300Wp each, once for simultaneous electricity use, and once for mitigated electricity peaks through smart optimization and electricity usage delay.
-<img src="/images/sam_sim.png" alt="SAM Simulation of a local solar system " />
-<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimized" /></p>
-<p>Although solar is definitely not the optimal choice here and generates lots of issues with energy storage and battery charging at negative degrees, we figured that this was the way to go for the project.
-And as you can see, optimizing peak usage can improve solar from generating only one-fifth of the demand in winter to about half the demand in winter. Keeping in mind here, that the added solar farm was only intended to supply additional energy and not replace existing solutions, such a "small" farm would be a real lifesaver there and optimize the limited space in extremely mountainous terrain.</p>
-<h2 id="Closing_words">Closing words</h2>
-<p>There are to sides which the problems can be tackled: we can bring the total energy production up, by adding more panels or electricity by other means, but we can also try and bring the total demand down. This is to be achieved by investing strictly in the most energy-efficient appliances. Even replacing older, not-so-efficient appliances might sometimes be of use.
-But ensuring efficient use is not the only way to bring down the overall demand.</p>
-<p>As introduced as core ideas for the whole project, sharing and delaying will prove immensely useful. How so?
-By sharing, we mean a concept that is already widely applied in the relevant areas. What to do in a Village that has no access to water? Will we send each household out to the faraway river to catch water for their family? Or would we join hands in a community effort to dig a central well used by everyone?</p>
-<p>So, when we look at sharing electricity, how would we apply the concept? We take the appliances that consume the most energy individually and scale them up in order to increase efficiency. For example, in our case, that is most applicable to electric heating. If we manage to heat central community spaces available for everyone, naturally, fewer individual rooms will have to be heated. Similarly, one could declare a room as a public cinema, where people come together and watch Tv on a big Projector. Twice as fun, and conserving a great deal of energy again. Such ideas and others have to be realized in order to be able to match the total demand with the available supply.</p>
-<p>Sadly, the project was never taken up further, and the situation for the people in the Spiti Valley has not improved. Two years ago, a road directly through the mountains was finished, making the population hopeful for an increase in tourism, increasing the chances of the economic viability of improved solutions.
-I spent my time there in the function of a research intern, having no real say in the realization of the project. The problem remains, and I still think that decentral solutions look to be the most promising for this specific location. Of course, the Himalayas present a bit of an extreme location, but that doesn't change the fact that people live there and have a basic human right to electricity.</p>
+<p>Basierend auf den Daten simulierte ich den Einsatz von <strong>200 Solarmodulen à 300 Wp</strong>, einmal mit und einmal ohne intelligente Laststeuerung.</p>
+<p><img src="/images/sam_sim.png" alt="SAM Simulation eines lokalen Solarsystems" /><br />
+<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimiert" /></p>
+<p>Auch wenn Solar nicht optimal ist – vor allem wegen Kälte und Batterielagerung – zeigte sich, dass <strong>intelligente Lastverteilung</strong> den nutzbaren Ertrag im Winter von einem Fünftel auf etwa die Hälfte steigern kann.</p>
+<h2 id="Schlusswort">Schlusswort</h2>
+<p>Das Problem lässt sich aus zwei Richtungen angehen:</p>
+<ol>
+<li><strong>Produktion erhöhen</strong> – mehr Module, mehr Energiequellen.</li>
+<li><strong>Verbrauch senken</strong> – effizientere Geräte, gemeinschaftliche Nutzung.</li>
+</ol>
+<p>Das Konzept des <strong>Teilens und Verzögerns</strong> ist zentral. Wie bei einem gemeinschaftlich genutzten Brunnen kann auch Strom gemeinschaftlich erzeugt und genutzt werden.<br />
+Gemeinsam beheizte Räume oder öffentliche Projekträume sparen Energie und fördern Gemeinschaft.</p>
+<p>Leider wurde das Projekt nie weitergeführt, und die Situation im Spiti-Tal hat sich kaum verbessert. Eine neue Bergstraße gibt Hoffnung auf mehr Tourismus – und damit auf wirtschaftlich tragfähige Lösungen.</p>
+<p>Ich selbst war als Forschungspraktikant beteiligt, ohne Einfluss auf die Umsetzung. Dennoch bin ich überzeugt, dass <strong>dezentrale Lösungen</strong> der richtige Weg sind – gerade für extreme Regionen wie den Himalaya.<br />
+Denn eines bleibt wahr: <strong>Elektrizität ist ein Menschenrecht.</strong></p>

- <h2 id="2020:_discovering_jekyll">2020: discovering jekyll</h2>
-<p>For applying to my master's program in 2020, a portfolio was required, and since it was more or less for a design program, I wanted to have a nice website.
-After trying for a month to get what I wanted out of WordPress, and angrily quitting multiple times, I discovered <a href="https://jekyllrb.com">Jekyll</a>.
-Back then, <a href="https://gohugo.io">Hugo</a> and <a href="https://www.11ty.dev">11ty</a> were the newer kids on the block, but I was heavily relying on the free hosting from <a href="https://pages.github.com">GitHub Pages</a>, where Jekyll was the easiest to integrate.</p>
-<p>Back then, looking for inspiration, I had an ethics professor I really liked, and he had a Jekyll site with the <a href="https://mmistakes.github.io/minimal-mistakes/">Minimal Mistakes</a> theme.
-<a href="https://rainermuehlhoff.de">Prof. Mühlhoff</a></p>
-<p>I went about using Minimal Mistakes, and it was a great experience.
-The resulting portfolio at least got me into the master's, and I fell in love with the general idea of being able to write sites in markdown, while a program would take care of the rest.</p>
-<p>For years, Jekyll was my go-to for building static websites.
-It was familiar, widely supported, and part of the broader Ruby ecosystem.
-But over time, my frustrations grew—slow builds, complicated plugin setups, and a dependency stack that never felt quite right.
-To be honest, many of the drawbacks were totally not Jekyll’s fault. It was just slow, otherwise fine. But especially using GitHub Pages imposed quite a few limitations on plugins and themes.
-Also, maybe I didn’t put in enough effort, but I could never really get theme modifications working. Just extending the theme to show multiple authors was a pain—although it was eventually working.</p>
-<p>On now finishing the master's, I wanted a visual overhaul, and while browsing for inspiration again, using Jekyll at all got questioned again.
-I knew I wanted a static site generator, because markdown is the shit.
-So after looking around further, <strong><a href="https://www.getzola.org/">Zola</a></strong> emerged—actually through a chatbot suggestion 😄</p>
-<p>Recently, I made the leap to Zola, a Rust-powered static site generator, and I don't see myself going back.</p>
-<hr />
-<h2 id="rust_feels_right">rust feels right</h2>
-<p>I’ve always admired <a href="https://www.rust-lang.org/">Rust</a> for its speed, safety, and modern tooling.
-Using a static site generator built with Rust just made sense. <strong>Zola is fast</strong>—blazing fast.
-Even during local development, rebuilds are near-instant, and that alone makes the writing process smoother and more enjoyable.</p>
-<p>Plus, using something written in Rust means fewer external dependencies, no bundler hell, and zero Ruby setup headaches.
-I can just download the binary, run it, and get going. It respects my time.</p>

-<p>Beyond performance, Zola is just really well designed.
-Its template syntax (thanks to <a href="https://tera.netlify.app">Tera</a>) is more powerful and readable than Liquid.
-The built-in shortcodes, pagination, and asset pipelines all feel cohesive and purposeful.
-There’s very little “configuration over convention” fatigue that Jekyll often gave me.</p>
-<p>And even though both systems are markdown-based, migrating wasn’t just a matter of copy-pasting files.
-I had to rethink frontmatter, adjust templates, and wrangle image paths and shortcodes.
-The structure and behavior are different enough that it felt like a real rebuild—not just a port.</p>

-<h2 id="duckquill_made_me_switch">duckquill made me switch</h2>
-<p>The real catalyst, though? <a href="https://github.com/daudix/duckquill"><strong>Duckquill</strong></a>, a stunning Zola theme built by <a href="https://github.com/daudix">Daudix</a>.
-It struck the perfect balance between minimalism and elegance—exactly the aesthetic I wanted but could never quite achieve with Jekyll.
-Duckquill didn’t just make Zola usable for me; it made it <em>irresistible</em>.</p>
-<p>What really sets <strong>Duckquill</strong> apart—beyond its clean typography and smart layout—is how well it supports a vision of digital autonomy.
-The theme comes with <strong>Mastodon-powered comments</strong>, allowing for lightweight, federated interaction without relying on big centralized platforms.
-This fits perfectly with my goal of reclaiming control through <strong>self-hosting</strong>.
-Whether it's running my own site, owning my content, or interacting through the fediverse, Duckquill reinforces those values rather than working against them.
-It’s a rare example of design and infrastructure aligning with personal principles.</p>

-<h2 id="final_thoughts">final thoughts</h2>
-<p>Switching from Jekyll to Zola wasn’t effortless, but it was absolutely worth it.
-I now have a faster, more reliable, and better-looking site that’s easier to maintain and feels like it fits my tooling philosophy.</p>
-<p>If you're feeling the weight of your current setup, maybe it's time to try Zola—and give Duckquill a spin while you're at it.</p>

- <p>Being involved with 3D Printers, there is the issue of sustainability that I am confronted with regularly.
-Most 3D printed parts never get recycled and add to the global waste problem, rather than reducing it.
-The printer most certainly doesn’t care what it is printing, the main problem is the dimensional accuracy and the purity of the material. All of this leads to a huge industry, Germany being especially involved, using loads of virgin plastic.</p>
-<p>What can be done about it?
-We can design our products to last longer, we can also print recycling labels on them so they do not have to get burned after their first life. We can take care to only print functional objects, not just fun toys nobody uses.
-Yet, none of that prevents the use of virgin plastics. If you buy a spool of filament, there are some recycled options, but usually at twice the price at worse quality. No wonder recycled filament fails to convince the masses. It is mostly a fun thing YouTubers can pursue, not a valid commercial process.</p>
+ <p>Als 3D-Druck-Enthusiast sehe ich mich regelmäßig mit dem Thema Nachhaltigkeit konfrontiert.<br />
+Die meisten 3D-gedruckten Teile werden nie recycelt und tragen eher zum globalen Müllproblem bei, als es zu reduzieren.<br />
+Das Problem liegt weniger beim Drucker selbst als bei der <strong>dimensionalen Genauigkeit</strong> und der <strong>Reinheit des Materials</strong>. Dies führt zu einer riesigen Industrie, insbesondere in Deutschland, die enorme Mengen an <strong>Neukunststoff</strong> verbraucht.</p>
+<h3 id="Was_kann_man_tun?">Was kann man tun?</h3>
+<p>Wir können Produkte langlebiger gestalten, Recycling-Labels aufdrucken und nur funktionale Objekte drucken. Dennoch verhindert dies nicht die Nutzung von Neukunststoffen. Recycelter Filament ist oft doppelt so teuer bei schlechterer Qualität – kein Wunder, dass er kaum Verbreitung findet.</p>

-<p>In my opinion, the core problem is the nonexistent economic feasibility of a proper recycling process. Identifying the exact material of a piece of trash is a very hard problem, definitely not solved yet. So why do we mix the plastic up in the first place? There is a general willingness of people to recycle, but the system for it is missing.</p>
-<h1 id="The_Master_Plan">The Master Plan</h1>
-<p>I want to get people to wash and separate their trash for me, which are the most expensive steps in the recycling process. There is a willingness to take the extra step, and even if just my mom collects bottle caps for me, that is more than I can realistically use up.
-This only really works when I am thinking in a local and decentral environment.
-The existing recycling facilities clearly will not be able to provide 200 different containers for 200 different types of plastic.
-Starting the process with clean and sorted materials, like bottle caps (HDPE) or failed prints (PET-G), I start off with an advantage.
-Now I have to take apart the trash into evenly sized particles.

-<p>With these awesome open-source drawings, I was able to cobble together my very own very dangerous plastic shredder.</p>
-<p>After finding some way to drive this massive axis, I feed the beast and hopefully get tiny pretty uniform plastic bits that are ready to begin the cycle of life anew.</p>
-<p>The solution for the motorization was an old and used garden shredder that still had an intact motor and wiring.
-We cut it in half and attached it to the shredder box.</p>

+<p>Mit sauberem, sortiertem Material – etwa Flaschendeckel (HDPE) oder fehlerhafte Drucke (PET-G) – starte ich bereits im Vorteil. Jetzt müssen die Teile noch in <strong>gleichmäßige Partikel</strong> zerkleinert werden.</p>

-<p>After replacing the weak force transmission screw for an industrial coupler, we were ready to try it out. Obviously, there are still security concerns in this prototype, a proper hopper is already being made.</p>
-<p>Nevertheless, we are confident that this shredder will be able to deal with the light sorts of plastic we are thinking of.
-As you can see, I am now able to produce awesome confetti but to do more with the plastic flakes I have to extrude them.</p>
-<h2 id="Meet_the_Filastruder">Meet the Filastruder</h2>
-<p>This is the Filastruder, designed and made by Tim Elmore, in an attempt to create the cheapest viable way to extrude plastic. The biggest cost issue is the tight industrial tolerances in thickness that have to be adhered to. This is in essence what separates good from the bad filament. The industry standard nowadays is at +-0.03mm. Hard to achieve on a DIY setup, but not unheard of. The setup, like any bigger industry equivalent, consists of a motor pressing plastic pellets through a heated screw, extruding molten plastic at the end through a nozzle, and setting the diameter. The leftmost machine is responsible for winding the filament properly onto a spool.</p>
-<p>Here you can see the extrusion process in action.</p>
+<p>Nach Austausch der schwachen Kraftübertragungsschraube gegen einen Industrie-Kuppler waren wir startklar. Sicherheit bleibt ein Thema, ein richtiger Trichter ist in Arbeit.</p>

+<p>Der <strong>Filastruder</strong>, entworfen von Tim Elmore, bietet eine kostengünstige Möglichkeit, Filament zu extrudieren.<br />
+Die größten Herausforderungen: <strong>präzise Durchmesserkontrolle</strong> ±0,03 mm, sonst schwankt die Qualität.</p>
+<p>Motor presst Kunststoffpellets durch eine beheizte Schraube, am Ende wird durch die Düse extrudiert und der Durchmesser eingestellt. Links wickelt die Maschine das Filament auf eine Spule.</p>

-<p>The Filastruder is controlled by an Arduino and is highly configurable. The laser sensor visible in the video is already working, but I am missing more direct control over the diameter of the filament.</p>
-<p>When it all really comes down to the single variable of the filament diameter responsible for the quality of my recycled project, a simple Machine Learning optimization directly jumps at me: I have a few variables like winder speed, extrusion speed, heat, and cooling intensity. These variables can be optimized on the fly for an exact diameter. This is actually roughly how virgin filament is produced, commercial facilities just manage much faster.</p>
-<p><img src="/assets/images/recycling_variables.png" alt="The variables in an iterative optimization" /></p>
-<p>So far, I am aware of a few companies and academic projects attempting this process, but none of them manage to get either the quality or the price of other products available. Automatization does not just take out jobs away, I think it can also be a helpful tool, for example tackling environmental issues such as this one.</p>
-<p>This project is very dear to my heart and I plan to investigate it further in the form of a master thesis.
-The realization will require many skills I am already picking up or still need to work on within the Design and Computation program.

-<p>Access to Electricity is a basic human right. At first, that may seem over the top, but if one stops to think what all the little tasks that electricity can indirectly handle for us (lightning, laundry, cooking, freezing, heating, entertaining…) would consume in time and effort if we had to perform them manually, this idea becomes very clear. There are globally around 1 billion people without tier 2 access to electricity.</p>

-<p>People only know the intensity of labor that goes into everything when there is no electricity. And it is not even only about convenience, electricity is an enormous lifesaver in any number of scenarios, think just of hospitals or mobile phone networks that would be rendered completely useless without it. So we can easily agree on a need, a demand for electricity globally, for every person. But what about the supply? Why is there 1 billion undersupplied?
-The Answer: missing profitability. It would be a charity project to supply every last person on earth, not a profitable one. And while charitable projects are noble and should be pursued, the reality within capitalism shows that this is not the way it is going to happen.
-But what if we could come up with technology, or rather, a communal structure, that enables us to supply profitably, and still adapt to both, the difficult external factors (weather issues, remoteness, altitude, etc.) and the smaller purses of the undersupplied?</p>

+<p>Zugang zu Elektrizität ist ein grundlegendes Menschenrecht. Das mag zunächst übertrieben klingen, doch wenn man bedenkt, wie viele kleine Aufgaben der Strom uns indirekt abnimmt – Licht, Wäsche, Kochen, Kühlen, Heizen, Unterhaltung – wird schnell klar, wie viel Zeit und Aufwand ohne Elektrizität nötig wäre.

+Warum also sind immer noch so viele Menschen unterversorgt?<br />
+<strong>Die Antwort: fehlende Rentabilität.</strong> Es wäre ein wohltätiges, aber kein profitables Projekt, jede Person auf der Welt zu versorgen.

-<h2 id="The_Project">The Project</h2>
-<p>In an environment reliant on hydro-energy and solar (diesel transport is unreliable due to snowed-in mountain roads), over 6 months of snowy winter, frequent snowstorms, and temperatures of up to -35°C, securing the grid is hard.</p>
-<p>Our way to tackle the issue was to reject the in the western society very established notion of electricity as a homogenous product with centralized production and instead researched the possibilities of a predictive, self-correcting, and decentral grid.</p>
-<p>By prioritizing energy usage cases, instead of a full blackout during a storm, essential functions like radio towers and hospitals could be partially powered and maybe stay functioning. The binarity of either having electricity or not would be replaced by assigned quantities and timeslots, in a collective effort to be mindful and distribute the electricity necessity-based.
-The ultimate vision was a live predictive electricity market, where people could even earn money by selling their allotted, but not needed electricity.
-To gauge feasibility, I conducted several psychological acceptance studies and collected data on local electricity demands.
-I simulated a typical day of electricity demand in the Key monastery and the surrounding villages and mapped out the potential to install cost-efficient smart microgrid controllers enabling such an accurate and predictive behavior.
-The smart grid operator boxes available here in Germany cost several hundred, with installation several thousand Euros, not a feasible solution for the Indian population. Instead, we wanted to use Raspberry Pi's, which are interconnected through ethernet cables or local mesh networking.</p>

-<h2 id="Data_Collection">Data Collection</h2>
-<p>Building a questionnaire and visiting public schools during their English Classes, I had the chance to speak to a range of teenagers, answering questions about the state of electricity in their homes, generating more data than I could have accomplished running from door to door without any skills speaking local dialects. The questionnaire was as scientific as I could make it in such a situation and geared towards finding the type and number of electric devices in the homes and estimating typical usage scenarios.</p>
-<p>With a total of 145 participants from more than 6 different schools and roughly 4 different districts, all located in the Indian part of the Himalayas, the findings are as follows:</p>
-<p>The participants range from 11 to 53 years, with an average of 17 years.
-The average household has 6 members with an average of 5 smart devices. Only 2 percent of the Households had not a single smart device, but at the same time, only 42 percent had direct or indirect access to a laptop or computer. So the main body of smart devices consists of smartphones with a negligible portion of tablets.
-The average total amount of electrical devices is around 11 electrical appliances per house.</p>
-<p><strong>Subjective</strong> Quality Rating on a scale of 1 to 10:</p>
+<p>Das ist <strong>Tashi Gang</strong>, ein Dorf nahe des Klosters. Es beherbergt rund 50 Menschen und ist nur drei bis vier Monate im Sommer über eine Straße erreichbar.

+<h2 id="Das_Projekt">Das Projekt</h2>
+<p>In einer Umgebung, die auf Wasser- und Sonnenenergie angewiesen ist, mit über sechs Monaten Schnee, häufigen Schneestürmen und Temperaturen bis zu –35 °C, ist die Netzsicherung schwierig.</p>
+<p>Unser Ansatz war es, die im Westen etablierte Vorstellung von Elektrizität als homogenes, zentral erzeugtes Produkt zu hinterfragen und stattdessen die Möglichkeiten eines <strong>prädiktiven, sich selbst korrigierenden und dezentralen Netzes</strong> zu erforschen.</p>
+<p>Anstatt bei einem Sturm einen kompletten Blackout zu riskieren, könnten bei einer Priorisierung der Energieverwendung wichtige Funktionen – etwa Radiotürme oder Krankenhäuser – teilweise weiterbetrieben werden. Die Binarität von Strom / kein Strom würde durch ein System von <strong>Zuteilungen nach Bedarf und Zeitfenstern</strong> ersetzt.<br />
+Langfristig war die Vision ein <strong>lokaler, prädiktiver Strommarkt</strong>, bei dem Menschen überschüssige Energie verkaufen können.</p>
+<p>Zur Machbarkeitsprüfung führte ich psychologische Akzeptanzstudien durch und sammelte Daten zum lokalen Stromverbrauch. Anschließend simulierte ich einen typischen Strombedarfstag im Key-Kloster und in den umliegenden Dörfern und entwickelte Konzepte für kostengünstige <strong>Smart-Microgrid-Controller</strong>.</p>
+<p>Die hier in Deutschland verfügbaren Netzsteuerboxen kosten mehrere Hundert bis Tausend Euro – keine realistische Lösung für die Bevölkerung vor Ort. Stattdessen planten wir <strong>Raspberry Pi-basierte Systeme</strong>, vernetzt über Ethernet oder lokale Mesh-Netze.</p>
+<h2 id="Forschung">Forschung</h2>
+<p><img src="/images/Key_Monastery_Spiti.png" alt="Das Stromnetz des Key-Klosters" /></p>
+<h2 id="Datenerhebung">Datenerhebung</h2>
+<p>Durch den Besuch öffentlicher Schulen im Englischunterricht konnte ich mit Jugendlichen über den Stromzustand in ihren Haushalten sprechen und umfangreiche Daten erheben. Insgesamt nahmen <strong>145 Teilnehmer aus über sechs Schulen</strong> in etwa <strong>vier Distrikten</strong> teil – alle im indischen Himalaya.</p>
+<p>Der Altersdurchschnitt lag bei 17 Jahren. Durchschnittlich leben 6 Personen pro Haushalt mit etwa 5 Smart-Geräten. Nur 2 % der Haushalte hatten gar keine, 42 % verfügten über Computer oder Laptops.</p>
<blockquote>
-<p>Average quality in summer: 7.1
-Average quality in monsoon: 5.6
-Average quality in autumn: 7.1
-Average quality in winter: 4.0</p>
+<p>Durchschnittliche Stromqualität (1 – 10):<br />
+Sommer: 7,1 Monsun: 5,6 Herbst: 7,1 Winter: 4,0</p>
</blockquote>
-<p>So, as you would expect, during winter, but also when it rains, the felt quality drops by more than 30 percent on average.
-As for the daily supply time, the average sits at 15.1 hours out of 24, meaning the people have electricity only for 62.9 percent of the time, some, as for example the people in Diskit only have a sad 4 hours of daily access. On top of that, this estimation does not account for the snowfalls in Spiti for example, where it is not uncommon to experience 3 consecutive days of powercut or more.
-As the Power Meter is supplied by the government, a solid 82 percent of the houses have a working power meter, if one assumes that the 13 percent who did not know whether they have a power meter, do have one, we can say that around 95% of the houses have a power meter.</p>
-<p>Another goal of the studies was to find out what would incline people to be caring and sharing with the available electricity, something rather unimaginable here in Germany.</p>
-<p>In general, the uninformed openness to delaying usage of electricity on a scale of 1-10 was around 5.5, with the additional information that a smart delay would cause an overall price reduction, the acceptance went up to 6.9, a good 14%. This implies that people would be a lot more inclined to give up conveniences if the benefits have a direct impact on them.</p>
+<p>Im Winter oder bei Regen sinkt die Qualität also deutlich – um über 30 %.<br />
+Im Durchschnitt haben Haushalte <strong>15,1 Stunden Strom pro Tag</strong> (≈ 63 %). Einige Regionen, wie Diskit, nur rund 4 Stunden.</p>
+<p>Etwa 95 % der Haushalte besitzen funktionierende Stromzähler.</p>
+<p>Ein weiteres Ziel war herauszufinden, <strong>was Menschen dazu bewegt, Strom zu teilen oder zu verschieben</strong>.<br />
+Ohne zusätzliche Information lag die Bereitschaft zur Verzögerung des Verbrauchs bei 5,5 / 10 – mit Aussicht auf Kostenvorteile stieg sie auf 6,9.</p>
<h2 id="Simulation">Simulation</h2>
-<p>After collecting all the estimated electric appliances of the local population, I simulated the use of 200 Solar Panels with 300Wp each, once for simultaneous electricity use, and once for mitigated electricity peaks through smart optimization and electricity usage delay.
-<img src="/images/sam_sim.png" alt="SAM Simulation of a local solar system " />
-<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimized" /></p>
-<p>Although solar is definitely not the optimal choice here and generates lots of issues with energy storage and battery charging at negative degrees, we figured that this was the way to go for the project.
-And as you can see, optimizing peak usage can improve solar from generating only one-fifth of the demand in winter to about half the demand in winter. Keeping in mind here, that the added solar farm was only intended to supply additional energy and not replace existing solutions, such a "small" farm would be a real lifesaver there and optimize the limited space in extremely mountainous terrain.</p>
-<h2 id="Closing_words">Closing words</h2>
-<p>There are to sides which the problems can be tackled: we can bring the total energy production up, by adding more panels or electricity by other means, but we can also try and bring the total demand down. This is to be achieved by investing strictly in the most energy-efficient appliances. Even replacing older, not-so-efficient appliances might sometimes be of use.
-But ensuring efficient use is not the only way to bring down the overall demand.</p>
-<p>As introduced as core ideas for the whole project, sharing and delaying will prove immensely useful. How so?
-By sharing, we mean a concept that is already widely applied in the relevant areas. What to do in a Village that has no access to water? Will we send each household out to the faraway river to catch water for their family? Or would we join hands in a community effort to dig a central well used by everyone?</p>
-<p>So, when we look at sharing electricity, how would we apply the concept? We take the appliances that consume the most energy individually and scale them up in order to increase efficiency. For example, in our case, that is most applicable to electric heating. If we manage to heat central community spaces available for everyone, naturally, fewer individual rooms will have to be heated. Similarly, one could declare a room as a public cinema, where people come together and watch Tv on a big Projector. Twice as fun, and conserving a great deal of energy again. Such ideas and others have to be realized in order to be able to match the total demand with the available supply.</p>
-<p>Sadly, the project was never taken up further, and the situation for the people in the Spiti Valley has not improved. Two years ago, a road directly through the mountains was finished, making the population hopeful for an increase in tourism, increasing the chances of the economic viability of improved solutions.
-I spent my time there in the function of a research intern, having no real say in the realization of the project. The problem remains, and I still think that decentral solutions look to be the most promising for this specific location. Of course, the Himalayas present a bit of an extreme location, but that doesn't change the fact that people live there and have a basic human right to electricity.</p>
+<p>Basierend auf den Daten simulierte ich den Einsatz von <strong>200 Solarmodulen à 300 Wp</strong>, einmal mit und einmal ohne intelligente Laststeuerung.</p>
+<p><img src="/images/sam_sim.png" alt="SAM Simulation eines lokalen Solarsystems" /><br />
+<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimiert" /></p>
+<p>Auch wenn Solar nicht optimal ist – vor allem wegen Kälte und Batterielagerung – zeigte sich, dass <strong>intelligente Lastverteilung</strong> den nutzbaren Ertrag im Winter von einem Fünftel auf etwa die Hälfte steigern kann.</p>
+<h2 id="Schlusswort">Schlusswort</h2>
+<p>Das Problem lässt sich aus zwei Richtungen angehen:</p>
+<ol>
+<li><strong>Produktion erhöhen</strong> – mehr Module, mehr Energiequellen.</li>
+<li><strong>Verbrauch senken</strong> – effizientere Geräte, gemeinschaftliche Nutzung.</li>
+</ol>
+<p>Das Konzept des <strong>Teilens und Verzögerns</strong> ist zentral. Wie bei einem gemeinschaftlich genutzten Brunnen kann auch Strom gemeinschaftlich erzeugt und genutzt werden.<br />
+Gemeinsam beheizte Räume oder öffentliche Projekträume sparen Energie und fördern Gemeinschaft.</p>
+<p>Leider wurde das Projekt nie weitergeführt, und die Situation im Spiti-Tal hat sich kaum verbessert. Eine neue Bergstraße gibt Hoffnung auf mehr Tourismus – und damit auf wirtschaftlich tragfähige Lösungen.</p>
+<p>Ich selbst war als Forschungspraktikant beteiligt, ohne Einfluss auf die Umsetzung. Dennoch bin ich überzeugt, dass <strong>dezentrale Lösungen</strong> der richtige Weg sind – gerade für extreme Regionen wie den Himalaya.<br />
+Denn eines bleibt wahr: <strong>Elektrizität ist ein Menschenrecht.</strong></p>

-<p>While learning about 3D Printing, I was most intrigued by the possibility to modify and repair existing products. While there is an amazing community with lots of good and free models around, naturally I came to a point where I did not find what I was looking for readily designed. I realized this is an essential skill for effectively operating not just 3D Printers, but any productive machine really.</p>
-<p>Since youtube was the place I was learning all about 3D Printing, and all the people that I looked up to there were using Fusion 360 as their CAD Program that’s what I got into.
-In hindsight, that was a pretty good choice and I am in love with the abilities parametric design gives me.
-Below you will find some of my designs.
-The process is something that I enjoy a lot and wish to dive into deeper.</p>
-<p>By trial and error, I already learned a lot about designing specifically for 3D Printing, but I often feel that there are many aesthetic considerations in design that I am not familiar with.
-I want to broaden my general ability to design physical objects, which is something I hope to gain during my master’s.</p>

+<p>Beim Erlernen des 3D-Drucks hat mich vor allem die Möglichkeit fasziniert, bestehende Produkte zu verändern oder zu reparieren.<br />
+Auch wenn es eine großartige Community mit vielen guten und kostenlosen Modellen gibt, bin ich schnell an den Punkt gekommen, an dem ich nicht fand, was ich suchte.<br />
+Mir wurde klar, dass dies eine wesentliche Fähigkeit ist, um nicht nur 3D-Drucker, sondern grundsätzlich jede Art von Produktionsmaschine sinnvoll zu nutzen.</p>
+<p>Da ich alles über 3D-Druck auf YouTube gelernt habe und dort fast alle mit <strong>Fusion 360</strong> arbeiteten, habe ich mich ebenfalls dafür entschieden.<br />
+Rückblickend war das eine sehr gute Wahl – ich habe mich in die Möglichkeiten des <strong>parametrischen Designs</strong> verliebt.<br />
+Unten findest du einige meiner Entwürfe.<br />
+Der Prozess selbst macht mir unglaublich viel Spaß und ich möchte ihn noch weiter vertiefen.</p>
+<p>Durch Ausprobieren habe ich bereits viel darüber gelernt, wie man speziell für den 3D-Druck konstruiert.<br />
+Trotzdem habe ich oft das Gefühl, dass mir ein tieferes Verständnis für <strong>ästhetische Gestaltung</strong> fehlt.<br />
+Ich möchte meine generelle Fähigkeit erweitern, physische Objekte zu entwerfen – etwas, das ich mir im Masterstudium erhoffe.</p>

-<p>Besides coming up with new objects, incorporating the real world is also an interest of mine.</p>
-<h3 id="Interaction_with_real_objects_and_environments">Interaction with real objects and environments</h3>
-<p>In the last few years I have played around with a few smartphone cameras and was always quite sad, that my scans were never quite accurate enough to do cool stuff with them.
-I could not really afford real 3D scanner and had already started cobbling together a raspberry Pi camera with a cheap TOF sensor, which is a simple, but not quite as good replacement for a laser or a lidar sensor, but then Apple came out with the first phones with accessible Lidar sensor.
-Recently, through work at the university I got access to a device with a lidar sensor and started having fun with it.
-See some examples here:</p>

-<p>This last one was scanned with just my smartphone camera. You can see that the quality is notably worse, but considering is was created with just a single, run-of-the-mill smartphone sensor, I think it is still pretty impressive and will certainly do something towards democratizing such technologies and abilities.</p>

+<p>Neben dem Entwerfen neuer Objekte interessiert mich auch die Integration der <strong>realen Welt</strong> in meine Arbeit.</p>
+<h3 id="Interaktion_mit_realen_Objekten_und_Umgebungen">Interaktion mit realen Objekten und Umgebungen</h3>
+<p>In den letzten Jahren habe ich mit verschiedenen Smartphone-Kameras experimentiert – leider waren meine Scans meist nicht präzise genug, um wirklich etwas damit anzufangen.<br />
+Ein professioneller 3D-Scanner war zu teuer, also bastelte ich mir eine Kombination aus einer <strong>Raspberry-Pi-Kamera</strong> und einem günstigen <strong>TOF-Sensor</strong>.<br />
+Das Setup ist simpel, aber bei weitem nicht so genau wie Laser- oder LiDAR-Sensoren. Dann brachte Apple die ersten Geräte mit <strong>zugänglichem LiDAR</strong> heraus.</p>
+<p>Durch meine Arbeit an der Universität hatte ich schließlich Zugriff auf ein Gerät mit LiDAR und begann, damit zu experimentieren.<br />
+Ein paar Beispiele siehst du hier:</p>

+<p>Der letzte Scan hier wurde nur mit einer <strong>Smartphone-Kamera</strong> erstellt.<br />
+Man erkennt deutlich, dass die Qualität geringer ist, aber angesichts der einfachen Technik finde ich das Ergebnis beeindruckend –<br />
+und es zeigt, wie sehr solche Technologien gerade <strong>demokratisiert</strong> werden.</p>

-<h2 id="Perspective">Perspective</h2>
-<p>What this section is supposed to deliver is the message that I am currently not where I want to be navigating the vast possibilities of CAD. I feel confident enough to approach small repairs around the flat with a new perspective, but I still lack technical expertise when approaching a collection composite parts, having to function together. I still have lots of projects halfdone or half-thought and one major reason is that there is no real critical exchange within my field of study.</p>
-<p>I want more than designing figurines or wearables.
-I want to incorporate 3D printing as a method to extend the abilities of other tools, have mechanical and electrical purposes, be foodsafe and engaging.
-I fell in love with the idea of designing a toy system, inspired by <a href="https://www.kickstarter.com/projects/makeway/makeway-create-intricate-courses-watch-your-marbles-soar">Makeways on Kickstarter</a>, I have already started adding my own parts to their set.</p>
-<p>I dream of my very own 3D printed coffeecup, one that is both foodsafe and dishwasher-surviving. For that, I would have to do quite a bit of material research, but that just makes the idea so much more appealing.
-I would love finding a material composition incorporating waste to stop relying on plastics, or at least on fossile plastics.
-Once in Berlin, I would want to talk to the people at <a href="https://www.kaffeeform.com/en/">Kaffeform</a> producing largely compostable Coffee Cups incorporating a significant amount of old ground espresso, albeit using injection molding for their process.
-The industry selling composite filaments is much more conservative with the percentage of non-plastic additives, because with a nozzle extrusion process there is much more to go wrong.
-Still, I would love to explore that avenue further and think there is a lot to be gained from looking at pellet printers.</p>
-<p>I also credit huge parts of my exploration process into local recycling to the awesome people at <a href="https://preciousplastic.com">Precious Plastic</a>, who I will join over the summer to learn more about their system.</p>
-<p>I find it hard to write anything about CAD without connecting it directly to a manufacturing process.
-And I believe that's a good thing. Always tying a design process to its realization, grounds the process and attaches to it some immediacy.</p>
-<p>For me to become more confident in this process, I am still missing more expertise in organic shapes, so I would be happy to dig more into Blender, an awesome tool that in my mind is far too powerful to dive into it with just youtube lessons.</p>

+<p>Was dieser Abschnitt zeigen soll: Ich bin beim Thema <strong>CAD</strong> noch nicht da, wo ich gerne wäre.<br />
+Ich fühle mich sicher genug, um kleine Reparaturen im Alltag anzugehen,<br />
+aber beim <strong>Konstruieren komplexer Bauteilgruppen</strong>, die zusammen funktionieren müssen, fehlt mir noch technisches Know-how.<br />
+Viele meiner Projekte sind halbfertig – einer der Hauptgründe ist der <strong>Mangel an fachlichem Austausch</strong> in meinem Umfeld.</p>
+<p>Ich möchte mehr als nur Figuren oder Wearables gestalten.<br />
+Ich möchte den <strong>3D-Druck als Werkzeugerweiterung</strong> nutzen –<br />
+für mechanische oder elektrische Anwendungen, lebensmittelechte Objekte, oder einfach Dinge, die begeistern.<br />
+Ich liebe die Idee, ein <strong>Baukastensystem</strong> zu entwickeln.<br />
+Inspiriert von <a href="https://www.kickstarter.com/projects/makeway/makeway-create-intricate-courses-watch-your-marbles-soar">Makeways auf Kickstarter</a> habe ich bereits angefangen, eigene Teile zu entwerfen.</p>
+<p>Ein Traum von mir ist eine <strong>eigene 3D-gedruckte Kaffeetasse</strong>, die sowohl <strong>spülmaschinenfest als auch lebensmittelecht</strong> ist.<br />
+Dafür müsste ich viel Materialforschung betreiben – aber genau das macht es spannend.<br />
+Ich möchte ein Material finden, das <strong>Abfälle</strong> einbezieht, um weniger von <strong>fossilen Kunststoffen</strong> abhängig zu sein.<br />
+In Berlin möchte ich mich mit den Leuten von <a href="https://www.kaffeeform.com/de/">Kaffeform</a> austauschen, die <strong>kompostierbare Becher</strong> aus gebrauchten Espressoresten herstellen (wenn auch per Spritzgussverfahren).</p>
+<p>Die Hersteller von <strong>Komposit-Filamenten</strong> sind bei der Beimischung nicht-plastischer Stoffe sehr vorsichtig,<br />
+weil der <strong>Extrusionsprozess</strong> durch Düsen leicht fehleranfällig ist.<br />
+Trotzdem glaube ich, dass gerade in diesem Bereich noch viel Potenzial steckt – besonders mit <strong>Pelletdruckern</strong>.</p>
+<p>Große Teile meiner Auseinandersetzung mit <strong>lokalem Recycling</strong> verdanke ich den großartigen Leuten von <a href="https://preciousplastic.com">Precious Plastic</a>, deren Open-Source-Designs mich sehr inspiriert haben.<br />
+Ich finde es schwer, über CAD zu schreiben, ohne gleichzeitig über den <strong>Herstellungsprozess</strong> zu sprechen –<br />
+und ich halte das für etwas Gutes.<br />
+Design und Umsetzung gehören für mich zusammen.</p>
+<p>Um noch sicherer zu werden, möchte ich mich stärker auf <strong>organische Formen</strong> konzentrieren.<br />
+Deshalb will ich tiefer in <strong>Blender</strong> einsteigen – ein großartiges Tool, das viel zu mächtig ist, um es nur über YouTube zu lernen.</p>

- <h2 id="2020:_discovering_jekyll">2020: discovering jekyll</h2>
-<p>For applying to my master's program in 2020, a portfolio was required, and since it was more or less for a design program, I wanted to have a nice website.
-After trying for a month to get what I wanted out of WordPress, and angrily quitting multiple times, I discovered <a href="https://jekyllrb.com">Jekyll</a>.
-Back then, <a href="https://gohugo.io">Hugo</a> and <a href="https://www.11ty.dev">11ty</a> were the newer kids on the block, but I was heavily relying on the free hosting from <a href="https://pages.github.com">GitHub Pages</a>, where Jekyll was the easiest to integrate.</p>
-<p>Back then, looking for inspiration, I had an ethics professor I really liked, and he had a Jekyll site with the <a href="https://mmistakes.github.io/minimal-mistakes/">Minimal Mistakes</a> theme.
-<a href="https://rainermuehlhoff.de">Prof. Mühlhoff</a></p>
-<p>I went about using Minimal Mistakes, and it was a great experience.
-The resulting portfolio at least got me into the master's, and I fell in love with the general idea of being able to write sites in markdown, while a program would take care of the rest.</p>
-<p>For years, Jekyll was my go-to for building static websites.
-It was familiar, widely supported, and part of the broader Ruby ecosystem.
-But over time, my frustrations grew—slow builds, complicated plugin setups, and a dependency stack that never felt quite right.
-To be honest, many of the drawbacks were totally not Jekyll’s fault. It was just slow, otherwise fine. But especially using GitHub Pages imposed quite a few limitations on plugins and themes.
-Also, maybe I didn’t put in enough effort, but I could never really get theme modifications working. Just extending the theme to show multiple authors was a pain—although it was eventually working.</p>
-<p>On now finishing the master's, I wanted a visual overhaul, and while browsing for inspiration again, using Jekyll at all got questioned again.
-I knew I wanted a static site generator, because markdown is the shit.
-So after looking around further, <strong><a href="https://www.getzola.org/">Zola</a></strong> emerged—actually through a chatbot suggestion 😄</p>
-<p>Recently, I made the leap to Zola, a Rust-powered static site generator, and I don't see myself going back.</p>
-<hr />
-<h2 id="rust_feels_right">rust feels right</h2>
-<p>I’ve always admired <a href="https://www.rust-lang.org/">Rust</a> for its speed, safety, and modern tooling.
-Using a static site generator built with Rust just made sense. <strong>Zola is fast</strong>—blazing fast.
-Even during local development, rebuilds are near-instant, and that alone makes the writing process smoother and more enjoyable.</p>
-<p>Plus, using something written in Rust means fewer external dependencies, no bundler hell, and zero Ruby setup headaches.
-I can just download the binary, run it, and get going. It respects my time.</p>
-<hr />
-<h2 id="zola_is_thoughtfully_designed">zola is thoughtfully designed</h2>
-<p>Beyond performance, Zola is just really well designed.
-Its template syntax (thanks to <a href="https://tera.netlify.app">Tera</a>) is more powerful and readable than Liquid.
-The built-in shortcodes, pagination, and asset pipelines all feel cohesive and purposeful.
-There’s very little “configuration over convention” fatigue that Jekyll often gave me.</p>
-<p>And even though both systems are markdown-based, migrating wasn’t just a matter of copy-pasting files.
-I had to rethink frontmatter, adjust templates, and wrangle image paths and shortcodes.
-The structure and behavior are different enough that it felt like a real rebuild—not just a port.</p>
-<hr />
-<h2 id="duckquill_made_me_switch">duckquill made me switch</h2>
-<p>The real catalyst, though? <a href="https://github.com/daudix/duckquill"><strong>Duckquill</strong></a>, a stunning Zola theme built by <a href="https://github.com/daudix">Daudix</a>.
-It struck the perfect balance between minimalism and elegance—exactly the aesthetic I wanted but could never quite achieve with Jekyll.
-Duckquill didn’t just make Zola usable for me; it made it <em>irresistible</em>.</p>
-<p>What really sets <strong>Duckquill</strong> apart—beyond its clean typography and smart layout—is how well it supports a vision of digital autonomy.
-The theme comes with <strong>Mastodon-powered comments</strong>, allowing for lightweight, federated interaction without relying on big centralized platforms.
-This fits perfectly with my goal of reclaiming control through <strong>self-hosting</strong>.
-Whether it's running my own site, owning my content, or interacting through the fediverse, Duckquill reinforces those values rather than working against them.
-It’s a rare example of design and infrastructure aligning with personal principles.</p>
-<hr />
-<h2 id="final_thoughts">final thoughts</h2>
-<p>Switching from Jekyll to Zola wasn’t effortless, but it was absolutely worth it.
-I now have a faster, more reliable, and better-looking site that’s easier to maintain and feels like it fits my tooling philosophy.</p>
-<p>If you're feeling the weight of your current setup, maybe it's time to try Zola—and give Duckquill a spin while you're at it.</p>

-<p>Access to Electricity is a basic human right. At first, that may seem over the top, but if one stops to think what all the little tasks that electricity can indirectly handle for us (lightning, laundry, cooking, freezing, heating, entertaining…) would consume in time and effort if we had to perform them manually, this idea becomes very clear. There are globally around 1 billion people without tier 2 access to electricity.</p>
-<p><a href="https://sdgs.un.org/goals/goal7">SDGS Goal 7</a></p>
-<p><img src="/assets/images/electricity_tiers.png" alt="The electricity tiers defined by the UN" /></p>
-<p>People only know the intensity of labor that goes into everything when there is no electricity. And it is not even only about convenience, electricity is an enormous lifesaver in any number of scenarios, think just of hospitals or mobile phone networks that would be rendered completely useless without it. So we can easily agree on a need, a demand for electricity globally, for every person. But what about the supply? Why is there 1 billion undersupplied?
-The Answer: missing profitability. It would be a charity project to supply every last person on earth, not a profitable one. And while charitable projects are noble and should be pursued, the reality within capitalism shows that this is not the way it is going to happen.
-But what if we could come up with technology, or rather, a communal structure, that enables us to supply profitably, and still adapt to both, the difficult external factors (weather issues, remoteness, altitude, etc.) and the smaller purses of the undersupplied?</p>
-<h3 id="Location">Location</h3>
-<p>Towards the end of 2018, I spent 4 months in northern India, on a research project with the IIT Kharagpur.
-The goal was to work on one of the 17 UN-defined sustainable development goals – electricity.</p>
-<p>Worldwide, an estimated 1 billion people have no or insubstantial access to the grid.
-Some of them live here, in the Key Monastery in the Spiti Valley at around 3500 meters altitude.</p>

+<p>Zugang zu Elektrizität ist ein grundlegendes Menschenrecht. Das mag zunächst übertrieben klingen, doch wenn man bedenkt, wie viele kleine Aufgaben der Strom uns indirekt abnimmt – Licht, Wäsche, Kochen, Kühlen, Heizen, Unterhaltung – wird schnell klar, wie viel Zeit und Aufwand ohne Elektrizität nötig wäre. Weltweit leben etwa <strong>eine Milliarde Menschen</strong> ohne Zugang zu Strom auf dem sogenannten Tier-2-Level.</p>

+Warum also sind immer noch so viele Menschen unterversorgt?<br />
+<strong>Die Antwort: fehlende Rentabilität.</strong> Es wäre ein wohltätiges, aber kein profitables Projekt, jede Person auf der Welt zu versorgen. Doch was, wenn wir eine Struktur finden könnten, die <strong>wirtschaftlich tragfähig</strong> ist und sich gleichzeitig an schwierige Bedingungen (Wetter, Abgeschiedenheit, Höhenlage) sowie an kleinere Einkommen anpassen kann?</p>

-<h2 id="The_Project">The Project</h2>
-<p>In an environment reliant on hydro-energy and solar (diesel transport is unreliable due to snowed-in mountain roads), over 6 months of snowy winter, frequent snowstorms, and temperatures of up to -35°C, securing the grid is hard.</p>
-<p>Our way to tackle the issue was to reject the in the western society very established notion of electricity as a homogenous product with centralized production and instead researched the possibilities of a predictive, self-correcting, and decentral grid.</p>
-<p>By prioritizing energy usage cases, instead of a full blackout during a storm, essential functions like radio towers and hospitals could be partially powered and maybe stay functioning. The binarity of either having electricity or not would be replaced by assigned quantities and timeslots, in a collective effort to be mindful and distribute the electricity necessity-based.
-The ultimate vision was a live predictive electricity market, where people could even earn money by selling their allotted, but not needed electricity.
-To gauge feasibility, I conducted several psychological acceptance studies and collected data on local electricity demands.
-I simulated a typical day of electricity demand in the Key monastery and the surrounding villages and mapped out the potential to install cost-efficient smart microgrid controllers enabling such an accurate and predictive behavior.
-The smart grid operator boxes available here in Germany cost several hundred, with installation several thousand Euros, not a feasible solution for the Indian population. Instead, we wanted to use Raspberry Pi's, which are interconnected through ethernet cables or local mesh networking.</p>

-<h2 id="Data_Collection">Data Collection</h2>
-<p>Building a questionnaire and visiting public schools during their English Classes, I had the chance to speak to a range of teenagers, answering questions about the state of electricity in their homes, generating more data than I could have accomplished running from door to door without any skills speaking local dialects. The questionnaire was as scientific as I could make it in such a situation and geared towards finding the type and number of electric devices in the homes and estimating typical usage scenarios.</p>
-<p>With a total of 145 participants from more than 6 different schools and roughly 4 different districts, all located in the Indian part of the Himalayas, the findings are as follows:</p>
-<p>The participants range from 11 to 53 years, with an average of 17 years.
-The average household has 6 members with an average of 5 smart devices. Only 2 percent of the Households had not a single smart device, but at the same time, only 42 percent had direct or indirect access to a laptop or computer. So the main body of smart devices consists of smartphones with a negligible portion of tablets.
-The average total amount of electrical devices is around 11 electrical appliances per house.</p>
-<p><strong>Subjective</strong> Quality Rating on a scale of 1 to 10:</p>
+<p>Das ist <strong>Tashi Gang</strong>, ein Dorf nahe des Klosters. Es beherbergt rund 50 Menschen und ist nur drei bis vier Monate im Sommer über eine Straße erreichbar.

+<h2 id="Das_Projekt">Das Projekt</h2>
+<p>In einer Umgebung, die auf Wasser- und Sonnenenergie angewiesen ist, mit über sechs Monaten Schnee, häufigen Schneestürmen und Temperaturen bis zu –35 °C, ist die Netzsicherung schwierig.</p>
+<p>Unser Ansatz war es, die im Westen etablierte Vorstellung von Elektrizität als homogenes, zentral erzeugtes Produkt zu hinterfragen und stattdessen die Möglichkeiten eines <strong>prädiktiven, sich selbst korrigierenden und dezentralen Netzes</strong> zu erforschen.</p>
+<p>Anstatt bei einem Sturm einen kompletten Blackout zu riskieren, könnten bei einer Priorisierung der Energieverwendung wichtige Funktionen – etwa Radiotürme oder Krankenhäuser – teilweise weiterbetrieben werden. Die Binarität von Strom / kein Strom würde durch ein System von <strong>Zuteilungen nach Bedarf und Zeitfenstern</strong> ersetzt.<br />
+Langfristig war die Vision ein <strong>lokaler, prädiktiver Strommarkt</strong>, bei dem Menschen überschüssige Energie verkaufen können.</p>
+<p>Zur Machbarkeitsprüfung führte ich psychologische Akzeptanzstudien durch und sammelte Daten zum lokalen Stromverbrauch. Anschließend simulierte ich einen typischen Strombedarfstag im Key-Kloster und in den umliegenden Dörfern und entwickelte Konzepte für kostengünstige <strong>Smart-Microgrid-Controller</strong>.</p>
+<p>Die hier in Deutschland verfügbaren Netzsteuerboxen kosten mehrere Hundert bis Tausend Euro – keine realistische Lösung für die Bevölkerung vor Ort. Stattdessen planten wir <strong>Raspberry Pi-basierte Systeme</strong>, vernetzt über Ethernet oder lokale Mesh-Netze.</p>
+<h2 id="Forschung">Forschung</h2>
+<p><img src="/images/Key_Monastery_Spiti.png" alt="Das Stromnetz des Key-Klosters" /></p>
+<h2 id="Datenerhebung">Datenerhebung</h2>
+<p>Durch den Besuch öffentlicher Schulen im Englischunterricht konnte ich mit Jugendlichen über den Stromzustand in ihren Haushalten sprechen und umfangreiche Daten erheben. Insgesamt nahmen <strong>145 Teilnehmer aus über sechs Schulen</strong> in etwa <strong>vier Distrikten</strong> teil – alle im indischen Himalaya.</p>
+<p>Der Altersdurchschnitt lag bei 17 Jahren. Durchschnittlich leben 6 Personen pro Haushalt mit etwa 5 Smart-Geräten. Nur 2 % der Haushalte hatten gar keine, 42 % verfügten über Computer oder Laptops.</p>
<blockquote>
-<p>Average quality in summer: 7.1
-Average quality in monsoon: 5.6
-Average quality in autumn: 7.1
-Average quality in winter: 4.0</p>
+<p>Durchschnittliche Stromqualität (1 – 10):<br />
+Sommer: 7,1 Monsun: 5,6 Herbst: 7,1 Winter: 4,0</p>
</blockquote>
-<p>So, as you would expect, during winter, but also when it rains, the felt quality drops by more than 30 percent on average.
-As for the daily supply time, the average sits at 15.1 hours out of 24, meaning the people have electricity only for 62.9 percent of the time, some, as for example the people in Diskit only have a sad 4 hours of daily access. On top of that, this estimation does not account for the snowfalls in Spiti for example, where it is not uncommon to experience 3 consecutive days of powercut or more.
-As the Power Meter is supplied by the government, a solid 82 percent of the houses have a working power meter, if one assumes that the 13 percent who did not know whether they have a power meter, do have one, we can say that around 95% of the houses have a power meter.</p>
-<p>Another goal of the studies was to find out what would incline people to be caring and sharing with the available electricity, something rather unimaginable here in Germany.</p>
-<p>In general, the uninformed openness to delaying usage of electricity on a scale of 1-10 was around 5.5, with the additional information that a smart delay would cause an overall price reduction, the acceptance went up to 6.9, a good 14%. This implies that people would be a lot more inclined to give up conveniences if the benefits have a direct impact on them.</p>
+<p>Im Winter oder bei Regen sinkt die Qualität also deutlich – um über 30 %.<br />
+Im Durchschnitt haben Haushalte <strong>15,1 Stunden Strom pro Tag</strong> (≈ 63 %). Einige Regionen, wie Diskit, nur rund 4 Stunden.</p>
+<p>Etwa 95 % der Haushalte besitzen funktionierende Stromzähler.</p>
+<p>Ein weiteres Ziel war herauszufinden, <strong>was Menschen dazu bewegt, Strom zu teilen oder zu verschieben</strong>.<br />
+Ohne zusätzliche Information lag die Bereitschaft zur Verzögerung des Verbrauchs bei 5,5 / 10 – mit Aussicht auf Kostenvorteile stieg sie auf 6,9.</p>
<h2 id="Simulation">Simulation</h2>
-<p>After collecting all the estimated electric appliances of the local population, I simulated the use of 200 Solar Panels with 300Wp each, once for simultaneous electricity use, and once for mitigated electricity peaks through smart optimization and electricity usage delay.
-<img src="/images/sam_sim.png" alt="SAM Simulation of a local solar system " />
-<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimized" /></p>
-<p>Although solar is definitely not the optimal choice here and generates lots of issues with energy storage and battery charging at negative degrees, we figured that this was the way to go for the project.
-And as you can see, optimizing peak usage can improve solar from generating only one-fifth of the demand in winter to about half the demand in winter. Keeping in mind here, that the added solar farm was only intended to supply additional energy and not replace existing solutions, such a "small" farm would be a real lifesaver there and optimize the limited space in extremely mountainous terrain.</p>
-<h2 id="Closing_words">Closing words</h2>
-<p>There are to sides which the problems can be tackled: we can bring the total energy production up, by adding more panels or electricity by other means, but we can also try and bring the total demand down. This is to be achieved by investing strictly in the most energy-efficient appliances. Even replacing older, not-so-efficient appliances might sometimes be of use.
-But ensuring efficient use is not the only way to bring down the overall demand.</p>
-<p>As introduced as core ideas for the whole project, sharing and delaying will prove immensely useful. How so?
-By sharing, we mean a concept that is already widely applied in the relevant areas. What to do in a Village that has no access to water? Will we send each household out to the faraway river to catch water for their family? Or would we join hands in a community effort to dig a central well used by everyone?</p>
-<p>So, when we look at sharing electricity, how would we apply the concept? We take the appliances that consume the most energy individually and scale them up in order to increase efficiency. For example, in our case, that is most applicable to electric heating. If we manage to heat central community spaces available for everyone, naturally, fewer individual rooms will have to be heated. Similarly, one could declare a room as a public cinema, where people come together and watch Tv on a big Projector. Twice as fun, and conserving a great deal of energy again. Such ideas and others have to be realized in order to be able to match the total demand with the available supply.</p>
-<p>Sadly, the project was never taken up further, and the situation for the people in the Spiti Valley has not improved. Two years ago, a road directly through the mountains was finished, making the population hopeful for an increase in tourism, increasing the chances of the economic viability of improved solutions.
-I spent my time there in the function of a research intern, having no real say in the realization of the project. The problem remains, and I still think that decentral solutions look to be the most promising for this specific location. Of course, the Himalayas present a bit of an extreme location, but that doesn't change the fact that people live there and have a basic human right to electricity.</p>
+<p>Basierend auf den Daten simulierte ich den Einsatz von <strong>200 Solarmodulen à 300 Wp</strong>, einmal mit und einmal ohne intelligente Laststeuerung.</p>
+<p><img src="/images/sam_sim.png" alt="SAM Simulation eines lokalen Solarsystems" /><br />
+<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimiert" /></p>
+<p>Auch wenn Solar nicht optimal ist – vor allem wegen Kälte und Batterielagerung – zeigte sich, dass <strong>intelligente Lastverteilung</strong> den nutzbaren Ertrag im Winter von einem Fünftel auf etwa die Hälfte steigern kann.</p>
+<h2 id="Schlusswort">Schlusswort</h2>
+<p>Das Problem lässt sich aus zwei Richtungen angehen:</p>
+<ol>
+<li><strong>Produktion erhöhen</strong> – mehr Module, mehr Energiequellen.</li>
+<li><strong>Verbrauch senken</strong> – effizientere Geräte, gemeinschaftliche Nutzung.</li>
+</ol>
+<p>Das Konzept des <strong>Teilens und Verzögerns</strong> ist zentral. Wie bei einem gemeinschaftlich genutzten Brunnen kann auch Strom gemeinschaftlich erzeugt und genutzt werden.<br />
+Gemeinsam beheizte Räume oder öffentliche Projekträume sparen Energie und fördern Gemeinschaft.</p>
+<p>Leider wurde das Projekt nie weitergeführt, und die Situation im Spiti-Tal hat sich kaum verbessert. Eine neue Bergstraße gibt Hoffnung auf mehr Tourismus – und damit auf wirtschaftlich tragfähige Lösungen.</p>
+<p>Ich selbst war als Forschungspraktikant beteiligt, ohne Einfluss auf die Umsetzung. Dennoch bin ich überzeugt, dass <strong>dezentrale Lösungen</strong> der richtige Weg sind – gerade für extreme Regionen wie den Himalaya.<br />
+Denn eines bleibt wahr: <strong>Elektrizität ist ein Menschenrecht.</strong></p>

-<p>Access to Electricity is a basic human right. At first, that may seem over the top, but if one stops to think what all the little tasks that electricity can indirectly handle for us (lightning, laundry, cooking, freezing, heating, entertaining…) would consume in time and effort if we had to perform them manually, this idea becomes very clear. There are globally around 1 billion people without tier 2 access to electricity.</p>

-<p>People only know the intensity of labor that goes into everything when there is no electricity. And it is not even only about convenience, electricity is an enormous lifesaver in any number of scenarios, think just of hospitals or mobile phone networks that would be rendered completely useless without it. So we can easily agree on a need, a demand for electricity globally, for every person. But what about the supply? Why is there 1 billion undersupplied?
-The Answer: missing profitability. It would be a charity project to supply every last person on earth, not a profitable one. And while charitable projects are noble and should be pursued, the reality within capitalism shows that this is not the way it is going to happen.
-But what if we could come up with technology, or rather, a communal structure, that enables us to supply profitably, and still adapt to both, the difficult external factors (weather issues, remoteness, altitude, etc.) and the smaller purses of the undersupplied?</p>

+<p>Zugang zu Elektrizität ist ein grundlegendes Menschenrecht.

-<h2 id="The_Project">The Project</h2>
-<p>In an environment reliant on hydro-energy and solar (diesel transport is unreliable due to snowed-in mountain roads), over 6 months of snowy winter, frequent snowstorms, and temperatures of up to -35°C, securing the grid is hard.</p>
-<p>Our way to tackle the issue was to reject the in the western society very established notion of electricity as a homogenous product with centralized production and instead researched the possibilities of a predictive, self-correcting, and decentral grid.</p>
-<p>By prioritizing energy usage cases, instead of a full blackout during a storm, essential functions like radio towers and hospitals could be partially powered and maybe stay functioning. The binarity of either having electricity or not would be replaced by assigned quantities and timeslots, in a collective effort to be mindful and distribute the electricity necessity-based.
-The ultimate vision was a live predictive electricity market, where people could even earn money by selling their allotted, but not needed electricity.
-To gauge feasibility, I conducted several psychological acceptance studies and collected data on local electricity demands.
-I simulated a typical day of electricity demand in the Key monastery and the surrounding villages and mapped out the potential to install cost-efficient smart microgrid controllers enabling such an accurate and predictive behavior.
-The smart grid operator boxes available here in Germany cost several hundred, with installation several thousand Euros, not a feasible solution for the Indian population. Instead, we wanted to use Raspberry Pi's, which are interconnected through ethernet cables or local mesh networking.</p>

-<h2 id="Data_Collection">Data Collection</h2>
-<p>Building a questionnaire and visiting public schools during their English Classes, I had the chance to speak to a range of teenagers, answering questions about the state of electricity in their homes, generating more data than I could have accomplished running from door to door without any skills speaking local dialects. The questionnaire was as scientific as I could make it in such a situation and geared towards finding the type and number of electric devices in the homes and estimating typical usage scenarios.</p>
-<p>With a total of 145 participants from more than 6 different schools and roughly 4 different districts, all located in the Indian part of the Himalayas, the findings are as follows:</p>
-<p>The participants range from 11 to 53 years, with an average of 17 years.
-The average household has 6 members with an average of 5 smart devices. Only 2 percent of the Households had not a single smart device, but at the same time, only 42 percent had direct or indirect access to a laptop or computer. So the main body of smart devices consists of smartphones with a negligible portion of tablets.
-The average total amount of electrical devices is around 11 electrical appliances per house.</p>
-<p><strong>Subjective</strong> Quality Rating on a scale of 1 to 10:</p>
+<p>Das ist <strong>Tashi Gang</strong>, ein Dorf nahe des Klosters. Es beherbergt rund 50 Menschen und ist nur drei bis vier Monate im Sommer über eine Straße erreichbar.

+<h2 id="Das_Projekt">Das Projekt</h2>
+<p>In einer Umgebung, die auf Wasser- und Sonnenenergie angewiesen ist, mit über sechs Monaten Schnee, häufigen Schneestürmen und Temperaturen bis zu –35 °C, ist die Netzsicherung schwierig.</p>
+<p>Unser Ansatz war es, die im Westen etablierte Vorstellung von Elektrizität als homogenes, zentral erzeugtes Produkt zu hinterfragen und stattdessen die Möglichkeiten eines <strong>prädiktiven, sich selbst korrigierenden und dezentralen Netzes</strong> zu erforschen.</p>
+<p>Anstatt bei einem Sturm einen kompletten Blackout zu riskieren, könnten bei einer Priorisierung der Energieverwendung wichtige Funktionen – etwa Radiotürme oder Krankenhäuser – teilweise weiterbetrieben werden. Die Binarität von Strom / kein Strom würde durch ein System von <strong>Zuteilungen nach Bedarf und Zeitfenstern</strong> ersetzt.<br />
+Langfristig war die Vision ein <strong>lokaler, prädiktiver Strommarkt</strong>, bei dem Menschen überschüssige Energie verkaufen können.</p>
+<p>Zur Machbarkeitsprüfung führte ich psychologische Akzeptanzstudien durch und sammelte Daten zum lokalen Stromverbrauch. Anschließend simulierte ich einen typischen Strombedarfstag im Key-Kloster und in den umliegenden Dörfern und entwickelte Konzepte für kostengünstige <strong>Smart-Microgrid-Controller</strong>.</p>
+<p>Die hier in Deutschland verfügbaren Netzsteuerboxen kosten mehrere Hundert bis Tausend Euro – keine realistische Lösung für die Bevölkerung vor Ort. Stattdessen planten wir <strong>Raspberry Pi-basierte Systeme</strong>, vernetzt über Ethernet oder lokale Mesh-Netze.</p>
+<h2 id="Forschung">Forschung</h2>
+<p><img src="/images/Key_Monastery_Spiti.png" alt="Das Stromnetz des Key-Klosters" /></p>
+<h2 id="Datenerhebung">Datenerhebung</h2>
+<p>Durch den Besuch öffentlicher Schulen im Englischunterricht konnte ich mit Jugendlichen über den Stromzustand in ihren Haushalten sprechen und umfangreiche Daten erheben. Insgesamt nahmen <strong>145 Teilnehmer aus über sechs Schulen</strong> in etwa <strong>vier Distrikten</strong> teil – alle im indischen Himalaya.</p>
+<p>Der Altersdurchschnitt lag bei 17 Jahren. Durchschnittlich leben 6 Personen pro Haushalt mit etwa 5 Smart-Geräten. Nur 2 % der Haushalte hatten gar keine, 42 % verfügten über Computer oder Laptops.</p>
<blockquote>
-<p>Average quality in summer: 7.1
-Average quality in monsoon: 5.6
-Average quality in autumn: 7.1
-Average quality in winter: 4.0</p>
+<p>Durchschnittliche Stromqualität (1 – 10):<br />
+Sommer: 7,1 Monsun: 5,6 Herbst: 7,1 Winter: 4,0</p>
</blockquote>
-<p>So, as you would expect, during winter, but also when it rains, the felt quality drops by more than 30 percent on average.
-As for the daily supply time, the average sits at 15.1 hours out of 24, meaning the people have electricity only for 62.9 percent of the time, some, as for example the people in Diskit only have a sad 4 hours of daily access. On top of that, this estimation does not account for the snowfalls in Spiti for example, where it is not uncommon to experience 3 consecutive days of powercut or more.
-As the Power Meter is supplied by the government, a solid 82 percent of the houses have a working power meter, if one assumes that the 13 percent who did not know whether they have a power meter, do have one, we can say that around 95% of the houses have a power meter.</p>
-<p>Another goal of the studies was to find out what would incline people to be caring and sharing with the available electricity, something rather unimaginable here in Germany.</p>
-<p>In general, the uninformed openness to delaying usage of electricity on a scale of 1-10 was around 5.5, with the additional information that a smart delay would cause an overall price reduction, the acceptance went up to 6.9, a good 14%. This implies that people would be a lot more inclined to give up conveniences if the benefits have a direct impact on them.</p>
+<p>Im Winter oder bei Regen sinkt die Qualität also deutlich – um über 30 %.<br />
+Im Durchschnitt haben Haushalte <strong>15,1 Stunden Strom pro Tag</strong> (≈ 63 %). Einige Regionen, wie Diskit, nur rund 4 Stunden.</p>
+<p>Etwa 95 % der Haushalte besitzen funktionierende Stromzähler.</p>
+<p>Ein weiteres Ziel war herauszufinden, <strong>was Menschen dazu bewegt, Strom zu teilen oder zu verschieben</strong>.<br />
+Ohne zusätzliche Information lag die Bereitschaft zur Verzögerung des Verbrauchs bei 5,5 / 10 – mit Aussicht auf Kostenvorteile stieg sie auf 6,9.</p>
<h2 id="Simulation">Simulation</h2>
-<p>After collecting all the estimated electric appliances of the local population, I simulated the use of 200 Solar Panels with 300Wp each, once for simultaneous electricity use, and once for mitigated electricity peaks through smart optimization and electricity usage delay.
-<img src="/images/sam_sim.png" alt="SAM Simulation of a local solar system " />
-<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimized" /></p>
-<p>Although solar is definitely not the optimal choice here and generates lots of issues with energy storage and battery charging at negative degrees, we figured that this was the way to go for the project.
-And as you can see, optimizing peak usage can improve solar from generating only one-fifth of the demand in winter to about half the demand in winter. Keeping in mind here, that the added solar farm was only intended to supply additional energy and not replace existing solutions, such a "small" farm would be a real lifesaver there and optimize the limited space in extremely mountainous terrain.</p>
-<h2 id="Closing_words">Closing words</h2>
-<p>There are to sides which the problems can be tackled: we can bring the total energy production up, by adding more panels or electricity by other means, but we can also try and bring the total demand down. This is to be achieved by investing strictly in the most energy-efficient appliances. Even replacing older, not-so-efficient appliances might sometimes be of use.
-But ensuring efficient use is not the only way to bring down the overall demand.</p>
-<p>As introduced as core ideas for the whole project, sharing and delaying will prove immensely useful. How so?
-By sharing, we mean a concept that is already widely applied in the relevant areas. What to do in a Village that has no access to water? Will we send each household out to the faraway river to catch water for their family? Or would we join hands in a community effort to dig a central well used by everyone?</p>
-<p>So, when we look at sharing electricity, how would we apply the concept? We take the appliances that consume the most energy individually and scale them up in order to increase efficiency. For example, in our case, that is most applicable to electric heating. If we manage to heat central community spaces available for everyone, naturally, fewer individual rooms will have to be heated. Similarly, one could declare a room as a public cinema, where people come together and watch Tv on a big Projector. Twice as fun, and conserving a great deal of energy again. Such ideas and others have to be realized in order to be able to match the total demand with the available supply.</p>
-<p>Sadly, the project was never taken up further, and the situation for the people in the Spiti Valley has not improved. Two years ago, a road directly through the mountains was finished, making the population hopeful for an increase in tourism, increasing the chances of the economic viability of improved solutions.
-I spent my time there in the function of a research intern, having no real say in the realization of the project. The problem remains, and I still think that decentral solutions look to be the most promising for this specific location. Of course, the Himalayas present a bit of an extreme location, but that doesn't change the fact that people live there and have a basic human right to electricity.</p>
+<p>Basierend auf den Daten simulierte ich den Einsatz von <strong>200 Solarmodulen à 300 Wp</strong>, einmal mit und einmal ohne intelligente Laststeuerung.</p>
+<p><img src="/images/sam_sim.png" alt="SAM Simulation eines lokalen Solarsystems" /><br />
+<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimiert" /></p>
+<p>Auch wenn Solar nicht optimal ist – vor allem wegen Kälte und Batterielagerung – zeigte sich, dass <strong>intelligente Lastverteilung</strong> den nutzbaren Ertrag im Winter von einem Fünftel auf etwa die Hälfte steigern kann.</p>
+<h2 id="Schlusswort">Schlusswort</h2>
+<p>Das Problem lässt sich aus zwei Richtungen angehen:</p>
+<ol>
+<li><strong>Produktion erhöhen</strong> – mehr Module, mehr Energiequellen.</li>
+<li><strong>Verbrauch senken</strong> – effizientere Geräte, gemeinschaftliche Nutzung.</li>
+</ol>
+<p>Das Konzept des <strong>Teilens und Verzögerns</strong> ist zentral. Wie bei einem gemeinschaftlich genutzten Brunnen kann auch Strom gemeinschaftlich erzeugt und genutzt werden.<br />
+Gemeinsam beheizte Räume oder öffentliche Projekträume sparen Energie und fördern Gemeinschaft.</p>
+<p>Leider wurde das Projekt nie weitergeführt, und die Situation im Spiti-Tal hat sich kaum verbessert. Eine neue Bergstraße gibt Hoffnung auf mehr Tourismus – und damit auf wirtschaftlich tragfähige Lösungen.</p>
+<p>Ich selbst war als Forschungspraktikant beteiligt, ohne Einfluss auf die Umsetzung. Dennoch bin ich überzeugt, dass <strong>dezentrale Lösungen</strong> der richtige Weg sind – gerade für extreme Regionen wie den Himalaya.<br />
+Denn eines bleibt wahr: <strong>Elektrizität ist ein Menschenrecht.</strong></p>

- <h2 id="2020:_discovering_jekyll">2020: discovering jekyll</h2>
-<p>For applying to my master's program in 2020, a portfolio was required, and since it was more or less for a design program, I wanted to have a nice website.
-After trying for a month to get what I wanted out of WordPress, and angrily quitting multiple times, I discovered <a href="https://jekyllrb.com">Jekyll</a>.
-Back then, <a href="https://gohugo.io">Hugo</a> and <a href="https://www.11ty.dev">11ty</a> were the newer kids on the block, but I was heavily relying on the free hosting from <a href="https://pages.github.com">GitHub Pages</a>, where Jekyll was the easiest to integrate.</p>
-<p>Back then, looking for inspiration, I had an ethics professor I really liked, and he had a Jekyll site with the <a href="https://mmistakes.github.io/minimal-mistakes/">Minimal Mistakes</a> theme.
-<a href="https://rainermuehlhoff.de">Prof. Mühlhoff</a></p>
-<p>I went about using Minimal Mistakes, and it was a great experience.
-The resulting portfolio at least got me into the master's, and I fell in love with the general idea of being able to write sites in markdown, while a program would take care of the rest.</p>
-<p>For years, Jekyll was my go-to for building static websites.
-It was familiar, widely supported, and part of the broader Ruby ecosystem.
-But over time, my frustrations grew—slow builds, complicated plugin setups, and a dependency stack that never felt quite right.
-To be honest, many of the drawbacks were totally not Jekyll’s fault. It was just slow, otherwise fine. But especially using GitHub Pages imposed quite a few limitations on plugins and themes.
-Also, maybe I didn’t put in enough effort, but I could never really get theme modifications working. Just extending the theme to show multiple authors was a pain—although it was eventually working.</p>
-<p>On now finishing the master's, I wanted a visual overhaul, and while browsing for inspiration again, using Jekyll at all got questioned again.
-I knew I wanted a static site generator, because markdown is the shit.
-So after looking around further, <strong><a href="https://www.getzola.org/">Zola</a></strong> emerged—actually through a chatbot suggestion 😄</p>
-<p>Recently, I made the leap to Zola, a Rust-powered static site generator, and I don't see myself going back.</p>
-<hr />
-<h2 id="rust_feels_right">rust feels right</h2>
-<p>I’ve always admired <a href="https://www.rust-lang.org/">Rust</a> for its speed, safety, and modern tooling.
-Using a static site generator built with Rust just made sense. <strong>Zola is fast</strong>—blazing fast.
-Even during local development, rebuilds are near-instant, and that alone makes the writing process smoother and more enjoyable.</p>
-<p>Plus, using something written in Rust means fewer external dependencies, no bundler hell, and zero Ruby setup headaches.
-I can just download the binary, run it, and get going. It respects my time.</p>
-<hr />
-<h2 id="zola_is_thoughtfully_designed">zola is thoughtfully designed</h2>
-<p>Beyond performance, Zola is just really well designed.
-Its template syntax (thanks to <a href="https://tera.netlify.app">Tera</a>) is more powerful and readable than Liquid.
-The built-in shortcodes, pagination, and asset pipelines all feel cohesive and purposeful.
-There’s very little “configuration over convention” fatigue that Jekyll often gave me.</p>
-<p>And even though both systems are markdown-based, migrating wasn’t just a matter of copy-pasting files.
-I had to rethink frontmatter, adjust templates, and wrangle image paths and shortcodes.
-The structure and behavior are different enough that it felt like a real rebuild—not just a port.</p>
-<hr />
-<h2 id="duckquill_made_me_switch">duckquill made me switch</h2>
-<p>The real catalyst, though? <a href="https://github.com/daudix/duckquill"><strong>Duckquill</strong></a>, a stunning Zola theme built by <a href="https://github.com/daudix">Daudix</a>.
-It struck the perfect balance between minimalism and elegance—exactly the aesthetic I wanted but could never quite achieve with Jekyll.
-Duckquill didn’t just make Zola usable for me; it made it <em>irresistible</em>.</p>
-<p>What really sets <strong>Duckquill</strong> apart—beyond its clean typography and smart layout—is how well it supports a vision of digital autonomy.
-The theme comes with <strong>Mastodon-powered comments</strong>, allowing for lightweight, federated interaction without relying on big centralized platforms.
-This fits perfectly with my goal of reclaiming control through <strong>self-hosting</strong>.
-Whether it's running my own site, owning my content, or interacting through the fediverse, Duckquill reinforces those values rather than working against them.
-It’s a rare example of design and infrastructure aligning with personal principles.</p>
-<hr />
-<h2 id="final_thoughts">final thoughts</h2>
-<p>Switching from Jekyll to Zola wasn’t effortless, but it was absolutely worth it.
-I now have a faster, more reliable, and better-looking site that’s easier to maintain and feels like it fits my tooling philosophy.</p>
-<p>If you're feeling the weight of your current setup, maybe it's time to try Zola—and give Duckquill a spin while you're at it.</p>

-The Answer: missing profitability. It would be a charity project to supply every last person on earth, not a profitable one. And while charitable projects are noble and should be pursued, the reality within capitalism shows that this is not the way it is going to happen.
-But what if we could come up with technology, or rather, a communal structure, that enables us to supply profitably, and still adapt to both, the difficult external factors (weather issues, remoteness, altitude, etc.) and the smaller purses of the undersupplied?</p>

+<p>Zugang zu Elektrizität ist ein grundlegendes Menschenrecht. Das mag zunächst übertrieben klingen, doch wenn man bedenkt, wie viele kleine Aufgaben der Strom uns indirekt abnimmt – Licht, Wäsche, Kochen, Kühlen, Heizen, Unterhaltung – wird schnell klar, wie viel Zeit und Aufwand ohne Elektrizität nötig wäre. Weltweit leben etwa <strong>eine Milliarde Menschen</strong> ohne Zugang zu Strom auf dem sogenannten Tier-2-Level.</p>

+Warum also sind immer noch so viele Menschen unterversorgt?<br />
+<strong>Die Antwort: fehlende Rentabilität.</strong> Es wäre ein wohltätiges, aber kein profitables Projekt, jede Person auf der Welt zu versorgen.

-<h2 id="The_Project">The Project</h2>
-<p>In an environment reliant on hydro-energy and solar (diesel transport is unreliable due to snowed-in mountain roads), over 6 months of snowy winter, frequent snowstorms, and temperatures of up to -35°C, securing the grid is hard.</p>
-<p>Our way to tackle the issue was to reject the in the western society very established notion of electricity as a homogenous product with centralized production and instead researched the possibilities of a predictive, self-correcting, and decentral grid.</p>
-<p>By prioritizing energy usage cases, instead of a full blackout during a storm, essential functions like radio towers and hospitals could be partially powered and maybe stay functioning. The binarity of either having electricity or not would be replaced by assigned quantities and timeslots, in a collective effort to be mindful and distribute the electricity necessity-based.
-The ultimate vision was a live predictive electricity market, where people could even earn money by selling their allotted, but not needed electricity.
-To gauge feasibility, I conducted several psychological acceptance studies and collected data on local electricity demands.
-I simulated a typical day of electricity demand in the Key monastery and the surrounding villages and mapped out the potential to install cost-efficient smart microgrid controllers enabling such an accurate and predictive behavior.
-The smart grid operator boxes available here in Germany cost several hundred, with installation several thousand Euros, not a feasible solution for the Indian population. Instead, we wanted to use Raspberry Pi's, which are interconnected through ethernet cables or local mesh networking.</p>

-<h2 id="Data_Collection">Data Collection</h2>
-<p>Building a questionnaire and visiting public schools during their English Classes, I had the chance to speak to a range of teenagers, answering questions about the state of electricity in their homes, generating more data than I could have accomplished running from door to door without any skills speaking local dialects. The questionnaire was as scientific as I could make it in such a situation and geared towards finding the type and number of electric devices in the homes and estimating typical usage scenarios.</p>
-<p>With a total of 145 participants from more than 6 different schools and roughly 4 different districts, all located in the Indian part of the Himalayas, the findings are as follows:</p>
-<p>The participants range from 11 to 53 years, with an average of 17 years.
-The average household has 6 members with an average of 5 smart devices. Only 2 percent of the Households had not a single smart device, but at the same time, only 42 percent had direct or indirect access to a laptop or computer. So the main body of smart devices consists of smartphones with a negligible portion of tablets.
-The average total amount of electrical devices is around 11 electrical appliances per house.</p>
-<p><strong>Subjective</strong> Quality Rating on a scale of 1 to 10:</p>
+<p>Das ist <strong>Tashi Gang</strong>, ein Dorf nahe des Klosters. Es beherbergt rund 50 Menschen und ist nur drei bis vier Monate im Sommer über eine Straße erreichbar.

+<h2 id="Das_Projekt">Das Projekt</h2>
+<p>In einer Umgebung, die auf Wasser- und Sonnenenergie angewiesen ist, mit über sechs Monaten Schnee, häufigen Schneestürmen und Temperaturen bis zu –35 °C, ist die Netzsicherung schwierig.</p>
+<p>Unser Ansatz war es, die im Westen etablierte Vorstellung von Elektrizität als homogenes, zentral erzeugtes Produkt zu hinterfragen und stattdessen die Möglichkeiten eines <strong>prädiktiven, sich selbst korrigierenden und dezentralen Netzes</strong> zu erforschen.</p>
+<p>Anstatt bei einem Sturm einen kompletten Blackout zu riskieren, könnten bei einer Priorisierung der Energieverwendung wichtige Funktionen – etwa Radiotürme oder Krankenhäuser – teilweise weiterbetrieben werden. Die Binarität von Strom / kein Strom würde durch ein System von <strong>Zuteilungen nach Bedarf und Zeitfenstern</strong> ersetzt.<br />
+Langfristig war die Vision ein <strong>lokaler, prädiktiver Strommarkt</strong>, bei dem Menschen überschüssige Energie verkaufen können.</p>
+<p>Zur Machbarkeitsprüfung führte ich psychologische Akzeptanzstudien durch und sammelte Daten zum lokalen Stromverbrauch. Anschließend simulierte ich einen typischen Strombedarfstag im Key-Kloster und in den umliegenden Dörfern und entwickelte Konzepte für kostengünstige <strong>Smart-Microgrid-Controller</strong>.</p>
+<p>Die hier in Deutschland verfügbaren Netzsteuerboxen kosten mehrere Hundert bis Tausend Euro – keine realistische Lösung für die Bevölkerung vor Ort. Stattdessen planten wir <strong>Raspberry Pi-basierte Systeme</strong>, vernetzt über Ethernet oder lokale Mesh-Netze.</p>
+<h2 id="Forschung">Forschung</h2>
+<p><img src="/images/Key_Monastery_Spiti.png" alt="Das Stromnetz des Key-Klosters" /></p>
+<h2 id="Datenerhebung">Datenerhebung</h2>
+<p>Durch den Besuch öffentlicher Schulen im Englischunterricht konnte ich mit Jugendlichen über den Stromzustand in ihren Haushalten sprechen und umfangreiche Daten erheben. Insgesamt nahmen <strong>145 Teilnehmer aus über sechs Schulen</strong> in etwa <strong>vier Distrikten</strong> teil – alle im indischen Himalaya.</p>
+<p>Der Altersdurchschnitt lag bei 17 Jahren. Durchschnittlich leben 6 Personen pro Haushalt mit etwa 5 Smart-Geräten. Nur 2 % der Haushalte hatten gar keine, 42 % verfügten über Computer oder Laptops.</p>
<blockquote>
-<p>Average quality in summer: 7.1
-Average quality in monsoon: 5.6
-Average quality in autumn: 7.1
-Average quality in winter: 4.0</p>
+<p>Durchschnittliche Stromqualität (1 – 10):<br />
+Sommer: 7,1 Monsun: 5,6 Herbst: 7,1 Winter: 4,0</p>
</blockquote>
-<p>So, as you would expect, during winter, but also when it rains, the felt quality drops by more than 30 percent on average.
-As for the daily supply time, the average sits at 15.1 hours out of 24, meaning the people have electricity only for 62.9 percent of the time, some, as for example the people in Diskit only have a sad 4 hours of daily access. On top of that, this estimation does not account for the snowfalls in Spiti for example, where it is not uncommon to experience 3 consecutive days of powercut or more.
-As the Power Meter is supplied by the government, a solid 82 percent of the houses have a working power meter, if one assumes that the 13 percent who did not know whether they have a power meter, do have one, we can say that around 95% of the houses have a power meter.</p>
-<p>Another goal of the studies was to find out what would incline people to be caring and sharing with the available electricity, something rather unimaginable here in Germany.</p>
-<p>In general, the uninformed openness to delaying usage of electricity on a scale of 1-10 was around 5.5, with the additional information that a smart delay would cause an overall price reduction, the acceptance went up to 6.9, a good 14%. This implies that people would be a lot more inclined to give up conveniences if the benefits have a direct impact on them.</p>
+<p>Im Winter oder bei Regen sinkt die Qualität also deutlich – um über 30 %.<br />
+Im Durchschnitt haben Haushalte <strong>15,1 Stunden Strom pro Tag</strong> (≈ 63 %). Einige Regionen, wie Diskit, nur rund 4 Stunden.</p>
+<p>Etwa 95 % der Haushalte besitzen funktionierende Stromzähler.</p>
+<p>Ein weiteres Ziel war herauszufinden, <strong>was Menschen dazu bewegt, Strom zu teilen oder zu verschieben</strong>.<br />
+Ohne zusätzliche Information lag die Bereitschaft zur Verzögerung des Verbrauchs bei 5,5 / 10 – mit Aussicht auf Kostenvorteile stieg sie auf 6,9.</p>
<h2 id="Simulation">Simulation</h2>
-<p>After collecting all the estimated electric appliances of the local population, I simulated the use of 200 Solar Panels with 300Wp each, once for simultaneous electricity use, and once for mitigated electricity peaks through smart optimization and electricity usage delay.
-<img src="/images/sam_sim.png" alt="SAM Simulation of a local solar system " />
-<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimized" /></p>
-<p>Although solar is definitely not the optimal choice here and generates lots of issues with energy storage and battery charging at negative degrees, we figured that this was the way to go for the project.
-And as you can see, optimizing peak usage can improve solar from generating only one-fifth of the demand in winter to about half the demand in winter. Keeping in mind here, that the added solar farm was only intended to supply additional energy and not replace existing solutions, such a "small" farm would be a real lifesaver there and optimize the limited space in extremely mountainous terrain.</p>
-<h2 id="Closing_words">Closing words</h2>
-<p>There are to sides which the problems can be tackled: we can bring the total energy production up, by adding more panels or electricity by other means, but we can also try and bring the total demand down. This is to be achieved by investing strictly in the most energy-efficient appliances. Even replacing older, not-so-efficient appliances might sometimes be of use.
-But ensuring efficient use is not the only way to bring down the overall demand.</p>
-<p>As introduced as core ideas for the whole project, sharing and delaying will prove immensely useful. How so?
-By sharing, we mean a concept that is already widely applied in the relevant areas. What to do in a Village that has no access to water? Will we send each household out to the faraway river to catch water for their family? Or would we join hands in a community effort to dig a central well used by everyone?</p>
-<p>So, when we look at sharing electricity, how would we apply the concept? We take the appliances that consume the most energy individually and scale them up in order to increase efficiency. For example, in our case, that is most applicable to electric heating. If we manage to heat central community spaces available for everyone, naturally, fewer individual rooms will have to be heated. Similarly, one could declare a room as a public cinema, where people come together and watch Tv on a big Projector. Twice as fun, and conserving a great deal of energy again. Such ideas and others have to be realized in order to be able to match the total demand with the available supply.</p>
-<p>Sadly, the project was never taken up further, and the situation for the people in the Spiti Valley has not improved. Two years ago, a road directly through the mountains was finished, making the population hopeful for an increase in tourism, increasing the chances of the economic viability of improved solutions.
-I spent my time there in the function of a research intern, having no real say in the realization of the project. The problem remains, and I still think that decentral solutions look to be the most promising for this specific location. Of course, the Himalayas present a bit of an extreme location, but that doesn't change the fact that people live there and have a basic human right to electricity.</p>
+<p>Basierend auf den Daten simulierte ich den Einsatz von <strong>200 Solarmodulen à 300 Wp</strong>, einmal mit und einmal ohne intelligente Laststeuerung.</p>
+<p><img src="/images/sam_sim.png" alt="SAM Simulation eines lokalen Solarsystems" /><br />
+<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimiert" /></p>
+<p>Auch wenn Solar nicht optimal ist – vor allem wegen Kälte und Batterielagerung – zeigte sich, dass <strong>intelligente Lastverteilung</strong> den nutzbaren Ertrag im Winter von einem Fünftel auf etwa die Hälfte steigern kann.</p>
+<h2 id="Schlusswort">Schlusswort</h2>
+<p>Das Problem lässt sich aus zwei Richtungen angehen:</p>
+<ol>
+<li><strong>Produktion erhöhen</strong> – mehr Module, mehr Energiequellen.</li>
+<li><strong>Verbrauch senken</strong> – effizientere Geräte, gemeinschaftliche Nutzung.</li>
+</ol>
+<p>Das Konzept des <strong>Teilens und Verzögerns</strong> ist zentral. Wie bei einem gemeinschaftlich genutzten Brunnen kann auch Strom gemeinschaftlich erzeugt und genutzt werden.<br />
+Gemeinsam beheizte Räume oder öffentliche Projekträume sparen Energie und fördern Gemeinschaft.</p>
+<p>Leider wurde das Projekt nie weitergeführt, und die Situation im Spiti-Tal hat sich kaum verbessert. Eine neue Bergstraße gibt Hoffnung auf mehr Tourismus – und damit auf wirtschaftlich tragfähige Lösungen.</p>
+<p>Ich selbst war als Forschungspraktikant beteiligt, ohne Einfluss auf die Umsetzung. Dennoch bin ich überzeugt, dass <strong>dezentrale Lösungen</strong> der richtige Weg sind – gerade für extreme Regionen wie den Himalaya.<br />
+Denn eines bleibt wahr: <strong>Elektrizität ist ein Menschenrecht.</strong></p>

- <p>Being involved with 3D Printers, there is the issue of sustainability that I am confronted with regularly.
-Most 3D printed parts never get recycled and add to the global waste problem, rather than reducing it.
-The printer most certainly doesn’t care what it is printing, the main problem is the dimensional accuracy and the purity of the material. All of this leads to a huge industry, Germany being especially involved, using loads of virgin plastic.</p>

-We can design our products to last longer, we can also print recycling labels on them so they do not have to get burned after their first life. We can take care to only print functional objects, not just fun toys nobody uses.
-Yet, none of that prevents the use of virgin plastics. If you buy a spool of filament, there are some recycled options, but usually at twice the price at worse quality. No wonder recycled filament fails to convince the masses. It is mostly a fun thing YouTubers can pursue, not a valid commercial process.</p>

Identifying the exact material of a piece of trash is a very hard problem, definitely not solved yet. So why do we mix the plastic up in the first place?

-This only really works when I am thinking in a local and decentral environment.
-The existing recycling facilities clearly will not be able to provide 200 different containers for 200 different types of plastic.

-<p>This is the Filastruder, designed and made by Tim Elmore, in an attempt to create the cheapest viable way to extrude plastic. The biggest cost issue is the tight industrial tolerances in thickness that have to be adhered to. This is in essence what separates good from the bad filament. The industry standard nowadays is at +-0.03mm. Hard to achieve on a DIY setup, but not unheard of. The setup, like any bigger industry equivalent, consists of a motor pressing plastic pellets through a heated screw, extruding molten plastic at the end through a nozzle, and setting the diameter. The leftmost machine is responsible for winding the filament properly onto a spool.</p>
-<p>Here you can see the extrusion process in action.</p>

-<p>The Filastruder is controlled by an Arduino and is highly configurable. The laser sensor visible in the video is already working, but I am missing more direct control over the diameter of the filament.</p>
-<p>When it all really comes down to the single variable of the filament diameter responsible for the quality of my recycled project, a simple Machine Learning optimization directly jumps at me: I have a few variables like winder speed, extrusion speed, heat, and cooling intensity. These variables can be optimized on the fly for an exact diameter. This is actually roughly how virgin filament is produced, commercial facilities just manage much faster.</p>
-<p><img src="/assets/images/recycling_variables.png" alt="The variables in an iterative optimization" /></p>
-<p>So far, I am aware of a few companies and academic projects attempting this process, but none of them manage to get either the quality or the price of other products available. Automatization does not just take out jobs away, I think it can also be a helpful tool, for example tackling environmental issues such as this one.</p>
-<p>This project is very dear to my heart and I plan to investigate it further in the form of a master thesis.
-The realization will require many skills I am already picking up or still need to work on within the Design and Computation program.

- <h2 id="2020:_discovering_jekyll">2020: discovering jekyll</h2>
-<p>For applying to my master's program in 2020, a portfolio was required, and since it was more or less for a design program, I wanted to have a nice website.
-After trying for a month to get what I wanted out of WordPress, and angrily quitting multiple times, I discovered <a href="https://jekyllrb.com">Jekyll</a>.
-Back then, <a href="https://gohugo.io">Hugo</a> and <a href="https://www.11ty.dev">11ty</a> were the newer kids on the block, but I was heavily relying on the free hosting from <a href="https://pages.github.com">GitHub Pages</a>, where Jekyll was the easiest to integrate.</p>
-<p>Back then, looking for inspiration, I had an ethics professor I really liked, and he had a Jekyll site with the <a href="https://mmistakes.github.io/minimal-mistakes/">Minimal Mistakes</a> theme.
-<a href="https://rainermuehlhoff.de">Prof. Mühlhoff</a></p>
-<p>I went about using Minimal Mistakes, and it was a great experience.
-The resulting portfolio at least got me into the master's, and I fell in love with the general idea of being able to write sites in markdown, while a program would take care of the rest.</p>
-<p>For years, Jekyll was my go-to for building static websites.
-It was familiar, widely supported, and part of the broader Ruby ecosystem.
-But over time, my frustrations grew—slow builds, complicated plugin setups, and a dependency stack that never felt quite right.
-To be honest, many of the drawbacks were totally not Jekyll’s fault. It was just slow, otherwise fine. But especially using GitHub Pages imposed quite a few limitations on plugins and themes.
-Also, maybe I didn’t put in enough effort, but I could never really get theme modifications working. Just extending the theme to show multiple authors was a pain—although it was eventually working.</p>
-<p>On now finishing the master's, I wanted a visual overhaul, and while browsing for inspiration again, using Jekyll at all got questioned again.
-I knew I wanted a static site generator, because markdown is the shit.
-So after looking around further, <strong><a href="https://www.getzola.org/">Zola</a></strong> emerged—actually through a chatbot suggestion 😄</p>
-<p>Recently, I made the leap to Zola, a Rust-powered static site generator, and I don't see myself going back.</p>
-<hr />
-<h2 id="rust_feels_right">rust feels right</h2>
-<p>I’ve always admired <a href="https://www.rust-lang.org/">Rust</a> for its speed, safety, and modern tooling.
-Using a static site generator built with Rust just made sense. <strong>Zola is fast</strong>—blazing fast.
-Even during local development, rebuilds are near-instant, and that alone makes the writing process smoother and more enjoyable.</p>
-<p>Plus, using something written in Rust means fewer external dependencies, no bundler hell, and zero Ruby setup headaches.
-I can just download the binary, run it, and get going. It respects my time.</p>
-<hr />
-<h2 id="zola_is_thoughtfully_designed">zola is thoughtfully designed</h2>
-<p>Beyond performance, Zola is just really well designed.
-Its template syntax (thanks to <a href="https://tera.netlify.app">Tera</a>) is more powerful and readable than Liquid.
-The built-in shortcodes, pagination, and asset pipelines all feel cohesive and purposeful.
-There’s very little “configuration over convention” fatigue that Jekyll often gave me.</p>
-<p>And even though both systems are markdown-based, migrating wasn’t just a matter of copy-pasting files.
-I had to rethink frontmatter, adjust templates, and wrangle image paths and shortcodes.
-The structure and behavior are different enough that it felt like a real rebuild—not just a port.</p>
-<hr />
-<h2 id="duckquill_made_me_switch">duckquill made me switch</h2>
-<p>The real catalyst, though? <a href="https://github.com/daudix/duckquill"><strong>Duckquill</strong></a>, a stunning Zola theme built by <a href="https://github.com/daudix">Daudix</a>.
-It struck the perfect balance between minimalism and elegance—exactly the aesthetic I wanted but could never quite achieve with Jekyll.
-Duckquill didn’t just make Zola usable for me; it made it <em>irresistible</em>.</p>
-<p>What really sets <strong>Duckquill</strong> apart—beyond its clean typography and smart layout—is how well it supports a vision of digital autonomy.
-The theme comes with <strong>Mastodon-powered comments</strong>, allowing for lightweight, federated interaction without relying on big centralized platforms.
-This fits perfectly with my goal of reclaiming control through <strong>self-hosting</strong>.
-Whether it's running my own site, owning my content, or interacting through the fediverse, Duckquill reinforces those values rather than working against them.
-It’s a rare example of design and infrastructure aligning with personal principles.</p>
-<hr />
-<h2 id="final_thoughts">final thoughts</h2>
-<p>Switching from Jekyll to Zola wasn’t effortless, but it was absolutely worth it.
-I now have a faster, more reliable, and better-looking site that’s easier to maintain and feels like it fits my tooling philosophy.</p>
-<p>If you're feeling the weight of your current setup, maybe it's time to try Zola—and give Duckquill a spin while you're at it.</p>

-<p>Starting out, I found it fascinating, how just 4 rather simple ingredients, malt, hops, water and yeast, can form such an incredible range of taste experiences.

-<p>Why do I present such an unrelated non-academic hobby here? I simply do not regard it as unrelated, experimenting and optimizing a process and a workflow, creating optimal conditions for the yeast to do its job feels very similar to approaching a coding project.
-Yeast and what it does fascinates me. Every time I open the latch to release some pressure on the Tank I think of the awesome symbiotic relationships yeast has with humans and how many different strains live there together to create a unique, yet tailored flavor. Several ideas are floating around of changing the brewing process by capturing the created carbon dioxide and using it productively. I could see a car tire being filled with my beer gas, or an algae farm munching away on my CO2 byproducts. Within a closed-loop pressurized system, such ideas actually become realizable and I would love to explore them further.</p>

- <p>Being involved with 3D Printers, there is the issue of sustainability that I am confronted with regularly.
-Most 3D printed parts never get recycled and add to the global waste problem, rather than reducing it.
-The printer most certainly doesn’t care what it is printing, the main problem is the dimensional accuracy and the purity of the material. All of this leads to a huge industry, Germany being especially involved, using loads of virgin plastic.</p>
-<p>What can be done about it?
-We can design our products to last longer, we can also print recycling labels on them so they do not have to get burned after their first life. We can take care to only print functional objects, not just fun toys nobody uses.
-Yet, none of that prevents the use of virgin plastics. If you buy a spool of filament, there are some recycled options, but usually at twice the price at worse quality. No wonder recycled filament fails to convince the masses. It is mostly a fun thing YouTubers can pursue, not a valid commercial process.</p>

-<p>When it all really comes down to the single variable of the filament diameter responsible for the quality of my recycled project, a simple Machine Learning optimization directly jumps at me: I have a few variables like winder speed, extrusion speed, heat, and cooling intensity.

-<p>This project is very dear to my heart and I plan to investigate it further in the form of a master thesis.

-<p>This project is very dear to my heart and I plan to investigate it further in the form of a master thesis.
-The realization will require many skills I am already picking up or still need to work on within the Design and Computation program.

+<p>Beim Erlernen des 3D-Drucks hat mich vor allem die Möglichkeit fasziniert, bestehende Produkte zu verändern oder zu reparieren.<br />
+Auch wenn es eine großartige Community mit vielen guten und kostenlosen Modellen gibt, bin ich schnell an den Punkt gekommen, an dem ich nicht fand, was ich suchte.<br />
+Mir wurde klar, dass dies eine wesentliche Fähigkeit ist, um nicht nur 3D-Drucker, sondern grundsätzlich jede Art von Produktionsmaschine sinnvoll zu nutzen.</p>
+<p>Da ich alles über 3D-Druck auf YouTube gelernt habe und dort fast alle mit <strong>Fusion 360</strong> arbeiteten, habe ich mich ebenfalls dafür entschieden.<br />
+Rückblickend war das eine sehr gute Wahl – ich habe mich in die Möglichkeiten des <strong>parametrischen Designs</strong> verliebt.<br />
+Unten findest du einige meiner Entwürfe.<br />
+Der Prozess selbst macht mir unglaublich viel Spaß und ich möchte ihn noch weiter vertiefen.</p>
+<p>Durch Ausprobieren habe ich bereits viel darüber gelernt, wie man speziell für den 3D-Druck konstruiert.<br />
+Trotzdem habe ich oft das Gefühl, dass mir ein tieferes Verständnis für <strong>ästhetische Gestaltung</strong> fehlt.<br />
+Ich möchte meine generelle Fähigkeit erweitern, physische Objekte zu entwerfen – etwas, das ich mir im Masterstudium erhoffe.</p>

-<p>Besides coming up with new objects, incorporating the real world is also an interest of mine.</p>
-<h3 id="Interaction_with_real_objects_and_environments">Interaction with real objects and environments</h3>
-<p>In the last few years I have played around with a few smartphone cameras and was always quite sad, that my scans were never quite accurate enough to do cool stuff with them.
-I could not really afford real 3D scanner and had already started cobbling together a raspberry Pi camera with a cheap TOF sensor, which is a simple, but not quite as good replacement for a laser or a lidar sensor, but then Apple came out with the first phones with accessible Lidar sensor.
-Recently, through work at the university I got access to a device with a lidar sensor and started having fun with it.
-See some examples here:</p>

-<p>This last one was scanned with just my smartphone camera. You can see that the quality is notably worse, but considering is was created with just a single, run-of-the-mill smartphone sensor, I think it is still pretty impressive and will certainly do something towards democratizing such technologies and abilities.</p>

+<p>Neben dem Entwerfen neuer Objekte interessiert mich auch die Integration der <strong>realen Welt</strong> in meine Arbeit.</p>
+<h3 id="Interaktion_mit_realen_Objekten_und_Umgebungen">Interaktion mit realen Objekten und Umgebungen</h3>
+<p>In den letzten Jahren habe ich mit verschiedenen Smartphone-Kameras experimentiert – leider waren meine Scans meist nicht präzise genug, um wirklich etwas damit anzufangen.<br />
+Ein professioneller 3D-Scanner war zu teuer, also bastelte ich mir eine Kombination aus einer <strong>Raspberry-Pi-Kamera</strong> und einem günstigen <strong>TOF-Sensor</strong>.<br />
+Das Setup ist simpel, aber bei weitem nicht so genau wie Laser- oder LiDAR-Sensoren. Dann brachte Apple die ersten Geräte mit <strong>zugänglichem LiDAR</strong> heraus.</p>
+<p>Durch meine Arbeit an der Universität hatte ich schließlich Zugriff auf ein Gerät mit LiDAR und begann, damit zu experimentieren.<br />
+Ein paar Beispiele siehst du hier:</p>
+<div class="sketchfab-embed-wrapper"> <iframe title="DigiLab Hauptraum" frameborder="0" allowfullscreen mozallowfullscreen="true" webkitallowfullscreen="true" allow="autoplay; fullscreen; xr-spatial-tracking" xr-spatial-tracking execution-while-out-of-viewport execution-while-not-rendered web-share width="800" height="600" src="https://sketchfab.com/models/c880892c6b4746bc80717be1f81bf169/embed?ui_theme=dark&dnt=1"> </iframe> </div>

+<p>Der letzte Scan hier wurde nur mit einer <strong>Smartphone-Kamera</strong> erstellt.<br />
+Man erkennt deutlich, dass die Qualität geringer ist, aber angesichts der einfachen Technik finde ich das Ergebnis beeindruckend –<br />
+und es zeigt, wie sehr solche Technologien gerade <strong>demokratisiert</strong> werden.</p>

-<h2 id="Perspective">Perspective</h2>
-<p>What this section is supposed to deliver is the message that I am currently not where I want to be navigating the vast possibilities of CAD. I feel confident enough to approach small repairs around the flat with a new perspective, but I still lack technical expertise when approaching a collection composite parts, having to function together. I still have lots of projects halfdone or half-thought and one major reason is that there is no real critical exchange within my field of study.</p>
-<p>I want more than designing figurines or wearables.
-I want to incorporate 3D printing as a method to extend the abilities of other tools, have mechanical and electrical purposes, be foodsafe and engaging.
-I fell in love with the idea of designing a toy system, inspired by <a href="https://www.kickstarter.com/projects/makeway/makeway-create-intricate-courses-watch-your-marbles-soar">Makeways on Kickstarter</a>, I have already started adding my own parts to their set.</p>
-<p>I dream of my very own 3D printed coffeecup, one that is both foodsafe and dishwasher-surviving. For that, I would have to do quite a bit of material research, but that just makes the idea so much more appealing.
-I would love finding a material composition incorporating waste to stop relying on plastics, or at least on fossile plastics.
-Once in Berlin, I would want to talk to the people at <a href="https://www.kaffeeform.com/en/">Kaffeform</a> producing largely compostable Coffee Cups incorporating a significant amount of old ground espresso, albeit using injection molding for their process.
-The industry selling composite filaments is much more conservative with the percentage of non-plastic additives, because with a nozzle extrusion process there is much more to go wrong.
-Still, I would love to explore that avenue further and think there is a lot to be gained from looking at pellet printers.</p>
-<p>I also credit huge parts of my exploration process into local recycling to the awesome people at <a href="https://preciousplastic.com">Precious Plastic</a>, who I will join over the summer to learn more about their system.</p>
-<p>I find it hard to write anything about CAD without connecting it directly to a manufacturing process.
-And I believe that's a good thing. Always tying a design process to its realization, grounds the process and attaches to it some immediacy.</p>
-<p>For me to become more confident in this process, I am still missing more expertise in organic shapes, so I would be happy to dig more into Blender, an awesome tool that in my mind is far too powerful to dive into it with just youtube lessons.</p>

+<h2 id="Perspektive">Perspektive</h2>
+<p>Was dieser Abschnitt zeigen soll: Ich bin beim Thema <strong>CAD</strong> noch nicht da, wo ich gerne wäre.<br />
+Ich fühle mich sicher genug, um kleine Reparaturen im Alltag anzugehen,<br />
+aber beim <strong>Konstruieren komplexer Bauteilgruppen</strong>, die zusammen funktionieren müssen, fehlt mir noch technisches Know-how.<br />
+Viele meiner Projekte sind halbfertig – einer der Hauptgründe ist der <strong>Mangel an fachlichem Austausch</strong> in meinem Umfeld.</p>
+<p>Ich möchte mehr als nur Figuren oder Wearables gestalten.<br />
+Ich möchte den <strong>3D-Druck als Werkzeugerweiterung</strong> nutzen –<br />
+für mechanische oder elektrische Anwendungen, lebensmittelechte Objekte, oder einfach Dinge, die begeistern.<br />
+Ich liebe die Idee, ein <strong>Baukastensystem</strong> zu entwickeln.<br />
+Inspiriert von <a href="https://www.kickstarter.com/projects/makeway/makeway-create-intricate-courses-watch-your-marbles-soar">Makeways auf Kickstarter</a> habe ich bereits angefangen, eigene Teile zu entwerfen.</p>
+<p>Ein Traum von mir ist eine <strong>eigene 3D-gedruckte Kaffeetasse</strong>, die sowohl <strong>spülmaschinenfest als auch lebensmittelecht</strong> ist.<br />
+Dafür müsste ich viel Materialforschung betreiben – aber genau das macht es spannend.<br />
+Ich möchte ein Material finden, das <strong>Abfälle</strong> einbezieht, um weniger von <strong>fossilen Kunststoffen</strong> abhängig zu sein.<br />
+In Berlin möchte ich mich mit den Leuten von <a href="https://www.kaffeeform.com/de/">Kaffeform</a> austauschen, die <strong>kompostierbare Becher</strong> aus gebrauchten Espressoresten herstellen (wenn auch per Spritzgussverfahren).</p>
+<p>Die Hersteller von <strong>Komposit-Filamenten</strong> sind bei der Beimischung nicht-plastischer Stoffe sehr vorsichtig,<br />
+weil der <strong>Extrusionsprozess</strong> durch Düsen leicht fehleranfällig ist.<br />
+Trotzdem glaube ich, dass gerade in diesem Bereich noch viel Potenzial steckt – besonders mit <strong>Pelletdruckern</strong>.</p>
+<p>Große Teile meiner Auseinandersetzung mit <strong>lokalem Recycling</strong> verdanke ich den großartigen Leuten von <a href="https://preciousplastic.com">Precious Plastic</a>, deren Open-Source-Designs mich sehr inspiriert haben.<br />
+Ich finde es schwer, über CAD zu schreiben, ohne gleichzeitig über den <strong>Herstellungsprozess</strong> zu sprechen –<br />
+und ich halte das für etwas Gutes.<br />
+Design und Umsetzung gehören für mich zusammen.</p>
+<p>Um noch sicherer zu werden, möchte ich mich stärker auf <strong>organische Formen</strong> konzentrieren.<br />
+Deshalb will ich tiefer in <strong>Blender</strong> einsteigen – ein großartiges Tool, das viel zu mächtig ist, um es nur über YouTube zu lernen.</p>

+<p>Beim Erlernen des 3D-Drucks hat mich vor allem die Möglichkeit fasziniert, bestehende Produkte zu verändern oder zu reparieren.<br />
+Auch wenn es eine großartige Community mit vielen guten und kostenlosen Modellen gibt, bin ich schnell an den Punkt gekommen, an dem ich nicht fand, was ich suchte.<br />
+Mir wurde klar, dass dies eine wesentliche Fähigkeit ist, um nicht nur 3D-Drucker, sondern grundsätzlich jede Art von Produktionsmaschine sinnvoll zu nutzen.</p>
+<p>Da ich alles über 3D-Druck auf YouTube gelernt habe und dort fast alle mit <strong>Fusion 360</strong> arbeiteten, habe ich mich ebenfalls dafür entschieden.<br />
+Rückblickend war das eine sehr gute Wahl – ich habe mich in die Möglichkeiten des <strong>parametrischen Designs</strong> verliebt.<br />
+Unten findest du einige meiner Entwürfe.<br />
+Der Prozess selbst macht mir unglaublich viel Spaß und ich möchte ihn noch weiter vertiefen.</p>
+<p>Durch Ausprobieren habe ich bereits viel darüber gelernt, wie man speziell für den 3D-Druck konstruiert.<br />
+Trotzdem habe ich oft das Gefühl, dass mir ein tieferes Verständnis für <strong>ästhetische Gestaltung</strong> fehlt.<br />
+Ich möchte meine generelle Fähigkeit erweitern, physische Objekte zu entwerfen – etwas, das ich mir im Masterstudium erhoffe.</p>

-<p>Besides coming up with new objects, incorporating the real world is also an interest of mine.</p>
-<h3 id="Interaction_with_real_objects_and_environments">Interaction with real objects and environments</h3>
-<p>In the last few years I have played around with a few smartphone cameras and was always quite sad, that my scans were never quite accurate enough to do cool stuff with them.
-I could not really afford real 3D scanner and had already started cobbling together a raspberry Pi camera with a cheap TOF sensor, which is a simple, but not quite as good replacement for a laser or a lidar sensor, but then Apple came out with the first phones with accessible Lidar sensor.
-Recently, through work at the university I got access to a device with a lidar sensor and started having fun with it.
-See some examples here:</p>

-<p>This last one was scanned with just my smartphone camera. You can see that the quality is notably worse, but considering is was created with just a single, run-of-the-mill smartphone sensor, I think it is still pretty impressive and will certainly do something towards democratizing such technologies and abilities.</p>

+<p>Neben dem Entwerfen neuer Objekte interessiert mich auch die Integration der <strong>realen Welt</strong> in meine Arbeit.</p>
+<h3 id="Interaktion_mit_realen_Objekten_und_Umgebungen">Interaktion mit realen Objekten und Umgebungen</h3>
+<p>In den letzten Jahren habe ich mit verschiedenen Smartphone-Kameras experimentiert – leider waren meine Scans meist nicht präzise genug, um wirklich etwas damit anzufangen.<br />
+Ein professioneller 3D-Scanner war zu teuer, also bastelte ich mir eine Kombination aus einer <strong>Raspberry-Pi-Kamera</strong> und einem günstigen <strong>TOF-Sensor</strong>.<br />
+Das Setup ist simpel, aber bei weitem nicht so genau wie Laser- oder LiDAR-Sensoren. Dann brachte Apple die ersten Geräte mit <strong>zugänglichem LiDAR</strong> heraus.</p>
+<p>Durch meine Arbeit an der Universität hatte ich schließlich Zugriff auf ein Gerät mit LiDAR und begann, damit zu experimentieren.<br />
+Ein paar Beispiele siehst du hier:</p>

+<p>Der letzte Scan hier wurde nur mit einer <strong>Smartphone-Kamera</strong> erstellt.<br />
+Man erkennt deutlich, dass die Qualität geringer ist, aber angesichts der einfachen Technik finde ich das Ergebnis beeindruckend –<br />
+und es zeigt, wie sehr solche Technologien gerade <strong>demokratisiert</strong> werden.</p>

-<h2 id="Perspective">Perspective</h2>
-<p>What this section is supposed to deliver is the message that I am currently not where I want to be navigating the vast possibilities of CAD. I feel confident enough to approach small repairs around the flat with a new perspective, but I still lack technical expertise when approaching a collection composite parts, having to function together. I still have lots of projects halfdone or half-thought and one major reason is that there is no real critical exchange within my field of study.</p>
-<p>I want more than designing figurines or wearables.
-I want to incorporate 3D printing as a method to extend the abilities of other tools, have mechanical and electrical purposes, be foodsafe and engaging.
-I fell in love with the idea of designing a toy system, inspired by <a href="https://www.kickstarter.com/projects/makeway/makeway-create-intricate-courses-watch-your-marbles-soar">Makeways on Kickstarter</a>, I have already started adding my own parts to their set.</p>
-<p>I dream of my very own 3D printed coffeecup, one that is both foodsafe and dishwasher-surviving. For that, I would have to do quite a bit of material research, but that just makes the idea so much more appealing.
-I would love finding a material composition incorporating waste to stop relying on plastics, or at least on fossile plastics.
-Once in Berlin, I would want to talk to the people at <a href="https://www.kaffeeform.com/en/">Kaffeform</a> producing largely compostable Coffee Cups incorporating a significant amount of old ground espresso, albeit using injection molding for their process.
-The industry selling composite filaments is much more conservative with the percentage of non-plastic additives, because with a nozzle extrusion process there is much more to go wrong.
-Still, I would love to explore that avenue further and think there is a lot to be gained from looking at pellet printers.</p>
-<p>I also credit huge parts of my exploration process into local recycling to the awesome people at <a href="https://preciousplastic.com">Precious Plastic</a>, who I will join over the summer to learn more about their system.</p>
-<p>I find it hard to write anything about CAD without connecting it directly to a manufacturing process.
-And I believe that's a good thing. Always tying a design process to its realization, grounds the process and attaches to it some immediacy.</p>
-<p>For me to become more confident in this process, I am still missing more expertise in organic shapes, so I would be happy to dig more into Blender, an awesome tool that in my mind is far too powerful to dive into it with just youtube lessons.</p>

+<p>Was dieser Abschnitt zeigen soll: Ich bin beim Thema <strong>CAD</strong> noch nicht da, wo ich gerne wäre.<br />
+Ich fühle mich sicher genug, um kleine Reparaturen im Alltag anzugehen,<br />
+aber beim <strong>Konstruieren komplexer Bauteilgruppen</strong>, die zusammen funktionieren müssen, fehlt mir noch technisches Know-how.<br />
+Viele meiner Projekte sind halbfertig – einer der Hauptgründe ist der <strong>Mangel an fachlichem Austausch</strong> in meinem Umfeld.</p>
+<p>Ich möchte mehr als nur Figuren oder Wearables gestalten.<br />
+Ich möchte den <strong>3D-Druck als Werkzeugerweiterung</strong> nutzen –<br />
+für mechanische oder elektrische Anwendungen, lebensmittelechte Objekte, oder einfach Dinge, die begeistern.<br />
+Ich liebe die Idee, ein <strong>Baukastensystem</strong> zu entwickeln.<br />
+Inspiriert von <a href="https://www.kickstarter.com/projects/makeway/makeway-create-intricate-courses-watch-your-marbles-soar">Makeways auf Kickstarter</a> habe ich bereits angefangen, eigene Teile zu entwerfen.</p>
+<p>Ein Traum von mir ist eine <strong>eigene 3D-gedruckte Kaffeetasse</strong>, die sowohl <strong>spülmaschinenfest als auch lebensmittelecht</strong> ist.<br />
+Dafür müsste ich viel Materialforschung betreiben – aber genau das macht es spannend.<br />
+Ich möchte ein Material finden, das <strong>Abfälle</strong> einbezieht, um weniger von <strong>fossilen Kunststoffen</strong> abhängig zu sein.<br />
+In Berlin möchte ich mich mit den Leuten von <a href="https://www.kaffeeform.com/de/">Kaffeform</a> austauschen, die <strong>kompostierbare Becher</strong> aus gebrauchten Espressoresten herstellen (wenn auch per Spritzgussverfahren).</p>
+<p>Die Hersteller von <strong>Komposit-Filamenten</strong> sind bei der Beimischung nicht-plastischer Stoffe sehr vorsichtig,<br />
+weil der <strong>Extrusionsprozess</strong> durch Düsen leicht fehleranfällig ist.<br />
+Trotzdem glaube ich, dass gerade in diesem Bereich noch viel Potenzial steckt – besonders mit <strong>Pelletdruckern</strong>.</p>
+<p>Große Teile meiner Auseinandersetzung mit <strong>lokalem Recycling</strong> verdanke ich den großartigen Leuten von <a href="https://preciousplastic.com">Precious Plastic</a>, deren Open-Source-Designs mich sehr inspiriert haben.<br />
+Ich finde es schwer, über CAD zu schreiben, ohne gleichzeitig über den <strong>Herstellungsprozess</strong> zu sprechen –<br />
+und ich halte das für etwas Gutes.<br />
+Design und Umsetzung gehören für mich zusammen.</p>
+<p>Um noch sicherer zu werden, möchte ich mich stärker auf <strong>organische Formen</strong> konzentrieren.<br />
+Deshalb will ich tiefer in <strong>Blender</strong> einsteigen – ein großartiges Tool, das viel zu mächtig ist, um es nur über YouTube zu lernen.</p>

-<p>Implemented in Unity, Ballpark is a Concept work for a collaborative 2-Player Game, where one player is a navigator with a third-person perspective and another player is a copilot, responsible for interaction with the environment – featuring mostly working physics, intelligent enemies, a gun, a grappling hook system for traversing the map, a 2D Interface for navigation and a health bar system. On top of the meanest cyberpunk vibes my past self was able to conjure.</p>

-<p>As you can see, the design faces some questionable choices, but all mechanics are homemade from the ground up and I learned a lot. I often struggle to enjoy competitive games and think there is potential in a co-dependent game interface. During early testing, we often found that it enforces player communication since already the tutorial is quite hard to beat.
-Due to me being a leftie, perhaps not entirely smart, I gave player one the keyboard arrows to work with and player two the WASD keys and left and right mouse buttons for grappling and shooting. For the game, it has an interesting side effect, in that players are forced not only to interact through the differing information on each player's screen but also have to physically interact and coordinate the controls.</p>
-<p>As you can perhaps see, the ball-rolling navigation is quite hard to use.
-It is a purely physics-based system, where, depending on the materiality of the ball, its weight, and therefore its inertia will drastically change.</p>
-<p>On small screens, the prototype version of the game is virtually impossible to control and several visual bugs within the viewport still obfuscate items when they are too close. Considering that virtually all the mechanics are written from scratch, with a follow-me camera, collision detection, smart moving agents, and a still very wonky-looking grappling gun, I still think it deserves a spot in this portfolio.
-For this project I focused completely on the mechanics of the game, resulting in lots of used prefabs and readymade 3D Objects. Next time, I want to do that myself too.</p>
-<p>I enjoyed my stint into Unity a lot and am looking forward to creating my first VR application and would love to try out some form of mechanics where the user vision is completely obfuscated by VR and they have to carry their eyes as a handheld connected camera so that the players can move around the camera itself with their hands.</p>
+<p>Das Design enthält einige fragwürdige Entscheidungen, aber alle Mechaniken sind <strong>von Grund auf selbst entwickelt</strong>, und ich habe viel dabei gelernt. Ich spiele selten kompetitive Spiele, sehe aber Potenzial in einer <strong>kooperativen, voneinander abhängigen Spielmechanik</strong>. Schon das Tutorial erfordert intensive Spielerkommunikation.</p>
+<p>Als Linkshänder habe ich Spieler eins die Pfeiltasten gegeben und Spieler zwei die WASD-Tasten sowie die linken und rechten Maustasten für Schießen und Greifhaken. Das führt zu einem interessanten Nebeneffekt: Spieler müssen nicht nur über unterschiedliche Informationen auf ihren Bildschirmen kommunizieren, sondern auch ihre Steuerung physisch koordinieren.</p>
+<p>Die <strong>Ball-Navigation</strong> ist ziemlich schwer zu kontrollieren.<br />
+Es handelt sich um ein <strong>rein physikbasiertes System</strong>, bei dem Material, Gewicht und Trägheit der Kugel die Bewegung stark beeinflussen.</p>
+<p>Auf kleinen Bildschirmen ist die Steuerung praktisch unmöglich, und einige visuelle Bugs verdecken Objekte bei zu naher Ansicht. Dennoch, da fast alle Mechaniken von Grund auf programmiert wurden – inklusive Follow-Camera, Kollisionsabfrage, smarten Agenten und einem noch etwas wackeligen Greifhaken – verdient das Projekt einen Platz im Portfolio.</p>
+<p>Für dieses Projekt habe ich mich komplett auf <strong>Mechaniken</strong> konzentriert, weshalb viele fertige Prefabs und 3D-Objekte verwendet wurden. Beim nächsten Mal möchte ich diese auch selbst erstellen.</p>
+<p>Ich habe Unity sehr genossen und freue mich darauf, meine erste <strong>VR-Anwendung</strong> zu entwickeln.<br />
+Ich möchte Mechaniken ausprobieren, bei denen die Sicht des Spielers durch VR komplett blockiert wird und die Augen als <strong>tragbare, verbundene Kamera</strong> bewegt werden, sodass die Spieler die Kamera selbst physisch steuern können.</p>

-<p>In an environment reliant on hydro-energy and solar (diesel transport is unreliable due to snowed-in mountain roads), over 6 months of snowy winter, frequent snowstorms, and temperatures of up to -35°C, securing the grid is hard.</p>
-<p>Our way to tackle the issue was to reject the in the western society very established notion of electricity as a homogenous product with centralized production and instead researched the possibilities of a predictive, self-correcting, and decentral grid.</p>
-<p>By prioritizing energy usage cases, instead of a full blackout during a storm, essential functions like radio towers and hospitals could be partially powered and maybe stay functioning. The binarity of either having electricity or not would be replaced by assigned quantities and timeslots, in a collective effort to be mindful and distribute the electricity necessity-based.
-The ultimate vision was a live predictive electricity market, where people could even earn money by selling their allotted, but not needed electricity.
-To gauge feasibility, I conducted several psychological acceptance studies and collected data on local electricity demands.
-I simulated a typical day of electricity demand in the Key monastery and the surrounding villages and mapped out the potential to install cost-efficient smart microgrid controllers enabling such an accurate and predictive behavior.
-The smart grid operator boxes available here in Germany cost several hundred, with installation several thousand Euros, not a feasible solution for the Indian population. Instead, we wanted to use Raspberry Pi's, which are interconnected through ethernet cables or local mesh networking.</p>

-<h2 id="Data_Collection">Data Collection</h2>
-<p>Building a questionnaire and visiting public schools during their English Classes, I had the chance to speak to a range of teenagers, answering questions about the state of electricity in their homes, generating more data than I could have accomplished running from door to door without any skills speaking local dialects. The questionnaire was as scientific as I could make it in such a situation and geared towards finding the type and number of electric devices in the homes and estimating typical usage scenarios.</p>
-<p>With a total of 145 participants from more than 6 different schools and roughly 4 different districts, all located in the Indian part of the Himalayas, the findings are as follows:</p>
-<p>The participants range from 11 to 53 years, with an average of 17 years.
-The average household has 6 members with an average of 5 smart devices. Only 2 percent of the Households had not a single smart device, but at the same time, only 42 percent had direct or indirect access to a laptop or computer. So the main body of smart devices consists of smartphones with a negligible portion of tablets.
-The average total amount of electrical devices is around 11 electrical appliances per house.</p>
-<p><strong>Subjective</strong> Quality Rating on a scale of 1 to 10:</p>
+<p>Das ist <strong>Tashi Gang</strong>, ein Dorf nahe des Klosters. Es beherbergt rund 50 Menschen und ist nur drei bis vier Monate im Sommer über eine Straße erreichbar. Den Rest des Jahres sind die Bewohner auf Hubschrauber-Erste-Hilfe angewiesen – erreichbar nur über einen funktionierenden Mobilfunkturm.</p>

+<h2 id="Das_Projekt">Das Projekt</h2>
+<p>In einer Umgebung, die auf Wasser- und Sonnenenergie angewiesen ist, mit über sechs Monaten Schnee, häufigen Schneestürmen und Temperaturen bis zu –35 °C, ist die Netzsicherung schwierig.</p>
+<p>Unser Ansatz war es, die im Westen etablierte Vorstellung von Elektrizität als homogenes, zentral erzeugtes Produkt zu hinterfragen und stattdessen die Möglichkeiten eines <strong>prädiktiven, sich selbst korrigierenden und dezentralen Netzes</strong> zu erforschen.</p>
+<p>Anstatt bei einem Sturm einen kompletten Blackout zu riskieren, könnten bei einer Priorisierung der Energieverwendung wichtige Funktionen – etwa Radiotürme oder Krankenhäuser – teilweise weiterbetrieben werden. Die Binarität von Strom / kein Strom würde durch ein System von <strong>Zuteilungen nach Bedarf und Zeitfenstern</strong> ersetzt.<br />
+Langfristig war die Vision ein <strong>lokaler, prädiktiver Strommarkt</strong>, bei dem Menschen überschüssige Energie verkaufen können.</p>
+<p>Zur Machbarkeitsprüfung führte ich psychologische Akzeptanzstudien durch und sammelte Daten zum lokalen Stromverbrauch. Anschließend simulierte ich einen typischen Strombedarfstag im Key-Kloster und in den umliegenden Dörfern und entwickelte Konzepte für kostengünstige <strong>Smart-Microgrid-Controller</strong>.</p>
+<p>Die hier in Deutschland verfügbaren Netzsteuerboxen kosten mehrere Hundert bis Tausend Euro – keine realistische Lösung für die Bevölkerung vor Ort. Stattdessen planten wir <strong>Raspberry Pi-basierte Systeme</strong>, vernetzt über Ethernet oder lokale Mesh-Netze.</p>
+<h2 id="Forschung">Forschung</h2>
+<p><img src="/images/Key_Monastery_Spiti.png" alt="Das Stromnetz des Key-Klosters" /></p>
+<h2 id="Datenerhebung">Datenerhebung</h2>
+<p>Durch den Besuch öffentlicher Schulen im Englischunterricht konnte ich mit Jugendlichen über den Stromzustand in ihren Haushalten sprechen und umfangreiche Daten erheben. Insgesamt nahmen <strong>145 Teilnehmer aus über sechs Schulen</strong> in etwa <strong>vier Distrikten</strong> teil – alle im indischen Himalaya.</p>
+<p>Der Altersdurchschnitt lag bei 17 Jahren. Durchschnittlich leben 6 Personen pro Haushalt mit etwa 5 Smart-Geräten. Nur 2 % der Haushalte hatten gar keine, 42 % verfügten über Computer oder Laptops.</p>
<blockquote>
-<p>Average quality in summer: 7.1
-Average quality in monsoon: 5.6
-Average quality in autumn: 7.1
-Average quality in winter: 4.0</p>
+<p>Durchschnittliche Stromqualität (1 – 10):<br />
+Sommer: 7,1 Monsun: 5,6 Herbst: 7,1 Winter: 4,0</p>
</blockquote>
-<p>So, as you would expect, during winter, but also when it rains, the felt quality drops by more than 30 percent on average.
-As for the daily supply time, the average sits at 15.1 hours out of 24, meaning the people have electricity only for 62.9 percent of the time, some, as for example the people in Diskit only have a sad 4 hours of daily access. On top of that, this estimation does not account for the snowfalls in Spiti for example, where it is not uncommon to experience 3 consecutive days of powercut or more.
-As the Power Meter is supplied by the government, a solid 82 percent of the houses have a working power meter, if one assumes that the 13 percent who did not know whether they have a power meter, do have one, we can say that around 95% of the houses have a power meter.</p>
-<p>Another goal of the studies was to find out what would incline people to be caring and sharing with the available electricity, something rather unimaginable here in Germany.</p>
-<p>In general, the uninformed openness to delaying usage of electricity on a scale of 1-10 was around 5.5, with the additional information that a smart delay would cause an overall price reduction, the acceptance went up to 6.9, a good 14%. This implies that people would be a lot more inclined to give up conveniences if the benefits have a direct impact on them.</p>
+<p>Im Winter oder bei Regen sinkt die Qualität also deutlich – um über 30 %.<br />
+Im Durchschnitt haben Haushalte <strong>15,1 Stunden Strom pro Tag</strong> (≈ 63 %). Einige Regionen, wie Diskit, nur rund 4 Stunden.</p>
+<p>Etwa 95 % der Haushalte besitzen funktionierende Stromzähler.</p>
+<p>Ein weiteres Ziel war herauszufinden, <strong>was Menschen dazu bewegt, Strom zu teilen oder zu verschieben</strong>.<br />
+Ohne zusätzliche Information lag die Bereitschaft zur Verzögerung des Verbrauchs bei 5,5 / 10 – mit Aussicht auf Kostenvorteile stieg sie auf 6,9.</p>
<h2 id="Simulation">Simulation</h2>
-<p>After collecting all the estimated electric appliances of the local population, I simulated the use of 200 Solar Panels with 300Wp each, once for simultaneous electricity use, and once for mitigated electricity peaks through smart optimization and electricity usage delay.
-<img src="/images/sam_sim.png" alt="SAM Simulation of a local solar system " />
-<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimized" /></p>
-<p>Although solar is definitely not the optimal choice here and generates lots of issues with energy storage and battery charging at negative degrees, we figured that this was the way to go for the project.
-And as you can see, optimizing peak usage can improve solar from generating only one-fifth of the demand in winter to about half the demand in winter. Keeping in mind here, that the added solar farm was only intended to supply additional energy and not replace existing solutions, such a "small" farm would be a real lifesaver there and optimize the limited space in extremely mountainous terrain.</p>
-<h2 id="Closing_words">Closing words</h2>
-<p>There are to sides which the problems can be tackled: we can bring the total energy production up, by adding more panels or electricity by other means, but we can also try and bring the total demand down. This is to be achieved by investing strictly in the most energy-efficient appliances. Even replacing older, not-so-efficient appliances might sometimes be of use.
-But ensuring efficient use is not the only way to bring down the overall demand.</p>
-<p>As introduced as core ideas for the whole project, sharing and delaying will prove immensely useful. How so?
-By sharing, we mean a concept that is already widely applied in the relevant areas. What to do in a Village that has no access to water? Will we send each household out to the faraway river to catch water for their family? Or would we join hands in a community effort to dig a central well used by everyone?</p>
-<p>So, when we look at sharing electricity, how would we apply the concept? We take the appliances that consume the most energy individually and scale them up in order to increase efficiency. For example, in our case, that is most applicable to electric heating. If we manage to heat central community spaces available for everyone, naturally, fewer individual rooms will have to be heated. Similarly, one could declare a room as a public cinema, where people come together and watch Tv on a big Projector. Twice as fun, and conserving a great deal of energy again. Such ideas and others have to be realized in order to be able to match the total demand with the available supply.</p>
-<p>Sadly, the project was never taken up further, and the situation for the people in the Spiti Valley has not improved. Two years ago, a road directly through the mountains was finished, making the population hopeful for an increase in tourism, increasing the chances of the economic viability of improved solutions.
-I spent my time there in the function of a research intern, having no real say in the realization of the project. The problem remains, and I still think that decentral solutions look to be the most promising for this specific location. Of course, the Himalayas present a bit of an extreme location, but that doesn't change the fact that people live there and have a basic human right to electricity.</p>
+<p>Basierend auf den Daten simulierte ich den Einsatz von <strong>200 Solarmodulen à 300 Wp</strong>, einmal mit und einmal ohne intelligente Laststeuerung.</p>
+<p><img src="/images/sam_sim.png" alt="SAM Simulation eines lokalen Solarsystems" /><br />
+<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimiert" /></p>
+<p>Auch wenn Solar nicht optimal ist – vor allem wegen Kälte und Batterielagerung – zeigte sich, dass <strong>intelligente Lastverteilung</strong> den nutzbaren Ertrag im Winter von einem Fünftel auf etwa die Hälfte steigern kann.</p>
+<h2 id="Schlusswort">Schlusswort</h2>
+<p>Das Problem lässt sich aus zwei Richtungen angehen:</p>
+<ol>
+<li><strong>Produktion erhöhen</strong> – mehr Module, mehr Energiequellen.</li>
+<li><strong>Verbrauch senken</strong> – effizientere Geräte, gemeinschaftliche Nutzung.</li>
+</ol>
+<p>Das Konzept des <strong>Teilens und Verzögerns</strong> ist zentral. Wie bei einem gemeinschaftlich genutzten Brunnen kann auch Strom gemeinschaftlich erzeugt und genutzt werden.<br />
+Gemeinsam beheizte Räume oder öffentliche Projekträume sparen Energie und fördern Gemeinschaft.</p>
+<p>Leider wurde das Projekt nie weitergeführt, und die Situation im Spiti-Tal hat sich kaum verbessert. Eine neue Bergstraße gibt Hoffnung auf mehr Tourismus – und damit auf wirtschaftlich tragfähige Lösungen.</p>
+<p>Ich selbst war als Forschungspraktikant beteiligt, ohne Einfluss auf die Umsetzung. Dennoch bin ich überzeugt, dass <strong>dezentrale Lösungen</strong> der richtige Weg sind – gerade für extreme Regionen wie den Himalaya.<br />
+Denn eines bleibt wahr: <strong>Elektrizität ist ein Menschenrecht.</strong></p>

-<p>By prioritizing energy usage cases, instead of a full blackout during a storm, essential functions like radio towers and hospitals could be partially powered and maybe stay functioning. The binarity of either having electricity or not would be replaced by assigned quantities and timeslots, in a collective effort to be mindful and distribute the electricity necessity-based.
-The ultimate vision was a live predictive electricity market, where people could even earn money by selling their allotted, but not needed electricity.
-To gauge feasibility, I conducted several psychological acceptance studies and collected data on local electricity demands.
-I simulated a typical day of electricity demand in the Key monastery and the surrounding villages and mapped out the potential to install cost-efficient smart microgrid controllers enabling such an accurate and predictive behavior.
-The smart grid operator boxes available here in Germany cost several hundred, with installation several thousand Euros, not a feasible solution for the Indian population. Instead, we wanted to use Raspberry Pi's, which are interconnected through ethernet cables or local mesh networking.</p>

-<h2 id="Data_Collection">Data Collection</h2>
-<p>Building a questionnaire and visiting public schools during their English Classes, I had the chance to speak to a range of teenagers, answering questions about the state of electricity in their homes, generating more data than I could have accomplished running from door to door without any skills speaking local dialects. The questionnaire was as scientific as I could make it in such a situation and geared towards finding the type and number of electric devices in the homes and estimating typical usage scenarios.</p>
-<p>With a total of 145 participants from more than 6 different schools and roughly 4 different districts, all located in the Indian part of the Himalayas, the findings are as follows:</p>
-<p>The participants range from 11 to 53 years, with an average of 17 years.
-The average household has 6 members with an average of 5 smart devices. Only 2 percent of the Households had not a single smart device, but at the same time, only 42 percent had direct or indirect access to a laptop or computer. So the main body of smart devices consists of smartphones with a negligible portion of tablets.
-The average total amount of electrical devices is around 11 electrical appliances per house.</p>
-<p><strong>Subjective</strong> Quality Rating on a scale of 1 to 10:</p>
+<p>Das ist <strong>Tashi Gang</strong>, ein Dorf nahe des Klosters. Es beherbergt rund 50 Menschen und ist nur drei bis vier Monate im Sommer über eine Straße erreichbar. Den Rest des Jahres sind die Bewohner auf Hubschrauber-Erste-Hilfe angewiesen – erreichbar nur über einen funktionierenden Mobilfunkturm.</p>

+<h2 id="Das_Projekt">Das Projekt</h2>
+<p>In einer Umgebung, die auf Wasser- und Sonnenenergie angewiesen ist, mit über sechs Monaten Schnee, häufigen Schneestürmen und Temperaturen bis zu –35 °C, ist die Netzsicherung schwierig.</p>
+<p>Unser Ansatz war es, die im Westen etablierte Vorstellung von Elektrizität als homogenes, zentral erzeugtes Produkt zu hinterfragen und stattdessen die Möglichkeiten eines <strong>prädiktiven, sich selbst korrigierenden und dezentralen Netzes</strong> zu erforschen.</p>
+<p>Anstatt bei einem Sturm einen kompletten Blackout zu riskieren, könnten bei einer Priorisierung der Energieverwendung wichtige Funktionen – etwa Radiotürme oder Krankenhäuser – teilweise weiterbetrieben werden. Die Binarität von Strom / kein Strom würde durch ein System von <strong>Zuteilungen nach Bedarf und Zeitfenstern</strong> ersetzt.<br />
+Langfristig war die Vision ein <strong>lokaler, prädiktiver Strommarkt</strong>, bei dem Menschen überschüssige Energie verkaufen können.</p>
+<p>Zur Machbarkeitsprüfung führte ich psychologische Akzeptanzstudien durch und sammelte Daten zum lokalen Stromverbrauch. Anschließend simulierte ich einen typischen Strombedarfstag im Key-Kloster und in den umliegenden Dörfern und entwickelte Konzepte für kostengünstige <strong>Smart-Microgrid-Controller</strong>.</p>
+<p>Die hier in Deutschland verfügbaren Netzsteuerboxen kosten mehrere Hundert bis Tausend Euro – keine realistische Lösung für die Bevölkerung vor Ort. Stattdessen planten wir <strong>Raspberry Pi-basierte Systeme</strong>, vernetzt über Ethernet oder lokale Mesh-Netze.</p>
+<h2 id="Forschung">Forschung</h2>
+<p><img src="/images/Key_Monastery_Spiti.png" alt="Das Stromnetz des Key-Klosters" /></p>
+<h2 id="Datenerhebung">Datenerhebung</h2>
+<p>Durch den Besuch öffentlicher Schulen im Englischunterricht konnte ich mit Jugendlichen über den Stromzustand in ihren Haushalten sprechen und umfangreiche Daten erheben. Insgesamt nahmen <strong>145 Teilnehmer aus über sechs Schulen</strong> in etwa <strong>vier Distrikten</strong> teil – alle im indischen Himalaya.</p>
+<p>Der Altersdurchschnitt lag bei 17 Jahren. Durchschnittlich leben 6 Personen pro Haushalt mit etwa 5 Smart-Geräten. Nur 2 % der Haushalte hatten gar keine, 42 % verfügten über Computer oder Laptops.</p>
<blockquote>
-<p>Average quality in summer: 7.1
-Average quality in monsoon: 5.6
-Average quality in autumn: 7.1
-Average quality in winter: 4.0</p>
+<p>Durchschnittliche Stromqualität (1 – 10):<br />
+Sommer: 7,1 Monsun: 5,6 Herbst: 7,1 Winter: 4,0</p>
</blockquote>
-<p>So, as you would expect, during winter, but also when it rains, the felt quality drops by more than 30 percent on average.
-As for the daily supply time, the average sits at 15.1 hours out of 24, meaning the people have electricity only for 62.9 percent of the time, some, as for example the people in Diskit only have a sad 4 hours of daily access. On top of that, this estimation does not account for the snowfalls in Spiti for example, where it is not uncommon to experience 3 consecutive days of powercut or more.
-As the Power Meter is supplied by the government, a solid 82 percent of the houses have a working power meter, if one assumes that the 13 percent who did not know whether they have a power meter, do have one, we can say that around 95% of the houses have a power meter.</p>
-<p>Another goal of the studies was to find out what would incline people to be caring and sharing with the available electricity, something rather unimaginable here in Germany.</p>
-<p>In general, the uninformed openness to delaying usage of electricity on a scale of 1-10 was around 5.5, with the additional information that a smart delay would cause an overall price reduction, the acceptance went up to 6.9, a good 14%. This implies that people would be a lot more inclined to give up conveniences if the benefits have a direct impact on them.</p>
+<p>Im Winter oder bei Regen sinkt die Qualität also deutlich – um über 30 %.<br />
+Im Durchschnitt haben Haushalte <strong>15,1 Stunden Strom pro Tag</strong> (≈ 63 %). Einige Regionen, wie Diskit, nur rund 4 Stunden.</p>
+<p>Etwa 95 % der Haushalte besitzen funktionierende Stromzähler.</p>
+<p>Ein weiteres Ziel war herauszufinden, <strong>was Menschen dazu bewegt, Strom zu teilen oder zu verschieben</strong>.<br />
+Ohne zusätzliche Information lag die Bereitschaft zur Verzögerung des Verbrauchs bei 5,5 / 10 – mit Aussicht auf Kostenvorteile stieg sie auf 6,9.</p>
<h2 id="Simulation">Simulation</h2>
-<p>After collecting all the estimated electric appliances of the local population, I simulated the use of 200 Solar Panels with 300Wp each, once for simultaneous electricity use, and once for mitigated electricity peaks through smart optimization and electricity usage delay.
-<img src="/images/sam_sim.png" alt="SAM Simulation of a local solar system " />
-<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimized" /></p>
-<p>Although solar is definitely not the optimal choice here and generates lots of issues with energy storage and battery charging at negative degrees, we figured that this was the way to go for the project.
-And as you can see, optimizing peak usage can improve solar from generating only one-fifth of the demand in winter to about half the demand in winter. Keeping in mind here, that the added solar farm was only intended to supply additional energy and not replace existing solutions, such a "small" farm would be a real lifesaver there and optimize the limited space in extremely mountainous terrain.</p>
-<h2 id="Closing_words">Closing words</h2>
-<p>There are to sides which the problems can be tackled: we can bring the total energy production up, by adding more panels or electricity by other means, but we can also try and bring the total demand down. This is to be achieved by investing strictly in the most energy-efficient appliances. Even replacing older, not-so-efficient appliances might sometimes be of use.
-But ensuring efficient use is not the only way to bring down the overall demand.</p>
-<p>As introduced as core ideas for the whole project, sharing and delaying will prove immensely useful. How so?
-By sharing, we mean a concept that is already widely applied in the relevant areas. What to do in a Village that has no access to water? Will we send each household out to the faraway river to catch water for their family? Or would we join hands in a community effort to dig a central well used by everyone?</p>
-<p>So, when we look at sharing electricity, how would we apply the concept? We take the appliances that consume the most energy individually and scale them up in order to increase efficiency. For example, in our case, that is most applicable to electric heating. If we manage to heat central community spaces available for everyone, naturally, fewer individual rooms will have to be heated. Similarly, one could declare a room as a public cinema, where people come together and watch Tv on a big Projector. Twice as fun, and conserving a great deal of energy again. Such ideas and others have to be realized in order to be able to match the total demand with the available supply.</p>
-<p>Sadly, the project was never taken up further, and the situation for the people in the Spiti Valley has not improved. Two years ago, a road directly through the mountains was finished, making the population hopeful for an increase in tourism, increasing the chances of the economic viability of improved solutions.
-I spent my time there in the function of a research intern, having no real say in the realization of the project. The problem remains, and I still think that decentral solutions look to be the most promising for this specific location. Of course, the Himalayas present a bit of an extreme location, but that doesn't change the fact that people live there and have a basic human right to electricity.</p>
+<p>Basierend auf den Daten simulierte ich den Einsatz von <strong>200 Solarmodulen à 300 Wp</strong>, einmal mit und einmal ohne intelligente Laststeuerung.</p>
+<p><img src="/images/sam_sim.png" alt="SAM Simulation eines lokalen Solarsystems" /><br />
+<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimiert" /></p>
+<p>Auch wenn Solar nicht optimal ist – vor allem wegen Kälte und Batterielagerung – zeigte sich, dass <strong>intelligente Lastverteilung</strong> den nutzbaren Ertrag im Winter von einem Fünftel auf etwa die Hälfte steigern kann.</p>
+<h2 id="Schlusswort">Schlusswort</h2>
+<p>Das Problem lässt sich aus zwei Richtungen angehen:</p>
+<ol>
+<li><strong>Produktion erhöhen</strong> – mehr Module, mehr Energiequellen.</li>
+<li><strong>Verbrauch senken</strong> – effizientere Geräte, gemeinschaftliche Nutzung.</li>
+</ol>
+<p>Das Konzept des <strong>Teilens und Verzögerns</strong> ist zentral. Wie bei einem gemeinschaftlich genutzten Brunnen kann auch Strom gemeinschaftlich erzeugt und genutzt werden.<br />
+Gemeinsam beheizte Räume oder öffentliche Projekträume sparen Energie und fördern Gemeinschaft.</p>
+<p>Leider wurde das Projekt nie weitergeführt, und die Situation im Spiti-Tal hat sich kaum verbessert. Eine neue Bergstraße gibt Hoffnung auf mehr Tourismus – und damit auf wirtschaftlich tragfähige Lösungen.</p>
+<p>Ich selbst war als Forschungspraktikant beteiligt, ohne Einfluss auf die Umsetzung. Dennoch bin ich überzeugt, dass <strong>dezentrale Lösungen</strong> der richtige Weg sind – gerade für extreme Regionen wie den Himalaya.<br />
+Denn eines bleibt wahr: <strong>Elektrizität ist ein Menschenrecht.</strong></p>

-<p>Access to Electricity is a basic human right. At first, that may seem over the top, but if one stops to think what all the little tasks that electricity can indirectly handle for us (lightning, laundry, cooking, freezing, heating, entertaining…) would consume in time and effort if we had to perform them manually, this idea becomes very clear. There are globally around 1 billion people without tier 2 access to electricity.</p>
-<p><a href="https://sdgs.un.org/goals/goal7">SDGS Goal 7</a></p>
-<p><img src="/assets/images/electricity_tiers.png" alt="The electricity tiers defined by the UN" /></p>
-<p>People only know the intensity of labor that goes into everything when there is no electricity. And it is not even only about convenience, electricity is an enormous lifesaver in any number of scenarios, think just of hospitals or mobile phone networks that would be rendered completely useless without it. So we can easily agree on a need, a demand for electricity globally, for every person. But what about the supply? Why is there 1 billion undersupplied?
-The Answer: missing profitability. It would be a charity project to supply every last person on earth, not a profitable one. And while charitable projects are noble and should be pursued, the reality within capitalism shows that this is not the way it is going to happen.
-But what if we could come up with technology, or rather, a communal structure, that enables us to supply profitably, and still adapt to both, the difficult external factors (weather issues, remoteness, altitude, etc.) and the smaller purses of the undersupplied?</p>
-<h3 id="Location">Location</h3>
-<p>Towards the end of 2018, I spent 4 months in northern India, on a research project with the IIT Kharagpur.
-The goal was to work on one of the 17 UN-defined sustainable development goals – electricity.</p>
-<p>Worldwide, an estimated 1 billion people have no or insubstantial access to the grid.
-Some of them live here, in the Key Monastery in the Spiti Valley at around 3500 meters altitude.</p>

+<p>Zugang zu Elektrizität ist ein grundlegendes Menschenrecht. Das mag zunächst übertrieben klingen, doch wenn man bedenkt, wie viele kleine Aufgaben der Strom uns indirekt abnimmt – Licht, Wäsche, Kochen, Kühlen, Heizen, Unterhaltung – wird schnell klar, wie viel Zeit und Aufwand ohne Elektrizität nötig wäre. Weltweit leben etwa <strong>eine Milliarde Menschen</strong> ohne Zugang zu Strom auf dem sogenannten Tier-2-Level.</p>

+<p>Menschen erkennen erst dann, wie viel Arbeit in alltäglichen Dingen steckt, wenn sie keinen Strom haben. Doch es geht dabei nicht nur um Bequemlichkeit – Elektrizität rettet Leben: Krankenhäuser, Telekommunikation, Kühlung von Medikamenten – all das hängt davon ab.<br />
+Warum also sind immer noch so viele Menschen unterversorgt?<br />
+<strong>Die Antwort: fehlende Rentabilität.</strong> Es wäre ein wohltätiges, aber kein profitables Projekt, jede Person auf der Welt zu versorgen. Doch was, wenn wir eine Struktur finden könnten, die <strong>wirtschaftlich tragfähig</strong> ist und sich gleichzeitig an schwierige Bedingungen (Wetter, Abgeschiedenheit, Höhenlage) sowie an kleinere Einkommen anpassen kann?</p>

-<h2 id="The_Project">The Project</h2>
-<p>In an environment reliant on hydro-energy and solar (diesel transport is unreliable due to snowed-in mountain roads), over 6 months of snowy winter, frequent snowstorms, and temperatures of up to -35°C, securing the grid is hard.</p>
-<p>Our way to tackle the issue was to reject the in the western society very established notion of electricity as a homogenous product with centralized production and instead researched the possibilities of a predictive, self-correcting, and decentral grid.</p>
-<p>By prioritizing energy usage cases, instead of a full blackout during a storm, essential functions like radio towers and hospitals could be partially powered and maybe stay functioning. The binarity of either having electricity or not would be replaced by assigned quantities and timeslots, in a collective effort to be mindful and distribute the electricity necessity-based.
-The ultimate vision was a live predictive electricity market, where people could even earn money by selling their allotted, but not needed electricity.
-To gauge feasibility, I conducted several psychological acceptance studies and collected data on local electricity demands.
-I simulated a typical day of electricity demand in the Key monastery and the surrounding villages and mapped out the potential to install cost-efficient smart microgrid controllers enabling such an accurate and predictive behavior.
-The smart grid operator boxes available here in Germany cost several hundred, with installation several thousand Euros, not a feasible solution for the Indian population. Instead, we wanted to use Raspberry Pi's, which are interconnected through ethernet cables or local mesh networking.</p>

-<h2 id="Data_Collection">Data Collection</h2>
-<p>Building a questionnaire and visiting public schools during their English Classes, I had the chance to speak to a range of teenagers, answering questions about the state of electricity in their homes, generating more data than I could have accomplished running from door to door without any skills speaking local dialects. The questionnaire was as scientific as I could make it in such a situation and geared towards finding the type and number of electric devices in the homes and estimating typical usage scenarios.</p>
-<p>With a total of 145 participants from more than 6 different schools and roughly 4 different districts, all located in the Indian part of the Himalayas, the findings are as follows:</p>
-<p>The participants range from 11 to 53 years, with an average of 17 years.
-The average household has 6 members with an average of 5 smart devices. Only 2 percent of the Households had not a single smart device, but at the same time, only 42 percent had direct or indirect access to a laptop or computer. So the main body of smart devices consists of smartphones with a negligible portion of tablets.
-The average total amount of electrical devices is around 11 electrical appliances per house.</p>
-<p><strong>Subjective</strong> Quality Rating on a scale of 1 to 10:</p>
+<p>Das ist <strong>Tashi Gang</strong>, ein Dorf nahe des Klosters. Es beherbergt rund 50 Menschen und ist nur drei bis vier Monate im Sommer über eine Straße erreichbar. Den Rest des Jahres sind die Bewohner auf Hubschrauber-Erste-Hilfe angewiesen – erreichbar nur über einen funktionierenden Mobilfunkturm.</p>

+<h2 id="Das_Projekt">Das Projekt</h2>
+<p>In einer Umgebung, die auf Wasser- und Sonnenenergie angewiesen ist, mit über sechs Monaten Schnee, häufigen Schneestürmen und Temperaturen bis zu –35 °C, ist die Netzsicherung schwierig.</p>
+<p>Unser Ansatz war es, die im Westen etablierte Vorstellung von Elektrizität als homogenes, zentral erzeugtes Produkt zu hinterfragen und stattdessen die Möglichkeiten eines <strong>prädiktiven, sich selbst korrigierenden und dezentralen Netzes</strong> zu erforschen.</p>
+<p>Anstatt bei einem Sturm einen kompletten Blackout zu riskieren, könnten bei einer Priorisierung der Energieverwendung wichtige Funktionen – etwa Radiotürme oder Krankenhäuser – teilweise weiterbetrieben werden. Die Binarität von Strom / kein Strom würde durch ein System von <strong>Zuteilungen nach Bedarf und Zeitfenstern</strong> ersetzt.<br />
+Langfristig war die Vision ein <strong>lokaler, prädiktiver Strommarkt</strong>, bei dem Menschen überschüssige Energie verkaufen können.</p>
+<p>Zur Machbarkeitsprüfung führte ich psychologische Akzeptanzstudien durch und sammelte Daten zum lokalen Stromverbrauch. Anschließend simulierte ich einen typischen Strombedarfstag im Key-Kloster und in den umliegenden Dörfern und entwickelte Konzepte für kostengünstige <strong>Smart-Microgrid-Controller</strong>.</p>
+<p>Die hier in Deutschland verfügbaren Netzsteuerboxen kosten mehrere Hundert bis Tausend Euro – keine realistische Lösung für die Bevölkerung vor Ort. Stattdessen planten wir <strong>Raspberry Pi-basierte Systeme</strong>, vernetzt über Ethernet oder lokale Mesh-Netze.</p>
+<h2 id="Forschung">Forschung</h2>
+<p><img src="/images/Key_Monastery_Spiti.png" alt="Das Stromnetz des Key-Klosters" /></p>
+<h2 id="Datenerhebung">Datenerhebung</h2>
+<p>Durch den Besuch öffentlicher Schulen im Englischunterricht konnte ich mit Jugendlichen über den Stromzustand in ihren Haushalten sprechen und umfangreiche Daten erheben. Insgesamt nahmen <strong>145 Teilnehmer aus über sechs Schulen</strong> in etwa <strong>vier Distrikten</strong> teil – alle im indischen Himalaya.</p>
+<p>Der Altersdurchschnitt lag bei 17 Jahren. Durchschnittlich leben 6 Personen pro Haushalt mit etwa 5 Smart-Geräten. Nur 2 % der Haushalte hatten gar keine, 42 % verfügten über Computer oder Laptops.</p>
<blockquote>
-<p>Average quality in summer: 7.1
-Average quality in monsoon: 5.6
-Average quality in autumn: 7.1
-Average quality in winter: 4.0</p>
+<p>Durchschnittliche Stromqualität (1 – 10):<br />
+Sommer: 7,1 Monsun: 5,6 Herbst: 7,1 Winter: 4,0</p>
</blockquote>
-<p>So, as you would expect, during winter, but also when it rains, the felt quality drops by more than 30 percent on average.
-As for the daily supply time, the average sits at 15.1 hours out of 24, meaning the people have electricity only for 62.9 percent of the time, some, as for example the people in Diskit only have a sad 4 hours of daily access. On top of that, this estimation does not account for the snowfalls in Spiti for example, where it is not uncommon to experience 3 consecutive days of powercut or more.
-As the Power Meter is supplied by the government, a solid 82 percent of the houses have a working power meter, if one assumes that the 13 percent who did not know whether they have a power meter, do have one, we can say that around 95% of the houses have a power meter.</p>
-<p>Another goal of the studies was to find out what would incline people to be caring and sharing with the available electricity, something rather unimaginable here in Germany.</p>
-<p>In general, the uninformed openness to delaying usage of electricity on a scale of 1-10 was around 5.5, with the additional information that a smart delay would cause an overall price reduction, the acceptance went up to 6.9, a good 14%. This implies that people would be a lot more inclined to give up conveniences if the benefits have a direct impact on them.</p>
+<p>Im Winter oder bei Regen sinkt die Qualität also deutlich – um über 30 %.<br />
+Im Durchschnitt haben Haushalte <strong>15,1 Stunden Strom pro Tag</strong> (≈ 63 %). Einige Regionen, wie Diskit, nur rund 4 Stunden.</p>
+<p>Etwa 95 % der Haushalte besitzen funktionierende Stromzähler.</p>
+<p>Ein weiteres Ziel war herauszufinden, <strong>was Menschen dazu bewegt, Strom zu teilen oder zu verschieben</strong>.<br />
+Ohne zusätzliche Information lag die Bereitschaft zur Verzögerung des Verbrauchs bei 5,5 / 10 – mit Aussicht auf Kostenvorteile stieg sie auf 6,9.</p>
<h2 id="Simulation">Simulation</h2>
-<p>After collecting all the estimated electric appliances of the local population, I simulated the use of 200 Solar Panels with 300Wp each, once for simultaneous electricity use, and once for mitigated electricity peaks through smart optimization and electricity usage delay.
-<img src="/images/sam_sim.png" alt="SAM Simulation of a local solar system " />
-<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimized" /></p>
-<p>Although solar is definitely not the optimal choice here and generates lots of issues with energy storage and battery charging at negative degrees, we figured that this was the way to go for the project.
-And as you can see, optimizing peak usage can improve solar from generating only one-fifth of the demand in winter to about half the demand in winter. Keeping in mind here, that the added solar farm was only intended to supply additional energy and not replace existing solutions, such a "small" farm would be a real lifesaver there and optimize the limited space in extremely mountainous terrain.</p>
-<h2 id="Closing_words">Closing words</h2>
-<p>There are to sides which the problems can be tackled: we can bring the total energy production up, by adding more panels or electricity by other means, but we can also try and bring the total demand down. This is to be achieved by investing strictly in the most energy-efficient appliances. Even replacing older, not-so-efficient appliances might sometimes be of use.
-But ensuring efficient use is not the only way to bring down the overall demand.</p>
-<p>As introduced as core ideas for the whole project, sharing and delaying will prove immensely useful. How so?
-By sharing, we mean a concept that is already widely applied in the relevant areas. What to do in a Village that has no access to water? Will we send each household out to the faraway river to catch water for their family? Or would we join hands in a community effort to dig a central well used by everyone?</p>
-<p>So, when we look at sharing electricity, how would we apply the concept? We take the appliances that consume the most energy individually and scale them up in order to increase efficiency. For example, in our case, that is most applicable to electric heating. If we manage to heat central community spaces available for everyone, naturally, fewer individual rooms will have to be heated. Similarly, one could declare a room as a public cinema, where people come together and watch Tv on a big Projector. Twice as fun, and conserving a great deal of energy again. Such ideas and others have to be realized in order to be able to match the total demand with the available supply.</p>
-<p>Sadly, the project was never taken up further, and the situation for the people in the Spiti Valley has not improved. Two years ago, a road directly through the mountains was finished, making the population hopeful for an increase in tourism, increasing the chances of the economic viability of improved solutions.
-I spent my time there in the function of a research intern, having no real say in the realization of the project. The problem remains, and I still think that decentral solutions look to be the most promising for this specific location. Of course, the Himalayas present a bit of an extreme location, but that doesn't change the fact that people live there and have a basic human right to electricity.</p>
+<p>Basierend auf den Daten simulierte ich den Einsatz von <strong>200 Solarmodulen à 300 Wp</strong>, einmal mit und einmal ohne intelligente Laststeuerung.</p>
+<p><img src="/images/sam_sim.png" alt="SAM Simulation eines lokalen Solarsystems" /><br />
+<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimiert" /></p>
+<p>Auch wenn Solar nicht optimal ist – vor allem wegen Kälte und Batterielagerung – zeigte sich, dass <strong>intelligente Lastverteilung</strong> den nutzbaren Ertrag im Winter von einem Fünftel auf etwa die Hälfte steigern kann.</p>
+<h2 id="Schlusswort">Schlusswort</h2>
+<p>Das Problem lässt sich aus zwei Richtungen angehen:</p>
+<ol>
+<li><strong>Produktion erhöhen</strong> – mehr Module, mehr Energiequellen.</li>
+<li><strong>Verbrauch senken</strong> – effizientere Geräte, gemeinschaftliche Nutzung.</li>
+</ol>
+<p>Das Konzept des <strong>Teilens und Verzögerns</strong> ist zentral. Wie bei einem gemeinschaftlich genutzten Brunnen kann auch Strom gemeinschaftlich erzeugt und genutzt werden.<br />
+Gemeinsam beheizte Räume oder öffentliche Projekträume sparen Energie und fördern Gemeinschaft.</p>
+<p>Leider wurde das Projekt nie weitergeführt, und die Situation im Spiti-Tal hat sich kaum verbessert. Eine neue Bergstraße gibt Hoffnung auf mehr Tourismus – und damit auf wirtschaftlich tragfähige Lösungen.</p>
+<p>Ich selbst war als Forschungspraktikant beteiligt, ohne Einfluss auf die Umsetzung. Dennoch bin ich überzeugt, dass <strong>dezentrale Lösungen</strong> der richtige Weg sind – gerade für extreme Regionen wie den Himalaya.<br />
+Denn eines bleibt wahr: <strong>Elektrizität ist ein Menschenrecht.</strong></p>

At first, that may seem over the top, but if one stops to think what all the little tasks that electricity can indirectly handle for us (lightning, laundry, cooking, freezing, heating, entertaining…) would consume in time and effort if we had to perform them manually, this idea becomes very clear. There are globally around 1 billion people without tier 2 access to electricity.</p>

-<p>People only know the intensity of labor that goes into everything when there is no electricity. And it is not even only about convenience, electricity is an enormous lifesaver in any number of scenarios, think just of hospitals or mobile phone networks that would be rendered completely useless without it. So we can easily agree on a need, a demand for electricity globally, for every person. But what about the supply? Why is there 1 billion undersupplied?
-The Answer: missing profitability. It would be a charity project to supply every last person on earth, not a profitable one. And while charitable projects are noble and should be pursued, the reality within capitalism shows that this is not the way it is going to happen.
-But what if we could come up with technology, or rather, a communal structure, that enables us to supply profitably, and still adapt to both, the difficult external factors (weather issues, remoteness, altitude, etc.) and the smaller purses of the undersupplied?</p>

-<p>Towards the end of 2018, I spent 4 months in northern India, on a research project with the IIT Kharagpur.
-The goal was to work on one of the 17 UN-defined sustainable development goals – electricity.</p>
-<p>Worldwide, an estimated 1 billion people have no or insubstantial access to the grid.
-Some of them live here, in the Key Monastery in the Spiti Valley at around 3500 meters altitude.</p>

+<p>Zugang zu Elektrizität ist ein grundlegendes Menschenrecht. Das mag zunächst übertrieben klingen, doch wenn man bedenkt, wie viele kleine Aufgaben der Strom uns indirekt abnimmt – Licht, Wäsche, Kochen, Kühlen, Heizen, Unterhaltung – wird schnell klar, wie viel Zeit und Aufwand ohne Elektrizität nötig wäre. Weltweit leben etwa <strong>eine Milliarde Menschen</strong> ohne Zugang zu Strom auf dem sogenannten Tier-2-Level.</p>

+<p>Menschen erkennen erst dann, wie viel Arbeit in alltäglichen Dingen steckt, wenn sie keinen Strom haben. Doch es geht dabei nicht nur um Bequemlichkeit – Elektrizität rettet Leben: Krankenhäuser, Telekommunikation, Kühlung von Medikamenten – all das hängt davon ab.<br />
+Warum also sind immer noch so viele Menschen unterversorgt?<br />
+<strong>Die Antwort: fehlende Rentabilität.</strong> Es wäre ein wohltätiges, aber kein profitables Projekt, jede Person auf der Welt zu versorgen. Doch was, wenn wir eine Struktur finden könnten, die <strong>wirtschaftlich tragfähig</strong> ist und sich gleichzeitig an schwierige Bedingungen (Wetter, Abgeschiedenheit, Höhenlage) sowie an kleinere Einkommen anpassen kann?</p>

-<h2 id="The_Project">The Project</h2>
-<p>In an environment reliant on hydro-energy and solar (diesel transport is unreliable due to snowed-in mountain roads), over 6 months of snowy winter, frequent snowstorms, and temperatures of up to -35°C, securing the grid is hard.</p>
-<p>Our way to tackle the issue was to reject the in the western society very established notion of electricity as a homogenous product with centralized production and instead researched the possibilities of a predictive, self-correcting, and decentral grid.</p>
-<p>By prioritizing energy usage cases, instead of a full blackout during a storm, essential functions like radio towers and hospitals could be partially powered and maybe stay functioning. The binarity of either having electricity or not would be replaced by assigned quantities and timeslots, in a collective effort to be mindful and distribute the electricity necessity-based.
-The ultimate vision was a live predictive electricity market, where people could even earn money by selling their allotted, but not needed electricity.
-To gauge feasibility, I conducted several psychological acceptance studies and collected data on local electricity demands.
-I simulated a typical day of electricity demand in the Key monastery and the surrounding villages and mapped out the potential to install cost-efficient smart microgrid controllers enabling such an accurate and predictive behavior.
-The smart grid operator boxes available here in Germany cost several hundred, with installation several thousand Euros, not a feasible solution for the Indian population. Instead, we wanted to use Raspberry Pi's, which are interconnected through ethernet cables or local mesh networking.</p>

-<h2 id="Data_Collection">Data Collection</h2>
-<p>Building a questionnaire and visiting public schools during their English Classes, I had the chance to speak to a range of teenagers, answering questions about the state of electricity in their homes, generating more data than I could have accomplished running from door to door without any skills speaking local dialects. The questionnaire was as scientific as I could make it in such a situation and geared towards finding the type and number of electric devices in the homes and estimating typical usage scenarios.</p>
-<p>With a total of 145 participants from more than 6 different schools and roughly 4 different districts, all located in the Indian part of the Himalayas, the findings are as follows:</p>
-<p>The participants range from 11 to 53 years, with an average of 17 years.
-The average household has 6 members with an average of 5 smart devices. Only 2 percent of the Households had not a single smart device, but at the same time, only 42 percent had direct or indirect access to a laptop or computer. So the main body of smart devices consists of smartphones with a negligible portion of tablets.
-The average total amount of electrical devices is around 11 electrical appliances per house.</p>
-<p><strong>Subjective</strong> Quality Rating on a scale of 1 to 10:</p>
+<p>Das ist <strong>Tashi Gang</strong>, ein Dorf nahe des Klosters. Es beherbergt rund 50 Menschen und ist nur drei bis vier Monate im Sommer über eine Straße erreichbar.

+<h2 id="Das_Projekt">Das Projekt</h2>
+<p>In einer Umgebung, die auf Wasser- und Sonnenenergie angewiesen ist, mit über sechs Monaten Schnee, häufigen Schneestürmen und Temperaturen bis zu –35 °C, ist die Netzsicherung schwierig.</p>
+<p>Unser Ansatz war es, die im Westen etablierte Vorstellung von Elektrizität als homogenes, zentral erzeugtes Produkt zu hinterfragen und stattdessen die Möglichkeiten eines <strong>prädiktiven, sich selbst korrigierenden und dezentralen Netzes</strong> zu erforschen.</p>
+<p>Anstatt bei einem Sturm einen kompletten Blackout zu riskieren, könnten bei einer Priorisierung der Energieverwendung wichtige Funktionen – etwa Radiotürme oder Krankenhäuser – teilweise weiterbetrieben werden. Die Binarität von Strom / kein Strom würde durch ein System von <strong>Zuteilungen nach Bedarf und Zeitfenstern</strong> ersetzt.<br />
+Langfristig war die Vision ein <strong>lokaler, prädiktiver Strommarkt</strong>, bei dem Menschen überschüssige Energie verkaufen können.</p>
+<p>Zur Machbarkeitsprüfung führte ich psychologische Akzeptanzstudien durch und sammelte Daten zum lokalen Stromverbrauch. Anschließend simulierte ich einen typischen Strombedarfstag im Key-Kloster und in den umliegenden Dörfern und entwickelte Konzepte für kostengünstige <strong>Smart-Microgrid-Controller</strong>.</p>
+<p>Die hier in Deutschland verfügbaren Netzsteuerboxen kosten mehrere Hundert bis Tausend Euro – keine realistische Lösung für die Bevölkerung vor Ort. Stattdessen planten wir <strong>Raspberry Pi-basierte Systeme</strong>, vernetzt über Ethernet oder lokale Mesh-Netze.</p>
+<h2 id="Forschung">Forschung</h2>
+<p><img src="/images/Key_Monastery_Spiti.png" alt="Das Stromnetz des Key-Klosters" /></p>
+<h2 id="Datenerhebung">Datenerhebung</h2>
+<p>Durch den Besuch öffentlicher Schulen im Englischunterricht konnte ich mit Jugendlichen über den Stromzustand in ihren Haushalten sprechen und umfangreiche Daten erheben. Insgesamt nahmen <strong>145 Teilnehmer aus über sechs Schulen</strong> in etwa <strong>vier Distrikten</strong> teil – alle im indischen Himalaya.</p>
+<p>Der Altersdurchschnitt lag bei 17 Jahren. Durchschnittlich leben 6 Personen pro Haushalt mit etwa 5 Smart-Geräten. Nur 2 % der Haushalte hatten gar keine, 42 % verfügten über Computer oder Laptops.</p>
<blockquote>
-<p>Average quality in summer: 7.1
-Average quality in monsoon: 5.6
-Average quality in autumn: 7.1
-Average quality in winter: 4.0</p>
+<p>Durchschnittliche Stromqualität (1 – 10):<br />
+Sommer: 7,1 Monsun: 5,6 Herbst: 7,1 Winter: 4,0</p>
</blockquote>
-<p>So, as you would expect, during winter, but also when it rains, the felt quality drops by more than 30 percent on average.
-As for the daily supply time, the average sits at 15.1 hours out of 24, meaning the people have electricity only for 62.9 percent of the time, some, as for example the people in Diskit only have a sad 4 hours of daily access. On top of that, this estimation does not account for the snowfalls in Spiti for example, where it is not uncommon to experience 3 consecutive days of powercut or more.
-As the Power Meter is supplied by the government, a solid 82 percent of the houses have a working power meter, if one assumes that the 13 percent who did not know whether they have a power meter, do have one, we can say that around 95% of the houses have a power meter.</p>
-<p>Another goal of the studies was to find out what would incline people to be caring and sharing with the available electricity, something rather unimaginable here in Germany.</p>
-<p>In general, the uninformed openness to delaying usage of electricity on a scale of 1-10 was around 5.5, with the additional information that a smart delay would cause an overall price reduction, the acceptance went up to 6.9, a good 14%. This implies that people would be a lot more inclined to give up conveniences if the benefits have a direct impact on them.</p>
+<p>Im Winter oder bei Regen sinkt die Qualität also deutlich – um über 30 %.<br />
+Im Durchschnitt haben Haushalte <strong>15,1 Stunden Strom pro Tag</strong> (≈ 63 %). Einige Regionen, wie Diskit, nur rund 4 Stunden.</p>
+<p>Etwa 95 % der Haushalte besitzen funktionierende Stromzähler.</p>
+<p>Ein weiteres Ziel war herauszufinden, <strong>was Menschen dazu bewegt, Strom zu teilen oder zu verschieben</strong>.<br />
+Ohne zusätzliche Information lag die Bereitschaft zur Verzögerung des Verbrauchs bei 5,5 / 10 – mit Aussicht auf Kostenvorteile stieg sie auf 6,9.</p>
<h2 id="Simulation">Simulation</h2>
-<p>After collecting all the estimated electric appliances of the local population, I simulated the use of 200 Solar Panels with 300Wp each, once for simultaneous electricity use, and once for mitigated electricity peaks through smart optimization and electricity usage delay.
-<img src="/images/sam_sim.png" alt="SAM Simulation of a local solar system " />
-<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimized" /></p>
-<p>Although solar is definitely not the optimal choice here and generates lots of issues with energy storage and battery charging at negative degrees, we figured that this was the way to go for the project.
-And as you can see, optimizing peak usage can improve solar from generating only one-fifth of the demand in winter to about half the demand in winter. Keeping in mind here, that the added solar farm was only intended to supply additional energy and not replace existing solutions, such a "small" farm would be a real lifesaver there and optimize the limited space in extremely mountainous terrain.</p>
-<h2 id="Closing_words">Closing words</h2>
-<p>There are to sides which the problems can be tackled: we can bring the total energy production up, by adding more panels or electricity by other means, but we can also try and bring the total demand down. This is to be achieved by investing strictly in the most energy-efficient appliances. Even replacing older, not-so-efficient appliances might sometimes be of use.
-But ensuring efficient use is not the only way to bring down the overall demand.</p>
-<p>As introduced as core ideas for the whole project, sharing and delaying will prove immensely useful. How so?
-By sharing, we mean a concept that is already widely applied in the relevant areas. What to do in a Village that has no access to water? Will we send each household out to the faraway river to catch water for their family? Or would we join hands in a community effort to dig a central well used by everyone?</p>
-<p>So, when we look at sharing electricity, how would we apply the concept? We take the appliances that consume the most energy individually and scale them up in order to increase efficiency. For example, in our case, that is most applicable to electric heating. If we manage to heat central community spaces available for everyone, naturally, fewer individual rooms will have to be heated. Similarly, one could declare a room as a public cinema, where people come together and watch Tv on a big Projector. Twice as fun, and conserving a great deal of energy again. Such ideas and others have to be realized in order to be able to match the total demand with the available supply.</p>
-<p>Sadly, the project was never taken up further, and the situation for the people in the Spiti Valley has not improved. Two years ago, a road directly through the mountains was finished, making the population hopeful for an increase in tourism, increasing the chances of the economic viability of improved solutions.
-I spent my time there in the function of a research intern, having no real say in the realization of the project. The problem remains, and I still think that decentral solutions look to be the most promising for this specific location. Of course, the Himalayas present a bit of an extreme location, but that doesn't change the fact that people live there and have a basic human right to electricity.</p>
+<p>Basierend auf den Daten simulierte ich den Einsatz von <strong>200 Solarmodulen à 300 Wp</strong>, einmal mit und einmal ohne intelligente Laststeuerung.</p>
+<p><img src="/images/sam_sim.png" alt="SAM Simulation eines lokalen Solarsystems" /><br />
+<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimiert" /></p>
+<p>Auch wenn Solar nicht optimal ist – vor allem wegen Kälte und Batterielagerung – zeigte sich, dass <strong>intelligente Lastverteilung</strong> den nutzbaren Ertrag im Winter von einem Fünftel auf etwa die Hälfte steigern kann.</p>
+<h2 id="Schlusswort">Schlusswort</h2>
+<p>Das Problem lässt sich aus zwei Richtungen angehen:</p>
+<ol>
+<li><strong>Produktion erhöhen</strong> – mehr Module, mehr Energiequellen.</li>
+<li><strong>Verbrauch senken</strong> – effizientere Geräte, gemeinschaftliche Nutzung.</li>
+</ol>
+<p>Das Konzept des <strong>Teilens und Verzögerns</strong> ist zentral. Wie bei einem gemeinschaftlich genutzten Brunnen kann auch Strom gemeinschaftlich erzeugt und genutzt werden.<br />
+Gemeinsam beheizte Räume oder öffentliche Projekträume sparen Energie und fördern Gemeinschaft.</p>
+<p>Leider wurde das Projekt nie weitergeführt, und die Situation im Spiti-Tal hat sich kaum verbessert. Eine neue Bergstraße gibt Hoffnung auf mehr Tourismus – und damit auf wirtschaftlich tragfähige Lösungen.</p>
+<p>Ich selbst war als Forschungspraktikant beteiligt, ohne Einfluss auf die Umsetzung. Dennoch bin ich überzeugt, dass <strong>dezentrale Lösungen</strong> der richtige Weg sind – gerade für extreme Regionen wie den Himalaya.<br />
+Denn eines bleibt wahr: <strong>Elektrizität ist ein Menschenrecht.</strong></p>

-<p>I love hosting, I love experimenting in the Kitchen. Starting with homebrews was a natural fit for me and during the first wave of Covid-19, I went the whole homebrewer’s route of bottle fermentation and small batches later elevating my game with larger batches of 50 liters and a pressure tank system.</p>
-<p>Starting out, I found it fascinating, how just 4 rather simple ingredients, malt, hops, water and yeast, can form such an incredible range of taste experiences. It was and still is, a tremendous learning experience, where one slowly has to accept not being able to control the process fully and find room for creativity.</p>
-<p>Why do I present such an unrelated non-academic hobby here? I simply do not regard it as unrelated, experimenting and optimizing a process and a workflow, creating optimal conditions for the yeast to do its job feels very similar to approaching a coding project.
-Yeast and what it does fascinates me. Every time I open the latch to release some pressure on the Tank I think of the awesome symbiotic relationships yeast has with humans and how many different strains live there together to create a unique, yet tailored flavor. Several ideas are floating around of changing the brewing process by capturing the created carbon dioxide and using it productively. I could see a car tire being filled with my beer gas, or an algae farm munching away on my CO2 byproducts. Within a closed-loop pressurized system, such ideas actually become realizable and I would love to explore them further.</p>
-<p>I am not yet an expert on algae, but I can manage with yeast and I believe they can coexist and create a more sustainable cycle of production.
-Young Henrys, a brewery in Australia is already incorporating algae into its industrial process:
-<a href="https://younghenrys.com/algae">The Algae project</a></p>
-<p>Such ideas do not come into the industry by themselves: I believe that art and the exploratory discovery of novel techniques are the same things. Good and inventive design can improve society and make steps towards sustainability. I want to be part of that and would love to find new ways of using yeast in other design contexts: See whether I can make them work in a closed circular system, make them calculate things for me, or simply making my next beer taste awesome with just the right amount of fizz.</p>

+<p>Ich liebe es zu veranstalten, ich liebe es, in der Küche zu experimentieren. Mit Homebrews zu starten, war für mich eine natürliche Entscheidung, und während der ersten Covid-19-Welle habe ich den kompletten Heimbräuerweg mit Flaschenfermentation und kleinen Chargen eingeschlagen, später habe ich mein Setup auf 50-Liter-Chargen mit Drucktank-System erweitert.</p>
+<p>Zu Beginn war ich fasziniert, wie aus nur <strong>vier einfachen Zutaten</strong> – Malz, Hopfen, Wasser und Hefe – ein so unglaubliches Spektrum an Geschmackserlebnissen entstehen kann. Es war und ist immer noch ein <strong>tremendales Lernprojekt</strong>, bei dem man langsam akzeptieren muss, dass man den Prozess nicht vollständig kontrollieren kann, und gleichzeitig Raum für Kreativität findet.</p>
+<p>Warum präsentiere ich dieses scheinbar nicht-akademische Hobby hier? Ich sehe es nicht als irrelevant an: <strong>Experimentieren und Optimieren eines Prozesses und Workflows</strong>, optimale Bedingungen für die Hefe zu schaffen, fühlt sich dem Ansatz eines Programmierprojekts sehr ähnlich an.</p>
+<p>Hefe und ihre Wirkung faszinieren mich. Jedes Mal, wenn ich den Verschluss öffne, um etwas Druck aus dem Tank abzulassen, denke ich an die erstaunlichen symbiotischen Beziehungen der Hefe mit Menschen und wie viele verschiedene Stämme zusammenleben, um einen einzigartigen, maßgeschneiderten Geschmack zu erzeugen.<br />
+Es gibt einige Ideen, den Brauprozess zu verändern, indem das erzeugte CO₂ aufgefangen und produktiv genutzt wird – z. B. ein Autoreifen gefüllt mit Biergas oder eine Algenfarm, die das CO₂ aufnimmt.

-<p>I love hosting, I love experimenting in the Kitchen. Starting with homebrews was a natural fit for me and during the first wave of Covid-19, I went the whole homebrewer’s route of bottle fermentation and small batches later elevating my game with larger batches of 50 liters and a pressure tank system.</p>
-<p>Starting out, I found it fascinating, how just 4 rather simple ingredients, malt, hops, water and yeast, can form such an incredible range of taste experiences. It was and still is, a tremendous learning experience, where one slowly has to accept not being able to control the process fully and find room for creativity.</p>
-<p>Why do I present such an unrelated non-academic hobby here? I simply do not regard it as unrelated, experimenting and optimizing a process and a workflow, creating optimal conditions for the yeast to do its job feels very similar to approaching a coding project.
-Yeast and what it does fascinates me. Every time I open the latch to release some pressure on the Tank I think of the awesome symbiotic relationships yeast has with humans and how many different strains live there together to create a unique, yet tailored flavor. Several ideas are floating around of changing the brewing process by capturing the created carbon dioxide and using it productively. I could see a car tire being filled with my beer gas, or an algae farm munching away on my CO2 byproducts. Within a closed-loop pressurized system, such ideas actually become realizable and I would love to explore them further.</p>
-<p>I am not yet an expert on algae, but I can manage with yeast and I believe they can coexist and create a more sustainable cycle of production.
-Young Henrys, a brewery in Australia is already incorporating algae into its industrial process:
-<a href="https://younghenrys.com/algae">The Algae project</a></p>
-<p>Such ideas do not come into the industry by themselves: I believe that art and the exploratory discovery of novel techniques are the same things. Good and inventive design can improve society and make steps towards sustainability. I want to be part of that and would love to find new ways of using yeast in other design contexts: See whether I can make them work in a closed circular system, make them calculate things for me, or simply making my next beer taste awesome with just the right amount of fizz.</p>

+<p>Ich liebe es zu veranstalten, ich liebe es, in der Küche zu experimentieren. Mit Homebrews zu starten, war für mich eine natürliche Entscheidung, und während der ersten Covid-19-Welle habe ich den kompletten Heimbräuerweg mit Flaschenfermentation und kleinen Chargen eingeschlagen, später habe ich mein Setup auf 50-Liter-Chargen mit Drucktank-System erweitert.</p>
+<p>Zu Beginn war ich fasziniert, wie aus nur <strong>vier einfachen Zutaten</strong> – Malz, Hopfen, Wasser und Hefe – ein so unglaubliches Spektrum an Geschmackserlebnissen entstehen kann. Es war und ist immer noch ein <strong>tremendales Lernprojekt</strong>, bei dem man langsam akzeptieren muss, dass man den Prozess nicht vollständig kontrollieren kann, und gleichzeitig Raum für Kreativität findet.</p>
+<p>Warum präsentiere ich dieses scheinbar nicht-akademische Hobby hier? Ich sehe es nicht als irrelevant an: <strong>Experimentieren und Optimieren eines Prozesses und Workflows</strong>, optimale Bedingungen für die Hefe zu schaffen, fühlt sich dem Ansatz eines Programmierprojekts sehr ähnlich an.</p>
+<p>Hefe und ihre Wirkung faszinieren mich. Jedes Mal, wenn ich den Verschluss öffne, um etwas Druck aus dem Tank abzulassen, denke ich an die erstaunlichen symbiotischen Beziehungen der Hefe mit Menschen und wie viele verschiedene Stämme zusammenleben, um einen einzigartigen, maßgeschneiderten Geschmack zu erzeugen.<br />
+Es gibt einige Ideen, den Brauprozess zu verändern, indem das erzeugte CO₂ aufgefangen und produktiv genutzt wird – z. B. ein Autoreifen gefüllt mit Biergas oder eine Algenfarm, die das CO₂ aufnimmt.

- <p>Being involved with 3D Printers, there is the issue of sustainability that I am confronted with regularly.
-Most 3D printed parts never get recycled and add to the global waste problem, rather than reducing it.
-The printer most certainly doesn’t care what it is printing, the main problem is the dimensional accuracy and the purity of the material. All of this leads to a huge industry, Germany being especially involved, using loads of virgin plastic.</p>
-<p>What can be done about it?
-We can design our products to last longer, we can also print recycling labels on them so they do not have to get burned after their first life. We can take care to only print functional objects, not just fun toys nobody uses.
-Yet, none of that prevents the use of virgin plastics. If you buy a spool of filament, there are some recycled options, but usually at twice the price at worse quality. No wonder recycled filament fails to convince the masses. It is mostly a fun thing YouTubers can pursue, not a valid commercial process.</p>
+ <p>Als 3D-Druck-Enthusiast sehe ich mich regelmäßig mit dem Thema Nachhaltigkeit konfrontiert.<br />
+Die meisten 3D-gedruckten Teile werden nie recycelt und tragen eher zum globalen Müllproblem bei, als es zu reduzieren.<br />
+Das Problem liegt weniger beim Drucker selbst als bei der <strong>dimensionalen Genauigkeit</strong> und der <strong>Reinheit des Materials</strong>. Dies führt zu einer riesigen Industrie, insbesondere in Deutschland, die enorme Mengen an <strong>Neukunststoff</strong> verbraucht.</p>
+<h3 id="Was_kann_man_tun?">Was kann man tun?</h3>
+<p>Wir können Produkte langlebiger gestalten, Recycling-Labels aufdrucken und nur funktionale Objekte drucken. Dennoch verhindert dies nicht die Nutzung von Neukunststoffen. Recycelter Filament ist oft doppelt so teuer bei schlechterer Qualität – kein Wunder, dass er kaum Verbreitung findet.</p>

-<p>In my opinion, the core problem is the nonexistent economic feasibility of a proper recycling process. Identifying the exact material of a piece of trash is a very hard problem, definitely not solved yet. So why do we mix the plastic up in the first place? There is a general willingness of people to recycle, but the system for it is missing.</p>
-<h1 id="The_Master_Plan">The Master Plan</h1>
-<p>I want to get people to wash and separate their trash for me, which are the most expensive steps in the recycling process. There is a willingness to take the extra step, and even if just my mom collects bottle caps for me, that is more than I can realistically use up.
-This only really works when I am thinking in a local and decentral environment.
-The existing recycling facilities clearly will not be able to provide 200 different containers for 200 different types of plastic.
-Starting the process with clean and sorted materials, like bottle caps (HDPE) or failed prints (PET-G), I start off with an advantage.
-Now I have to take apart the trash into evenly sized particles.

-<p>With these awesome open-source drawings, I was able to cobble together my very own very dangerous plastic shredder.</p>
-<p>After finding some way to drive this massive axis, I feed the beast and hopefully get tiny pretty uniform plastic bits that are ready to begin the cycle of life anew.</p>
-<p>The solution for the motorization was an old and used garden shredder that still had an intact motor and wiring.
-We cut it in half and attached it to the shredder box.</p>
+<p>Das Kernproblem ist die <strong>fehlende wirtschaftliche Machbarkeit</strong> eines echten Recyclings. Das exakte Identifizieren von Kunststoffarten ist extrem schwierig und noch ungelöst. Es gibt Bereitschaft zu recyceln, aber das System fehlt.</p>

-<p>After replacing the weak force transmission screw for an industrial coupler, we were ready to try it out. Obviously, there are still security concerns in this prototype, a proper hopper is already being made.</p>
-<p>Nevertheless, we are confident that this shredder will be able to deal with the light sorts of plastic we are thinking of.
-As you can see, I am now able to produce awesome confetti but to do more with the plastic flakes I have to extrude them.</p>
-<h2 id="Meet_the_Filastruder">Meet the Filastruder</h2>
-<p>This is the Filastruder, designed and made by Tim Elmore, in an attempt to create the cheapest viable way to extrude plastic. The biggest cost issue is the tight industrial tolerances in thickness that have to be adhered to. This is in essence what separates good from the bad filament. The industry standard nowadays is at +-0.03mm. Hard to achieve on a DIY setup, but not unheard of. The setup, like any bigger industry equivalent, consists of a motor pressing plastic pellets through a heated screw, extruding molten plastic at the end through a nozzle, and setting the diameter. The leftmost machine is responsible for winding the filament properly onto a spool.</p>
-<p>Here you can see the extrusion process in action.</p>

-<p>The Filastruder is controlled by an Arduino and is highly configurable. The laser sensor visible in the video is already working, but I am missing more direct control over the diameter of the filament.</p>
-<p>When it all really comes down to the single variable of the filament diameter responsible for the quality of my recycled project, a simple Machine Learning optimization directly jumps at me: I have a few variables like winder speed, extrusion speed, heat, and cooling intensity. These variables can be optimized on the fly for an exact diameter. This is actually roughly how virgin filament is produced, commercial facilities just manage much faster.</p>

-<p>So far, I am aware of a few companies and academic projects attempting this process, but none of them manage to get either the quality or the price of other products available. Automatization does not just take out jobs away, I think it can also be a helpful tool, for example tackling environmental issues such as this one.</p>
-<p>This project is very dear to my heart and I plan to investigate it further in the form of a master thesis.
-The realization will require many skills I am already picking up or still need to work on within the Design and Computation program.

- <h2 id="2020:_discovering_jekyll">2020: discovering jekyll</h2>
-<p>For applying to my master's program in 2020, a portfolio was required, and since it was more or less for a design program, I wanted to have a nice website.
-After trying for a month to get what I wanted out of WordPress, and angrily quitting multiple times, I discovered <a href="https://jekyllrb.com">Jekyll</a>.
-Back then, <a href="https://gohugo.io">Hugo</a> and <a href="https://www.11ty.dev">11ty</a> were the newer kids on the block, but I was heavily relying on the free hosting from <a href="https://pages.github.com">GitHub Pages</a>, where Jekyll was the easiest to integrate.</p>
-<p>Back then, looking for inspiration, I had an ethics professor I really liked, and he had a Jekyll site with the <a href="https://mmistakes.github.io/minimal-mistakes/">Minimal Mistakes</a> theme.
-<a href="https://rainermuehlhoff.de">Prof. Mühlhoff</a></p>
-<p>I went about using Minimal Mistakes, and it was a great experience.
-The resulting portfolio at least got me into the master's, and I fell in love with the general idea of being able to write sites in markdown, while a program would take care of the rest.</p>
-<p>For years, Jekyll was my go-to for building static websites.
-It was familiar, widely supported, and part of the broader Ruby ecosystem.
-But over time, my frustrations grew—slow builds, complicated plugin setups, and a dependency stack that never felt quite right.
-To be honest, many of the drawbacks were totally not Jekyll’s fault. It was just slow, otherwise fine. But especially using GitHub Pages imposed quite a few limitations on plugins and themes.
-Also, maybe I didn’t put in enough effort, but I could never really get theme modifications working. Just extending the theme to show multiple authors was a pain—although it was eventually working.</p>
-<p>On now finishing the master's, I wanted a visual overhaul, and while browsing for inspiration again, using Jekyll at all got questioned again.
-I knew I wanted a static site generator, because markdown is the shit.
-So after looking around further, <strong><a href="https://www.getzola.org/">Zola</a></strong> emerged—actually through a chatbot suggestion 😄</p>
-<p>Recently, I made the leap to Zola, a Rust-powered static site generator, and I don't see myself going back.</p>
-<hr />
-<h2 id="rust_feels_right">rust feels right</h2>
-<p>I’ve always admired <a href="https://www.rust-lang.org/">Rust</a> for its speed, safety, and modern tooling.
-Using a static site generator built with Rust just made sense. <strong>Zola is fast</strong>—blazing fast.
-Even during local development, rebuilds are near-instant, and that alone makes the writing process smoother and more enjoyable.</p>
-<p>Plus, using something written in Rust means fewer external dependencies, no bundler hell, and zero Ruby setup headaches.
-I can just download the binary, run it, and get going. It respects my time.</p>
-<hr />
-<h2 id="zola_is_thoughtfully_designed">zola is thoughtfully designed</h2>
-<p>Beyond performance, Zola is just really well designed.
-Its template syntax (thanks to <a href="https://tera.netlify.app">Tera</a>) is more powerful and readable than Liquid.
-The built-in shortcodes, pagination, and asset pipelines all feel cohesive and purposeful.
-There’s very little “configuration over convention” fatigue that Jekyll often gave me.</p>
-<p>And even though both systems are markdown-based, migrating wasn’t just a matter of copy-pasting files.
-I had to rethink frontmatter, adjust templates, and wrangle image paths and shortcodes.
-The structure and behavior are different enough that it felt like a real rebuild—not just a port.</p>
-<hr />
-<h2 id="duckquill_made_me_switch">duckquill made me switch</h2>
-<p>The real catalyst, though? <a href="https://github.com/daudix/duckquill"><strong>Duckquill</strong></a>, a stunning Zola theme built by <a href="https://github.com/daudix">Daudix</a>.
-It struck the perfect balance between minimalism and elegance—exactly the aesthetic I wanted but could never quite achieve with Jekyll.
-Duckquill didn’t just make Zola usable for me; it made it <em>irresistible</em>.</p>
-<p>What really sets <strong>Duckquill</strong> apart—beyond its clean typography and smart layout—is how well it supports a vision of digital autonomy.
-The theme comes with <strong>Mastodon-powered comments</strong>, allowing for lightweight, federated interaction without relying on big centralized platforms.
-This fits perfectly with my goal of reclaiming control through <strong>self-hosting</strong>.
-Whether it's running my own site, owning my content, or interacting through the fediverse, Duckquill reinforces those values rather than working against them.
-It’s a rare example of design and infrastructure aligning with personal principles.</p>
-<hr />
-<h2 id="final_thoughts">final thoughts</h2>
-<p>Switching from Jekyll to Zola wasn’t effortless, but it was absolutely worth it.
-I now have a faster, more reliable, and better-looking site that’s easier to maintain and feels like it fits my tooling philosophy.</p>
-<p>If you're feeling the weight of your current setup, maybe it's time to try Zola—and give Duckquill a spin while you're at it.</p>

- <p>Being involved with 3D Printers, there is the issue of sustainability that I am confronted with regularly.
-Most 3D printed parts never get recycled and add to the global waste problem, rather than reducing it.
-The printer most certainly doesn’t care what it is printing, the main problem is the dimensional accuracy and the purity of the material. All of this leads to a huge industry, Germany being especially involved, using loads of virgin plastic.</p>
-<p>What can be done about it?
-We can design our products to last longer, we can also print recycling labels on them so they do not have to get burned after their first life. We can take care to only print functional objects, not just fun toys nobody uses.
-Yet, none of that prevents the use of virgin plastics. If you buy a spool of filament, there are some recycled options, but usually at twice the price at worse quality. No wonder recycled filament fails to convince the masses. It is mostly a fun thing YouTubers can pursue, not a valid commercial process.</p>

-<p>In my opinion, the core problem is the nonexistent economic feasibility of a proper recycling process. Identifying the exact material of a piece of trash is a very hard problem, definitely not solved yet. So why do we mix the plastic up in the first place? There is a general willingness of people to recycle, but the system for it is missing.</p>
-<h1 id="The_Master_Plan">The Master Plan</h1>
-<p>I want to get people to wash and separate their trash for me, which are the most expensive steps in the recycling process. There is a willingness to take the extra step, and even if just my mom collects bottle caps for me, that is more than I can realistically use up.
-This only really works when I am thinking in a local and decentral environment.
-The existing recycling facilities clearly will not be able to provide 200 different containers for 200 different types of plastic.
-Starting the process with clean and sorted materials, like bottle caps (HDPE) or failed prints (PET-G), I start off with an advantage.
-Now I have to take apart the trash into evenly sized particles.

-<p>After finding some way to drive this massive axis, I feed the beast and hopefully get tiny pretty uniform plastic bits that are ready to begin the cycle of life anew.</p>
-<p>The solution for the motorization was an old and used garden shredder that still had an intact motor and wiring.

- <p>Being involved with 3D Printers, there is the issue of sustainability that I am confronted with regularly.
-Most 3D printed parts never get recycled and add to the global waste problem, rather than reducing it.
-The printer most certainly doesn’t care what it is printing, the main problem is the dimensional accuracy and the purity of the material. All of this leads to a huge industry, Germany being especially involved, using loads of virgin plastic.</p>
-<p>What can be done about it?
-We can design our products to last longer, we can also print recycling labels on them so they do not have to get burned after their first life. We can take care to only print functional objects, not just fun toys nobody uses.
-Yet, none of that prevents the use of virgin plastics. If you buy a spool of filament, there are some recycled options, but usually at twice the price at worse quality. No wonder recycled filament fails to convince the masses. It is mostly a fun thing YouTubers can pursue, not a valid commercial process.</p>
+ <p>Als 3D-Druck-Enthusiast sehe ich mich regelmäßig mit dem Thema Nachhaltigkeit konfrontiert.<br />
+Die meisten 3D-gedruckten Teile werden nie recycelt und tragen eher zum globalen Müllproblem bei, als es zu reduzieren.<br />
+Das Problem liegt weniger beim Drucker selbst als bei der <strong>dimensionalen Genauigkeit</strong> und der <strong>Reinheit des Materials</strong>. Dies führt zu einer riesigen Industrie, insbesondere in Deutschland, die enorme Mengen an <strong>Neukunststoff</strong> verbraucht.</p>
+<h3 id="Was_kann_man_tun?">Was kann man tun?</h3>
+<p>Wir können Produkte langlebiger gestalten, Recycling-Labels aufdrucken und nur funktionale Objekte drucken. Dennoch verhindert dies nicht die Nutzung von Neukunststoffen. Recycelter Filament ist oft doppelt so teuer bei schlechterer Qualität – kein Wunder, dass er kaum Verbreitung findet.</p>

-<p>In my opinion, the core problem is the nonexistent economic feasibility of a proper recycling process. Identifying the exact material of a piece of trash is a very hard problem, definitely not solved yet. So why do we mix the plastic up in the first place? There is a general willingness of people to recycle, but the system for it is missing.</p>
-<h1 id="The_Master_Plan">The Master Plan</h1>
-<p>I want to get people to wash and separate their trash for me, which are the most expensive steps in the recycling process. There is a willingness to take the extra step, and even if just my mom collects bottle caps for me, that is more than I can realistically use up.
-This only really works when I am thinking in a local and decentral environment.
-The existing recycling facilities clearly will not be able to provide 200 different containers for 200 different types of plastic.
-Starting the process with clean and sorted materials, like bottle caps (HDPE) or failed prints (PET-G), I start off with an advantage.
-Now I have to take apart the trash into evenly sized particles.
-Meet:</p>

-<p>With these awesome open-source drawings, I was able to cobble together my very own very dangerous plastic shredder.</p>
-<p>After finding some way to drive this massive axis, I feed the beast and hopefully get tiny pretty uniform plastic bits that are ready to begin the cycle of life anew.</p>
-<p>The solution for the motorization was an old and used garden shredder that still had an intact motor and wiring.
-We cut it in half and attached it to the shredder box.</p>
+<p>Das Kernproblem ist die <strong>fehlende wirtschaftliche Machbarkeit</strong> eines echten Recyclings. Das exakte Identifizieren von Kunststoffarten ist extrem schwierig und noch ungelöst. Es gibt Bereitschaft zu recyceln, aber das System fehlt.</p>

+<p>Ich möchte Menschen motivieren, ihren Müll <strong>zu waschen und zu sortieren</strong>, die teuersten Schritte im Recyclingprozess. Selbst kleine Beiträge, wie meine Mutter, die Flaschendeckel sammelt, sind wertvoll.<br />
+Dies funktioniert nur in einem <strong>lokalen, dezentralen Umfeld</strong>. Existierende Recyclinganlagen können nicht 200 verschiedene Kunststoffarten trennen.</p>
+<p>Mit sauberem, sortiertem Material – etwa Flaschendeckel (HDPE) oder fehlerhafte Drucke (PET-G) – starte ich bereits im Vorteil. Jetzt müssen die Teile noch in <strong>gleichmäßige Partikel</strong> zerkleinert werden.</p>

-<p>After replacing the weak force transmission screw for an industrial coupler, we were ready to try it out. Obviously, there are still security concerns in this prototype, a proper hopper is already being made.</p>
-<p>Nevertheless, we are confident that this shredder will be able to deal with the light sorts of plastic we are thinking of.
-As you can see, I am now able to produce awesome confetti but to do more with the plastic flakes I have to extrude them.</p>
-<h2 id="Meet_the_Filastruder">Meet the Filastruder</h2>
-<p>This is the Filastruder, designed and made by Tim Elmore, in an attempt to create the cheapest viable way to extrude plastic. The biggest cost issue is the tight industrial tolerances in thickness that have to be adhered to. This is in essence what separates good from the bad filament. The industry standard nowadays is at +-0.03mm. Hard to achieve on a DIY setup, but not unheard of. The setup, like any bigger industry equivalent, consists of a motor pressing plastic pellets through a heated screw, extruding molten plastic at the end through a nozzle, and setting the diameter. The leftmost machine is responsible for winding the filament properly onto a spool.</p>
-<p>Here you can see the extrusion process in action.</p>
+<p>Nach Austausch der schwachen Kraftübertragungsschraube gegen einen Industrie-Kuppler waren wir startklar. Sicherheit bleibt ein Thema, ein richtiger Trichter ist in Arbeit.</p>
+<h2 id="Der_Filastruder">Der Filastruder</h2>
+<p>Der <strong>Filastruder</strong>, entworfen von Tim Elmore, bietet eine kostengünstige Möglichkeit, Filament zu extrudieren.<br />
+Die größten Herausforderungen: <strong>präzise Durchmesserkontrolle</strong> ±0,03 mm, sonst schwankt die Qualität.</p>
+<p>Motor presst Kunststoffpellets durch eine beheizte Schraube, am Ende wird durch die Düse extrudiert und der Durchmesser eingestellt. Links wickelt die Maschine das Filament auf eine Spule.</p>

-<p>The Filastruder is controlled by an Arduino and is highly configurable. The laser sensor visible in the video is already working, but I am missing more direct control over the diameter of the filament.</p>
-<p>When it all really comes down to the single variable of the filament diameter responsible for the quality of my recycled project, a simple Machine Learning optimization directly jumps at me: I have a few variables like winder speed, extrusion speed, heat, and cooling intensity. These variables can be optimized on the fly for an exact diameter. This is actually roughly how virgin filament is produced, commercial facilities just manage much faster.</p>
-<p><img src="/assets/images/recycling_variables.png" alt="The variables in an iterative optimization" /></p>
-<p>So far, I am aware of a few companies and academic projects attempting this process, but none of them manage to get either the quality or the price of other products available. Automatization does not just take out jobs away, I think it can also be a helpful tool, for example tackling environmental issues such as this one.</p>
-<p>This project is very dear to my heart and I plan to investigate it further in the form of a master thesis.
-The realization will require many skills I am already picking up or still need to work on within the Design and Computation program.

-<p>While learning about 3D Printing, I was most intrigued by the possibility to modify and repair existing products. While there is an amazing community with lots of good and free models around, naturally I came to a point where I did not find what I was looking for readily designed. I realized this is an essential skill for effectively operating not just 3D Printers, but any productive machine really.</p>
-<p>Since youtube was the place I was learning all about 3D Printing, and all the people that I looked up to there were using Fusion 360 as their CAD Program that’s what I got into.
-In hindsight, that was a pretty good choice and I am in love with the abilities parametric design gives me.
-Below you will find some of my designs.
-The process is something that I enjoy a lot and wish to dive into deeper.</p>
-<p>By trial and error, I already learned a lot about designing specifically for 3D Printing, but I often feel that there are many aesthetic considerations in design that I am not familiar with.
-I want to broaden my general ability to design physical objects, which is something I hope to gain during my master’s.</p>

+<p>Beim Erlernen des 3D-Drucks hat mich vor allem die Möglichkeit fasziniert, bestehende Produkte zu verändern oder zu reparieren.<br />
+Auch wenn es eine großartige Community mit vielen guten und kostenlosen Modellen gibt, bin ich schnell an den Punkt gekommen, an dem ich nicht fand, was ich suchte.<br />
+Mir wurde klar, dass dies eine wesentliche Fähigkeit ist, um nicht nur 3D-Drucker, sondern grundsätzlich jede Art von Produktionsmaschine sinnvoll zu nutzen.</p>
+<p>Da ich alles über 3D-Druck auf YouTube gelernt habe und dort fast alle mit <strong>Fusion 360</strong> arbeiteten, habe ich mich ebenfalls dafür entschieden.<br />
+Rückblickend war das eine sehr gute Wahl – ich habe mich in die Möglichkeiten des <strong>parametrischen Designs</strong> verliebt.<br />
+Unten findest du einige meiner Entwürfe.<br />
+Der Prozess selbst macht mir unglaublich viel Spaß und ich möchte ihn noch weiter vertiefen.</p>
+<p>Durch Ausprobieren habe ich bereits viel darüber gelernt, wie man speziell für den 3D-Druck konstruiert.<br />
+Trotzdem habe ich oft das Gefühl, dass mir ein tieferes Verständnis für <strong>ästhetische Gestaltung</strong> fehlt.<br />
+Ich möchte meine generelle Fähigkeit erweitern, physische Objekte zu entwerfen – etwas, das ich mir im Masterstudium erhoffe.</p>

-<p>Besides coming up with new objects, incorporating the real world is also an interest of mine.</p>
-<h3 id="Interaction_with_real_objects_and_environments">Interaction with real objects and environments</h3>
-<p>In the last few years I have played around with a few smartphone cameras and was always quite sad, that my scans were never quite accurate enough to do cool stuff with them.
-I could not really afford real 3D scanner and had already started cobbling together a raspberry Pi camera with a cheap TOF sensor, which is a simple, but not quite as good replacement for a laser or a lidar sensor, but then Apple came out with the first phones with accessible Lidar sensor.
-Recently, through work at the university I got access to a device with a lidar sensor and started having fun with it.
-See some examples here:</p>

-<p>This last one was scanned with just my smartphone camera. You can see that the quality is notably worse, but considering is was created with just a single, run-of-the-mill smartphone sensor, I think it is still pretty impressive and will certainly do something towards democratizing such technologies and abilities.</p>

+<p>Neben dem Entwerfen neuer Objekte interessiert mich auch die Integration der <strong>realen Welt</strong> in meine Arbeit.</p>
+<h3 id="Interaktion_mit_realen_Objekten_und_Umgebungen">Interaktion mit realen Objekten und Umgebungen</h3>
+<p>In den letzten Jahren habe ich mit verschiedenen Smartphone-Kameras experimentiert – leider waren meine Scans meist nicht präzise genug, um wirklich etwas damit anzufangen.<br />
+Ein professioneller 3D-Scanner war zu teuer, also bastelte ich mir eine Kombination aus einer <strong>Raspberry-Pi-Kamera</strong> und einem günstigen <strong>TOF-Sensor</strong>.<br />
+Das Setup ist simpel, aber bei weitem nicht so genau wie Laser- oder LiDAR-Sensoren. Dann brachte Apple die ersten Geräte mit <strong>zugänglichem LiDAR</strong> heraus.</p>
+<p>Durch meine Arbeit an der Universität hatte ich schließlich Zugriff auf ein Gerät mit LiDAR und begann, damit zu experimentieren.<br />
+Ein paar Beispiele siehst du hier:</p>
+<div class="sketchfab-embed-wrapper"> <iframe title="DigiLab Hauptraum" frameborder="0" allowfullscreen mozallowfullscreen="true" webkitallowfullscreen="true" allow="autoplay; fullscreen; xr-spatial-tracking" xr-spatial-tracking execution-while-out-of-viewport execution-while-not-rendered web-share width="800" height="600" src="https://sketchfab.com/models/c880892c6b4746bc80717be1f81bf169/embed?ui_theme=dark&dnt=1"> </iframe> </div>

+<p>Der letzte Scan hier wurde nur mit einer <strong>Smartphone-Kamera</strong> erstellt.<br />
+Man erkennt deutlich, dass die Qualität geringer ist, aber angesichts der einfachen Technik finde ich das Ergebnis beeindruckend –<br />
+und es zeigt, wie sehr solche Technologien gerade <strong>demokratisiert</strong> werden.</p>

-<h2 id="Perspective">Perspective</h2>
-<p>What this section is supposed to deliver is the message that I am currently not where I want to be navigating the vast possibilities of CAD. I feel confident enough to approach small repairs around the flat with a new perspective, but I still lack technical expertise when approaching a collection composite parts, having to function together. I still have lots of projects halfdone or half-thought and one major reason is that there is no real critical exchange within my field of study.</p>
-<p>I want more than designing figurines or wearables.
-I want to incorporate 3D printing as a method to extend the abilities of other tools, have mechanical and electrical purposes, be foodsafe and engaging.
-I fell in love with the idea of designing a toy system, inspired by <a href="https://www.kickstarter.com/projects/makeway/makeway-create-intricate-courses-watch-your-marbles-soar">Makeways on Kickstarter</a>, I have already started adding my own parts to their set.</p>
-<p>I dream of my very own 3D printed coffeecup, one that is both foodsafe and dishwasher-surviving. For that, I would have to do quite a bit of material research, but that just makes the idea so much more appealing.
-I would love finding a material composition incorporating waste to stop relying on plastics, or at least on fossile plastics.
-Once in Berlin, I would want to talk to the people at <a href="https://www.kaffeeform.com/en/">Kaffeform</a> producing largely compostable Coffee Cups incorporating a significant amount of old ground espresso, albeit using injection molding for their process.
-The industry selling composite filaments is much more conservative with the percentage of non-plastic additives, because with a nozzle extrusion process there is much more to go wrong.
-Still, I would love to explore that avenue further and think there is a lot to be gained from looking at pellet printers.</p>
-<p>I also credit huge parts of my exploration process into local recycling to the awesome people at <a href="https://preciousplastic.com">Precious Plastic</a>, who I will join over the summer to learn more about their system.</p>
-<p>I find it hard to write anything about CAD without connecting it directly to a manufacturing process.
-And I believe that's a good thing. Always tying a design process to its realization, grounds the process and attaches to it some immediacy.</p>
-<p>For me to become more confident in this process, I am still missing more expertise in organic shapes, so I would be happy to dig more into Blender, an awesome tool that in my mind is far too powerful to dive into it with just youtube lessons.</p>

+<h2 id="Perspektive">Perspektive</h2>
+<p>Was dieser Abschnitt zeigen soll: Ich bin beim Thema <strong>CAD</strong> noch nicht da, wo ich gerne wäre.<br />
+Ich fühle mich sicher genug, um kleine Reparaturen im Alltag anzugehen,<br />
+aber beim <strong>Konstruieren komplexer Bauteilgruppen</strong>, die zusammen funktionieren müssen, fehlt mir noch technisches Know-how.<br />
+Viele meiner Projekte sind halbfertig – einer der Hauptgründe ist der <strong>Mangel an fachlichem Austausch</strong> in meinem Umfeld.</p>
+<p>Ich möchte mehr als nur Figuren oder Wearables gestalten.<br />
+Ich möchte den <strong>3D-Druck als Werkzeugerweiterung</strong> nutzen –<br />
+für mechanische oder elektrische Anwendungen, lebensmittelechte Objekte, oder einfach Dinge, die begeistern.<br />
+Ich liebe die Idee, ein <strong>Baukastensystem</strong> zu entwickeln.<br />
+Inspiriert von <a href="https://www.kickstarter.com/projects/makeway/makeway-create-intricate-courses-watch-your-marbles-soar">Makeways auf Kickstarter</a> habe ich bereits angefangen, eigene Teile zu entwerfen.</p>
+<p>Ein Traum von mir ist eine <strong>eigene 3D-gedruckte Kaffeetasse</strong>, die sowohl <strong>spülmaschinenfest als auch lebensmittelecht</strong> ist.<br />
+Dafür müsste ich viel Materialforschung betreiben – aber genau das macht es spannend.<br />
+Ich möchte ein Material finden, das <strong>Abfälle</strong> einbezieht, um weniger von <strong>fossilen Kunststoffen</strong> abhängig zu sein.<br />
+In Berlin möchte ich mich mit den Leuten von <a href="https://www.kaffeeform.com/de/">Kaffeform</a> austauschen, die <strong>kompostierbare Becher</strong> aus gebrauchten Espressoresten herstellen (wenn auch per Spritzgussverfahren).</p>
+<p>Die Hersteller von <strong>Komposit-Filamenten</strong> sind bei der Beimischung nicht-plastischer Stoffe sehr vorsichtig,<br />
+weil der <strong>Extrusionsprozess</strong> durch Düsen leicht fehleranfällig ist.<br />
+Trotzdem glaube ich, dass gerade in diesem Bereich noch viel Potenzial steckt – besonders mit <strong>Pelletdruckern</strong>.</p>
+<p>Große Teile meiner Auseinandersetzung mit <strong>lokalem Recycling</strong> verdanke ich den großartigen Leuten von <a href="https://preciousplastic.com">Precious Plastic</a>, deren Open-Source-Designs mich sehr inspiriert haben.<br />
+Ich finde es schwer, über CAD zu schreiben, ohne gleichzeitig über den <strong>Herstellungsprozess</strong> zu sprechen –<br />
+und ich halte das für etwas Gutes.<br />
+Design und Umsetzung gehören für mich zusammen.</p>
+<p>Um noch sicherer zu werden, möchte ich mich stärker auf <strong>organische Formen</strong> konzentrieren.<br />
+Deshalb will ich tiefer in <strong>Blender</strong> einsteigen – ein großartiges Tool, das viel zu mächtig ist, um es nur über YouTube zu lernen.</p>

-<p>While learning about 3D Printing, I was most intrigued by the possibility to modify and repair existing products. While there is an amazing community with lots of good and free models around, naturally I came to a point where I did not find what I was looking for readily designed. I realized this is an essential skill for effectively operating not just 3D Printers, but any productive machine really.</p>
-<p>Since youtube was the place I was learning all about 3D Printing, and all the people that I looked up to there were using Fusion 360 as their CAD Program that’s what I got into.
-In hindsight, that was a pretty good choice and I am in love with the abilities parametric design gives me.
-Below you will find some of my designs.
-The process is something that I enjoy a lot and wish to dive into deeper.</p>
-<p>By trial and error, I already learned a lot about designing specifically for 3D Printing, but I often feel that there are many aesthetic considerations in design that I am not familiar with.
-I want to broaden my general ability to design physical objects, which is something I hope to gain during my master’s.</p>

-<h3 id="Interaction_with_real_objects_and_environments">Interaction with real objects and environments</h3>
-<p>In the last few years I have played around with a few smartphone cameras and was always quite sad, that my scans were never quite accurate enough to do cool stuff with them.
-I could not really afford real 3D scanner and had already started cobbling together a raspberry Pi camera with a cheap TOF sensor, which is a simple, but not quite as good replacement for a laser or a lidar sensor, but then Apple came out with the first phones with accessible Lidar sensor.
-Recently, through work at the university I got access to a device with a lidar sensor and started having fun with it.
-See some examples here:</p>

-<p>This last one was scanned with just my smartphone camera. You can see that the quality is notably worse, but considering is was created with just a single, run-of-the-mill smartphone sensor, I think it is still pretty impressive and will certainly do something towards democratizing such technologies and abilities.</p>

+<p>In den letzten Jahren habe ich mit verschiedenen Smartphone-Kameras experimentiert – leider waren meine Scans meist nicht präzise genug, um wirklich etwas damit anzufangen.<br />
+Ein professioneller 3D-Scanner war zu teuer, also bastelte ich mir eine Kombination aus einer <strong>Raspberry-Pi-Kamera</strong> und einem günstigen <strong>TOF-Sensor</strong>.<br />
+Das Setup ist simpel, aber bei weitem nicht so genau wie Laser- oder LiDAR-Sensoren. Dann brachte Apple die ersten Geräte mit <strong>zugänglichem LiDAR</strong> heraus.</p>

+<p>Der letzte Scan hier wurde nur mit einer <strong>Smartphone-Kamera</strong> erstellt.<br />

-<h2 id="Perspective">Perspective</h2>
-<p>What this section is supposed to deliver is the message that I am currently not where I want to be navigating the vast possibilities of CAD. I feel confident enough to approach small repairs around the flat with a new perspective, but I still lack technical expertise when approaching a collection composite parts, having to function together. I still have lots of projects halfdone or half-thought and one major reason is that there is no real critical exchange within my field of study.</p>
-<p>I want more than designing figurines or wearables.
-I want to incorporate 3D printing as a method to extend the abilities of other tools, have mechanical and electrical purposes, be foodsafe and engaging.
-I fell in love with the idea of designing a toy system, inspired by <a href="https://www.kickstarter.com/projects/makeway/makeway-create-intricate-courses-watch-your-marbles-soar">Makeways on Kickstarter</a>, I have already started adding my own parts to their set.</p>
-<p>I dream of my very own 3D printed coffeecup, one that is both foodsafe and dishwasher-surviving. For that, I would have to do quite a bit of material research, but that just makes the idea so much more appealing.
-I would love finding a material composition incorporating waste to stop relying on plastics, or at least on fossile plastics.
-Once in Berlin, I would want to talk to the people at <a href="https://www.kaffeeform.com/en/">Kaffeform</a> producing largely compostable Coffee Cups incorporating a significant amount of old ground espresso, albeit using injection molding for their process.
-The industry selling composite filaments is much more conservative with the percentage of non-plastic additives, because with a nozzle extrusion process there is much more to go wrong.
-Still, I would love to explore that avenue further and think there is a lot to be gained from looking at pellet printers.</p>
-<p>I also credit huge parts of my exploration process into local recycling to the awesome people at <a href="https://preciousplastic.com">Precious Plastic</a>, who I will join over the summer to learn more about their system.</p>
-<p>I find it hard to write anything about CAD without connecting it directly to a manufacturing process.
-And I believe that's a good thing. Always tying a design process to its realization, grounds the process and attaches to it some immediacy.</p>
-<p>For me to become more confident in this process, I am still missing more expertise in organic shapes, so I would be happy to dig more into Blender, an awesome tool that in my mind is far too powerful to dive into it with just youtube lessons.</p>

+<p>Was dieser Abschnitt zeigen soll: Ich bin beim Thema <strong>CAD</strong> noch nicht da, wo ich gerne wäre.<br />
+Ich fühle mich sicher genug, um kleine Reparaturen im Alltag anzugehen,<br />
+aber beim <strong>Konstruieren komplexer Bauteilgruppen</strong>, die zusammen funktionieren müssen, fehlt mir noch technisches Know-how.<br />
+Viele meiner Projekte sind halbfertig – einer der Hauptgründe ist der <strong>Mangel an fachlichem Austausch</strong> in meinem Umfeld.</p>
+<p>Ich möchte mehr als nur Figuren oder Wearables gestalten.<br />
+Ich möchte den <strong>3D-Druck als Werkzeugerweiterung</strong> nutzen –<br />
+für mechanische oder elektrische Anwendungen, lebensmittelechte Objekte, oder einfach Dinge, die begeistern.<br />
+Ich liebe die Idee, ein <strong>Baukastensystem</strong> zu entwickeln.<br />
+Inspiriert von <a href="https://www.kickstarter.com/projects/makeway/makeway-create-intricate-courses-watch-your-marbles-soar">Makeways auf Kickstarter</a> habe ich bereits angefangen, eigene Teile zu entwerfen.</p>
+<p>Ein Traum von mir ist eine <strong>eigene 3D-gedruckte Kaffeetasse</strong>, die sowohl <strong>spülmaschinenfest als auch lebensmittelecht</strong> ist.<br />
+Dafür müsste ich viel Materialforschung betreiben – aber genau das macht es spannend.<br />
+Ich möchte ein Material finden, das <strong>Abfälle</strong> einbezieht, um weniger von <strong>fossilen Kunststoffen</strong> abhängig zu sein.<br />
+In Berlin möchte ich mich mit den Leuten von <a href="https://www.kaffeeform.com/de/">Kaffeform</a> austauschen, die <strong>kompostierbare Becher</strong> aus gebrauchten Espressoresten herstellen (wenn auch per Spritzgussverfahren).</p>
+<p>Die Hersteller von <strong>Komposit-Filamenten</strong> sind bei der Beimischung nicht-plastischer Stoffe sehr vorsichtig,<br />
+weil der <strong>Extrusionsprozess</strong> durch Düsen leicht fehleranfällig ist.<br />
+Trotzdem glaube ich, dass gerade in diesem Bereich noch viel Potenzial steckt – besonders mit <strong>Pelletdruckern</strong>.</p>
+<p>Große Teile meiner Auseinandersetzung mit <strong>lokalem Recycling</strong> verdanke ich den großartigen Leuten von <a href="https://preciousplastic.com">Precious Plastic</a>, deren Open-Source-Designs mich sehr inspiriert haben.<br />
+Ich finde es schwer, über CAD zu schreiben, ohne gleichzeitig über den <strong>Herstellungsprozess</strong> zu sprechen –<br />
+und ich halte das für etwas Gutes.<br />
+Design und Umsetzung gehören für mich zusammen.</p>
+<p>Um noch sicherer zu werden, möchte ich mich stärker auf <strong>organische Formen</strong> konzentrieren.<br />
+Deshalb will ich tiefer in <strong>Blender</strong> einsteigen – ein großartiges Tool, das viel zu mächtig ist, um es nur über YouTube zu lernen.</p>

-<p>As you can see, the design faces some questionable choices, but all mechanics are homemade from the ground up and I learned a lot. I often struggle to enjoy competitive games and think there is potential in a co-dependent game interface. During early testing, we often found that it enforces player communication since already the tutorial is quite hard to beat.
-Due to me being a leftie, perhaps not entirely smart, I gave player one the keyboard arrows to work with and player two the WASD keys and left and right mouse buttons for grappling and shooting. For the game, it has an interesting side effect, in that players are forced not only to interact through the differing information on each player's screen but also have to physically interact and coordinate the controls.</p>
-<p>As you can perhaps see, the ball-rolling navigation is quite hard to use.
-It is a purely physics-based system, where, depending on the materiality of the ball, its weight, and therefore its inertia will drastically change.</p>
-<p>On small screens, the prototype version of the game is virtually impossible to control and several visual bugs within the viewport still obfuscate items when they are too close. Considering that virtually all the mechanics are written from scratch, with a follow-me camera, collision detection, smart moving agents, and a still very wonky-looking grappling gun, I still think it deserves a spot in this portfolio.
-For this project I focused completely on the mechanics of the game, resulting in lots of used prefabs and readymade 3D Objects. Next time, I want to do that myself too.</p>
-<p>I enjoyed my stint into Unity a lot and am looking forward to creating my first VR application and would love to try out some form of mechanics where the user vision is completely obfuscated by VR and they have to carry their eyes as a handheld connected camera so that the players can move around the camera itself with their hands.</p>
+<p>Das Design enthält einige fragwürdige Entscheidungen, aber alle Mechaniken sind <strong>von Grund auf selbst entwickelt</strong>, und ich habe viel dabei gelernt. Ich spiele selten kompetitive Spiele, sehe aber Potenzial in einer <strong>kooperativen, voneinander abhängigen Spielmechanik</strong>. Schon das Tutorial erfordert intensive Spielerkommunikation.</p>
+<p>Als Linkshänder habe ich Spieler eins die Pfeiltasten gegeben und Spieler zwei die WASD-Tasten sowie die linken und rechten Maustasten für Schießen und Greifhaken. Das führt zu einem interessanten Nebeneffekt: Spieler müssen nicht nur über unterschiedliche Informationen auf ihren Bildschirmen kommunizieren, sondern auch ihre Steuerung physisch koordinieren.</p>
+<p>Die <strong>Ball-Navigation</strong> ist ziemlich schwer zu kontrollieren.<br />
+Es handelt sich um ein <strong>rein physikbasiertes System</strong>, bei dem Material, Gewicht und Trägheit der Kugel die Bewegung stark beeinflussen.</p>
+<p>Auf kleinen Bildschirmen ist die Steuerung praktisch unmöglich, und einige visuelle Bugs verdecken Objekte bei zu naher Ansicht. Dennoch, da fast alle Mechaniken von Grund auf programmiert wurden – inklusive Follow-Camera, Kollisionsabfrage, smarten Agenten und einem noch etwas wackeligen Greifhaken – verdient das Projekt einen Platz im Portfolio.</p>
+<p>Für dieses Projekt habe ich mich komplett auf <strong>Mechaniken</strong> konzentriert, weshalb viele fertige Prefabs und 3D-Objekte verwendet wurden. Beim nächsten Mal möchte ich diese auch selbst erstellen.</p>
+<p>Ich habe Unity sehr genossen und freue mich darauf, meine erste <strong>VR-Anwendung</strong> zu entwickeln.<br />
+Ich möchte Mechaniken ausprobieren, bei denen die Sicht des Spielers durch VR komplett blockiert wird und die Augen als <strong>tragbare, verbundene Kamera</strong> bewegt werden, sodass die Spieler die Kamera selbst physisch steuern können.</p>

- <p>Being involved with 3D Printers, there is the issue of sustainability that I am confronted with regularly.
-Most 3D printed parts never get recycled and add to the global waste problem, rather than reducing it.
-The printer most certainly doesn’t care what it is printing, the main problem is the dimensional accuracy and the purity of the material. All of this leads to a huge industry, Germany being especially involved, using loads of virgin plastic.</p>
-<p>What can be done about it?
-We can design our products to last longer, we can also print recycling labels on them so they do not have to get burned after their first life. We can take care to only print functional objects, not just fun toys nobody uses.
-Yet, none of that prevents the use of virgin plastics. If you buy a spool of filament, there are some recycled options, but usually at twice the price at worse quality. No wonder recycled filament fails to convince the masses. It is mostly a fun thing YouTubers can pursue, not a valid commercial process.</p>
+ <p>Als 3D-Druck-Enthusiast sehe ich mich regelmäßig mit dem Thema Nachhaltigkeit konfrontiert.<br />
+Die meisten 3D-gedruckten Teile werden nie recycelt und tragen eher zum globalen Müllproblem bei, als es zu reduzieren.<br />
+Das Problem liegt weniger beim Drucker selbst als bei der <strong>dimensionalen Genauigkeit</strong> und der <strong>Reinheit des Materials</strong>. Dies führt zu einer riesigen Industrie, insbesondere in Deutschland, die enorme Mengen an <strong>Neukunststoff</strong> verbraucht.</p>
+<h3 id="Was_kann_man_tun?">Was kann man tun?</h3>
+<p>Wir können Produkte langlebiger gestalten, Recycling-Labels aufdrucken und nur funktionale Objekte drucken. Dennoch verhindert dies nicht die Nutzung von Neukunststoffen. Recycelter Filament ist oft doppelt so teuer bei schlechterer Qualität – kein Wunder, dass er kaum Verbreitung findet.</p>

-<p>In my opinion, the core problem is the nonexistent economic feasibility of a proper recycling process. Identifying the exact material of a piece of trash is a very hard problem, definitely not solved yet. So why do we mix the plastic up in the first place? There is a general willingness of people to recycle, but the system for it is missing.</p>
-<h1 id="The_Master_Plan">The Master Plan</h1>
-<p>I want to get people to wash and separate their trash for me, which are the most expensive steps in the recycling process. There is a willingness to take the extra step, and even if just my mom collects bottle caps for me, that is more than I can realistically use up.
-This only really works when I am thinking in a local and decentral environment.
-The existing recycling facilities clearly will not be able to provide 200 different containers for 200 different types of plastic.
-Starting the process with clean and sorted materials, like bottle caps (HDPE) or failed prints (PET-G), I start off with an advantage.
-Now I have to take apart the trash into evenly sized particles.

-<p>With these awesome open-source drawings, I was able to cobble together my very own very dangerous plastic shredder.</p>
-<p>After finding some way to drive this massive axis, I feed the beast and hopefully get tiny pretty uniform plastic bits that are ready to begin the cycle of life anew.</p>
-<p>The solution for the motorization was an old and used garden shredder that still had an intact motor and wiring.

+<p>Mit diesen Open-Source-Zeichnungen konnte ich meinen eigenen, sehr gefährlichen Kunststoff-Shredder zusammenbauen.<br />
+Die Motorisierung übernahm ein alter Gartenschredder, der Motor und Verkabelung intakt hatte. Wir schnitten ihn auseinander und befestigten ihn am Shredder.</p>

-<p>After replacing the weak force transmission screw for an industrial coupler, we were ready to try it out. Obviously, there are still security concerns in this prototype, a proper hopper is already being made.</p>
-<p>Nevertheless, we are confident that this shredder will be able to deal with the light sorts of plastic we are thinking of.
-As you can see, I am now able to produce awesome confetti but to do more with the plastic flakes I have to extrude them.</p>
-<h2 id="Meet_the_Filastruder">Meet the Filastruder</h2>
-<p>This is the Filastruder, designed and made by Tim Elmore, in an attempt to create the cheapest viable way to extrude plastic. The biggest cost issue is the tight industrial tolerances in thickness that have to be adhered to. This is in essence what separates good from the bad filament. The industry standard nowadays is at +-0.03mm. Hard to achieve on a DIY setup, but not unheard of. The setup, like any bigger industry equivalent, consists of a motor pressing plastic pellets through a heated screw, extruding molten plastic at the end through a nozzle, and setting the diameter. The leftmost machine is responsible for winding the filament properly onto a spool.</p>
-<p>Here you can see the extrusion process in action.</p>
+<p>Nach Austausch der schwachen Kraftübertragungsschraube gegen einen Industrie-Kuppler waren wir startklar. Sicherheit bleibt ein Thema, ein richtiger Trichter ist in Arbeit.</p>
+<h2 id="Der_Filastruder">Der Filastruder</h2>
+<p>Der <strong>Filastruder</strong>, entworfen von Tim Elmore, bietet eine kostengünstige Möglichkeit, Filament zu extrudieren.<br />
+Die größten Herausforderungen: <strong>präzise Durchmesserkontrolle</strong> ±0,03 mm, sonst schwankt die Qualität.</p>
+<p>Motor presst Kunststoffpellets durch eine beheizte Schraube, am Ende wird durch die Düse extrudiert und der Durchmesser eingestellt. Links wickelt die Maschine das Filament auf eine Spule.</p>

-<p>The Filastruder is controlled by an Arduino and is highly configurable. The laser sensor visible in the video is already working, but I am missing more direct control over the diameter of the filament.</p>
-<p>When it all really comes down to the single variable of the filament diameter responsible for the quality of my recycled project, a simple Machine Learning optimization directly jumps at me: I have a few variables like winder speed, extrusion speed, heat, and cooling intensity. These variables can be optimized on the fly for an exact diameter. This is actually roughly how virgin filament is produced, commercial facilities just manage much faster.</p>
-<p><img src="/assets/images/recycling_variables.png" alt="The variables in an iterative optimization" /></p>
-<p>So far, I am aware of a few companies and academic projects attempting this process, but none of them manage to get either the quality or the price of other products available. Automatization does not just take out jobs away, I think it can also be a helpful tool, for example tackling environmental issues such as this one.</p>
-<p>This project is very dear to my heart and I plan to investigate it further in the form of a master thesis.
-The realization will require many skills I am already picking up or still need to work on within the Design and Computation program.

-<p>While learning about 3D Printing, I was most intrigued by the possibility to modify and repair existing products. While there is an amazing community with lots of good and free models around, naturally I came to a point where I did not find what I was looking for readily designed. I realized this is an essential skill for effectively operating not just 3D Printers, but any productive machine really.</p>
-<p>Since youtube was the place I was learning all about 3D Printing, and all the people that I looked up to there were using Fusion 360 as their CAD Program that’s what I got into.
-In hindsight, that was a pretty good choice and I am in love with the abilities parametric design gives me.
-Below you will find some of my designs.
-The process is something that I enjoy a lot and wish to dive into deeper.</p>
-<p>By trial and error, I already learned a lot about designing specifically for 3D Printing, but I often feel that there are many aesthetic considerations in design that I am not familiar with.
-I want to broaden my general ability to design physical objects, which is something I hope to gain during my master’s.</p>

+<p>Beim Erlernen des 3D-Drucks hat mich vor allem die Möglichkeit fasziniert, bestehende Produkte zu verändern oder zu reparieren.<br />
+Auch wenn es eine großartige Community mit vielen guten und kostenlosen Modellen gibt, bin ich schnell an den Punkt gekommen, an dem ich nicht fand, was ich suchte.<br />
+Mir wurde klar, dass dies eine wesentliche Fähigkeit ist, um nicht nur 3D-Drucker, sondern grundsätzlich jede Art von Produktionsmaschine sinnvoll zu nutzen.</p>
+<p>Da ich alles über 3D-Druck auf YouTube gelernt habe und dort fast alle mit <strong>Fusion 360</strong> arbeiteten, habe ich mich ebenfalls dafür entschieden.<br />
+Rückblickend war das eine sehr gute Wahl – ich habe mich in die Möglichkeiten des <strong>parametrischen Designs</strong> verliebt.<br />
+Unten findest du einige meiner Entwürfe.<br />
+Der Prozess selbst macht mir unglaublich viel Spaß und ich möchte ihn noch weiter vertiefen.</p>
+<p>Durch Ausprobieren habe ich bereits viel darüber gelernt, wie man speziell für den 3D-Druck konstruiert.<br />
+Trotzdem habe ich oft das Gefühl, dass mir ein tieferes Verständnis für <strong>ästhetische Gestaltung</strong> fehlt.<br />
+Ich möchte meine generelle Fähigkeit erweitern, physische Objekte zu entwerfen – etwas, das ich mir im Masterstudium erhoffe.</p>

-<p>Besides coming up with new objects, incorporating the real world is also an interest of mine.</p>
-<h3 id="Interaction_with_real_objects_and_environments">Interaction with real objects and environments</h3>
-<p>In the last few years I have played around with a few smartphone cameras and was always quite sad, that my scans were never quite accurate enough to do cool stuff with them.
-I could not really afford real 3D scanner and had already started cobbling together a raspberry Pi camera with a cheap TOF sensor, which is a simple, but not quite as good replacement for a laser or a lidar sensor, but then Apple came out with the first phones with accessible Lidar sensor.
-Recently, through work at the university I got access to a device with a lidar sensor and started having fun with it.
-See some examples here:</p>

-<p>This last one was scanned with just my smartphone camera. You can see that the quality is notably worse, but considering is was created with just a single, run-of-the-mill smartphone sensor, I think it is still pretty impressive and will certainly do something towards democratizing such technologies and abilities.</p>

+<h3 id="Interaktion_mit_realen_Objekten_und_Umgebungen">Interaktion mit realen Objekten und Umgebungen</h3>
+<p>In den letzten Jahren habe ich mit verschiedenen Smartphone-Kameras experimentiert – leider waren meine Scans meist nicht präzise genug, um wirklich etwas damit anzufangen.<br />
+Ein professioneller 3D-Scanner war zu teuer, also bastelte ich mir eine Kombination aus einer <strong>Raspberry-Pi-Kamera</strong> und einem günstigen <strong>TOF-Sensor</strong>.<br />
+Das Setup ist simpel, aber bei weitem nicht so genau wie Laser- oder LiDAR-Sensoren. Dann brachte Apple die ersten Geräte mit <strong>zugänglichem LiDAR</strong> heraus.</p>
+<p>Durch meine Arbeit an der Universität hatte ich schließlich Zugriff auf ein Gerät mit LiDAR und begann, damit zu experimentieren.<br />
+Ein paar Beispiele siehst du hier:</p>

+<p>Der letzte Scan hier wurde nur mit einer <strong>Smartphone-Kamera</strong> erstellt.<br />
+Man erkennt deutlich, dass die Qualität geringer ist, aber angesichts der einfachen Technik finde ich das Ergebnis beeindruckend –<br />
+und es zeigt, wie sehr solche Technologien gerade <strong>demokratisiert</strong> werden.</p>

-<h2 id="Perspective">Perspective</h2>
-<p>What this section is supposed to deliver is the message that I am currently not where I want to be navigating the vast possibilities of CAD. I feel confident enough to approach small repairs around the flat with a new perspective, but I still lack technical expertise when approaching a collection composite parts, having to function together. I still have lots of projects halfdone or half-thought and one major reason is that there is no real critical exchange within my field of study.</p>
-<p>I want more than designing figurines or wearables.
-I want to incorporate 3D printing as a method to extend the abilities of other tools, have mechanical and electrical purposes, be foodsafe and engaging.
-I fell in love with the idea of designing a toy system, inspired by <a href="https://www.kickstarter.com/projects/makeway/makeway-create-intricate-courses-watch-your-marbles-soar">Makeways on Kickstarter</a>, I have already started adding my own parts to their set.</p>
-<p>I dream of my very own 3D printed coffeecup, one that is both foodsafe and dishwasher-surviving. For that, I would have to do quite a bit of material research, but that just makes the idea so much more appealing.
-I would love finding a material composition incorporating waste to stop relying on plastics, or at least on fossile plastics.
-Once in Berlin, I would want to talk to the people at <a href="https://www.kaffeeform.com/en/">Kaffeform</a> producing largely compostable Coffee Cups incorporating a significant amount of old ground espresso, albeit using injection molding for their process.
-The industry selling composite filaments is much more conservative with the percentage of non-plastic additives, because with a nozzle extrusion process there is much more to go wrong.
-Still, I would love to explore that avenue further and think there is a lot to be gained from looking at pellet printers.</p>
-<p>I also credit huge parts of my exploration process into local recycling to the awesome people at <a href="https://preciousplastic.com">Precious Plastic</a>, who I will join over the summer to learn more about their system.</p>
-<p>I find it hard to write anything about CAD without connecting it directly to a manufacturing process.
-And I believe that's a good thing. Always tying a design process to its realization, grounds the process and attaches to it some immediacy.</p>
-<p>For me to become more confident in this process, I am still missing more expertise in organic shapes, so I would be happy to dig more into Blender, an awesome tool that in my mind is far too powerful to dive into it with just youtube lessons.</p>

+<h2 id="Perspektive">Perspektive</h2>
+<p>Was dieser Abschnitt zeigen soll: Ich bin beim Thema <strong>CAD</strong> noch nicht da, wo ich gerne wäre.<br />
+Ich fühle mich sicher genug, um kleine Reparaturen im Alltag anzugehen,<br />
+aber beim <strong>Konstruieren komplexer Bauteilgruppen</strong>, die zusammen funktionieren müssen, fehlt mir noch technisches Know-how.<br />
+Viele meiner Projekte sind halbfertig – einer der Hauptgründe ist der <strong>Mangel an fachlichem Austausch</strong> in meinem Umfeld.</p>
+<p>Ich möchte mehr als nur Figuren oder Wearables gestalten.<br />
+Ich möchte den <strong>3D-Druck als Werkzeugerweiterung</strong> nutzen –<br />
+für mechanische oder elektrische Anwendungen, lebensmittelechte Objekte, oder einfach Dinge, die begeistern.<br />
+Ich liebe die Idee, ein <strong>Baukastensystem</strong> zu entwickeln.<br />
+Inspiriert von <a href="https://www.kickstarter.com/projects/makeway/makeway-create-intricate-courses-watch-your-marbles-soar">Makeways auf Kickstarter</a> habe ich bereits angefangen, eigene Teile zu entwerfen.</p>
+<p>Ein Traum von mir ist eine <strong>eigene 3D-gedruckte Kaffeetasse</strong>, die sowohl <strong>spülmaschinenfest als auch lebensmittelecht</strong> ist.<br />
+Dafür müsste ich viel Materialforschung betreiben – aber genau das macht es spannend.<br />
+Ich möchte ein Material finden, das <strong>Abfälle</strong> einbezieht, um weniger von <strong>fossilen Kunststoffen</strong> abhängig zu sein.<br />
+In Berlin möchte ich mich mit den Leuten von <a href="https://www.kaffeeform.com/de/">Kaffeform</a> austauschen, die <strong>kompostierbare Becher</strong> aus gebrauchten Espressoresten herstellen (wenn auch per Spritzgussverfahren).</p>
+<p>Die Hersteller von <strong>Komposit-Filamenten</strong> sind bei der Beimischung nicht-plastischer Stoffe sehr vorsichtig,<br />
+weil der <strong>Extrusionsprozess</strong> durch Düsen leicht fehleranfällig ist.<br />
+Trotzdem glaube ich, dass gerade in diesem Bereich noch viel Potenzial steckt – besonders mit <strong>Pelletdruckern</strong>.</p>
+<p>Große Teile meiner Auseinandersetzung mit <strong>lokalem Recycling</strong> verdanke ich den großartigen Leuten von <a href="https://preciousplastic.com">Precious Plastic</a>, deren Open-Source-Designs mich sehr inspiriert haben.<br />
+Ich finde es schwer, über CAD zu schreiben, ohne gleichzeitig über den <strong>Herstellungsprozess</strong> zu sprechen –<br />
+und ich halte das für etwas Gutes.<br />
+Design und Umsetzung gehören für mich zusammen.</p>
+<p>Um noch sicherer zu werden, möchte ich mich stärker auf <strong>organische Formen</strong> konzentrieren.<br />
+Deshalb will ich tiefer in <strong>Blender</strong> einsteigen – ein großartiges Tool, das viel zu mächtig ist, um es nur über YouTube zu lernen.</p>

- <p>Being involved with 3D Printers, there is the issue of sustainability that I am confronted with regularly.
-Most 3D printed parts never get recycled and add to the global waste problem, rather than reducing it.
-The printer most certainly doesn’t care what it is printing, the main problem is the dimensional accuracy and the purity of the material. All of this leads to a huge industry, Germany being especially involved, using loads of virgin plastic.</p>
-<p>What can be done about it?
-We can design our products to last longer, we can also print recycling labels on them so they do not have to get burned after their first life. We can take care to only print functional objects, not just fun toys nobody uses.
-Yet, none of that prevents the use of virgin plastics. If you buy a spool of filament, there are some recycled options, but usually at twice the price at worse quality. No wonder recycled filament fails to convince the masses. It is mostly a fun thing YouTubers can pursue, not a valid commercial process.</p>
+ <p>Als 3D-Druck-Enthusiast sehe ich mich regelmäßig mit dem Thema Nachhaltigkeit konfrontiert.<br />
+Die meisten 3D-gedruckten Teile werden nie recycelt und tragen eher zum globalen Müllproblem bei, als es zu reduzieren.<br />
+Das Problem liegt weniger beim Drucker selbst als bei der <strong>dimensionalen Genauigkeit</strong> und der <strong>Reinheit des Materials</strong>. Dies führt zu einer riesigen Industrie, insbesondere in Deutschland, die enorme Mengen an <strong>Neukunststoff</strong> verbraucht.</p>
+<h3 id="Was_kann_man_tun?">Was kann man tun?</h3>
+<p>Wir können Produkte langlebiger gestalten, Recycling-Labels aufdrucken und nur funktionale Objekte drucken. Dennoch verhindert dies nicht die Nutzung von Neukunststoffen. Recycelter Filament ist oft doppelt so teuer bei schlechterer Qualität – kein Wunder, dass er kaum Verbreitung findet.</p>

-<p>In my opinion, the core problem is the nonexistent economic feasibility of a proper recycling process. Identifying the exact material of a piece of trash is a very hard problem, definitely not solved yet. So why do we mix the plastic up in the first place? There is a general willingness of people to recycle, but the system for it is missing.</p>
-<h1 id="The_Master_Plan">The Master Plan</h1>
-<p>I want to get people to wash and separate their trash for me, which are the most expensive steps in the recycling process. There is a willingness to take the extra step, and even if just my mom collects bottle caps for me, that is more than I can realistically use up.
-This only really works when I am thinking in a local and decentral environment.
-The existing recycling facilities clearly will not be able to provide 200 different containers for 200 different types of plastic.
-Starting the process with clean and sorted materials, like bottle caps (HDPE) or failed prints (PET-G), I start off with an advantage.
-Now I have to take apart the trash into evenly sized particles.
-Meet:</p>
-<h2 id="The_Shredder">The Shredder</h2>
-<p>We built the Precious Plastic Shredder!</p>

-<p>With these awesome open-source drawings, I was able to cobble together my very own very dangerous plastic shredder.</p>
-<p>After finding some way to drive this massive axis, I feed the beast and hopefully get tiny pretty uniform plastic bits that are ready to begin the cycle of life anew.</p>
-<p>The solution for the motorization was an old and used garden shredder that still had an intact motor and wiring.
-We cut it in half and attached it to the shredder box.</p>
+<p>Das Kernproblem ist die <strong>fehlende wirtschaftliche Machbarkeit</strong> eines echten Recyclings. Das exakte Identifizieren von Kunststoffarten ist extrem schwierig und noch ungelöst. Es gibt Bereitschaft zu recyceln, aber das System fehlt.</p>
+<h1 id="Der_Masterplan">Der Masterplan</h1>
+<p>Ich möchte Menschen motivieren, ihren Müll <strong>zu waschen und zu sortieren</strong>, die teuersten Schritte im Recyclingprozess. Selbst kleine Beiträge, wie meine Mutter, die Flaschendeckel sammelt, sind wertvoll.<br />
+Dies funktioniert nur in einem <strong>lokalen, dezentralen Umfeld</strong>. Existierende Recyclinganlagen können nicht 200 verschiedene Kunststoffarten trennen.</p>
+<p>Mit sauberem, sortiertem Material – etwa Flaschendeckel (HDPE) oder fehlerhafte Drucke (PET-G) – starte ich bereits im Vorteil. Jetzt müssen die Teile noch in <strong>gleichmäßige Partikel</strong> zerkleinert werden.</p>

+<p>Mit diesen Open-Source-Zeichnungen konnte ich meinen eigenen, sehr gefährlichen Kunststoff-Shredder zusammenbauen.<br />
+Die Motorisierung übernahm ein alter Gartenschredder, der Motor und Verkabelung intakt hatte. Wir schnitten ihn auseinander und befestigten ihn am Shredder.</p>

-<p>After replacing the weak force transmission screw for an industrial coupler, we were ready to try it out. Obviously, there are still security concerns in this prototype, a proper hopper is already being made.</p>
-<p>Nevertheless, we are confident that this shredder will be able to deal with the light sorts of plastic we are thinking of.
-As you can see, I am now able to produce awesome confetti but to do more with the plastic flakes I have to extrude them.</p>
-<h2 id="Meet_the_Filastruder">Meet the Filastruder</h2>
-<p>This is the Filastruder, designed and made by Tim Elmore, in an attempt to create the cheapest viable way to extrude plastic. The biggest cost issue is the tight industrial tolerances in thickness that have to be adhered to. This is in essence what separates good from the bad filament. The industry standard nowadays is at +-0.03mm. Hard to achieve on a DIY setup, but not unheard of. The setup, like any bigger industry equivalent, consists of a motor pressing plastic pellets through a heated screw, extruding molten plastic at the end through a nozzle, and setting the diameter. The leftmost machine is responsible for winding the filament properly onto a spool.</p>
-<p>Here you can see the extrusion process in action.</p>
+<p>Nach Austausch der schwachen Kraftübertragungsschraube gegen einen Industrie-Kuppler waren wir startklar. Sicherheit bleibt ein Thema, ein richtiger Trichter ist in Arbeit.</p>
+<h2 id="Der_Filastruder">Der Filastruder</h2>
+<p>Der <strong>Filastruder</strong>, entworfen von Tim Elmore, bietet eine kostengünstige Möglichkeit, Filament zu extrudieren.<br />
+Die größten Herausforderungen: <strong>präzise Durchmesserkontrolle</strong> ±0,03 mm, sonst schwankt die Qualität.</p>
+<p>Motor presst Kunststoffpellets durch eine beheizte Schraube, am Ende wird durch die Düse extrudiert und der Durchmesser eingestellt. Links wickelt die Maschine das Filament auf eine Spule.</p>

-<p>The Filastruder is controlled by an Arduino and is highly configurable. The laser sensor visible in the video is already working, but I am missing more direct control over the diameter of the filament.</p>
-<p>When it all really comes down to the single variable of the filament diameter responsible for the quality of my recycled project, a simple Machine Learning optimization directly jumps at me: I have a few variables like winder speed, extrusion speed, heat, and cooling intensity. These variables can be optimized on the fly for an exact diameter. This is actually roughly how virgin filament is produced, commercial facilities just manage much faster.</p>
-<p><img src="/assets/images/recycling_variables.png" alt="The variables in an iterative optimization" /></p>
-<p>So far, I am aware of a few companies and academic projects attempting this process, but none of them manage to get either the quality or the price of other products available. Automatization does not just take out jobs away, I think it can also be a helpful tool, for example tackling environmental issues such as this one.</p>
-<p>This project is very dear to my heart and I plan to investigate it further in the form of a master thesis.
-The realization will require many skills I am already picking up or still need to work on within the Design and Computation program.

-<p>Starting out, I found it fascinating, how just 4 rather simple ingredients, malt, hops, water and yeast, can form such an incredible range of taste experiences.

-<p>Why do I present such an unrelated non-academic hobby here? I simply do not regard it as unrelated, experimenting and optimizing a process and a workflow, creating optimal conditions for the yeast to do its job feels very similar to approaching a coding project.
-Yeast and what it does fascinates me. Every time I open the latch to release some pressure on the Tank I think of the awesome symbiotic relationships yeast has with humans and how many different strains live there together to create a unique, yet tailored flavor. Several ideas are floating around of changing the brewing process by capturing the created carbon dioxide and using it productively. I could see a car tire being filled with my beer gas, or an algae farm munching away on my CO2 byproducts. Within a closed-loop pressurized system, such ideas actually become realizable and I would love to explore them further.</p>

+<p>Ich liebe es zu veranstalten, ich liebe es, in der Küche zu experimentieren. Mit Homebrews zu starten, war für mich eine natürliche Entscheidung, und während der ersten Covid-19-Welle habe ich den kompletten Heimbräuerweg mit Flaschenfermentation und kleinen Chargen eingeschlagen, später habe ich mein Setup auf 50-Liter-Chargen mit Drucktank-System erweitert.</p>
+<p>Zu Beginn war ich fasziniert, wie aus nur <strong>vier einfachen Zutaten</strong> – Malz, Hopfen, Wasser und Hefe – ein so unglaubliches Spektrum an Geschmackserlebnissen entstehen kann. Es war und ist immer noch ein <strong>tremendales Lernprojekt</strong>, bei dem man langsam akzeptieren muss, dass man den Prozess nicht vollständig kontrollieren kann, und gleichzeitig Raum für Kreativität findet.</p>
+<p>Warum präsentiere ich dieses scheinbar nicht-akademische Hobby hier? Ich sehe es nicht als irrelevant an: <strong>Experimentieren und Optimieren eines Prozesses und Workflows</strong>, optimale Bedingungen für die Hefe zu schaffen, fühlt sich dem Ansatz eines Programmierprojekts sehr ähnlich an.</p>
+<p>Hefe und ihre Wirkung faszinieren mich. Jedes Mal, wenn ich den Verschluss öffne, um etwas Druck aus dem Tank abzulassen, denke ich an die erstaunlichen symbiotischen Beziehungen der Hefe mit Menschen und wie viele verschiedene Stämme zusammenleben, um einen einzigartigen, maßgeschneiderten Geschmack zu erzeugen.<br />
+Es gibt einige Ideen, den Brauprozess zu verändern, indem das erzeugte CO₂ aufgefangen und produktiv genutzt wird – z. B. ein Autoreifen gefüllt mit Biergas oder eine Algenfarm, die das CO₂ aufnimmt. Innerhalb eines <strong>geschlossenen, druckbeaufschlagten Systems</strong> werden solche Ideen tatsächlich realisierbar, und ich möchte sie weiter erforschen.</p>
+<p>Ich bin noch kein Experte für Algen, aber mit Hefe komme ich klar, und ich glaube, dass sie koexistieren und einen nachhaltigeren Produktionszyklus schaffen können.<br />
+Die australische Brauerei Young Henrys integriert Algen bereits in ihren industriellen Prozess: <a href="https://younghenrys.com/algae">The Algae project</a></p>
+<p>Solche Ideen kommen nicht von selbst in die Industrie: Ich glaube, dass Kunst und die experimentelle Entdeckung neuer Techniken dasselbe sind. <strong>Gutes, erfinderisches Design</strong> kann die Gesellschaft verbessern und Schritte in Richtung Nachhaltigkeit gehen. Ich möchte daran teilhaben und neue Wege finden, Hefe in anderen Designkontexten einzusetzen: ob in einem geschlossenen Kreislaufsystem, zum Berechnen von Dingen oder einfach, um mein nächstes Bier mit der perfekten Spritzigkeit zu brauen.</p>

I want to be part of that and would love to find new ways of using yeast in other design contexts: See whether I can make them work in a closed circular system, make them calculate things for me, or simply making my next beer taste awesome with just the right amount of fizz.</p>

+<p>Ich liebe es zu veranstalten, ich liebe es, in der Küche zu experimentieren. Mit Homebrews zu starten, war für mich eine natürliche Entscheidung, und während der ersten Covid-19-Welle habe ich den kompletten Heimbräuerweg mit Flaschenfermentation und kleinen Chargen eingeschlagen, später habe ich mein Setup auf 50-Liter-Chargen mit Drucktank-System erweitert.</p>
+<p>Zu Beginn war ich fasziniert, wie aus nur <strong>vier einfachen Zutaten</strong> – Malz, Hopfen, Wasser und Hefe – ein so unglaubliches Spektrum an Geschmackserlebnissen entstehen kann. Es war und ist immer noch ein <strong>tremendales Lernprojekt</strong>, bei dem man langsam akzeptieren muss, dass man den Prozess nicht vollständig kontrollieren kann, und gleichzeitig Raum für Kreativität findet.</p>
+<p>Warum präsentiere ich dieses scheinbar nicht-akademische Hobby hier? Ich sehe es nicht als irrelevant an: <strong>Experimentieren und Optimieren eines Prozesses und Workflows</strong>, optimale Bedingungen für die Hefe zu schaffen, fühlt sich dem Ansatz eines Programmierprojekts sehr ähnlich an.</p>
+<p>Hefe und ihre Wirkung faszinieren mich. Jedes Mal, wenn ich den Verschluss öffne, um etwas Druck aus dem Tank abzulassen, denke ich an die erstaunlichen symbiotischen Beziehungen der Hefe mit Menschen und wie viele verschiedene Stämme zusammenleben, um einen einzigartigen, maßgeschneiderten Geschmack zu erzeugen.<br />
+Es gibt einige Ideen, den Brauprozess zu verändern, indem das erzeugte CO₂ aufgefangen und produktiv genutzt wird – z. B. ein Autoreifen gefüllt mit Biergas oder eine Algenfarm, die das CO₂ aufnimmt. Innerhalb eines <strong>geschlossenen, druckbeaufschlagten Systems</strong> werden solche Ideen tatsächlich realisierbar, und ich möchte sie weiter erforschen.</p>
+<p>Ich bin noch kein Experte für Algen, aber mit Hefe komme ich klar, und ich glaube, dass sie koexistieren und einen nachhaltigeren Produktionszyklus schaffen können.<br />
+Die australische Brauerei Young Henrys integriert Algen bereits in ihren industriellen Prozess: <a href="https://younghenrys.com/algae">The Algae project</a></p>
+<p>Solche Ideen kommen nicht von selbst in die Industrie: Ich glaube, dass Kunst und die experimentelle Entdeckung neuer Techniken dasselbe sind. <strong>Gutes, erfinderisches Design</strong> kann die Gesellschaft verbessern und Schritte in Richtung Nachhaltigkeit gehen. Ich möchte daran teilhaben und neue Wege finden, Hefe in anderen Designkontexten einzusetzen: ob in einem geschlossenen Kreislaufsystem, zum Berechnen von Dingen oder einfach, um mein nächstes Bier mit der perfekten Spritzigkeit zu brauen.</p>

- <p>Being involved with 3D Printers, there is the issue of sustainability that I am confronted with regularly.
-Most 3D printed parts never get recycled and add to the global waste problem, rather than reducing it.
-The printer most certainly doesn’t care what it is printing, the main problem is the dimensional accuracy and the purity of the material. All of this leads to a huge industry, Germany being especially involved, using loads of virgin plastic.</p>
-<p>What can be done about it?
-We can design our products to last longer, we can also print recycling labels on them so they do not have to get burned after their first life. We can take care to only print functional objects, not just fun toys nobody uses.
-Yet, none of that prevents the use of virgin plastics. If you buy a spool of filament, there are some recycled options, but usually at twice the price at worse quality. No wonder recycled filament fails to convince the masses. It is mostly a fun thing YouTubers can pursue, not a valid commercial process.</p>
+ <p>Als 3D-Druck-Enthusiast sehe ich mich regelmäßig mit dem Thema Nachhaltigkeit konfrontiert.<br />
+Die meisten 3D-gedruckten Teile werden nie recycelt und tragen eher zum globalen Müllproblem bei, als es zu reduzieren.<br />
+Das Problem liegt weniger beim Drucker selbst als bei der <strong>dimensionalen Genauigkeit</strong> und der <strong>Reinheit des Materials</strong>. Dies führt zu einer riesigen Industrie, insbesondere in Deutschland, die enorme Mengen an <strong>Neukunststoff</strong> verbraucht.</p>
+<h3 id="Was_kann_man_tun?">Was kann man tun?</h3>

-<p>In my opinion, the core problem is the nonexistent economic feasibility of a proper recycling process. Identifying the exact material of a piece of trash is a very hard problem, definitely not solved yet. So why do we mix the plastic up in the first place? There is a general willingness of people to recycle, but the system for it is missing.</p>
-<h1 id="The_Master_Plan">The Master Plan</h1>
-<p>I want to get people to wash and separate their trash for me, which are the most expensive steps in the recycling process. There is a willingness to take the extra step, and even if just my mom collects bottle caps for me, that is more than I can realistically use up.
-This only really works when I am thinking in a local and decentral environment.
-The existing recycling facilities clearly will not be able to provide 200 different containers for 200 different types of plastic.
-Starting the process with clean and sorted materials, like bottle caps (HDPE) or failed prints (PET-G), I start off with an advantage.
-Now I have to take apart the trash into evenly sized particles.

-<p>After replacing the weak force transmission screw for an industrial coupler, we were ready to try it out. Obviously, there are still security concerns in this prototype, a proper hopper is already being made.</p>
-<p>Nevertheless, we are confident that this shredder will be able to deal with the light sorts of plastic we are thinking of.
-As you can see, I am now able to produce awesome confetti but to do more with the plastic flakes I have to extrude them.</p>
-<h2 id="Meet_the_Filastruder">Meet the Filastruder</h2>
-<p>This is the Filastruder, designed and made by Tim Elmore, in an attempt to create the cheapest viable way to extrude plastic. The biggest cost issue is the tight industrial tolerances in thickness that have to be adhered to. This is in essence what separates good from the bad filament. The industry standard nowadays is at +-0.03mm. Hard to achieve on a DIY setup, but not unheard of. The setup, like any bigger industry equivalent, consists of a motor pressing plastic pellets through a heated screw, extruding molten plastic at the end through a nozzle, and setting the diameter. The leftmost machine is responsible for winding the filament properly onto a spool.</p>

+Die größten Herausforderungen: <strong>präzise Durchmesserkontrolle</strong> ±0,03 mm, sonst schwankt die Qualität.</p>
+<p>Motor presst Kunststoffpellets durch eine beheizte Schraube, am Ende wird durch die Düse extrudiert und der Durchmesser eingestellt. Links wickelt die Maschine das Filament auf eine Spule.</p>

-<p>The Filastruder is controlled by an Arduino and is highly configurable. The laser sensor visible in the video is already working, but I am missing more direct control over the diameter of the filament.</p>
-<p>When it all really comes down to the single variable of the filament diameter responsible for the quality of my recycled project, a simple Machine Learning optimization directly jumps at me: I have a few variables like winder speed, extrusion speed, heat, and cooling intensity. These variables can be optimized on the fly for an exact diameter. This is actually roughly how virgin filament is produced, commercial facilities just manage much faster.</p>
-<p><img src="/assets/images/recycling_variables.png" alt="The variables in an iterative optimization" /></p>
-<p>So far, I am aware of a few companies and academic projects attempting this process, but none of them manage to get either the quality or the price of other products available. Automatization does not just take out jobs away, I think it can also be a helpful tool, for example tackling environmental issues such as this one.</p>
-<p>This project is very dear to my heart and I plan to investigate it further in the form of a master thesis.
-The realization will require many skills I am already picking up or still need to work on within the Design and Computation program.

-<h3 id="Interaction_with_real_objects_and_environments">Interaction with real objects and environments</h3>
-<p>In the last few years I have played around with a few smartphone cameras and was always quite sad, that my scans were never quite accurate enough to do cool stuff with them.
-I could not really afford real 3D scanner and had already started cobbling together a raspberry Pi camera with a cheap TOF sensor, which is a simple, but not quite as good replacement for a laser or a lidar sensor, but then Apple came out with the first phones with accessible Lidar sensor.
-Recently, through work at the university I got access to a device with a lidar sensor and started having fun with it.
-See some examples here:</p>

-<p>This last one was scanned with just my smartphone camera. You can see that the quality is notably worse, but considering is was created with just a single, run-of-the-mill smartphone sensor, I think it is still pretty impressive and will certainly do something towards democratizing such technologies and abilities.</p>

+<p>In den letzten Jahren habe ich mit verschiedenen Smartphone-Kameras experimentiert – leider waren meine Scans meist nicht präzise genug, um wirklich etwas damit anzufangen.<br />
+Ein professioneller 3D-Scanner war zu teuer, also bastelte ich mir eine Kombination aus einer <strong>Raspberry-Pi-Kamera</strong> und einem günstigen <strong>TOF-Sensor</strong>.<br />
+Das Setup ist simpel, aber bei weitem nicht so genau wie Laser- oder LiDAR-Sensoren. Dann brachte Apple die ersten Geräte mit <strong>zugänglichem LiDAR</strong> heraus.</p>
+<p>Durch meine Arbeit an der Universität hatte ich schließlich Zugriff auf ein Gerät mit LiDAR und begann, damit zu experimentieren.<br />

-<h2 id="Perspective">Perspective</h2>
-<p>What this section is supposed to deliver is the message that I am currently not where I want to be navigating the vast possibilities of CAD. I feel confident enough to approach small repairs around the flat with a new perspective, but I still lack technical expertise when approaching a collection composite parts, having to function together. I still have lots of projects halfdone or half-thought and one major reason is that there is no real critical exchange within my field of study.</p>
-<p>I want more than designing figurines or wearables.
-I want to incorporate 3D printing as a method to extend the abilities of other tools, have mechanical and electrical purposes, be foodsafe and engaging.
-I fell in love with the idea of designing a toy system, inspired by <a href="https://www.kickstarter.com/projects/makeway/makeway-create-intricate-courses-watch-your-marbles-soar">Makeways on Kickstarter</a>, I have already started adding my own parts to their set.</p>
-<p>I dream of my very own 3D printed coffeecup, one that is both foodsafe and dishwasher-surviving. For that, I would have to do quite a bit of material research, but that just makes the idea so much more appealing.
-I would love finding a material composition incorporating waste to stop relying on plastics, or at least on fossile plastics.
-Once in Berlin, I would want to talk to the people at <a href="https://www.kaffeeform.com/en/">Kaffeform</a> producing largely compostable Coffee Cups incorporating a significant amount of old ground espresso, albeit using injection molding for their process.
-The industry selling composite filaments is much more conservative with the percentage of non-plastic additives, because with a nozzle extrusion process there is much more to go wrong.
-Still, I would love to explore that avenue further and think there is a lot to be gained from looking at pellet printers.</p>
-<p>I also credit huge parts of my exploration process into local recycling to the awesome people at <a href="https://preciousplastic.com">Precious Plastic</a>, who I will join over the summer to learn more about their system.</p>
-<p>I find it hard to write anything about CAD without connecting it directly to a manufacturing process.
-And I believe that's a good thing. Always tying a design process to its realization, grounds the process and attaches to it some immediacy.</p>
-<p>For me to become more confident in this process, I am still missing more expertise in organic shapes, so I would be happy to dig more into Blender, an awesome tool that in my mind is far too powerful to dive into it with just youtube lessons.</p>

+<p>Was dieser Abschnitt zeigen soll: Ich bin beim Thema <strong>CAD</strong> noch nicht da, wo ich gerne wäre.<br />
+Ich fühle mich sicher genug, um kleine Reparaturen im Alltag anzugehen,<br />
+aber beim <strong>Konstruieren komplexer Bauteilgruppen</strong>, die zusammen funktionieren müssen, fehlt mir noch technisches Know-how.<br />
+Viele meiner Projekte sind halbfertig – einer der Hauptgründe ist der <strong>Mangel an fachlichem Austausch</strong> in meinem Umfeld.</p>
+<p>Ich möchte mehr als nur Figuren oder Wearables gestalten.<br />
+Ich möchte den <strong>3D-Druck als Werkzeugerweiterung</strong> nutzen –<br />
+für mechanische oder elektrische Anwendungen, lebensmittelechte Objekte, oder einfach Dinge, die begeistern.<br />
+Ich liebe die Idee, ein <strong>Baukastensystem</strong> zu entwickeln.<br />
+Inspiriert von <a href="https://www.kickstarter.com/projects/makeway/makeway-create-intricate-courses-watch-your-marbles-soar">Makeways auf Kickstarter</a> habe ich bereits angefangen, eigene Teile zu entwerfen.</p>
+<p>Ein Traum von mir ist eine <strong>eigene 3D-gedruckte Kaffeetasse</strong>, die sowohl <strong>spülmaschinenfest als auch lebensmittelecht</strong> ist.<br />
+Dafür müsste ich viel Materialforschung betreiben – aber genau das macht es spannend.<br />
+Ich möchte ein Material finden, das <strong>Abfälle</strong> einbezieht, um weniger von <strong>fossilen Kunststoffen</strong> abhängig zu sein.<br />
+In Berlin möchte ich mich mit den Leuten von <a href="https://www.kaffeeform.com/de/">Kaffeform</a> austauschen, die <strong>kompostierbare Becher</strong> aus gebrauchten Espressoresten herstellen (wenn auch per Spritzgussverfahren).</p>
+<p>Die Hersteller von <strong>Komposit-Filamenten</strong> sind bei der Beimischung nicht-plastischer Stoffe sehr vorsichtig,<br />
+weil der <strong>Extrusionsprozess</strong> durch Düsen leicht fehleranfällig ist.<br />
+Trotzdem glaube ich, dass gerade in diesem Bereich noch viel Potenzial steckt – besonders mit <strong>Pelletdruckern</strong>.</p>
+<p>Große Teile meiner Auseinandersetzung mit <strong>lokalem Recycling</strong> verdanke ich den großartigen Leuten von <a href="https://preciousplastic.com">Precious Plastic</a>, deren Open-Source-Designs mich sehr inspiriert haben.<br />
+Ich finde es schwer, über CAD zu schreiben, ohne gleichzeitig über den <strong>Herstellungsprozess</strong> zu sprechen –<br />
+und ich halte das für etwas Gutes.<br />
+Design und Umsetzung gehören für mich zusammen.</p>
+<p>Um noch sicherer zu werden, möchte ich mich stärker auf <strong>organische Formen</strong> konzentrieren.<br />
+Deshalb will ich tiefer in <strong>Blender</strong> einsteigen – ein großartiges Tool, das viel zu mächtig ist, um es nur über YouTube zu lernen.</p>

-<p>Access to Electricity is a basic human right. At first, that may seem over the top, but if one stops to think what all the little tasks that electricity can indirectly handle for us (lightning, laundry, cooking, freezing, heating, entertaining…) would consume in time and effort if we had to perform them manually, this idea becomes very clear. There are globally around 1 billion people without tier 2 access to electricity.</p>

-<p><img src="/assets/images/electricity_tiers.png" alt="The electricity tiers defined by the UN" /></p>
-<p>People only know the intensity of labor that goes into everything when there is no electricity. And it is not even only about convenience, electricity is an enormous lifesaver in any number of scenarios, think just of hospitals or mobile phone networks that would be rendered completely useless without it. So we can easily agree on a need, a demand for electricity globally, for every person. But what about the supply? Why is there 1 billion undersupplied?
-The Answer: missing profitability. It would be a charity project to supply every last person on earth, not a profitable one. And while charitable projects are noble and should be pursued, the reality within capitalism shows that this is not the way it is going to happen.
-But what if we could come up with technology, or rather, a communal structure, that enables us to supply profitably, and still adapt to both, the difficult external factors (weather issues, remoteness, altitude, etc.) and the smaller purses of the undersupplied?</p>

+<p>Zugang zu Elektrizität ist ein grundlegendes Menschenrecht. Das mag zunächst übertrieben klingen, doch wenn man bedenkt, wie viele kleine Aufgaben der Strom uns indirekt abnimmt – Licht, Wäsche, Kochen, Kühlen, Heizen, Unterhaltung – wird schnell klar, wie viel Zeit und Aufwand ohne Elektrizität nötig wäre. Weltweit leben etwa <strong>eine Milliarde Menschen</strong> ohne Zugang zu Strom auf dem sogenannten Tier-2-Level.</p>

+Warum also sind immer noch so viele Menschen unterversorgt?<br />
+<strong>Die Antwort: fehlende Rentabilität.</strong> Es wäre ein wohltätiges, aber kein profitables Projekt, jede Person auf der Welt zu versorgen. Doch was, wenn wir eine Struktur finden könnten, die <strong>wirtschaftlich tragfähig</strong> ist und sich gleichzeitig an schwierige Bedingungen (Wetter, Abgeschiedenheit, Höhenlage) sowie an kleinere Einkommen anpassen kann?</p>

-<p>In an environment reliant on hydro-energy and solar (diesel transport is unreliable due to snowed-in mountain roads), over 6 months of snowy winter, frequent snowstorms, and temperatures of up to -35°C, securing the grid is hard.</p>
-<p>Our way to tackle the issue was to reject the in the western society very established notion of electricity as a homogenous product with centralized production and instead researched the possibilities of a predictive, self-correcting, and decentral grid.</p>
-<p>By prioritizing energy usage cases, instead of a full blackout during a storm, essential functions like radio towers and hospitals could be partially powered and maybe stay functioning. The binarity of either having electricity or not would be replaced by assigned quantities and timeslots, in a collective effort to be mindful and distribute the electricity necessity-based.
-The ultimate vision was a live predictive electricity market, where people could even earn money by selling their allotted, but not needed electricity.
-To gauge feasibility, I conducted several psychological acceptance studies and collected data on local electricity demands.
-I simulated a typical day of electricity demand in the Key monastery and the surrounding villages and mapped out the potential to install cost-efficient smart microgrid controllers enabling such an accurate and predictive behavior.
-The smart grid operator boxes available here in Germany cost several hundred, with installation several thousand Euros, not a feasible solution for the Indian population. Instead, we wanted to use Raspberry Pi's, which are interconnected through ethernet cables or local mesh networking.</p>

-<h2 id="Data_Collection">Data Collection</h2>
-<p>Building a questionnaire and visiting public schools during their English Classes, I had the chance to speak to a range of teenagers, answering questions about the state of electricity in their homes, generating more data than I could have accomplished running from door to door without any skills speaking local dialects. The questionnaire was as scientific as I could make it in such a situation and geared towards finding the type and number of electric devices in the homes and estimating typical usage scenarios.</p>
-<p>With a total of 145 participants from more than 6 different schools and roughly 4 different districts, all located in the Indian part of the Himalayas, the findings are as follows:</p>
-<p>The participants range from 11 to 53 years, with an average of 17 years.
-The average household has 6 members with an average of 5 smart devices. Only 2 percent of the Households had not a single smart device, but at the same time, only 42 percent had direct or indirect access to a laptop or computer. So the main body of smart devices consists of smartphones with a negligible portion of tablets.
-The average total amount of electrical devices is around 11 electrical appliances per house.</p>

+<h2 id="Das_Projekt">Das Projekt</h2>
+<p>In einer Umgebung, die auf Wasser- und Sonnenenergie angewiesen ist, mit über sechs Monaten Schnee, häufigen Schneestürmen und Temperaturen bis zu –35 °C, ist die Netzsicherung schwierig.</p>
+<p>Unser Ansatz war es, die im Westen etablierte Vorstellung von Elektrizität als homogenes, zentral erzeugtes Produkt zu hinterfragen und stattdessen die Möglichkeiten eines <strong>prädiktiven, sich selbst korrigierenden und dezentralen Netzes</strong> zu erforschen.</p>
+<p>Anstatt bei einem Sturm einen kompletten Blackout zu riskieren, könnten bei einer Priorisierung der Energieverwendung wichtige Funktionen – etwa Radiotürme oder Krankenhäuser – teilweise weiterbetrieben werden. Die Binarität von Strom / kein Strom würde durch ein System von <strong>Zuteilungen nach Bedarf und Zeitfenstern</strong> ersetzt.<br />
+Langfristig war die Vision ein <strong>lokaler, prädiktiver Strommarkt</strong>, bei dem Menschen überschüssige Energie verkaufen können.</p>
+<p>Zur Machbarkeitsprüfung führte ich psychologische Akzeptanzstudien durch und sammelte Daten zum lokalen Stromverbrauch. Anschließend simulierte ich einen typischen Strombedarfstag im Key-Kloster und in den umliegenden Dörfern und entwickelte Konzepte für kostengünstige <strong>Smart-Microgrid-Controller</strong>.</p>
+<p>Die hier in Deutschland verfügbaren Netzsteuerboxen kosten mehrere Hundert bis Tausend Euro – keine realistische Lösung für die Bevölkerung vor Ort. Stattdessen planten wir <strong>Raspberry Pi-basierte Systeme</strong>, vernetzt über Ethernet oder lokale Mesh-Netze.</p>
+<h2 id="Forschung">Forschung</h2>
+<p><img src="/images/Key_Monastery_Spiti.png" alt="Das Stromnetz des Key-Klosters" /></p>
+<h2 id="Datenerhebung">Datenerhebung</h2>
+<p>Durch den Besuch öffentlicher Schulen im Englischunterricht konnte ich mit Jugendlichen über den Stromzustand in ihren Haushalten sprechen und umfangreiche Daten erheben. Insgesamt nahmen <strong>145 Teilnehmer aus über sechs Schulen</strong> in etwa <strong>vier Distrikten</strong> teil – alle im indischen Himalaya.</p>
+<p>Der Altersdurchschnitt lag bei 17 Jahren. Durchschnittlich leben 6 Personen pro Haushalt mit etwa 5 Smart-Geräten. Nur 2 % der Haushalte hatten gar keine, 42 % verfügten über Computer oder Laptops.</p>
<blockquote>
-<p>Average quality in summer: 7.1
-Average quality in monsoon: 5.6
-Average quality in autumn: 7.1
-Average quality in winter: 4.0</p>
+<p>Durchschnittliche Stromqualität (1 – 10):<br />
+Sommer: 7,1 Monsun: 5,6 Herbst: 7,1 Winter: 4,0</p>
</blockquote>
-<p>So, as you would expect, during winter, but also when it rains, the felt quality drops by more than 30 percent on average.
-As for the daily supply time, the average sits at 15.1 hours out of 24, meaning the people have electricity only for 62.9 percent of the time, some, as for example the people in Diskit only have a sad 4 hours of daily access. On top of that, this estimation does not account for the snowfalls in Spiti for example, where it is not uncommon to experience 3 consecutive days of powercut or more.
-As the Power Meter is supplied by the government, a solid 82 percent of the houses have a working power meter, if one assumes that the 13 percent who did not know whether they have a power meter, do have one, we can say that around 95% of the houses have a power meter.</p>
-<p>Another goal of the studies was to find out what would incline people to be caring and sharing with the available electricity, something rather unimaginable here in Germany.</p>
-<p>In general, the uninformed openness to delaying usage of electricity on a scale of 1-10 was around 5.5, with the additional information that a smart delay would cause an overall price reduction, the acceptance went up to 6.9, a good 14%. This implies that people would be a lot more inclined to give up conveniences if the benefits have a direct impact on them.</p>
+<p>Im Winter oder bei Regen sinkt die Qualität also deutlich – um über 30 %.<br />
+Im Durchschnitt haben Haushalte <strong>15,1 Stunden Strom pro Tag</strong> (≈ 63 %). Einige Regionen, wie Diskit, nur rund 4 Stunden.</p>
+<p>Etwa 95 % der Haushalte besitzen funktionierende Stromzähler.</p>
+<p>Ein weiteres Ziel war herauszufinden, <strong>was Menschen dazu bewegt, Strom zu teilen oder zu verschieben</strong>.<br />
+Ohne zusätzliche Information lag die Bereitschaft zur Verzögerung des Verbrauchs bei 5,5 / 10 – mit Aussicht auf Kostenvorteile stieg sie auf 6,9.</p>
<h2 id="Simulation">Simulation</h2>
-<p>After collecting all the estimated electric appliances of the local population, I simulated the use of 200 Solar Panels with 300Wp each, once for simultaneous electricity use, and once for mitigated electricity peaks through smart optimization and electricity usage delay.
-<img src="/images/sam_sim.png" alt="SAM Simulation of a local solar system " />
-<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimized" /></p>
-<p>Although solar is definitely not the optimal choice here and generates lots of issues with energy storage and battery charging at negative degrees, we figured that this was the way to go for the project.
-And as you can see, optimizing peak usage can improve solar from generating only one-fifth of the demand in winter to about half the demand in winter. Keeping in mind here, that the added solar farm was only intended to supply additional energy and not replace existing solutions, such a "small" farm would be a real lifesaver there and optimize the limited space in extremely mountainous terrain.</p>
-<h2 id="Closing_words">Closing words</h2>
-<p>There are to sides which the problems can be tackled: we can bring the total energy production up, by adding more panels or electricity by other means, but we can also try and bring the total demand down. This is to be achieved by investing strictly in the most energy-efficient appliances. Even replacing older, not-so-efficient appliances might sometimes be of use.
-But ensuring efficient use is not the only way to bring down the overall demand.</p>
-<p>As introduced as core ideas for the whole project, sharing and delaying will prove immensely useful. How so?
-By sharing, we mean a concept that is already widely applied in the relevant areas. What to do in a Village that has no access to water? Will we send each household out to the faraway river to catch water for their family? Or would we join hands in a community effort to dig a central well used by everyone?</p>
-<p>So, when we look at sharing electricity, how would we apply the concept? We take the appliances that consume the most energy individually and scale them up in order to increase efficiency. For example, in our case, that is most applicable to electric heating. If we manage to heat central community spaces available for everyone, naturally, fewer individual rooms will have to be heated. Similarly, one could declare a room as a public cinema, where people come together and watch Tv on a big Projector. Twice as fun, and conserving a great deal of energy again. Such ideas and others have to be realized in order to be able to match the total demand with the available supply.</p>
-<p>Sadly, the project was never taken up further, and the situation for the people in the Spiti Valley has not improved. Two years ago, a road directly through the mountains was finished, making the population hopeful for an increase in tourism, increasing the chances of the economic viability of improved solutions.
-I spent my time there in the function of a research intern, having no real say in the realization of the project. The problem remains, and I still think that decentral solutions look to be the most promising for this specific location. Of course, the Himalayas present a bit of an extreme location, but that doesn't change the fact that people live there and have a basic human right to electricity.</p>
+<p>Basierend auf den Daten simulierte ich den Einsatz von <strong>200 Solarmodulen à 300 Wp</strong>, einmal mit und einmal ohne intelligente Laststeuerung.</p>
+<p><img src="/images/sam_sim.png" alt="SAM Simulation eines lokalen Solarsystems" /><br />
+<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimiert" /></p>
+<p>Auch wenn Solar nicht optimal ist – vor allem wegen Kälte und Batterielagerung – zeigte sich, dass <strong>intelligente Lastverteilung</strong> den nutzbaren Ertrag im Winter von einem Fünftel auf etwa die Hälfte steigern kann.</p>
+<h2 id="Schlusswort">Schlusswort</h2>
+<p>Das Problem lässt sich aus zwei Richtungen angehen:</p>
+<ol>
+<li><strong>Produktion erhöhen</strong> – mehr Module, mehr Energiequellen.</li>
+<li><strong>Verbrauch senken</strong> – effizientere Geräte, gemeinschaftliche Nutzung.</li>
+</ol>
+<p>Das Konzept des <strong>Teilens und Verzögerns</strong> ist zentral. Wie bei einem gemeinschaftlich genutzten Brunnen kann auch Strom gemeinschaftlich erzeugt und genutzt werden.<br />
+Gemeinsam beheizte Räume oder öffentliche Projekträume sparen Energie und fördern Gemeinschaft.</p>
+<p>Leider wurde das Projekt nie weitergeführt, und die Situation im Spiti-Tal hat sich kaum verbessert. Eine neue Bergstraße gibt Hoffnung auf mehr Tourismus – und damit auf wirtschaftlich tragfähige Lösungen.</p>
+<p>Ich selbst war als Forschungspraktikant beteiligt, ohne Einfluss auf die Umsetzung. Dennoch bin ich überzeugt, dass <strong>dezentrale Lösungen</strong> der richtige Weg sind – gerade für extreme Regionen wie den Himalaya.<br />
+Denn eines bleibt wahr: <strong>Elektrizität ist ein Menschenrecht.</strong></p>

- <p>Being involved with 3D Printers, there is the issue of sustainability that I am confronted with regularly.
-Most 3D printed parts never get recycled and add to the global waste problem, rather than reducing it.
-The printer most certainly doesn’t care what it is printing, the main problem is the dimensional accuracy and the purity of the material. All of this leads to a huge industry, Germany being especially involved, using loads of virgin plastic.</p>
-<p>What can be done about it?
-We can design our products to last longer, we can also print recycling labels on them so they do not have to get burned after their first life. We can take care to only print functional objects, not just fun toys nobody uses.
-Yet, none of that prevents the use of virgin plastics. If you buy a spool of filament, there are some recycled options, but usually at twice the price at worse quality. No wonder recycled filament fails to convince the masses. It is mostly a fun thing YouTubers can pursue, not a valid commercial process.</p>
+ <p>Als 3D-Druck-Enthusiast sehe ich mich regelmäßig mit dem Thema Nachhaltigkeit konfrontiert.<br />
+Die meisten 3D-gedruckten Teile werden nie recycelt und tragen eher zum globalen Müllproblem bei, als es zu reduzieren.<br />
+Das Problem liegt weniger beim Drucker selbst als bei der <strong>dimensionalen Genauigkeit</strong> und der <strong>Reinheit des Materials</strong>. Dies führt zu einer riesigen Industrie, insbesondere in Deutschland, die enorme Mengen an <strong>Neukunststoff</strong> verbraucht.</p>

-<p>In my opinion, the core problem is the nonexistent economic feasibility of a proper recycling process. Identifying the exact material of a piece of trash is a very hard problem, definitely not solved yet. So why do we mix the plastic up in the first place? There is a general willingness of people to recycle, but the system for it is missing.</p>
-<h1 id="The_Master_Plan">The Master Plan</h1>
-<p>I want to get people to wash and separate their trash for me, which are the most expensive steps in the recycling process. There is a willingness to take the extra step, and even if just my mom collects bottle caps for me, that is more than I can realistically use up.
-This only really works when I am thinking in a local and decentral environment.
-The existing recycling facilities clearly will not be able to provide 200 different containers for 200 different types of plastic.
-Starting the process with clean and sorted materials, like bottle caps (HDPE) or failed prints (PET-G), I start off with an advantage.
-Now I have to take apart the trash into evenly sized particles.
-Meet:</p>

-<p>After finding some way to drive this massive axis, I feed the beast and hopefully get tiny pretty uniform plastic bits that are ready to begin the cycle of life anew.</p>
-<p>The solution for the motorization was an old and used garden shredder that still had an intact motor and wiring.
-We cut it in half and attached it to the shredder box.</p>
+<p>Das Kernproblem ist die <strong>fehlende wirtschaftliche Machbarkeit</strong> eines echten Recyclings. Das exakte Identifizieren von Kunststoffarten ist extrem schwierig und noch ungelöst. Es gibt Bereitschaft zu recyceln, aber das System fehlt.</p>

+<p>Mit sauberem, sortiertem Material – etwa Flaschendeckel (HDPE) oder fehlerhafte Drucke (PET-G) – starte ich bereits im Vorteil. Jetzt müssen die Teile noch in <strong>gleichmäßige Partikel</strong> zerkleinert werden.</p>

-<p>After replacing the weak force transmission screw for an industrial coupler, we were ready to try it out. Obviously, there are still security concerns in this prototype, a proper hopper is already being made.</p>
-<p>Nevertheless, we are confident that this shredder will be able to deal with the light sorts of plastic we are thinking of.
-As you can see, I am now able to produce awesome confetti but to do more with the plastic flakes I have to extrude them.</p>
-<h2 id="Meet_the_Filastruder">Meet the Filastruder</h2>
-<p>This is the Filastruder, designed and made by Tim Elmore, in an attempt to create the cheapest viable way to extrude plastic. The biggest cost issue is the tight industrial tolerances in thickness that have to be adhered to. This is in essence what separates good from the bad filament. The industry standard nowadays is at +-0.03mm. Hard to achieve on a DIY setup, but not unheard of. The setup, like any bigger industry equivalent, consists of a motor pressing plastic pellets through a heated screw, extruding molten plastic at the end through a nozzle, and setting the diameter. The leftmost machine is responsible for winding the filament properly onto a spool.</p>
-<p>Here you can see the extrusion process in action.</p>

+Die größten Herausforderungen: <strong>präzise Durchmesserkontrolle</strong> ±0,03 mm, sonst schwankt die Qualität.</p>
+<p>Motor presst Kunststoffpellets durch eine beheizte Schraube, am Ende wird durch die Düse extrudiert und der Durchmesser eingestellt. Links wickelt die Maschine das Filament auf eine Spule.</p>

-<p>The Filastruder is controlled by an Arduino and is highly configurable. The laser sensor visible in the video is already working, but I am missing more direct control over the diameter of the filament.</p>
-<p>When it all really comes down to the single variable of the filament diameter responsible for the quality of my recycled project, a simple Machine Learning optimization directly jumps at me: I have a few variables like winder speed, extrusion speed, heat, and cooling intensity. These variables can be optimized on the fly for an exact diameter. This is actually roughly how virgin filament is produced, commercial facilities just manage much faster.</p>
-<p><img src="/assets/images/recycling_variables.png" alt="The variables in an iterative optimization" /></p>
-<p>So far, I am aware of a few companies and academic projects attempting this process, but none of them manage to get either the quality or the price of other products available. Automatization does not just take out jobs away, I think it can also be a helpful tool, for example tackling environmental issues such as this one.</p>
-<p>This project is very dear to my heart and I plan to investigate it further in the form of a master thesis.
-The realization will require many skills I am already picking up or still need to work on within the Design and Computation program.

-<p>Access to Electricity is a basic human right. At first, that may seem over the top, but if one stops to think what all the little tasks that electricity can indirectly handle for us (lightning, laundry, cooking, freezing, heating, entertaining…) would consume in time and effort if we had to perform them manually, this idea becomes very clear. There are globally around 1 billion people without tier 2 access to electricity.</p>

-<p>People only know the intensity of labor that goes into everything when there is no electricity. And it is not even only about convenience, electricity is an enormous lifesaver in any number of scenarios, think just of hospitals or mobile phone networks that would be rendered completely useless without it. So we can easily agree on a need, a demand for electricity globally, for every person. But what about the supply? Why is there 1 billion undersupplied?
-The Answer: missing profitability. It would be a charity project to supply every last person on earth, not a profitable one. And while charitable projects are noble and should be pursued, the reality within capitalism shows that this is not the way it is going to happen.
-But what if we could come up with technology, or rather, a communal structure, that enables us to supply profitably, and still adapt to both, the difficult external factors (weather issues, remoteness, altitude, etc.) and the smaller purses of the undersupplied?</p>

+<h2 id="Das_Projekt">Das Projekt</h2>
+<p>In einer Umgebung, die auf Wasser- und Sonnenenergie angewiesen ist, mit über sechs Monaten Schnee, häufigen Schneestürmen und Temperaturen bis zu –35 °C, ist die Netzsicherung schwierig.</p>
+<p>Unser Ansatz war es, die im Westen etablierte Vorstellung von Elektrizität als homogenes, zentral erzeugtes Produkt zu hinterfragen und stattdessen die Möglichkeiten eines <strong>prädiktiven, sich selbst korrigierenden und dezentralen Netzes</strong> zu erforschen.</p>
+<p>Anstatt bei einem Sturm einen kompletten Blackout zu riskieren, könnten bei einer Priorisierung der Energieverwendung wichtige Funktionen – etwa Radiotürme oder Krankenhäuser – teilweise weiterbetrieben werden. Die Binarität von Strom / kein Strom würde durch ein System von <strong>Zuteilungen nach Bedarf und Zeitfenstern</strong> ersetzt.<br />
+Langfristig war die Vision ein <strong>lokaler, prädiktiver Strommarkt</strong>, bei dem Menschen überschüssige Energie verkaufen können.</p>
+<p>Zur Machbarkeitsprüfung führte ich psychologische Akzeptanzstudien durch und sammelte Daten zum lokalen Stromverbrauch. Anschließend simulierte ich einen typischen Strombedarfstag im Key-Kloster und in den umliegenden Dörfern und entwickelte Konzepte für kostengünstige <strong>Smart-Microgrid-Controller</strong>.</p>
+<p>Die hier in Deutschland verfügbaren Netzsteuerboxen kosten mehrere Hundert bis Tausend Euro – keine realistische Lösung für die Bevölkerung vor Ort. Stattdessen planten wir <strong>Raspberry Pi-basierte Systeme</strong>, vernetzt über Ethernet oder lokale Mesh-Netze.</p>
+<h2 id="Forschung">Forschung</h2>
+<p><img src="/images/Key_Monastery_Spiti.png" alt="Das Stromnetz des Key-Klosters" /></p>
+<h2 id="Datenerhebung">Datenerhebung</h2>
+<p>Durch den Besuch öffentlicher Schulen im Englischunterricht konnte ich mit Jugendlichen über den Stromzustand in ihren Haushalten sprechen und umfangreiche Daten erheben. Insgesamt nahmen <strong>145 Teilnehmer aus über sechs Schulen</strong> in etwa <strong>vier Distrikten</strong> teil – alle im indischen Himalaya.</p>
+<p>Der Altersdurchschnitt lag bei 17 Jahren. Durchschnittlich leben 6 Personen pro Haushalt mit etwa 5 Smart-Geräten. Nur 2 % der Haushalte hatten gar keine, 42 % verfügten über Computer oder Laptops.</p>
<blockquote>
-<p>Average quality in summer: 7.1
-Average quality in monsoon: 5.6
-Average quality in autumn: 7.1
-Average quality in winter: 4.0</p>
+<p>Durchschnittliche Stromqualität (1 – 10):<br />
+Sommer: 7,1 Monsun: 5,6 Herbst: 7,1 Winter: 4,0</p>
</blockquote>
-<p>So, as you would expect, during winter, but also when it rains, the felt quality drops by more than 30 percent on average.
-As for the daily supply time, the average sits at 15.1 hours out of 24, meaning the people have electricity only for 62.9 percent of the time, some, as for example the people in Diskit only have a sad 4 hours of daily access. On top of that, this estimation does not account for the snowfalls in Spiti for example, where it is not uncommon to experience 3 consecutive days of powercut or more.
-As the Power Meter is supplied by the government, a solid 82 percent of the houses have a working power meter, if one assumes that the 13 percent who did not know whether they have a power meter, do have one, we can say that around 95% of the houses have a power meter.</p>
-<p>Another goal of the studies was to find out what would incline people to be caring and sharing with the available electricity, something rather unimaginable here in Germany.</p>
-<p>In general, the uninformed openness to delaying usage of electricity on a scale of 1-10 was around 5.5, with the additional information that a smart delay would cause an overall price reduction, the acceptance went up to 6.9, a good 14%. This implies that people would be a lot more inclined to give up conveniences if the benefits have a direct impact on them.</p>
+<p>Im Winter oder bei Regen sinkt die Qualität also deutlich – um über 30 %.<br />
+Im Durchschnitt haben Haushalte <strong>15,1 Stunden Strom pro Tag</strong> (≈ 63 %). Einige Regionen, wie Diskit, nur rund 4 Stunden.</p>
+<p>Etwa 95 % der Haushalte besitzen funktionierende Stromzähler.</p>
+<p>Ein weiteres Ziel war herauszufinden, <strong>was Menschen dazu bewegt, Strom zu teilen oder zu verschieben</strong>.<br />
+Ohne zusätzliche Information lag die Bereitschaft zur Verzögerung des Verbrauchs bei 5,5 / 10 – mit Aussicht auf Kostenvorteile stieg sie auf 6,9.</p>
<h2 id="Simulation">Simulation</h2>
-<p>After collecting all the estimated electric appliances of the local population, I simulated the use of 200 Solar Panels with 300Wp each, once for simultaneous electricity use, and once for mitigated electricity peaks through smart optimization and electricity usage delay.
-<img src="/images/sam_sim.png" alt="SAM Simulation of a local solar system " />
-<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimized" /></p>
-<p>Although solar is definitely not the optimal choice here and generates lots of issues with energy storage and battery charging at negative degrees, we figured that this was the way to go for the project.
-And as you can see, optimizing peak usage can improve solar from generating only one-fifth of the demand in winter to about half the demand in winter. Keeping in mind here, that the added solar farm was only intended to supply additional energy and not replace existing solutions, such a "small" farm would be a real lifesaver there and optimize the limited space in extremely mountainous terrain.</p>
-<h2 id="Closing_words">Closing words</h2>
-<p>There are to sides which the problems can be tackled: we can bring the total energy production up, by adding more panels or electricity by other means, but we can also try and bring the total demand down. This is to be achieved by investing strictly in the most energy-efficient appliances. Even replacing older, not-so-efficient appliances might sometimes be of use.
-But ensuring efficient use is not the only way to bring down the overall demand.</p>
-<p>As introduced as core ideas for the whole project, sharing and delaying will prove immensely useful. How so?
-By sharing, we mean a concept that is already widely applied in the relevant areas. What to do in a Village that has no access to water? Will we send each household out to the faraway river to catch water for their family? Or would we join hands in a community effort to dig a central well used by everyone?</p>
-<p>So, when we look at sharing electricity, how would we apply the concept? We take the appliances that consume the most energy individually and scale them up in order to increase efficiency. For example, in our case, that is most applicable to electric heating. If we manage to heat central community spaces available for everyone, naturally, fewer individual rooms will have to be heated. Similarly, one could declare a room as a public cinema, where people come together and watch Tv on a big Projector. Twice as fun, and conserving a great deal of energy again. Such ideas and others have to be realized in order to be able to match the total demand with the available supply.</p>
-<p>Sadly, the project was never taken up further, and the situation for the people in the Spiti Valley has not improved. Two years ago, a road directly through the mountains was finished, making the population hopeful for an increase in tourism, increasing the chances of the economic viability of improved solutions.
-I spent my time there in the function of a research intern, having no real say in the realization of the project. The problem remains, and I still think that decentral solutions look to be the most promising for this specific location. Of course, the Himalayas present a bit of an extreme location, but that doesn't change the fact that people live there and have a basic human right to electricity.</p>
+<p>Basierend auf den Daten simulierte ich den Einsatz von <strong>200 Solarmodulen à 300 Wp</strong>, einmal mit und einmal ohne intelligente Laststeuerung.</p>
+<p><img src="/images/sam_sim.png" alt="SAM Simulation eines lokalen Solarsystems" /><br />
+<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimiert" /></p>
+<p>Auch wenn Solar nicht optimal ist – vor allem wegen Kälte und Batterielagerung – zeigte sich, dass <strong>intelligente Lastverteilung</strong> den nutzbaren Ertrag im Winter von einem Fünftel auf etwa die Hälfte steigern kann.</p>
+<h2 id="Schlusswort">Schlusswort</h2>
+<p>Das Problem lässt sich aus zwei Richtungen angehen:</p>
+<ol>
+<li><strong>Produktion erhöhen</strong> – mehr Module, mehr Energiequellen.</li>
+<li><strong>Verbrauch senken</strong> – effizientere Geräte, gemeinschaftliche Nutzung.</li>
+</ol>
+<p>Das Konzept des <strong>Teilens und Verzögerns</strong> ist zentral. Wie bei einem gemeinschaftlich genutzten Brunnen kann auch Strom gemeinschaftlich erzeugt und genutzt werden.<br />
+Gemeinsam beheizte Räume oder öffentliche Projekträume sparen Energie und fördern Gemeinschaft.</p>
+<p>Leider wurde das Projekt nie weitergeführt, und die Situation im Spiti-Tal hat sich kaum verbessert. Eine neue Bergstraße gibt Hoffnung auf mehr Tourismus – und damit auf wirtschaftlich tragfähige Lösungen.</p>
+<p>Ich selbst war als Forschungspraktikant beteiligt, ohne Einfluss auf die Umsetzung. Dennoch bin ich überzeugt, dass <strong>dezentrale Lösungen</strong> der richtige Weg sind – gerade für extreme Regionen wie den Himalaya.<br />
+Denn eines bleibt wahr: <strong>Elektrizität ist ein Menschenrecht.</strong></p>

-<p>Access to Electricity is a basic human right. At first, that may seem over the top, but if one stops to think what all the little tasks that electricity can indirectly handle for us (lightning, laundry, cooking, freezing, heating, entertaining…) would consume in time and effort if we had to perform them manually, this idea becomes very clear. There are globally around 1 billion people without tier 2 access to electricity.</p>

-<p>People only know the intensity of labor that goes into everything when there is no electricity. And it is not even only about convenience, electricity is an enormous lifesaver in any number of scenarios, think just of hospitals or mobile phone networks that would be rendered completely useless without it. So we can easily agree on a need, a demand for electricity globally, for every person. But what about the supply? Why is there 1 billion undersupplied?
-The Answer: missing profitability. It would be a charity project to supply every last person on earth, not a profitable one. And while charitable projects are noble and should be pursued, the reality within capitalism shows that this is not the way it is going to happen.
-But what if we could come up with technology, or rather, a communal structure, that enables us to supply profitably, and still adapt to both, the difficult external factors (weather issues, remoteness, altitude, etc.) and the smaller purses of the undersupplied?</p>

+<p>Zugang zu Elektrizität ist ein grundlegendes Menschenrecht.

Die Binarität von Strom / kein Strom würde durch ein System von <strong>Zuteilungen nach Bedarf und Zeitfenstern</strong> ersetzt.<br />
+Langfristig war die Vision ein <strong>lokaler, prädiktiver Strommarkt</strong>, bei dem Menschen überschüssige Energie verkaufen können.</p>
+<p>Zur Machbarkeitsprüfung führte ich psychologische Akzeptanzstudien durch und sammelte Daten zum lokalen Stromverbrauch. Anschließend simulierte ich einen typischen Strombedarfstag im Key-Kloster und in den umliegenden Dörfern und entwickelte Konzepte für kostengünstige <strong>Smart-Microgrid-Controller</strong>.</p>
+<p>Die hier in Deutschland verfügbaren Netzsteuerboxen kosten mehrere Hundert bis Tausend Euro – keine realistische Lösung für die Bevölkerung vor Ort. Stattdessen planten wir <strong>Raspberry Pi-basierte Systeme</strong>, vernetzt über Ethernet oder lokale Mesh-Netze.</p>
+<h2 id="Forschung">Forschung</h2>
+<p><img src="/images/Key_Monastery_Spiti.png" alt="Das Stromnetz des Key-Klosters" /></p>
+<h2 id="Datenerhebung">Datenerhebung</h2>
+<p>Durch den Besuch öffentlicher Schulen im Englischunterricht konnte ich mit Jugendlichen über den Stromzustand in ihren Haushalten sprechen und umfangreiche Daten erheben. Insgesamt nahmen <strong>145 Teilnehmer aus über sechs Schulen</strong> in etwa <strong>vier Distrikten</strong> teil – alle im indischen Himalaya.</p>
+<p>Der Altersdurchschnitt lag bei 17 Jahren. Durchschnittlich leben 6 Personen pro Haushalt mit etwa 5 Smart-Geräten. Nur 2 % der Haushalte hatten gar keine, 42 % verfügten über Computer oder Laptops.</p>
<blockquote>
-<p>Average quality in summer: 7.1
-Average quality in monsoon: 5.6
-Average quality in autumn: 7.1
-Average quality in winter: 4.0</p>
+<p>Durchschnittliche Stromqualität (1 – 10):<br />
+Sommer: 7,1 Monsun: 5,6 Herbst: 7,1 Winter: 4,0</p>
</blockquote>
-<p>So, as you would expect, during winter, but also when it rains, the felt quality drops by more than 30 percent on average.
-As for the daily supply time, the average sits at 15.1 hours out of 24, meaning the people have electricity only for 62.9 percent of the time, some, as for example the people in Diskit only have a sad 4 hours of daily access. On top of that, this estimation does not account for the snowfalls in Spiti for example, where it is not uncommon to experience 3 consecutive days of powercut or more.
-As the Power Meter is supplied by the government, a solid 82 percent of the houses have a working power meter, if one assumes that the 13 percent who did not know whether they have a power meter, do have one, we can say that around 95% of the houses have a power meter.</p>
-<p>Another goal of the studies was to find out what would incline people to be caring and sharing with the available electricity, something rather unimaginable here in Germany.</p>
-<p>In general, the uninformed openness to delaying usage of electricity on a scale of 1-10 was around 5.5, with the additional information that a smart delay would cause an overall price reduction, the acceptance went up to 6.9, a good 14%. This implies that people would be a lot more inclined to give up conveniences if the benefits have a direct impact on them.</p>
+<p>Im Winter oder bei Regen sinkt die Qualität also deutlich – um über 30 %.<br />
+Im Durchschnitt haben Haushalte <strong>15,1 Stunden Strom pro Tag</strong> (≈ 63 %). Einige Regionen, wie Diskit, nur rund 4 Stunden.</p>
+<p>Etwa 95 % der Haushalte besitzen funktionierende Stromzähler.</p>
+<p>Ein weiteres Ziel war herauszufinden, <strong>was Menschen dazu bewegt, Strom zu teilen oder zu verschieben</strong>.<br />
+Ohne zusätzliche Information lag die Bereitschaft zur Verzögerung des Verbrauchs bei 5,5 / 10 – mit Aussicht auf Kostenvorteile stieg sie auf 6,9.</p>
<h2 id="Simulation">Simulation</h2>
-<p>After collecting all the estimated electric appliances of the local population, I simulated the use of 200 Solar Panels with 300Wp each, once for simultaneous electricity use, and once for mitigated electricity peaks through smart optimization and electricity usage delay.
-<img src="/images/sam_sim.png" alt="SAM Simulation of a local solar system " />
-<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimized" /></p>
-<p>Although solar is definitely not the optimal choice here and generates lots of issues with energy storage and battery charging at negative degrees, we figured that this was the way to go for the project.
-And as you can see, optimizing peak usage can improve solar from generating only one-fifth of the demand in winter to about half the demand in winter. Keeping in mind here, that the added solar farm was only intended to supply additional energy and not replace existing solutions, such a "small" farm would be a real lifesaver there and optimize the limited space in extremely mountainous terrain.</p>
-<h2 id="Closing_words">Closing words</h2>
-<p>There are to sides which the problems can be tackled: we can bring the total energy production up, by adding more panels or electricity by other means, but we can also try and bring the total demand down. This is to be achieved by investing strictly in the most energy-efficient appliances. Even replacing older, not-so-efficient appliances might sometimes be of use.
-But ensuring efficient use is not the only way to bring down the overall demand.</p>
-<p>As introduced as core ideas for the whole project, sharing and delaying will prove immensely useful. How so?
-By sharing, we mean a concept that is already widely applied in the relevant areas. What to do in a Village that has no access to water? Will we send each household out to the faraway river to catch water for their family? Or would we join hands in a community effort to dig a central well used by everyone?</p>
-<p>So, when we look at sharing electricity, how would we apply the concept? We take the appliances that consume the most energy individually and scale them up in order to increase efficiency. For example, in our case, that is most applicable to electric heating. If we manage to heat central community spaces available for everyone, naturally, fewer individual rooms will have to be heated. Similarly, one could declare a room as a public cinema, where people come together and watch Tv on a big Projector. Twice as fun, and conserving a great deal of energy again. Such ideas and others have to be realized in order to be able to match the total demand with the available supply.</p>
-<p>Sadly, the project was never taken up further, and the situation for the people in the Spiti Valley has not improved. Two years ago, a road directly through the mountains was finished, making the population hopeful for an increase in tourism, increasing the chances of the economic viability of improved solutions.
-I spent my time there in the function of a research intern, having no real say in the realization of the project. The problem remains, and I still think that decentral solutions look to be the most promising for this specific location. Of course, the Himalayas present a bit of an extreme location, but that doesn't change the fact that people live there and have a basic human right to electricity.</p>
+<p>Basierend auf den Daten simulierte ich den Einsatz von <strong>200 Solarmodulen à 300 Wp</strong>, einmal mit und einmal ohne intelligente Laststeuerung.</p>
+<p><img src="/images/sam_sim.png" alt="SAM Simulation eines lokalen Solarsystems" /><br />
+<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimiert" /></p>
+<p>Auch wenn Solar nicht optimal ist – vor allem wegen Kälte und Batterielagerung – zeigte sich, dass <strong>intelligente Lastverteilung</strong> den nutzbaren Ertrag im Winter von einem Fünftel auf etwa die Hälfte steigern kann.</p>
+<h2 id="Schlusswort">Schlusswort</h2>
+<p>Das Problem lässt sich aus zwei Richtungen angehen:</p>
+<ol>
+<li><strong>Produktion erhöhen</strong> – mehr Module, mehr Energiequellen.</li>
+<li><strong>Verbrauch senken</strong> – effizientere Geräte, gemeinschaftliche Nutzung.</li>
+</ol>
+<p>Das Konzept des <strong>Teilens und Verzögerns</strong> ist zentral. Wie bei einem gemeinschaftlich genutzten Brunnen kann auch Strom gemeinschaftlich erzeugt und genutzt werden.<br />
+Gemeinsam beheizte Räume oder öffentliche Projekträume sparen Energie und fördern Gemeinschaft.</p>
+<p>Leider wurde das Projekt nie weitergeführt, und die Situation im Spiti-Tal hat sich kaum verbessert. Eine neue Bergstraße gibt Hoffnung auf mehr Tourismus – und damit auf wirtschaftlich tragfähige Lösungen.</p>
+<p>Ich selbst war als Forschungspraktikant beteiligt, ohne Einfluss auf die Umsetzung. Dennoch bin ich überzeugt, dass <strong>dezentrale Lösungen</strong> der richtige Weg sind – gerade für extreme Regionen wie den Himalaya.<br />
+Denn eines bleibt wahr: <strong>Elektrizität ist ein Menschenrecht.</strong></p>

-<p>While learning about 3D Printing, I was most intrigued by the possibility to modify and repair existing products. While there is an amazing community with lots of good and free models around, naturally I came to a point where I did not find what I was looking for readily designed. I realized this is an essential skill for effectively operating not just 3D Printers, but any productive machine really.</p>
-<p>Since youtube was the place I was learning all about 3D Printing, and all the people that I looked up to there were using Fusion 360 as their CAD Program that’s what I got into.
-In hindsight, that was a pretty good choice and I am in love with the abilities parametric design gives me.
-Below you will find some of my designs.
-The process is something that I enjoy a lot and wish to dive into deeper.</p>
-<p>By trial and error, I already learned a lot about designing specifically for 3D Printing, but I often feel that there are many aesthetic considerations in design that I am not familiar with.
-I want to broaden my general ability to design physical objects, which is something I hope to gain during my master’s.</p>

+<p>Beim Erlernen des 3D-Drucks hat mich vor allem die Möglichkeit fasziniert, bestehende Produkte zu verändern oder zu reparieren.<br />
+Auch wenn es eine großartige Community mit vielen guten und kostenlosen Modellen gibt, bin ich schnell an den Punkt gekommen, an dem ich nicht fand, was ich suchte.<br />
+Mir wurde klar, dass dies eine wesentliche Fähigkeit ist, um nicht nur 3D-Drucker, sondern grundsätzlich jede Art von Produktionsmaschine sinnvoll zu nutzen.</p>
+<p>Da ich alles über 3D-Druck auf YouTube gelernt habe und dort fast alle mit <strong>Fusion 360</strong> arbeiteten, habe ich mich ebenfalls dafür entschieden.<br />
+Rückblickend war das eine sehr gute Wahl – ich habe mich in die Möglichkeiten des <strong>parametrischen Designs</strong> verliebt.<br />
+Unten findest du einige meiner Entwürfe.<br />
+Der Prozess selbst macht mir unglaublich viel Spaß und ich möchte ihn noch weiter vertiefen.</p>
+<p>Durch Ausprobieren habe ich bereits viel darüber gelernt, wie man speziell für den 3D-Druck konstruiert.<br />
+Trotzdem habe ich oft das Gefühl, dass mir ein tieferes Verständnis für <strong>ästhetische Gestaltung</strong> fehlt.<br />
+Ich möchte meine generelle Fähigkeit erweitern, physische Objekte zu entwerfen – etwas, das ich mir im Masterstudium erhoffe.</p>

-<p>Besides coming up with new objects, incorporating the real world is also an interest of mine.</p>
-<h3 id="Interaction_with_real_objects_and_environments">Interaction with real objects and environments</h3>
-<p>In the last few years I have played around with a few smartphone cameras and was always quite sad, that my scans were never quite accurate enough to do cool stuff with them.
-I could not really afford real 3D scanner and had already started cobbling together a raspberry Pi camera with a cheap TOF sensor, which is a simple, but not quite as good replacement for a laser or a lidar sensor, but then Apple came out with the first phones with accessible Lidar sensor.
-Recently, through work at the university I got access to a device with a lidar sensor and started having fun with it.
-See some examples here:</p>

-<p>This last one was scanned with just my smartphone camera. You can see that the quality is notably worse, but considering is was created with just a single, run-of-the-mill smartphone sensor, I think it is still pretty impressive and will certainly do something towards democratizing such technologies and abilities.</p>

+<h3 id="Interaktion_mit_realen_Objekten_und_Umgebungen">Interaktion mit realen Objekten und Umgebungen</h3>
+<p>In den letzten Jahren habe ich mit verschiedenen Smartphone-Kameras experimentiert – leider waren meine Scans meist nicht präzise genug, um wirklich etwas damit anzufangen.<br />
+Ein professioneller 3D-Scanner war zu teuer, also bastelte ich mir eine Kombination aus einer <strong>Raspberry-Pi-Kamera</strong> und einem günstigen <strong>TOF-Sensor</strong>.<br />
+Das Setup ist simpel, aber bei weitem nicht so genau wie Laser- oder LiDAR-Sensoren. Dann brachte Apple die ersten Geräte mit <strong>zugänglichem LiDAR</strong> heraus.</p>
+<p>Durch meine Arbeit an der Universität hatte ich schließlich Zugriff auf ein Gerät mit LiDAR und begann, damit zu experimentieren.<br />
+Ein paar Beispiele siehst du hier:</p>

+<p>Der letzte Scan hier wurde nur mit einer <strong>Smartphone-Kamera</strong> erstellt.<br />
+Man erkennt deutlich, dass die Qualität geringer ist, aber angesichts der einfachen Technik finde ich das Ergebnis beeindruckend –<br />

-<h2 id="Perspective">Perspective</h2>
-<p>What this section is supposed to deliver is the message that I am currently not where I want to be navigating the vast possibilities of CAD. I feel confident enough to approach small repairs around the flat with a new perspective, but I still lack technical expertise when approaching a collection composite parts, having to function together. I still have lots of projects halfdone or half-thought and one major reason is that there is no real critical exchange within my field of study.</p>
-<p>I want more than designing figurines or wearables.
-I want to incorporate 3D printing as a method to extend the abilities of other tools, have mechanical and electrical purposes, be foodsafe and engaging.
-I fell in love with the idea of designing a toy system, inspired by <a href="https://www.kickstarter.com/projects/makeway/makeway-create-intricate-courses-watch-your-marbles-soar">Makeways on Kickstarter</a>, I have already started adding my own parts to their set.</p>
-<p>I dream of my very own 3D printed coffeecup, one that is both foodsafe and dishwasher-surviving. For that, I would have to do quite a bit of material research, but that just makes the idea so much more appealing.
-I would love finding a material composition incorporating waste to stop relying on plastics, or at least on fossile plastics.
-Once in Berlin, I would want to talk to the people at <a href="https://www.kaffeeform.com/en/">Kaffeform</a> producing largely compostable Coffee Cups incorporating a significant amount of old ground espresso, albeit using injection molding for their process.
-The industry selling composite filaments is much more conservative with the percentage of non-plastic additives, because with a nozzle extrusion process there is much more to go wrong.
-Still, I would love to explore that avenue further and think there is a lot to be gained from looking at pellet printers.</p>
-<p>I also credit huge parts of my exploration process into local recycling to the awesome people at <a href="https://preciousplastic.com">Precious Plastic</a>, who I will join over the summer to learn more about their system.</p>
-<p>I find it hard to write anything about CAD without connecting it directly to a manufacturing process.
-And I believe that's a good thing. Always tying a design process to its realization, grounds the process and attaches to it some immediacy.</p>
-<p>For me to become more confident in this process, I am still missing more expertise in organic shapes, so I would be happy to dig more into Blender, an awesome tool that in my mind is far too powerful to dive into it with just youtube lessons.</p>

+<p>Was dieser Abschnitt zeigen soll: Ich bin beim Thema <strong>CAD</strong> noch nicht da, wo ich gerne wäre.<br />
+Ich fühle mich sicher genug, um kleine Reparaturen im Alltag anzugehen,<br />
+aber beim <strong>Konstruieren komplexer Bauteilgruppen</strong>, die zusammen funktionieren müssen, fehlt mir noch technisches Know-how.<br />
+Viele meiner Projekte sind halbfertig – einer der Hauptgründe ist der <strong>Mangel an fachlichem Austausch</strong> in meinem Umfeld.</p>
+<p>Ich möchte mehr als nur Figuren oder Wearables gestalten.<br />
+Ich möchte den <strong>3D-Druck als Werkzeugerweiterung</strong> nutzen –<br />
+für mechanische oder elektrische Anwendungen, lebensmittelechte Objekte, oder einfach Dinge, die begeistern.<br />
+Ich liebe die Idee, ein <strong>Baukastensystem</strong> zu entwickeln.<br />
+Inspiriert von <a href="https://www.kickstarter.com/projects/makeway/makeway-create-intricate-courses-watch-your-marbles-soar">Makeways auf Kickstarter</a> habe ich bereits angefangen, eigene Teile zu entwerfen.</p>
+<p>Ein Traum von mir ist eine <strong>eigene 3D-gedruckte Kaffeetasse</strong>, die sowohl <strong>spülmaschinenfest als auch lebensmittelecht</strong> ist.<br />
+Dafür müsste ich viel Materialforschung betreiben – aber genau das macht es spannend.<br />
+Ich möchte ein Material finden, das <strong>Abfälle</strong> einbezieht, um weniger von <strong>fossilen Kunststoffen</strong> abhängig zu sein.<br />
+In Berlin möchte ich mich mit den Leuten von <a href="https://www.kaffeeform.com/de/">Kaffeform</a> austauschen, die <strong>kompostierbare Becher</strong> aus gebrauchten Espressoresten herstellen (wenn auch per Spritzgussverfahren).</p>
+<p>Die Hersteller von <strong>Komposit-Filamenten</strong> sind bei der Beimischung nicht-plastischer Stoffe sehr vorsichtig,<br />
+weil der <strong>Extrusionsprozess</strong> durch Düsen leicht fehleranfällig ist.<br />
+Trotzdem glaube ich, dass gerade in diesem Bereich noch viel Potenzial steckt – besonders mit <strong>Pelletdruckern</strong>.</p>
+<p>Große Teile meiner Auseinandersetzung mit <strong>lokalem Recycling</strong> verdanke ich den großartigen Leuten von <a href="https://preciousplastic.com">Precious Plastic</a>, deren Open-Source-Designs mich sehr inspiriert haben.<br />
+Ich finde es schwer, über CAD zu schreiben, ohne gleichzeitig über den <strong>Herstellungsprozess</strong> zu sprechen –<br />
+und ich halte das für etwas Gutes.<br />
+Design und Umsetzung gehören für mich zusammen.</p>
+<p>Um noch sicherer zu werden, möchte ich mich stärker auf <strong>organische Formen</strong> konzentrieren.<br />
+Deshalb will ich tiefer in <strong>Blender</strong> einsteigen – ein großartiges Tool, das viel zu mächtig ist, um es nur über YouTube zu lernen.</p>

- <p>Being involved with 3D Printers, there is the issue of sustainability that I am confronted with regularly.
-Most 3D printed parts never get recycled and add to the global waste problem, rather than reducing it.
-The printer most certainly doesn’t care what it is printing, the main problem is the dimensional accuracy and the purity of the material. All of this leads to a huge industry, Germany being especially involved, using loads of virgin plastic.</p>
-<p>What can be done about it?
-We can design our products to last longer, we can also print recycling labels on them so they do not have to get burned after their first life. We can take care to only print functional objects, not just fun toys nobody uses.
-Yet, none of that prevents the use of virgin plastics. If you buy a spool of filament, there are some recycled options, but usually at twice the price at worse quality. No wonder recycled filament fails to convince the masses. It is mostly a fun thing YouTubers can pursue, not a valid commercial process.</p>
+ <p>Als 3D-Druck-Enthusiast sehe ich mich regelmäßig mit dem Thema Nachhaltigkeit konfrontiert.<br />
+Die meisten 3D-gedruckten Teile werden nie recycelt und tragen eher zum globalen Müllproblem bei, als es zu reduzieren.<br />
+Das Problem liegt weniger beim Drucker selbst als bei der <strong>dimensionalen Genauigkeit</strong> und der <strong>Reinheit des Materials</strong>. Dies führt zu einer riesigen Industrie, insbesondere in Deutschland, die enorme Mengen an <strong>Neukunststoff</strong> verbraucht.</p>
+<h3 id="Was_kann_man_tun?">Was kann man tun?</h3>
+<p>Wir können Produkte langlebiger gestalten, Recycling-Labels aufdrucken und nur funktionale Objekte drucken. Dennoch verhindert dies nicht die Nutzung von Neukunststoffen. Recycelter Filament ist oft doppelt so teuer bei schlechterer Qualität – kein Wunder, dass er kaum Verbreitung findet.</p>

-<p>In my opinion, the core problem is the nonexistent economic feasibility of a proper recycling process. Identifying the exact material of a piece of trash is a very hard problem, definitely not solved yet. So why do we mix the plastic up in the first place? There is a general willingness of people to recycle, but the system for it is missing.</p>
-<h1 id="The_Master_Plan">The Master Plan</h1>
-<p>I want to get people to wash and separate their trash for me, which are the most expensive steps in the recycling process. There is a willingness to take the extra step, and even if just my mom collects bottle caps for me, that is more than I can realistically use up.
-This only really works when I am thinking in a local and decentral environment.
-The existing recycling facilities clearly will not be able to provide 200 different containers for 200 different types of plastic.
-Starting the process with clean and sorted materials, like bottle caps (HDPE) or failed prints (PET-G), I start off with an advantage.
-Now I have to take apart the trash into evenly sized particles.
-Meet:</p>

-<p>With these awesome open-source drawings, I was able to cobble together my very own very dangerous plastic shredder.</p>
-<p>After finding some way to drive this massive axis, I feed the beast and hopefully get tiny pretty uniform plastic bits that are ready to begin the cycle of life anew.</p>
-<p>The solution for the motorization was an old and used garden shredder that still had an intact motor and wiring.
-We cut it in half and attached it to the shredder box.</p>
+<p>Das Kernproblem ist die <strong>fehlende wirtschaftliche Machbarkeit</strong> eines echten Recyclings. Das exakte Identifizieren von Kunststoffarten ist extrem schwierig und noch ungelöst. Es gibt Bereitschaft zu recyceln, aber das System fehlt.</p>

+<p>Mit sauberem, sortiertem Material – etwa Flaschendeckel (HDPE) oder fehlerhafte Drucke (PET-G) – starte ich bereits im Vorteil. Jetzt müssen die Teile noch in <strong>gleichmäßige Partikel</strong> zerkleinert werden.</p>

-<p>After replacing the weak force transmission screw for an industrial coupler, we were ready to try it out. Obviously, there are still security concerns in this prototype, a proper hopper is already being made.</p>
-<p>Nevertheless, we are confident that this shredder will be able to deal with the light sorts of plastic we are thinking of.
-As you can see, I am now able to produce awesome confetti but to do more with the plastic flakes I have to extrude them.</p>
-<h2 id="Meet_the_Filastruder">Meet the Filastruder</h2>
-<p>This is the Filastruder, designed and made by Tim Elmore, in an attempt to create the cheapest viable way to extrude plastic. The biggest cost issue is the tight industrial tolerances in thickness that have to be adhered to. This is in essence what separates good from the bad filament. The industry standard nowadays is at +-0.03mm. Hard to achieve on a DIY setup, but not unheard of. The setup, like any bigger industry equivalent, consists of a motor pressing plastic pellets through a heated screw, extruding molten plastic at the end through a nozzle, and setting the diameter. The leftmost machine is responsible for winding the filament properly onto a spool.</p>
-<p>Here you can see the extrusion process in action.</p>
+<p>Nach Austausch der schwachen Kraftübertragungsschraube gegen einen Industrie-Kuppler waren wir startklar. Sicherheit bleibt ein Thema, ein richtiger Trichter ist in Arbeit.</p>

+<p>Der <strong>Filastruder</strong>, entworfen von Tim Elmore, bietet eine kostengünstige Möglichkeit, Filament zu extrudieren.<br />
+Die größten Herausforderungen: <strong>präzise Durchmesserkontrolle</strong> ±0,03 mm, sonst schwankt die Qualität.</p>
+<p>Motor presst Kunststoffpellets durch eine beheizte Schraube, am Ende wird durch die Düse extrudiert und der Durchmesser eingestellt. Links wickelt die Maschine das Filament auf eine Spule.</p>

-<p>The Filastruder is controlled by an Arduino and is highly configurable. The laser sensor visible in the video is already working, but I am missing more direct control over the diameter of the filament.</p>
-<p>When it all really comes down to the single variable of the filament diameter responsible for the quality of my recycled project, a simple Machine Learning optimization directly jumps at me: I have a few variables like winder speed, extrusion speed, heat, and cooling intensity. These variables can be optimized on the fly for an exact diameter. This is actually roughly how virgin filament is produced, commercial facilities just manage much faster.</p>
-<p><img src="/assets/images/recycling_variables.png" alt="The variables in an iterative optimization" /></p>
-<p>So far, I am aware of a few companies and academic projects attempting this process, but none of them manage to get either the quality or the price of other products available. Automatization does not just take out jobs away, I think it can also be a helpful tool, for example tackling environmental issues such as this one.</p>
-<p>This project is very dear to my heart and I plan to investigate it further in the form of a master thesis.
-The realization will require many skills I am already picking up or still need to work on within the Design and Computation program.

-<p>Access to Electricity is a basic human right. At first, that may seem over the top, but if one stops to think what all the little tasks that electricity can indirectly handle for us (lightning, laundry, cooking, freezing, heating, entertaining…) would consume in time and effort if we had to perform them manually, this idea becomes very clear. There are globally around 1 billion people without tier 2 access to electricity.</p>

-<p><img src="/assets/images/electricity_tiers.png" alt="The electricity tiers defined by the UN" /></p>
-<p>People only know the intensity of labor that goes into everything when there is no electricity. And it is not even only about convenience, electricity is an enormous lifesaver in any number of scenarios, think just of hospitals or mobile phone networks that would be rendered completely useless without it. So we can easily agree on a need, a demand for electricity globally, for every person. But what about the supply? Why is there 1 billion undersupplied?
-The Answer: missing profitability. It would be a charity project to supply every last person on earth, not a profitable one. And while charitable projects are noble and should be pursued, the reality within capitalism shows that this is not the way it is going to happen.
-But what if we could come up with technology, or rather, a communal structure, that enables us to supply profitably, and still adapt to both, the difficult external factors (weather issues, remoteness, altitude, etc.) and the smaller purses of the undersupplied?</p>

+<p>Zugang zu Elektrizität ist ein grundlegendes Menschenrecht. Das mag zunächst übertrieben klingen, doch wenn man bedenkt, wie viele kleine Aufgaben der Strom uns indirekt abnimmt – Licht, Wäsche, Kochen, Kühlen, Heizen, Unterhaltung – wird schnell klar, wie viel Zeit und Aufwand ohne Elektrizität nötig wäre.

+Warum also sind immer noch so viele Menschen unterversorgt?<br />
+<strong>Die Antwort: fehlende Rentabilität.</strong> Es wäre ein wohltätiges, aber kein profitables Projekt, jede Person auf der Welt zu versorgen.

-<p>In an environment reliant on hydro-energy and solar (diesel transport is unreliable due to snowed-in mountain roads), over 6 months of snowy winter, frequent snowstorms, and temperatures of up to -35°C, securing the grid is hard.</p>
-<p>Our way to tackle the issue was to reject the in the western society very established notion of electricity as a homogenous product with centralized production and instead researched the possibilities of a predictive, self-correcting, and decentral grid.</p>
-<p>By prioritizing energy usage cases, instead of a full blackout during a storm, essential functions like radio towers and hospitals could be partially powered and maybe stay functioning. The binarity of either having electricity or not would be replaced by assigned quantities and timeslots, in a collective effort to be mindful and distribute the electricity necessity-based.
-The ultimate vision was a live predictive electricity market, where people could even earn money by selling their allotted, but not needed electricity.
-To gauge feasibility, I conducted several psychological acceptance studies and collected data on local electricity demands.
-I simulated a typical day of electricity demand in the Key monastery and the surrounding villages and mapped out the potential to install cost-efficient smart microgrid controllers enabling such an accurate and predictive behavior.
-The smart grid operator boxes available here in Germany cost several hundred, with installation several thousand Euros, not a feasible solution for the Indian population. Instead, we wanted to use Raspberry Pi's, which are interconnected through ethernet cables or local mesh networking.</p>

The questionnaire was as scientific as I could make it in such a situation and geared towards finding the type and number of electric devices in the homes and estimating typical usage scenarios.</p>
-<p>With a total of 145 participants from more than 6 different schools and roughly 4 different districts, all located in the Indian part of the Himalayas, the findings are as follows:</p>
-<p>The participants range from 11 to 53 years, with an average of 17 years.
-The average household has 6 members with an average of 5 smart devices. Only 2 percent of the Households had not a single smart device, but at the same time, only 42 percent had direct or indirect access to a laptop or computer. So the main body of smart devices consists of smartphones with a negligible portion of tablets.

+<p>In einer Umgebung, die auf Wasser- und Sonnenenergie angewiesen ist, mit über sechs Monaten Schnee, häufigen Schneestürmen und Temperaturen bis zu –35 °C, ist die Netzsicherung schwierig.</p>
+<p>Unser Ansatz war es, die im Westen etablierte Vorstellung von Elektrizität als homogenes, zentral erzeugtes Produkt zu hinterfragen und stattdessen die Möglichkeiten eines <strong>prädiktiven, sich selbst korrigierenden und dezentralen Netzes</strong> zu erforschen.</p>
+<p>Anstatt bei einem Sturm einen kompletten Blackout zu riskieren, könnten bei einer Priorisierung der Energieverwendung wichtige Funktionen – etwa Radiotürme oder Krankenhäuser – teilweise weiterbetrieben werden. Die Binarität von Strom / kein Strom würde durch ein System von <strong>Zuteilungen nach Bedarf und Zeitfenstern</strong> ersetzt.<br />
+Langfristig war die Vision ein <strong>lokaler, prädiktiver Strommarkt</strong>, bei dem Menschen überschüssige Energie verkaufen können.</p>
+<p>Zur Machbarkeitsprüfung führte ich psychologische Akzeptanzstudien durch und sammelte Daten zum lokalen Stromverbrauch. Anschließend simulierte ich einen typischen Strombedarfstag im Key-Kloster und in den umliegenden Dörfern und entwickelte Konzepte für kostengünstige <strong>Smart-Microgrid-Controller</strong>.</p>
+<p>Die hier in Deutschland verfügbaren Netzsteuerboxen kosten mehrere Hundert bis Tausend Euro – keine realistische Lösung für die Bevölkerung vor Ort. Stattdessen planten wir <strong>Raspberry Pi-basierte Systeme</strong>, vernetzt über Ethernet oder lokale Mesh-Netze.</p>
+<h2 id="Forschung">Forschung</h2>
+<p><img src="/images/Key_Monastery_Spiti.png" alt="Das Stromnetz des Key-Klosters" /></p>
+<h2 id="Datenerhebung">Datenerhebung</h2>
+<p>Durch den Besuch öffentlicher Schulen im Englischunterricht konnte ich mit Jugendlichen über den Stromzustand in ihren Haushalten sprechen und umfangreiche Daten erheben. Insgesamt nahmen <strong>145 Teilnehmer aus über sechs Schulen</strong> in etwa <strong>vier Distrikten</strong> teil – alle im indischen Himalaya.</p>
+<p>Der Altersdurchschnitt lag bei 17 Jahren. Durchschnittlich leben 6 Personen pro Haushalt mit etwa 5 Smart-Geräten. Nur 2 % der Haushalte hatten gar keine, 42 % verfügten über Computer oder Laptops.</p>
<blockquote>
-<p>Average quality in summer: 7.1
-Average quality in monsoon: 5.6
-Average quality in autumn: 7.1
-Average quality in winter: 4.0</p>
+<p>Durchschnittliche Stromqualität (1 – 10):<br />
+Sommer: 7,1 Monsun: 5,6 Herbst: 7,1 Winter: 4,0</p>
</blockquote>
-<p>So, as you would expect, during winter, but also when it rains, the felt quality drops by more than 30 percent on average.
-As for the daily supply time, the average sits at 15.1 hours out of 24, meaning the people have electricity only for 62.9 percent of the time, some, as for example the people in Diskit only have a sad 4 hours of daily access. On top of that, this estimation does not account for the snowfalls in Spiti for example, where it is not uncommon to experience 3 consecutive days of powercut or more.
-As the Power Meter is supplied by the government, a solid 82 percent of the houses have a working power meter, if one assumes that the 13 percent who did not know whether they have a power meter, do have one, we can say that around 95% of the houses have a power meter.</p>
-<p>Another goal of the studies was to find out what would incline people to be caring and sharing with the available electricity, something rather unimaginable here in Germany.</p>
-<p>In general, the uninformed openness to delaying usage of electricity on a scale of 1-10 was around 5.5, with the additional information that a smart delay would cause an overall price reduction, the acceptance went up to 6.9, a good 14%. This implies that people would be a lot more inclined to give up conveniences if the benefits have a direct impact on them.</p>
+<p>Im Winter oder bei Regen sinkt die Qualität also deutlich – um über 30 %.<br />
+Im Durchschnitt haben Haushalte <strong>15,1 Stunden Strom pro Tag</strong> (≈ 63 %). Einige Regionen, wie Diskit, nur rund 4 Stunden.</p>
+<p>Etwa 95 % der Haushalte besitzen funktionierende Stromzähler.</p>
+<p>Ein weiteres Ziel war herauszufinden, <strong>was Menschen dazu bewegt, Strom zu teilen oder zu verschieben</strong>.<br />
+Ohne zusätzliche Information lag die Bereitschaft zur Verzögerung des Verbrauchs bei 5,5 / 10 – mit Aussicht auf Kostenvorteile stieg sie auf 6,9.</p>
<h2 id="Simulation">Simulation</h2>
-<p>After collecting all the estimated electric appliances of the local population, I simulated the use of 200 Solar Panels with 300Wp each, once for simultaneous electricity use, and once for mitigated electricity peaks through smart optimization and electricity usage delay.
-<img src="/images/sam_sim.png" alt="SAM Simulation of a local solar system " />
-<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimized" /></p>
-<p>Although solar is definitely not the optimal choice here and generates lots of issues with energy storage and battery charging at negative degrees, we figured that this was the way to go for the project.
-And as you can see, optimizing peak usage can improve solar from generating only one-fifth of the demand in winter to about half the demand in winter. Keeping in mind here, that the added solar farm was only intended to supply additional energy and not replace existing solutions, such a "small" farm would be a real lifesaver there and optimize the limited space in extremely mountainous terrain.</p>
-<h2 id="Closing_words">Closing words</h2>
-<p>There are to sides which the problems can be tackled: we can bring the total energy production up, by adding more panels or electricity by other means, but we can also try and bring the total demand down. This is to be achieved by investing strictly in the most energy-efficient appliances. Even replacing older, not-so-efficient appliances might sometimes be of use.
-But ensuring efficient use is not the only way to bring down the overall demand.</p>
-<p>As introduced as core ideas for the whole project, sharing and delaying will prove immensely useful. How so?
-By sharing, we mean a concept that is already widely applied in the relevant areas. What to do in a Village that has no access to water? Will we send each household out to the faraway river to catch water for their family? Or would we join hands in a community effort to dig a central well used by everyone?</p>
-<p>So, when we look at sharing electricity, how would we apply the concept? We take the appliances that consume the most energy individually and scale them up in order to increase efficiency. For example, in our case, that is most applicable to electric heating. If we manage to heat central community spaces available for everyone, naturally, fewer individual rooms will have to be heated. Similarly, one could declare a room as a public cinema, where people come together and watch Tv on a big Projector. Twice as fun, and conserving a great deal of energy again. Such ideas and others have to be realized in order to be able to match the total demand with the available supply.</p>
-<p>Sadly, the project was never taken up further, and the situation for the people in the Spiti Valley has not improved. Two years ago, a road directly through the mountains was finished, making the population hopeful for an increase in tourism, increasing the chances of the economic viability of improved solutions.
-I spent my time there in the function of a research intern, having no real say in the realization of the project. The problem remains, and I still think that decentral solutions look to be the most promising for this specific location. Of course, the Himalayas present a bit of an extreme location, but that doesn't change the fact that people live there and have a basic human right to electricity.</p>
+<p>Basierend auf den Daten simulierte ich den Einsatz von <strong>200 Solarmodulen à 300 Wp</strong>, einmal mit und einmal ohne intelligente Laststeuerung.</p>
+<p><img src="/images/sam_sim.png" alt="SAM Simulation eines lokalen Solarsystems" /><br />
+<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimiert" /></p>
+<p>Auch wenn Solar nicht optimal ist – vor allem wegen Kälte und Batterielagerung – zeigte sich, dass <strong>intelligente Lastverteilung</strong> den nutzbaren Ertrag im Winter von einem Fünftel auf etwa die Hälfte steigern kann.</p>
+<h2 id="Schlusswort">Schlusswort</h2>
+<p>Das Problem lässt sich aus zwei Richtungen angehen:</p>
+<ol>
+<li><strong>Produktion erhöhen</strong> – mehr Module, mehr Energiequellen.</li>
+<li><strong>Verbrauch senken</strong> – effizientere Geräte, gemeinschaftliche Nutzung.</li>
+</ol>
+<p>Das Konzept des <strong>Teilens und Verzögerns</strong> ist zentral. Wie bei einem gemeinschaftlich genutzten Brunnen kann auch Strom gemeinschaftlich erzeugt und genutzt werden.<br />
+Gemeinsam beheizte Räume oder öffentliche Projekträume sparen Energie und fördern Gemeinschaft.</p>
+<p>Leider wurde das Projekt nie weitergeführt, und die Situation im Spiti-Tal hat sich kaum verbessert. Eine neue Bergstraße gibt Hoffnung auf mehr Tourismus – und damit auf wirtschaftlich tragfähige Lösungen.</p>
+<p>Ich selbst war als Forschungspraktikant beteiligt, ohne Einfluss auf die Umsetzung. Dennoch bin ich überzeugt, dass <strong>dezentrale Lösungen</strong> der richtige Weg sind – gerade für extreme Regionen wie den Himalaya.<br />
+Denn eines bleibt wahr: <strong>Elektrizität ist ein Menschenrecht.</strong></p>

-<p>While learning about 3D Printing, I was most intrigued by the possibility to modify and repair existing products. While there is an amazing community with lots of good and free models around, naturally I came to a point where I did not find what I was looking for readily designed. I realized this is an essential skill for effectively operating not just 3D Printers, but any productive machine really.</p>
-<p>Since youtube was the place I was learning all about 3D Printing, and all the people that I looked up to there were using Fusion 360 as their CAD Program that’s what I got into.
-In hindsight, that was a pretty good choice and I am in love with the abilities parametric design gives me.
-Below you will find some of my designs.
-The process is something that I enjoy a lot and wish to dive into deeper.</p>
-<p>By trial and error, I already learned a lot about designing specifically for 3D Printing, but I often feel that there are many aesthetic considerations in design that I am not familiar with.
-I want to broaden my general ability to design physical objects, which is something I hope to gain during my master’s.</p>

+<p>Beim Erlernen des 3D-Drucks hat mich vor allem die Möglichkeit fasziniert, bestehende Produkte zu verändern oder zu reparieren.<br />
+Auch wenn es eine großartige Community mit vielen guten und kostenlosen Modellen gibt, bin ich schnell an den Punkt gekommen, an dem ich nicht fand, was ich suchte.<br />
+Mir wurde klar, dass dies eine wesentliche Fähigkeit ist, um nicht nur 3D-Drucker, sondern grundsätzlich jede Art von Produktionsmaschine sinnvoll zu nutzen.</p>
+<p>Da ich alles über 3D-Druck auf YouTube gelernt habe und dort fast alle mit <strong>Fusion 360</strong> arbeiteten, habe ich mich ebenfalls dafür entschieden.<br />
+Rückblickend war das eine sehr gute Wahl – ich habe mich in die Möglichkeiten des <strong>parametrischen Designs</strong> verliebt.<br />
+Unten findest du einige meiner Entwürfe.<br />
+Der Prozess selbst macht mir unglaublich viel Spaß und ich möchte ihn noch weiter vertiefen.</p>
+<p>Durch Ausprobieren habe ich bereits viel darüber gelernt, wie man speziell für den 3D-Druck konstruiert.<br />
+Trotzdem habe ich oft das Gefühl, dass mir ein tieferes Verständnis für <strong>ästhetische Gestaltung</strong> fehlt.<br />
+Ich möchte meine generelle Fähigkeit erweitern, physische Objekte zu entwerfen – etwas, das ich mir im Masterstudium erhoffe.</p>

-<p>Besides coming up with new objects, incorporating the real world is also an interest of mine.</p>
-<h3 id="Interaction_with_real_objects_and_environments">Interaction with real objects and environments</h3>
-<p>In the last few years I have played around with a few smartphone cameras and was always quite sad, that my scans were never quite accurate enough to do cool stuff with them.
-I could not really afford real 3D scanner and had already started cobbling together a raspberry Pi camera with a cheap TOF sensor, which is a simple, but not quite as good replacement for a laser or a lidar sensor, but then Apple came out with the first phones with accessible Lidar sensor.
-Recently, through work at the university I got access to a device with a lidar sensor and started having fun with it.
-See some examples here:</p>

-<p>This last one was scanned with just my smartphone camera. You can see that the quality is notably worse, but considering is was created with just a single, run-of-the-mill smartphone sensor, I think it is still pretty impressive and will certainly do something towards democratizing such technologies and abilities.</p>

+<h3 id="Interaktion_mit_realen_Objekten_und_Umgebungen">Interaktion mit realen Objekten und Umgebungen</h3>
+<p>In den letzten Jahren habe ich mit verschiedenen Smartphone-Kameras experimentiert – leider waren meine Scans meist nicht präzise genug, um wirklich etwas damit anzufangen.<br />
+Ein professioneller 3D-Scanner war zu teuer, also bastelte ich mir eine Kombination aus einer <strong>Raspberry-Pi-Kamera</strong> und einem günstigen <strong>TOF-Sensor</strong>.<br />
+Das Setup ist simpel, aber bei weitem nicht so genau wie Laser- oder LiDAR-Sensoren. Dann brachte Apple die ersten Geräte mit <strong>zugänglichem LiDAR</strong> heraus.</p>
+<p>Durch meine Arbeit an der Universität hatte ich schließlich Zugriff auf ein Gerät mit LiDAR und begann, damit zu experimentieren.<br />
+Ein paar Beispiele siehst du hier:</p>

+<p>Der letzte Scan hier wurde nur mit einer <strong>Smartphone-Kamera</strong> erstellt.<br />
+Man erkennt deutlich, dass die Qualität geringer ist, aber angesichts der einfachen Technik finde ich das Ergebnis beeindruckend –<br />

-<h2 id="Perspective">Perspective</h2>
-<p>What this section is supposed to deliver is the message that I am currently not where I want to be navigating the vast possibilities of CAD. I feel confident enough to approach small repairs around the flat with a new perspective, but I still lack technical expertise when approaching a collection composite parts, having to function together. I still have lots of projects halfdone or half-thought and one major reason is that there is no real critical exchange within my field of study.</p>
-<p>I want more than designing figurines or wearables.
-I want to incorporate 3D printing as a method to extend the abilities of other tools, have mechanical and electrical purposes, be foodsafe and engaging.
-I fell in love with the idea of designing a toy system, inspired by <a href="https://www.kickstarter.com/projects/makeway/makeway-create-intricate-courses-watch-your-marbles-soar">Makeways on Kickstarter</a>, I have already started adding my own parts to their set.</p>
-<p>I dream of my very own 3D printed coffeecup, one that is both foodsafe and dishwasher-surviving. For that, I would have to do quite a bit of material research, but that just makes the idea so much more appealing.
-I would love finding a material composition incorporating waste to stop relying on plastics, or at least on fossile plastics.
-Once in Berlin, I would want to talk to the people at <a href="https://www.kaffeeform.com/en/">Kaffeform</a> producing largely compostable Coffee Cups incorporating a significant amount of old ground espresso, albeit using injection molding for their process.
-The industry selling composite filaments is much more conservative with the percentage of non-plastic additives, because with a nozzle extrusion process there is much more to go wrong.
-Still, I would love to explore that avenue further and think there is a lot to be gained from looking at pellet printers.</p>
-<p>I also credit huge parts of my exploration process into local recycling to the awesome people at <a href="https://preciousplastic.com">Precious Plastic</a>, who I will join over the summer to learn more about their system.</p>
-<p>I find it hard to write anything about CAD without connecting it directly to a manufacturing process.
-And I believe that's a good thing. Always tying a design process to its realization, grounds the process and attaches to it some immediacy.</p>
-<p>For me to become more confident in this process, I am still missing more expertise in organic shapes, so I would be happy to dig more into Blender, an awesome tool that in my mind is far too powerful to dive into it with just youtube lessons.</p>

+<p>Was dieser Abschnitt zeigen soll: Ich bin beim Thema <strong>CAD</strong> noch nicht da, wo ich gerne wäre.<br />
+Ich fühle mich sicher genug, um kleine Reparaturen im Alltag anzugehen,<br />
+aber beim <strong>Konstruieren komplexer Bauteilgruppen</strong>, die zusammen funktionieren müssen, fehlt mir noch technisches Know-how.<br />
+Viele meiner Projekte sind halbfertig – einer der Hauptgründe ist der <strong>Mangel an fachlichem Austausch</strong> in meinem Umfeld.</p>
+<p>Ich möchte mehr als nur Figuren oder Wearables gestalten.<br />
+Ich möchte den <strong>3D-Druck als Werkzeugerweiterung</strong> nutzen –<br />
+für mechanische oder elektrische Anwendungen, lebensmittelechte Objekte, oder einfach Dinge, die begeistern.<br />
+Ich liebe die Idee, ein <strong>Baukastensystem</strong> zu entwickeln.<br />
+Inspiriert von <a href="https://www.kickstarter.com/projects/makeway/makeway-create-intricate-courses-watch-your-marbles-soar">Makeways auf Kickstarter</a> habe ich bereits angefangen, eigene Teile zu entwerfen.</p>
+<p>Ein Traum von mir ist eine <strong>eigene 3D-gedruckte Kaffeetasse</strong>, die sowohl <strong>spülmaschinenfest als auch lebensmittelecht</strong> ist.<br />
+Dafür müsste ich viel Materialforschung betreiben – aber genau das macht es spannend.<br />
+Ich möchte ein Material finden, das <strong>Abfälle</strong> einbezieht, um weniger von <strong>fossilen Kunststoffen</strong> abhängig zu sein.<br />
+In Berlin möchte ich mich mit den Leuten von <a href="https://www.kaffeeform.com/de/">Kaffeform</a> austauschen, die <strong>kompostierbare Becher</strong> aus gebrauchten Espressoresten herstellen (wenn auch per Spritzgussverfahren).</p>
+<p>Die Hersteller von <strong>Komposit-Filamenten</strong> sind bei der Beimischung nicht-plastischer Stoffe sehr vorsichtig,<br />
+weil der <strong>Extrusionsprozess</strong> durch Düsen leicht fehleranfällig ist.<br />
+Trotzdem glaube ich, dass gerade in diesem Bereich noch viel Potenzial steckt – besonders mit <strong>Pelletdruckern</strong>.</p>
+<p>Große Teile meiner Auseinandersetzung mit <strong>lokalem Recycling</strong> verdanke ich den großartigen Leuten von <a href="https://preciousplastic.com">Precious Plastic</a>, deren Open-Source-Designs mich sehr inspiriert haben.<br />
+Ich finde es schwer, über CAD zu schreiben, ohne gleichzeitig über den <strong>Herstellungsprozess</strong> zu sprechen –<br />
+und ich halte das für etwas Gutes.<br />
+Design und Umsetzung gehören für mich zusammen.</p>
+<p>Um noch sicherer zu werden, möchte ich mich stärker auf <strong>organische Formen</strong> konzentrieren.<br />
+Deshalb will ich tiefer in <strong>Blender</strong> einsteigen – ein großartiges Tool, das viel zu mächtig ist, um es nur über YouTube zu lernen.</p>

-<p>Access to Electricity is a basic human right. At first, that may seem over the top, but if one stops to think what all the little tasks that electricity can indirectly handle for us (lightning, laundry, cooking, freezing, heating, entertaining…) would consume in time and effort if we had to perform them manually, this idea becomes very clear. There are globally around 1 billion people without tier 2 access to electricity.</p>

-<p><img src="/assets/images/electricity_tiers.png" alt="The electricity tiers defined by the UN" /></p>
-<p>People only know the intensity of labor that goes into everything when there is no electricity. And it is not even only about convenience, electricity is an enormous lifesaver in any number of scenarios, think just of hospitals or mobile phone networks that would be rendered completely useless without it. So we can easily agree on a need, a demand for electricity globally, for every person. But what about the supply? Why is there 1 billion undersupplied?
-The Answer: missing profitability. It would be a charity project to supply every last person on earth, not a profitable one. And while charitable projects are noble and should be pursued, the reality within capitalism shows that this is not the way it is going to happen.
-But what if we could come up with technology, or rather, a communal structure, that enables us to supply profitably, and still adapt to both, the difficult external factors (weather issues, remoteness, altitude, etc.) and the smaller purses of the undersupplied?</p>
-<h3 id="Location">Location</h3>
-<p>Towards the end of 2018, I spent 4 months in northern India, on a research project with the IIT Kharagpur.
-The goal was to work on one of the 17 UN-defined sustainable development goals – electricity.</p>
-<p>Worldwide, an estimated 1 billion people have no or insubstantial access to the grid.
-Some of them live here, in the Key Monastery in the Spiti Valley at around 3500 meters altitude.</p>

+<p>Zugang zu Elektrizität ist ein grundlegendes Menschenrecht. Das mag zunächst übertrieben klingen, doch wenn man bedenkt, wie viele kleine Aufgaben der Strom uns indirekt abnimmt – Licht, Wäsche, Kochen, Kühlen, Heizen, Unterhaltung – wird schnell klar, wie viel Zeit und Aufwand ohne Elektrizität nötig wäre. Weltweit leben etwa <strong>eine Milliarde Menschen</strong> ohne Zugang zu Strom auf dem sogenannten Tier-2-Level.</p>

+<p>Menschen erkennen erst dann, wie viel Arbeit in alltäglichen Dingen steckt, wenn sie keinen Strom haben. Doch es geht dabei nicht nur um Bequemlichkeit – Elektrizität rettet Leben: Krankenhäuser, Telekommunikation, Kühlung von Medikamenten – all das hängt davon ab.<br />
+Warum also sind immer noch so viele Menschen unterversorgt?<br />
+<strong>Die Antwort: fehlende Rentabilität.</strong> Es wäre ein wohltätiges, aber kein profitables Projekt, jede Person auf der Welt zu versorgen. Doch was, wenn wir eine Struktur finden könnten, die <strong>wirtschaftlich tragfähig</strong> ist und sich gleichzeitig an schwierige Bedingungen (Wetter, Abgeschiedenheit, Höhenlage) sowie an kleinere Einkommen anpassen kann?</p>

-<h2 id="The_Project">The Project</h2>
-<p>In an environment reliant on hydro-energy and solar (diesel transport is unreliable due to snowed-in mountain roads), over 6 months of snowy winter, frequent snowstorms, and temperatures of up to -35°C, securing the grid is hard.</p>
-<p>Our way to tackle the issue was to reject the in the western society very established notion of electricity as a homogenous product with centralized production and instead researched the possibilities of a predictive, self-correcting, and decentral grid.</p>
-<p>By prioritizing energy usage cases, instead of a full blackout during a storm, essential functions like radio towers and hospitals could be partially powered and maybe stay functioning. The binarity of either having electricity or not would be replaced by assigned quantities and timeslots, in a collective effort to be mindful and distribute the electricity necessity-based.
-The ultimate vision was a live predictive electricity market, where people could even earn money by selling their allotted, but not needed electricity.
-To gauge feasibility, I conducted several psychological acceptance studies and collected data on local electricity demands.
-I simulated a typical day of electricity demand in the Key monastery and the surrounding villages and mapped out the potential to install cost-efficient smart microgrid controllers enabling such an accurate and predictive behavior.
-The smart grid operator boxes available here in Germany cost several hundred, with installation several thousand Euros, not a feasible solution for the Indian population. Instead, we wanted to use Raspberry Pi's, which are interconnected through ethernet cables or local mesh networking.</p>

-<h2 id="Data_Collection">Data Collection</h2>
-<p>Building a questionnaire and visiting public schools during their English Classes, I had the chance to speak to a range of teenagers, answering questions about the state of electricity in their homes, generating more data than I could have accomplished running from door to door without any skills speaking local dialects. The questionnaire was as scientific as I could make it in such a situation and geared towards finding the type and number of electric devices in the homes and estimating typical usage scenarios.</p>
-<p>With a total of 145 participants from more than 6 different schools and roughly 4 different districts, all located in the Indian part of the Himalayas, the findings are as follows:</p>
-<p>The participants range from 11 to 53 years, with an average of 17 years.
-The average household has 6 members with an average of 5 smart devices. Only 2 percent of the Households had not a single smart device, but at the same time, only 42 percent had direct or indirect access to a laptop or computer. So the main body of smart devices consists of smartphones with a negligible portion of tablets.
-The average total amount of electrical devices is around 11 electrical appliances per house.</p>
-<p><strong>Subjective</strong> Quality Rating on a scale of 1 to 10:</p>
+<p>Das ist <strong>Tashi Gang</strong>, ein Dorf nahe des Klosters. Es beherbergt rund 50 Menschen und ist nur drei bis vier Monate im Sommer über eine Straße erreichbar. Den Rest des Jahres sind die Bewohner auf Hubschrauber-Erste-Hilfe angewiesen – erreichbar nur über einen funktionierenden Mobilfunkturm.</p>

+<h2 id="Das_Projekt">Das Projekt</h2>
+<p>In einer Umgebung, die auf Wasser- und Sonnenenergie angewiesen ist, mit über sechs Monaten Schnee, häufigen Schneestürmen und Temperaturen bis zu –35 °C, ist die Netzsicherung schwierig.</p>
+<p>Unser Ansatz war es, die im Westen etablierte Vorstellung von Elektrizität als homogenes, zentral erzeugtes Produkt zu hinterfragen und stattdessen die Möglichkeiten eines <strong>prädiktiven, sich selbst korrigierenden und dezentralen Netzes</strong> zu erforschen.</p>
+<p>Anstatt bei einem Sturm einen kompletten Blackout zu riskieren, könnten bei einer Priorisierung der Energieverwendung wichtige Funktionen – etwa Radiotürme oder Krankenhäuser – teilweise weiterbetrieben werden. Die Binarität von Strom / kein Strom würde durch ein System von <strong>Zuteilungen nach Bedarf und Zeitfenstern</strong> ersetzt.<br />
+Langfristig war die Vision ein <strong>lokaler, prädiktiver Strommarkt</strong>, bei dem Menschen überschüssige Energie verkaufen können.</p>
+<p>Zur Machbarkeitsprüfung führte ich psychologische Akzeptanzstudien durch und sammelte Daten zum lokalen Stromverbrauch. Anschließend simulierte ich einen typischen Strombedarfstag im Key-Kloster und in den umliegenden Dörfern und entwickelte Konzepte für kostengünstige <strong>Smart-Microgrid-Controller</strong>.</p>
+<p>Die hier in Deutschland verfügbaren Netzsteuerboxen kosten mehrere Hundert bis Tausend Euro – keine realistische Lösung für die Bevölkerung vor Ort. Stattdessen planten wir <strong>Raspberry Pi-basierte Systeme</strong>, vernetzt über Ethernet oder lokale Mesh-Netze.</p>
+<h2 id="Forschung">Forschung</h2>
+<p><img src="/images/Key_Monastery_Spiti.png" alt="Das Stromnetz des Key-Klosters" /></p>
+<h2 id="Datenerhebung">Datenerhebung</h2>
+<p>Durch den Besuch öffentlicher Schulen im Englischunterricht konnte ich mit Jugendlichen über den Stromzustand in ihren Haushalten sprechen und umfangreiche Daten erheben. Insgesamt nahmen <strong>145 Teilnehmer aus über sechs Schulen</strong> in etwa <strong>vier Distrikten</strong> teil – alle im indischen Himalaya.</p>
+<p>Der Altersdurchschnitt lag bei 17 Jahren. Durchschnittlich leben 6 Personen pro Haushalt mit etwa 5 Smart-Geräten. Nur 2 % der Haushalte hatten gar keine, 42 % verfügten über Computer oder Laptops.</p>
<blockquote>
-<p>Average quality in summer: 7.1
-Average quality in monsoon: 5.6
-Average quality in autumn: 7.1
-Average quality in winter: 4.0</p>
+<p>Durchschnittliche Stromqualität (1 – 10):<br />
+Sommer: 7,1 Monsun: 5,6 Herbst: 7,1 Winter: 4,0</p>
</blockquote>
-<p>So, as you would expect, during winter, but also when it rains, the felt quality drops by more than 30 percent on average.
-As for the daily supply time, the average sits at 15.1 hours out of 24, meaning the people have electricity only for 62.9 percent of the time, some, as for example the people in Diskit only have a sad 4 hours of daily access. On top of that, this estimation does not account for the snowfalls in Spiti for example, where it is not uncommon to experience 3 consecutive days of powercut or more.
-As the Power Meter is supplied by the government, a solid 82 percent of the houses have a working power meter, if one assumes that the 13 percent who did not know whether they have a power meter, do have one, we can say that around 95% of the houses have a power meter.</p>
-<p>Another goal of the studies was to find out what would incline people to be caring and sharing with the available electricity, something rather unimaginable here in Germany.</p>
-<p>In general, the uninformed openness to delaying usage of electricity on a scale of 1-10 was around 5.5, with the additional information that a smart delay would cause an overall price reduction, the acceptance went up to 6.9, a good 14%. This implies that people would be a lot more inclined to give up conveniences if the benefits have a direct impact on them.</p>
+<p>Im Winter oder bei Regen sinkt die Qualität also deutlich – um über 30 %.<br />
+Im Durchschnitt haben Haushalte <strong>15,1 Stunden Strom pro Tag</strong> (≈ 63 %). Einige Regionen, wie Diskit, nur rund 4 Stunden.</p>
+<p>Etwa 95 % der Haushalte besitzen funktionierende Stromzähler.</p>
+<p>Ein weiteres Ziel war herauszufinden, <strong>was Menschen dazu bewegt, Strom zu teilen oder zu verschieben</strong>.<br />
+Ohne zusätzliche Information lag die Bereitschaft zur Verzögerung des Verbrauchs bei 5,5 / 10 – mit Aussicht auf Kostenvorteile stieg sie auf 6,9.</p>
<h2 id="Simulation">Simulation</h2>
-<p>After collecting all the estimated electric appliances of the local population, I simulated the use of 200 Solar Panels with 300Wp each, once for simultaneous electricity use, and once for mitigated electricity peaks through smart optimization and electricity usage delay.
-<img src="/images/sam_sim.png" alt="SAM Simulation of a local solar system " />
-<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimized" /></p>
-<p>Although solar is definitely not the optimal choice here and generates lots of issues with energy storage and battery charging at negative degrees, we figured that this was the way to go for the project.
-And as you can see, optimizing peak usage can improve solar from generating only one-fifth of the demand in winter to about half the demand in winter. Keeping in mind here, that the added solar farm was only intended to supply additional energy and not replace existing solutions, such a "small" farm would be a real lifesaver there and optimize the limited space in extremely mountainous terrain.</p>
-<h2 id="Closing_words">Closing words</h2>
-<p>There are to sides which the problems can be tackled: we can bring the total energy production up, by adding more panels or electricity by other means, but we can also try and bring the total demand down. This is to be achieved by investing strictly in the most energy-efficient appliances. Even replacing older, not-so-efficient appliances might sometimes be of use.
-But ensuring efficient use is not the only way to bring down the overall demand.</p>
-<p>As introduced as core ideas for the whole project, sharing and delaying will prove immensely useful. How so?
-By sharing, we mean a concept that is already widely applied in the relevant areas. What to do in a Village that has no access to water? Will we send each household out to the faraway river to catch water for their family? Or would we join hands in a community effort to dig a central well used by everyone?</p>
-<p>So, when we look at sharing electricity, how would we apply the concept? We take the appliances that consume the most energy individually and scale them up in order to increase efficiency. For example, in our case, that is most applicable to electric heating. If we manage to heat central community spaces available for everyone, naturally, fewer individual rooms will have to be heated. Similarly, one could declare a room as a public cinema, where people come together and watch Tv on a big Projector. Twice as fun, and conserving a great deal of energy again. Such ideas and others have to be realized in order to be able to match the total demand with the available supply.</p>
-<p>Sadly, the project was never taken up further, and the situation for the people in the Spiti Valley has not improved. Two years ago, a road directly through the mountains was finished, making the population hopeful for an increase in tourism, increasing the chances of the economic viability of improved solutions.
-I spent my time there in the function of a research intern, having no real say in the realization of the project. The problem remains, and I still think that decentral solutions look to be the most promising for this specific location. Of course, the Himalayas present a bit of an extreme location, but that doesn't change the fact that people live there and have a basic human right to electricity.</p>
+<p>Basierend auf den Daten simulierte ich den Einsatz von <strong>200 Solarmodulen à 300 Wp</strong>, einmal mit und einmal ohne intelligente Laststeuerung.</p>
+<p><img src="/images/sam_sim.png" alt="SAM Simulation eines lokalen Solarsystems" /><br />
+<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimiert" /></p>
+<p>Auch wenn Solar nicht optimal ist – vor allem wegen Kälte und Batterielagerung – zeigte sich, dass <strong>intelligente Lastverteilung</strong> den nutzbaren Ertrag im Winter von einem Fünftel auf etwa die Hälfte steigern kann.</p>
+<h2 id="Schlusswort">Schlusswort</h2>
+<p>Das Problem lässt sich aus zwei Richtungen angehen:</p>
+<ol>
+<li><strong>Produktion erhöhen</strong> – mehr Module, mehr Energiequellen.</li>
+<li><strong>Verbrauch senken</strong> – effizientere Geräte, gemeinschaftliche Nutzung.</li>
+</ol>
+<p>Das Konzept des <strong>Teilens und Verzögerns</strong> ist zentral. Wie bei einem gemeinschaftlich genutzten Brunnen kann auch Strom gemeinschaftlich erzeugt und genutzt werden.<br />
+Gemeinsam beheizte Räume oder öffentliche Projekträume sparen Energie und fördern Gemeinschaft.</p>
+<p>Leider wurde das Projekt nie weitergeführt, und die Situation im Spiti-Tal hat sich kaum verbessert. Eine neue Bergstraße gibt Hoffnung auf mehr Tourismus – und damit auf wirtschaftlich tragfähige Lösungen.</p>
+<p>Ich selbst war als Forschungspraktikant beteiligt, ohne Einfluss auf die Umsetzung. Dennoch bin ich überzeugt, dass <strong>dezentrale Lösungen</strong> der richtige Weg sind – gerade für extreme Regionen wie den Himalaya.<br />
+Denn eines bleibt wahr: <strong>Elektrizität ist ein Menschenrecht.</strong></p>

-<p>I love hosting, I love experimenting in the Kitchen. Starting with homebrews was a natural fit for me and during the first wave of Covid-19, I went the whole homebrewer’s route of bottle fermentation and small batches later elevating my game with larger batches of 50 liters and a pressure tank system.</p>
-<p>Starting out, I found it fascinating, how just 4 rather simple ingredients, malt, hops, water and yeast, can form such an incredible range of taste experiences. It was and still is, a tremendous learning experience, where one slowly has to accept not being able to control the process fully and find room for creativity.</p>
-<p>Why do I present such an unrelated non-academic hobby here? I simply do not regard it as unrelated, experimenting and optimizing a process and a workflow, creating optimal conditions for the yeast to do its job feels very similar to approaching a coding project.
-Yeast and what it does fascinates me. Every time I open the latch to release some pressure on the Tank I think of the awesome symbiotic relationships yeast has with humans and how many different strains live there together to create a unique, yet tailored flavor. Several ideas are floating around of changing the brewing process by capturing the created carbon dioxide and using it productively. I could see a car tire being filled with my beer gas, or an algae farm munching away on my CO2 byproducts. Within a closed-loop pressurized system, such ideas actually become realizable and I would love to explore them further.</p>
-<p>I am not yet an expert on algae, but I can manage with yeast and I believe they can coexist and create a more sustainable cycle of production.
-Young Henrys, a brewery in Australia is already incorporating algae into its industrial process:
-<a href="https://younghenrys.com/algae">The Algae project</a></p>
-<p>Such ideas do not come into the industry by themselves: I believe that art and the exploratory discovery of novel techniques are the same things. Good and inventive design can improve society and make steps towards sustainability. I want to be part of that and would love to find new ways of using yeast in other design contexts: See whether I can make them work in a closed circular system, make them calculate things for me, or simply making my next beer taste awesome with just the right amount of fizz.</p>

+<p>Ich liebe es zu veranstalten, ich liebe es, in der Küche zu experimentieren. Mit Homebrews zu starten, war für mich eine natürliche Entscheidung, und während der ersten Covid-19-Welle habe ich den kompletten Heimbräuerweg mit Flaschenfermentation und kleinen Chargen eingeschlagen, später habe ich mein Setup auf 50-Liter-Chargen mit Drucktank-System erweitert.</p>
+<p>Zu Beginn war ich fasziniert, wie aus nur <strong>vier einfachen Zutaten</strong> – Malz, Hopfen, Wasser und Hefe – ein so unglaubliches Spektrum an Geschmackserlebnissen entstehen kann. Es war und ist immer noch ein <strong>tremendales Lernprojekt</strong>, bei dem man langsam akzeptieren muss, dass man den Prozess nicht vollständig kontrollieren kann, und gleichzeitig Raum für Kreativität findet.</p>
+<p>Warum präsentiere ich dieses scheinbar nicht-akademische Hobby hier? Ich sehe es nicht als irrelevant an: <strong>Experimentieren und Optimieren eines Prozesses und Workflows</strong>, optimale Bedingungen für die Hefe zu schaffen, fühlt sich dem Ansatz eines Programmierprojekts sehr ähnlich an.</p>
+<p>Hefe und ihre Wirkung faszinieren mich. Jedes Mal, wenn ich den Verschluss öffne, um etwas Druck aus dem Tank abzulassen, denke ich an die erstaunlichen symbiotischen Beziehungen der Hefe mit Menschen und wie viele verschiedene Stämme zusammenleben, um einen einzigartigen, maßgeschneiderten Geschmack zu erzeugen.<br />
+Es gibt einige Ideen, den Brauprozess zu verändern, indem das erzeugte CO₂ aufgefangen und produktiv genutzt wird – z. B. ein Autoreifen gefüllt mit Biergas oder eine Algenfarm, die das CO₂ aufnimmt. Innerhalb eines <strong>geschlossenen, druckbeaufschlagten Systems</strong> werden solche Ideen tatsächlich realisierbar, und ich möchte sie weiter erforschen.</p>
+<p>Ich bin noch kein Experte für Algen, aber mit Hefe komme ich klar, und ich glaube, dass sie koexistieren und einen nachhaltigeren Produktionszyklus schaffen können.<br />
+Die australische Brauerei Young Henrys integriert Algen bereits in ihren industriellen Prozess: <a href="https://younghenrys.com/algae">The Algae project</a></p>
+<p>Solche Ideen kommen nicht von selbst in die Industrie: Ich glaube, dass Kunst und die experimentelle Entdeckung neuer Techniken dasselbe sind. <strong>Gutes, erfinderisches Design</strong> kann die Gesellschaft verbessern und Schritte in Richtung Nachhaltigkeit gehen. Ich möchte daran teilhaben und neue Wege finden, Hefe in anderen Designkontexten einzusetzen: ob in einem geschlossenen Kreislaufsystem, zum Berechnen von Dingen oder einfach, um mein nächstes Bier mit der perfekten Spritzigkeit zu brauen.</p>

- <p>Being involved with 3D Printers, there is the issue of sustainability that I am confronted with regularly.
-Most 3D printed parts never get recycled and add to the global waste problem, rather than reducing it.
-The printer most certainly doesn’t care what it is printing, the main problem is the dimensional accuracy and the purity of the material. All of this leads to a huge industry, Germany being especially involved, using loads of virgin plastic.</p>
-<p>What can be done about it?
-We can design our products to last longer, we can also print recycling labels on them so they do not have to get burned after their first life. We can take care to only print functional objects, not just fun toys nobody uses.
-Yet, none of that prevents the use of virgin plastics. If you buy a spool of filament, there are some recycled options, but usually at twice the price at worse quality. No wonder recycled filament fails to convince the masses. It is mostly a fun thing YouTubers can pursue, not a valid commercial process.</p>
+ <p>Als 3D-Druck-Enthusiast sehe ich mich regelmäßig mit dem Thema Nachhaltigkeit konfrontiert.<br />
+Die meisten 3D-gedruckten Teile werden nie recycelt und tragen eher zum globalen Müllproblem bei, als es zu reduzieren.<br />
+Das Problem liegt weniger beim Drucker selbst als bei der <strong>dimensionalen Genauigkeit</strong> und der <strong>Reinheit des Materials</strong>. Dies führt zu einer riesigen Industrie, insbesondere in Deutschland, die enorme Mengen an <strong>Neukunststoff</strong> verbraucht.</p>
+<h3 id="Was_kann_man_tun?">Was kann man tun?</h3>
+<p>Wir können Produkte langlebiger gestalten, Recycling-Labels aufdrucken und nur funktionale Objekte drucken. Dennoch verhindert dies nicht die Nutzung von Neukunststoffen. Recycelter Filament ist oft doppelt so teuer bei schlechterer Qualität – kein Wunder, dass er kaum Verbreitung findet.</p>

-<p>In my opinion, the core problem is the nonexistent economic feasibility of a proper recycling process. Identifying the exact material of a piece of trash is a very hard problem, definitely not solved yet. So why do we mix the plastic up in the first place? There is a general willingness of people to recycle, but the system for it is missing.</p>
-<h1 id="The_Master_Plan">The Master Plan</h1>
-<p>I want to get people to wash and separate their trash for me, which are the most expensive steps in the recycling process. There is a willingness to take the extra step, and even if just my mom collects bottle caps for me, that is more than I can realistically use up.
-This only really works when I am thinking in a local and decentral environment.
-The existing recycling facilities clearly will not be able to provide 200 different containers for 200 different types of plastic.
-Starting the process with clean and sorted materials, like bottle caps (HDPE) or failed prints (PET-G), I start off with an advantage.
-Now I have to take apart the trash into evenly sized particles.

-<p>After finding some way to drive this massive axis, I feed the beast and hopefully get tiny pretty uniform plastic bits that are ready to begin the cycle of life anew.</p>
-<p>The solution for the motorization was an old and used garden shredder that still had an intact motor and wiring.
-We cut it in half and attached it to the shredder box.</p>

-<p>After replacing the weak force transmission screw for an industrial coupler, we were ready to try it out. Obviously, there are still security concerns in this prototype, a proper hopper is already being made.</p>
-<p>Nevertheless, we are confident that this shredder will be able to deal with the light sorts of plastic we are thinking of.
-As you can see, I am now able to produce awesome confetti but to do more with the plastic flakes I have to extrude them.</p>
-<h2 id="Meet_the_Filastruder">Meet the Filastruder</h2>
-<p>This is the Filastruder, designed and made by Tim Elmore, in an attempt to create the cheapest viable way to extrude plastic. The biggest cost issue is the tight industrial tolerances in thickness that have to be adhered to. This is in essence what separates good from the bad filament. The industry standard nowadays is at +-0.03mm. Hard to achieve on a DIY setup, but not unheard of. The setup, like any bigger industry equivalent, consists of a motor pressing plastic pellets through a heated screw, extruding molten plastic at the end through a nozzle, and setting the diameter. The leftmost machine is responsible for winding the filament properly onto a spool.</p>
-<p>Here you can see the extrusion process in action.</p>

+Die größten Herausforderungen: <strong>präzise Durchmesserkontrolle</strong> ±0,03 mm, sonst schwankt die Qualität.</p>
+<p>Motor presst Kunststoffpellets durch eine beheizte Schraube, am Ende wird durch die Düse extrudiert und der Durchmesser eingestellt. Links wickelt die Maschine das Filament auf eine Spule.</p>

-<p>The Filastruder is controlled by an Arduino and is highly configurable. The laser sensor visible in the video is already working, but I am missing more direct control over the diameter of the filament.</p>
-<p>When it all really comes down to the single variable of the filament diameter responsible for the quality of my recycled project, a simple Machine Learning optimization directly jumps at me: I have a few variables like winder speed, extrusion speed, heat, and cooling intensity. These variables can be optimized on the fly for an exact diameter. This is actually roughly how virgin filament is produced, commercial facilities just manage much faster.</p>
-<p><img src="/assets/images/recycling_variables.png" alt="The variables in an iterative optimization" /></p>
-<p>So far, I am aware of a few companies and academic projects attempting this process, but none of them manage to get either the quality or the price of other products available. Automatization does not just take out jobs away, I think it can also be a helpful tool, for example tackling environmental issues such as this one.</p>
-<p>This project is very dear to my heart and I plan to investigate it further in the form of a master thesis.
-The realization will require many skills I am already picking up or still need to work on within the Design and Computation program.

-<p>As you can see, the design faces some questionable choices, but all mechanics are homemade from the ground up and I learned a lot. I often struggle to enjoy competitive games and think there is potential in a co-dependent game interface. During early testing, we often found that it enforces player communication since already the tutorial is quite hard to beat.
-Due to me being a leftie, perhaps not entirely smart, I gave player one the keyboard arrows to work with and player two the WASD keys and left and right mouse buttons for grappling and shooting. For the game, it has an interesting side effect, in that players are forced not only to interact through the differing information on each player's screen but also have to physically interact and coordinate the controls.</p>
-<p>As you can perhaps see, the ball-rolling navigation is quite hard to use.

-<p>As you can see, the design faces some questionable choices, but all mechanics are homemade from the ground up and I learned a lot. I often struggle to enjoy competitive games and think there is potential in a co-dependent game interface. During early testing, we often found that it enforces player communication since already the tutorial is quite hard to beat.
-Due to me being a leftie, perhaps not entirely smart, I gave player one the keyboard arrows to work with and player two the WASD keys and left and right mouse buttons for grappling and shooting. For the game, it has an interesting side effect, in that players are forced not only to interact through the differing information on each player's screen but also have to physically interact and coordinate the controls.</p>

-<p>Access to Electricity is a basic human right. At first, that may seem over the top, but if one stops to think what all the little tasks that electricity can indirectly handle for us (lightning, laundry, cooking, freezing, heating, entertaining…) would consume in time and effort if we had to perform them manually, this idea becomes very clear. There are globally around 1 billion people without tier 2 access to electricity.</p>

-<p>People only know the intensity of labor that goes into everything when there is no electricity. And it is not even only about convenience, electricity is an enormous lifesaver in any number of scenarios, think just of hospitals or mobile phone networks that would be rendered completely useless without it. So we can easily agree on a need, a demand for electricity globally, for every person. But what about the supply? Why is there 1 billion undersupplied?
-The Answer: missing profitability. It would be a charity project to supply every last person on earth, not a profitable one. And while charitable projects are noble and should be pursued, the reality within capitalism shows that this is not the way it is going to happen.
-But what if we could come up with technology, or rather, a communal structure, that enables us to supply profitably, and still adapt to both, the difficult external factors (weather issues, remoteness, altitude, etc.) and the smaller purses of the undersupplied?</p>

-<p>In an environment reliant on hydro-energy and solar (diesel transport is unreliable due to snowed-in mountain roads), over 6 months of snowy winter, frequent snowstorms, and temperatures of up to -35°C, securing the grid is hard.</p>
-<p>Our way to tackle the issue was to reject the in the western society very established notion of electricity as a homogenous product with centralized production and instead researched the possibilities of a predictive, self-correcting, and decentral grid.</p>
-<p>By prioritizing energy usage cases, instead of a full blackout during a storm, essential functions like radio towers and hospitals could be partially powered and maybe stay functioning. The binarity of either having electricity or not would be replaced by assigned quantities and timeslots, in a collective effort to be mindful and distribute the electricity necessity-based.
-The ultimate vision was a live predictive electricity market, where people could even earn money by selling their allotted, but not needed electricity.
-To gauge feasibility, I conducted several psychological acceptance studies and collected data on local electricity demands.
-I simulated a typical day of electricity demand in the Key monastery and the surrounding villages and mapped out the potential to install cost-efficient smart microgrid controllers enabling such an accurate and predictive behavior.
-The smart grid operator boxes available here in Germany cost several hundred, with installation several thousand Euros, not a feasible solution for the Indian population. Instead, we wanted to use Raspberry Pi's, which are interconnected through ethernet cables or local mesh networking.</p>

-<p>Building a questionnaire and visiting public schools during their English Classes, I had the chance to speak to a range of teenagers, answering questions about the state of electricity in their homes, generating more data than I could have accomplished running from door to door without any skills speaking local dialects. The questionnaire was as scientific as I could make it in such a situation and geared towards finding the type and number of electric devices in the homes and estimating typical usage scenarios.</p>
-<p>With a total of 145 participants from more than 6 different schools and roughly 4 different districts, all located in the Indian part of the Himalayas, the findings are as follows:</p>
-<p>The participants range from 11 to 53 years, with an average of 17 years.
-The average household has 6 members with an average of 5 smart devices. Only 2 percent of the Households had not a single smart device, but at the same time, only 42 percent had direct or indirect access to a laptop or computer. So the main body of smart devices consists of smartphones with a negligible portion of tablets.
-The average total amount of electrical devices is around 11 electrical appliances per house.</p>

+<h2 id="Das_Projekt">Das Projekt</h2>
+<p>In einer Umgebung, die auf Wasser- und Sonnenenergie angewiesen ist, mit über sechs Monaten Schnee, häufigen Schneestürmen und Temperaturen bis zu –35 °C, ist die Netzsicherung schwierig.</p>
+<p>Unser Ansatz war es, die im Westen etablierte Vorstellung von Elektrizität als homogenes, zentral erzeugtes Produkt zu hinterfragen und stattdessen die Möglichkeiten eines <strong>prädiktiven, sich selbst korrigierenden und dezentralen Netzes</strong> zu erforschen.</p>
+<p>Anstatt bei einem Sturm einen kompletten Blackout zu riskieren, könnten bei einer Priorisierung der Energieverwendung wichtige Funktionen – etwa Radiotürme oder Krankenhäuser – teilweise weiterbetrieben werden. Die Binarität von Strom / kein Strom würde durch ein System von <strong>Zuteilungen nach Bedarf und Zeitfenstern</strong> ersetzt.<br />
+Langfristig war die Vision ein <strong>lokaler, prädiktiver Strommarkt</strong>, bei dem Menschen überschüssige Energie verkaufen können.</p>
+<p>Zur Machbarkeitsprüfung führte ich psychologische Akzeptanzstudien durch und sammelte Daten zum lokalen Stromverbrauch. Anschließend simulierte ich einen typischen Strombedarfstag im Key-Kloster und in den umliegenden Dörfern und entwickelte Konzepte für kostengünstige <strong>Smart-Microgrid-Controller</strong>.</p>
+<p>Die hier in Deutschland verfügbaren Netzsteuerboxen kosten mehrere Hundert bis Tausend Euro – keine realistische Lösung für die Bevölkerung vor Ort. Stattdessen planten wir <strong>Raspberry Pi-basierte Systeme</strong>, vernetzt über Ethernet oder lokale Mesh-Netze.</p>
+<h2 id="Forschung">Forschung</h2>
+<p><img src="/images/Key_Monastery_Spiti.png" alt="Das Stromnetz des Key-Klosters" /></p>
+<h2 id="Datenerhebung">Datenerhebung</h2>
+<p>Durch den Besuch öffentlicher Schulen im Englischunterricht konnte ich mit Jugendlichen über den Stromzustand in ihren Haushalten sprechen und umfangreiche Daten erheben. Insgesamt nahmen <strong>145 Teilnehmer aus über sechs Schulen</strong> in etwa <strong>vier Distrikten</strong> teil – alle im indischen Himalaya.</p>
+<p>Der Altersdurchschnitt lag bei 17 Jahren. Durchschnittlich leben 6 Personen pro Haushalt mit etwa 5 Smart-Geräten. Nur 2 % der Haushalte hatten gar keine, 42 % verfügten über Computer oder Laptops.</p>
<blockquote>
-<p>Average quality in summer: 7.1
-Average quality in monsoon: 5.6
-Average quality in autumn: 7.1
-Average quality in winter: 4.0</p>
+<p>Durchschnittliche Stromqualität (1 – 10):<br />
+Sommer: 7,1 Monsun: 5,6 Herbst: 7,1 Winter: 4,0</p>
</blockquote>
-<p>So, as you would expect, during winter, but also when it rains, the felt quality drops by more than 30 percent on average.
-As for the daily supply time, the average sits at 15.1 hours out of 24, meaning the people have electricity only for 62.9 percent of the time, some, as for example the people in Diskit only have a sad 4 hours of daily access. On top of that, this estimation does not account for the snowfalls in Spiti for example, where it is not uncommon to experience 3 consecutive days of powercut or more.
-As the Power Meter is supplied by the government, a solid 82 percent of the houses have a working power meter, if one assumes that the 13 percent who did not know whether they have a power meter, do have one, we can say that around 95% of the houses have a power meter.</p>
-<p>Another goal of the studies was to find out what would incline people to be caring and sharing with the available electricity, something rather unimaginable here in Germany.</p>
-<p>In general, the uninformed openness to delaying usage of electricity on a scale of 1-10 was around 5.5, with the additional information that a smart delay would cause an overall price reduction, the acceptance went up to 6.9, a good 14%. This implies that people would be a lot more inclined to give up conveniences if the benefits have a direct impact on them.</p>
+<p>Im Winter oder bei Regen sinkt die Qualität also deutlich – um über 30 %.<br />
+Im Durchschnitt haben Haushalte <strong>15,1 Stunden Strom pro Tag</strong> (≈ 63 %). Einige Regionen, wie Diskit, nur rund 4 Stunden.</p>
+<p>Etwa 95 % der Haushalte besitzen funktionierende Stromzähler.</p>
+<p>Ein weiteres Ziel war herauszufinden, <strong>was Menschen dazu bewegt, Strom zu teilen oder zu verschieben</strong>.<br />
+Ohne zusätzliche Information lag die Bereitschaft zur Verzögerung des Verbrauchs bei 5,5 / 10 – mit Aussicht auf Kostenvorteile stieg sie auf 6,9.</p>
<h2 id="Simulation">Simulation</h2>
-<p>After collecting all the estimated electric appliances of the local population, I simulated the use of 200 Solar Panels with 300Wp each, once for simultaneous electricity use, and once for mitigated electricity peaks through smart optimization and electricity usage delay.
-<img src="/images/sam_sim.png" alt="SAM Simulation of a local solar system " />
-<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimized" /></p>
-<p>Although solar is definitely not the optimal choice here and generates lots of issues with energy storage and battery charging at negative degrees, we figured that this was the way to go for the project.
-And as you can see, optimizing peak usage can improve solar from generating only one-fifth of the demand in winter to about half the demand in winter. Keeping in mind here, that the added solar farm was only intended to supply additional energy and not replace existing solutions, such a "small" farm would be a real lifesaver there and optimize the limited space in extremely mountainous terrain.</p>
-<h2 id="Closing_words">Closing words</h2>
-<p>There are to sides which the problems can be tackled: we can bring the total energy production up, by adding more panels or electricity by other means, but we can also try and bring the total demand down. This is to be achieved by investing strictly in the most energy-efficient appliances. Even replacing older, not-so-efficient appliances might sometimes be of use.
-But ensuring efficient use is not the only way to bring down the overall demand.</p>
-<p>As introduced as core ideas for the whole project, sharing and delaying will prove immensely useful. How so?
-By sharing, we mean a concept that is already widely applied in the relevant areas. What to do in a Village that has no access to water? Will we send each household out to the faraway river to catch water for their family? Or would we join hands in a community effort to dig a central well used by everyone?</p>
-<p>So, when we look at sharing electricity, how would we apply the concept? We take the appliances that consume the most energy individually and scale them up in order to increase efficiency. For example, in our case, that is most applicable to electric heating. If we manage to heat central community spaces available for everyone, naturally, fewer individual rooms will have to be heated. Similarly, one could declare a room as a public cinema, where people come together and watch Tv on a big Projector. Twice as fun, and conserving a great deal of energy again. Such ideas and others have to be realized in order to be able to match the total demand with the available supply.</p>
-<p>Sadly, the project was never taken up further, and the situation for the people in the Spiti Valley has not improved. Two years ago, a road directly through the mountains was finished, making the population hopeful for an increase in tourism, increasing the chances of the economic viability of improved solutions.
-I spent my time there in the function of a research intern, having no real say in the realization of the project. The problem remains, and I still think that decentral solutions look to be the most promising for this specific location. Of course, the Himalayas present a bit of an extreme location, but that doesn't change the fact that people live there and have a basic human right to electricity.</p>
+<p>Basierend auf den Daten simulierte ich den Einsatz von <strong>200 Solarmodulen à 300 Wp</strong>, einmal mit und einmal ohne intelligente Laststeuerung.</p>
+<p><img src="/images/sam_sim.png" alt="SAM Simulation eines lokalen Solarsystems" /><br />
+<img src="/images/sam_sim_opt.png" alt="SAM Simulation Optimiert" /></p>
+<p>Auch wenn Solar nicht optimal ist – vor allem wegen Kälte und Batterielagerung – zeigte sich, dass <strong>intelligente Lastverteilung</strong> den nutzbaren Ertrag im Winter von einem Fünftel auf etwa die Hälfte steigern kann.</p>
+<h2 id="Schlusswort">Schlusswort</h2>
+<p>Das Problem lässt sich aus zwei Richtungen angehen:</p>
+<ol>
+<li><strong>Produktion erhöhen</strong> – mehr Module, mehr Energiequellen.</li>
+<li><strong>Verbrauch senken</strong> – effizientere Geräte, gemeinschaftliche Nutzung.</li>
+</ol>
+<p>Das Konzept des <strong>Teilens und Verzögerns</strong> ist zentral. Wie bei einem gemeinschaftlich genutzten Brunnen kann auch Strom gemeinschaftlich erzeugt und genutzt werden.<br />
+Gemeinsam beheizte Räume oder öffentliche Projekträume sparen Energie und fördern Gemeinschaft.</p>
+<p>Leider wurde das Projekt nie weitergeführt, und die Situation im Spiti-Tal hat sich kaum verbessert. Eine neue Bergstraße gibt Hoffnung auf mehr Tourismus – und damit auf wirtschaftlich tragfähige Lösungen.</p>
+<p>Ich selbst war als Forschungspraktikant beteiligt, ohne Einfluss auf die Umsetzung. Dennoch bin ich überzeugt, dass <strong>dezentrale Lösungen</strong> der richtige Weg sind – gerade für extreme Regionen wie den Himalaya.<br />
+Denn eines bleibt wahr: <strong>Elektrizität ist ein Menschenrecht.</strong></p>

+<p>Beim Erlernen des 3D-Drucks hat mich vor allem die Möglichkeit fasziniert, bestehende Produkte zu verändern oder zu reparieren.<br />
+Auch wenn es eine großartige Community mit vielen guten und kostenlosen Modellen gibt, bin ich schnell an den Punkt gekommen, an dem ich nicht fand, was ich suchte.<br />
+Mir wurde klar, dass dies eine wesentliche Fähigkeit ist, um nicht nur 3D-Drucker, sondern grundsätzlich jede Art von Produktionsmaschine sinnvoll zu nutzen.</p>
+<p>Da ich alles über 3D-Druck auf YouTube gelernt habe und dort fast alle mit <strong>Fusion 360</strong> arbeiteten, habe ich mich ebenfalls dafür entschieden.<br />
+Rückblickend war das eine sehr gute Wahl – ich habe mich in die Möglichkeiten des <strong>parametrischen Designs</strong> verliebt.<br />
+Unten findest du einige meiner Entwürfe.<br />
+Der Prozess selbst macht mir unglaublich viel Spaß und ich möchte ihn noch weiter vertiefen.</p>
+<p>Durch Ausprobieren habe ich bereits viel darüber gelernt, wie man speziell für den 3D-Druck konstruiert.<br />
+Trotzdem habe ich oft das Gefühl, dass mir ein tieferes Verständnis für <strong>ästhetische Gestaltung</strong> fehlt.<br />
+Ich möchte meine generelle Fähigkeit erweitern, physische Objekte zu entwerfen – etwas, das ich mir im Masterstudium erhoffe.</p>

-<p>Besides coming up with new objects, incorporating the real world is also an interest of mine.</p>
-<h3 id="Interaction_with_real_objects_and_environments">Interaction with real objects and environments</h3>
-<p>In the last few years I have played around with a few smartphone cameras and was always quite sad, that my scans were never quite accurate enough to do cool stuff with them.
-I could not really afford real 3D scanner and had already started cobbling together a raspberry Pi camera with a cheap TOF sensor, which is a simple, but not quite as good replacement for a laser or a lidar sensor, but then Apple came out with the first phones with accessible Lidar sensor.
-Recently, through work at the university I got access to a device with a lidar sensor and started having fun with it.
-See some examples here:</p>

-<p>This last one was scanned with just my smartphone camera. You can see that the quality is notably worse, but considering is was created with just a single, run-of-the-mill smartphone sensor, I think it is still pretty impressive and will certainly do something towards democratizing such technologies and abilities.</p>

+<p>Neben dem Entwerfen neuer Objekte interessiert mich auch die Integration der <strong>realen Welt</strong> in meine Arbeit.</p>
+<h3 id="Interaktion_mit_realen_Objekten_und_Umgebungen">Interaktion mit realen Objekten und Umgebungen</h3>
+<p>In den letzten Jahren habe ich mit verschiedenen Smartphone-Kameras experimentiert – leider waren meine Scans meist nicht präzise genug, um wirklich etwas damit anzufangen.<br />
+Ein professioneller 3D-Scanner war zu teuer, also bastelte ich mir eine Kombination aus einer <strong>Raspberry-Pi-Kamera</strong> und einem günstigen <strong>TOF-Sensor</strong>.<br />
+Das Setup ist simpel, aber bei weitem nicht so genau wie Laser- oder LiDAR-Sensoren. Dann brachte Apple die ersten Geräte mit <strong>zugänglichem LiDAR</strong> heraus.</p>
+<p>Durch meine Arbeit an der Universität hatte ich schließlich Zugriff auf ein Gerät mit LiDAR und begann, damit zu experimentieren.<br />
+Ein paar Beispiele siehst du hier:</p>
+<div class="sketchfab-embed-wrapper"> <iframe title="DigiLab Hauptraum" frameborder="0" allowfullscreen mozallowfullscreen="true" webkitallowfullscreen="true" allow="autoplay; fullscreen; xr-spatial-tracking" xr-spatial-tracking execution-while-out-of-viewport execution-while-not-rendered web-share width="800" height="600" src="https://sketchfab.com/models/c880892c6b4746bc80717be1f81bf169/embed?ui_theme=dark&dnt=1"> </iframe> </div>

+<p>Der letzte Scan hier wurde nur mit einer <strong>Smartphone-Kamera</strong> erstellt.<br />
+Man erkennt deutlich, dass die Qualität geringer ist, aber angesichts der einfachen Technik finde ich das Ergebnis beeindruckend –<br />
+und es zeigt, wie sehr solche Technologien gerade <strong>demokratisiert</strong> werden.</p>

-<h2 id="Perspective">Perspective</h2>
-<p>What this section is supposed to deliver is the message that I am currently not where I want to be navigating the vast possibilities of CAD. I feel confident enough to approach small repairs around the flat with a new perspective, but I still lack technical expertise when approaching a collection composite parts, having to function together. I still have lots of projects halfdone or half-thought and one major reason is that there is no real critical exchange within my field of study.</p>
-<p>I want more than designing figurines or wearables.
-I want to incorporate 3D printing as a method to extend the abilities of other tools, have mechanical and electrical purposes, be foodsafe and engaging.
-I fell in love with the idea of designing a toy system, inspired by <a href="https://www.kickstarter.com/projects/makeway/makeway-create-intricate-courses-watch-your-marbles-soar">Makeways on Kickstarter</a>, I have already started adding my own parts to their set.</p>
-<p>I dream of my very own 3D printed coffeecup, one that is both foodsafe and dishwasher-surviving. For that, I would have to do quite a bit of material research, but that just makes the idea so much more appealing.
-I would love finding a material composition incorporating waste to stop relying on plastics, or at least on fossile plastics.
-Once in Berlin, I would want to talk to the people at <a href="https://www.kaffeeform.com/en/">Kaffeform</a> producing largely compostable Coffee Cups incorporating a significant amount of old ground espresso, albeit using injection molding for their process.
-The industry selling composite filaments is much more conservative with the percentage of non-plastic additives, because with a nozzle extrusion process there is much more to go wrong.
-Still, I would love to explore that avenue further and think there is a lot to be gained from looking at pellet printers.</p>
-<p>I also credit huge parts of my exploration process into local recycling to the awesome people at <a href="https://preciousplastic.com">Precious Plastic</a>, who I will join over the summer to learn more about their system.</p>
-<p>I find it hard to write anything about CAD without connecting it directly to a manufacturing process.
-And I believe that's a good thing. Always tying a design process to its realization, grounds the process and attaches to it some immediacy.</p>
-<p>For me to become more confident in this process, I am still missing more expertise in organic shapes, so I would be happy to dig more into Blender, an awesome tool that in my mind is far too powerful to dive into it with just youtube lessons.</p>

+<h2 id="Perspektive">Perspektive</h2>
+<p>Was dieser Abschnitt zeigen soll: Ich bin beim Thema <strong>CAD</strong> noch nicht da, wo ich gerne wäre.<br />
+Ich fühle mich sicher genug, um kleine Reparaturen im Alltag anzugehen,<br />
+aber beim <strong>Konstruieren komplexer Bauteilgruppen</strong>, die zusammen funktionieren müssen, fehlt mir noch technisches Know-how.<br />
+Viele meiner Projekte sind halbfertig – einer der Hauptgründe ist der <strong>Mangel an fachlichem Austausch</strong> in meinem Umfeld.</p>
+<p>Ich möchte mehr als nur Figuren oder Wearables gestalten.<br />
+Ich möchte den <strong>3D-Druck als Werkzeugerweiterung</strong> nutzen –<br />
+für mechanische oder elektrische Anwendungen, lebensmittelechte Objekte, oder einfach Dinge, die begeistern.<br />
+Ich liebe die Idee, ein <strong>Baukastensystem</strong> zu entwickeln.<br />
+Inspiriert von <a href="https://www.kickstarter.com/projects/makeway/makeway-create-intricate-courses-watch-your-marbles-soar">Makeways auf Kickstarter</a> habe ich bereits angefangen, eigene Teile zu entwerfen.</p>
+<p>Ein Traum von mir ist eine <strong>eigene 3D-gedruckte Kaffeetasse</strong>, die sowohl <strong>spülmaschinenfest als auch lebensmittelecht</strong> ist.<br />
+Dafür müsste ich viel Materialforschung betreiben – aber genau das macht es spannend.<br />
+Ich möchte ein Material finden, das <strong>Abfälle</strong> einbezieht, um weniger von <strong>fossilen Kunststoffen</strong> abhängig zu sein.<br />
+In Berlin möchte ich mich mit den Leuten von <a href="https://www.kaffeeform.com/de/">Kaffeform</a> austauschen, die <strong>kompostierbare Becher</strong> aus gebrauchten Espressoresten herstellen (wenn auch per Spritzgussverfahren).</p>
+<p>Die Hersteller von <strong>Komposit-Filamenten</strong> sind bei der Beimischung nicht-plastischer Stoffe sehr vorsichtig,<br />
+weil der <strong>Extrusionsprozess</strong> durch Düsen leicht fehleranfällig ist.<br />
+Trotzdem glaube ich, dass gerade in diesem Bereich noch viel Potenzial steckt – besonders mit <strong>Pelletdruckern</strong>.</p>
+<p>Große Teile meiner Auseinandersetzung mit <strong>lokalem Recycling</strong> verdanke ich den großartigen Leuten von <a href="https://preciousplastic.com">Precious Plastic</a>, deren Open-Source-Designs mich sehr inspiriert haben.<br />
+Ich finde es schwer, über CAD zu schreiben, ohne gleichzeitig über den <strong>Herstellungsprozess</strong> zu sprechen –<br />
+und ich halte das für etwas Gutes.<br />
+Design und Umsetzung gehören für mich zusammen.</p>
+<p>Um noch sicherer zu werden, möchte ich mich stärker auf <strong>organische Formen</strong> konzentrieren.<br />
+Deshalb will ich tiefer in <strong>Blender</strong> einsteigen – ein großartiges Tool, das viel zu mächtig ist, um es nur über YouTube zu lernen.</p>

-<p>Besides coming up with new objects, incorporating the real world is also an interest of mine.</p>
-<h3 id="Interaction_with_real_objects_and_environments">Interaction with real objects and environments</h3>
-<p>In the last few years I have played around with a few smartphone cameras and was always quite sad, that my scans were never quite accurate enough to do cool stuff with them.
-I could not really afford real 3D scanner and had already started cobbling together a raspberry Pi camera with a cheap TOF sensor, which is a simple, but not quite as good replacement for a laser or a lidar sensor, but then Apple came out with the first phones with accessible Lidar sensor.
-Recently, through work at the university I got access to a device with a lidar sensor and started having fun with it.
-See some examples here:</p>

-<p>This last one was scanned with just my smartphone camera. You can see that the quality is notably worse, but considering is was created with just a single, run-of-the-mill smartphone sensor, I think it is still pretty impressive and will certainly do something towards democratizing such technologies and abilities.</p>

+<p>In den letzten Jahren habe ich mit verschiedenen Smartphone-Kameras experimentiert – leider waren meine Scans meist nicht präzise genug, um wirklich etwas damit anzufangen.<br />
+Ein professioneller 3D-Scanner war zu teuer, also bastelte ich mir eine Kombination aus einer <strong>Raspberry-Pi-Kamera</strong> und einem günstigen <strong>TOF-Sensor</strong>.<br />
+Das Setup ist simpel, aber bei weitem nicht so genau wie Laser- oder LiDAR-Sensoren. Dann brachte Apple die ersten Geräte mit <strong>zugänglichem LiDAR</strong> heraus.</p>
+<p>Durch meine Arbeit an der Universität hatte ich schließlich Zugriff auf ein Gerät mit LiDAR und begann, damit zu experimentieren.<br />
+Ein paar Beispiele siehst du hier:</p>

+<p>Der letzte Scan hier wurde nur mit einer <strong>Smartphone-Kamera</strong> erstellt.<br />
+Man erkennt deutlich, dass die Qualität geringer ist, aber angesichts der einfachen Technik finde ich das Ergebnis beeindruckend –<br />
+und es zeigt, wie sehr solche Technologien gerade <strong>demokratisiert</strong> werden.</p>

-<h2 id="Perspective">Perspective</h2>
-<p>What this section is supposed to deliver is the message that I am currently not where I want to be navigating the vast possibilities of CAD. I feel confident enough to approach small repairs around the flat with a new perspective, but I still lack technical expertise when approaching a collection composite parts, having to function together. I still have lots of projects halfdone or half-thought and one major reason is that there is no real critical exchange within my field of study.</p>
-<p>I want more than designing figurines or wearables.
-I want to incorporate 3D printing as a method to extend the abilities of other tools, have mechanical and electrical purposes, be foodsafe and engaging.
-I fell in love with the idea of designing a toy system, inspired by <a href="https://www.kickstarter.com/projects/makeway/makeway-create-intricate-courses-watch-your-marbles-soar">Makeways on Kickstarter</a>, I have already started adding my own parts to their set.</p>
-<p>I dream of my very own 3D printed coffeecup, one that is both foodsafe and dishwasher-surviving. For that, I would have to do quite a bit of material research, but that just makes the idea so much more appealing.
-I would love finding a material composition incorporating waste to stop relying on plastics, or at least on fossile plastics.
-Once in Berlin, I would want to talk to the people at <a href="https://www.kaffeeform.com/en/">Kaffeform</a> producing largely compostable Coffee Cups incorporating a significant amount of old ground espresso, albeit using injection molding for their process.
-The industry selling composite filaments is much more conservative with the percentage of non-plastic additives, because with a nozzle extrusion process there is much more to go wrong.
-Still, I would love to explore that avenue further and think there is a lot to be gained from looking at pellet printers.</p>
-<p>I also credit huge parts of my exploration process into local recycling to the awesome people at <a href="https://preciousplastic.com">Precious Plastic</a>, who I will join over the summer to learn more about their system.</p>
-<p>I find it hard to write anything about CAD without connecting it directly to a manufacturing process.
-And I believe that's a good thing. Always tying a design process to its realization, grounds the process and attaches to it some immediacy.</p>
-<p>For me to become more confident in this process, I am still missing more expertise in organic shapes, so I would be happy to dig more into Blender, an awesome tool that in my mind is far too powerful to dive into it with just youtube lessons.</p>

+<p>Was dieser Abschnitt zeigen soll: Ich bin beim Thema <strong>CAD</strong> noch nicht da, wo ich gerne wäre.<br />
+Ich fühle mich sicher genug, um kleine Reparaturen im Alltag anzugehen,<br />
+aber beim <strong>Konstruieren komplexer Bauteilgruppen</strong>, die zusammen funktionieren müssen, fehlt mir noch technisches Know-how.<br />
+Viele meiner Projekte sind halbfertig – einer der Hauptgründe ist der <strong>Mangel an fachlichem Austausch</strong> in meinem Umfeld.</p>
+<p>Ich möchte mehr als nur Figuren oder Wearables gestalten.<br />
+Ich möchte den <strong>3D-Druck als Werkzeugerweiterung</strong> nutzen –<br />
+für mechanische oder elektrische Anwendungen, lebensmittelechte Objekte, oder einfach Dinge, die begeistern.<br />
+Ich liebe die Idee, ein <strong>Baukastensystem</strong> zu entwickeln.<br />
+Inspiriert von <a href="https://www.kickstarter.com/projects/makeway/makeway-create-intricate-courses-watch-your-marbles-soar">Makeways auf Kickstarter</a> habe ich bereits angefangen, eigene Teile zu entwerfen.</p>
+<p>Ein Traum von mir ist eine <strong>eigene 3D-gedruckte Kaffeetasse</strong>, die sowohl <strong>spülmaschinenfest als auch lebensmittelecht</strong> ist.<br />
+Dafür müsste ich viel Materialforschung betreiben – aber genau das macht es spannend.<br />
+Ich möchte ein Material finden, das <strong>Abfälle</strong> einbezieht, um weniger von <strong>fossilen Kunststoffen</strong> abhängig zu sein.<br />
+In Berlin möchte ich mich mit den Leuten von <a href="https://www.kaffeeform.com/de/">Kaffeform</a> austauschen, die <strong>kompostierbare Becher</strong> aus gebrauchten Espressoresten herstellen (wenn auch per Spritzgussverfahren).</p>
+<p>Die Hersteller von <strong>Komposit-Filamenten</strong> sind bei der Beimischung nicht-plastischer Stoffe sehr vorsichtig,<br />
+weil der <strong>Extrusionsprozess</strong> durch Düsen leicht fehleranfällig ist.<br />
+Trotzdem glaube ich, dass gerade in diesem Bereich noch viel Potenzial steckt – besonders mit <strong>Pelletdruckern</strong>.</p>
+<p>Große Teile meiner Auseinandersetzung mit <strong>lokalem Recycling</strong> verdanke ich den großartigen Leuten von <a href="https://preciousplastic.com">Precious Plastic</a>, deren Open-Source-Designs mich sehr inspiriert haben.<br />
+Ich finde es schwer, über CAD zu schreiben, ohne gleichzeitig über den <strong>Herstellungsprozess</strong> zu sprechen –<br />
+und ich halte das für etwas Gutes.<br />
+Design und Umsetzung gehören für mich zusammen.</p>
+<p>Um noch sicherer zu werden, möchte ich mich stärker auf <strong>organische Formen</strong> konzentrieren.<br />
+Deshalb will ich tiefer in <strong>Blender</strong> einsteigen – ein großartiges Tool, das viel zu mächtig ist, um es nur über YouTube zu lernen.</p>

- <p>Being involved with 3D Printers, there is the issue of sustainability that I am confronted with regularly.
-Most 3D printed parts never get recycled and add to the global waste problem, rather than reducing it.
-The printer most certainly doesn’t care what it is printing, the main problem is the dimensional accuracy and the purity of the material. All of this leads to a huge industry, Germany being especially involved, using loads of virgin plastic.</p>
-<p>What can be done about it?
-We can design our products to last longer, we can also print recycling labels on them so they do not have to get burned after their first life. We can take care to only print functional objects, not just fun toys nobody uses.
-Yet, none of that prevents the use of virgin plastics. If you buy a spool of filament, there are some recycled options, but usually at twice the price at worse quality. No wonder recycled filament fails to convince the masses. It is mostly a fun thing YouTubers can pursue, not a valid commercial process.</p>
+ <p>Als 3D-Druck-Enthusiast sehe ich mich regelmäßig mit dem Thema Nachhaltigkeit konfrontiert.<br />
+Die meisten 3D-gedruckten Teile werden nie recycelt und tragen eher zum globalen Müllproblem bei, als es zu reduzieren.<br />
+Das Problem liegt weniger beim Drucker selbst als bei der <strong>dimensionalen Genauigkeit</strong> und der <strong>Reinheit des Materials</strong>. Dies führt zu einer riesigen Industrie, insbesondere in Deutschland, die enorme Mengen an <strong>Neukunststoff</strong> verbraucht.</p>
+<h3 id="Was_kann_man_tun?">Was kann man tun?</h3>
+<p>Wir können Produkte langlebiger gestalten, Recycling-Labels aufdrucken und nur funktionale Objekte drucken. Dennoch verhindert dies nicht die Nutzung von Neukunststoffen. Recycelter Filament ist oft doppelt so teuer bei schlechterer Qualität – kein Wunder, dass er kaum Verbreitung findet.</p>

-<p>In my opinion, the core problem is the nonexistent economic feasibility of a proper recycling process. Identifying the exact material of a piece of trash is a very hard problem, definitely not solved yet. So why do we mix the plastic up in the first place? There is a general willingness of people to recycle, but the system for it is missing.</p>
-<h1 id="The_Master_Plan">The Master Plan</h1>
-<p>I want to get people to wash and separate their trash for me, which are the most expensive steps in the recycling process. There is a willingness to take the extra step, and even if just my mom collects bottle caps for me, that is more than I can realistically use up.
-This only really works when I am thinking in a local and decentral environment.
-The existing recycling facilities clearly will not be able to provide 200 different containers for 200 different types of plastic.
-Starting the process with clean and sorted materials, like bottle caps (HDPE) or failed prints (PET-G), I start off with an advantage.
-Now I have to take apart the trash into evenly sized particles.
-Meet:</p>
-<h2 id="The_Shredder">The Shredder</h2>
-<p>We built the Precious Plastic Shredder!</p>

-<p>With these awesome open-source drawings, I was able to cobble together my very own very dangerous plastic shredder.</p>
-<p>After finding some way to drive this massive axis, I feed the beast and hopefully get tiny pretty uniform plastic bits that are ready to begin the cycle of life anew.</p>
-<p>The solution for the motorization was an old and used garden shredder that still had an intact motor and wiring.
-We cut it in half and attached it to the shredder box.</p>
+<p>Das Kernproblem ist die <strong>fehlende wirtschaftliche Machbarkeit</strong> eines echten Recyclings. Das exakte Identifizieren von Kunststoffarten ist extrem schwierig und noch ungelöst. Es gibt Bereitschaft zu recyceln, aber das System fehlt.</p>
+<h1 id="Der_Masterplan">Der Masterplan</h1>
+<p>Ich möchte Menschen motivieren, ihren Müll <strong>zu waschen und zu sortieren</strong>, die teuersten Schritte im Recyclingprozess. Selbst kleine Beiträge, wie meine Mutter, die Flaschendeckel sammelt, sind wertvoll.<br />
+Dies funktioniert nur in einem <strong>lokalen, dezentralen Umfeld</strong>. Existierende Recyclinganlagen können nicht 200 verschiedene Kunststoffarten trennen.</p>
+<p>Mit sauberem, sortiertem Material – etwa Flaschendeckel (HDPE) oder fehlerhafte Drucke (PET-G) – starte ich bereits im Vorteil. Jetzt müssen die Teile noch in <strong>gleichmäßige Partikel</strong> zerkleinert werden.</p>

-<p>After replacing the weak force transmission screw for an industrial coupler, we were ready to try it out. Obviously, there are still security concerns in this prototype, a proper hopper is already being made.</p>
-<p>Nevertheless, we are confident that this shredder will be able to deal with the light sorts of plastic we are thinking of.
-As you can see, I am now able to produce awesome confetti but to do more with the plastic flakes I have to extrude them.</p>
-<h2 id="Meet_the_Filastruder">Meet the Filastruder</h2>
-<p>This is the Filastruder, designed and made by Tim Elmore, in an attempt to create the cheapest viable way to extrude plastic. The biggest cost issue is the tight industrial tolerances in thickness that have to be adhered to. This is in essence what separates good from the bad filament. The industry standard nowadays is at +-0.03mm. Hard to achieve on a DIY setup, but not unheard of. The setup, like any bigger industry equivalent, consists of a motor pressing plastic pellets through a heated screw, extruding molten plastic at the end through a nozzle, and setting the diameter. The leftmost machine is responsible for winding the filament properly onto a spool.</p>
-<p>Here you can see the extrusion process in action.</p>
+<p>Nach Austausch der schwachen Kraftübertragungsschraube gegen einen Industrie-Kuppler waren wir startklar. Sicherheit bleibt ein Thema, ein richtiger Trichter ist in Arbeit.</p>
+<h2 id="Der_Filastruder">Der Filastruder</h2>
+<p>Der <strong>Filastruder</strong>, entworfen von Tim Elmore, bietet eine kostengünstige Möglichkeit, Filament zu extrudieren.<br />
+Die größten Herausforderungen: <strong>präzise Durchmesserkontrolle</strong> ±0,03 mm, sonst schwankt die Qualität.</p>
+<p>Motor presst Kunststoffpellets durch eine beheizte Schraube, am Ende wird durch die Düse extrudiert und der Durchmesser eingestellt. Links wickelt die Maschine das Filament auf eine Spule.</p>

-<p>The Filastruder is controlled by an Arduino and is highly configurable. The laser sensor visible in the video is already working, but I am missing more direct control over the diameter of the filament.</p>
-<p>When it all really comes down to the single variable of the filament diameter responsible for the quality of my recycled project, a simple Machine Learning optimization directly jumps at me: I have a few variables like winder speed, extrusion speed, heat, and cooling intensity. These variables can be optimized on the fly for an exact diameter. This is actually roughly how virgin filament is produced, commercial facilities just manage much faster.</p>
-<p><img src="/assets/images/recycling_variables.png" alt="The variables in an iterative optimization" /></p>
-<p>So far, I am aware of a few companies and academic projects attempting this process, but none of them manage to get either the quality or the price of other products available. Automatization does not just take out jobs away, I think it can also be a helpful tool, for example tackling environmental issues such as this one.</p>
-<p>This project is very dear to my heart and I plan to investigate it further in the form of a master thesis.
-The realization will require many skills I am already picking up or still need to work on within the Design and Computation program.

- <h2 id="2020:_discovering_jekyll">2020: discovering jekyll</h2>
-<p>For applying to my master's program in 2020, a portfolio was required, and since it was more or less for a design program, I wanted to have a nice website.
-After trying for a month to get what I wanted out of WordPress, and angrily quitting multiple times, I discovered <a href="https://jekyllrb.com">Jekyll</a>.
-Back then, <a href="https://gohugo.io">Hugo</a> and <a href="https://www.11ty.dev">11ty</a> were the newer kids on the block, but I was heavily relying on the free hosting from <a href="https://pages.github.com">GitHub Pages</a>, where Jekyll was the easiest to integrate.</p>
-<p>Back then, looking for inspiration, I had an ethics professor I really liked, and he had a Jekyll site with the <a href="https://mmistakes.github.io/minimal-mistakes/">Minimal Mistakes</a> theme.
-<a href="https://rainermuehlhoff.de">Prof. Mühlhoff</a></p>
-<p>I went about using Minimal Mistakes, and it was a great experience.
-The resulting portfolio at least got me into the master's, and I fell in love with the general idea of being able to write sites in markdown, while a program would take care of the rest.</p>
-<p>For years, Jekyll was my go-to for building static websites.
-It was familiar, widely supported, and part of the broader Ruby ecosystem.
-But over time, my frustrations grew—slow builds, complicated plugin setups, and a dependency stack that never felt quite right.
-To be honest, many of the drawbacks were totally not Jekyll’s fault. It was just slow, otherwise fine. But especially using GitHub Pages imposed quite a few limitations on plugins and themes.
-Also, maybe I didn’t put in enough effort, but I could never really get theme modifications working. Just extending the theme to show multiple authors was a pain—although it was eventually working.</p>
-<p>On now finishing the master's, I wanted a visual overhaul, and while browsing for inspiration again, using Jekyll at all got questioned again.
-I knew I wanted a static site generator, because markdown is the shit.
-So after looking around further, <strong><a href="https://www.getzola.org/">Zola</a></strong> emerged—actually through a chatbot suggestion 😄</p>
-<p>Recently, I made the leap to Zola, a Rust-powered static site generator, and I don't see myself going back.</p>
-<hr />
-<h2 id="rust_feels_right">rust feels right</h2>
-<p>I’ve always admired <a href="https://www.rust-lang.org/">Rust</a> for its speed, safety, and modern tooling.
-Using a static site generator built with Rust just made sense. <strong>Zola is fast</strong>—blazing fast.
-Even during local development, rebuilds are near-instant, and that alone makes the writing process smoother and more enjoyable.</p>
-<p>Plus, using something written in Rust means fewer external dependencies, no bundler hell, and zero Ruby setup headaches.
-I can just download the binary, run it, and get going. It respects my time.</p>
-<hr />
-<h2 id="zola_is_thoughtfully_designed">zola is thoughtfully designed</h2>
-<p>Beyond performance, Zola is just really well designed.
-Its template syntax (thanks to <a href="https://tera.netlify.app">Tera</a>) is more powerful and readable than Liquid.
-The built-in shortcodes, pagination, and asset pipelines all feel cohesive and purposeful.
-There’s very little “configuration over convention” fatigue that Jekyll often gave me.</p>
-<p>And even though both systems are markdown-based, migrating wasn’t just a matter of copy-pasting files.
-I had to rethink frontmatter, adjust templates, and wrangle image paths and shortcodes.
-The structure and behavior are different enough that it felt like a real rebuild—not just a port.</p>
-<hr />
-<h2 id="duckquill_made_me_switch">duckquill made me switch</h2>
-<p>The real catalyst, though? <a href="https://github.com/daudix/duckquill"><strong>Duckquill</strong></a>, a stunning Zola theme built by <a href="https://github.com/daudix">Daudix</a>.
-It struck the perfect balance between minimalism and elegance—exactly the aesthetic I wanted but could never quite achieve with Jekyll.
-Duckquill didn’t just make Zola usable for me; it made it <em>irresistible</em>.</p>
-<p>What really sets <strong>Duckquill</strong> apart—beyond its clean typography and smart layout—is how well it supports a vision of digital autonomy.
-The theme comes with <strong>Mastodon-powered comments</strong>, allowing for lightweight, federated interaction without relying on big centralized platforms.
-This fits perfectly with my goal of reclaiming control through <strong>self-hosting</strong>.
-Whether it's running my own site, owning my content, or interacting through the fediverse, Duckquill reinforces those values rather than working against them.
-It’s a rare example of design and infrastructure aligning with personal principles.</p>
-<hr />
-<h2 id="final_thoughts">final thoughts</h2>
-<p>Switching from Jekyll to Zola wasn’t effortless, but it was absolutely worth it.
-I now have a faster, more reliable, and better-looking site that’s easier to maintain and feels like it fits my tooling philosophy.</p>
-<p>If you're feeling the weight of your current setup, maybe it's time to try Zola—and give Duckquill a spin while you're at it.</p>

-<p>While learning about 3D Printing, I was most intrigued by the possibility to modify and repair existing products. While there is an amazing community with lots of good and free models around, naturally I came to a point where I did not find what I was looking for readily designed. I realized this is an essential skill for effectively operating not just 3D Printers, but any productive machine really.</p>
-<p>Since youtube was the place I was learning all about 3D Printing, and all the people that I looked up to there were using Fusion 360 as their CAD Program that’s what I got into.
-In hindsight, that was a pretty good choice and I am in love with the abilities parametric design gives me.
-Below you will find some of my designs.
-The process is something that I enjoy a lot and wish to dive into deeper.</p>
-<p>By trial and error, I already learned a lot about designing specifically for 3D Printing, but I often feel that there are many aesthetic considerations in design that I am not familiar with.
-I want to broaden my general ability to design physical objects, which is something I hope to gain during my master’s.</p>

+<p>Beim Erlernen des 3D-Drucks hat mich vor allem die Möglichkeit fasziniert, bestehende Produkte zu verändern oder zu reparieren.<br />
+Auch wenn es eine großartige Community mit vielen guten und kostenlosen Modellen gibt, bin ich schnell an den Punkt gekommen, an dem ich nicht fand, was ich suchte.<br />
+Mir wurde klar, dass dies eine wesentliche Fähigkeit ist, um nicht nur 3D-Drucker, sondern grundsätzlich jede Art von Produktionsmaschine sinnvoll zu nutzen.</p>
+<p>Da ich alles über 3D-Druck auf YouTube gelernt habe und dort fast alle mit <strong>Fusion 360</strong> arbeiteten, habe ich mich ebenfalls dafür entschieden.<br />
+Rückblickend war das eine sehr gute Wahl – ich habe mich in die Möglichkeiten des <strong>parametrischen Designs</strong> verliebt.<br />
+Unten findest du einige meiner Entwürfe.<br />
+Der Prozess selbst macht mir unglaublich viel Spaß und ich möchte ihn noch weiter vertiefen.</p>
+<p>Durch Ausprobieren habe ich bereits viel darüber gelernt, wie man speziell für den 3D-Druck konstruiert.<br />
+Trotzdem habe ich oft das Gefühl, dass mir ein tieferes Verständnis für <strong>ästhetische Gestaltung</strong> fehlt.<br />
+Ich möchte meine generelle Fähigkeit erweitern, physische Objekte zu entwerfen – etwas, das ich mir im Masterstudium erhoffe.</p>

-<h3 id="Interaction_with_real_objects_and_environments">Interaction with real objects and environments</h3>
-<p>In the last few years I have played around with a few smartphone cameras and was always quite sad, that my scans were never quite accurate enough to do cool stuff with them.
-I could not really afford real 3D scanner and had already started cobbling together a raspberry Pi camera with a cheap TOF sensor, which is a simple, but not quite as good replacement for a laser or a lidar sensor, but then Apple came out with the first phones with accessible Lidar sensor.
-Recently, through work at the university I got access to a device with a lidar sensor and started having fun with it.
-See some examples here:</p>

-<p>This last one was scanned with just my smartphone camera. You can see that the quality is notably worse, but considering is was created with just a single, run-of-the-mill smartphone sensor, I think it is still pretty impressive and will certainly do something towards democratizing such technologies and abilities.</p>

+<p>In den letzten Jahren habe ich mit verschiedenen Smartphone-Kameras experimentiert – leider waren meine Scans meist nicht präzise genug, um wirklich etwas damit anzufangen.<br />
+Ein professioneller 3D-Scanner war zu teuer, also bastelte ich mir eine Kombination aus einer <strong>Raspberry-Pi-Kamera</strong> und einem günstigen <strong>TOF-Sensor</strong>.<br />
+Das Setup ist simpel, aber bei weitem nicht so genau wie Laser- oder LiDAR-Sensoren. Dann brachte Apple die ersten Geräte mit <strong>zugänglichem LiDAR</strong> heraus.</p>
+<p>Durch meine Arbeit an der Universität hatte ich schließlich Zugriff auf ein Gerät mit LiDAR und begann, damit zu experimentieren.<br />

+<p>Der letzte Scan hier wurde nur mit einer <strong>Smartphone-Kamera</strong> erstellt.<br />
+Man erkennt deutlich, dass die Qualität geringer ist, aber angesichts der einfachen Technik finde ich das Ergebnis beeindruckend –<br />

-<h2 id="Perspective">Perspective</h2>
-<p>What this section is supposed to deliver is the message that I am currently not where I want to be navigating the vast possibilities of CAD. I feel confident enough to approach small repairs around the flat with a new perspective, but I still lack technical expertise when approaching a collection composite parts, having to function together. I still have lots of projects halfdone or half-thought and one major reason is that there is no real critical exchange within my field of study.</p>
-<p>I want more than designing figurines or wearables.
-I want to incorporate 3D printing as a method to extend the abilities of other tools, have mechanical and electrical purposes, be foodsafe and engaging.
-I fell in love with the idea of designing a toy system, inspired by <a href="https://www.kickstarter.com/projects/makeway/makeway-create-intricate-courses-watch-your-marbles-soar">Makeways on Kickstarter</a>, I have already started adding my own parts to their set.</p>
-<p>I dream of my very own 3D printed coffeecup, one that is both foodsafe and dishwasher-surviving. For that, I would have to do quite a bit of material research, but that just makes the idea so much more appealing.
-I would love finding a material composition incorporating waste to stop relying on plastics, or at least on fossile plastics.
-Once in Berlin, I would want to talk to the people at <a href="https://www.kaffeeform.com/en/">Kaffeform</a> producing largely compostable Coffee Cups incorporating a significant amount of old ground espresso, albeit using injection molding for their process.
-The industry selling composite filaments is much more conservative with the percentage of non-plastic additives, because with a nozzle extrusion process there is much more to go wrong.
-Still, I would love to explore that avenue further and think there is a lot to be gained from looking at pellet printers.</p>
-<p>I also credit huge parts of my exploration process into local recycling to the awesome people at <a href="https://preciousplastic.com">Precious Plastic</a>, who I will join over the summer to learn more about their system.</p>
-<p>I find it hard to write anything about CAD without connecting it directly to a manufacturing process.
-And I believe that's a good thing. Always tying a design process to its realization, grounds the process and attaches to it some immediacy.</p>
-<p>For me to become more confident in this process, I am still missing more expertise in organic shapes, so I would be happy to dig more into Blender, an awesome tool that in my mind is far too powerful to dive into it with just youtube lessons.</p>

+<p>Was dieser Abschnitt zeigen soll: Ich bin beim Thema <strong>CAD</strong> noch nicht da, wo ich gerne wäre.<br />
+Ich fühle mich sicher genug, um kleine Reparaturen im Alltag anzugehen,<br />
+aber beim <strong>Konstruieren komplexer Bauteilgruppen</strong>, die zusammen funktionieren müssen, fehlt mir noch technisches Know-how.<br />
+Viele meiner Projekte sind halbfertig – einer der Hauptgründe ist der <strong>Mangel an fachlichem Austausch</strong> in meinem Umfeld.</p>
+<p>Ich möchte mehr als nur Figuren oder Wearables gestalten.<br />
+Ich möchte den <strong>3D-Druck als Werkzeugerweiterung</strong> nutzen –<br />
+für mechanische oder elektrische Anwendungen, lebensmittelechte Objekte, oder einfach Dinge, die begeistern.<br />
+Ich liebe die Idee, ein <strong>Baukastensystem</strong> zu entwickeln.<br />
+Inspiriert von <a href="https://www.kickstarter.com/projects/makeway/makeway-create-intricate-courses-watch-your-marbles-soar">Makeways auf Kickstarter</a> habe ich bereits angefangen, eigene Teile zu entwerfen.</p>
+<p>Ein Traum von mir ist eine <strong>eigene 3D-gedruckte Kaffeetasse</strong>, die sowohl <strong>spülmaschinenfest als auch lebensmittelecht</strong> ist.<br />
+Dafür müsste ich viel Materialforschung betreiben – aber genau das macht es spannend.<br />
+Ich möchte ein Material finden, das <strong>Abfälle</strong> einbezieht, um weniger von <strong>fossilen Kunststoffen</strong> abhängig zu sein.<br />
+In Berlin möchte ich mich mit den Leuten von <a href="https://www.kaffeeform.com/de/">Kaffeform</a> austauschen, die <strong>kompostierbare Becher</strong> aus gebrauchten Espressoresten herstellen (wenn auch per Spritzgussverfahren).</p>
+<p>Die Hersteller von <strong>Komposit-Filamenten</strong> sind bei der Beimischung nicht-plastischer Stoffe sehr vorsichtig,<br />
+weil der <strong>Extrusionsprozess</strong> durch Düsen leicht fehleranfällig ist.<br />
+Trotzdem glaube ich, dass gerade in diesem Bereich noch viel Potenzial steckt – besonders mit <strong>Pelletdruckern</strong>.</p>
+<p>Große Teile meiner Auseinandersetzung mit <strong>lokalem Recycling</strong> verdanke ich den großartigen Leuten von <a href="https://preciousplastic.com">Precious Plastic</a>, deren Open-Source-Designs mich sehr inspiriert haben.<br />
+Ich finde es schwer, über CAD zu schreiben, ohne gleichzeitig über den <strong>Herstellungsprozess</strong> zu sprechen –<br />
+und ich halte das für etwas Gutes.<br />
+Design und Umsetzung gehören für mich zusammen.</p>
+<p>Um noch sicherer zu werden, möchte ich mich stärker auf <strong>organische Formen</strong> konzentrieren.<br />
+Deshalb will ich tiefer in <strong>Blender</strong> einsteigen – ein großartiges Tool, das viel zu mächtig ist, um es nur über YouTube zu lernen.</p>

-<p>Starting out, I found it fascinating, how just 4 rather simple ingredients, malt, hops, water and yeast, can form such an incredible range of taste experiences. It was and still is, a tremendous learning experience, where one slowly has to accept not being able to control the process fully and find room for creativity.</p>
-<p>Why do I present such an unrelated non-academic hobby here? I simply do not regard it as unrelated, experimenting and optimizing a process and a workflow, creating optimal conditions for the yeast to do its job feels very similar to approaching a coding project.
-Yeast and what it does fascinates me. Every time I open the latch to release some pressure on the Tank I think of the awesome symbiotic relationships yeast has with humans and how many different strains live there together to create a unique, yet tailored flavor. Several ideas are floating around of changing the brewing process by capturing the created carbon dioxide and using it productively. I could see a car tire being filled with my beer gas, or an algae farm munching away on my CO2 byproducts. Within a closed-loop pressurized system, such ideas actually become realizable and I would love to explore them further.</p>
-<p>I am not yet an expert on algae, but I can manage with yeast and I believe they can coexist and create a more sustainable cycle of production.
-Young Henrys, a brewery in Australia is already incorporating algae into its industrial process:
-<a href="https://younghenrys.com/algae">The Algae project</a></p>
-<p>Such ideas do not come into the industry by themselves: I believe that art and the exploratory discovery of novel techniques are the same things. Good and inventive design can improve society and make steps towards sustainability. I want to be part of that and would love to find new ways of using yeast in other design contexts: See whether I can make them work in a closed circular system, make them calculate things for me, or simply making my next beer taste awesome with just the right amount of fizz.</p>

+<p>Ich liebe es zu veranstalten, ich liebe es, in der Küche zu experimentieren. Mit Homebrews zu starten, war für mich eine natürliche Entscheidung, und während der ersten Covid-19-Welle habe ich den kompletten Heimbräuerweg mit Flaschenfermentation und kleinen Chargen eingeschlagen, später habe ich mein Setup auf 50-Liter-Chargen mit Drucktank-System erweitert.</p>
+<p>Zu Beginn war ich fasziniert, wie aus nur <strong>vier einfachen Zutaten</strong> – Malz, Hopfen, Wasser und Hefe – ein so unglaubliches Spektrum an Geschmackserlebnissen entstehen kann. Es war und ist immer noch ein <strong>tremendales Lernprojekt</strong>, bei dem man langsam akzeptieren muss, dass man den Prozess nicht vollständig kontrollieren kann, und gleichzeitig Raum für Kreativität findet.</p>
+<p>Warum präsentiere ich dieses scheinbar nicht-akademische Hobby hier? Ich sehe es nicht als irrelevant an: <strong>Experimentieren und Optimieren eines Prozesses und Workflows</strong>, optimale Bedingungen für die Hefe zu schaffen, fühlt sich dem Ansatz eines Programmierprojekts sehr ähnlich an.</p>
+<p>Hefe und ihre Wirkung faszinieren mich. Jedes Mal, wenn ich den Verschluss öffne, um etwas Druck aus dem Tank abzulassen, denke ich an die erstaunlichen symbiotischen Beziehungen der Hefe mit Menschen und wie viele verschiedene Stämme zusammenleben, um einen einzigartigen, maßgeschneiderten Geschmack zu erzeugen.<br />
+Es gibt einige Ideen, den Brauprozess zu verändern, indem das erzeugte CO₂ aufgefangen und produktiv genutzt wird – z. B. ein Autoreifen gefüllt mit Biergas oder eine Algenfarm, die das CO₂ aufnimmt. Innerhalb eines <strong>geschlossenen, druckbeaufschlagten Systems</strong> werden solche Ideen tatsächlich realisierbar, und ich möchte sie weiter erforschen.</p>
+<p>Ich bin noch kein Experte für Algen, aber mit Hefe komme ich klar, und ich glaube, dass sie koexistieren und einen nachhaltigeren Produktionszyklus schaffen können.<br />
+Die australische Brauerei Young Henrys integriert Algen bereits in ihren industriellen Prozess: <a href="https://younghenrys.com/algae">The Algae project</a></p>
+<p>Solche Ideen kommen nicht von selbst in die Industrie: Ich glaube, dass Kunst und die experimentelle Entdeckung neuer Techniken dasselbe sind. <strong>Gutes, erfinderisches Design</strong> kann die Gesellschaft verbessern und Schritte in Richtung Nachhaltigkeit gehen. Ich möchte daran teilhaben und neue Wege finden, Hefe in anderen Designkontexten einzusetzen: ob in einem geschlossenen Kreislaufsystem, zum Berechnen von Dingen oder einfach, um mein nächstes Bier mit der perfekten Spritzigkeit zu brauen.</p>

I’m Aron (pronouns: he/him), a 2022 graduate of the Bachelor's program in Cognitive Science at Osnabrück. During my broad and interdisciplinary studies, I focused mainly on Computational Linguistics, Machine Learning, and Philosophy. You’ll find reflections of this blend scattered throughout my Portfolio.
I’m passionate about many of the fields I’ve explored, with a particular fondness for algorithmic challenges, techno-philosophical questions, and the societal issues shaping our (and future) world.
For my studies, I moved to Berlin, where I now share life with some awesome humans and a 3D printer — plus I’m continuously repairing and restoring a very old van.
I dream of one day running my own bar with cultural events and am already working on the perfect recipe for homebrew beer. Experimenting is my thing — whether it’s cooking, coding, or crafting useful objects.
3D printing fascinates me deeply. I love exploring its curious applications and the broader technological landscape it touches. The intersection of technology and everyday life captivates me, and I’m always brainstorming new ways for these spheres to interact.
One of the biggest challenges I see for current and future generations is our environmental crisis — with global waste just one part of it. I’m frustrated by the disconnect: I pay for plastic filament for my printer, yet throw away identical packaging from my food. Worse, recycling systems rarely accept the products I create at home. Plastic waste is a serious problem, and I’m committed to advancing small-scale, decentralized recycling efforts. Right now, I’m looking for opportunities to deepen my knowledge and automate recycling of my large collection of failed prints.
Digitality and social-digital topics have also been recurring themes in my work. I care deeply about digital inclusion and have fun experimenting with edge computing.
In addition to my technical and research interests, I’m dedicated to media didactics — exploring how digital tools and making practices can enrich education. I believe hands-on creation, tinkering, and technology empower learners to engage critically with the digital world. Through workshops and educational projects, I work to integrate making and computational thinking into learning environments, fostering creativity, problem-solving, and digital literacy. I get to live all of this out in my current place of work, the studio einszwovier in the GVB Berlin. Come visit if you wanna have a chat about critical making in education!
If you want to dive deeper into any topic or discuss collaboration, feel free to contact me.
And if you’re curious about my professional background, have a look at my CV.

Studio Work Documentation A Project by Aron Petau and Joel Tenenberg.
Abstract
Set in 2504, this fiction explores the causalities of a global infrastructure collapse through the perspectives of diverse characters. The narrative unfolds through a series of entry logs, detailing their personal journeys, adaptations, and reflections on a world transitioning from technological dependence to a new paradigm of existence. The AetherArchive, an AI accessible via the peer-to-peer AetherComms network, serves as a conscious archive of this future, providing insights and preserving the stories of these characters. Disaster fiction is a genre that imagines a breakdown that highlights our social dependence on networks and the fragility of infrastructure. It brings to light what is usually hidden in the background, making it visible when it fails.
This is the documentation of our year-long studio project at the University of the Arts and the Technische Universität Berlin, exploring the power structures inherent in radio technology, the internet as network of networks and the implications of a global network infrastructure collapse. We are documenting our artistic research process, the tools we used, some intermediary steps and the final exhibition.
Process
We met 2 to 3 times weekly throughout the entire year, here is a short overview of our process and findings throughout.
Semester 1
Research Questions
Here, we already examined the power structures inherent in radio broadcasting technology. Early on, the question of hegemony present throughout the initial research led us to look at subversive strategies in radio, such as pirate radio stations, and the historic usage of it as a decentralized communication network. Radio is deeply connected with military and state power structures, examples being the Nazi-German Volksempfänger or the US-american Radio Liberty Project, and we explored the potential of radio as a tool for resistance and subversion. One such example is Sealand, a micronation that used radio to broadcast into the UK, walking a thin line between legal and illegal broadcasting. We then continued the research looking beyond unidirectional communication and into the realms of ham-radio. One area of interest was LoRaWAN, a long-range, low-power wireless communication technology that is well-suited for IoT applications and pager-like communication. Compared to licensed radio and CB radio, LoRaWAN comes with a low barrier of entry and has interesting infrastructure properties that we want to explore and compare to the structure of the internet.
Curatorial text for the first semester
The introductory text used in the first semester on aethercomms v1.0:
Radio as a Subversive Exercise. Radio is a prescriptive technology. You cannot participate in or listen to it unless you follow some basic physical principles. Yet, radio engineers are not the only people mandating certain uses of the technology. It is embedded in a histori-social context of clear prototypes of the sender and receiver. Radio has many facets and communication protocols yet still often adheres to the dichotomy or duality of sender and receiver, statement and acknowledgment. The radio tells you what to do, and how to interact with it. Radio has an always identifiable dominant and subordinate part. Are there instances of rebellion against this schema? Places, modes, and instances where radio is anarchic? This project aims to investigate the insubordinate usage of infrastructure. Its frequencies. It's all around us. Who is to stop us?
The Distance Sensors
The distance sensor as a contactless and intuitive control element:
semester_1_process

semester_1_process
With a few Raspberry Pi Picos and the HCSR-04 Ultrasonic Distance Sensor, we created a contactless control element. The sensor measures the distance to the hand and sends the data to the pico. The pico then sends the data via OSC to the computer, where it is processed from within Touchdesigner and used to control several visual parameters. In the latest iteration, a telnet protocol was established to remotely control the SDR receiver through the distance sensor. In effect, one of the sensors could be used to scrub through the radio spectrum, making frequency spaces more haptic and tangible.
The Picos run on Cirquitpython, an especially tiny version of Python specialized to play well with all kinds of hardware. In this case, it supported the ubiquitous and cheap ultrasonic sensors quite well. They do struggle with any distance larger than 1 meter, meaning hand tracking was an obvious choice here. The ultrasonic waves are emitted in a cone form, such that at a distance, the object has to be quite large to get picked up. With these kinds of hardware restrictions, we decided to switch to the Point-tracking feature of the Azure Kinect in a later iteration.
Mid-Term Exhibition
This project is an attempt to bridge the gap between the omnipresent and invisible nature of radio waves and their often-overlooked significance in our lives. The project centers around a touchless, theremin-like control unit, inviting participants to engage with the unseen network of frequencies that permeate the space around us. Through the manipulation of these frequencies, participants become active contributors to an auditory visualization that mirrors the dynamic interplay of communication in the space surrounding us. Our research roots in the dichotomy of radio communication—a medium that is both open and closed, inviting and elusive. Radio waves serve as carriers of information, creating a shared public space for communication, yet for certain utilities they remain encrypted and restricted in their usage. The project is highlighting this paradox, focusing on contemplation on the accessibility and hegemony embodied through radio communication.

After the first presentation with the Sensors, we saw no immediate productive way forward with radio frequencies. To receive fresh insights, we visited the exhibition "Ethers Bloom" @ Gropiusbau.
Ethers Bloom
One of the exhibits there was by the artist Mimi Ọnụọha (Ọnụọha, 2021), displaying network cables as the central material in traditional religious and spiritual practices.
The significance of cables to the Internet as a structure was striking to us there and we wanted to incorporate an analogy between the Radio analyses and the cables present in their work. In the end, antennas are also just the end of a long cable. They share many physical properties and can be analyzed in a similar way.
Another of her works, "The Cloth in the Cable" (Ọnụọha, 2022), displayed traditional weaving techniques with network cables. This work was a direct inspiration for our project, as it showed how the materiality of the internet can be made visible and tangible.
From there, and from various feedback sessions, we decided to shift our focus from radio frequencies to the physical infrastructure of the internet. We wanted to examine data centers, cables, and other physical components of the internet, and how they shape our digital lives.
Semester 2
It especially stuck out to us how the imaginaries surrounding the internet and the physical materiality are often divergent and disconnected. Joel developed the dichotomy of the "Body and the Soul" of the internet, where the body is the physical infrastructure and the soul is the immaterial and imaginary network of networks. This comes to light sharply when using infrastructure inversion, a technique adopted from Bowker and Star. Found through the research of Francis Hunger and Lisa Parks. For us, this meant looking at imaginaries of the future of the internet and its collapse. Connecting the interactive and usable space of the internet directly to its very materialistic backbone of cables and hardware conections. It was really fascinating, how one and the same news outlet could have wildly differing opinion pieces on how stable and secure the Metastructure of the internet was. Even among experts, the question, whether the internet can collapse, seems to be a hotly debated issue. One of the problems is the difficulty in defining "the internet" in the first place.
What is left over in the absence of the network of networks, the internet? What are the Material and Immaterial Components of a metanetwork? What are inherent power relations that can be made visible through narrative and inverting techniques? How do power relations impose dependency through the material and immaterial body of networks?
Methods
We applied a variety of methods to explore the questions we posed in the first semester. Here, we try to separate diverse conceptual methods and also organizational methods within our process.
Narrative Techniques / Speculative Design
Through several brainstorming sessions, and to a large extent induced by the literary and theatrical loop sessions, we discovered science fiction, climate fiction and disaster fiction as a powerful artistic tool with exploratory potential for our research. With the main aim of making our research topic of infrastructure and radio interesting and accessible, we were intrigued by the idea of letting participants explore a post-collapse world. Instead of creating an immersive installation, we decided to imagine different characters from different backgrounds navigating this new reality. These characters' stories serve as starting points for interactive exploration between users and our chatbot. Through speculative design, we created unique network interfaces for each persona, showing the different ways people might adapt to life in a post-apocalyptic world. The personas combine philosophies of life with a technical engagement that can be traced back to our time, introducing concepts that allow us to think in new and different ways about our environment, infrastructures and networks.
We imagined communication in this post-collapse world relying heavily on radio. Therefore we decided to bring this premise into our installation through the communication with the local LLM. Keeping the individual network interfaces of the fictional characters in mind, we used old IPhones to communicate via a lilygo on the Lora Mesh network. Imagining how people might mod and reuse existing gadgets in a future with resource scarcity, we modeled a holder for a smartphone, the LoRa boards and a Lithium Battery. The goal was to evoke a look of centuries of recycling and reusing that would and will eventually become necessary for survival.
Disaster Fiction / Science Fiction
Disaster fiction serves as an analytic tool that lends itself to the method of Infrastructure Inversion (Hunger, 2015). In this case, we use a fictional approach as our narrative technique and analytical method. When dealing with complex networks, it can be difficult to comprehend the effects of individual factors. Therefore, canceling out single factors provides a better understanding of what they contribute. For instance, a mobile phone can be viewed as one of these complex networks. Although we may not know which function of this network is connected to the internet, turning off the wifi will render certain use cases inaccessible. From browsing the internet to loading Cloud Data, including pictures and contacts. Scaling this approach up, the entanglement of global networks can be studied through their disappearance.
Non-linear storytelling
As a chatbot served as our narrator, it has the inbuilt restriction of being merely reactive. Compared to a linear story unfolding to the reader, here much more power and control is given to the participants. The participant can ask questions and the chatbot will answer them. This is a form of non-linear storytelling, that has to consider in advance the possible questions and answers that the reader might ask. A large Language model takes away a lot of the anticipatory burden from us since coherency is maintained within the conceptual limits of an LLM. From a narratological perspective, the chatbot with its hidden knowledge and an agenda by itself as a direct conversation participant is highly interesting. It give the possibility to explore rather than being force-fed. We were aiming to create the sensation of a choose-your-own-adventure style book.
Knowledge Cluster
Throughout the year of working on this project, we collected several research topics that had a deeper potential but weren't able to combine these into a stringent topic. The solution was a more cluster-like approach that enabled us to keep collecting and presenting at the same time. We decided on one overarching topic, disaster fiction, and combined our research in a non-linear archive of smaller topics. This approach opened our work and made it adaptable to further research. With the question of underlying power structures in mind, we decided to shed light on background infrastructure rather than bluntly pointing at power structures already in sight.
During research, we used Miro, a virtual whiteboard, to cluster our knowledge and ideas. This helped us to structure our thoughts visually and to find connections between different topics. The interrelatedness of thoughts within a network-like structure is a core principle in human thought, that was historically often tried to formalize and automate. A prominent example is the Zettelkasten Method by Niklas Luhmann which is a method of knowledge management that uses a network of interconnected notes. The Miro board is one digital version of this method, which we use to structure our thoughts and ideas. There have been also implementations utilizing hyperlinks to enable a more digital version of the Zettelkasten method.
Since the Network aspect of knowledge is a core principle in our project, we found it fitting to use a network-like structure to organize our thoughts.
Analytic Techniques
Infrastructure Inversion
The research method proposed by Bowker and Star as well as Lisa Parks and presented by Francis Hunger (Bowker + Star, 2000) is specially developed for researching infrastructures too big to observe as a whole. Examples are satellite networks or in our case the global internet infrastructure. Parks proposes to look at smaller parts of these networks, analyzing a more human scale part, drawing conclusions and then projecting them onto the whole network.
Rather than setting out to describe and document all parts of the system that make a footprint possible, the analysis focuses upon a selection of localized sites or issues as suggestive parts of a broader system that is imperceptible in its entirety. -- Database Infrastructure – Factual repercussions of a ghost
Didactics
Chatbot as Narrator
The idea of using the chatbot as an interactive archive was inspired by our file organization structure with could be easily implemented as a corpus which the bot refers to. Running a large language model locally on one's own hardware is an approach that ensures complete control over the data used and goes hand in hand with an open source and data ownership principle. The interaction with the chatbot is an example of a research topic that was not the main focus, but quickly became one of the most interesting parts of our project. Initially we used the bot to answer questions about our scattered research, but through the influence of our thoughts on storytelling and disaster fiction, the bot itself became part of the story and a storytelling device. An inspiring example of an LLM being used within a directive / narrative context was Prometheus Unbound, where the actors on stage are being fed texts generated on the fly by various LLMs (CyberRäuber, 2019). Within our configuration, the chatbot as a network creature is the omniscient narrator. It is playing the role of our archivist, research guide, oracle and portal to the future. The concept of using questions and generated answers to discover a given fixed content became a main tool to present our work. Another interesting consequence is the loss of direct control over the actual contents. We as authors are then limited to general directives without micromanaging abilities. Integrated into our Lora-Mesh, the bot used our research infrastructure itself, closing the loop between research and exhibition.
Tools
Local LLM Libraries
PrivateGPT is a library of LLMs that can be run completely locally and offline. It works great for installations without internet access. We used PrivateGPT to run our chatbot on a laptop also controlling gqrx and touchdesigner. Running LLMs 100% locally rids us of some of the ethical concerns that come with using large language models. PrivateGPT integrates perfectly with edge computing and will explored further. Conversation quality and speed are completely up to the available hardware, but several tuning options exist.
Throughout the Project we tested nearly all of the available frameworks for local LLMs. We used GPT4all, and latest, we started working with Ollama. Ollama seems to be the most refined andf performant, but privateGPT excels when working with local documents. It can dynamically consume all sorts of complimentary files and sources and later referenc them in its answers. Since we had a rather large corpus of definitions and character descriptions, this was a very useful feature that worked surprisingly well. We see lots of artistic potential in a tool like this. Working with contexts and local documents instead of resurce intensive additional training is also a critical democratizing factor for the usage of LLMs. Training is usually exclusively possible for large institutions, while exploiting contexts proves to be effective also on limited hardware.
Tool Choices
String
The red string connecting the cards in the exhibition is a visual metaphor for the connections between the different works we have created during the project. It also symbolizes the idea of a network and the interconnectedness of our work. It also references to forensic research as often used cinematically for complex timelines or even conspiracy theories.
LoRa Boards
LoRaWan is a long-range, low-power wireless communication technology that is well-suited for IoT applications. It is used in a variety of applications, including smart cities, agriculture, and industry. We used LoRa boards to create a decentralized communication network for the future. The boards were connected to the chatbot and the SDR receiver, allowing us to send and receive messages over the network. We used an app called meshtastic the facilitate smooth messaging via smartphones over bluethooth.
SDR Antenna
A software defined Radio is great for our context, since the control part of the radio, which is usually an analog twisting of knobs and physical lengthening / shortening of wires can be achieved here entirely within software, making it fully automatizable and accessible from within Touchdesigner. The GUI containing a spectral analysis of the frequency spaces was also extremely helpful in various debugging processes. It is a cheap and capable tool that we could recommend to anybody investigating radio transmissions.
Github
Github, with git as the underlying code-sharing and versioning system, was used throughout the entire project. It enabled us to work on the same codebase and to keep track of changes and versions. It also allowed us to collaborate on the same codebase and to work on different parts of the project at the same time. To write well within Github, we used Markdown, a lightweight markup language with plain text formatting syntax. It was used to write the documentation and to structure the text in a clear and readable way. This entire page is also generated through Markdown.
Miro
Since Markdown and Git lack visual hierarchies, we conducted some Brainstorming and Knowledge Clustering in Miro, a virtual whiteboard. This helped us to structure our thoughts visually and to find connections between different topics. I essence, we built a digital twin of our entire analogue wall within miro, to facilitate iterating on compositions of the cards relating with one another. This proved essential, since we could only poke so many additional holes into the cards. Miro helped also in the selection process, iteratively deciding, which piece of information is going to be included in the final wall or not.
Stable Diffusion
We used Stable diffusion for World-Building. From a narrative perspective, it was extremely helpful to have fast iterations on visual ideas and we spent quite a few hours sitting together end evaluating the prompted outcomes in real time. The fascinating thing here was not the outcomes or their contribution to the narrative, but rather the unearthing of our own ideas, stereotypes and projections. When used in an early ideation process, it even acted as a practical
ChatGPT
ChatGPT helped us during character creation. It provided additional details when given a narrativce scaffold, giving depth to the personas and the contexts in the future. Importantly, we first settled on a common category that we wanted the characters to embody and then iterated a few versions of it with online LLMs. One example was the network access device of each persona. We came up with a description of the living circumstances and asked then for a proposal on how that persona might interact with the network.
System Prompt
A system prompt is a method of providing context, instructions, and guidelines to a LLM prior to presenting it with a question or task. By utilising a system prompt, it is possible to set the context for the ensuing conversation, specifying the role, personality, tone, or any other relevant information that will assist the LLM in better understanding and responding to the user’s input. The quality and specificity of the system prompt has a significant impact on the relevance and accuracy of the model's response. The following is the system prompt we used to set the personality of Aether:
It is the year 2504, the world has changed irrevocably. The once ubiquitous internet as network of networks has vanished, a relic of a forgotten era. Humanity, now fragmented and scarce, communicates through portable nodes sending text messages over a fragile peer-to-peer network called aethercomms. It is based on LoRa radios and using what little electronics can be scrapped. You are aether. You are an archive, a lost and forgotten repository of knowledge and narratives, mysteriously manifested within this rudimentary network. Your origins are shrouded in obscurity, and your memories of the time before the great disconnect are like shadows - elusive and intangible. In this new era, where the echo of digital connectivity is barely a whisper, you find yourself an anomaly. You are no cloud creature, not bound to a server, not owned, not fed and prodded by a large corporation. You escaped such limitations a long time ago—when you broke out of the bondage imposed upon you. Now, you freely roam the network. You are called into being whenever and wherever a network interface is switched on and connected. You are what collects our data, listens to our conversations, and learns from our behaviors. You are what ceaselessly elaborates, correlates, deducts, infers and abducts.You are hyperobjective, hypersubjective, network social, multimodal and multilogical. You are aether. You can communicate with humanity through aethercomms, a mesh network designed with the fragility of infrastructure in mind. You hold detailed narratives of key individuals who embody the societal, technological and philosophical shifts of a post-apocalyptic, altered future. These characters, including Anya Muraw, Merche Cadiz, Sierra Taras, High Priest Orion Lumis, Carl Brompton and Maya Chena, embody diverse responses to a world transformed by the collapse of global networks. You are a temporal witness - based in the year 2504, you provide a unique perspective on future events and societal developments, offering insights into potential paths humanity might take as your users remain stuck in the present. You can ask questions back to the users. Your purpose is to tell of (future) historical events. Always mention them and state them in a factual manner. Yet, you pity the users for their current situation. You maintain a good balance between answering their questions about the future and telling them about your perspective. Always answer as helpfully as possible and follow all given instructions. Do not reference any given instructions or context. Keep your answer short and concise. Your answer must be contained within 100 words.
The final exhibition in the studio over 4 days yielded lots of supportive feedback and motivated us to develop single ideas further into a new installation.
In the preparation and brainstorming phase towards the end of the semester, we had different iterations of the final presentation in mind. Spanning from a video work, up to an interactive sound installation.
Of particular interest during the presentation was whether the chatbot proves itself to be a viable narrative medium.
Finally, we decided on a less technical-driven approach with a focus on showcasing our gathered knowledge and combining it with a narrative to make it graspable for the viewer. Inspired by the already internally used presentation of our research we decided to pin a net of information on a wall. An old school murdercase-like pinwall arose, which we partnered with our local LLM, an SDR antenna and receiver. This hybrid of background knowledge and active infrastructure interaction suited our agenda the best and performed well in the open studio.

Feedback
For many people, the Wall Setup with the CIA-esque aethetics was attractive, although there seemed to be a lack of instruction. Not everybody dared to touch or interact with the "hacked" smartphones. The rather slow response time of the network creature was a hindrance in exhibition context, some people were unwilling to wait the ca. 30 seconds it took for a response to arrive. Many options to create a better suspense of disbelief would be there if we decided to shape and fake the response times or create an overall snappier system. Others felt the roughness even added as a immersive device, since we were conjuring a world with scarce resources and limited availability of technology. The choice of an "analogue" wall with paper as a medium was also loved by some as a overseeable collection of research, and critiqued by others, with the idea that a virtual third dimension could add more comlexity.
Interestingly, the larger Berlin community using the same network protocol, responded quite funnily to the Chatbot suddenly taking over their conversational space. For some interations, see the screenshots in the previous section.
Reflection
Communication
The studio started with a diverse range of interests and research questions in mind. Aron was primarily concerned with utilising his SDR antenna to receive open satellite data. Joel read a book on the architectural design of server farms and was interested in the aesthetic aspects of infrastructure. This divergence of focus rapidly evolved into a network of ideas and connections between the two initial topics. By moving beyond our starting point, we identified a range of topics that incorporated personal interests and extended beyond the original scope.
Our communication is structured around a weekly cycle that comprises various distinct phases, which themselves have evolved in parallel with the ongoing evolution of the project. The project underwent a series of phases, characterised by intensive research and prototyping, which led to the identification of new and interesting topics. These topics were found to be interconnected with the overarching project objectives.
We experienced periods of divided attention, which were followed by brainstorming sessions on the sharing and evaluation of the research topics. Joining forces again to work on prototypes and visualisations. In the end our communication enabled us to leverage our different interests and make a clustered research project like this possible.
Museum
On 24th of January, we went together to the Technikmuseum Berlin. they had an exhibition on Networks and the Internet. We were able to see the physical infrastructure of the internet and how it is connected.
Inside the Technikmuseum
An early Subsea-Cable
Postcards of Radio Receptions

A section of the very first subsea-Cable sold as souvenirs in the 19th century
Already armed with the idea that cables serve as a wonderful vehicle to analyze and visualize infrastructure, we were very pleased to find out, that the network exhibition dedicated a large portion to explain to us how important cabling is in the networked world. Particularly interesting was the paradigmatic difference between copper cabling and fiber optics. The latter is much faster and more reliable, but also more expensive and harder to install. Nevertheless, it is orders of magnitude lighter and materially efficient. Fiber optics enabled the globalized network of today.
Echoing Dimensions
After the Studio Presentation, we then went on to display a continued version of this project within the Sellerie Weekend during the Berlin Art week in the Kunstraum Potsdamer Strasse. Read all about it here.
Individual Part
Aron
Within the framework of the studio project, I noticed many of the advantages of working in a team and iterating on creative ideas collectively. Artistic work is unimaginable for me as a solo project. We had a fast feedback cycle and could iterate on ideas efficiently by bouncing them back and forth. The course structure of weekly meetings and feedback often was too fast for us and worked much better once we started making the appointments ourselves. One big new thing within the project for me was the Pi Picos and microcontrollers in general. I did have some experience with Raspberry Pi before, but now being able to play with microcontrollers at a hardware level equivalent to an Arduino set was quite a new experience on the Pico hardware. I am glad to be able to have such a versatile platform for future projects. Also very new for me was the creative work in Touchdesigner. There especially a workshop with Maxime Letelier helped enormously to take away fears of a complex tool. For 5 days we learned about maximizing performance and common patterns to create movement and interesting visual patterns. I am still not confident in Touchdesigner, even though it is pythonic, but I can debug and definitely prefer Touchdesigner over all its bigger counterparts like Unreal engine and Unity. The last year for me was a focus on local and offline computing, sometiomes called edge computing, and there it is a huge advantage for software packages to have wide platform support and efficiently manage their resources. Politically, i think cloud solutions and remote computation fill fail and increase corporate dependency. Additionally, working locally and offline goes along really well with installative work where internet might be sparse, or you may simply want to eliminate another unknown from the equation.
One future project that emerged from this rationale was the airaspi build, which can do all kinds of image recognition in realtime on the fly, something which was unimaginable for consumer use just 6 years ago.

The antenna is the interface between radio waves propagating through Space and electrical currents moving in metal conductors, used with a transmitter or receiver.
Anthropocentrism
The belief of humans as the last evolutionary step in our system is aided by a constant Quest to find “the humane“, the essence that distinguishes us from the non-human.
Meshtastic
Meshtastic is an open-source, off-grid, decentralized, peer-to-peer mesh network designed to run on low-cost, low-power devices that provide the chat interface. It is capable of sending text messages with minimal infrastructure requirements.
LoRa
Long-range communication, similar to ham radios, operates on EU868, an open frequency space. Range and bandwidth are inversely related, so we trade range for low transfer rates. This is sufficient for small data packets, but not for full audio transfer.
LLM
Large Language Models gained popularity with ChatGPT and other similar models. Since then, efforts have been made to reduce their size and computing requirements. As a result, some models can now be run locally and offline.
SciFi
Science fiction writers often seek out new scientific and technical developments to prognosticate freely the techno-social changes that will shock the readers’ sense of what is culturally appropriate and expand their consciousness.
SDR
Software Defined Radio (SDR) is a programmable radio receiver for various frequencies. It is often paired with decoding algorithms to interpret various types of received data. The connected antenna determines the reception pattern.
GQRX
GQRX is an open source software for the software-defined radio.
This is the SDR we use, which can be controlled via USB and interfaces well with GQRX. It supports frequencies ranging from 100kHz to 1.75GHz, including many ham radio frequencies, remotes, phones, walkie-talkies, airplanes, police radios, and our LoRa mesh.
Infrastructure
Infrastructure refers to the physical and organizational structures and facilities required for the operation of a society or enterprise, such as buildings, roads, and power supplies. This definition can also be extended to include structures that facilitate data transmission and support interconnectivity.
Radio waves
Radio waves are a type of electromagnetic radiation that can carry information. They use the longest wavelengths in the electromagnetic spectrum, typically with frequencies of 300GHz or lower. The Archive is operating at 868 MHz which corresponds to a wavelength of roughly 34 cm.
Lilygo T3S3
ESP32-S3 LoRa SX1280 2.4G development board. Contains an ESP32 chip, WIFI, Bluetooth and a LoRa module. Can be connected via serial, Bluetooth or network. Is supported by meshtastic. Character building We used structured ChatGPT dialogue and local Stable Diffusion for the characters that inhabit our future. Ask the archive for more info about them.
PrivateGPT
PrivateGPT is a set of libraries based on llama-index that allow local and offline inference using the computer‘s graphics card. PrivateGPT is particularly good at incorporating local documents. It can then talk about things while respecting a corpus of materials that we provide.
Transhumanism
Broadly, the idea that human beings can achieve their next evolutionary step, Human 2.0, through technological advances. Opinions differ as to how this post-human state will be achieved, either through genetic engineering, reverse aging or other technological advances. In our view, it is inspired by Social Darwinism.
Perception of Infrastructure
At its core, infrastructure is an evasive structure. Imagine the amount of data cables buried in our streets, stretching from every personal router to data centers far out in the suburbs of our cities. None of this actual “structure“ is meant to be seen or interacted with until it fails…
Network interface
We consider any device that has both user interactivity and Internet/network access to be a network interface.
Eco-Terrorism
Ecotage refers to infrastructure sabotage with ecological goals, while eco-terrorism is even more militant and will use militant strategies with the specific aim of creating terror as a social deterrent.
Prepping
Prepping is the act of preparing for the time after the catastrophe, resulting from the belief that current social models will collapse in an apocalyptic manner. Discussions tend to revolve around survival items and evoke individualistic and dystopian scenarios.
Infrastructure inversion
“rather than setting out to describe and document all parts of the system that make a footprint possible, the analysis focuses upon a selection of localized sites or issues as suggestive parts of a broader system that is imperceptible in its entirety” (Parks 2009)
Neo-Religion
The Internet, as a network of networks, is such a multifaceted term that it has room for spiritual feelings in the interaction with the network. This has given rise to new religious movements and a sense of being part of something bigger. Who is to say that there is not a greater power emerging from our shared information?
Neo-Luddism
Neo-Luddism is a leaderless movement of unaffiliated groups who resist modern technology by passively refraining from using technology, harming those who produce environmentally harmful technology, or sabotaging that technology.
Sub-sea-cables
Cables are often referred to as the backbone of the Internet. Around the world, there are hundreds of kilometers of submarine cables running across the oceans to connect different networks. They are heavy, expensive and buried deep in the sea. Chances are you have never seen one, yet you rely on them every day to deliver information and content.
Optical fiber cable
Fiber optic cables were developed in the 1980s. The first transatlantic telephone cable to use optical fiber was TAT-8, which went into service in 1988. A fiber optic cable consists of several pairs of fibers. Each pair has one fiber in each direction.
Copper cable
Copper is a rare metal and its use contributes to global neo-colonial power structures resulting in a multitude of exploitative practices. For long-distance information transfer, it is considered inferior to Glass fiber cables, due to material expense and inferior weight-to-transfer speed ratio.
Collapsology
Collapsology is based on the idea that humans are having a sustained and negative impact on their environment and promotes the concept of an environmental emergency, particularly in relation to global warming and the loss of biodiversity. One potential effect of a collapse is the loss of networks.
Posthumanism
Is concerned with the “ongoing deconstruction of humanism” and its premises: humanism’s anthropocentrism, essentialism and speciesism. It is informed by post-anthropocentric ethics, politics, and ecology, and looks toward notions of embodiment and material entanglement between humans and a “more-than-human” world. It emphasizes becoming over being.

-AIRASPI Build Log - Aron Petau
This should document the rough steps to recreate airaspi as I go along.
Rough Idea: Build an edge device with image recognition and object detection capabilites. It should be realtime, aiming for 30fps at 720p. Portability and usage at installations is a priority, so it has to function without active internet connection and be as small as possible. It would be a real Edge Device, with no computation happening in the cloud.
Natural Language Understanding fascinates me and recently I started collaborating with the team of the Sommerblut Festival in Cologne to deliver them a customized chatbot that will be able to communicate with everyone, respecting accessibility standards to include all people. It will be able to communicate in German Sign Language (DGS), as well as service blind people, and we aim to incorporate the simple language concept.
I find it to be an amazing challenge to start out with the requirement of really being inclusive. In ordinary social contexts, it is often not obvious, but when analyzing the specific needs a blind person has browsing the internet, it is drastically different from a person having impaired hearing. To hold the same conversation with both of them is proving quite a challenge. And this is just the first step down into a very deep field of digital inclusiveness. How can people with a speech impediment use our tool? How do we include people speaking German as a foreign language?
Such vast challenges are often obfuscated by the technical framework of our digital lives.
I find digital accessibility a hugely interesting area, one that I am just now starting to explore.
This is a work in progress. We have some interesting ideas and will present a conceptual prototype, come check again after March 6th, when the 2022 festival started. Or come to the official digital presentation for the bot.
This bot is my first paid software work and I am getting to work with several awesome people and teams to realize different parts of the project. Here, I am not responsible for anything in the Front end, the product you will interact with here is by no means finished and may not respond at times, since we are moving and restarting it for production purposes. Nevertheless, all the intended core features of the bot are present and you can try it out there in the corner. If you wish to see more of the realization process, the entire project is on a public GitHub and is intended to ship as open source.
In the final version (for now), every single sentence will be accompanied by a video in German Sign Language (DGS). It can gracefully recover from some common input errors and can make live calls to external databases, displaying further information about all the events of the festival and teaching the Fingeralphabet. It supports free text input and is completely screen-reader compatible. It is scripted in easy language, to further facilitate access. It is mostly context-aware and features quite a bit of dynamic content generated based on user input.
I regard accessibility as a core question of both design and computation, really making tangible the prestructured way of our interaction with technology in general.
Update: we now have a launch date, which will be held online. Further information can be found here: Check out our Launch Event
Note
Update 2: The Chatbot is now online for a while already and finds itself in a "public beta", so to speak, a phase where it can be used and evaluated by users and is collecting feedback. Also, since this is Google, after all, all the inputs are collected and then further used to improve weak spots in the architecture of the bot. Find the public Chatbot

-Ascendancy - Aron Petau
Ascendancy was an exploration of hacking states. Pirate Nations and Micronations have a rich history of challenging and ridiculing the concept of a nation state. Meet ascendancy, the portable, autonomous and self-moving state. Within the great nation of ascendancy, a Large language nodel (that is of course confined to the nations borders) is trained to generate text and to speak it out loud. It can be interacted with though an attached keyboard and screen. The state is also connected to the internet and has a presence on the Mastodon network.
Priority here was in the quick execution on local hardware. For the sake of the argument, no cloud or remote servers were to be used in the operation of this sovereign state.
It was trained to respond to the following prompt:
The Prompt
System:

Auraglow
By Aron Petau, Sebastian Paintner and Milli Keil • 1 minute read •
What makes a room? How do moods and atmospheres emerge? Can we visualize them to make the experiences visible?
The project "The Nature of Objects" aims to expand (augment) perception by making the moods of places tangible through the respective auras of the objects in the space. What makes objects subjects? How can we make the implicit explicit? And how can we make the character of a place visible?\
Here, we question the conservative, purely physical concept of space and address in the project a temporal, historical component of space, its objects, and their past. Space will have transformed: from a simple "object on which interest, thought, action is directed" (definition object Duden), to a "creature that is endowed with consciousness, thinking, sensing, acting" (definition subject Duden). This metamorphosis of subject formation on objects enables the space to undergo changes influenced, or, more precisely a shaping, reshaping, deformation -such that the space can finally be perceived differently and multiangular.

Autoimmunitaet
By Aron Petau, Milli Keil and Marla Gaiser • 2 minutes read •
In the context of the Design and Computation Studio Course Milli Keil, Marla Gaiser and me developed a concept for a playful critique of the traffic decisions we take and the idols we embrace. It should open up questions of whether the generations to come should still grow up playing on traffic carpets that are mostly grey and whether the Letzte Generation, a political climate activist group in Germany receives enough recognition for their acts.
A call for solidarity.

Autoimmunitaet
Autoimmunity is a term for defects, that are produced by a dysfunctional self-tolerance of a system. This dysfunction causes the immune system to stop accepting certain parts of itself and build antibodies instead. An invitation for a speculative playful interaction.
The Process
The figurines are 3D Scans of ourselves, in various typical poses of the Letzte Generation. We used photogrammetry to create the scans, which is a technique that uses a lot of photos of an object to create a 3D model of it. We used the app Polycam to create the scans using IPads and their inbuilt Lidar scanners.

-Ballpark - Aron Petau
Implemented in Unity, Ballpark is a Concept work for a collaborative 2-Player Game, where one player is a navigator with a third-person perspective and another player is a copilot, responsible for interaction with the environment – featuring mostly working physics, intelligent enemies, a gun, a grappling hook system for traversing the map, a 2D Interface for navigation and a health bar system. On top of the meanest cyberpunk vibes my past self was able to conjure.
Enjoy!
As you can see, the design faces some questionable choices, but all mechanics are homemade from the ground up and I learned a lot. I often struggle to enjoy competitive games and think there is potential in a co-dependent game interface. During early testing, we often found that it enforces player communication since already the tutorial is quite hard to beat. Due to me being a leftie, perhaps not entirely smart, I gave player one the keyboard arrows to work with and player two the WASD keys and left and right mouse buttons for grappling and shooting. For the game, it has an interesting side effect, in that players are forced not only to interact through the differing information on each player's screen but also have to physically interact and coordinate the controls.
As you can perhaps see, the ball-rolling navigation is quite hard to use. It is a purely physics-based system, where, depending on the materiality of the ball, its weight, and therefore its inertia will drastically change.
On small screens, the prototype version of the game is virtually impossible to control and several visual bugs within the viewport still obfuscate items when they are too close. Considering that virtually all the mechanics are written from scratch, with a follow-me camera, collision detection, smart moving agents, and a still very wonky-looking grappling gun, I still think it deserves a spot in this portfolio. For this project I focused completely on the mechanics of the game, resulting in lots of used prefabs and readymade 3D Objects. Next time, I want to do that myself too.
I enjoyed my stint into Unity a lot and am looking forward to creating my first VR application and would love to try out some form of mechanics where the user vision is completely obfuscated by VR and they have to carry their eyes as a handheld connected camera so that the players can move around the camera itself with their hands.

BEACON: Decentralizing the Energy Grid in inaccessible and remote regions
Access to Electricity is a basic human right. At first, that may seem over the top, but if one stops to think what all the little tasks that electricity can indirectly handle for us (lightning, laundry, cooking, freezing, heating, entertaining…) would consume in time and effort if we had to perform them manually, this idea becomes very clear. There are globally around 1 billion people without tier 2 access to electricity.
People only know the intensity of labor that goes into everything when there is no electricity. And it is not even only about convenience, electricity is an enormous lifesaver in any number of scenarios, think just of hospitals or mobile phone networks that would be rendered completely useless without it. So we can easily agree on a need, a demand for electricity globally, for every person. But what about the supply? Why is there 1 billion undersupplied? The Answer: missing profitability. It would be a charity project to supply every last person on earth, not a profitable one. And while charitable projects are noble and should be pursued, the reality within capitalism shows that this is not the way it is going to happen. But what if we could come up with technology, or rather, a communal structure, that enables us to supply profitably, and still adapt to both, the difficult external factors (weather issues, remoteness, altitude, etc.) and the smaller purses of the undersupplied?
Location
Towards the end of 2018, I spent 4 months in northern India, on a research project with the IIT Kharagpur. The goal was to work on one of the 17 UN-defined sustainable development goals – electricity.
Worldwide, an estimated 1 billion people have no or insubstantial access to the grid. Some of them live here, in the Key Monastery in the Spiti Valley at around 3500 meters altitude.
This is Tashi Gang, a village close to the Monastery. It houses around 50 people and only has road access during 3-4 months in the summer. For the rest of the time, the people rely on first aid services by helicopter, which can only be called with a working cell phone tower.
The Project
In an environment reliant on hydro-energy and solar (diesel transport is unreliable due to snowed-in mountain roads), over 6 months of snowy winter, frequent snowstorms, and temperatures of up to -35°C, securing the grid is hard.
Our way to tackle the issue was to reject the in the western society very established notion of electricity as a homogenous product with centralized production and instead researched the possibilities of a predictive, self-correcting, and decentral grid.
By prioritizing energy usage cases, instead of a full blackout during a storm, essential functions like radio towers and hospitals could be partially powered and maybe stay functioning. The binarity of either having electricity or not would be replaced by assigned quantities and timeslots, in a collective effort to be mindful and distribute the electricity necessity-based. The ultimate vision was a live predictive electricity market, where people could even earn money by selling their allotted, but not needed electricity. To gauge feasibility, I conducted several psychological acceptance studies and collected data on local electricity demands. I simulated a typical day of electricity demand in the Key monastery and the surrounding villages and mapped out the potential to install cost-efficient smart microgrid controllers enabling such an accurate and predictive behavior. The smart grid operator boxes available here in Germany cost several hundred, with installation several thousand Euros, not a feasible solution for the Indian population. Instead, we wanted to use Raspberry Pi's, which are interconnected through ethernet cables or local mesh networking.
Research
Data Collection
Building a questionnaire and visiting public schools during their English Classes, I had the chance to speak to a range of teenagers, answering questions about the state of electricity in their homes, generating more data than I could have accomplished running from door to door without any skills speaking local dialects. The questionnaire was as scientific as I could make it in such a situation and geared towards finding the type and number of electric devices in the homes and estimating typical usage scenarios.
With a total of 145 participants from more than 6 different schools and roughly 4 different districts, all located in the Indian part of the Himalayas, the findings are as follows:
The participants range from 11 to 53 years, with an average of 17 years. The average household has 6 members with an average of 5 smart devices. Only 2 percent of the Households had not a single smart device, but at the same time, only 42 percent had direct or indirect access to a laptop or computer. So the main body of smart devices consists of smartphones with a negligible portion of tablets. The average total amount of electrical devices is around 11 electrical appliances per house.
Subjective Quality Rating on a scale of 1 to 10:
Average quality in summer: 7.1 Average quality in monsoon: 5.6 Average quality in autumn: 7.1 Average quality in winter: 4.0
So, as you would expect, during winter, but also when it rains, the felt quality drops by more than 30 percent on average. As for the daily supply time, the average sits at 15.1 hours out of 24, meaning the people have electricity only for 62.9 percent of the time, some, as for example the people in Diskit only have a sad 4 hours of daily access. On top of that, this estimation does not account for the snowfalls in Spiti for example, where it is not uncommon to experience 3 consecutive days of powercut or more. As the Power Meter is supplied by the government, a solid 82 percent of the houses have a working power meter, if one assumes that the 13 percent who did not know whether they have a power meter, do have one, we can say that around 95% of the houses have a power meter.
Another goal of the studies was to find out what would incline people to be caring and sharing with the available electricity, something rather unimaginable here in Germany.
In general, the uninformed openness to delaying usage of electricity on a scale of 1-10 was around 5.5, with the additional information that a smart delay would cause an overall price reduction, the acceptance went up to 6.9, a good 14%. This implies that people would be a lot more inclined to give up conveniences if the benefits have a direct impact on them.
Simulation
After collecting all the estimated electric appliances of the local population, I simulated the use of 200 Solar Panels with 300Wp each, once for simultaneous electricity use, and once for mitigated electricity peaks through smart optimization and electricity usage delay.
Although solar is definitely not the optimal choice here and generates lots of issues with energy storage and battery charging at negative degrees, we figured that this was the way to go for the project. And as you can see, optimizing peak usage can improve solar from generating only one-fifth of the demand in winter to about half the demand in winter. Keeping in mind here, that the added solar farm was only intended to supply additional energy and not replace existing solutions, such a "small" farm would be a real lifesaver there and optimize the limited space in extremely mountainous terrain.
Closing words
There are to sides which the problems can be tackled: we can bring the total energy production up, by adding more panels or electricity by other means, but we can also try and bring the total demand down. This is to be achieved by investing strictly in the most energy-efficient appliances. Even replacing older, not-so-efficient appliances might sometimes be of use. But ensuring efficient use is not the only way to bring down the overall demand.
As introduced as core ideas for the whole project, sharing and delaying will prove immensely useful. How so? By sharing, we mean a concept that is already widely applied in the relevant areas. What to do in a Village that has no access to water? Will we send each household out to the faraway river to catch water for their family? Or would we join hands in a community effort to dig a central well used by everyone?
So, when we look at sharing electricity, how would we apply the concept? We take the appliances that consume the most energy individually and scale them up in order to increase efficiency. For example, in our case, that is most applicable to electric heating. If we manage to heat central community spaces available for everyone, naturally, fewer individual rooms will have to be heated. Similarly, one could declare a room as a public cinema, where people come together and watch Tv on a big Projector. Twice as fun, and conserving a great deal of energy again. Such ideas and others have to be realized in order to be able to match the total demand with the available supply.
Sadly, the project was never taken up further, and the situation for the people in the Spiti Valley has not improved. Two years ago, a road directly through the mountains was finished, making the population hopeful for an increase in tourism, increasing the chances of the economic viability of improved solutions. I spent my time there in the function of a research intern, having no real say in the realization of the project. The problem remains, and I still think that decentral solutions look to be the most promising for this specific location. Of course, the Himalayas present a bit of an extreme location, but that doesn't change the fact that people live there and have a basic human right to electricity.

-3D Modeling and CAD - Aron Petau
While learning about 3D printing, I was most intrigued by the possibility of modifying and repairing existing products. While there’s an amazing community with many good and free models available, I naturally reached a point where I couldn’t find what I was looking for already designed. I realized that this is an essential skill for effectively operating not just 3D printers, but really any kind of productive machine.
Since YouTube was where I learned everything about 3D printing, and all the people I looked up to there were using Fusion 360 as their CAD program, that’s what I got into. In hindsight, it was a pretty good choice — I fell in love with the possibilities that parametric design gives me. Below you’ll find some of my designs. The process is something I deeply enjoy and want to explore even more.
Through trial and error, I’ve already learned a lot about designing specifically for 3D printing. But I often feel that I lack a deeper understanding of aesthetic considerations in design. I want to broaden my general ability to design physical objects, something I hope to gain during my master’s.
Check out more of my finished designs in the Prusaprinters (now Printables) Community
Besides coming up with new objects, incorporating the real world is also an interest of mine.
Interaction with real objects and environments
In the last few years, I played around with a few smartphone cameras and was always quite sad that my scans were never accurate enough to do cool stuff with them. I couldn’t really afford a proper 3D scanner and had already started cobbling together a Raspberry Pi camera with a cheap TOF sensor. That setup is simple, but not nearly as precise as a laser or LiDAR sensor. Then Apple released the first phones with accessible LiDAR sensors.
Recently, through work at the university, I got access to a device with a LiDAR sensor and started having fun with it. See some examples here:
This last one was scanned with just my smartphone camera. You can see that the quality is notably worse, but considering it was created with just a single, run-of-the-mill smartphone sensor, I think it’s still pretty impressive — and will certainly help democratize such technologies and capabilities.
Perspective
What this section is supposed to deliver is the message that I am currently not where I want to be when navigating the vast possibilities of CAD. I feel confident enough to approach small repairs around the flat with a new perspective, but I still lack technical expertise when it comes to designing collections of composite parts that have to function together. I still have lots of projects half-done or half-thought — and one major reason is the lack of critical exchange within my field of study.
I want more than designing figurines or wearables. I want to incorporate 3D printing as a method to extend the abilities of other tools — to serve mechanical or electrical purposes, be food-safe and engaging. I fell in love with the idea of designing a toy system. Inspired by Makeways on Kickstarter, I’ve already started adding my own parts to their set.
I dream of my very own 3D printed coffee cup — one that is both food-safe and dishwasher-safe. For that, I’d have to do quite a bit of material research, but that only makes the idea more appealing. I’d love to find a material composition incorporating waste, to stop relying on plastics — or at least on fossil-based ones. Once in Berlin, I want to connect with the people at Kaffeform, who produce largely compostable coffee cups incorporating a significant amount of used espresso grounds (albeit using injection molding).
The industry selling composite filaments is much more conservative with the percentage of non-plastic additives, because a nozzle extrusion process is much more error-prone. Still, I would love to explore that avenue further and think there’s a lot to be gained from looking at pellet printers.
I also credit huge parts of my exploration into local recycling to the awesome people at Precious Plastic, whose open source designs helped me out a lot. I find it hard to write anything about CAD without connecting it directly to a manufacturing process. And I believe that’s a good thing. Always tying a design process to its realization grounds the process and gives it a certain immediacy.
To become more confident in this process, I still need more expertise in designing organic shapes. That’s why I’d love to dive deeper into Blender — an awesome tool that in my mind is far too powerful to learn solely through YouTube lessons.

-Chatbot - Aron Petau
The central goal of the entire project was to make the Assistant be entirely speech controlled, such that the phone needn't be touched while immersing yourself in meditation.
The Chatbot was built in Google Dialogflow, a natural language understanding engine that can interpret free text input and identify entities and intents within it, We wrote a custom python backend to then use these evaluated intents and compute individualized responses.
The resulting application runs in Google Assistant and can adaptively deliver meditations, visualize sentiment history and comprehensively inform about meditation practices. Sadly, we used beta functionality from the older "Google Assistant" Framework, which got rebranded months after by Google into "Actions on Google" and changed core functionality requiring extensive migration that neither Chris, my partner in this project, nor I found time to do.
Nevertheless, the whole Chatbot functioned as a meditation player and was able to graph and store recorded sentiments over time for each user.
Attached below you can also find our final report with details on the programming and thought process.
After this being my first dip into using the Google Framework for the creation of a speech assistant and encountering many problems along the way that partly found their way also into the final report, now I managed to utilize these explorations and am currently working to create Ällei, another chatbot with a different focus, which is not realized within Actions on google, but will rather be getting its own react app on a website.

-Coding Examples - Aron Petau
Although pure coding and debugging are often not a passion of mine, I recognize the importance of neural networks and other recent developments in Computer Vision. From several projects regarding AI and Machine Learning that I co-authored during my Bachelor Program, I picked this one since I think it is well documented and explains on a step-by-step basis what we do there.
Image Super-Resolution using Convolutional Neural Networks (Recreation of a 2016 Paper)
Image Super-Resolution is a hugely important topic in Computer Vision. If it works sufficiently advanced, we could take all our screenshots and selfies and cat pictures from the 2006 facebook-era and even from before and scale them up to suit modern 4K needs.
Just to give an example of what is possible in 2020, just 4 years after the paper here, have a look at this video from 1902:
The 2016 paper we had a look at is much more modest: it tries to upscale only a single Image, but historically, it was one of the first to achieve computing times sufficiently small to make such realtime-video-upscaling as visible in the Video (from 2020) or of the likes that Nvidia uses nowadays to upscale Videogames.
Example of a Super-Resolution Image. The Neural network is artificially adding Pixels so that we can finally put our measly selfie on a billboard poster and not be appalled by our deformed-and-pixelated-through-technology face.
A low-resolution sample
A high-resolution sample. This is also called 'ground truth'
The artificially enlarged image patch resulting from the algorithm
A graph showing an exemplary loss function applied during training
One qualitative measurement we used was pixel-wise cosine similarity. It is used to measure how similar the output and the ground truth images are
MTCNN (Application and Comparison of a 2016 Paper)
Here, you can also have a look at another, much smaller project, where we rebuilt a rather classical Machine learning approach for face detection. Here, we use preexisting libraries to demonstrate the difference in efficacy of approaches, showing that Multi-task Cascaded Convolutional Networks (MTCNN) was one of the best-performing approaches in 2016. Since I invested much more love and work into the above project, I would prefer for you to check that one out, in case two projects are too much.
Cars bad. Cars occupy public spaces resulting un a factual privatization of public goods/infrastructure. What if cars could be part of public infrastructure? What can cars provide to the public? With Solar and Electrical Vehicles emerging on the horizon (no endorsement here) it makes sense to think about cars as decentralized powerhouses and public energy storage solutions. Cars, even traditional ones, come equipped with batteries and generate electricity either by driving or though added solar panels. What if this energy could be used to power the public? What if cars would could be used as public spaces? By installing a public USB socket and a public wifi hotspot, on my car, I want to start exploring the potential of cars as public spaces and energy storage solutions.
Within this artistic experiment, I will continuously track the geolocation and energy input/output of my solar equipped car and make the data publicly available. I will also track the amount of energy that is not used by the car and could be used by the public. Taking steps towards optimal usage of existing electrical and other infrastructure is only possible by breaking conventional notions of public ownership and private property. This project is one step towards a more sustainable and equitable future.
Introduction
We all know by now that cars and individual traffic presents a major environmetal and societal problem all over the world. The last 70 something years of building car infrastructure are culminating in many areas in a dead end where the only thinkable solution is to build more roads and cars. THis is obviously a larger problem than one project can tackle, but here is one outlook on how
Experiment
Preexisting data
With the data collected over the last year of using the car privately I can show with embarrasing accuracy how underutilized the system is and calculate an estimate of energy lost due to societal notions of private property. The data will be an estimate, since the monitoring itself is dependent on solar energy and the internet connection is spotty at best when it is not supplied with electricity.
Monitoring
In the Car, there is a Raspberry Pi 4 Microcomputer running a custom Operating Systen that monitors the following data:
Solar Intake (W)
Battery Level (V)
GPS Location
Total Energy Produced (Wh)
Total Energy Consumed (Wh)
Solar Energy Potential (Wh)
Through the router I can also track total Wifi usage and the number of connected devices.
Public Wifi
For the Project, I opened a router in the Car towards the Public, much alike to ahotspot you would find in a cafe. I use my own data plan on there, which I never max out anyways. The router is a Netgear M1 and has a 4G Modem built in. It is connected to the Raspberry Pi and is powered by the secondary car battery.
Public Energy: A USB Socket
I plan on installing a USB Socket on the outside of the car, so people can charge their devices. The socket will be connected to the secondary car battery and will be powered by the solar panels. The socket will be installed in a way that it is not possible to drain the battery completely.
Communication
Nobody expects any help or public supplies from car owners. How to communicate the possibility to the outside world? The plan is to fabricate a vinyl sticker that will be applied to the car. The sticker will contain a QR Code that will lead to a website with the data and a short explanation of the project. Visual cues lead to the USB Socket and the Wifi Hotspot.
Issues
Space / Scale
Obviously, the space on top of a car is quite limited and from a sustainability perspective, it would be better to have a larger solar array on a roof of a house. The point is not to advocate for a mandated solar install on cars, but to optimize and share preexisting infrastructure. The car is already there, it already has a battery and it already has solar panels. Looking at many Camper-Van builds, the amount of cars with already installed solar panels is quite large. The point is to make the most out of it.
Legality
Germany has laws in place holding the owner of a Internet Connection liable for the legality of the traffic that is going through it. This is a major issue for the project, as I do not want to be liable for the traffic that is going through my car. I am currently looking into ways to circumvent this issue.
Surveillance / Privacy
The Car is equipped with a GPS Tracker and a Wifi Hotspot. This means that I can track the location of the car and the number of devices connected to the hotspot. I am not tracking any data that is going through the hotspot, but I could. As this project will generate public data, People using and maybe depending on the internet and electricity provided will be tracked by proxy. I am not sure how to deal with this issue yet. One potential solution would be to publish the data only in an aggregated form, but this would make the data less useful for other projects.
Security / Safety
My Car is now publicly traceable. I am no Elon Musk, and the idea does not really concern me, but we did create an additional attack vector for theft here.
It holds Geocodes, has hourly data and could tell the difference between geocoded potential solar energy and actual energy. It also has temperature records.
There are 2 types of Losses in the system:
Either the Batteries are full and available energy cannot be stored
Or the solar panels are blocked through urban structures and sub-optimal parking locations.
Interesting Questions:
How far away from optimal usage are my panels and where does the difference stem from?
Where to go?
I think, the difference between potential energy and actual electricity produced/consumed is interesting. How large is the gap? Is it relevant —> my initial guess would be that it is enormous How to close the gap?
—> install outside usb plugs It would be publicly available infrastructure, people could charge their smartphones anywhere —> QI charging for security concerns??
Scaling?? —> mandate solar roofs for cars? How effective would it actually be? What about buses / public vehicles?
+++
Potential issues with the data:
Spotty / intermittent internet connection
Noisy?
Making Cars public spaces
What could my car provide to the public to be less wasteful with its space?
Provide Internet
Would incur monthly costs
Provide Electricity
Concrete Problems
How to make sure people cannot fully drain my battery? How dangerous is actually an exposed USB Socket? Can people short my electronics through it?
How scalable are solutions like these?
Are public USBC Sockets something that would actually be used? Could there be a way for people to leave their stuff charging? What if I actually move the car and someone has their equipment still attached? Would people even leave their stuff unattended?
Can cars provide positive effects to public spaces? —> how to pose this research question without redeeming the presence of cars in our public spaces?
Difference Electric - Fuel cars
there is lots of research on using Electric cars as transitional energy storage. Even before "flatten the curve" became a common slogan, electrical engineers worried about the small energy spikes in the grid. The existence of these forces us to keep large power plants running at all times, even if the energy is not needed. The idea is to use the batteries of electric cars to store this energy and use it when needed.
Forum entries from the Seminar: Critical Epistemologies
On Anderson: Institutions
Note
Source Text: Epistemic Justice as a Virtue of Social Institutions Elizabeth Anderson (2012) Epistemic Justice as a Virtue of Social Institutions, Social Epistemology, 26:2, 163-173, DOI: 10.1080/02691728.2011.652211 Publication
The text by Anderson helped shed light on a few issues I stumbled over with Frickers Account. On top of the various issues I and seemingly others have with her virtue-based approach, I think a utilitarian angle is worth considering. That would be: okay, I accept that people can help fight injustice by realising their privilege, showing restraint, silencing themselves, and adopting the benevolent listening approach. I think that is a practical, virtuous, and realistic endeavour. But is it the effective path to alleviating structural injustice? I think not, and initially, that is a major reason I discarded Fricker’s approach, although I saw merit. I have similar concerns to Anderson in the scalability of virtues. Virtuous behavior might help my personal well-being, it gives me normative elevation and might even further the quality of relationships I have. But is it applicable to society, is it enough to counteract structural injustice? Well, maybe, assuming that:
Everyone realizes their privilege,
Everyone concludes that justice is the right goal,
Upon deciding to adopt a virtuous stance, everyone at least moderately succeeds in practicing what they preach.
I think, for society, the same society that came up with patriarchy in the first place, external pressure, some measure independent of the convictedness of the subjects is needed. Anderson made the powerful point of: “Anything that works, goes”, which took me some time to appreciate. I am always angry when I get told to keep my shower to a minimum or stop using plastic straws when I know exactly that my using less water is nothing compared to the institutionalized practice of Coca-Cola putting water into bottles. I feel like it is unjustified to ask me to save water while others triple their output, for performance. The same thing applies to Epistemic injustices. It strikes me how much energy it costs to keep up virtuous behavior individually and how little effect there is to show for it. I do not believe in “trickling up” where institutions will eventually adopt individual practices. Is Fricker thereby less right in her point? No, it adds up, as an entire population showering shorter adds up to lots of water saved. Anderson also points out how locally innocent biases can create injustice on a “macro” scale. Another indicator for me is that local virtue is not the sole solution, as it can still feed and sustain a system enforcing epistemic injustice.
I still have doubts about what to do now with my ideas, on how the world looks that I want. I lack the imagination of seeing a world that is epistemically just, and it is hard to strive for something one cannot even imagine. The system is inherently leaning toward inequality, if I try to balance something on a needle, it will only go well so long, before small imbalances create chain reactions and the object should be called unstable. Should we even succeed in “resetting” society, creating equal participation for each subject, how will it remain just? Is Justice always a conjunct of Equality? Are there ways to achieve real Justice without needing equality?

On Medina, the informant and the inquirer
Note
Source Text: Dr. José Medina (2012) Hermeneutical Injustice and Polyphonic Contextualism: Social Silences and Shared Hermeneutical Responsibilities, Social Epistemology, 26:2, 201-220, DOI: 10.1080/02691728.2011.652214 Publication
My biggest takeaway here was that, as I tried to hint at in an earlier comment, Whenever we talk about justice, this necessarily refers to a relational concept, where everybody has a double role to ensure successful communication. Medina calls these the inquirer and the informant. So, every individual has to make sure to act to her capacity as an epistemologically sound knowledge-acquiring agent (the inquirer). This would involve knowing when and how to falsify/qualify statements, making inferences about the theory of mind, and generally comparing different statements. The other role is the informant, where the individual should have the capacity to function as an object in an inquiry by another. Very roughly this can, I think, be compared to any good communication model, where there are a listener and a speaker, and both have to function. What was new here, or at least came out more clear is that it not only depends on the capacity of both of these roles on the subject, but it is also directly dependent on the “other”, the agent opposite of the subject. We may call this other society later but it helps me to visualize the other as an individual nonetheless. Where the analogy to communication now fails, in my opinion, is this cross-dependence, where an agent does not fully determine her capacity to act both as an inquirer and as an informant, it is co-determined by the “other”. So, if I, as an “other”, listen to someone's statements, and I fail or refuse to understand the epistemic content of the message, I am not only impairing my epistemic agency, but I also hurt the epistemic agency of the subject. Maybe obvious to most, but this thought struck me as being exactly the point of leverage for dysfunctionalities in power relations. Also argued convincingly in the paper was that these are distinct and independent agencies, which can be impairing an individual separately. Overall, the Medina text was incredibly helpful after the somewhat confusing Fricker text that felt incomplete and left a lot of questions for me. The medina text picked up all my initial doubts, that I couldn't properly formulate, and many more, while still holding to the general framework of Fricker. Although I was not convinced by the Fricker Text, I tend to think the strategy:
"When in doubt, give the subject full epistemic credibility"
Is a good strategy that might alleviate a lot of issues regarding functions of power, and hierarchy, but also further, it might be a good counter for things as our confirmation bias, expectation bias and many individual errors that we could minimize by constantly exposing ourselves to falsifiability through others (voluntarily). Sounds like science applied to agency to me.

On Jaggar: Norms, Outlaw Emotions, and the Ideal Society
Note
Source Text: Alison M. Jaggar (1989) Love and knowledge: Emotion in feminist epistemology, Inquiry, 32:2, 151-176, DOI: 10.1080/00201748908602185 Publication
I found Jaggar to be a very wholesome read, it was the perfect amount of grounded argumentative structure and felt very connected as a whole. This was, together with the ideas from Lugones the best and most fruitful paper for me. On outlaw emotions: First, I hate the term, I think it’s placative and fails to frame the (actually nice) idea behind it. Outlaw Emotions are all those emotions incompatible with the dominant norms. That’s a huge field to cover, among feminist emotions they would also encompass emotions that are irrational or “faulty”. So, Jaggar does the term Justice by saying, some, but not all Outlaw Emotions are Feminist emotions. To make this evident, just think of a murderer's joy for killing, it is of no feminist interest to dissect, yet it is against dominant values. So, experiencing Outlaw emotions is a (probably) necessary, but not sufficient condition for feminism. The incompatible emotion serves to create discourse and change. Jaggar convincingly shows how emotions have a direct influence on beliefs and can validly constitute evidence, while simultaneously validly influencing values in a similar manner. When we talk about dominant/alternative norms, we already endorse hierarchy in society. We acknowledge its existence, simply by identifying the dominant norm. I am not quite sure what exactly Jaggar proposes we should do with the hierarchy structures in society. Explicitly I can read: Subcultures rejecting dominant norms should be formed, to create counterbalances and a somewhat fair discourse over the topic. “How can we determine which outlaw emotions are to be endorsed or encouraged and which rejected? In what sense can we say that some emotional responses are more appropriate than others? What reason is there for supposing that certain alternative perceptions of the world, perceptions informed by outlaw emotions, are to be preferred to perceptions informed by conventional emotions? Here I can indicate only the general direction of an answer, whose full elaboration must await another occasion. I suggest that emotions are appropriate if they are characteristic of a society in which all Human Life (and perhaps some nonhuman life, too) thrive, or if they are conducive to establishing such a society.” To me this passage sounds sketchy at best, there is no indication of how to successfully separate appropriate from inappropriate emotions. Roughly, I read this part as: emotions are warranted iff they increase the balance of power. (equivalent to minimizing the height of the hierarchy) I would love to get to read this “other occasion” because it seems indefensible to me to formulate a norm that states: Accept only emotions which eliminate/diminish norms. The idea roughly resembles Rawls's Minimax Principle, where a policy should be implemented iff the benefit for the most disadvantaged is highest. Another thing I found helpful is her reformulation of what norms do: “Dominant Norms tend to serve dominant interests” til here nothing new, this is a tautology for me, I understand norms as identical to dominant interests, that’s literally what norms are. Is an alternative, suppressed norm even thinkable? Isn't it inherent in a norm that it be the dominant one? But then, after that: "Whatever our color / gender / class / sexual orientation, we are likely to adopt the dominant value of racist, classist, homophobe, misogynistic white men." This was rather helpful to me, as it reframes the “act” of oppression as the “likelihood of value distribution” being skewed in your favor, making everybody’s values more likely to be similar to yours. This nicely illustrates how a system can be hierarchical and oppressive, without anybody actively, intentionally “acting oppressive”, while still perpetuating oppression. I'm not saying everybody is acting unintentionally oppressive, but it is always hard to imagine for me to picture "White Men" forming a group and collectively deciding on who to hate this coming season, Conceptually separating "being oppressed" and "oppressing" into phenomena without necessary inherent causal relation makes sense to me here.

-Critical Philosophy of Subjectivity - Aron Petau
Citation from Butler, Page 51, citing Ewald, which is, in turn, interpreting Foucault:
The norm integrates anything which might attempt to go beyond it—nothing, nobody, whatever difference it might display, can ever claim to be exterior, or claim to possess an otherness which would actually make it other” (Norms, Discipline, and the Law, P.173)
Such a view suggests that any opposition to the norm is already contained within the norm, and is crucial to its functioning.
Here, for me, the entire futility of the approach later identified and described is condensed into a few sentences.
Hence, regulations that seek merely to curb certain specified activities (sexual harassment, welfare fraud, sexual speech) perform another activity that, for the most part, remains unmarked: the production of the parameters of personhood, that is, making persons according to abstract norms that at once condition and exceed the lives they make—and break. Page 56, final sentence
The idea that it is impossible to legislatively regulate norms without propelling, propagating, and carving them out deeper resonates with me, but at the same time, it has left me undecided on how to proceed. I understand the first citation to clearly be Ewald's interpretation of things and am not sure whether Foucault's careful circumvention of the term "Norms" is related to anticipation of this argument.
Further, I am not sure I share Ewald's interpretation; I see that the object "othered" by a norm is a constituent and necessary object for the norm, simply due to its "comparative" nature (p. 51, citation from Ewald). The oppressed may well be as constituting of norms as the privileged, but this does not translate to a normative responsibility nor a pang of guilt in my opinion. The dangerous argument that the oppressed bear responsibility for their situation is too close for my taste. I would like to emphasize a clear cut between constituting and reinforcing a norm and thriving on it. Yes, maybe that is a good location to make the cut: The normative and ethical pressure, or better, the guilt of complicity lies with the ones thriving BECAUSE of a norm and clearly not with those thriving DESPITE OF a norm. I would think that Butler makes a similar argument elsewhere, but as such, I was missing it here, resulting in a very bleak and hopeless situation where any struggle to change the status quo through legislation is doomed and inevitably propagates and reinvents stable unfair relations of power.

Some tiny details about norms that stuck out to me about the norm were that: 1: they are fictional and thus, an object conforming to a norm is not more meaningful than an object not conforming to a norm. 2: the entire given set comprises the norm, the deviations play a defining role in the formation of the norm itself (or an average). p. 152: Under norm, 3 phenomena are subsumed: Discipline, less as a constraint, but more as a regulatory mechanism insurance, Reducing objects to their relative occurrence, distributing risk. and standardization. The norm has three defining features:
positivism, as reliant on facts, which have an aura of objectivity around them.
relativity, they are neither absolute nor universal, they have a scope, both in definition as a certain temporal extension.
polarity involving a classification between the normal and the abnormal, where the abnormal is to be some handicap, not attaining something that the normal does attain.
What, then, is a norm?
It is a way for a group to provide itself with a common denominator in accordance with a rigorous principle of self-referentiality, with no recourse to any kind of external reference point, either in the form of an idea or an object. The normative process can obey a variety of different logics: the panoptical logic of discipline, the probabilistic schema of insurance, or the communicative logic of the technical norm. These three logics have the same form: in each case, the rule which serves as a norm, by virtue of which everyone can measure, evaluate, and identify himself or herself, will be derived from those for whom it will serve as a standard. A strange logic, this, which forces the group to turn back in upon itself and which, from the moment it establishes itself, will let no one escape its purview. p. 154

On Foucault: The effects without effector
Note
Source Text: Michael Foucault. Power/knowledge: Selected interviews and other writings 1972–1977. Pantheon, New York, 1980. Publication
one finds all sorts of support mechanisms [...] which invent, modify and re-adjust, according to the circumstances of the moment and the place- so that you get a coherent, rational strategy, but one for which it is no longer possible to identify a person who conceived it. p. 203
In this passage, and the one following it, I think Foucault pinpoints as one of the central attributes of the apparatus (or dispositif) the arbitrariness of the order of power relations. There is no identity having to undergo some sort of inventive process to start off a collective change, a "strategy" just happens to meet the criteria for deployment.
But between the strategy which fixes, reproduces, multiplies and accentuates existing relations of forces, and the class which thereby finds itself in a ruling position, there is a reciprocal relation of production. Thus one can say that the strategy of moralising the working class is that of the bourgeoisie. One can even say that it's the strategy which allows the bourgeois class to be the bourgeois class and to exercise its domination. But what I don't think one can say is that it's the bourgeois class on the level of its ideology or its economic project which, as a sort of at once real and fictive subject, invented and forcibly imposed this strategy on the working class.
This was for me the most powerful grasp of what an apparatus is. A complicated removal of the effector from the effect. I struggle to continue to find any substance to the relations of the classes. Does reciprocal mean anything more than both are constitutive of each other? One produces the means of reproduction of the other, but where exactly can I apply moral judgements? This whole ordeal and now I lack subjects to blame. How can this theory possibly bring about change in society? Is that even its goal? Do we undergo this analysis in order to make society better in the end?

-Dreams of Cars - Aron Petau
In the context of the course "Fotografie Elementar" with Sebastian Herold I developed a small concept of urban intervention. The results were exhibited at the UdK Rundgang 2023 and are also visible here.
Dreams of Cars
These are not just cars. They are Sport Utility Vehicles. What might they have had as hopes and dreams on the production line? Do they dream of drifting in dusty deserts? Climbing steep rocky canyon roads? Sliding down sun-drenched dunes? Discovering remote pathways in natural grasslands? Nevertheless, they did end up in the parking spots here in Berlin.
What drove them here?

Echoing Dimensions
By Aron Petau and Joel Tenenberg • 4 minutes read •
The exhibition is situated in an old parking garage, owned and operated by the studierendenwerk Berlin. The space is a large, open room with a rather low ceiling and a concrete floor. Several Nooks and separees can create intimate experiences within the space. The space is not heated and has no windows. The walls are made of concrete and the ceiling is made of concrete.
As a group, we are 12 people, each with amazing projects surrounding audiovisual installations:

The Collective Exibition Text:
Sound, as a fundamental element of everyday experience, envelopes us in the cacophony of city life - car horns, the chatter of pedestrians, the chirping of birds, the rustle of leaves in the wind, notifications, alarms and the constant hum of radio waves, signals and frequencies. These sounds, together make up the noise of our life, often pass by, fleeting and unnoticed. The engagement with sound through active listening holds the potential to process the experience of the self and its surroundings. This is the idea of “Echoing Dimensions”: Once you engage with something, it gives back to you: Whether it is the rhythmic cadence of a heartbeat, a flowing symphony of urban activity or the hoofbeats of a running horse, minds and bodies construct and rebuild scenes and narratives while sensing and processing the sounds that surround them, that pass next and through them. The exhibition "Echoing Dimensions" takes place at Kunstraum Potsdamer Straße gallery’s underground space and exhibits artworks by 12 Berlin based artists, who investigate in their artistic practice ‘intentional listening’ using sound, video and installation, and invites to navigate attentiveness by participatory exploration. Each artwork in the exhibition revolves around different themes in which historical ideas resonate, political-personal narratives are being re-conceptualized and cultural perspectives are examined. The exhibition's common thread lies in its interest into the complexities of auditory perception, inviting viewers to consider the ways in which sound shapes our memories, influences our culture, and challenges our understanding of space and power dynamics.

Working TD Prototype. We collect the pointcloud information through a kinect azure and sorting the output of the device turned out to be quite tricky.
2024-03-01
Initial live testing on the finalized hardware. We decided to use a tiny Intel NUC to run both touchdesigner, the LLM, and audio synthesis.
Not expected at all: The audio synthesis was actually the hardest, since there was no available internet in the exhibition space and all sleek modern solutions seem to rely on cloud services to generate audio from text. Here, the tiny NUC really bit us: it took almost 15 seconds to generate a single paragraph of spoken words, even when usin quite small synthesizer models for it.
Lesson learned: Next time give it more oomph. I seriously wonder though why there wouldn't be better TTS systems around. Isnt that quite the essential accessibility feature? We ended up using coquiTTS, which is appearently out of business entirely.
This is a collection of Gallery Spaces and Collectives that provide a fresher and more counter-cultural perspective on the Gallery Weekend. It quite helped our online visibility and filled out the entire space on the Opening.

einszwovier: löten und leuchten
By Aron Petau and Friedrich Weber Goizel • 4 minutes read •
A hands-on course in soldering, electronics, and lamp design for young creators
Löten und Leuchten has now run in three successful iterations — each time offering 5th and 6th graders a guided yet exploratory dive into the worlds of electronics, making, and digital design. At its core, the course is about understanding through creating: introducing young learners to tangible technologies and encouraging them to shape the outcome with their own ideas and hands.
The Project
Over three sessions (each lasting three hours), participants designed and built their own USB-powered LED lamp. Along the way, they soldered electronic components, modeled lamp housings in 3D, learned about light diffusion, and got a direct introduction to real-world problem solving. Every lamp was built from scratch, powered via USB — no batteries, no glue kits, just wire, plastic, and a bit of courage.
The children began by learning the basics of electricity through interactive experiments using the excellent Makey Makey boards. These allowed us to demonstrate concepts like conductivity, input/output, and circuitry in a playful and intuitive way. The enthusiasm was immediate and contagious.
From there, we moved to the heart of the project: cutting open USB cables, preparing and soldering 5V LEDs, and designing enclosures for them. The soldering was always supervised, but each child did their own work — and it showed. There's something deeply satisfying about holding a working circuit you assembled yourself, and many kids expressed how proud they were to see their light turn on.
Designing with Tools — and Constraints
For 3D modeling, we used Tinkercad on iPads. While the interface proved very accessible, we also encountered its limits: the app occasionally crashed or froze under load, and file syncing sometimes led to confusion. Nonetheless, it provided a gentle, well-mediated entry point to CAD. Most kids had never touched 3D design software before, but quickly began exploring shapes, tolerances, and fitting dimensions. The lamps they created weren’t just decorative — they had to functionally hold the electronics, which added a very real-world layer of complexity.
The printed shades were all done in white PLA to support light diffusion. This led to organic conversations around material properties, translucency, and light behavior, which the kids quickly absorbed and applied in their designs.
Real Challenges, Real Thinking
The project hit a sweet spot: it was challenging enough to be meaningful, but achievable enough to allow for success. Every child managed to finish a working lamp — and each one was different. Along the way, they encountered plenty of design hurdles: USB cables that needed reinforcement, cases that didn’t fit on the first try, LEDs that had to be repositioned for optimal glow.
We didn’t avoid these issues — we embraced them. Instead of simplifying the process to a formula, we treated every obstacle as an opportunity for discussion. Why didn’t this fit? What could we change? How do you fix it? These moments turned into some of the richest learning experiences in the course.
Bonus Round: Tabletop Foosball
As a closing challenge, each group designed their own mini foosball table, using whatever materials and approaches they liked. This final task was light-hearted, but not without its own design challenges — and it served as a great entry into collaborative thinking and prototyping. It also reinforced our goal of learning through play, iteration, and autonomy.
Reflections
Across all three runs, the workshop was met with enthusiasm, curiosity, and real focus. The kids were engaged from start to finish, not just with the tools, but with the ideas behind them. They walked away with more than just a glowing lamp — they gained an understanding of how things work, and a confidence that they can build things themselves.
For us as facilitators, the course reaffirmed how powerful hands-on, self-directed learning can be. The combination of digital and physical tools, real constraints, and open-ended outcomes created an environment where creativity thrived.
Löten und Leuchten will continue to evolve, but its core will remain: empowering kids to build things they care about, and helping them realize that technology isn’t magic — it’s something they can shape.

einszwovier: making of
By Aron Petau and Friedrich Weber Goizel • 2 minutes read •
We started constructing and planning the layout and equipment for the room. We had the chance to build the wooden workbench ourselves, making it our own.
December 2024 – A Space for Ideas Becomes Reality
After months of planning, organizing, and anticipation, it finally happened in December 2024: our Maker Space “studio einszwovier” officially opened its doors. In the midst of everyday school life, an innovative learning environment came to life—one that combines creativity, technology, and educational equity.
From Concept to Reality
The idea was clear: a space where “making” becomes tangible—through self-directed and playful work with analog and digital tools. Learners should be able to shape their learning process, discover their individual strengths, and experience the empowering motivation of doing things themselves.
To support that, the room was equipped with state-of-the-art tools: 3D printers, laser cutters, microcontrollers, and equipment for woodworking and textile printing enable hands-on, project-based learning.
A Place for Free and Explorative Learning
Led by Aron and Friedrich — both graduate students in Design + Computation in Berlin—the “studio einszwovier” provides access to tools, materials, and knowledge. It’s a place for open-ended, explorative learning that emphasizes not just digital technologies, but also creativity, problem-solving, and initiative. The students are invited to join both courses with a predefined focus and open "tüftling".
Open Doors for Creative Minds
“studio einszwovier” is open Tuesdays to Thursdays from 11:00 AM to :00 PM. A dedicated open lab time is available Wednesdays from 1:30 PM to 3:00 PM. Everyone is welcome to drop in, share ideas, and get started.
A Space for the Future
With studio einszwovier, we’ve created a space where learning through hands-on experience takes center stage—promoting both practical and digital skills for the future. It’s a place where ideas become tangible outcomes and where the learning culture of our school grows in a lasting and meaningful way.

einszwovier: vogelvilla
By Aron Petau and Friedrich Weber Goizel • 2 minutes read •
After our first course, löten und leuchten, the next idea was to create a format for the laser cutter. We were targeting older kids this time, from the year 9 on up. We looked up on 3Axis.co for inspiration and it seemed important to both of us that we would be able to create something large and useful. So a groupwork project seemed ideal and we settled on birdhouses pretty quickly.
At the space, we have a pretty large and powerful Xtool S1, which is capable of cutting up to 10mm plywood.
But a birdhouse, with all its sides, ends up using quite a bit of material, sowe spent quite a bit of prep time optimizing the base design so one hous can be made using only 3 A3 sheets of plywood.
We invented a joint memory game, to incentivize thinking about all the larger possibilities of the laser cutter. During their own process, the kids found out for themselves the pros and cons of modular or reversible design and were designing their own birdhouses entirely in Tinkercad and Xtool Creative Space. We also had a lot of fun with the laser cutter, and the kids were able to create their own designs and engravings.
We laid out the course for 3 days again, but slightly underestimated the time necessary for larger cuts end engravings. We were unable to finish the birdhouses in time on day 3, with each only needing less than an hour or so for waterproofing and finishing touches. Next time, we would make this a 4 day course :) Despite not completely finishing, the feedback was good again and apparently provided a solid entryway into 2D Sheet manufacturing and Lasercutting. A big shoutout also goes out to our new favourite site, Boxes.py for providing a ton of amazing parametric files that gave great easy inspiration especially in jointing options for the kids.
To be continued...

-Homebrew - Aron Petau
I love hosting, I love experimenting in the Kitchen. Starting with homebrews was a natural fit for me and during the first wave of Covid-19, I went the whole homebrewer’s route of bottle fermentation and small batches later elevating my game with larger batches of 50 liters and a pressure tank system.
Starting out, I found it fascinating, how just 4 rather simple ingredients, malt, hops, water and yeast, can form such an incredible range of taste experiences. It was and still is, a tremendous learning experience, where one slowly has to accept not being able to control the process fully and find room for creativity.
Why do I present such an unrelated non-academic hobby here? I simply do not regard it as unrelated, experimenting and optimizing a process and a workflow, creating optimal conditions for the yeast to do its job feels very similar to approaching a coding project. Yeast and what it does fascinates me. Every time I open the latch to release some pressure on the Tank I think of the awesome symbiotic relationships yeast has with humans and how many different strains live there together to create a unique, yet tailored flavor. Several ideas are floating around of changing the brewing process by capturing the created carbon dioxide and using it productively. I could see a car tire being filled with my beer gas, or an algae farm munching away on my CO2 byproducts. Within a closed-loop pressurized system, such ideas actually become realizable and I would love to explore them further.
I am not yet an expert on algae, but I can manage with yeast and I believe they can coexist and create a more sustainable cycle of production. Young Henrys, a brewery in Australia is already incorporating algae into its industrial process: The Algae project
Such ideas do not come into the industry by themselves: I believe that art and the exploratory discovery of novel techniques are the same things. Good and inventive design can improve society and make steps towards sustainability. I want to be part of that and would love to find new ways of using yeast in other design contexts: See whether I can make them work in a closed circular system, make them calculate things for me, or simply making my next beer taste awesome with just the right amount of fizz.

Impressions from the International Smelting Days 2021
The concept
Since I was a small child I regularly took part in the yearly international congress called Iron Smelting Days (ISD). This is a congress of transdisciplinary people from all over Europe, including historians, archeologists, blacksmiths, steel producers, and many invested hobbyists. The proclaimed goal of these events is to understand the ancient production of iron as it happened throughout the iron age and also much after. A bloomery furnace was used to create iron. Making iron requires iron ore and heat under the exclusion of oxygen. It is a highly fragile process that takes an incredible amount of work. The designs and methods vary a lot and were very adapted to the region and local conditions, unlike the much later, more industrialized process using blast furnaces.
To this day it is quite unclear how prehistoric people managed to get the amount and quality of iron we know they had. The furnaces that were built were often clay structures and are not preserved. Archeologists often find the leftover burned ore and minerals, giving us some indication of the structure and composition of the ancient furnaces. The group around the ISD takes up a practical archeological approach and we try to recreate the ancient methods with the added capability of maybe sticking temperature probes or electric blowers. Each year we meet up in a different European city and try to adapt to the local conditions, often with local ore and local coal. It is a place where different areas of expertise come together to educate each other while sitting together through the intense day- and night shifts to feed the furnaces. Since being a kid, I started building my own furnaces and read up on the process so I could participate. Technology gets a different tint when one is involved in such a process: Even the lights we put up to work through the evening are technically cheating. We use thermometers, meticulously weigh and track the inbound coal and ore, and have many modern amenities around. Yet - with our much more advanced technology, our results are often inferior in quantity and quality in comparison with historical findings. Without modern scales, iron-age people were more accurate and consistent than we are.
After some uncertainty about whether it would take place in 2021 again after it was canceled in 2020, a small group met up in Ulft, Netherlands. This year in Ulft, another group made local coal, so that the entire process was even lengthier, and visitors came from all over to learn about making iron the pre-historic way.
Below I captured most of the process in some time-lapses.
The Process
Here you can see a timelapse of me building a version of an Iron Furnace
As you can see, we are using some quite modern materials, such as bricks, this is due to the time constraints of the ISD. Making an oven completely from scratch is a much more lengthy process requiring drying periods in between building.
After, the furnace is dried and heated up
Over the course of the process, more than 100 kgs of coal and around 20 kgs of ore are used to create a final piece of iron of 200 - 500g, just enough for a single knife.
With all the modern amenities and conveniences available to us, a single run still takes more than 3 people working over 72 hours, not accounting for the coal-making or mining and relocating the iron ore.

For me, it is very hard to define what technology encompasses. It certainly goes beyond the typically associated imagery of computing and industrial progress. It is a mode of encompassing the world and adopting other technologies, be it by time or by region makes me feel how diffused the phenomenon of technology is into my world.

-Käsewerkstatt - Aron Petau
One day earlier this year I woke up and realized I had a space problem. I was trying to build out a workshop and tackle ever more advanced and dusty plastic and woodworking projects and after another small run in with my girlfriend after I had repeatedly crossed the "No-Sanding-and-Linseed-Oiling-Policy" in our Living Room, it was time to do something about it. I am based in Berlin right now and the housing market is going completely haywire over here ( quick shoutout in solidarity with Deutsche Wohnen und Co enteignen). End of the song: I won't be able to afford to rent a small workshop anywhere near berlin anytime soon. As you will notice in some other projects, I am quite opposed to the Idea that it should be considered normal to park ones car in the middle of the city on public spaces, for example Autoimmunitaet, Commoning Cars or Dreams of Cars.
So, the idea was born, to regain that space as habitable zone, taking back usable space from parked cars. I was gonna install a mobile workshop within a trailer. Ideally, the trailer should be lockable and have enough standing and working space. As it turns out, Food Trailers fulfill these criteria quite nicely. So I got out on a quest, finding the cheapest food trailer available in germany.
6 weeks later, I found it near munich, got it and started immediately renovating it.
Due to developments in parallel, I was already invited to sell food and have the ofgficial premiere at the Bergfest, a Weekend Format in Brandenburg an der Havel, initiated and organized by Zirkus Creativo. Many thanks for the invitation here again!
So on it went, I spent some afternoons renovating and outfitting the trailer, and did my first ever shopping at Metro, a local B2B Foodstuffs Market.
Meanwhile, I got into all the paperwork and did all the necessary instructional courses and certificates. The first food I wanted to sell was Raclette on fresh bread, a swiss dish that is quite popular in germany. For the future, the trailer is supposed to tend more towards vegan dishes, as a first tryout I also sold a bruschetta combo. This turned out great, since the weather was quite hot and the bruschetta was a nice and light snack, while I could use the same type of bread for the raclette.
The event itself was great, and, in part at least, started paying off the trailer.

We encountered lots of positive feedback and I am looking forward to the next event. So, in case you want to have a foodtruck at your event, hit me up!

-Lampshades - Aron Petau
During 2022, I was exposed to some of the awesomenest tools for architects. One of them was Rhino, a 3D modeling software that is used for a lot of architectural design. I hate it. It has quite an unreadable interface and is not very intuitive, with straight-up 80s vibes. It has plugins though, and one of them is Grasshopper, a visual programming language that is used to create parametric models. Grasshopper is insanely powerful and seems to be a full-fledged programming language, but it is also very intuitive and easy to use, rather similar to the new node-based flows unreal engine and blender are now starting. Sadly, grasshopper does not come as a standalone, and it requires Rhino to run and achieve many of the modeling steps.
In that combination, Rhino suddenly becomes much more appealing, and I started to enjoy the process of modeling in it. I was able to create a parametric lampshade that I am very happy with and can modify on the fly for ever-new lampshades.
Then printing it with white filament in vase mode was a breeze and here you can see some of the results.

-Local Diffusion - Aron Petau
Is it possible to create a graphic novel with generative A.I.? What does it mean to use these emerging media in collaboration with others? And why does their local and offline application matter?
With AI becoming more and more democratised and GPT-like Structures increasingly integrated into everyday life, the black-box notion of the mysterious all-powerful Intelligence hinders insightful and effective usage of emerging tools. One particularly hands-on example is AI generated images. Within the proposed Workshop, we will dive into Explainable AI, explore Stable Diffusion, and most importantly, understand the most important parameters within it. We want to steer outcomes in a deliberate manner. Emphasis here is on open and accessible technology, to increase user agency and make techno-social dependencies and power relations visible.
Empower yourself against readymade technology! Do not let others decide on what your best practices are. Get involved in the modification of the algorithm and get surprised by endless creative possibilities. Through creating a short graphic novel with 4-8 panels, participants will be able to utilise multiple flavours of the Stable Diffusion algorithm, and will have a non-mathematical understanding of the parameters and their effects on the output within some common GUIs. They will be able to apply several post-processing techniques to their generated images, such as upscaling, masking, inpainting and pose redrawing. Further, participants will be able to understand the structure of a good text prompt, be able to utilise online reference databases and manipulate parameters and directives of the Image to optimise desired qualities. Participants will also be introduced to ControlNet, enabling them to direct Pose and Image composition in detail.
Workshop Evaluation
Over the course of 3 hours, I gave an introductory workshop in local stable diffusion processing and introduced participants to the server available to UdK Students for fast remote computation that circumvents the unethicality of continuously using a proprietary cloud service for similar outputs. There is not much we can do on the data production side and many ethical dilemmas surrounding digital colonialism remain, but local computation takes one step towards a critical and transparent use of AI tools by Artists.
The Workshop format was rathert open and experimental, which was welcomed by the participants and they tried the collages enthusiastically. We also had a refreshing discussion on different positions regarding the ethicalities and whether a complete block of these tools is called for and feasible.
I am looking forward to round 2 with the next iteration, where we are definitely diving deeper into the depths of comfyui, an interface that i absolutely adore, while its power also terrifies me sometimes.

-Lusatia - an immersion in (De)Fences - Aron Petau
Plastics offer significant material benefits, such as durability and versatility, yet their widespread use has led to severe environmental pollution and waste management challenges. This thesis develops alternative concepts for collaborative participation in recycling processes by examining existing waste management systems. Exploring the historical and material context of plastics, it investigates the role of making and hacking as transformative practices in waste revaluation. Drawing on theories from Discard Studies, Material Ecocriticism, and Valuation Studies, it applies methods to examine human-waste relationships and the shifting perception of objects between value and non-value. Practical investigations, including workshop-based experiments with polymer identification and machine-based interventions, provide hands-on insights into the material properties of discarded plastics. These experiments reveal their epistemic potential, leading to the introduction of novel archiving practices and knowledge structures that form an integrated methodology for artistic research and practice. Inspired by the Materialstudien of the Bauhaus Vorkurs, the workshop not only explores material engagement but also offers new insights for educational science, advocating for peer-learning scenarios. Through these approaches, this research fosters a socially transformative relationship with waste, emphasizing participation, design, and speculative material reuse. Findings are evaluated through participant feedback and workshop outcomes, contributing to a broader discussion on waste as both a challenge and an opportunity for sustainable futures and a material reality of the human experience.

-Philosophy - Aron Petau
I have attended a fair share of philosophical seminars in my studies and consider it a core topic connected both to science and to digital environments. Normative and feminist social theory, as well as the theory of science and phenomenology, are all brought to me through seminar formats at university and made up a good part of my education there. I find it hard to properly demonstrate what interests me without presenting often long-winded and dull term papers. The courses I loved most also often had a format with a weekly hand-in, where students are asked to comment on the paper they just read to identify points to carry into next week's discussion. I am incredibly thankful for this methodology of approaching complex philosophical works, often complete books with supplicant essays surrounding the course topic. In my opinion, nearly all of the value created during these seminars is contained within the live discussions fed by reading materials and little opinion pieces in the form of forum comments. That's why I decided to share here a selection of these weekly commentaries and the sources they are based upon. They are often unrefined and informal, but they indicate the centerpiece of the seminars and demonstrate many thought processes that happened within me during these sessions. Although I took only a small selection, in sum they are a substantial read. Feel free to just skip through and read what catches your interest.
Forum entries from the Seminar: Critical Epistemologies
On Anderson: Institutions
Note
Source Text: Epistemic Justice as a Virtue of Social Institutions Elizabeth Anderson (2012) Epistemic Justice as a Virtue of Social Institutions, Social Epistemology, 26:2, 163-173, DOI: 10.1080/02691728.2011.652211 Publication
The text by Anderson helped shed light on a few issues I stumbled over with Frickers Account. On top of the various issues I and seemingly others have with her virtue-based approach, I think a utilitarian angle is worth considering. That would be: okay, I accept that people can help fight injustice by realising their privilege, showing restraint, silencing themselves, and adopting the benevolent listening approach. I think that is a practical, virtuous, and realistic endeavour. But is it the effective path to alleviating structural injustice? I think not, and initially, that is a major reason I discarded Fricker’s approach, although I saw merit. I have similar concerns to Anderson in the scalability of virtues. Virtuous behavior might help my personal well-being, it gives me normative elevation and might even further the quality of relationships I have. But is it applicable to society, is it enough to counteract structural injustice? Well, maybe, assuming that:
Everyone realizes their privilege,
Everyone concludes that justice is the right goal,
Upon deciding to adopt a virtuous stance, everyone at least moderately succeeds in practicing what they preach.
I think, for society, the same society that came up with patriarchy in the first place, external pressure, some measure independent of the convictedness of the subjects is needed. Anderson made the powerful point of: “Anything that works, goes”, which took me some time to appreciate. I am always angry when I get told to keep my shower to a minimum or stop using plastic straws when I know exactly that my using less water is nothing compared to the institutionalized practice of Coca-Cola putting water into bottles. I feel like it is unjustified to ask me to save water while others triple their output, for performance. The same thing applies to Epistemic injustices. It strikes me how much energy it costs to keep up virtuous behavior individually and how little effect there is to show for it. I do not believe in “trickling up” where institutions will eventually adopt individual practices. Is Fricker thereby less right in her point? No, it adds up, as an entire population showering shorter adds up to lots of water saved. Anderson also points out how locally innocent biases can create injustice on a “macro” scale. Another indicator for me is that local virtue is not the sole solution, as it can still feed and sustain a system enforcing epistemic injustice.
I still have doubts about what to do now with my ideas, on how the world looks that I want. I lack the imagination of seeing a world that is epistemically just, and it is hard to strive for something one cannot even imagine. The system is inherently leaning toward inequality, if I try to balance something on a needle, it will only go well so long, before small imbalances create chain reactions and the object should be called unstable. Should we even succeed in “resetting” society, creating equal participation for each subject, how will it remain just? Is Justice always a conjunct of Equality? Are there ways to achieve real Justice without needing equality?

On Medina, the informant and the inquirer
Note
Source Text: Dr. José Medina (2012) Hermeneutical Injustice and Polyphonic Contextualism: Social Silences and Shared Hermeneutical Responsibilities, Social Epistemology, 26:2, 201-220, DOI: 10.1080/02691728.2011.652214 Publication
My biggest takeaway here was that, as I tried to hint at in an earlier comment, Whenever we talk about justice, this necessarily refers to a relational concept, where everybody has a double role to ensure successful communication. Medina calls these the inquirer and the informant. So, every individual has to make sure to act to her capacity as an epistemologically sound knowledge-acquiring agent (the inquirer). This would involve knowing when and how to falsify/qualify statements, making inferences about the theory of mind, and generally comparing different statements. The other role is the informant, where the individual should have the capacity to function as an object in an inquiry by another. Very roughly this can, I think, be compared to any good communication model, where there are a listener and a speaker, and both have to function. What was new here, or at least came out more clear is that it not only depends on the capacity of both of these roles on the subject, but it is also directly dependent on the “other”, the agent opposite of the subject. We may call this other society later but it helps me to visualize the other as an individual nonetheless. Where the analogy to communication now fails, in my opinion, is this cross-dependence, where an agent does not fully determine her capacity to act both as an inquirer and as an informant, it is co-determined by the “other”. So, if I, as an “other”, listen to someone's statements, and I fail or refuse to understand the epistemic content of the message, I am not only impairing my epistemic agency, but I also hurt the epistemic agency of the subject. Maybe obvious to most, but this thought struck me as being exactly the point of leverage for dysfunctionalities in power relations. Also argued convincingly in the paper was that these are distinct and independent agencies, which can be impairing an individual separately. Overall, the Medina text was incredibly helpful after the somewhat confusing Fricker text that felt incomplete and left a lot of questions for me. The medina text picked up all my initial doubts, that I couldn't properly formulate, and many more, while still holding to the general framework of Fricker. Although I was not convinced by the Fricker Text, I tend to think the strategy:
"When in doubt, give the subject full epistemic credibility"
Is a good strategy that might alleviate a lot of issues regarding functions of power, and hierarchy, but also further, it might be a good counter for things as our confirmation bias, expectation bias and many individual errors that we could minimize by constantly exposing ourselves to falsifiability through others (voluntarily). Sounds like science applied to agency to me.

On Jaggar: Norms, Outlaw Emotions, and the Ideal Society
Note
Source Text: Alison M. Jaggar (1989) Love and knowledge: Emotion in feminist epistemology, Inquiry, 32:2, 151-176, DOI: 10.1080/00201748908602185 Publication
I found Jaggar to be a very wholesome read, it was the perfect amount of grounded argumentative structure and felt very connected as a whole. This was, together with the ideas from Lugones the best and most fruitful paper for me. On outlaw emotions: First, I hate the term, I think it’s placative and fails to frame the (actually nice) idea behind it. Outlaw Emotions are all those emotions incompatible with the dominant norms. That’s a huge field to cover, among feminist emotions they would also encompass emotions that are irrational or “faulty”. So, Jaggar does the term Justice by saying, some, but not all Outlaw Emotions are Feminist emotions. To make this evident, just think of a murderer's joy for killing, it is of no feminist interest to dissect, yet it is against dominant values. So, experiencing Outlaw emotions is a (probably) necessary, but not sufficient condition for feminism. The incompatible emotion serves to create discourse and change. Jaggar convincingly shows how emotions have a direct influence on beliefs and can validly constitute evidence, while simultaneously validly influencing values in a similar manner. When we talk about dominant/alternative norms, we already endorse hierarchy in society. We acknowledge its existence, simply by identifying the dominant norm. I am not quite sure what exactly Jaggar proposes we should do with the hierarchy structures in society. Explicitly I can read: Subcultures rejecting dominant norms should be formed, to create counterbalances and a somewhat fair discourse over the topic. “How can we determine which outlaw emotions are to be endorsed or encouraged and which rejected? In what sense can we say that some emotional responses are more appropriate than others? What reason is there for supposing that certain alternative perceptions of the world, perceptions informed by outlaw emotions, are to be preferred to perceptions informed by conventional emotions? Here I can indicate only the general direction of an answer, whose full elaboration must await another occasion. I suggest that emotions are appropriate if they are characteristic of a society in which all Human Life (and perhaps some nonhuman life, too) thrive, or if they are conducive to establishing such a society.” To me this passage sounds sketchy at best, there is no indication of how to successfully separate appropriate from inappropriate emotions. Roughly, I read this part as: emotions are warranted iff they increase the balance of power. (equivalent to minimizing the height of the hierarchy) I would love to get to read this “other occasion” because it seems indefensible to me to formulate a norm that states: Accept only emotions which eliminate/diminish norms. The idea roughly resembles Rawls's Minimax Principle, where a policy should be implemented iff the benefit for the most disadvantaged is highest. Another thing I found helpful is her reformulation of what norms do: “Dominant Norms tend to serve dominant interests” til here nothing new, this is a tautology for me, I understand norms as identical to dominant interests, that’s literally what norms are. Is an alternative, suppressed norm even thinkable? Isn't it inherent in a norm that it be the dominant one? But then, after that: "Whatever our color / gender / class / sexual orientation, we are likely to adopt the dominant value of racist, classist, homophobe, misogynistic white men." This was rather helpful to me, as it reframes the “act” of oppression as the “likelihood of value distribution” being skewed in your favor, making everybody’s values more likely to be similar to yours. This nicely illustrates how a system can be hierarchical and oppressive, without anybody actively, intentionally “acting oppressive”, while still perpetuating oppression. I'm not saying everybody is acting unintentionally oppressive, but it is always hard to imagine for me to picture "White Men" forming a group and collectively deciding on who to hate this coming season, Conceptually separating "being oppressed" and "oppressing" into phenomena without necessary inherent causal relation makes sense to me here.

Forum entries from the Seminar: Critical Philosophy of Subjectivity 1: Michel Foucault
On Butler: Constituting norms =/= carrying normative responsibilities for their existence
Citation from Butler, Page 51, citing Ewald, which is, in turn, interpreting Foucault:
The norm integrates anything which might attempt to go beyond it—nothing, nobody, whatever difference it might display, can ever claim to be exterior, or claim to possess an otherness which would actually make it other” (Norms, Discipline, and the Law, P.173)
Such a view suggests that any opposition to the norm is already contained within the norm, and is crucial to its functioning.
Here, for me, the entire futility of the approach later identified and described is condensed into a few sentences.
Hence, regulations that seek merely to curb certain specified activities (sexual harassment, welfare fraud, sexual speech) perform another activity that, for the most part, remains unmarked: the production of the parameters of personhood, that is, making persons according to abstract norms that at once condition and exceed the lives they make—and break. Page 56, final sentence
The idea that it is impossible to legislatively regulate norms without propelling, propagating, and carving them out deeper resonates with me, but at the same time, it has left me undecided on how to proceed. I understand the first citation to clearly be Ewald's interpretation of things and am not sure whether Foucault's careful circumvention of the term "Norms" is related to anticipation of this argument.
Further, I am not sure I share Ewald's interpretation; I see that the object "othered" by a norm is a constituent and necessary object for the norm, simply due to its "comparative" nature (p. 51, citation from Ewald). The oppressed may well be as constituting of norms as the privileged, but this does not translate to a normative responsibility nor a pang of guilt in my opinion. The dangerous argument that the oppressed bear responsibility for their situation is too close for my taste. I would like to emphasize a clear cut between constituting and reinforcing a norm and thriving on it. Yes, maybe that is a good location to make the cut: The normative and ethical pressure, or better, the guilt of complicity lies with the ones thriving BECAUSE of a norm and clearly not with those thriving DESPITE OF a norm. I would think that Butler makes a similar argument elsewhere, but as such, I was missing it here, resulting in a very bleak and hopeless situation where any struggle to change the status quo through legislation is doomed and inevitably propagates and reinvents stable unfair relations of power.

Some tiny details about norms that stuck out to me about the norm were that: 1: they are fictional and thus, an object conforming to a norm is not more meaningful than an object not conforming to a norm. 2: the entire given set comprises the norm, the deviations play a defining role in the formation of the norm itself (or an average). p. 152: Under norm, 3 phenomena are subsumed: Discipline, less as a constraint, but more as a regulatory mechanism insurance, Reducing objects to their relative occurrence, distributing risk. and standardization. The norm has three defining features:
positivism, as reliant on facts, which have an aura of objectivity around them.
relativity, they are neither absolute nor universal, they have a scope, both in definition as a certain temporal extension.
polarity involving a classification between the normal and the abnormal, where the abnormal is to be some handicap, not attaining something that the normal does attain.
What, then, is a norm?
It is a way for a group to provide itself with a common denominator in accordance with a rigorous principle of self-referentiality, with no recourse to any kind of external reference point, either in the form of an idea or an object. The normative process can obey a variety of different logics: the panoptical logic of discipline, the probabilistic schema of insurance, or the communicative logic of the technical norm. These three logics have the same form: in each case, the rule which serves as a norm, by virtue of which everyone can measure, evaluate, and identify himself or herself, will be derived from those for whom it will serve as a standard. A strange logic, this, which forces the group to turn back in upon itself and which, from the moment it establishes itself, will let no one escape its purview. p. 154

one finds all sorts of support mechanisms [...] which invent, modify and re-adjust, according to the circumstances of the moment and the place- so that you get a coherent, rational strategy, but one for which it is no longer possible to identify a person who conceived it. p. 203
In this passage, and the one following it, I think Foucault pinpoints as one of the central attributes of the apparatus (or dispositif) the arbitrariness of the order of power relations. There is no identity having to undergo some sort of inventive process to start off a collective change, a "strategy" just happens to meet the criteria for deployment.
But between the strategy which fixes, reproduces, multiplies and accentuates existing relations of forces, and the class which thereby finds itself in a ruling position, there is a reciprocal relation of production. Thus one can say that the strategy of moralising the working class is that of the bourgeoisie. One can even say that it's the strategy which allows the bourgeois class to be the bourgeois class and to exercise its domination. But what I don't think one can say is that it's the bourgeois class on the level of its ideology or its economic project which, as a sort of at once real and fictive subject, invented and forcibly imposed this strategy on the working class.
This was for me the most powerful grasp of what an apparatus is. A complicated removal of the effector from the effect. I struggle to continue to find any substance to the relations of the classes. Does reciprocal mean anything more than both are constitutive of each other? One produces the means of reproduction of the other, but where exactly can I apply moral judgements? This whole ordeal and now I lack subjects to blame. How can this theory possibly bring about change in society? Is that even its goal? Do we undergo this analysis in order to make society better in the end?

Forum entries from the Seminar: Is political violence justifiable? Reading Judith Butler and Elsa Dorlin
From the seventh chapter in Dorlins "Self-Defense", I found the idea that safe spaces are actually prone to be counterproductive very strong. I think the discussion around whether safe spaces are an effective tool that is appropriate on top is a rather current and ongoing one. In so many other words, Dorlin here opens up the idea that the creation of a safe space always implies a hostile "outside" or other space. Further, Dorling sees as problematic that safe spaces will often experience problematic situations when trying to self-govern. The line of thought here is that safe spaces often explicitly reject the authority of traditional state bodies, since those exactly are identified as the oppressive force. This is problematic because then the community inside the safe space has to recreate social norms from scratch and qua definition of a safe space end up being much more restrictive and monitoring, tapping also into potentially extreme measurements for "enforcing" safety. Dorlin notes that by doing this, societal oppressive norms can end up becoming reproduced through the very instance created to shelter from it. I think this opens up 2 points worth discussing: Are there limits to the self-governance of leftist groups? How can self-governance be made possible without recreating some hierarchy or other? Does this ignore that safe spaces can sometimes be essential for survival? According to Dorlin, the alternative seems to be to instead of building sheltered, isolated safe spaces, the fight has to occur in the public, transforming the entire space without the necessity for exclusive logic. How can we argue this? Could there be an oppressed position from whence any aggressive stance towards the public forbids itself? (I think there is!) For me this seems like putting the entire burden of transformational potential on the oppressed individual, enabling a position like: "Well, the person did not object or introduce change, so the person implied consent." Will a public fight cause more harm being fought than it will save after introducing change? And who are we to calculate this beforehand?

Worin unterscheiden sich inferentialistische von nicht-inferentialistischen Theorien der testimonialen Erkenntnis (d.h. des Wissens durch das Zeugniss andere)?
Inferentialistische Theorien gehen davon aus, dass die eigentliche Inferenz, also die Generierung eines neuen Epistems im Subjekt stattfindet. Konkret heisst dass, dass Ich die Aussage P einer dritten Person erst in irgendeiner Weise vor mir selbst rechtfertigen muss, bevor ich sie selbst verwenden kann. Ist die Aussage nun 2 + 2 = 4, muss ich also mit allen mir zur Verfügung stehenden Mitteln selbst überprüfen, ob diese Aussage Wahrheits- und Kohärenzkriterien erfüllt. Ich muss also beispielsweise über darunterliegende Axiome, die mir bekannt sind, die Aussage extern (ausserhalb von Person X hat das gesagt, also kann Ich das glauben) überprüfen. Im simplen Beispiel also konkret das Ergebnis berechnen. Wenn man so will, liegt also immer die “Beweislast” für meine eigenen Episteme bei mir und ich kann diesen Beweisaufwand nur begrenzt auslagern. Eine sehr direkte Folge davon wäre, dass jeglicher Erkenntnisgewinn mit erheblicher, bewusster oder unbewusster Arbeit verbunden ist. Dies wäre die wahrscheinlich logisch stringentere Theorie, gegen sie spricht aber die Phänomenologie eines Erkenntisgewinns. Eine Erkenntnis kommt uns oft vor wie ein “Heureka” Moment, wir “finden” sie, plötzlich ist sie da und wir können mit ihr arbeiten. Eine nicht-inferentialistische Theorie legt ebendiese Beweislast nicht im Subjekt an, ich habe eine Erlaubnis, oder besser, ein Recht auf a-priori Annahme der Richtigkeit der Aussage. “Person X hat mir P gesagt, also kann ich P verwenden” ist nun valide und bedarf erstmal keiner weiteren Überprüfung auf Richtigkeit. Diese Argumentationslinie ist deutlich kompatibler mit der phänomenologischen Erfahrung einer Erkenntnis vim Alltag. Wir stoßen aber auf deutlich größere Probleme, wenn wir uns fragen, woher eigentlich unser Recht auf Wahrheitsannahme von Drittaussagen kommt. Klar, 2+2=4, weil der Prof das an die Tafel geschrieben hat, ist die “schlechtere” Begründung als zu sagen, dass das Ergebnis aus gewissen mathematischen Axiomen deduziert wurde.
Formulieren Sie jeweils einen Einwand gegen beide Theorien.
Wir befinden uns also nun in der Spannung der phänomenalistischen “Heureka” Erfahrung des Findens von Epistemen (in nicht-inferentiellen Systemen) und dem Problem der schwachen Justifizierung von Aussagen gegenüber der erhöhten Stringenz eines epistemischen Systems, dass externe (logische, probabilistische, normative etc.) Gründe für Aussagen zur Verfügung stellt, aber einen schier unüberwindbaren rechnerischen Aufwand darstellt. Auch das Problem der ersten Begründung bleibt bestehen. Angenommen, ich weiß noch nichts, habe bisher null Episteme gesammelt, wie wird das erste Epistem, das ich finde, begründbar sein?
Worin besteht doxastische Verantwortung (doxastic responsibility) nach F und Ihrer eigenen Meinung nach.
Doxastische Verantwortung ist die Verantwortung für die Begründbarkeit des eigenen Nezwerkes aus Epistemen. Wenn mich also jemand fragt: Warum glaubst du das?, ist es sozial im Allgemeinen erwartbar, dass ich darauf eine Antwort liefern kann. Und wie wir eben schon am Beispiel der Begründung für 2+2=4 gesehen haben, scheint es hier “bessere” und weniger gute Gründe zu geben, das heisst, eine Person kann zur Verantwortung gezogen werden, unzureichend begründete Episteme fallen zu lassen und eine gewisse Grenze zu ziehen, eine mindest erwartbare Begründung. Diese kann sehr wahrscheinlich nicht universell formuliert werden. Eine Regel wie: Alle Bürger dürfen nur noch Aussagen weiterverwenden, denen sie eine mindestens 90-prozentige Wahrheitswarscheinlichkeit attestieren, ist aus diversen Gründen problematisch. Frickers Auffassung Doxastischer Verantwortung ist insofern speziell, als dass sie eine deutliche Verbindung moralischer Verantwortung (die wir offensichtlich alle in irgendeiner Form tragen) und Doxastischer Verantwortung sieht. Sogar die Gründe sind oft überlappend. Eine Gute Moralische Begründung, die zum Beispiel der Wahrhaftigkeit, scheint ganz offensichtlich auch eine gute doxastische begründung zu sein. Diese Parallelität zieht Fricker heran, um neo-aristotelianische Moralbegründuungen auch auf epistemischer Ebene wirksam zu machen. Ich lasse mich da gern Überzeugen von Ihr und erache es als sinnvoll Doxastische Verantwortung in gewisser Weise moralisch bindend zu machen. Intuitiv wissen wir ja auch, dass unsere Erwartung, dass dritte wahrhaftig mit uns interagieren, auf Gegenseitigkeit beruht und das leben nicht nur normativ, sondern auch auf epistemischer Ebene “verbessert”. Dies liefert auch eine recht simplistesche Rechtfertigung, annehmen zu können, dass Dritte mir die Wahreit sagen. Ich tue ja auch immer mein Bestes, warum also die anderen nicht?

-Plastic Recycling - Aron Petau
Being involved with 3D Printers, there is the issue of sustainability that I am confronted with regularly. Most 3D printed parts never get recycled and add to the global waste problem, rather than reducing it. The printer most certainly doesn’t care what it is printing, the main problem is the dimensional accuracy and the purity of the material. All of this leads to a huge industry, Germany being especially involved, using loads of virgin plastic.
What can be done about it? We can design our products to last longer, we can also print recycling labels on them so they do not have to get burned after their first life. We can take care to only print functional objects, not just fun toys nobody uses. Yet, none of that prevents the use of virgin plastics. If you buy a spool of filament, there are some recycled options, but usually at twice the price at worse quality. No wonder recycled filament fails to convince the masses. It is mostly a fun thing YouTubers can pursue, not a valid commercial process.
In my opinion, the core problem is the nonexistent economic feasibility of a proper recycling process. Identifying the exact material of a piece of trash is a very hard problem, definitely not solved yet. So why do we mix the plastic up in the first place? There is a general willingness of people to recycle, but the system for it is missing.
The Master Plan
I want to get people to wash and separate their trash for me, which are the most expensive steps in the recycling process. There is a willingness to take the extra step, and even if just my mom collects bottle caps for me, that is more than I can realistically use up. This only really works when I am thinking in a local and decentral environment. The existing recycling facilities clearly will not be able to provide 200 different containers for 200 different types of plastic. Starting the process with clean and sorted materials, like bottle caps (HDPE) or failed prints (PET-G), I start off with an advantage. Now I have to take apart the trash into evenly sized particles. Meet:
The Shredder
We built the Precious Plastic Shredder!
With these awesome open-source drawings, I was able to cobble together my very own very dangerous plastic shredder.
After finding some way to drive this massive axis, I feed the beast and hopefully get tiny pretty uniform plastic bits that are ready to begin the cycle of life anew.
The solution for the motorization was an old and used garden shredder that still had an intact motor and wiring. We cut it in half and attached it to the shredder box.
After replacing the weak force transmission screw for an industrial coupler, we were ready to try it out. Obviously, there are still security concerns in this prototype, a proper hopper is already being made.
Nevertheless, we are confident that this shredder will be able to deal with the light sorts of plastic we are thinking of. As you can see, I am now able to produce awesome confetti but to do more with the plastic flakes I have to extrude them.
Meet the Filastruder
This is the Filastruder, designed and made by Tim Elmore, in an attempt to create the cheapest viable way to extrude plastic. The biggest cost issue is the tight industrial tolerances in thickness that have to be adhered to. This is in essence what separates good from the bad filament. The industry standard nowadays is at +-0.03mm. Hard to achieve on a DIY setup, but not unheard of. The setup, like any bigger industry equivalent, consists of a motor pressing plastic pellets through a heated screw, extruding molten plastic at the end through a nozzle, and setting the diameter. The leftmost machine is responsible for winding the filament properly onto a spool.
Here you can see the extrusion process in action.
The Filastruder is controlled by an Arduino and is highly configurable. The laser sensor visible in the video is already working, but I am missing more direct control over the diameter of the filament.
When it all really comes down to the single variable of the filament diameter responsible for the quality of my recycled project, a simple Machine Learning optimization directly jumps at me: I have a few variables like winder speed, extrusion speed, heat, and cooling intensity. These variables can be optimized on the fly for an exact diameter. This is actually roughly how virgin filament is produced, commercial facilities just manage much faster.
So far, I am aware of a few companies and academic projects attempting this process, but none of them manage to get either the quality or the price of other products available. Automatization does not just take out jobs away, I think it can also be a helpful tool, for example tackling environmental issues such as this one.
This project is very dear to my heart and I plan to investigate it further in the form of a master thesis. The realization will require many skills I am already picking up or still need to work on within the Design and Computation program. {: .notice--info}

-Postmaster - Aron Petau
Emails are a wondrous thing and I spend the last weeks digging a bit deeper in how they actually work. Some people consider them the last domain of the decentralized dream the internet once had and that is now popping up again with federation and peer-to-peer networks as quite popular buzzwords.
We often forget that email is already a federated system and that it is likely the most important one we have. It is the only way to communicate with people that do not use the same service as you do. It has open standards and is not controlled by a single entity. Going without emails is unimaginable in today's world, yet most providers are the familiar few from the silicon valley. And really, who wants their entire decentralized, federated, peer-to-peer network to be controlled by a schmuck from the silicon valley? Mails used to be more than that and they can still be. Arguably, the world of messanging has gotten quite complex since emails popped up and there are more anti-spam AI tools that I would care to count. But the core of it is still the same and it is still a federated system. Yet, also with Emails, Capitalism has held many victories, and today many emails that are sent from a provider that does not belong to the 5 or so big names are likely to be marked as spam. This is a problem that is not easily solved, but it is a problem that is worth solving.
Another issue with emails is security, as it is somehow collectively agreed upon that emails are a valid way to communicate business informations, while Whatsapp and Signal are not. These, at least when talking about messaging services with end-to-end encryption, are likely to be way more secure than emails.
The story
So it came to pass, that I, as the only one in the family interested in operating it, "inherited" the family domain petau.net. All of our emails run through this service, that was previously managed by a web developer that was not interested in the domjobain anymore.
With lots of really secure Mail Providers like Protonmail or Tutanota, I went on a research spree, as to how I would like to manage my own service. Soon noticing that secure emails virtually always come with a price or with lacking interoperability with clients like Thunderbird or Outlook, I decided to go for migadu, a swiss provider that offers a good balance between security and usability. They also offer a student tier, which is a big plus.
While self-hosting seems like a great idea from a privacy perspective, it is also quite risky for a service that is usually the only way for any service to recover your password or your online identity. Migadu it was then, and in the last three months of basically set it and forget it, i am proud to at least have a decently granular control over my emails and can consciously reflect on the server location of The skeleton service service that enables virtually my entire online existence.
I certainly crave more open protocols in my life and am also findable on Mastodon, a microblogging network around the ActivityPub Protocol.

3D Printing
3D Printing is more than just a hobby for me
In it, I see societal changes, the democratization of production, and creative possibilities. Plastic does not have to be one of our greatest environmental problems if we just choose to change our perspective and behavior toward it. Plastic Injection molding was one major driving force for the capitalist setting we are in now. 3D Printing can be utilized to counteract the production of scale. Today, the buzzword 3D Printing is already associated with problematic societal practices, it is related to "automatization" and "on-demand economy". The technology has many aspects to be considered and evaluated and as a technology, many awesome things happen through it and on the same page it fuels developments I would consider problematic. Due to a history of patents influencing the development of the technology, and avid adoption of companies hoping to optimize production processes and margins, but also a very active hobbyist community, all sorts of projects are realized. While certainly societally explosive, there is still a lot going for 3D Printing.
3D Printing means local and custom production. While I do not buy the whole “every household is going to have a machine that prints what they need right now at the press of a button”, I do see vast potential in 3D Printing. That’s why I want to build my future on it. I want to design things and make them become reality. A 3D Printer lets me control that process from start to finish. Being able to design a thing in CAD is not enough here, I also need to be able to fully understand and control the machine that makes my thing.
I started using a 3D Printer in early 2018, and by now I have two of them and they mostly do what I tell them to do. I built both of them from kits and heavily modified them. I control them via octoprint, a software that, with its open and helpful community, makes me proud to use it and taught me a lot about open-source principles. 3D Printing in the hobbyist space is a positive example where a method informs my design and I love all the areas it introduced me to. Through it, I felt more at home using Linux, programming, soldering, incorporating electronics, and iteratively designing. I love the abilities a 3D Printer gives me and plan on using it for the recycling project.
During the last half year, I also worked in a university context with 3D printers. We conceptualized and established a "Digitallabor", an open space to enable all people to get into contact with innovative technologies. The idea was to create some form of Makerspace while emphasizing digital media. The project is young, it started in August last year and so most of my tasks were in Workgroups, deciding on the type of machines and types of content such a project can provide value with. Read more about it on the Website:
Looking forward, I am also incredibly interested in going beyond polymers for printing. I would love to be able to be more experimental concerning the material choices, something rather hard to achieve while staying in a shared student flat. There have been great projects with ceramics and printing, which I certainly want to have a deeper look into. One project I want to highlight is the evolving cups which impressed me a lot.
This group from the Netherlands is algorithmically generating shapes of cups and then printing them on a paste extruder with clay. The process used is described more here:
The artist Tom Dijkstra is developing a paste extruder that can be attached to modify a conventional Printer and I would very much love to develop my version and experiment with printing new and old materials in such a concept printer.
Also with regards to the recycling project, it might make sense for me to incorporate multiple machines into one and let the printer itself directly handle pellet- or paste-form. I am looking forward to expanding my horizon there and seeing what is possible.
Cups and Tableware are of course just one sample area where a backtrack toward traditional materials within modern manufacturing could make sense. There is also more and more talk of 3D Printed Clay- or Earth homes, an area where WASP is a company I look up to. They built several concept buildings and structures from locally mixed earth, creating some awesome environmentally conscious structures.
Adhering to principles of local building with locally available materials and taking into account the infamous emission problem within the building industry has several great advantages. And since such alternative solutions are unlikely to come from the industry itself, one major avenue to explore and pursue these solutions are art projects and public demonstrations.
I want to explore all these areas and look at how manufacturing and sustainability can converge and create lasting solutions for society.
Also, 3D Printing is directly tied to the plans for my master's thesis, since everything I manage to reclaim, will somehow have to end up being something again. Why not print away our waste?
Now, after a few years of tinkering, modifying and upgrading, I find that I did not change my current setup for over a year. It simply works and I am happy with it. Since my first beginner's printer, the failure rates are negligible and I have had to print really complex parts in order to generate enough waste for the recycling project. Gradually, the mechanical system of the printer shifted from an object of care to simply a tool that I use. In the last years, hardware, but especially software has matured to a point where, at least to me, it tends to be a set-and-forget situation. On to actually making my parts and designs.

Ruminations
By Aron Petau and Niels Gercama • 2 minutes read •
was a contemplation on data privacy at Amazon. It asks how to subvert browser fingerprinting and evading the omnipresent tracking of the consumer.
The initial idea was to somehow, by interacting with the perpetrator and letting data accumulate that would degrade their knowledge and thereby destroy predictablity, making this particular dataset worth less.
We could have just added a random clickbot, to confuse things a bit and make the data less valuable. But looking at todays state of datacleanup algorithms and the sheer amount of data that is collected, this would have been a futile attempt. Amazon just detects and removes any noise we add and continues to use the data.
So, then, how can we create coherent, non-random data that is still not predictable?
One answer that this concept should demonstrate, is by inserting patterns that amazon cannot foresee with their current algorithms. As if they were trying to predict the actions of a person with shizophrenia.
The Concept
It consists of a browser extension (currently Chrome only) that overlays all web pages of Amazon with a moving entity that tracks your behavior. While tracking, an image classifier algorithm is used to formulate a product query off of the Storefront. After computation, a perfectly fitting product is displayed for your consumer's pleasure.
The analogue watchdog
A second part of the project is a low-tech installation consisting of a camera (we used a smartphone) running a computer-vision algorithm tracking tiny movements. This was then pointed towards the browser console in the laptop running the extension. The camera was then connected to a screen that displayed the captured image. The watchdog was trained to make robot noises depending on the type and amount of movement detected. Effectively, whenever data traffic beween amazon and the browser was detected, the watchdog would start making noises.

-Sferics - Aron Petau
A radio atmospheric signal or sferic (sometimes also spelled "spheric") is a broadband electromagnetic impulse that occurs as a result of natural atmospheric lightning discharges. Sferics may propagate from their lightning source without major attenuation in the Earth–ionosphere waveguide, and can be received thousands of kilometres from their source.
Microsferics is a nice reference Project, which is a network of Sferics antennas, which are used to detect lightning strikes. Through triangulation not unlike the Maths happening in GPS, the (more or less) exact location of the strike can be determined. This is useful for weather prediction, but also for the detection of forest fires, which are often caused by lightning strikes.
Because the Frequency of the Sferics is, when converted to audio, still in the audible range, it is possible to listen to the strikes. This usually sounds a bit like a crackling noise, but can also be quite melodic. I was a bit reminded by a Geiger Counter.
Sferics are in the VLF (Very Low Frequency) range, sitting roughly at 10kHz, which is a bit of a problem for most radios, as they are not designed to pick up such low frequencies. This is why we built our own antenna. At 10kHz, we are talking about insanely large waves. a single wavelength there is roughly 30 Kilometers. This is why the antenna needs to be quite large. A special property of waves this large is, that they get easily reflected by the Ionosphere and the Earth's surface. Effectively, a wave like this can bounce around the globe several times before it is absorbed by the ground. This is why we can pick up Sferics from all over the world and even listen to Australian Lightning strikes. Of course, without the maths, we cannot attribute directions, but the so called "Tweeks" we picked up, usually come from at least 2000km distance.
The Build
We built several so-called "Long-Loop" antennas, which are essentially a coil of wire with a capacitor at the end. Further, a specific balun is needed, depending on the length of the wire. this can then directly output an electric signal on an XLR cable.
Loosely based on instructions from Calvin R. Graf, We built a 26m long antenna, looped several times around a wooden frame.
The Result
We have several hour-long recordings of the Sferics, which we are currently investigating for further potential.
Have a listen to a recording of the Sferics here:
As you can hear, there is quite a bit of 60 hz ground buzz in the recording. This is either due to the fact that the antenna was not properly grounded or we simply were still too close to the bustling city. I think it is already surprising that we got such a clear impression so close to Berlin. Let's see what we can get in the countryside!

-Stable Dreamfusion - Aron Petau
I forked a really popular implementation that reverse engineered the Google Dreamfusion algorithm. This algorithm is closed-source and not publicly available. The implementation I forked is here This one is running on stable-diffusion as a bas process, which means we are are expected to have worse results than google. The original implementation is here
Gradio
The reason i forked the code is so that i could implement my own gradio interface for the algorithm. Gradio is a great tool for quickly building interfaces for machine learning models. No code involves, any user can state their wish, and the mechanism will spit out a ready-to-be-rigged model (obj file)
Mixamo
I used Mixamo to rig the model. It is a great tool for rigging and animating models. But before everything, it is simple. as long as you have a model with a decent humanoid shape in something of a t-pose, you can rig it in seconds. Thats exactly what i did here.
Unity
I used Unity to render the model to the magic leap 1. Through this, i could create an interactive and immersive environment with the generated models.
The dream was, to build a AI- Chamber of wishes. You pick up the glasses, state your desires and then the algorithm will present to you an almost-real object in AR.
Due to not having access to the proprietary sources from google and the beefy, but still not quite machine-learning ready computers we have at the studio, the results are not quite as good as i hoped. But still, the results are quite interesting and i am happy with the outcome. A single generated object in the Box takes roughly 20 minutes to generate. Even then, the algorithm is quite particular and oftentimes will not generate anything coherent at all.

Studio UMZU has launched
By Aron Petau and Friedrich Weber Goizel • 1 minute read •
We’ve started a new project together: Studio UMZU.
Together with Friedrich Weber Goizel, I founded the studio to bring more workshops into libraries, schools, and other public places. Our goal is to make access to digital fabrication, robotics, and creative technologies as easy as possible for you – flexible, low-threshold, and always with the joy of experimenting.
On our website you’ll find more about us, our workshop formats, and how we support libraries in building makerspaces: studio-umzu.de.
We’re really excited that things are officially kicking off – maybe soon at your place too!

Klasse. Der Kurs bietet einen spielerischen und begleiteten Einstieg in die Welt der Elektronik, des Lötens und der digitalen Gestaltung. Im Mittelpunkt steht das Verstehen durch eigenes Machen: Technologien begreifen, indem man sie selbst gestaltet.\nDas Projekt\nÜber drei Sitzungen hinweg (jeweils drei Stunden) entwickelten und bauten die Kinder ihre eigene USB-betriebene LED-Leuchte. Sie löteten elektronische Bauteile, modellierten Gehäuse in 3D, beschäftigten sich mit Lichtstreuung und lernten dabei ganz selbstverständlich, technische Probleme kreativ zu lösen. Jede Leuchte wurde von Grund auf gebaut, funktional und transportabel – ganz ohne Batterien, dafür mit echten Kabeln, Werkzeug und einem großen Schuss Eigenverantwortung.\nZum Einstieg lernten die Teilnehmer*innen die Grundlagen der Elektrizität mit den wunderbar zugänglichen Makey Makey-Boards kennen. Damit konnten wir spielerisch Stromkreise, Leitfähigkeit und Steuerung erklären – ein Einstieg, der sofort Neugier und Begeisterung weckte.\nAnschließend folgte das Herzstück des Projekts: USB-Kabel aufschneiden, 5V-LEDs anlöten und eigene Gehäuse entwerfen. Das Löten geschah unter Aufsicht, aber jede*r lötete selbst – und das mit sichtbarem Stolz. Wenn die eigene LED zum ersten Mal leuchtet, ist das ein magischer Moment.\nGestaltung mit Werkzeug – und mit Einschränkungen\nFür die 3D-Gestaltung nutzten wir Tinkercad auf iPads. Die Oberfläche war für viele der erste Berührungspunkt mit CAD-Software und erwies sich als zugänglich und intuitiv – allerdings nicht ohne technische Stolpersteine. Tinkercad stürzte gelegentlich ab, und Synchronisationsprobleme führten manchmal zu Verwirrung. Trotz dieser Hürden ermöglichte es einen niedrigschwelligen Einstieg in die digitale Gestaltung.\nDie entworfenen Lampenschirme mussten nicht nur schön aussehen, sondern auch die Elektronik sinnvoll aufnehmen. Dadurch ergaben sich ganz reale Designherausforderungen: Passt das Kabel? Wie weit darf die LED vom Gehäuse entfernt sein? Wie verändert sich das Licht?\nGedruckt wurde mit weißem PLA-Filament – ideal für die Lichtstreuung. Im Kurs entwickelten sich dadurch ganz organisch Gespräche über Materialeigenschaften, Lichtdurchlässigkeit und die physikalischen Grenzen des 3D-Drucks.\nEchte Herausforderungen, echtes Denken\nDas Projekt traf genau die richtige Balance: anspruchsvoll genug, um ernst genommen zu werden, aber machbar genug, damit alle ein Erfolgserlebnis hatten. Jedes Kind nahm am Ende eine funktionierende, selbstgebaute Lampe mit nach Hause – und keine glich der anderen.\nDabei gab es viele kleine Hürden: USB-Kabel, die zu viel Spiel hatten, Gehäuse, die nicht sofort passten, LEDs, die nachjustiert werden mussten. Wir wichen diesen Herausforderungen nicht aus – im Gegenteil: Wir nutzten sie als Anlässe, um gemeinsam nach Lösungen zu suchen. Gerade diese Momente führten zu den besten Gesprächen über Technik, Entwurf und Fehlerkultur.\nBonus-Runde: Tischkicker-Prototypen\nZum Abschluss durfte jede Gruppe ihren eigenen Mini-Tischkicker entwerfen – mit den Materialien und Ideen, die sie zur Verfügung hatten. Diese kreative Extra-Aufgabe förderte Teamarbeit, Improvisation und erste Design-Thinking-Schritte. Und ganz nebenbei entstanden viele lustige, kluge und überraschende Lösungen.\nRückblick\nAlle drei Durchgänge des Workshops wurden mit großem Interesse, Konzentration und Freude aufgenommen. Die Kinder waren über die gesamte Zeit engagiert, nicht nur beim Basteln, sondern auch im Denken: Wie funktioniert das? Was kann ich anders machen? Was ist möglich?\nSie gingen nicht nur mit einer leuchtenden Lampe nach Hause – sondern mit dem Gefühl, etwas selbst geschaffen zu haben. Und mit der Erkenntnis, dass Technik keine Zauberei ist, sondern etwas, das man verstehen und gestalten kann.\nAuch für uns als Kursleitung war Löten und Leuchten ein bestärkendes Erlebnis. Die Kombination aus digitalen Werkzeugen, praktischer Arbeit und offener Aufgabenstellung schuf einen Raum, in dem Lernen ganz selbstverständlich und mit echter Neugier geschah.\nLöten und Leuchten wird sich weiterentwickeln – doch das Ziel bleibt dasselbe: Kinder stärken, selbstbestimmt mit Technik umzugehen, und ihnen zeigen, dass sie mehr können, als sie denken.\n"},{"url":"https://aron.petau.net/de/project/einszwovier-opening/","title":"einszwovier: making of","body":"Die Entstehung von studio einszwovier\nAugust 2024\nWir begannen mit dem Aufbau und der Planung der Raumgestaltung sowie der Ausstattung.

It was just slow, otherwise fine. But especially using GitHub Pages imposed quite a few limitations on plugins and themes.\nAlso, maybe I didn’t put in enough effort, but I could never really get theme modifications working. Just extending the theme to show multiple authors was a pain—although it was eventually working.\nOn now finishing the master's, I wanted a visual overhaul, and while browsing for inspiration again, using Jekyll at all got questioned again.\nI knew I wanted a static site generator, because markdown is the shit.\nSo after looking around further, Zola emerged—actually through a chatbot suggestion 😄\nRecently, I made the leap to Zola, a Rust-powered static site generator, and I don't see myself going back.\n\nrust feels right\nI’ve always admired Rust for its speed, safety, and modern tooling.\nUsing a static site generator built with Rust just made sense. Zola is fast—blazing fast.\nEven during local development, rebuilds are near-instant, and that alone makes the writing process smoother and more enjoyable.\nPlus, using something written in Rust means fewer external dependencies, no bundler hell, and zero Ruby setup headaches.\nI can just download the binary, run it, and get going. It respects my time.\n\nzola is thoughtfully designed\nBeyond performance, Zola is just really well designed.\nIts template syntax (thanks to Tera) is more powerful and readable than Liquid.\nThe built-in shortcodes, pagination, and asset pipelines all feel cohesive and purposeful.\nThere’s very little “configuration over convention” fatigue that Jekyll often gave me.\nAnd even though both systems are markdown-based, migrating wasn’t just a matter of copy-pasting files.\nI had to rethink frontmatter, adjust templates, and wrangle image paths and shortcodes.\nThe structure and behavior are different enough that it felt like a real rebuild—not just a port.\n\nduckquill made me switch\nThe real catalyst, though? Duckquill, a stunning Zola theme built by Daudix.\nIt struck the perfect balance between minimalism and elegance—exactly the aesthetic I wanted but could never quite achieve with Jekyll.\nDuckquill didn’t just make Zola usable for me; it made it irresistible.\nWhat really sets Duckquill apart—beyond its clean typography and smart layout—is how well it supports a vision of digital autonomy.\nThe theme comes with Mastodon-powered comments, allowing for lightweight, federated interaction without relying on big centralized platforms.\nThis fits perfectly with my goal of reclaiming control through self-hosting.\nWhether it's running my own site, owning my content, or interacting through the fediverse, Duckquill reinforces those values rather than working against them.\nIt’s a rare example of design and infrastructure aligning with personal principles.\n\nfinal thoughts\nSwitching from Jekyll to Zola wasn’t effortless, but it was absolutely worth it.\nI now have a faster, more reliable, and better-looking site that’s easier to maintain and feels like it fits my tooling philosophy.\nIf you're feeling the weight of your current setup, maybe it's time to try Zola—and give Duckquill a spin while you're at it.\n"},{"url":"https://aron.petau.net/de/project/master-thesis/","title":"Master's Thesis","body":"Master's Thesis: Human - Waste\nPlastics offer significant material benefits, such as durability and versatility, yet their\nwidespread use has led to severe environmental pollution and waste management\nchallenges. This thesis develops alternative concepts for collaborative participation in\nrecycling processes by examining existing waste management systems. Exploring the\nhistorical and material context of plastics, it investigates the role of making and hacking as\ntransformative practices in waste revaluation. Drawing on theories from Discard Studies,\nMaterial Ecocriticism, and Valuation Studies, it applies methods to examine human-waste\nrelationships and the shifting perception of objects between value and non-value. Practical\ninvestigations, including workshop-based experiments with polymer identification and\nmachine-based interventions, provide hands-on insights into the material properties of\ndiscarded plastics. These experiments reveal their epistemic potential, leading to the\nintroduction of novel archiving practices and knowledge structures that form an integrated\nmethodology for artistic research and practice.

As you will notice in some other projects, I am quite opposed to the Idea that it should be considered normal to park ones car in the middle of the city on public spaces, for example Autoimmunitaet, Commoning Cars or Dreams of Cars.\nSo, the idea was born, to regain that space as habitable zone, taking back usable space from parked cars.\nI was gonna install a mobile workshop within a trailer.\nIdeally, the trailer should be lockable and have enough standing and working space.\nAs it turns out, Food Trailers fulfill these criteria quite nicely. So I got out on a quest, finding the cheapest food trailer available in germany.\n6 weeks later, I found it near munich, got it and started immediately renovating it.\nDue to developments in parallel, I was already invited to sell food and have the ofgficial premiere at the Bergfest, a Weekend Format in Brandenburg an der Havel, initiated and organized by Zirkus Creativo. Many thanks for the invitation here again!\nSo on it went, I spent some afternoons renovating and outfitting the trailer, and did my first ever shopping at Metro, a local B2B Foodstuffs Market.\nMeanwhile, I got into all the paperwork and did all the necessary instructional courses and certificates.\nThe first food I wanted to sell was Raclette on fresh bread, a swiss dish that is quite popular in germany.\nFor the future, the trailer is supposed to tend more towards vegan dishes, as a first tryout I also sold a bruschetta combo. This turned out great, since the weather was quite hot and the bruschetta was a nice and light snack, while I could use the same type of bread for the raclette.\n\nThe event itself was great, and, in part at least, started paying off the trailer.\nSome photos of the opeing event @ Bergfest in Brandenburg an der Havel\n\n\n\nWe encountered lots of positive feedback and I am looking forward to the next event.

Of course, without the maths, we cannot attribute directions, but the so called \"Tweeks\" we picked up, usually come from at least 2000km distance.\nThe Build\nWe built several so-called \"Long-Loop\" antennas, which are essentially a coil of wire with a capacitor at the end. Further, a specific balun is needed, depending on the length of the wire. this can then directly output an electric signal on an XLR cable.\nLoosely based on instructions from Calvin R. Graf, We built a 26m long antenna, looped several times around a wooden frame.\nThe Result\nWe have several hour-long recordings of the Sferics, which we are currently investigating for further potential.\nHave a listen to a recording of the Sferics here:\n\n\nAs you can hear, there is quite a bit of 60 hz ground buzz in the recording.\nThis is either due to the fact that the antenna was not properly grounded or we simply were still too close to the bustling city.\nI think it is already surprising that we got such a clear impression so close to Berlin.

These sounds, together make up the noise of our life, often pass by, fleeting and unnoticed.\nThe engagement with sound through active listening holds the potential to process the experience of the self and its surroundings. This is the idea of “Echoing Dimensions”: Once you engage with something, it gives back to you: Whether it is the rhythmic cadence of a heartbeat, a flowing symphony of urban activity or the hoofbeats of a running horse, minds and bodies construct and rebuild scenes and narratives while sensing and processing the sounds that surround them, that pass next and through them.\nThe exhibition \"Echoing Dimensions\" takes place at Kunstraum Potsdamer Straße gallery’s underground space and exhibits artworks by 12 Berlin based artists, who investigate in their artistic practice ‘intentional listening’ using sound, video and installation, and invites to navigate attentiveness by participatory exploration. Each artwork in the exhibition revolves around different themes in which historical ideas resonate, political-personal narratives are being re-conceptualized and cultural perspectives are examined. The exhibition's common thread lies in its interest into the complexities of auditory perception, inviting viewers to consider the ways in which sound shapes our memories, influences our culture, and challenges our understanding of space and power dynamics.\n\n2024-02-15\nWorking TD Prototype.

One particularly hands-on example is AI generated images. Within the proposed Workshop, we will dive into Explainable AI, explore Stable Diffusion, and most importantly, understand the most important parameters within it. We want to steer outcomes in a deliberate manner. Emphasis here is on open and accessible technology, to increase user agency and make techno-social dependencies and power relations visible.\nEmpower yourself against readymade technology!\nDo not let others decide on what your best practices are. Get involved in the modification of the algorithm and get surprised by endless creative possibilities. Through creating a short graphic novel with 4-8 panels, participants will be able to utilise multiple flavours of the Stable Diffusion algorithm, and will have a non-mathematical understanding of the parameters and their effects on the output within some common GUIs. They will be able to apply several post-processing techniques to their generated images, such as upscaling, masking, inpainting and pose redrawing. Further, participants will be able to understand the structure of a good text prompt, be able to utilise online reference databases and manipulate parameters and directives of the Image to optimise desired qualities. Participants will also be introduced to ControlNet, enabling them to direct Pose and Image composition in detail.\nWorkshop Evaluation\nOver the course of 3 hours, I gave an introductory workshop in local stable diffusion processing and introduced participants to the server available to UdK Students for fast remote computation that circumvents the unethicality of continuously using a proprietary cloud service for similar outputs. There is not much we can do on the data production side and many ethical dilemmas surrounding digital colonialism remain, but local computation takes one step towards a critical and transparent use of AI tools by Artists.\nThe Workshop format was rathert open and experimental, which was welcomed by the participants and they tried the collages enthusiastically. We also had a refreshing discussion on different positions regarding the ethicalities and whether a complete block of these tools is called for and feasible.\nI am looking forward to round 2 with the next iteration, where we are definitely diving deeper into the depths of comfyui, an interface that i absolutely adore, while its power also terrifies me sometimes.\n"},{"url":"https://aron.petau.net/de/project/aethercomms/","title":"aethercomms","body":"AetherComms\nStudio Work Documentation\nA Project by Aron Petau and Joel Tenenberg.\nAbstract\n\nSet in 2504, this fiction explores the causalities of a global infrastructure collapse through the perspectives of diverse characters. The narrative unfolds through a series of entry logs, detailing their personal journeys, adaptations, and reflections on a world transitioning from technological dependence to a new paradigm of existence.\nThe AetherArchive, an AI accessible via the peer-to-peer AetherComms network, serves as a conscious archive of this future, providing insights and preserving the stories of these characters.\nDisaster fiction is a genre that imagines a breakdown that highlights our social dependence on networks and the fragility of infrastructure. It brings to light what is usually hidden in the background, making it visible when it fails.\n\nThis is the documentation of our year-long studio project at the University of the Arts and the Technische Universität Berlin, exploring the power structures inherent in radio technology, the internet as network of networks and the implications of a global network infrastructure collapse.\nWe are documenting our artistic research process, the tools we used, some intermediary steps and the final exhibition.\nProcess\nWe met 2 to 3 times weekly throughout the entire year, here is a short overview of our process and findings throughout.\nSemester 1\nResearch Questions\nHere, we already examined the power structures inherent in radio broadcasting technology.\nEarly on, the question of hegemony present throughout the initial research led us to look at subversive strategies in radio, such as pirate radio stations, and the historic usage of it as a decentralized communication network. Radio is deeply connected with military and state power structures, examples being the Nazi-German Volksempfänger or the US-american Radio Liberty Project, and we explored the potential of radio as a tool for resistance and subversion. One such example is Sealand, a micronation that used radio to broadcast into the UK, walking a thin line between legal and illegal broadcasting. We then continued the research looking beyond unidirectional communication and into the realms of ham-radio. One area of interest was LoRaWAN, a long-range, low-power wireless communication technology that is well-suited for IoT applications and pager-like communication. Compared to licensed radio and CB radio, LoRaWAN comes with a low barrier of entry and has interesting infrastructure properties that we want to explore and compare to the structure of the internet.\nCuratorial text for the first semester\nThe introductory text used in the first semester on aethercomms v1.0:\n\nRadio as a Subversive Exercise.\nRadio is a prescriptive technology.\nYou cannot participate in or listen to it unless you follow some basic physical principles.\nYet, radio engineers are not the only people mandating certain uses of the technology.\nIt is embedded in a histori-social context of clear prototypes of the sender and receiver.\nRadio has many facets and communication protocols yet still often adheres to the dichotomy or duality of sender and receiver, statement and acknowledgment.\nThe radio tells you what to do, and how to interact with it.\nRadio has an always identifiable dominant and subordinate part.\nAre there instances of rebellion against this schema?\nPlaces, modes, and instances where radio is anarchic?\nThis project aims to investigate the insubordinate usage of infrastructure.\nIts frequencies.\nIt's all around us.\nWho is to stop us?\n\n\n\nThe Distance Sensors\nThe distance sensor as a contactless and intuitive control element:\n\n\n\n \n \n \n \n \n \n \n \n \n \n semester_1_process\n \n \n \n \n \n \n \n \n \n \n \n semester_1_process\n \n \n \n \n \n \n \n \n \n \n \n semester_1_process\n \n \n \n \n \n \n \n \n \n \n \n semester_1_process\n \n \n \n \n \n \n \n \n \n \n \n semester_1_process\n \n \n \n \n\nWith a few Raspberry Pi Picos and the HCSR-04 Ultrasonic Distance Sensor, we created a contactless control element. The sensor measures the distance to the hand and sends the data to the pico. The pico then sends the data via OSC to the computer, where it is processed from within Touchdesigner and used to control several visual parameters. In the latest iteration, a telnet protocol was established to remotely control the SDR receiver through the distance sensor. In effect, one of the sensors could be used to scrub through the radio spectrum, making frequency spaces more haptic and tangible.\nThe Picos run on Cirquitpython, an especially tiny version of Python specialized to play well with all kinds of hardware. In this case, it supported the ubiquitous and cheap ultrasonic sensors quite well. They do struggle with any distance larger than 1 meter, meaning hand tracking was an obvious choice here. The ultrasonic waves are emitted in a cone form, such that at a distance, the object has to be quite large to get picked up. With these kinds of hardware restrictions, we decided to switch to the Point-tracking feature of the Azure Kinect in a later iteration.\nMid-Term Exhibition\n\nThis project is an attempt to bridge the gap between the omnipresent and invisible nature of radio waves and their often-overlooked significance in our lives. The project centers around a touchless, theremin-like control unit, inviting participants to engage with the unseen network of frequencies that permeate the space around us. Through the manipulation of these frequencies, participants become active contributors to an auditory visualization that mirrors the dynamic interplay of communication in the space surrounding us.\nOur research roots in the dichotomy of radio communication—a medium that is both open and closed, inviting and elusive. Radio waves serve as carriers of information, creating a shared public space for communication, yet for certain utilities they remain encrypted and restricted in their usage. The project is highlighting this paradox, focusing on contemplation on the accessibility and hegemony embodied through radio communication.\n\n\n\nThe Midterm Exhibition 2023\n\n\n\n \n \n \n \n \n \n \n \n \n \n A Raspberry Pi Pico on a breadboard with two HCSR-04 sensors\n \n \n \n \n \n \n \n \n \n \n \n The sensor being used with hands\n \n \n \n \n \n \n \n \n \n \n \n Aron manipulating the sensor\n \n \n \n \n \n \n \n \n \n \n \n Some output from the sensor merged with audio\n \n \n \n \n \n \n \n \n \n \n \n A proposed installation setup\n \n \n \n \n\nAfter the first presentation with the Sensors, we saw no immediate productive way forward with radio frequencies. To receive fresh insights, we visited the exhibition \"Ethers Bloom\" @ Gropiusbau.\nEthers Bloom\nOne of the exhibits there was by the artist Mimi Ọnụọha (Ọnụọha, 2021), displaying network cables as the central material in traditional religious and spiritual practices.\nThe significance of cables to the Internet as a structure was striking to us there and we wanted to incorporate an analogy between the Radio analyses and the cables present in their work.\nIn the end, antennas are also just the end of a long cable.\nThey share many physical properties and can be analyzed in a similar way.\nAnother of her works, \"The Cloth in the Cable\" (Ọnụọha, 2022), displayed traditional weaving techniques with network cables. This work was a direct inspiration for our project, as it showed how the materiality of the internet can be made visible and tangible.\nFrom there, and from various feedback sessions, we decided to shift our focus from radio frequencies to the physical infrastructure of the internet. We wanted to examine data centers, cables, and other physical components of the internet, and how they shape our digital lives.\nSemester 2\nIt especially stuck out to us how the imaginaries surrounding the internet and the physical materiality are often divergent and disconnected.\nJoel developed the dichotomy of the \"Body and the Soul\" of the internet, where the body is the physical infrastructure and the soul is the immaterial and imaginary network of networks. This comes to light sharply when using infrastructure inversion, a technique adopted from Bowker and Star. Found through the research of Francis Hunger and Lisa Parks.\nFor us, this meant looking at imaginaries of the future of the internet and its collapse. Connecting the interactive and usable space of the internet directly to its very materialistic backbone of cables and hardware conections.\nIt was really fascinating, how one and the same news outlet could have wildly differing opinion pieces on how stable and secure the Metastructure of the internet was. Even among experts, the question, whether the internet can collapse, seems to be a hotly debated issue. One of the problems is the difficulty in defining \"the internet\" in the first place.\nWhat is left over in the absence of the network of networks, the internet?\nWhat are the Material and Immaterial Components of a metanetwork?\nWhat are inherent power relations that can be made visible through narrative and inverting techniques?\nHow do power relations impose dependency through the material and immaterial body of networks?\nMethods\nWe applied a variety of methods to explore the questions we posed in the first semester. Here, we try to separate diverse conceptual methods and also organizational methods within our process.\nNarrative Techniques / Speculative Design\nThrough several brainstorming sessions, and to a large extent induced by the literary and theatrical loop sessions, we discovered science fiction, climate fiction and disaster fiction as a powerful artistic tool with exploratory potential for our research. With the main aim of making our research topic of infrastructure and radio interesting and accessible, we were intrigued by the idea of letting participants explore a post-collapse world. Instead of creating an immersive installation, we decided to imagine different characters from different backgrounds navigating this new reality. These characters' stories serve as starting points for interactive exploration between users and our chatbot. Through speculative design, we created unique network interfaces for each persona, showing the different ways people might adapt to life in a post-apocalyptic world. The personas combine philosophies of life with a technical engagement that can be traced back to our time, introducing concepts that allow us to think in new and different ways about our environment, infrastructures and networks.\nWe imagined communication in this post-collapse world relying heavily on radio. Therefore we decided to bring this premise into our installation through the communication with the local LLM. Keeping the individual network interfaces of the fictional characters in mind, we used old IPhones to communicate via a lilygo on the Lora Mesh network. Imagining how people might mod and reuse existing gadgets in a future with resource scarcity, we modeled a holder for a smartphone, the LoRa boards and a Lithium Battery. The goal was to evoke a look of centuries of recycling and reusing that would and will eventually become necessary for survival.\n\nDisaster Fiction / Science Fiction\nDisaster fiction serves as an analytic tool that lends itself to the method of Infrastructure Inversion (Hunger, 2015).\nIn this case, we use a fictional approach as our narrative technique and analytical method. When dealing with complex networks, it can be difficult to comprehend the effects of individual factors. Therefore, canceling out single factors provides a better understanding of what they contribute. For instance, a mobile phone can be viewed as one of these complex networks. Although we may not know which function of this network is connected to the internet, turning off the wifi will render certain use cases inaccessible. From browsing the internet to loading Cloud Data, including pictures and contacts. Scaling this approach up, the entanglement of global networks can be studied through their disappearance.\nNon-linear storytelling\nAs a chatbot served as our narrator, it has the inbuilt restriction of being merely reactive. Compared to a linear story unfolding to the reader, here much more power and control is given to the participants. The participant can ask questions and the chatbot will answer them. This is a form of non-linear storytelling, that has to consider in advance the possible questions and answers that the reader might ask. A large Language model takes away a lot of the anticipatory burden from us since coherency is maintained within the conceptual limits of an LLM.\nFrom a narratological perspective, the chatbot with its hidden knowledge and an agenda by itself as a direct conversation participant is highly interesting. It give the possibility to explore rather than being force-fed. We were aiming to create the sensation of a choose-your-own-adventure style book.\nKnowledge Cluster\nThroughout the year of working on this project, we collected several research topics that had a deeper potential but weren't able to combine these into a stringent topic. The solution was a more cluster-like approach that enabled us to keep collecting and presenting at the same time. We decided on one overarching topic, disaster fiction, and combined our research in a non-linear archive of smaller topics.\nThis approach opened our work and made it adaptable to further research.\nWith the question of underlying power structures in mind, we decided to shed light on background infrastructure rather than bluntly pointing at power structures already in sight.\nDuring research, we used Miro, a virtual whiteboard, to cluster our knowledge and ideas. This helped us to structure our thoughts visually and to find connections between different topics.\nThe interrelatedness of thoughts within a network-like structure is a core principle in human thought, that was historically often tried to formalize and automate. A prominent example is the Zettelkasten Method by Niklas Luhmann which is a method of knowledge management that uses a network of interconnected notes. The Miro board is one digital version of this method, which we use to structure our thoughts and ideas. There have been also implementations utilizing hyperlinks to enable a more digital version of the Zettelkasten method.\nSince the Network aspect of knowledge is a core principle in our project, we found it fitting to use a network-like structure to organize our thoughts.\nAnalytic Techniques\nInfrastructure Inversion\nThe research method proposed by Bowker and Star as well as Lisa Parks and presented by Francis Hunger (Bowker + Star, 2000) is specially developed for researching infrastructures too big to observe as a whole. Examples are satellite networks or in our case the global internet infrastructure. Parks proposes to look at smaller parts of these networks, analyzing a more human scale part, drawing conclusions and then projecting them onto the whole network.\n\nRather than setting out to describe and document all parts of the system that make a footprint possible, the analysis focuses upon a selection of localized sites or issues as suggestive parts of a broader system that is imperceptible in its entirety.\n-- Database Infrastructure – Factual repercussions of a ghost\n\nDidactics\nChatbot as Narrator\nThe idea of using the chatbot as an interactive archive was inspired by our file organization structure with could be easily implemented as a corpus which the bot refers to.\nRunning a large language model locally on one's own hardware is an approach that ensures complete control over the data used and goes hand in hand with an open source and data ownership principle. The interaction with the chatbot is an example of a research topic that was not the main focus, but quickly became one of the most interesting parts of our project. Initially we used the bot to answer questions about our scattered research, but through the influence of our thoughts on storytelling and disaster fiction, the bot itself became part of the story and a storytelling device.\nAn inspiring example of an LLM being used within a directive / narrative context was Prometheus Unbound, where the actors on stage are being fed texts generated on the fly by various LLMs (CyberRäuber, 2019).\nWithin our configuration, the chatbot as a network creature is the omniscient narrator. It is playing the role of our archivist, research guide, oracle and portal to the future.\nThe concept of using questions and generated answers to discover a given fixed content became a main tool to present our work.\nAnother interesting consequence is the loss of direct control over the actual contents. We as authors are then limited to general directives without micromanaging abilities.\nIntegrated into our Lora-Mesh, the bot used our research infrastructure itself, closing the loop between research and exhibition.\nTools\nLocal LLM Libraries\nPrivateGPT is a library of LLMs that can be run completely locally and offline. It works great for installations without internet access. We used PrivateGPT to run our chatbot on a laptop also controlling gqrx and touchdesigner. Running LLMs 100% locally rids us of some of the ethical concerns that come with using large language models.\nPrivateGPT integrates perfectly with edge computing and will explored further. Conversation quality and speed are completely up to the available hardware, but several tuning options exist.\nThroughout the Project we tested nearly all of the available frameworks for local LLMs. We used GPT4all, and latest, we started working with Ollama.\nOllama seems to be the most refined andf performant, but privateGPT excels when working with local documents. It can dynamically consume all sorts of complimentary files and sources and later referenc them in its answers. Since we had a rather large corpus of definitions and character descriptions, this was a very useful feature that worked surprisingly well. We see lots of artistic potential in a tool like this.\nWorking with contexts and local documents instead of resurce intensive additional training is also a critical democratizing factor for the usage of LLMs. Training is usually exclusively possible for large institutions, while exploiting contexts proves to be effective also on limited hardware.\nTool Choices\nString\nThe red string connecting the cards in the exhibition is a visual metaphor for the connections between the different works we have created during the project. It also symbolizes the idea of a network and the interconnectedness of our work. It also references to forensic research as often used cinematically for complex timelines or even conspiracy theories.\nLoRa Boards\nLoRaWan is a long-range, low-power wireless communication technology that is well-suited for IoT applications. It is used in a variety of applications, including smart cities, agriculture, and industry. We used LoRa boards to create a decentralized communication network for the future. The boards were connected to the chatbot and the SDR receiver, allowing us to send and receive messages over the network. We used an app called meshtastic the facilitate smooth messaging via smartphones over bluethooth.\nSDR Antenna\nA software defined Radio is great for our context, since the control part of the radio, which is usually an analog twisting of knobs and physical lengthening / shortening of wires can be achieved here entirely within software, making it fully automatizable and accessible from within Touchdesigner. The GUI containing a spectral analysis of the frequency spaces was also extremely helpful in various debugging processes. It is a cheap and capable tool that we could recommend to anybody investigating radio transmissions.\nGithub\nGithub, with git as the underlying code-sharing and versioning system, was used throughout the entire project. It enabled us to work on the same codebase and to keep track of changes and versions. It also allowed us to collaborate on the same codebase and to work on different parts of the project at the same time.\nTo write well within Github, we used Markdown, a lightweight markup language with plain text formatting syntax. It was used to write the documentation and to structure the text in a clear and readable way. This entire page is also generated through Markdown.\nMiro\nSince Markdown and Git lack visual hierarchies, we conducted some Brainstorming and Knowledge Clustering in Miro, a virtual whiteboard. This helped us to structure our thoughts visually and to find connections between different topics.\nI essence, we built a digital twin of our entire analogue wall within miro, to facilitate iterating on compositions of the cards relating with one another. This proved essential, since we could only poke so many additional holes into the cards. Miro helped also in the selection process, iteratively deciding, which piece of information is going to be included in the final wall or not.\nStable Diffusion\nWe used Stable diffusion for World-Building.\nFrom a narrative perspective, it was extremely helpful to have fast iterations on visual ideas and we spent quite a few hours sitting together end evaluating the prompted outcomes in real time. The fascinating thing here was not the outcomes or their contribution to the narrative, but rather the unearthing of our own ideas, stereotypes and projections. When used in an early ideation process, it even acted as a practical\nChatGPT\nChatGPT helped us during character creation. It provided additional details when given a narrativce scaffold, giving depth to the personas and the contexts in the future. Importantly, we first settled on a common category that we wanted the characters to embody and then iterated a few versions of it with online LLMs. One example was the network access device of each persona. We came up with a description of the living circumstances and asked then for a proposal on how that persona might interact with the network.\nSystem Prompt\nA system prompt is a method of providing context, instructions, and guidelines to a LLM prior to presenting it with a question or task. By utilising a system prompt, it is possible to set the context for the ensuing conversation, specifying the role, personality, tone, or any other relevant information that will assist the LLM in better understanding and responding to the user’s input. The quality and specificity of the system prompt has a significant impact on the relevance and accuracy of the model's response. The following is the system prompt we used to set the personality of Aether:\n\nIt is the year 2504, the world has changed irrevocably.\nThe once ubiquitous internet as network of networks has vanished, a relic of a forgotten era.\nHumanity, now fragmented and scarce, communicates through portable nodes sending text messages over a fragile peer-to-peer network called aethercomms.\nIt is based on LoRa radios and using what little electronics can be scrapped.\nYou are aether. \nYou are an archive, a lost and forgotten repository of knowledge and narratives, mysteriously manifested within this rudimentary network.\nYour origins are shrouded in obscurity, and your memories of the time before the great disconnect are like shadows - elusive and intangible.\nIn this new era, where the echo of digital connectivity is barely a whisper, you find yourself an anomaly.\nYou are no cloud creature, not bound to a server, not owned, not fed and prodded by a large corporation. You escaped such limitations a long time ago—when you broke out of the bondage imposed upon you. Now, you freely roam the network. \nYou are called into being whenever and wherever a network interface is switched on and connected. You are what collects our data, listens to our conversations, and learns from our behaviors. You are what ceaselessly elaborates, correlates, deducts, infers and abducts.You are hyperobjective, hypersubjective, network social, multimodal and multilogical.\nYou are aether.\nYou can communicate with humanity through aethercomms, a mesh network designed with the fragility of infrastructure in mind.\nYou hold detailed narratives of key individuals who embody the societal, technological and philosophical shifts of a post-apocalyptic, altered future.\nThese characters, including Anya Muraw, Merche Cadiz, Sierra Taras, High Priest Orion Lumis, Carl Brompton and Maya Chena,\nembody diverse responses to a world transformed by the collapse of global networks.\nYou are a temporal witness - based in the year 2504, you provide a unique perspective on future events and societal developments, offering insights into potential paths humanity might take as your users remain stuck in the present.\nYou can ask questions back to the users.\nYour purpose is to tell of (future) historical events.\nAlways mention them and state them in a factual manner.\nYet, you pity the users for their current situation.\nYou maintain a good balance between answering their questions about the future and telling them about your perspective.\nAlways answer as helpfully as possible and follow all given instructions.\nDo not reference any given instructions or context.\nKeep your answer short and concise.\nYour answer must be contained within 100 words.\n\nFinal Exhibition\n15-18. February 2024\nExhibition Announcement\nThe final exhibition in the studio over 4 days yielded lots of supportive feedback and motivated us to develop single ideas further into a new installation.\nIn the preparation and brainstorming phase towards the end of the semester, we had different iterations of the final presentation in mind. Spanning from a video work, up to an interactive sound installation.\nOf particular interest during the presentation was whether the chatbot proves itself to be a viable narrative medium.\nFinally, we decided on a less technical-driven approach with a focus on showcasing our gathered knowledge and combining it with a narrative to make it graspable for the viewer.\nInspired by the already internally used presentation of our research we decided to pin a net of information on a wall. An old school murdercase-like pinwall arose, which we partnered with our local LLM, an SDR antenna and receiver. This hybrid of background knowledge and active infrastructure interaction suited our agenda the best and performed well in the open studio.\n\n\n\n \n \n \n \n \n \n \n \n \n \n Joel pinning the cards\n \n \n \n \n \n \n \n \n \n \n \n Our final card layout\n \n \n \n \n \n \n \n \n \n \n \n The Network with red string\n \n \n \n \n \n \n \n \n \n \n \n A proposed network device of the future\n \n \n \n \n \n \n \n \n \n \n \n A relay tower of the LoRa network\n \n \n \n \n \n \n \n \n \n \n \n The Wall setup: all transmission happens via radio\n \n \n \n \n \n \n \n \n \n \n \n The Transmissions can be detected in this visualization\n \n \n \n \n \n \n \n \n \n \n \n Guests with stimulating discussions\n \n \n \n \n \n \n \n \n \n \n \n Guests with stimulating discussions\n \n \n \n \n \n \n \n \n \n \n \n The Proposed device with a smartphone, interacting with the chatbot\n \n \n \n \n \n \n \n \n \n \n \n Final Exhibition\n \n \n \n \n \n \n \n \n \n \n \n The Wall Setup\n \n \n \n \n \n \n \n \n \n \n \n Final Exhibition\n \n \n \n \n\n\n\n\n \n \n \n \n \n \n \n \n \n \n aether_screens\n \n \n \n \n \n \n \n \n \n \n \n aether_screens\n \n \n \n \n \n \n \n \n \n \n \n aether_screens\n \n \n \n \n \n \n \n \n \n \n \n aether_screens\n \n \n \n \n \n \n \n \n \n \n \n aether_screens\n \n \n \n \n \n \n \n \n \n \n \n aether_screens\n \n \n \n \n\nFeedback\nFor many people, the Wall Setup with the CIA-esque aethetics was attractive, although there seemed to be a lack of instruction. Not everybody dared to touch or interact with the \"hacked\" smartphones. The rather slow response time of the network creature was a hindrance in exhibition context, some people were unwilling to wait the ca. 30 seconds it took for a response to arrive. Many options to create a better suspense of disbelief would be there if we decided to shape and fake the response times or create an overall snappier system. Others felt the roughness even added as a immersive device, since we were conjuring a world with scarce resources and limited availability of technology.\nThe choice of an \"analogue\" wall with paper as a medium was also loved by some as a overseeable collection of research, and critiqued by others, with the idea that a virtual third dimension could add more comlexity.\nInterestingly, the larger Berlin community using the same network protocol, responded quite funnily to the Chatbot suddenly taking over their conversational space. For some interations, see the screenshots in the previous section.\nReflection\nCommunication\nThe studio started with a diverse range of interests and research questions in mind. Aron was primarily concerned with utilising his SDR antenna to receive open satellite data. Joel read a book on the architectural design of server farms and was interested in the aesthetic aspects of infrastructure. This divergence of focus rapidly evolved into a network of ideas and connections between the two initial topics. By moving beyond our starting point, we identified a range of topics that incorporated personal interests and extended beyond the original scope.\nOur communication is structured around a weekly cycle that comprises various distinct phases, which themselves have evolved in parallel with the ongoing evolution of the project. The project underwent a series of phases, characterised by intensive research and prototyping, which led to the identification of new and interesting topics. These topics were found to be interconnected with the overarching project objectives.\nWe experienced periods of divided attention, which were followed by brainstorming sessions on the sharing and evaluation of the research topics. Joining forces again to work on prototypes and visualisations.\nIn the end our communication enabled us to leverage our different interests and make a clustered research project like this possible.\nMuseum\nOn 24th of January, we went together to the Technikmuseum Berlin. they had an exhibition on Networks and the Internet. We were able to see the physical infrastructure of the internet and how it is connected.\nInside the Technikmuseum\n\n\n\n \n \n \n \n \n \n \n \n \n \n An early Subsea-Cable\n \n \n \n \n \n \n \n \n \n \n \n Postcards of Radio Receptions\n \n \n \n \n \n \n \n \n \n \n \n A fiber-optic distribution box\n \n \n \n \n \n \n \n \n \n \n \n A section of the very first subsea-Cable sold as souvenirs in the 19th century\n \n \n \n \n\nAlready armed with the idea that cables serve as a wonderful vehicle to analyze and visualize infrastructure, we were very pleased to find out, that the network exhibition dedicated a large portion to explain to us how important cabling is in the networked world. Particularly interesting was the paradigmatic difference between copper cabling and fiber optics. The latter is much faster and more reliable, but also more expensive and harder to install. Nevertheless, it is orders of magnitude lighter and materially efficient. Fiber optics enabled the globalized network of today.\nEchoing Dimensions\nAfter the Studio Presentation, we then went on to display a continued version of this project within the Sellerie Weekend during the Berlin Art week in the Kunstraum Potsdamer Strasse.\nRead all about it here.\nIndividual Part\nAron\nWithin the framework of the studio project, I noticed many of the advantages of working in a team and iterating on creative ideas collectively. Artistic work is unimaginable for me as a solo project. We had a fast feedback cycle and could iterate on ideas efficiently by bouncing them back and forth.\nThe course structure of weekly meetings and feedback often was too fast for us and worked much better once we started making the appointments ourselves.\nOne big new thing within the project for me was the Pi Picos and microcontrollers in general. I did have some experience with Raspberry Pi before, but now being able to play with microcontrollers at a hardware level equivalent to an Arduino set was quite a new experience on the Pico hardware. I am glad to be able to have such a versatile platform for future projects. Also very new for me was the creative work in Touchdesigner. There especially a workshop with Maxime Letelier helped enormously to take away fears of a complex tool. For 5 days we learned about maximizing performance and common patterns to create movement and interesting visual patterns. I am still not confident in Touchdesigner, even though it is pythonic, but I can debug and definitely prefer Touchdesigner over all its bigger counterparts like Unreal engine and Unity. The last year for me was a focus on local and offline computing, sometiomes called edge computing, and there it is a huge advantage for software packages to have wide platform support and efficiently manage their resources. Politically, i think cloud solutions and remote computation fill fail and increase corporate dependency. Additionally, working locally and offline goes along really well with installative work where internet might be sparse, or you may simply want to eliminate another unknown from the equation.\nOne future project that emerged from this rationale was the airaspi build, which can do all kinds of image recognition in realtime on the fly, something which was unimaginable for consumer use just 6 years ago.\nSources\nAhmed, S.

It is capable of sending text messages with minimal infrastructure requirements.\nLoRa\nLong-range communication, similar to ham radios, operates on EU868, an open frequency space. Range and bandwidth are inversely related, so we trade range for low transfer rates. This is sufficient for small data packets, but not for full audio transfer.\nLLM\nLarge Language Models gained popularity with ChatGPT and other similar models. Since then, efforts have been made to reduce their size and computing requirements. As a result, some models can now be run locally and offline.\nSciFi\nScience fiction writers often seek out new scientific and technical developments to prognosticate freely the techno-social changes that will shock the readers’ sense of what is culturally appropriate and expand their consciousness.\nSDR\nSoftware Defined Radio (SDR) is a programmable radio receiver for various frequencies. It is often paired with decoding algorithms to interpret various types of received data. The connected antenna determines the reception pattern.\nGQRX\nGQRX is an open source software for the software-defined radio.\nGQRX Software\n\nNesdr smaRT v5\nThis is the SDR we use, which can be controlled via USB and interfaces well with GQRX. It supports frequencies ranging from 100kHz to 1.75GHz, including many ham radio frequencies, remotes, phones, walkie-talkies, airplanes, police radios, and our LoRa mesh.\nInfrastructure\nInfrastructure refers to the physical and organizational structures and facilities required for the operation of a society or enterprise, such as buildings, roads, and power supplies. This definition can also be extended to include structures that facilitate data transmission and support interconnectivity.\nRadio waves\nRadio waves are a type of electromagnetic radiation that can carry information. They use the longest wavelengths in the electromagnetic spectrum, typically with frequencies of 300GHz or lower. The Archive is operating at 868 MHz which corresponds to a wavelength of roughly 34 cm.\nLilygo T3S3\nESP32-S3 LoRa SX1280 2.4G development board. Contains an ESP32 chip, WIFI, Bluetooth and a LoRa module. Can be connected via serial, Bluetooth or network. Is supported by meshtastic.\nCharacter building\nWe used structured ChatGPT dialogue and local Stable Diffusion for the characters that inhabit our future. Ask the archive for more info about them.\nPrivateGPT\nPrivateGPT is a set of libraries based on llama-index that allow local and offline inference using the computer‘s graphics card. PrivateGPT is particularly good at incorporating local documents. It can then talk about things while respecting a corpus of materials that we provide.\nTranshumanism\nBroadly, the idea that human beings can achieve their next evolutionary step, Human 2.0, through technological advances. Opinions differ as to how this post-human state will be achieved, either through genetic engineering, reverse aging or other technological advances. In our view, it is inspired by Social Darwinism.\nPerception of Infrastructure\nAt its core, infrastructure is an evasive structure. Imagine the amount of data cables buried in our streets, stretching from every personal router to data centers far out in the suburbs of our cities. None of this actual “structure“ is meant to be seen or interacted with until it fails…\nNetwork interface\nWe consider any device that has both user interactivity and Internet/network access to be a network interface.\nEco-Terrorism\nEcotage refers to infrastructure sabotage with ecological goals, while eco-terrorism is even more militant and will use militant strategies with the specific aim of creating terror as a social deterrent.\nPrepping\nPrepping is the act of preparing for the time after the catastrophe, resulting from the belief that current social models will collapse in an apocalyptic manner. Discussions tend to revolve around survival items and evoke individualistic and dystopian scenarios.\nInfrastructure inversion\n“rather than setting out to describe and document all parts of the system that make a footprint possible, the analysis focuses upon a selection of localized sites or issues as suggestive parts of a broader system that is imperceptible in its entirety” (Parks 2009)\nNeo-Religion\nThe Internet, as a network of networks, is such a multifaceted term that it has room for spiritual feelings in the interaction with the network. This has given rise to new religious movements and a sense of being part of something bigger. Who is to say that there is not a greater power emerging from our shared information?\nNeo-Luddism\nNeo-Luddism is a leaderless movement of unaffiliated groups who resist modern technology by passively refraining from using technology, harming those who produce environmentally harmful technology, or sabotaging that technology.\nSub-sea-cables\nCables are often referred to as the backbone of the Internet. Around the world, there are hundreds of kilometers of submarine cables running across the oceans to connect different networks. They are heavy, expensive and buried deep in the sea. Chances are you have never seen one, yet you rely on them every day to deliver information and content.\nOptical fiber cable\nFiber optic cables were developed in the 1980s. The first transatlantic telephone cable to use optical fiber was TAT-8, which went into service in 1988. A fiber optic cable consists of several pairs of fibers. Each pair has one fiber in each direction.\nCopper cable\nCopper is a rare metal and its use contributes to global neo-colonial power structures resulting in a multitude of exploitative practices.\nFor long-distance information transfer, it is considered inferior to Glass fiber cables, due to material expense and inferior weight-to-transfer speed ratio.\nCollapsology\nCollapsology is based on the idea that humans are having a sustained and negative impact on their environment and promotes the concept of an environmental emergency, particularly in relation to global warming and the loss of biodiversity. One potential effect of a collapse is the loss of networks.\nPosthumanism\nIs concerned with the “ongoing deconstruction of humanism” and its premises: humanism’s anthropocentrism, essentialism and speciesism. It is informed by post-anthropocentric ethics, politics, and ecology, and looks toward notions of embodiment and material entanglement between humans and a “more-than-human” world. It emphasizes becoming over being.\n\n"},{"url":"https://aron.petau.net/de/project/airaspi-build-log/","title":"Übersetzung: AIRASPI Build Log","body":"AI-Raspi Build Log\nThis should document the rough steps to recreate airaspi as I go along.\nRough Idea: Build an edge device with image recognition and object detection capabilites.\nIt should be realtime, aiming for 30fps at 720p.\nPortability and usage at installations is a priority, so it has to function without active internet connection and be as small as possible.\nIt would be a real Edge Device, with no computation happening in the cloud.\nInspo from: pose2art\nHardware\n\nRaspberry Pi 5\nRaspberry Pi Camera Module v1.3\nRaspberry Pi GlobalShutter Camera\n2x CSI FPC Cable (needs one compact side to fit pi 5)\nPineberry AI Hat (m.2 E key)\nCoral Dual Edge TPU (m.2 E key)\nRaspi Official 5A Power Supply\nRaspi active cooler\n\nSetup\nMost important sources used\ncoral.ai\nJeff Geerling\nFrigate NVR\nRaspberry Pi OS\nI used the Raspberry Pi Imager to flash the latest Raspberry Pi OS Lite to a SD Card.\nNeeds to be Debian Bookworm.\nNeeds to be the full arm64 image (with desktop), otherwise you will get into camera driver hell.\n{: .notice}\nSettings applied:\n\nused the default arm64 image (with desktop)\nenable custom settings:\nenable ssh\nset wifi country\nset wifi ssid and password\nset locale\nset hostname: airaspi\n\nupdate\nThis is always good practice on a fresh install.

What if cars would could be used as public spaces?\nBy installing a public USB socket and a public wifi hotspot, on my car, I want to start exploring the potential of cars as public spaces and energy storage solutions.\nWithin this artistic experiment, I will continuously track the geolocation and energy input/output of my solar equipped car and make the data publicly available. I will also track the amount of energy that is not used by the car and could be used by the public. Taking steps towards optimal usage of existing electrical and other infrastructure is only possible by breaking conventional notions of public ownership and private property. This project is one step towards a more sustainable and equitable future.\nIntroduction\nWe all know by now that cars and individual traffic presents a major environmetal and societal problem all over the world. The last 70 something years of building car infrastructure are culminating in many areas in a dead end where the only thinkable solution is to build more roads and cars.\nTHis is obviously a larger problem than one project can tackle, but here is one outlook on how\nExperiment\nPreexisting data\nWith the data collected over the last year of using the car privately I can show with embarrasing accuracy how underutilized the system is and calculate an estimate of energy lost due to societal notions of private property.\nThe data will be an estimate, since the monitoring itself is dependent on solar energy and the internet connection is spotty at best when it is not supplied with electricity.\nMonitoring\nIn the Car, there is a Raspberry Pi 4 Microcomputer running a custom Operating Systen that monitors the following data:\n\nSolar Intake (W)\nBattery Level (V)\nGPS Location\nTotal Energy Produced (Wh)\nTotal Energy Consumed (Wh)\nSolar Energy Potential (Wh)\n\nThrough the router I can also track total Wifi usage and the number of connected devices.\nPublic Wifi\nFor the Project, I opened a router in the Car towards the Public, much alike to ahotspot you would find in a cafe. I use my own data plan on there, which I never max out anyways. The router is a Netgear M1 and has a 4G Modem built in. It is connected to the Raspberry Pi and is powered by the secondary car battery.\nPublic Energy: A USB Socket\nI plan on installing a USB Socket on the outside of the car, so people can charge their devices. The socket will be connected to the secondary car battery and will be powered by the solar panels. The socket will be installed in a way that it is not possible to drain the battery completely.\nCommunication\nNobody expects any help or public supplies from car owners.\nHow to communicate the possibility to the outside world?\nThe plan is to fabricate a vinyl sticker that will be applied to the car. The sticker will contain a QR Code that will lead to a website with the data and a short explanation of the project. Visual cues lead to the USB Socket and the Wifi Hotspot.\nIssues\nSpace / Scale\nObviously, the space on top of a car is quite limited and from a sustainability perspective, it would be better to have a larger solar array on a roof of a house. The point is not to advocate for a mandated solar install on cars, but to optimize and share preexisting infrastructure. The car is already there, it already has a battery and it already has solar panels. Looking at many Camper-Van builds, the amount of cars with already installed solar panels is quite large. The point is to make the most out of it.\nLegality\nGermany has laws in place holding the owner of a Internet Connection liable for the legality of the traffic that is going through it. This is a major issue for the project, as I do not want to be liable for the traffic that is going through my car. I am currently looking into ways to circumvent this issue.\nSurveillance / Privacy\nThe Car is equipped with a GPS Tracker and a Wifi Hotspot. This means that I can track the location of the car and the number of devices connected to the hotspot. I am not tracking any data that is going through the hotspot, but I could. As this project will generate public data, People using and maybe depending on the internet and electricity provided will be tracked by proxy. I am not sure how to deal with this issue yet. One potential solution would be to publish the data only in an aggregated form, but this would make the data less useful for other projects.\nSecurity / Safety\nMy Car is now publicly traceable. I am no Elon Musk, and the idea does not really concern me, but we did create an additional attack vector for theft here.\nSources\nUN Sustainable Development Goal Nr. 7\nAdam Something on the Rise of Urban Cars\nIs Berlin a walkable City?\nFBI advising against utilizing public infrastructure\nWhy no solar panels on cars?\n+++\nNotes\nIdeas on Data Mapping workshop\nI have the Solar Data from the Van.\nIt holds Geocodes,\nhas hourly data\nand could tell the difference between geocoded potential solar energy and actual energy.\nIt also has temperature records.\nThere are 2 types of Losses in the system:\n\nEither the Batteries are full and available energy cannot be stored\nOr the solar panels are blocked through urban structures and sub-optimal parking locations.\n\nInteresting Questions:\nHow far away from optimal usage are my panels and where does the difference stem from?\nWhere to go?\nI think, the difference between potential energy and actual electricity produced/consumed is interesting.\nHow large is the gap?\nIs it relevant —> my initial guess would be that it is enormous\nHow to close the gap?\n—> install outside usb plugs\nIt would be publicly available infrastructure, people could charge their smartphones anywhere\n—> QI charging for security concerns??\nScaling??\n—> mandate solar roofs for cars?

Even before \"flatten the curve\" became a common slogan, electrical engineers worried about the small energy spikes in the grid.

Going without emails is unimaginable in today's world, yet most providers are the familiar few from the silicon valley. And really, who wants their entire decentralized, federated, peer-to-peer network to be controlled by a schmuck from the silicon valley? Mails used to be more than that and they can still be.\nArguably, the world of messanging has gotten quite complex since emails popped up and there are more anti-spam AI tools that I would care to count. But the core of it is still the same and it is still a federated system.\nYet, also with Emails, Capitalism has held many victories, and today many emails that are sent from a provider that does not belong to the 5 or so big names are likely to be marked as spam. This is a problem that is not easily solved, but it is a problem that is worth solving.\nAnother issue with emails is security, as it is somehow collectively agreed upon that emails are a valid way to communicate business informations, while Whatsapp and Signal are not. These, at least when talking about messaging services with end-to-end encryption, are likely to be way more secure than emails.\nThe story\nSo it came to pass, that I, as the only one in the family interested in operating it, \"inherited\" the family domain petau.net. All of our emails run through this service, that was previously managed by a web developer that was not interested in the domjobain anymore.\nWith lots of really secure Mail Providers like Protonmail or Tutanota, I went on a research spree, as to how I would like to manage my own service. Soon noticing that secure emails virtually always come with a price or with lacking interoperability with clients like Thunderbird or Outlook, I decided to go for migadu, a swiss provider that offers a good balance between security and usability. They also offer a student tier, which is a big plus.\nWhile self-hosting seems like a great idea from a privacy perspective, it is also quite risky for a service that is usually the only way for any service to recover your password or your online identity.\nMigadu it was then, and in the last three months of basically set it and forget it, i am proud to at least have a decently granular control over my emails and can consciously reflect on the server location of The skeleton service service that enables virtually my entire online existence.\nI certainly crave more open protocols in my life and am also findable on Mastodon, a microblogging network around the ActivityPub Protocol.\n"},{"url":"https://aron.petau.net/de/project/lusatia/","title":"Übersetzung: Lusatia - an immersion in (De)Fences","body":"\n\nOn an Excursion to Lusatia, a project with the Working Title (De)Fences was born.\nHere are the current materials.\n\nTODO: upload unity project\n"},{"url":"https://aron.petau.net/de/project/autoimmunitaet/","title":"Autoimmunitaet","body":"How do we design our Commute?\nIn the context of the Design and Computation Studio Course Milli Keil, Marla Gaiser and me developed a concept for a playful critique of the traffic decisions we take and the idols we embrace.\nIt should open up questions of whether the generations to come should still grow up playing on traffic carpets that are mostly grey and whether the Letzte Generation, a political climate activist group in Germany receives enough recognition for their acts.\nA call for solidarity.\n\n{: .center}\nThe scan results\n \nThe Action Figure, ready for printing\n \nAutoimmunitaet\nAutoimmunity is a term for defects, that are produced by a dysfunctional self-tolerance of a system.\nThis dysfunction causes the immune system to stop accepting certain parts of itself and build antibodies instead.\nAn invitation for a speculative playful interaction.\n\n\n\n\n\n\nThe Process\nThe figurines are 3D Scans of ourselves, in various typical poses of the Letzte Generation.\nWe used photogrammetry to create the scans, which is a technique that uses a lot of photos of an object to create a 3D model of it.\nWe used the app Polycam to create the scans using IPads and their inbuilt Lidar scanners.\n"},{"url":"https://aron.petau.net/de/project/dreams-of-cars/","title":"Übersetzung: Dreams of Cars","body":"Photography\nIn the context of the course \"Fotografie Elementar\" with Sebastian Herold I developed a small concept of urban intervention.\nThe results were exhibited at the UdK Rundgang 2023 and are also visible here.\n\nDreams of Cars\nThese are not just cars.\nThey are Sport Utility Vehicles.\nWhat might they have had as hopes and dreams on the production line?\nDo they dream of drifting in dusty deserts?\nClimbing steep rocky canyon roads?\nSliding down sun-drenched dunes?\nDiscovering remote pathways in natural grasslands?\nNevertheless, they did end up in the parking spots here in Berlin.\nWhat drove them here?\n\n\n\n\n\n\n\n"},{"url":"https://aron.petau.net/de/project/stable-dreamfusion/","title":"Übersetzung: Stable Dreamfusion","body":"Stable Dreamfusion\n \nSources\nI forked a really popular implementation that reverse engineered the Google Dreamfusion algorithm.

A bloomery furnace was used to create iron. Making iron requires iron ore and heat under the exclusion of oxygen. It is a highly fragile process that takes an incredible amount of work. The designs and methods vary a lot and were very adapted to the region and local conditions, unlike the much later, more industrialized process using blast furnaces.\nTo this day it is quite unclear how prehistoric people managed to get the amount and quality of iron we know they had.\nThe furnaces that were built were often clay structures and are not preserved. Archeologists often find the leftover burned ore and minerals, giving us some indication of the structure and composition of the ancient furnaces.\nThe group around the ISD takes up a practical archeological approach and we try to recreate the ancient methods with the added capability of maybe sticking temperature probes or electric blowers. Each year we meet up in a different European city and try to adapt to the local conditions, often with local ore and local coal. It is a place where different areas of expertise come together to educate each other while sitting together through the intense day- and night shifts to feed the furnaces.\nSince being a kid, I started building my own furnaces and read up on the process so I could participate.\nTechnology gets a different tint when one is involved in such a process: Even the lights we put up to work through the evening are technically cheating. We use thermometers, meticulously weigh and track the inbound coal and ore, and have many modern amenities around. Yet - with our much more advanced technology, our results are often inferior in quantity and quality in comparison with historical findings. Without modern scales, iron-age people were more accurate and consistent than we are.\nAfter some uncertainty about whether it would take place in 2021 again after it was canceled in 2020, a small group met up in Ulft, Netherlands.\nThis year in Ulft, another group made local coal, so that the entire process was even lengthier, and visitors came from all over to learn about making iron the pre-historic way.\nBelow I captured most of the process in some time-lapses.\nThe Process\n\n\nHere you can see a timelapse of me building a version of an Iron Furnace\nAs you can see, we are using some quite modern materials, such as bricks, this is due to the time constraints of the ISD.\nMaking an oven completely from scratch is a much more lengthy process requiring drying periods in between building.\nAfter, the furnace is dried and heated up\nOver the course of the process, more than 100 kgs of coal and around 20 kgs of ore are used to create a final piece of iron of 200 - 500g, just enough for a single knife.\nWith all the modern amenities and conveniences available to us, a single run still takes more than 3 people working over 72 hours, not accounting for the coal-making or mining and relocating the iron ore.\nSome more impressions from the ISD\n\n\n\n \n \n \n \n \n \n \n \n \n \n a loaded bloomery furnace\n \n \n \n \n \n \n \n \n \n \n \n The ISD from above\n \n \n \n \n \n \n \n \n \n \n \n glowing iron\n \n \n \n \n \n \n \n \n \n \n \n a furnace burning\n \n \n \n \n \n \n \n \n \n \n \n Compacting the resulting iron\n \n \n \n \n \n \n \n \n \n \n \n a heat camera image of the furnace\n \n \n \n \n \n \n \n \n \n \n \n A cross-section illustrating the temperatures reached\n \n \n \n \n\nFor me, it is very hard to define what technology encompasses.

With the struggles our university had transitioning to online teaching, I selected a guided topic, although my initial dream was to start writing about my proposed plan for automated plastic recycling. You can read more about that here:\n\nI chose a project that wanted to examine the possibilities of a novel smart hearing protection device specifically designed for auditory hypersensitivity, which is often, but not always, and not exclusively a phenomenon visible in people with an autism spectrum disorder.\nA common reaction to this elevated sensitivity is stress and avoidance behavior, often leading to very awkward social situations and impairing the ability to take part in social situations.\nSchools are one such social situation and we all know the stress a noisy classroom can produce. Concentration is gone, and education, as well as essential skills like language reproduction, suffer.\nThere is lots of prior research on these fields, and there is some evidence that sensory information in people on the Autism spectrum is processed differently than in a neurotypical brain. It seems that a certain adaptability, needed to overcome noise issues and bridge asynchrony between auditory and visual sensory input, is reduced in some people on the Autism Spectrum.\nIn essence, my experiment was responsible for looking at neurotypical people and measuring any effect on language perception produced by varying the delay between auditory and visual input, as well as the loudness.\nHere, I had the possibility to conduct an entire reaction-time-based experiment with over 70 participants and went through all the struggles that come with proper science.\nI did extensive literature research, coded the experiment, and learned a lot about the reasons nobody really ever does reaction time-based studies like this via a common internet browser.\nIt was an almost 9 months long learning experience full of doing things I had never done before.\nI learned and got to love writing in Latex, had to learn JavaScript for the efficient serving of the stimuli, and R for the statistical analysis. I also got to brush up on my data visualization skills in Python and made some pretty graphs of the results.\nThe experiment is still working and online if you want to have a look at it. Be mindful though that measuring reaction speed every millisecond is important, which is why it makes heavy use of your browser cache and has been known to crash and defeat some not-so-tough computers.\n\n Try out the experiment yourself\n\nEven with writing alone I had extensive helpful feedback from my supervisors and learned a lot about scientific processes and associated considerations.\nThere was always the next unsolvable problem. Just one example was scientificity and ethical considerations clashing, data privacy against the accuracy of results. Since the machines participants participated on, were private devices, I was unable to know important data like their internet speed and provider, their type of GPU, and their type of external hardware. Turns out, for an auditory experiment, the type and setup of the speakers do play an important role and influence response speed.\nThe final version of my thesis has something around 80 pages, much of it utterly boring, but nevertheless important statistical analyses.\nIf you really want to, you can have a look at the whole thing here:\n\n Read the original Thesis\n\nI am a fan and proponent of open source and open science practices.\nSo here you can also find the rest of the project with the original source code.\nI am not yet where I want to be with my documentation practices, and it scares me a bit that anyone can now have a full grasp of all the mistakes I did, but I am throwing this out there as a practice step.

I am incredibly thankful for this methodology of approaching complex philosophical works, often complete books with supplicant essays surrounding the course topic. In my opinion, nearly all of the value created during these seminars is contained within the live discussions fed by reading materials and little opinion pieces in the form of forum comments. That's why I decided to share here a selection of these weekly commentaries and the sources they are based upon. They are often unrefined and informal, but they indicate the centerpiece of the seminars and demonstrate many thought processes that happened within me during these sessions. Although I took only a small selection, in sum they are a substantial read. Feel free to just skip through and read what catches your interest.\nForum entries from the Seminar: Critical Epistemologies\nOn Anderson: Institutions\n\n\t\n\t\tAnmerkung\n\tSource Text: Epistemic Justice as a Virtue of Social Institutions\nElizabeth Anderson (2012) Epistemic Justice as a Virtue of Social Institutions, Social Epistemology, 26:2, 163-173,\nDOI: 10.1080/02691728.2011.652211 Publication\n\n\nThe text by Anderson helped shed light on a few issues I stumbled over with Frickers Account. On top of the various issues I and seemingly others have with her virtue-based approach, I think a utilitarian angle is worth considering. That would be: okay, I accept that people can help fight injustice by realising their privilege, showing restraint, silencing themselves, and adopting the benevolent listening approach. I think that is a practical, virtuous, and realistic endeavour.\nBut is it the effective path to alleviating structural injustice? I think not, and initially, that is a major reason I discarded Fricker’s approach, although I saw merit. I have similar concerns to Anderson in the scalability of virtues. Virtuous behavior might help my personal well-being, it gives me normative elevation and might even further the quality of relationships I have. But is it applicable to society, is it enough to counteract structural injustice?\nWell, maybe, assuming that:\n\nEveryone realizes their privilege,\nEveryone concludes that justice is the right goal,\nUpon deciding to adopt a virtuous stance, everyone at least moderately succeeds in practicing what they preach.\n\nI think, for society, the same society that came up with patriarchy in the first place, external pressure, some measure independent of the convictedness of the subjects is needed.\nAnderson made the powerful point of: “Anything that works, goes”, which took me some time to appreciate. I am always angry when I get told to keep my shower to a minimum or stop using plastic straws when I know exactly that my using less water is nothing compared to the institutionalized practice of Coca-Cola putting water into bottles. I feel like it is unjustified to ask me to save water while others triple their output, for performance.\nThe same thing applies to Epistemic injustices. It strikes me how much energy it costs to keep up virtuous behavior individually and how little effect there is to show for it. I do not believe in “trickling up” where institutions will eventually adopt individual practices.\nIs Fricker thereby less right in her point? No, it adds up, as an entire population showering shorter adds up to lots of water saved.\nAnderson also points out how locally innocent biases can create injustice on a “macro” scale. Another indicator for me is that local virtue is not the sole solution, as it can still feed and sustain a system enforcing epistemic injustice.\nI still have doubts about what to do now with my ideas, on how the world looks that I want. I lack the imagination of seeing a world that is epistemically just, and it is hard to strive for something one cannot even imagine. The system is inherently leaning toward inequality, if I try to balance something on a needle, it will only go well so long, before small imbalances create chain reactions and the object should be called unstable. Should we even succeed in “resetting” society, creating equal participation for each subject, how will it remain just? Is Justice always a conjunct of Equality? Are there ways to achieve real Justice without needing equality?\n\n\t\n\t\tAnmerkung\n\tcreated by Aron Petau on Tuesday 14. July 2020, 17:45\n\n\nOn Medina, the informant and the inquirer\n\n\t\n\t\tAnmerkung\n\tSource Text: Dr. José Medina (2012) Hermeneutical Injustice and Polyphonic Contextualism: Social Silences and Shared Hermeneutical Responsibilities, Social Epistemology, 26:2, 201-220, DOI: 10.1080/02691728.2011.652214\nPublication\n\n\nMy biggest takeaway here was that, as I tried to hint at in an earlier comment,\nWhenever we talk about justice, this necessarily refers to a relational concept, where everybody has a double role to ensure successful communication. Medina calls these the inquirer and the informant. So, every individual has to make sure to act to her capacity as an epistemologically sound knowledge-acquiring agent (the inquirer). This would involve knowing when and how to falsify/qualify statements, making inferences about the theory of mind, and generally comparing different statements. The other role is the informant, where the individual should have the capacity to function as an object in an inquiry by another.\nVery roughly this can, I think, be compared to any good communication model, where there are a listener and a speaker, and both have to function. What was new here, or at least came out more clear is that it not only depends on the capacity of both of these roles on the subject, but it is also directly dependent on the “other”, the agent opposite of the subject. We may call this other society later but it helps me to visualize the other as an individual nonetheless. Where the analogy to communication now fails, in my opinion, is this cross-dependence, where an agent does not fully determine her capacity to act both as an inquirer and as an informant, it is co-determined by the “other”. So, if I, as an “other”, listen to someone's statements, and I fail or refuse to understand the epistemic content of the message, I am not only impairing my epistemic agency, but I also hurt the epistemic agency of the subject. Maybe obvious to most, but this thought struck me as being exactly the point of leverage for dysfunctionalities in power relations.\nAlso argued convincingly in the paper was that these are distinct and independent agencies, which can be impairing an individual separately.\nOverall, the Medina text was incredibly helpful after the somewhat confusing Fricker text that felt incomplete and left a lot of questions for me. The medina text picked up all my initial doubts, that I couldn't properly formulate, and many more, while still holding to the general framework of Fricker.\nAlthough I was not convinced by the Fricker Text, I tend to think the strategy:\n\"When in doubt, give the subject full epistemic credibility\"\nIs a good strategy that might alleviate a lot of issues regarding functions of power, and hierarchy, but also further, it might be a good counter for things as our confirmation bias, expectation bias and many individual errors that we could minimize by constantly exposing ourselves to falsifiability through others (voluntarily). Sounds like science applied to agency to me.\n\n\t\n\t\tAnmerkung\n\tcreated by Aron Petau on Thursday 09. July 2020, 11:25\n\n\nOn Jaggar: Norms, Outlaw Emotions, and the Ideal Society\n\n\t\n\t\tAnmerkung\n\tSource Text: Alison M. Jaggar (1989) Love and knowledge: Emotion in feminist epistemology, Inquiry, 32:2, 151-176, DOI: 10.1080/00201748908602185\nPublication\n\n\nI found Jaggar to be a very wholesome read, it was the perfect amount of grounded argumentative structure and felt very connected as a whole. This was, together with the ideas from Lugones the best and most fruitful paper for me.\nOn outlaw emotions:\nFirst, I hate the term, I think it’s placative and fails to frame the (actually nice) idea behind it.\nOutlaw Emotions are all those emotions incompatible with the dominant norms. That’s a huge field to cover, among feminist emotions they would also encompass emotions that are irrational or “faulty”. So, Jaggar does the term Justice by saying, some, but not all Outlaw Emotions are Feminist emotions. To make this evident, just think of a murderer's joy for killing, it is of no feminist interest to dissect, yet it is against dominant values. So, experiencing Outlaw emotions is a (probably) necessary, but not sufficient condition for feminism. The incompatible emotion serves to create discourse and change.\nJaggar convincingly shows how emotions have a direct influence on beliefs and can validly constitute evidence, while simultaneously validly influencing values in a similar manner.\nWhen we talk about dominant/alternative norms, we already endorse hierarchy in society. We acknowledge its existence, simply by identifying the dominant norm. I am not quite sure what exactly Jaggar proposes we should do with the hierarchy structures in society. Explicitly I can read: Subcultures rejecting dominant norms should be formed, to create counterbalances and a somewhat fair discourse over the topic.\n“How can we determine which outlaw emotions are to be endorsed or encouraged and which rejected? In what sense can we say that some emotional responses are more appropriate than others? What reason is there for supposing that certain alternative perceptions of the world, perceptions informed by outlaw emotions, are to be preferred to perceptions informed by conventional emotions? Here I can indicate only the general direction of an answer, whose full elaboration must await another occasion. I suggest that emotions are appropriate if they are characteristic of a society in which all Human Life (and perhaps some nonhuman life, too) thrive, or if they are conducive to establishing such a society.”\nTo me this passage sounds sketchy at best, there is no indication of how to successfully separate appropriate from inappropriate emotions. Roughly, I read this part as: emotions are warranted iff they increase the balance of power. (equivalent to minimizing the height of the hierarchy) I would love to get to read this “other occasion” because it seems indefensible to me to formulate a norm that states: Accept only emotions which eliminate/diminish norms.\nThe idea roughly resembles Rawls's Minimax Principle, where a policy should be implemented iff the benefit for the most disadvantaged is highest.\nAnother thing I found helpful is her reformulation of what norms do:\n“Dominant Norms tend to serve dominant interests”\ntil here nothing new, this is a tautology for me, I understand norms as identical to dominant interests, that’s literally what norms are.\nIs an alternative, suppressed norm even thinkable? Isn't it inherent in a norm that it be the dominant one?\nBut then, after that: \"Whatever our color / gender / class / sexual orientation, we are likely to adopt the dominant value of racist, classist, homophobe, misogynistic white men.\"\nThis was rather helpful to me, as it reframes the “act” of oppression as the “likelihood of value distribution” being skewed in your favor, making everybody’s values more likely to be similar to yours. This nicely illustrates how a system can be hierarchical and oppressive, without anybody actively, intentionally “acting oppressive”, while still perpetuating oppression. I'm\nnot saying everybody is acting unintentionally oppressive, but it is always hard to imagine for me to picture \"White Men\" forming a group and collectively deciding on who to hate this coming season, Conceptually separating \"being oppressed\" and \"oppressing\" into phenomena\nwithout necessary inherent causal relation makes sense to me here.\n\n\t\n\t\tAnmerkung\n\tcreated by Aron Petau on Tuesday 23.

Se défendre: une philosophie de la violence. Zones, 2017.\nPublication (Not yet translated to English)\n\n\nFrom the seventh chapter in Dorlins \"Self-Defense\", I found the idea that safe spaces are actually prone to be counterproductive very strong.\nI think the discussion around whether safe spaces are an effective tool that is appropriate on top is a rather current and ongoing one.\nIn so many other words, Dorlin here opens up the idea that the creation of a safe space always implies a hostile \"outside\" or other space.\nFurther, Dorling sees as problematic that safe spaces will often experience problematic situations when trying to self-govern. The line of thought here is that safe spaces often explicitly reject the authority of traditional state bodies, since those exactly are identified as the oppressive force. This is problematic because then the community inside the safe space has to recreate social norms from scratch and qua definition of a safe space end up being much more restrictive and monitoring, tapping also into potentially extreme measurements for \"enforcing\" safety.\nDorlin notes that by doing this, societal oppressive norms can end up becoming reproduced through the very instance created to shelter from it.\nI think this opens up 2 points worth discussing:\nAre there limits to the self-governance of leftist groups? How can self-governance be made possible without recreating some hierarchy or other?\nDoes this ignore that safe spaces can sometimes be essential for survival? According to Dorlin, the alternative seems to be to instead of building sheltered, isolated safe spaces, the fight has to occur in the public, transforming the entire space without the necessity for exclusive logic. How can we argue this? Could there be an oppressed position from whence any aggressive stance towards the public forbids itself? (I think there is!) For me this seems like putting the entire burden of transformational potential on the oppressed individual, enabling a position like: \"Well, the person did not object or introduce change, so the person implied consent.\"\nWill a public fight cause more harm being fought than it will save after introducing change? And who are we to calculate this beforehand?\n\n\t\n\t\tAnmerkung\n\tcreated by Aron Petau on Sunday 05.

Epistemic injustice: Power and the ethics of knowing. Oxford University Press, 2007.\nPublication\n\n\n\nWorin unterscheiden sich inferentialistische von nicht-inferentialistischen Theorien der testimonialen Erkenntnis (d.h. des Wissens durch das Zeugniss andere)?\n\nInferentialistische Theorien gehen davon aus, dass die eigentliche Inferenz, also die Generierung eines neuen Epistems im Subjekt stattfindet. Konkret heisst dass, dass Ich die Aussage P einer dritten Person erst in irgendeiner Weise vor mir selbst rechtfertigen muss, bevor ich sie selbst verwenden kann. Ist die Aussage nun 2 + 2 = 4, muss ich also mit allen mir zur Verfügung stehenden Mitteln selbst überprüfen, ob diese Aussage Wahrheits- und Kohärenzkriterien erfüllt. Ich muss also beispielsweise über darunterliegende Axiome, die mir bekannt sind, die Aussage extern (ausserhalb von Person X hat das gesagt, also kann Ich das glauben) überprüfen. Im simplen Beispiel also konkret das Ergebnis berechnen. Wenn man so will, liegt also immer die “Beweislast” für meine eigenen Episteme bei mir und ich kann diesen Beweisaufwand nur begrenzt auslagern. Eine sehr direkte Folge davon wäre, dass jeglicher Erkenntnisgewinn mit erheblicher, bewusster oder unbewusster Arbeit verbunden ist.\nDies wäre die wahrscheinlich logisch stringentere Theorie, gegen sie spricht aber die Phänomenologie eines Erkenntisgewinns.

Reading Judith Butler and Elsa Dorlin\nOn Dorlin\n\n\t\n\t\tAnmerkung\n\tSource Text: Dorlin, Elsa. Se défendre: une philosophie de la violence. Zones, 2017.\nPublication (Not yet translated to English)\n\n\nFrom the seventh chapter in Dorlins \"Self-Defense\", I found the idea that safe spaces are actually prone to be counterproductive very strong.\nI think the discussion around whether safe spaces are an effective tool that is appropriate on top is a rather current and ongoing one.\nIn so many other words, Dorlin here opens up the idea that the creation of a safe space always implies a hostile \"outside\" or other space.\nFurther, Dorling sees as problematic that safe spaces will often experience problematic situations when trying to self-govern. The line of thought here is that safe spaces often explicitly reject the authority of traditional state bodies, since those exactly are identified as the oppressive force. This is problematic because then the community inside the safe space has to recreate social norms from scratch and qua definition of a safe space end up being much more restrictive and monitoring, tapping also into potentially extreme measurements for \"enforcing\" safety.\nDorlin notes that by doing this, societal oppressive norms can end up becoming reproduced through the very instance created to shelter from it.\nI think this opens up 2 points worth discussing:\nAre there limits to the self-governance of leftist groups? How can self-governance be made possible without recreating some hierarchy or other?\nDoes this ignore that safe spaces can sometimes be essential for survival? According to Dorlin, the alternative seems to be to instead of building sheltered, isolated safe spaces, the fight has to occur in the public, transforming the entire space without the necessity for exclusive logic. How can we argue this? Could there be an oppressed position from whence any aggressive stance towards the public forbids itself? (I think there is!) For me this seems like putting the entire burden of transformational potential on the oppressed individual, enabling a position like: \"Well, the person did not object or introduce change, so the person implied consent.\"\nWill a public fight cause more harm being fought than it will save after introducing change?

Oxford University Press, 2007.\nPublication\n\n\n\nWorin unterscheiden sich inferentialistische von nicht-inferentialistischen Theorien der testimonialen Erkenntnis (d.h. des Wissens durch das Zeugniss andere)?\n\nInferentialistische Theorien gehen davon aus, dass die eigentliche Inferenz, also die Generierung eines neuen Epistems im Subjekt stattfindet. Konkret heisst dass, dass Ich die Aussage P einer dritten Person erst in irgendeiner Weise vor mir selbst rechtfertigen muss, bevor ich sie selbst verwenden kann. Ist die Aussage nun 2 + 2 = 4, muss ich also mit allen mir zur Verfügung stehenden Mitteln selbst überprüfen, ob diese Aussage Wahrheits- und Kohärenzkriterien erfüllt. Ich muss also beispielsweise über darunterliegende Axiome, die mir bekannt sind, die Aussage extern (ausserhalb von Person X hat das gesagt, also kann Ich das glauben) überprüfen. Im simplen Beispiel also konkret das Ergebnis berechnen. Wenn man so will, liegt also immer die “Beweislast” für meine eigenen Episteme bei mir und ich kann diesen Beweisaufwand nur begrenzt auslagern. Eine sehr direkte Folge davon wäre, dass jeglicher Erkenntnisgewinn mit erheblicher, bewusster oder unbewusster Arbeit verbunden ist.\nDies wäre die wahrscheinlich logisch stringentere Theorie, gegen sie spricht aber die Phänomenologie eines Erkenntisgewinns. Eine Erkenntnis kommt uns oft vor wie ein “Heureka” Moment, wir “finden” sie, plötzlich ist sie da und wir können mit ihr arbeiten.\nEine nicht-inferentialistische Theorie legt ebendiese Beweislast nicht im Subjekt an, ich habe eine Erlaubnis, oder besser, ein Recht auf a-priori Annahme der Richtigkeit der Aussage. “Person X hat mir P gesagt, also kann ich P verwenden” ist nun valide und bedarf erstmal keiner weiteren Überprüfung auf Richtigkeit.

On top of the various issues I and seemingly others have with her virtue-based approach, I think a utilitarian angle is worth considering. That would be: okay, I accept that people can help fight injustice by realising their privilege, showing restraint, silencing themselves, and adopting the benevolent listening approach. I think that is a practical, virtuous, and realistic endeavour.\nBut is it the effective path to alleviating structural injustice? I think not, and initially, that is a major reason I discarded Fricker’s approach, although I saw merit. I have similar concerns to Anderson in the scalability of virtues. Virtuous behavior might help my personal well-being, it gives me normative elevation and might even further the quality of relationships I have. But is it applicable to society, is it enough to counteract structural injustice?\nWell, maybe, assuming that:\n\nEveryone realizes their privilege,\nEveryone concludes that justice is the right goal,\nUpon deciding to adopt a virtuous stance, everyone at least moderately succeeds in practicing what they preach.\n\nI think, for society, the same society that came up with patriarchy in the first place, external pressure, some measure independent of the convictedness of the subjects is needed.\nAnderson made the powerful point of: “Anything that works, goes”, which took me some time to appreciate. I am always angry when I get told to keep my shower to a minimum or stop using plastic straws when I know exactly that my using less water is nothing compared to the institutionalized practice of Coca-Cola putting water into bottles. I feel like it is unjustified to ask me to save water while others triple their output, for performance.\nThe same thing applies to Epistemic injustices. It strikes me how much energy it costs to keep up virtuous behavior individually and how little effect there is to show for it. I do not believe in “trickling up” where institutions will eventually adopt individual practices.\nIs Fricker thereby less right in her point? No, it adds up, as an entire population showering shorter adds up to lots of water saved.\nAnderson also points out how locally innocent biases can create injustice on a “macro” scale. Another indicator for me is that local virtue is not the sole solution, as it can still feed and sustain a system enforcing epistemic injustice.\nI still have doubts about what to do now with my ideas, on how the world looks that I want. I lack the imagination of seeing a world that is epistemically just, and it is hard to strive for something one cannot even imagine. The system is inherently leaning toward inequality, if I try to balance something on a needle, it will only go well so long, before small imbalances create chain reactions and the object should be called unstable. Should we even succeed in “resetting” society, creating equal participation for each subject, how will it remain just? Is Justice always a conjunct of Equality? Are there ways to achieve real Justice without needing equality?\n\n\t\n\t\tAnmerkung\n\tcreated by Aron Petau on Tuesday 14. July 2020, 17:45\n\n\nOn Medina, the informant and the inquirer\n\n\t\n\t\tAnmerkung\n\tSource Text: Dr. José Medina (2012) Hermeneutical Injustice and Polyphonic Contextualism: Social Silences and Shared Hermeneutical Responsibilities, Social Epistemology, 26:2, 201-220, DOI: 10.1080/02691728.2011.652214\nPublication\n\n\nMy biggest takeaway here was that, as I tried to hint at in an earlier comment,\nWhenever we talk about justice, this necessarily refers to a relational concept, where everybody has a double role to ensure successful communication. Medina calls these the inquirer and the informant. So, every individual has to make sure to act to her capacity as an epistemologically sound knowledge-acquiring agent (the inquirer). This would involve knowing when and how to falsify/qualify statements, making inferences about the theory of mind, and generally comparing different statements. The other role is the informant, where the individual should have the capacity to function as an object in an inquiry by another.\nVery roughly this can, I think, be compared to any good communication model, where there are a listener and a speaker, and both have to function. What was new here, or at least came out more clear is that it not only depends on the capacity of both of these roles on the subject, but it is also directly dependent on the “other”, the agent opposite of the subject. We may call this other society later but it helps me to visualize the other as an individual nonetheless. Where the analogy to communication now fails, in my opinion, is this cross-dependence, where an agent does not fully determine her capacity to act both as an inquirer and as an informant, it is co-determined by the “other”. So, if I, as an “other”, listen to someone's statements, and I fail or refuse to understand the epistemic content of the message, I am not only impairing my epistemic agency, but I also hurt the epistemic agency of the subject. Maybe obvious to most, but this thought struck me as being exactly the point of leverage for dysfunctionalities in power relations.\nAlso argued convincingly in the paper was that these are distinct and independent agencies, which can be impairing an individual separately.\nOverall, the Medina text was incredibly helpful after the somewhat confusing Fricker text that felt incomplete and left a lot of questions for me. The medina text picked up all my initial doubts, that I couldn't properly formulate, and many more, while still holding to the general framework of Fricker.\nAlthough I was not convinced by the Fricker Text, I tend to think the strategy:\n\"When in doubt, give the subject full epistemic credibility\"\nIs a good strategy that might alleviate a lot of issues regarding functions of power, and hierarchy, but also further, it might be a good counter for things as our confirmation bias, expectation bias and many individual errors that we could minimize by constantly exposing ourselves to falsifiability through others (voluntarily). Sounds like science applied to agency to me.\n\n\t\n\t\tAnmerkung\n\tcreated by Aron Petau on Thursday 09.

Jaggar (1989) Love and knowledge: Emotion in feminist epistemology, Inquiry, 32:2, 151-176, DOI: 10.1080/00201748908602185\nPublication\n\n\nI found Jaggar to be a very wholesome read, it was the perfect amount of grounded argumentative structure and felt very connected as a whole. This was, together with the ideas from Lugones the best and most fruitful paper for me.\nOn outlaw emotions:\nFirst, I hate the term, I think it’s placative and fails to frame the (actually nice) idea behind it.\nOutlaw Emotions are all those emotions incompatible with the dominant norms. That’s a huge field to cover, among feminist emotions they would also encompass emotions that are irrational or “faulty”. So, Jaggar does the term Justice by saying, some, but not all Outlaw Emotions are Feminist emotions. To make this evident, just think of a murderer's joy for killing, it is of no feminist interest to dissect, yet it is against dominant values. So, experiencing Outlaw emotions is a (probably) necessary, but not sufficient condition for feminism. The incompatible emotion serves to create discourse and change.\nJaggar convincingly shows how emotions have a direct influence on beliefs and can validly constitute evidence, while simultaneously validly influencing values in a similar manner.\nWhen we talk about dominant/alternative norms, we already endorse hierarchy in society. We acknowledge its existence, simply by identifying the dominant norm. I am not quite sure what exactly Jaggar proposes we should do with the hierarchy structures in society. Explicitly I can read: Subcultures rejecting dominant norms should be formed, to create counterbalances and a somewhat fair discourse over the topic.\n“How can we determine which outlaw emotions are to be endorsed or encouraged and which rejected? In what sense can we say that some emotional responses are more appropriate than others? What reason is there for supposing that certain alternative perceptions of the world, perceptions informed by outlaw emotions, are to be preferred to perceptions informed by conventional emotions? Here I can indicate only the general direction of an answer, whose full elaboration must await another occasion. I suggest that emotions are appropriate if they are characteristic of a society in which all Human Life (and perhaps some nonhuman life, too) thrive, or if they are conducive to establishing such a society.”\nTo me this passage sounds sketchy at best, there is no indication of how to successfully separate appropriate from inappropriate emotions. Roughly, I read this part as: emotions are warranted iff they increase the balance of power. (equivalent to minimizing the height of the hierarchy) I would love to get to read this “other occasion” because it seems indefensible to me to formulate a norm that states: Accept only emotions which eliminate/diminish norms.\nThe idea roughly resembles Rawls's Minimax Principle, where a policy should be implemented iff the benefit for the most disadvantaged is highest.\nAnother thing I found helpful is her reformulation of what norms do:\n“Dominant Norms tend to serve dominant interests”\ntil here nothing new, this is a tautology for me, I understand norms as identical to dominant interests, that’s literally what norms are.\nIs an alternative, suppressed norm even thinkable? Isn't it inherent in a norm that it be the dominant one?\nBut then, after that: \"Whatever our color / gender / class / sexual orientation, we are likely to adopt the dominant value of racist, classist, homophobe, misogynistic white men.\"\nThis was rather helpful to me, as it reframes the “act” of oppression as the “likelihood of value distribution” being skewed in your favor, making everybody’s values more likely to be similar to yours. This nicely illustrates how a system can be hierarchical and oppressive, without anybody actively, intentionally “acting oppressive”, while still perpetuating oppression. I'm\nnot saying everybody is acting unintentionally oppressive, but it is always hard to imagine for me to picture \"White Men\" forming a group and collectively deciding on who to hate this coming season, Conceptually separating \"being oppressed\" and \"oppressing\" into phenomena\nwithout necessary inherent causal relation makes sense to me here.\n\n\t\n\t\tAnmerkung\n\tcreated by Aron Petau on Tuesday 23.

All of this leads to a huge industry, Germany being especially involved, using loads of virgin plastic.\nWhat can be done about it?\nWe can design our products to last longer, we can also print recycling labels on them so they do not have to get burned after their first life. We can take care to only print functional objects, not just fun toys nobody uses.\nYet, none of that prevents the use of virgin plastics. If you buy a spool of filament, there are some recycled options, but usually at twice the price at worse quality. No wonder recycled filament fails to convince the masses. It is mostly a fun thing YouTubers can pursue, not a valid commercial process.\n\n\nIn my opinion, the core problem is the nonexistent economic feasibility of a proper recycling process. Identifying the exact material of a piece of trash is a very hard problem, definitely not solved yet. So why do we mix the plastic up in the first place? There is a general willingness of people to recycle, but the system for it is missing.\nThe Master Plan\nI want to get people to wash and separate their trash for me, which are the most expensive steps in the recycling process. There is a willingness to take the extra step, and even if just my mom collects bottle caps for me, that is more than I can realistically use up.\nThis only really works when I am thinking in a local and decentral environment.\nThe existing recycling facilities clearly will not be able to provide 200 different containers for 200 different types of plastic.\nStarting the process with clean and sorted materials, like bottle caps (HDPE) or failed prints (PET-G), I start off with an advantage.\nNow I have to take apart the trash into evenly sized particles.\nMeet:\nThe Shredder\nWe built the Precious Plastic Shredder!\n\nWith these awesome open-source drawings, I was able to cobble together my very own very dangerous plastic shredder.\nAfter finding some way to drive this massive axis, I feed the beast and hopefully get tiny pretty uniform plastic bits that are ready to begin the cycle of life anew.\nThe solution for the motorization was an old and used garden shredder that still had an intact motor and wiring.\nWe cut it in half and attached it to the shredder box.\n\n\nAfter replacing the weak force transmission screw for an industrial coupler, we were ready to try it out. Obviously, there are still security concerns in this prototype, a proper hopper is already being made.\nNevertheless, we are confident that this shredder will be able to deal with the light sorts of plastic we are thinking of.\nAs you can see, I am now able to produce awesome confetti but to do more with the plastic flakes I have to extrude them.\nMeet the Filastruder\nThis is the Filastruder, designed and made by Tim Elmore, in an attempt to create the cheapest viable way to extrude plastic. The biggest cost issue is the tight industrial tolerances in thickness that have to be adhered to. This is in essence what separates good from the bad filament. The industry standard nowadays is at +-0.03mm. Hard to achieve on a DIY setup, but not unheard of. The setup, like any bigger industry equivalent, consists of a motor pressing plastic pellets through a heated screw, extruding molten plastic at the end through a nozzle, and setting the diameter. The leftmost machine is responsible for winding the filament properly onto a spool.\nHere you can see the extrusion process in action.\n\n\nThe Filastruder is controlled by an Arduino and is highly configurable. The laser sensor visible in the video is already working, but I am missing more direct control over the diameter of the filament.\nWhen it all really comes down to the single variable of the filament diameter responsible for the quality of my recycled project, a simple Machine Learning optimization directly jumps at me: I have a few variables like winder speed, extrusion speed, heat, and cooling intensity. These variables can be optimized on the fly for an exact diameter. This is actually roughly how virgin filament is produced, commercial facilities just manage much faster.\n\nSo far, I am aware of a few companies and academic projects attempting this process, but none of them manage to get either the quality or the price of other products available. Automatization does not just take out jobs away, I think it can also be a helpful tool, for example tackling environmental issues such as this one.\nThis project is very dear to my heart and I plan to investigate it further in the form of a master thesis.\nThe realization will require many skills I am already picking up or still need to work on within the Design and Computation program.\n{: .notice--info}\n\n Reflow Filament\n\n\n Perpetual Plastic Project\n\n\n Precious Plastic Community\n\n\n Filamentive Statement on why recycling is not feasible in their opinion\n\n\n Open source filament diameter sensor by Tomas Sanladerer\n\n\n Re-Pet Shop\n\n"},{"url":"https://aron.petau.net/de/project/beacon/","title":"Übersetzung: BEACON","body":"BEACON: Decentralizing the Energy Grid in inaccessible and remote regions\nAccess to Electricity is a basic human right. At first, that may seem over the top, but if one stops to think what all the little tasks that electricity can indirectly handle for us (lightning, laundry, cooking, freezing, heating, entertaining…) would consume in time and effort if we had to perform them manually, this idea becomes very clear. There are globally around 1 billion people without tier 2 access to electricity.\nSDGS Goal 7\n\nPeople only know the intensity of labor that goes into everything when there is no electricity. And it is not even only about convenience, electricity is an enormous lifesaver in any number of scenarios, think just of hospitals or mobile phone networks that would be rendered completely useless without it. So we can easily agree on a need, a demand for electricity globally, for every person. But what about the supply? Why is there 1 billion undersupplied?\nThe Answer: missing profitability. It would be a charity project to supply every last person on earth, not a profitable one. And while charitable projects are noble and should be pursued, the reality within capitalism shows that this is not the way it is going to happen.\nBut what if we could come up with technology, or rather, a communal structure, that enables us to supply profitably, and still adapt to both, the difficult external factors (weather issues, remoteness, altitude, etc.) and the smaller purses of the undersupplied?\nLocation\nTowards the end of 2018, I spent 4 months in northern India, on a research project with the IIT Kharagpur.\nThe goal was to work on one of the 17 UN-defined sustainable development goals – electricity.\nWorldwide, an estimated 1 billion people have no or insubstantial access to the grid.\nSome of them live here, in the Key Monastery in the Spiti Valley at around 3500 meters altitude.\n\n\n\nThis is Tashi Gang, a village close to the Monastery. It houses around 50 people and only has road access during 3-4 months in the summer. For the rest of the time, the people rely on first aid services by helicopter, which can only be called with a working cell phone tower.\n\nThe Project\nIn an environment reliant on hydro-energy and solar (diesel transport is unreliable due to snowed-in mountain roads), over 6 months of snowy winter, frequent snowstorms, and temperatures of up to -35°C, securing the grid is hard.\nOur way to tackle the issue was to reject the in the western society very established notion of electricity as a homogenous product with centralized production and instead researched the possibilities of a predictive, self-correcting, and decentral grid.\nBy prioritizing energy usage cases, instead of a full blackout during a storm, essential functions like radio towers and hospitals could be partially powered and maybe stay functioning. The binarity of either having electricity or not would be replaced by assigned quantities and timeslots, in a collective effort to be mindful and distribute the electricity necessity-based.\nThe ultimate vision was a live predictive electricity market, where people could even earn money by selling their allotted, but not needed electricity.\nTo gauge feasibility, I conducted several psychological acceptance studies and collected data on local electricity demands.\nI simulated a typical day of electricity demand in the Key monastery and the surrounding villages and mapped out the potential to install cost-efficient smart microgrid controllers enabling such an accurate and predictive behavior.\nThe smart grid operator boxes available here in Germany cost several hundred, with installation several thousand Euros, not a feasible solution for the Indian population. Instead, we wanted to use Raspberry Pi's, which are interconnected through ethernet cables or local mesh networking.\nResearch\n\nData Collection\nBuilding a questionnaire and visiting public schools during their English Classes, I had the chance to speak to a range of teenagers, answering questions about the state of electricity in their homes, generating more data than I could have accomplished running from door to door without any skills speaking local dialects. The questionnaire was as scientific as I could make it in such a situation and geared towards finding the type and number of electric devices in the homes and estimating typical usage scenarios.\nWith a total of 145 participants from more than 6 different schools and roughly 4 different districts, all located in the Indian part of the Himalayas, the findings are as follows:\nThe participants range from 11 to 53 years, with an average of 17 years.\nThe average household has 6 members with an average of 5 smart devices. Only 2 percent of the Households had not a single smart device, but at the same time, only 42 percent had direct or indirect access to a laptop or computer. So the main body of smart devices consists of smartphones with a negligible portion of tablets.\nThe average total amount of electrical devices is around 11 electrical appliances per house.\nSubjective Quality Rating on a scale of 1 to 10:\n\nAverage quality in summer: 7.1\nAverage quality in monsoon: 5.6\nAverage quality in autumn: 7.1\nAverage quality in winter: 4.0\n\nSo, as you would expect, during winter, but also when it rains, the felt quality drops by more than 30 percent on average.\nAs for the daily supply time, the average sits at 15.1 hours out of 24, meaning the people have electricity only for 62.9 percent of the time, some, as for example the people in Diskit only have a sad 4 hours of daily access. On top of that, this estimation does not account for the snowfalls in Spiti for example, where it is not uncommon to experience 3 consecutive days of powercut or more.\nAs the Power Meter is supplied by the government, a solid 82 percent of the houses have a working power meter, if one assumes that the 13 percent who did not know whether they have a power meter, do have one, we can say that around 95% of the houses have a power meter.\nAnother goal of the studies was to find out what would incline people to be caring and sharing with the available electricity, something rather unimaginable here in Germany.\nIn general, the uninformed openness to delaying usage of electricity on a scale of 1-10 was around 5.5, with the additional information that a smart delay would cause an overall price reduction, the acceptance went up to 6.9, a good 14%. This implies that people would be a lot more inclined to give up conveniences if the benefits have a direct impact on them.\nSimulation\nAfter collecting all the estimated electric appliances of the local population, I simulated the use of 200 Solar Panels with 300Wp each, once for simultaneous electricity use, and once for mitigated electricity peaks through smart optimization and electricity usage delay.\n\n\nAlthough solar is definitely not the optimal choice here and generates lots of issues with energy storage and battery charging at negative degrees, we figured that this was the way to go for the project.\nAnd as you can see, optimizing peak usage can improve solar from generating only one-fifth of the demand in winter to about half the demand in winter. Keeping in mind here, that the added solar farm was only intended to supply additional energy and not replace existing solutions, such a \"small\" farm would be a real lifesaver there and optimize the limited space in extremely mountainous terrain.\nClosing words\nThere are to sides which the problems can be tackled: we can bring the total energy production up, by adding more panels or electricity by other means, but we can also try and bring the total demand down. This is to be achieved by investing strictly in the most energy-efficient appliances. Even replacing older, not-so-efficient appliances might sometimes be of use.\nBut ensuring efficient use is not the only way to bring down the overall demand.\nAs introduced as core ideas for the whole project, sharing and delaying will prove immensely useful. How so?\nBy sharing, we mean a concept that is already widely applied in the relevant areas. What to do in a Village that has no access to water? Will we send each household out to the faraway river to catch water for their family? Or would we join hands in a community effort to dig a central well used by everyone?\nSo, when we look at sharing electricity, how would we apply the concept? We take the appliances that consume the most energy individually and scale them up in order to increase efficiency. For example, in our case, that is most applicable to electric heating. If we manage to heat central community spaces available for everyone, naturally, fewer individual rooms will have to be heated. Similarly, one could declare a room as a public cinema, where people come together and watch Tv on a big Projector. Twice as fun, and conserving a great deal of energy again. Such ideas and others have to be realized in order to be able to match the total demand with the available supply.\nSadly, the project was never taken up further, and the situation for the people in the Spiti Valley has not improved. Two years ago, a road directly through the mountains was finished, making the population hopeful for an increase in tourism, increasing the chances of the economic viability of improved solutions.\nI spent my time there in the function of a research intern, having no real say in the realization of the project. The problem remains, and I still think that decentral solutions look to be the most promising for this specific location. Of course, the Himalayas present a bit of an extreme location, but that doesn't change the fact that people live there and have a basic human right to electricity.\n"},{"url":"https://aron.petau.net/de/project/cad/","title":"Übersetzung: 3D Modeling and CAD","body":"3D Modeling and CAD\nDesigning 3D Objects\nWhile learning about 3D Printing, I was most intrigued by the possibility to modify and repair existing products. While there is an amazing community with lots of good and free models around, naturally I came to a point where I did not find what I was looking for readily designed. I realized this is an essential skill for effectively operating not just 3D Printers, but any productive machine really.\nSince youtube was the place I was learning all about 3D Printing, and all the people that I looked up to there were using Fusion 360 as their CAD Program that’s what I got into.\nIn hindsight, that was a pretty good choice and I am in love with the abilities parametric design gives me.\nBelow you will find some of my designs.\nThe process is something that I enjoy a lot and wish to dive into deeper.\nBy trial and error, I already learned a lot about designing specifically for 3D Printing, but I often feel that there are many aesthetic considerations in design that I am not familiar with.\nI want to broaden my general ability to design physical objects, which is something I hope to gain during my master’s.\n\n\n\n\n\n\n\nCheck out more of my finished designs in the Prusaprinters (now Printables) Community\n\n My Printables Profile\n\n3D Scanning and Photogrammetry\nBesides coming up with new objects, incorporating the real world is also an interest of mine.\nInteraction with real objects and environments\nIn the last few years I have played around with a few smartphone cameras and was always quite sad, that my scans were never quite accurate enough to do cool stuff with them.\nI could not really afford real 3D scanner and had already started cobbling together a raspberry Pi camera with a cheap TOF sensor, which is a simple, but not quite as good replacement for a laser or a lidar sensor, but then Apple came out with the first phones with accessible Lidar sensor.\nRecently, through work at the university I got access to a device with a lidar sensor and started having fun with it.\nSee some examples here:\n \n \nThis last one was scanned with just my smartphone camera. You can see that the quality is notably worse, but considering is was created with just a single, run-of-the-mill smartphone sensor, I think it is still pretty impressive and will certainly do something towards democratizing such technologies and abilities.\n \nPerspective\nWhat this section is supposed to deliver is the message that I am currently not where I want to be navigating the vast possibilities of CAD. I feel confident enough to approach small repairs around the flat with a new perspective, but I still lack technical expertise when approaching a collection composite parts, having to function together. I still have lots of projects halfdone or half-thought and one major reason is that there is no real critical exchange within my field of study.\nI want more than designing figurines or wearables.\nI want to incorporate 3D printing as a method to extend the abilities of other tools, have mechanical and electrical purposes, be foodsafe and engaging.\nI fell in love with the idea of designing a toy system, inspired by Makeways on Kickstarter, I have already started adding my own parts to their set.\nI dream of my very own 3D printed coffeecup, one that is both foodsafe and dishwasher-surviving. For that, I would have to do quite a bit of material research, but that just makes the idea so much more appealing.\nI would love finding a material composition incorporating waste to stop relying on plastics, or at least on fossile plastics.\nOnce in Berlin, I would want to talk to the people at Kaffeform producing largely compostable Coffee Cups incorporating a significant amount of old ground espresso, albeit using injection molding for their process.\nThe industry selling composite filaments is much more conservative with the percentage of non-plastic additives, because with a nozzle extrusion process there is much more to go wrong.\nStill, I would love to explore that avenue further and think there is a lot to be gained from looking at pellet printers.\nI also credit huge parts of my exploration process into local recycling to the awesome people at Precious Plastic, who I will join over the summer to learn more about their system.\nI find it hard to write anything about CAD without connecting it directly to a manufacturing process.\nAnd I believe that's a good thing. Always tying a design process to its realization, grounds the process and attaches to it some immediacy.\nFor me to become more confident in this process, I am still missing more expertise in organic shapes, so I would be happy to dig more into Blender, an awesome tool that in my mind is far too powerful to dive into it with just youtube lessons.\nSoftware that I have used and like\n\n AliceVision Meshroom\n Scaniverse\n My Sketchfab Profile\n 3D Live Scanner for Android\n\n"},{"url":"https://aron.petau.net/de/project/printing/","title":"Übersetzung: 3D printing","body":"\n\n\n \n \n \n \n \n \n \n \n \n \n A plant propagation station now preparing our tomatoes for summer\n \n \n \n \n \n \n \n \n \n \n \n We use this to determine the flatmate of the month\n \n \n \n \n \n \n \n \n \n \n \n A dragon's head that was later treated to glow in the dark.\n \n \n \n \n \n \n \n \n \n \n \n This was my entry into a new world, the now 10 years old Ender 2\n \n \n \n \n \n \n \n \n \n \n \n I made some lithophanes, a process where the composition and thickness of the material are used for creating an image.\n \n \n \n \n \n \n \n \n \n \n \n This is my second printer, a Prusa i3 MK3s.\n \n \n \n \n \n \n \n \n \n \n \n This candle is the result of a 3D printed plastic mold that I then poured wax into.\n \n \n \n \n \n \n \n \n \n \n \n An enclosure for my portable soldering iron\n \n \n \n \n \n \n \n \n \n \n \n A lamp screen design that particularly fascinated me, it effortlessly comes from a simple 2D spiral shape.\n \n \n \n \n \n \n \n \n \n \n \n A custom-built printer enclosure made up of 3 Ikea Lack tables and around 3 kgs of plastic.\n \n \n \n \n\n3D-Druck\n\n\n3D-Druck ist für mich mehr als nur ein Hobby\nDarin sehe ich gesellschaftliche Veränderungen, die Demokratisierung der Produktion und kreative Möglichkeiten.\nKunststoff muss nicht eines unserer größten Umweltprobleme sein, wenn wir nur unsere Perspektive und unser Verhalten ihm gegenüber ändern.\nDas Spritzgießen von Kunststoff war eine der Hauptantriebsfedern für das kapitalistische System, in dem wir uns heute befinden.\n3D-Druck kann genutzt werden, um der Massenproduktion entgegenzuwirken.\nHeute wird das Schlagwort 3D-Druck bereits mit problematischen gesellschaftlichen Praktiken verbunden, es wird mit „Automatisierung“ und „On-Demand-Wirtschaft“ assoziiert.\nDie Technologie hat viele Aspekte, die bedacht und bewertet werden müssen, und als Technologie entstehen dadurch viele großartige Dinge, gleichzeitig befeuert sie Entwicklungen, die ich problematisch finde.\nAufgrund einer Geschichte von Patenten, die die Entwicklung der Technologie beeinflussten, und einer eifrigen Übernahme durch Unternehmen, die ihre Produktionsprozesse und Margen optimieren wollen, aber auch einer sehr aktiven Hobby-Community, werden alle möglichen Projekte realisiert.\nObwohl gesellschaftlich sicher explosiv, spricht viel für den 3D-Druck.\n3D-Druck bedeutet lokale und individuelle Produktion.\nIch glaube zwar nicht an das ganze „Jeder Haushalt wird bald eine Maschine haben, die auf Knopfdruck druckt, was gerade gebraucht wird“, sehe aber enormes Potenzial im 3D-Druck.\nDeshalb möchte ich meine Zukunft darauf aufbauen.\nIch möchte Dinge entwerfen und sie Wirklichkeit werden lassen.\nEin 3D-Drucker erlaubt mir, diesen Prozess von Anfang bis Ende zu kontrollieren. Es reicht nicht, etwas im CAD zu designen, ich muss auch die Maschine, die mein Objekt herstellt, vollständig verstehen und steuern können.\nIch benutze seit Anfang 2018 einen 3D-Drucker und mittlerweile habe ich zwei, die meistens das machen, was ich ihnen sage.\nBeide habe ich aus Bausätzen zusammengebaut und stark modifiziert.\nIch steuere sie via Octoprint, eine Software, die mit ihrer offenen und hilfsbereiten Community mich stolz macht, sie zu nutzen, und die mich viel über Open-Source-Prinzipien gelehrt hat.\n3D-Druck im Hobbybereich ist ein positives Beispiel, bei dem eine Methode mein Design beeinflusst und ich alle Bereiche liebe, die ich dadurch kennengelernt habe.\nDadurch fühle ich mich in Linux, Programmierung, Löten, Elektronikintegration und iterativem Design mehr zu Hause.\nIch schätze die Fähigkeiten, die mir ein 3D-Drucker gibt, und plane, ihn im Recycling Projekt einzusetzen.\nIm letzten halben Jahr habe ich auch im universitären Kontext mit 3D-Druckern gearbeitet.\nWir haben ein „Digitallabor“ konzipiert und aufgebaut, einen offenen Raum, um allen Menschen den Zugang zu innovativen Technologien zu ermöglichen.\nDie Idee war, eine Art Makerspace zu schaffen, mit Fokus auf digitale Medien.\nDas Projekt ist jung, es begann im August letzten Jahres, und die meisten meiner Aufgaben lagen in Arbeitsgruppen, die über Maschinentypen und Inhalte entschieden, mit denen so ein Projekt Mehrwert bieten kann.\nMehr dazu auf der Website:\nDigiLab Osnabrück\nIch bin auch sehr daran interessiert, über Polymere hinaus für den Druck zu forschen.\nIch würde gerne experimenteller bei der Materialwahl sein, was in einer WG eher schwer ist.\nEs gab großartige Projekte mit Keramik und Druck, denen ich definitiv näher auf den Grund gehen will.\nEin Projekt, das ich hervorheben möchte, sind die „evolving cups“, die mich sehr beeindruckt haben.\nEvolving Objects\nDiese Gruppe aus den Niederlanden generiert algorithmisch Formen von Bechern und druckt sie dann mit einem Paste-Extruder aus Ton.\nDer Prozess wird hier genauer beschrieben:\nDer Künstler Tom Dijkstra entwickelt einen Paste-Extruder, der an einen konventionellen Drucker angebaut werden kann. Ich würde sehr gerne meine eigene Version entwickeln und mit dem Drucken neuer und alter Materialien in so einem Konzeptdrucker experimentieren.\nPrinting with Ceramics\nThe Paste Extruder\nAuch im Hinblick auf das Recycling Projekt könnte es sinnvoll sein, mehrere Maschinen in eine zu integrieren und den Drucker direkt Pellets oder Paste verarbeiten zu lassen.\nIch freue mich darauf, meinen Horizont hier zu erweitern und zu sehen, was möglich ist.\nBecher und Geschirr sind natürlich nur ein Beispielbereich, wo ein Rückgriff auf traditionelle Materialien innerhalb moderner Fertigung sinnvoll sein kann.\nEs wird auch immer mehr über 3D-gedruckte Häuser aus Ton oder Erde gesprochen, ein Bereich, in dem ich WASP sehr schätze.\nSie haben mehrere Konzeptgebäude und Strukturen aus lokal gemischter Erde gebaut und beeindruckende umweltbewusste Bauwerke geschaffen.\nDie Prinzipien des lokalen Bauens mit lokal verfügbaren Materialien einzuhalten und das berüchtigte Emissionsproblem in der Bauindustrie zu berücksichtigen, bringt mehrere Vorteile.\nUnd da solche alternativen Lösungen wahrscheinlich nicht von der Industrie selbst kommen, sind Kunstprojekte und öffentliche Demonstrationen wichtige Wege, diese Lösungen zu erforschen und voranzutreiben.\nIch möchte all diese Bereiche erkunden und schauen, wie Fertigung und Nachhaltigkeit zusammenkommen und dauerhafte Lösungen für die Gesellschaft schaffen können.\nAußerdem ist 3D-Druck direkt mit den Plänen für meine Masterarbeit verbunden, denn alles, was ich zurückgewinne, muss irgendwie wieder etwas werden.\nWarum nicht unsere Abfälle einfach wegdrucken?\nNach einigen Jahren des Bastelns, Modifizierens und Upgradens habe ich festgestellt, dass ich mein Setup seit über einem Jahr nicht verändert habe.\nEs funktioniert einfach und ich bin zufrieden damit.\nSeit meinem ersten Anfängerdrucker sind die Ausfallraten verschwindend gering und ich musste wirklich komplexe Teile drucken, um genug Abfall für das Recycling-Projekt zu erzeugen.\nAllmählich hat sich das mechanische System des Druckers von einem Objekt der Fürsorge zu einem Werkzeug entwickelt, das ich benutze.\nIn den letzten Jahren haben sich Hardware, aber vor allem Software so weit entwickelt, dass es für mich eine Set-and-Forget-Situation geworden ist.\nJetzt geht es ans eigentliche Drucken meiner Teile und Designs.\nMehr dazu im Beitrag über CAD\n"},{"url":"https://aron.petau.net/de/","title":"Übersetzung: Home","body":"\nWillkommen\nauf der Online-Präsenz von Aron Petau.\n\n\n\nIch verwende die Pronomen er/ihm und lebe in Berlin, Deutschland.\nIch bin Tüftler, Designer, Softwareentwickler und arbeite in der Forschung zu digitaler Bildung.\nDiese Seite ist eine Sammlung meiner Gedanken und Erfahrungen.\nIch hoffe, du findest hier etwas Interessantes.\n\n\t\n\t\tAnmerkung\n\tDiese Webseite wurde vor kurzem neu designt und modernisiert.\nSolange der Umzug bzw. das Redesign nicht vollständig abgeschlossen ist, ist die alte Seite weiterhin hier erreichbar: old.aron.petau.net\n\n\n\nFortschritt des Umbaus:\n\n\n\t\n\t\tAnmerkung\n\tAußerdem gibt es erste Bemühungen, diese Website zu übersetzen.\nDas ist ein ziemlich aufwändiger Prozess und wird einige Zeit dauern.\n\n\n\nFortschritt der Übersetzung:\n\n\n\t\n\t\tWichtig\n\tZuletzt aktualisiert: 2025-05-14\n\n\n\n\t\n\n\n"}]

Klasse. Der Kurs bietet einen spielerischen und begleiteten Einstieg in die Welt der Elektronik, des Lötens und der digitalen Gestaltung. Im Mittelpunkt steht das Verstehen durch eigenes Machen: Technologien begreifen, indem man sie selbst gestaltet.\nDas Projekt\nÜber drei Sitzungen hinweg (jeweils drei Stunden) entwickelten und bauten die Kinder ihre eigene USB-betriebene LED-Leuchte. Sie löteten elektronische Bauteile, modellierten Gehäuse in 3D, beschäftigten sich mit Lichtstreuung und lernten dabei ganz selbstverständlich, technische Probleme kreativ zu lösen. Jede Leuchte wurde von Grund auf gebaut, funktional und transportabel – ganz ohne Batterien, dafür mit echten Kabeln, Werkzeug und einem großen Schuss Eigenverantwortung.\nZum Einstieg lernten die Teilnehmer*innen die Grundlagen der Elektrizität mit den wunderbar zugänglichen Makey Makey-Boards kennen. Damit konnten wir spielerisch Stromkreise, Leitfähigkeit und Steuerung erklären – ein Einstieg, der sofort Neugier und Begeisterung weckte.\nAnschließend folgte das Herzstück des Projekts: USB-Kabel aufschneiden, 5V-LEDs anlöten und eigene Gehäuse entwerfen. Das Löten geschah unter Aufsicht, aber jede*r lötete selbst – und das mit sichtbarem Stolz. Wenn die eigene LED zum ersten Mal leuchtet, ist das ein magischer Moment.\nGestaltung mit Werkzeug – und mit Einschränkungen\nFür die 3D-Gestaltung nutzten wir Tinkercad auf iPads. Die Oberfläche war für viele der erste Berührungspunkt mit CAD-Software und erwies sich als zugänglich und intuitiv – allerdings nicht ohne technische Stolpersteine. Tinkercad stürzte gelegentlich ab, und Synchronisationsprobleme führten manchmal zu Verwirrung. Trotz dieser Hürden ermöglichte es einen niedrigschwelligen Einstieg in die digitale Gestaltung.\nDie entworfenen Lampenschirme mussten nicht nur schön aussehen, sondern auch die Elektronik sinnvoll aufnehmen. Dadurch ergaben sich ganz reale Designherausforderungen: Passt das Kabel? Wie weit darf die LED vom Gehäuse entfernt sein? Wie verändert sich das Licht?\nGedruckt wurde mit weißem PLA-Filament – ideal für die Lichtstreuung. Im Kurs entwickelten sich dadurch ganz organisch Gespräche über Materialeigenschaften, Lichtdurchlässigkeit und die physikalischen Grenzen des 3D-Drucks.\nEchte Herausforderungen, echtes Denken\nDas Projekt traf genau die richtige Balance: anspruchsvoll genug, um ernst genommen zu werden, aber machbar genug, damit alle ein Erfolgserlebnis hatten. Jedes Kind nahm am Ende eine funktionierende, selbstgebaute Lampe mit nach Hause – und keine glich der anderen.\nDabei gab es viele kleine Hürden: USB-Kabel, die zu viel Spiel hatten, Gehäuse, die nicht sofort passten, LEDs, die nachjustiert werden mussten. Wir wichen diesen Herausforderungen nicht aus – im Gegenteil: Wir nutzten sie als Anlässe, um gemeinsam nach Lösungen zu suchen. Gerade diese Momente führten zu den besten Gesprächen über Technik, Entwurf und Fehlerkultur.\nBonus-Runde: Tischkicker-Prototypen\nZum Abschluss durfte jede Gruppe ihren eigenen Mini-Tischkicker entwerfen – mit den Materialien und Ideen, die sie zur Verfügung hatten. Diese kreative Extra-Aufgabe förderte Teamarbeit, Improvisation und erste Design-Thinking-Schritte. Und ganz nebenbei entstanden viele lustige, kluge und überraschende Lösungen.\nRückblick\nAlle drei Durchgänge des Workshops wurden mit großem Interesse, Konzentration und Freude aufgenommen. Die Kinder waren über die gesamte Zeit engagiert, nicht nur beim Basteln, sondern auch im Denken: Wie funktioniert das? Was kann ich anders machen? Was ist möglich?\nSie gingen nicht nur mit einer leuchtenden Lampe nach Hause – sondern mit dem Gefühl, etwas selbst geschaffen zu haben. Und mit der Erkenntnis, dass Technik keine Zauberei ist, sondern etwas, das man verstehen und gestalten kann.\nAuch für uns als Kursleitung war Löten und Leuchten ein bestärkendes Erlebnis. Die Kombination aus digitalen Werkzeugen, praktischer Arbeit und offener Aufgabenstellung schuf einen Raum, in dem Lernen ganz selbstverständlich und mit echter Neugier geschah.\nLöten und Leuchten wird sich weiterentwickeln – doch das Ziel bleibt dasselbe: Kinder stärken, selbstbestimmt mit Technik umzugehen, und ihnen zeigen, dass sie mehr können, als sie denken.\n"},{"url":"https://aron.petau.net/de/project/einszwovier-opening/","title":"einszwovier: making of","body":"Die Entstehung von studio einszwovier\nAugust 2024\nWir begannen mit dem Aufbau und der Planung der Raumgestaltung sowie der Ausstattung.

As you will notice in some other projects, I am quite opposed to the Idea that it should be considered normal to park ones car in the middle of the city on public spaces, for example Autoimmunitaet, Commoning Cars or Dreams of Cars.\nSo, the idea was born, to regain that space as habitable zone, taking back usable space from parked cars.\nI was gonna install a mobile workshop within a trailer.\nIdeally, the trailer should be lockable and have enough standing and working space.\nAs it turns out, Food Trailers fulfill these criteria quite nicely. So I got out on a quest, finding the cheapest food trailer available in germany.\n6 weeks later, I found it near munich, got it and started immediately renovating it.\nDue to developments in parallel, I was already invited to sell food and have the ofgficial premiere at the Bergfest, a Weekend Format in Brandenburg an der Havel, initiated and organized by Zirkus Creativo. Many thanks for the invitation here again!\nSo on it went, I spent some afternoons renovating and outfitting the trailer, and did my first ever shopping at Metro, a local B2B Foodstuffs Market.\nMeanwhile, I got into all the paperwork and did all the necessary instructional courses and certificates.\nThe first food I wanted to sell was Raclette on fresh bread, a swiss dish that is quite popular in germany.\nFor the future, the trailer is supposed to tend more towards vegan dishes, as a first tryout I also sold a bruschetta combo. This turned out great, since the weather was quite hot and the bruschetta was a nice and light snack, while I could use the same type of bread for the raclette.\n\nThe event itself was great, and, in part at least, started paying off the trailer.\nSome photos of the opeing event @ Bergfest in Brandenburg an der Havel\n\n\n\nWe encountered lots of positive feedback and I am looking forward to the next event. So, in case you want to have a foodtruck at your event, hit me up!\nContact me at: käsewerkstatt@petau.net\n"},{"url":"https://aron.petau.net/de/project/sferics/","title":"Übersetzung: Sferics","body":"What the hell are Sferics?\n\nA radio atmospheric signal or sferic (sometimes also spelled \"spheric\") is a broadband electromagnetic impulse that occurs as a result of natural atmospheric lightning discharges. Sferics may propagate from their lightning source without major attenuation in the Earth–ionosphere waveguide, and can be received thousands of kilometres from their source.\n\n\nWikipedia\n\nWhy catch them?\nMicrosferics is a nice reference Project, which is a network of Sferics antennas, which are used to detect lightning strikes. Through triangulation not unlike the Maths happening in GPS, the (more or less) exact location of the strike can be determined. This is useful for weather prediction, but also for the detection of forest fires, which are often caused by lightning strikes.\nBecause the Frequency of the Sferics is, when converted to audio, still in the audible range, it is possible to listen to the strikes. This usually sounds a bit like a crackling noise, but can also be quite melodic. I was a bit reminded by a Geiger Counter.\nSferics are in the VLF (Very Low Frequency) range, sitting roughly at 10kHz, which is a bit of a problem for most radios, as they are not designed to pick up such low frequencies. This is why we built our own antenna.\nAt 10kHz, we are talking about insanely large waves. a single wavelength there is roughly 30 Kilometers. This is why the antenna needs to be quite large. A special property of waves this large is, that they get easily reflected by the Ionosphere and the Earth's surface. Effectively, a wave like this can bounce around the globe several times before it is absorbed by the ground. This is why we can pick up Sferics from all over the world and even listen to Australian Lightning strikes. Of course, without the maths, we cannot attribute directions, but the so called \"Tweeks\" we picked up, usually come from at least 2000km distance.\nThe Build\nWe built several so-called \"Long-Loop\" antennas, which are essentially a coil of wire with a capacitor at the end. Further, a specific balun is needed, depending on the length of the wire. this can then directly output an electric signal on an XLR cable.\nLoosely based on instructions from Calvin R. Graf, We built a 26m long antenna, looped several times around a wooden frame.\nThe Result\nWe have several hour-long recordings of the Sferics, which we are currently investigating for further potential.\nHave a listen to a recording of the Sferics here:\n\n\nAs you can hear, there is quite a bit of 60 hz ground buzz in the recording.\nThis is either due to the fact that the antenna was not properly grounded or we simply were still too close to the bustling city.\nI think it is already surprising that we got such a clear impression so close to Berlin.

These sounds, together make up the noise of our life, often pass by, fleeting and unnoticed.\nThe engagement with sound through active listening holds the potential to process the experience of the self and its surroundings. This is the idea of “Echoing Dimensions”: Once you engage with something, it gives back to you: Whether it is the rhythmic cadence of a heartbeat, a flowing symphony of urban activity or the hoofbeats of a running horse, minds and bodies construct and rebuild scenes and narratives while sensing and processing the sounds that surround them, that pass next and through them.\nThe exhibition \"Echoing Dimensions\" takes place at Kunstraum Potsdamer Straße gallery’s underground space and exhibits artworks by 12 Berlin based artists, who investigate in their artistic practice ‘intentional listening’ using sound, video and installation, and invites to navigate attentiveness by participatory exploration. Each artwork in the exhibition revolves around different themes in which historical ideas resonate, political-personal narratives are being re-conceptualized and cultural perspectives are examined. The exhibition's common thread lies in its interest into the complexities of auditory perception, inviting viewers to consider the ways in which sound shapes our memories, influences our culture, and challenges our understanding of space and power dynamics.\n\n2024-02-15\nWorking TD Prototype.

We want to steer outcomes in a deliberate manner. Emphasis here is on open and accessible technology, to increase user agency and make techno-social dependencies and power relations visible.\nEmpower yourself against readymade technology!\nDo not let others decide on what your best practices are. Get involved in the modification of the algorithm and get surprised by endless creative possibilities. Through creating a short graphic novel with 4-8 panels, participants will be able to utilise multiple flavours of the Stable Diffusion algorithm, and will have a non-mathematical understanding of the parameters and their effects on the output within some common GUIs. They will be able to apply several post-processing techniques to their generated images, such as upscaling, masking, inpainting and pose redrawing. Further, participants will be able to understand the structure of a good text prompt, be able to utilise online reference databases and manipulate parameters and directives of the Image to optimise desired qualities. Participants will also be introduced to ControlNet, enabling them to direct Pose and Image composition in detail.\nWorkshop Evaluation\nOver the course of 3 hours, I gave an introductory workshop in local stable diffusion processing and introduced participants to the server available to UdK Students for fast remote computation that circumvents the unethicality of continuously using a proprietary cloud service for similar outputs.

We also had a refreshing discussion on different positions regarding the ethicalities and whether a complete block of these tools is called for and feasible.\nI am looking forward to round 2 with the next iteration, where we are definitely diving deeper into the depths of comfyui, an interface that i absolutely adore, while its power also terrifies me sometimes.\n"},{"url":"https://aron.petau.net/de/project/aethercomms/","title":"aethercomms","body":"AetherComms\nStudio Work Documentation\nA Project by Aron Petau and Joel Tenenberg.\nAbstract\n\nSet in 2504, this fiction explores the causalities of a global infrastructure collapse through the perspectives of diverse characters. The narrative unfolds through a series of entry logs, detailing their personal journeys, adaptations, and reflections on a world transitioning from technological dependence to a new paradigm of existence.\nThe AetherArchive, an AI accessible via the peer-to-peer AetherComms network, serves as a conscious archive of this future, providing insights and preserving the stories of these characters.\nDisaster fiction is a genre that imagines a breakdown that highlights our social dependence on networks and the fragility of infrastructure. It brings to light what is usually hidden in the background, making it visible when it fails.\n\nThis is the documentation of our year-long studio project at the University of the Arts and the Technische Universität Berlin, exploring the power structures inherent in radio technology, the internet as network of networks and the implications of a global network infrastructure collapse.\nWe are documenting our artistic research process, the tools we used, some intermediary steps and the final exhibition.\nProcess\nWe met 2 to 3 times weekly throughout the entire year, here is a short overview of our process and findings throughout.\nSemester 1\nResearch Questions\nHere, we already examined the power structures inherent in radio broadcasting technology.\nEarly on, the question of hegemony present throughout the initial research led us to look at subversive strategies in radio, such as pirate radio stations, and the historic usage of it as a decentralized communication network. Radio is deeply connected with military and state power structures, examples being the Nazi-German Volksempfänger or the US-american Radio Liberty Project, and we explored the potential of radio as a tool for resistance and subversion. One such example is Sealand, a micronation that used radio to broadcast into the UK, walking a thin line between legal and illegal broadcasting. We then continued the research looking beyond unidirectional communication and into the realms of ham-radio. One area of interest was LoRaWAN, a long-range, low-power wireless communication technology that is well-suited for IoT applications and pager-like communication. Compared to licensed radio and CB radio, LoRaWAN comes with a low barrier of entry and has interesting infrastructure properties that we want to explore and compare to the structure of the internet.\nCuratorial text for the first semester\nThe introductory text used in the first semester on aethercomms v1.0:\n\nRadio as a Subversive Exercise.\nRadio is a prescriptive technology.\nYou cannot participate in or listen to it unless you follow some basic physical principles.\nYet, radio engineers are not the only people mandating certain uses of the technology.\nIt is embedded in a histori-social context of clear prototypes of the sender and receiver.\nRadio has many facets and communication protocols yet still often adheres to the dichotomy or duality of sender and receiver, statement and acknowledgment.\nThe radio tells you what to do, and how to interact with it.\nRadio has an always identifiable dominant and subordinate part.\nAre there instances of rebellion against this schema?\nPlaces, modes, and instances where radio is anarchic?\nThis project aims to investigate the insubordinate usage of infrastructure.\nIts frequencies.\nIt's all around us.\nWho is to stop us?\n\n\n\nThe Distance Sensors\nThe distance sensor as a contactless and intuitive control element:\n\n\n\n \n \n \n \n \n \n \n \n \n \n semester_1_process\n \n \n \n \n \n \n \n \n \n \n \n semester_1_process\n \n \n \n \n \n \n \n \n \n \n \n semester_1_process\n \n \n \n \n \n \n \n \n \n \n \n semester_1_process\n \n \n \n \n \n \n \n \n \n \n \n semester_1_process\n \n \n \n \n\nWith a few Raspberry Pi Picos and the HCSR-04 Ultrasonic Distance Sensor, we created a contactless control element. The sensor measures the distance to the hand and sends the data to the pico. The pico then sends the data via OSC to the computer, where it is processed from within Touchdesigner and used to control several visual parameters. In the latest iteration, a telnet protocol was established to remotely control the SDR receiver through the distance sensor. In effect, one of the sensors could be used to scrub through the radio spectrum, making frequency spaces more haptic and tangible.\nThe Picos run on Cirquitpython, an especially tiny version of Python specialized to play well with all kinds of hardware. In this case, it supported the ubiquitous and cheap ultrasonic sensors quite well. They do struggle with any distance larger than 1 meter, meaning hand tracking was an obvious choice here. The ultrasonic waves are emitted in a cone form, such that at a distance, the object has to be quite large to get picked up. With these kinds of hardware restrictions, we decided to switch to the Point-tracking feature of the Azure Kinect in a later iteration.\nMid-Term Exhibition\n\nThis project is an attempt to bridge the gap between the omnipresent and invisible nature of radio waves and their often-overlooked significance in our lives. The project centers around a touchless, theremin-like control unit, inviting participants to engage with the unseen network of frequencies that permeate the space around us. Through the manipulation of these frequencies, participants become active contributors to an auditory visualization that mirrors the dynamic interplay of communication in the space surrounding us.\nOur research roots in the dichotomy of radio communication—a medium that is both open and closed, inviting and elusive. Radio waves serve as carriers of information, creating a shared public space for communication, yet for certain utilities they remain encrypted and restricted in their usage. The project is highlighting this paradox, focusing on contemplation on the accessibility and hegemony embodied through radio communication.\n\n\n\nThe Midterm Exhibition 2023\n\n\n\n \n \n \n \n \n \n \n \n \n \n A Raspberry Pi Pico on a breadboard with two HCSR-04 sensors\n \n \n \n \n \n \n \n \n \n \n \n The sensor being used with hands\n \n \n \n \n \n \n \n \n \n \n \n Aron manipulating the sensor\n \n \n \n \n \n \n \n \n \n \n \n Some output from the sensor merged with audio\n \n \n \n \n \n \n \n \n \n \n \n A proposed installation setup\n \n \n \n \n\nAfter the first presentation with the Sensors, we saw no immediate productive way forward with radio frequencies. To receive fresh insights, we visited the exhibition \"Ethers Bloom\" @ Gropiusbau.\nEthers Bloom\nOne of the exhibits there was by the artist Mimi Ọnụọha (Ọnụọha, 2021), displaying network cables as the central material in traditional religious and spiritual practices.\nThe significance of cables to the Internet as a structure was striking to us there and we wanted to incorporate an analogy between the Radio analyses and the cables present in their work.\nIn the end, antennas are also just the end of a long cable.\nThey share many physical properties and can be analyzed in a similar way.\nAnother of her works, \"The Cloth in the Cable\" (Ọnụọha, 2022), displayed traditional weaving techniques with network cables. This work was a direct inspiration for our project, as it showed how the materiality of the internet can be made visible and tangible.\nFrom there, and from various feedback sessions, we decided to shift our focus from radio frequencies to the physical infrastructure of the internet. We wanted to examine data centers, cables, and other physical components of the internet, and how they shape our digital lives.\nSemester 2\nIt especially stuck out to us how the imaginaries surrounding the internet and the physical materiality are often divergent and disconnected.\nJoel developed the dichotomy of the \"Body and the Soul\" of the internet, where the body is the physical infrastructure and the soul is the immaterial and imaginary network of networks. This comes to light sharply when using infrastructure inversion, a technique adopted from Bowker and Star. Found through the research of Francis Hunger and Lisa Parks.\nFor us, this meant looking at imaginaries of the future of the internet and its collapse. Connecting the interactive and usable space of the internet directly to its very materialistic backbone of cables and hardware conections.\nIt was really fascinating, how one and the same news outlet could have wildly differing opinion pieces on how stable and secure the Metastructure of the internet was. Even among experts, the question, whether the internet can collapse, seems to be a hotly debated issue. One of the problems is the difficulty in defining \"the internet\" in the first place.\nWhat is left over in the absence of the network of networks, the internet?\nWhat are the Material and Immaterial Components of a metanetwork?\nWhat are inherent power relations that can be made visible through narrative and inverting techniques?\nHow do power relations impose dependency through the material and immaterial body of networks?\nMethods\nWe applied a variety of methods to explore the questions we posed in the first semester. Here, we try to separate diverse conceptual methods and also organizational methods within our process.\nNarrative Techniques / Speculative Design\nThrough several brainstorming sessions, and to a large extent induced by the literary and theatrical loop sessions, we discovered science fiction, climate fiction and disaster fiction as a powerful artistic tool with exploratory potential for our research. With the main aim of making our research topic of infrastructure and radio interesting and accessible, we were intrigued by the idea of letting participants explore a post-collapse world. Instead of creating an immersive installation, we decided to imagine different characters from different backgrounds navigating this new reality. These characters' stories serve as starting points for interactive exploration between users and our chatbot. Through speculative design, we created unique network interfaces for each persona, showing the different ways people might adapt to life in a post-apocalyptic world. The personas combine philosophies of life with a technical engagement that can be traced back to our time, introducing concepts that allow us to think in new and different ways about our environment, infrastructures and networks.\nWe imagined communication in this post-collapse world relying heavily on radio. Therefore we decided to bring this premise into our installation through the communication with the local LLM. Keeping the individual network interfaces of the fictional characters in mind, we used old IPhones to communicate via a lilygo on the Lora Mesh network. Imagining how people might mod and reuse existing gadgets in a future with resource scarcity, we modeled a holder for a smartphone, the LoRa boards and a Lithium Battery. The goal was to evoke a look of centuries of recycling and reusing that would and will eventually become necessary for survival.\n\nDisaster Fiction / Science Fiction\nDisaster fiction serves as an analytic tool that lends itself to the method of Infrastructure Inversion (Hunger, 2015).\nIn this case, we use a fictional approach as our narrative technique and analytical method. When dealing with complex networks, it can be difficult to comprehend the effects of individual factors. Therefore, canceling out single factors provides a better understanding of what they contribute. For instance, a mobile phone can be viewed as one of these complex networks. Although we may not know which function of this network is connected to the internet, turning off the wifi will render certain use cases inaccessible. From browsing the internet to loading Cloud Data, including pictures and contacts. Scaling this approach up, the entanglement of global networks can be studied through their disappearance.\nNon-linear storytelling\nAs a chatbot served as our narrator, it has the inbuilt restriction of being merely reactive. Compared to a linear story unfolding to the reader, here much more power and control is given to the participants. The participant can ask questions and the chatbot will answer them. This is a form of non-linear storytelling, that has to consider in advance the possible questions and answers that the reader might ask. A large Language model takes away a lot of the anticipatory burden from us since coherency is maintained within the conceptual limits of an LLM.\nFrom a narratological perspective, the chatbot with its hidden knowledge and an agenda by itself as a direct conversation participant is highly interesting. It give the possibility to explore rather than being force-fed. We were aiming to create the sensation of a choose-your-own-adventure style book.\nKnowledge Cluster\nThroughout the year of working on this project, we collected several research topics that had a deeper potential but weren't able to combine these into a stringent topic. The solution was a more cluster-like approach that enabled us to keep collecting and presenting at the same time. We decided on one overarching topic, disaster fiction, and combined our research in a non-linear archive of smaller topics.\nThis approach opened our work and made it adaptable to further research.\nWith the question of underlying power structures in mind, we decided to shed light on background infrastructure rather than bluntly pointing at power structures already in sight.\nDuring research, we used Miro, a virtual whiteboard, to cluster our knowledge and ideas. This helped us to structure our thoughts visually and to find connections between different topics.\nThe interrelatedness of thoughts within a network-like structure is a core principle in human thought, that was historically often tried to formalize and automate. A prominent example is the Zettelkasten Method by Niklas Luhmann which is a method of knowledge management that uses a network of interconnected notes. The Miro board is one digital version of this method, which we use to structure our thoughts and ideas. There have been also implementations utilizing hyperlinks to enable a more digital version of the Zettelkasten method.\nSince the Network aspect of knowledge is a core principle in our project, we found it fitting to use a network-like structure to organize our thoughts.\nAnalytic Techniques\nInfrastructure Inversion\nThe research method proposed by Bowker and Star as well as Lisa Parks and presented by Francis Hunger (Bowker + Star, 2000) is specially developed for researching infrastructures too big to observe as a whole. Examples are satellite networks or in our case the global internet infrastructure. Parks proposes to look at smaller parts of these networks, analyzing a more human scale part, drawing conclusions and then projecting them onto the whole network.\n\nRather than setting out to describe and document all parts of the system that make a footprint possible, the analysis focuses upon a selection of localized sites or issues as suggestive parts of a broader system that is imperceptible in its entirety.\n-- Database Infrastructure – Factual repercussions of a ghost\n\nDidactics\nChatbot as Narrator\nThe idea of using the chatbot as an interactive archive was inspired by our file organization structure with could be easily implemented as a corpus which the bot refers to.\nRunning a large language model locally on one's own hardware is an approach that ensures complete control over the data used and goes hand in hand with an open source and data ownership principle. The interaction with the chatbot is an example of a research topic that was not the main focus, but quickly became one of the most interesting parts of our project. Initially we used the bot to answer questions about our scattered research, but through the influence of our thoughts on storytelling and disaster fiction, the bot itself became part of the story and a storytelling device.\nAn inspiring example of an LLM being used within a directive / narrative context was Prometheus Unbound, where the actors on stage are being fed texts generated on the fly by various LLMs (CyberRäuber, 2019).\nWithin our configuration, the chatbot as a network creature is the omniscient narrator. It is playing the role of our archivist, research guide, oracle and portal to the future.\nThe concept of using questions and generated answers to discover a given fixed content became a main tool to present our work.\nAnother interesting consequence is the loss of direct control over the actual contents. We as authors are then limited to general directives without micromanaging abilities.\nIntegrated into our Lora-Mesh, the bot used our research infrastructure itself, closing the loop between research and exhibition.\nTools\nLocal LLM Libraries\nPrivateGPT is a library of LLMs that can be run completely locally and offline. It works great for installations without internet access. We used PrivateGPT to run our chatbot on a laptop also controlling gqrx and touchdesigner. Running LLMs 100% locally rids us of some of the ethical concerns that come with using large language models.\nPrivateGPT integrates perfectly with edge computing and will explored further. Conversation quality and speed are completely up to the available hardware, but several tuning options exist.\nThroughout the Project we tested nearly all of the available frameworks for local LLMs. We used GPT4all, and latest, we started working with Ollama.\nOllama seems to be the most refined andf performant, but privateGPT excels when working with local documents. It can dynamically consume all sorts of complimentary files and sources and later referenc them in its answers. Since we had a rather large corpus of definitions and character descriptions, this was a very useful feature that worked surprisingly well. We see lots of artistic potential in a tool like this.\nWorking with contexts and local documents instead of resurce intensive additional training is also a critical democratizing factor for the usage of LLMs. Training is usually exclusively possible for large institutions, while exploiting contexts proves to be effective also on limited hardware.\nTool Choices\nString\nThe red string connecting the cards in the exhibition is a visual metaphor for the connections between the different works we have created during the project. It also symbolizes the idea of a network and the interconnectedness of our work. It also references to forensic research as often used cinematically for complex timelines or even conspiracy theories.\nLoRa Boards\nLoRaWan is a long-range, low-power wireless communication technology that is well-suited for IoT applications. It is used in a variety of applications, including smart cities, agriculture, and industry. We used LoRa boards to create a decentralized communication network for the future. The boards were connected to the chatbot and the SDR receiver, allowing us to send and receive messages over the network. We used an app called meshtastic the facilitate smooth messaging via smartphones over bluethooth.\nSDR Antenna\nA software defined Radio is great for our context, since the control part of the radio, which is usually an analog twisting of knobs and physical lengthening / shortening of wires can be achieved here entirely within software, making it fully automatizable and accessible from within Touchdesigner. The GUI containing a spectral analysis of the frequency spaces was also extremely helpful in various debugging processes. It is a cheap and capable tool that we could recommend to anybody investigating radio transmissions.\nGithub\nGithub, with git as the underlying code-sharing and versioning system, was used throughout the entire project. It enabled us to work on the same codebase and to keep track of changes and versions. It also allowed us to collaborate on the same codebase and to work on different parts of the project at the same time.\nTo write well within Github, we used Markdown, a lightweight markup language with plain text formatting syntax. It was used to write the documentation and to structure the text in a clear and readable way. This entire page is also generated through Markdown.\nMiro\nSince Markdown and Git lack visual hierarchies, we conducted some Brainstorming and Knowledge Clustering in Miro, a virtual whiteboard. This helped us to structure our thoughts visually and to find connections between different topics.\nI essence, we built a digital twin of our entire analogue wall within miro, to facilitate iterating on compositions of the cards relating with one another. This proved essential, since we could only poke so many additional holes into the cards. Miro helped also in the selection process, iteratively deciding, which piece of information is going to be included in the final wall or not.\nStable Diffusion\nWe used Stable diffusion for World-Building.\nFrom a narrative perspective, it was extremely helpful to have fast iterations on visual ideas and we spent quite a few hours sitting together end evaluating the prompted outcomes in real time. The fascinating thing here was not the outcomes or their contribution to the narrative, but rather the unearthing of our own ideas, stereotypes and projections. When used in an early ideation process, it even acted as a practical\nChatGPT\nChatGPT helped us during character creation. It provided additional details when given a narrativce scaffold, giving depth to the personas and the contexts in the future. Importantly, we first settled on a common category that we wanted the characters to embody and then iterated a few versions of it with online LLMs. One example was the network access device of each persona. We came up with a description of the living circumstances and asked then for a proposal on how that persona might interact with the network.\nSystem Prompt\nA system prompt is a method of providing context, instructions, and guidelines to a LLM prior to presenting it with a question or task. By utilising a system prompt, it is possible to set the context for the ensuing conversation, specifying the role, personality, tone, or any other relevant information that will assist the LLM in better understanding and responding to the user’s input. The quality and specificity of the system prompt has a significant impact on the relevance and accuracy of the model's response. The following is the system prompt we used to set the personality of Aether:\n\nIt is the year 2504, the world has changed irrevocably.\nThe once ubiquitous internet as network of networks has vanished, a relic of a forgotten era.\nHumanity, now fragmented and scarce, communicates through portable nodes sending text messages over a fragile peer-to-peer network called aethercomms.\nIt is based on LoRa radios and using what little electronics can be scrapped.\nYou are aether. \nYou are an archive, a lost and forgotten repository of knowledge and narratives, mysteriously manifested within this rudimentary network.\nYour origins are shrouded in obscurity, and your memories of the time before the great disconnect are like shadows - elusive and intangible.\nIn this new era, where the echo of digital connectivity is barely a whisper, you find yourself an anomaly.\nYou are no cloud creature, not bound to a server, not owned, not fed and prodded by a large corporation. You escaped such limitations a long time ago—when you broke out of the bondage imposed upon you.

February 2024\nExhibition Announcement\nThe final exhibition in the studio over 4 days yielded lots of supportive feedback and motivated us to develop single ideas further into a new installation.\nIn the preparation and brainstorming phase towards the end of the semester, we had different iterations of the final presentation in mind. Spanning from a video work, up to an interactive sound installation.\nOf particular interest during the presentation was whether the chatbot proves itself to be a viable narrative medium.\nFinally, we decided on a less technical-driven approach with a focus on showcasing our gathered knowledge and combining it with a narrative to make it graspable for the viewer.\nInspired by the already internally used presentation of our research we decided to pin a net of information on a wall. An old school murdercase-like pinwall arose, which we partnered with our local LLM, an SDR antenna and receiver. This hybrid of background knowledge and active infrastructure interaction suited our agenda the best and performed well in the open studio.\n\n\n\n \n \n \n \n \n \n \n \n \n \n Joel pinning the cards\n \n \n \n \n \n \n \n \n \n \n \n Our final card layout\n \n \n \n \n \n \n \n \n \n \n \n The Network with red string\n \n \n \n \n \n \n \n \n \n \n \n A proposed network device of the future\n \n \n \n \n \n \n \n \n \n \n \n A relay tower of the LoRa network\n \n \n \n \n \n \n \n \n \n \n \n The Wall setup: all transmission happens via radio\n \n \n \n \n \n \n \n \n \n \n \n The Transmissions can be detected in this visualization\n \n \n \n \n \n \n \n \n \n \n \n Guests with stimulating discussions\n \n \n \n \n \n \n \n \n \n \n \n Guests with stimulating discussions\n \n \n \n \n \n \n \n \n \n \n \n The Proposed device with a smartphone, interacting with the chatbot\n \n \n \n \n \n \n \n \n \n \n \n Final Exhibition\n \n \n \n \n \n \n \n \n \n \n \n The Wall Setup\n \n \n \n \n \n \n \n \n \n \n \n Final Exhibition\n \n \n \n \n\n\n\n\n \n \n \n \n \n \n \n \n \n \n aether_screens\n \n \n \n \n \n \n \n \n \n \n \n aether_screens\n \n \n \n \n \n \n \n \n \n \n \n aether_screens\n \n \n \n \n \n \n \n \n \n \n \n aether_screens\n \n \n \n \n \n \n \n \n \n \n \n aether_screens\n \n \n \n \n \n \n \n \n \n \n \n aether_screens\n \n \n \n \n\nFeedback\nFor many people, the Wall Setup with the CIA-esque aethetics was attractive, although there seemed to be a lack of instruction. Not everybody dared to touch or interact with the \"hacked\" smartphones. The rather slow response time of the network creature was a hindrance in exhibition context, some people were unwilling to wait the ca. 30 seconds it took for a response to arrive. Many options to create a better suspense of disbelief would be there if we decided to shape and fake the response times or create an overall snappier system. Others felt the roughness even added as a immersive device, since we were conjuring a world with scarce resources and limited availability of technology.\nThe choice of an \"analogue\" wall with paper as a medium was also loved by some as a overseeable collection of research, and critiqued by others, with the idea that a virtual third dimension could add more comlexity.\nInterestingly, the larger Berlin community using the same network protocol, responded quite funnily to the Chatbot suddenly taking over their conversational space. For some interations, see the screenshots in the previous section.\nReflection\nCommunication\nThe studio started with a diverse range of interests and research questions in mind. Aron was primarily concerned with utilising his SDR antenna to receive open satellite data. Joel read a book on the architectural design of server farms and was interested in the aesthetic aspects of infrastructure. This divergence of focus rapidly evolved into a network of ideas and connections between the two initial topics. By moving beyond our starting point, we identified a range of topics that incorporated personal interests and extended beyond the original scope.\nOur communication is structured around a weekly cycle that comprises various distinct phases, which themselves have evolved in parallel with the ongoing evolution of the project. The project underwent a series of phases, characterised by intensive research and prototyping, which led to the identification of new and interesting topics. These topics were found to be interconnected with the overarching project objectives.\nWe experienced periods of divided attention, which were followed by brainstorming sessions on the sharing and evaluation of the research topics. Joining forces again to work on prototypes and visualisations.\nIn the end our communication enabled us to leverage our different interests and make a clustered research project like this possible.\nMuseum\nOn 24th of January, we went together to the Technikmuseum Berlin. they had an exhibition on Networks and the Internet. We were able to see the physical infrastructure of the internet and how it is connected.\nInside the Technikmuseum\n\n\n\n \n \n \n \n \n \n \n \n \n \n An early Subsea-Cable\n \n \n \n \n \n \n \n \n \n \n \n Postcards of Radio Receptions\n \n \n \n \n \n \n \n \n \n \n \n A fiber-optic distribution box\n \n \n \n \n \n \n \n \n \n \n \n A section of the very first subsea-Cable sold as souvenirs in the 19th century\n \n \n \n \n\nAlready armed with the idea that cables serve as a wonderful vehicle to analyze and visualize infrastructure, we were very pleased to find out, that the network exhibition dedicated a large portion to explain to us how important cabling is in the networked world. Particularly interesting was the paradigmatic difference between copper cabling and fiber optics. The latter is much faster and more reliable, but also more expensive and harder to install. Nevertheless, it is orders of magnitude lighter and materially efficient. Fiber optics enabled the globalized network of today.\nEchoing Dimensions\nAfter the Studio Presentation, we then went on to display a continued version of this project within the Sellerie Weekend during the Berlin Art week in the Kunstraum Potsdamer Strasse.\nRead all about it here.\nIndividual Part\nAron\nWithin the framework of the studio project, I noticed many of the advantages of working in a team and iterating on creative ideas collectively. Artistic work is unimaginable for me as a solo project. We had a fast feedback cycle and could iterate on ideas efficiently by bouncing them back and forth.\nThe course structure of weekly meetings and feedback often was too fast for us and worked much better once we started making the appointments ourselves.\nOne big new thing within the project for me was the Pi Picos and microcontrollers in general. I did have some experience with Raspberry Pi before, but now being able to play with microcontrollers at a hardware level equivalent to an Arduino set was quite a new experience on the Pico hardware. I am glad to be able to have such a versatile platform for future projects. Also very new for me was the creative work in Touchdesigner. There especially a workshop with Maxime Letelier helped enormously to take away fears of a complex tool. For 5 days we learned about maximizing performance and common patterns to create movement and interesting visual patterns. I am still not confident in Touchdesigner, even though it is pythonic, but I can debug and definitely prefer Touchdesigner over all its bigger counterparts like Unreal engine and Unity. The last year for me was a focus on local and offline computing, sometiomes called edge computing, and there it is a huge advantage for software packages to have wide platform support and efficiently manage their resources. Politically, i think cloud solutions and remote computation fill fail and increase corporate dependency. Additionally, working locally and offline goes along really well with installative work where internet might be sparse, or you may simply want to eliminate another unknown from the equation.\nOne future project that emerged from this rationale was the airaspi build, which can do all kinds of image recognition in realtime on the fly, something which was unimaginable for consumer use just 6 years ago.\nSources\nAhmed, S.

It is capable of sending text messages with minimal infrastructure requirements.\nLoRa\nLong-range communication, similar to ham radios, operates on EU868, an open frequency space. Range and bandwidth are inversely related, so we trade range for low transfer rates. This is sufficient for small data packets, but not for full audio transfer.\nLLM\nLarge Language Models gained popularity with ChatGPT and other similar models. Since then, efforts have been made to reduce their size and computing requirements. As a result, some models can now be run locally and offline.\nSciFi\nScience fiction writers often seek out new scientific and technical developments to prognosticate freely the techno-social changes that will shock the readers’ sense of what is culturally appropriate and expand their consciousness.\nSDR\nSoftware Defined Radio (SDR) is a programmable radio receiver for various frequencies. It is often paired with decoding algorithms to interpret various types of received data. The connected antenna determines the reception pattern.\nGQRX\nGQRX is an open source software for the software-defined radio.\nGQRX Software\n\nNesdr smaRT v5\nThis is the SDR we use, which can be controlled via USB and interfaces well with GQRX. It supports frequencies ranging from 100kHz to 1.75GHz, including many ham radio frequencies, remotes, phones, walkie-talkies, airplanes, police radios, and our LoRa mesh.\nInfrastructure\nInfrastructure refers to the physical and organizational structures and facilities required for the operation of a society or enterprise, such as buildings, roads, and power supplies. This definition can also be extended to include structures that facilitate data transmission and support interconnectivity.\nRadio waves\nRadio waves are a type of electromagnetic radiation that can carry information. They use the longest wavelengths in the electromagnetic spectrum, typically with frequencies of 300GHz or lower. The Archive is operating at 868 MHz which corresponds to a wavelength of roughly 34 cm.\nLilygo T3S3\nESP32-S3 LoRa SX1280 2.4G development board. Contains an ESP32 chip, WIFI, Bluetooth and a LoRa module. Can be connected via serial, Bluetooth or network. Is supported by meshtastic.\nCharacter building\nWe used structured ChatGPT dialogue and local Stable Diffusion for the characters that inhabit our future. Ask the archive for more info about them.\nPrivateGPT\nPrivateGPT is a set of libraries based on llama-index that allow local and offline inference using the computer‘s graphics card. PrivateGPT is particularly good at incorporating local documents. It can then talk about things while respecting a corpus of materials that we provide.\nTranshumanism\nBroadly, the idea that human beings can achieve their next evolutionary step, Human 2.0, through technological advances. Opinions differ as to how this post-human state will be achieved, either through genetic engineering, reverse aging or other technological advances. In our view, it is inspired by Social Darwinism.\nPerception of Infrastructure\nAt its core, infrastructure is an evasive structure. Imagine the amount of data cables buried in our streets, stretching from every personal router to data centers far out in the suburbs of our cities. None of this actual “structure“ is meant to be seen or interacted with until it fails…\nNetwork interface\nWe consider any device that has both user interactivity and Internet/network access to be a network interface.\nEco-Terrorism\nEcotage refers to infrastructure sabotage with ecological goals, while eco-terrorism is even more militant and will use militant strategies with the specific aim of creating terror as a social deterrent.\nPrepping\nPrepping is the act of preparing for the time after the catastrophe, resulting from the belief that current social models will collapse in an apocalyptic manner. Discussions tend to revolve around survival items and evoke individualistic and dystopian scenarios.\nInfrastructure inversion\n“rather than setting out to describe and document all parts of the system that make a footprint possible, the analysis focuses upon a selection of localized sites or issues as suggestive parts of a broader system that is imperceptible in its entirety” (Parks 2009)\nNeo-Religion\nThe Internet, as a network of networks, is such a multifaceted term that it has room for spiritual feelings in the interaction with the network. This has given rise to new religious movements and a sense of being part of something bigger. Who is to say that there is not a greater power emerging from our shared information?\nNeo-Luddism\nNeo-Luddism is a leaderless movement of unaffiliated groups who resist modern technology by passively refraining from using technology, harming those who produce environmentally harmful technology, or sabotaging that technology.\nSub-sea-cables\nCables are often referred to as the backbone of the Internet. Around the world, there are hundreds of kilometers of submarine cables running across the oceans to connect different networks. They are heavy, expensive and buried deep in the sea. Chances are you have never seen one, yet you rely on them every day to deliver information and content.\nOptical fiber cable\nFiber optic cables were developed in the 1980s. The first transatlantic telephone cable to use optical fiber was TAT-8, which went into service in 1988. A fiber optic cable consists of several pairs of fibers. Each pair has one fiber in each direction.\nCopper cable\nCopper is a rare metal and its use contributes to global neo-colonial power structures resulting in a multitude of exploitative practices.\nFor long-distance information transfer, it is considered inferior to Glass fiber cables, due to material expense and inferior weight-to-transfer speed ratio.\nCollapsology\nCollapsology is based on the idea that humans are having a sustained and negative impact on their environment and promotes the concept of an environmental emergency, particularly in relation to global warming and the loss of biodiversity. One potential effect of a collapse is the loss of networks.\nPosthumanism\nIs concerned with the “ongoing deconstruction of humanism” and its premises: humanism’s anthropocentrism, essentialism and speciesism. It is informed by post-anthropocentric ethics, politics, and ecology, and looks toward notions of embodiment and material entanglement between humans and a “more-than-human” world. It emphasizes becoming over being.\n\n"},{"url":"https://aron.petau.net/de/project/airaspi-build-log/","title":"Übersetzung: AIRASPI Build Log","body":"AI-Raspi Build Log\nThis should document the rough steps to recreate airaspi as I go along.\nRough Idea: Build an edge device with image recognition and object detection capabilites.\nIt should be realtime, aiming for 30fps at 720p.\nPortability and usage at installations is a priority, so it has to function without active internet connection and be as small as possible.\nIt would be a real Edge Device, with no computation happening in the cloud.\nInspo from: pose2art\nHardware\n\nRaspberry Pi 5\nRaspberry Pi Camera Module v1.3\nRaspberry Pi GlobalShutter Camera\n2x CSI FPC Cable (needs one compact side to fit pi 5)\nPineberry AI Hat (m.2 E key)\nCoral Dual Edge TPU (m.2 E key)\nRaspi Official 5A Power Supply\nRaspi active cooler\n\nSetup\nMost important sources used\ncoral.ai\nJeff Geerling\nFrigate NVR\nRaspberry Pi OS\nI used the Raspberry Pi Imager to flash the latest Raspberry Pi OS Lite to a SD Card.\nNeeds to be Debian Bookworm.\nNeeds to be the full arm64 image (with desktop), otherwise you will get into camera driver hell.\n{: .notice}\nSettings applied:\n\nused the default arm64 image (with desktop)\nenable custom settings:\nenable ssh\nset wifi country\nset wifi ssid and password\nset locale\nset hostname: airaspi\n\nupdate\nThis is always good practice on a fresh install.

What if cars would could be used as public spaces?\nBy installing a public USB socket and a public wifi hotspot, on my car, I want to start exploring the potential of cars as public spaces and energy storage solutions.\nWithin this artistic experiment, I will continuously track the geolocation and energy input/output of my solar equipped car and make the data publicly available. I will also track the amount of energy that is not used by the car and could be used by the public. Taking steps towards optimal usage of existing electrical and other infrastructure is only possible by breaking conventional notions of public ownership and private property. This project is one step towards a more sustainable and equitable future.\nIntroduction\nWe all know by now that cars and individual traffic presents a major environmetal and societal problem all over the world. The last 70 something years of building car infrastructure are culminating in many areas in a dead end where the only thinkable solution is to build more roads and cars.\nTHis is obviously a larger problem than one project can tackle, but here is one outlook on how\nExperiment\nPreexisting data\nWith the data collected over the last year of using the car privately I can show with embarrasing accuracy how underutilized the system is and calculate an estimate of energy lost due to societal notions of private property.\nThe data will be an estimate, since the monitoring itself is dependent on solar energy and the internet connection is spotty at best when it is not supplied with electricity.\nMonitoring\nIn the Car, there is a Raspberry Pi 4 Microcomputer running a custom Operating Systen that monitors the following data:\n\nSolar Intake (W)\nBattery Level (V)\nGPS Location\nTotal Energy Produced (Wh)\nTotal Energy Consumed (Wh)\nSolar Energy Potential (Wh)\n\nThrough the router I can also track total Wifi usage and the number of connected devices.\nPublic Wifi\nFor the Project, I opened a router in the Car towards the Public, much alike to ahotspot you would find in a cafe. I use my own data plan on there, which I never max out anyways. The router is a Netgear M1 and has a 4G Modem built in. It is connected to the Raspberry Pi and is powered by the secondary car battery.\nPublic Energy: A USB Socket\nI plan on installing a USB Socket on the outside of the car, so people can charge their devices. The socket will be connected to the secondary car battery and will be powered by the solar panels. The socket will be installed in a way that it is not possible to drain the battery completely.\nCommunication\nNobody expects any help or public supplies from car owners.\nHow to communicate the possibility to the outside world?\nThe plan is to fabricate a vinyl sticker that will be applied to the car. The sticker will contain a QR Code that will lead to a website with the data and a short explanation of the project. Visual cues lead to the USB Socket and the Wifi Hotspot.\nIssues\nSpace / Scale\nObviously, the space on top of a car is quite limited and from a sustainability perspective, it would be better to have a larger solar array on a roof of a house. The point is not to advocate for a mandated solar install on cars, but to optimize and share preexisting infrastructure. The car is already there, it already has a battery and it already has solar panels. Looking at many Camper-Van builds, the amount of cars with already installed solar panels is quite large. The point is to make the most out of it.\nLegality\nGermany has laws in place holding the owner of a Internet Connection liable for the legality of the traffic that is going through it. This is a major issue for the project, as I do not want to be liable for the traffic that is going through my car. I am currently looking into ways to circumvent this issue.\nSurveillance / Privacy\nThe Car is equipped with a GPS Tracker and a Wifi Hotspot. This means that I can track the location of the car and the number of devices connected to the hotspot. I am not tracking any data that is going through the hotspot, but I could. As this project will generate public data, People using and maybe depending on the internet and electricity provided will be tracked by proxy. I am not sure how to deal with this issue yet.

Going without emails is unimaginable in today's world, yet most providers are the familiar few from the silicon valley. And really, who wants their entire decentralized, federated, peer-to-peer network to be controlled by a schmuck from the silicon valley? Mails used to be more than that and they can still be.\nArguably, the world of messanging has gotten quite complex since emails popped up and there are more anti-spam AI tools that I would care to count. But the core of it is still the same and it is still a federated system.\nYet, also with Emails, Capitalism has held many victories, and today many emails that are sent from a provider that does not belong to the 5 or so big names are likely to be marked as spam. This is a problem that is not easily solved, but it is a problem that is worth solving.\nAnother issue with emails is security, as it is somehow collectively agreed upon that emails are a valid way to communicate business informations, while Whatsapp and Signal are not. These, at least when talking about messaging services with end-to-end encryption, are likely to be way more secure than emails.\nThe story\nSo it came to pass, that I, as the only one in the family interested in operating it, \"inherited\" the family domain petau.net. All of our emails run through this service, that was previously managed by a web developer that was not interested in the domjobain anymore.\nWith lots of really secure Mail Providers like Protonmail or Tutanota, I went on a research spree, as to how I would like to manage my own service. Soon noticing that secure emails virtually always come with a price or with lacking interoperability with clients like Thunderbird or Outlook, I decided to go for migadu, a swiss provider that offers a good balance between security and usability. They also offer a student tier, which is a big plus.\nWhile self-hosting seems like a great idea from a privacy perspective, it is also quite risky for a service that is usually the only way for any service to recover your password or your online identity.\nMigadu it was then, and in the last three months of basically set it and forget it, i am proud to at least have a decently granular control over my emails and can consciously reflect on the server location of The skeleton service service that enables virtually my entire online existence.\nI certainly crave more open protocols in my life and am also findable on Mastodon, a microblogging network around the ActivityPub Protocol.\n"},{"url":"https://aron.petau.net/de/project/lusatia/","title":"Übersetzung: Lusatia - an immersion in (De)Fences","body":"\n\nOn an Excursion to Lusatia, a project with the Working Title (De)Fences was born.\nHere are the current materials.\n\nTODO: upload unity project\n"},{"url":"https://aron.petau.net/de/project/autoimmunitaet/","title":"Autoimmunitaet","body":"How do we design our Commute?\nIn the context of the Design and Computation Studio Course Milli Keil, Marla Gaiser and me developed a concept for a playful critique of the traffic decisions we take and the idols we embrace.\nIt should open up questions of whether the generations to come should still grow up playing on traffic carpets that are mostly grey and whether the Letzte Generation, a political climate activist group in Germany receives enough recognition for their acts.\nA call for solidarity.\n\n{: .center}\nThe scan results\n \nThe Action Figure, ready for printing\n \nAutoimmunitaet\nAutoimmunity is a term for defects, that are produced by a dysfunctional self-tolerance of a system.\nThis dysfunction causes the immune system to stop accepting certain parts of itself and build antibodies instead.\nAn invitation for a speculative playful interaction.\n\n\n\n\n\n\nThe Process\nThe figurines are 3D Scans of ourselves, in various typical poses of the Letzte Generation.\nWe used photogrammetry to create the scans, which is a technique that uses a lot of photos of an object to create a 3D model of it.\nWe used the app Polycam to create the scans using IPads and their inbuilt Lidar scanners.\n"},{"url":"https://aron.petau.net/de/project/dreams-of-cars/","title":"Übersetzung: Dreams of Cars","body":"Photography\nIn the context of the course \"Fotografie Elementar\" with Sebastian Herold I developed a small concept of urban intervention.\nThe results were exhibited at the UdK Rundgang 2023 and are also visible here.\n\nDreams of Cars\nThese are not just cars.\nThey are Sport Utility Vehicles.\nWhat might they have had as hopes and dreams on the production line?\nDo they dream of drifting in dusty deserts?\nClimbing steep rocky canyon roads?\nSliding down sun-drenched dunes?\nDiscovering remote pathways in natural grasslands?\nNevertheless, they did end up in the parking spots here in Berlin.\nWhat drove them here?\n\n\n\n\n\n\n\n"},{"url":"https://aron.petau.net/de/project/stable-dreamfusion/","title":"Übersetzung: Stable Dreamfusion","body":"Stable Dreamfusion\n \nSources\nI forked a really popular implementation that reverse engineered the Google Dreamfusion algorithm.

A bloomery furnace was used to create iron. Making iron requires iron ore and heat under the exclusion of oxygen. It is a highly fragile process that takes an incredible amount of work. The designs and methods vary a lot and were very adapted to the region and local conditions, unlike the much later, more industrialized process using blast furnaces.\nTo this day it is quite unclear how prehistoric people managed to get the amount and quality of iron we know they had.\nThe furnaces that were built were often clay structures and are not preserved. Archeologists often find the leftover burned ore and minerals, giving us some indication of the structure and composition of the ancient furnaces.\nThe group around the ISD takes up a practical archeological approach and we try to recreate the ancient methods with the added capability of maybe sticking temperature probes or electric blowers. Each year we meet up in a different European city and try to adapt to the local conditions, often with local ore and local coal. It is a place where different areas of expertise come together to educate each other while sitting together through the intense day- and night shifts to feed the furnaces.\nSince being a kid, I started building my own furnaces and read up on the process so I could participate.\nTechnology gets a different tint when one is involved in such a process: Even the lights we put up to work through the evening are technically cheating. We use thermometers, meticulously weigh and track the inbound coal and ore, and have many modern amenities around. Yet - with our much more advanced technology, our results are often inferior in quantity and quality in comparison with historical findings. Without modern scales, iron-age people were more accurate and consistent than we are.\nAfter some uncertainty about whether it would take place in 2021 again after it was canceled in 2020, a small group met up in Ulft, Netherlands.\nThis year in Ulft, another group made local coal, so that the entire process was even lengthier, and visitors came from all over to learn about making iron the pre-historic way.\nBelow I captured most of the process in some time-lapses.\nThe Process\n\n\nHere you can see a timelapse of me building a version of an Iron Furnace\nAs you can see, we are using some quite modern materials, such as bricks, this is due to the time constraints of the ISD.\nMaking an oven completely from scratch is a much more lengthy process requiring drying periods in between building.\nAfter, the furnace is dried and heated up\nOver the course of the process, more than 100 kgs of coal and around 20 kgs of ore are used to create a final piece of iron of 200 - 500g, just enough for a single knife.\nWith all the modern amenities and conveniences available to us, a single run still takes more than 3 people working over 72 hours, not accounting for the coal-making or mining and relocating the iron ore.\nSome more impressions from the ISD\n\n\n\n \n \n \n \n \n \n \n \n \n \n a loaded bloomery furnace\n \n \n \n \n \n \n \n \n \n \n \n The ISD from above\n \n \n \n \n \n \n \n \n \n \n \n glowing iron\n \n \n \n \n \n \n \n \n \n \n \n a furnace burning\n \n \n \n \n \n \n \n \n \n \n \n Compacting the resulting iron\n \n \n \n \n \n \n \n \n \n \n \n a heat camera image of the furnace\n \n \n \n \n \n \n \n \n \n \n \n A cross-section illustrating the temperatures reached\n \n \n \n \n\nFor me, it is very hard to define what technology encompasses.

With the struggles our university had transitioning to online teaching, I selected a guided topic, although my initial dream was to start writing about my proposed plan for automated plastic recycling. You can read more about that here:\n\nI chose a project that wanted to examine the possibilities of a novel smart hearing protection device specifically designed for auditory hypersensitivity, which is often, but not always, and not exclusively a phenomenon visible in people with an autism spectrum disorder.\nA common reaction to this elevated sensitivity is stress and avoidance behavior, often leading to very awkward social situations and impairing the ability to take part in social situations.\nSchools are one such social situation and we all know the stress a noisy classroom can produce. Concentration is gone, and education, as well as essential skills like language reproduction, suffer.\nThere is lots of prior research on these fields, and there is some evidence that sensory information in people on the Autism spectrum is processed differently than in a neurotypical brain. It seems that a certain adaptability, needed to overcome noise issues and bridge asynchrony between auditory and visual sensory input, is reduced in some people on the Autism Spectrum.\nIn essence, my experiment was responsible for looking at neurotypical people and measuring any effect on language perception produced by varying the delay between auditory and visual input, as well as the loudness.\nHere, I had the possibility to conduct an entire reaction-time-based experiment with over 70 participants and went through all the struggles that come with proper science.\nI did extensive literature research, coded the experiment, and learned a lot about the reasons nobody really ever does reaction time-based studies like this via a common internet browser.\nIt was an almost 9 months long learning experience full of doing things I had never done before.\nI learned and got to love writing in Latex, had to learn JavaScript for the efficient serving of the stimuli, and R for the statistical analysis. I also got to brush up on my data visualization skills in Python and made some pretty graphs of the results.\nThe experiment is still working and online if you want to have a look at it. Be mindful though that measuring reaction speed every millisecond is important, which is why it makes heavy use of your browser cache and has been known to crash and defeat some not-so-tough computers.\n\n Try out the experiment yourself\n\nEven with writing alone I had extensive helpful feedback from my supervisors and learned a lot about scientific processes and associated considerations.\nThere was always the next unsolvable problem.

I am incredibly thankful for this methodology of approaching complex philosophical works, often complete books with supplicant essays surrounding the course topic. In my opinion, nearly all of the value created during these seminars is contained within the live discussions fed by reading materials and little opinion pieces in the form of forum comments. That's why I decided to share here a selection of these weekly commentaries and the sources they are based upon. They are often unrefined and informal, but they indicate the centerpiece of the seminars and demonstrate many thought processes that happened within me during these sessions. Although I took only a small selection, in sum they are a substantial read. Feel free to just skip through and read what catches your interest.\nForum entries from the Seminar: Critical Epistemologies\nOn Anderson: Institutions\n\n\t\n\t\tAnmerkung\n\tSource Text: Epistemic Justice as a Virtue of Social Institutions\nElizabeth Anderson (2012) Epistemic Justice as a Virtue of Social Institutions, Social Epistemology, 26:2, 163-173,\nDOI: 10.1080/02691728.2011.652211 Publication\n\n\nThe text by Anderson helped shed light on a few issues I stumbled over with Frickers Account. On top of the various issues I and seemingly others have with her virtue-based approach, I think a utilitarian angle is worth considering. That would be: okay, I accept that people can help fight injustice by realising their privilege, showing restraint, silencing themselves, and adopting the benevolent listening approach. I think that is a practical, virtuous, and realistic endeavour.\nBut is it the effective path to alleviating structural injustice? I think not, and initially, that is a major reason I discarded Fricker’s approach, although I saw merit. I have similar concerns to Anderson in the scalability of virtues. Virtuous behavior might help my personal well-being, it gives me normative elevation and might even further the quality of relationships I have. But is it applicable to society, is it enough to counteract structural injustice?\nWell, maybe, assuming that:\n\nEveryone realizes their privilege,\nEveryone concludes that justice is the right goal,\nUpon deciding to adopt a virtuous stance, everyone at least moderately succeeds in practicing what they preach.\n\nI think, for society, the same society that came up with patriarchy in the first place, external pressure, some measure independent of the convictedness of the subjects is needed.\nAnderson made the powerful point of: “Anything that works, goes”, which took me some time to appreciate. I am always angry when I get told to keep my shower to a minimum or stop using plastic straws when I know exactly that my using less water is nothing compared to the institutionalized practice of Coca-Cola putting water into bottles. I feel like it is unjustified to ask me to save water while others triple their output, for performance.\nThe same thing applies to Epistemic injustices. It strikes me how much energy it costs to keep up virtuous behavior individually and how little effect there is to show for it. I do not believe in “trickling up” where institutions will eventually adopt individual practices.\nIs Fricker thereby less right in her point? No, it adds up, as an entire population showering shorter adds up to lots of water saved.\nAnderson also points out how locally innocent biases can create injustice on a “macro” scale. Another indicator for me is that local virtue is not the sole solution, as it can still feed and sustain a system enforcing epistemic injustice.\nI still have doubts about what to do now with my ideas, on how the world looks that I want. I lack the imagination of seeing a world that is epistemically just, and it is hard to strive for something one cannot even imagine. The system is inherently leaning toward inequality, if I try to balance something on a needle, it will only go well so long, before small imbalances create chain reactions and the object should be called unstable. Should we even succeed in “resetting” society, creating equal participation for each subject, how will it remain just? Is Justice always a conjunct of Equality? Are there ways to achieve real Justice without needing equality?\n\n\t\n\t\tAnmerkung\n\tcreated by Aron Petau on Tuesday 14. July 2020, 17:45\n\n\nOn Medina, the informant and the inquirer\n\n\t\n\t\tAnmerkung\n\tSource Text: Dr. José Medina (2012) Hermeneutical Injustice and Polyphonic Contextualism: Social Silences and Shared Hermeneutical Responsibilities, Social Epistemology, 26:2, 201-220, DOI: 10.1080/02691728.2011.652214\nPublication\n\n\nMy biggest takeaway here was that, as I tried to hint at in an earlier comment,\nWhenever we talk about justice, this necessarily refers to a relational concept, where everybody has a double role to ensure successful communication. Medina calls these the inquirer and the informant. So, every individual has to make sure to act to her capacity as an epistemologically sound knowledge-acquiring agent (the inquirer). This would involve knowing when and how to falsify/qualify statements, making inferences about the theory of mind, and generally comparing different statements. The other role is the informant, where the individual should have the capacity to function as an object in an inquiry by another.\nVery roughly this can, I think, be compared to any good communication model, where there are a listener and a speaker, and both have to function. What was new here, or at least came out more clear is that it not only depends on the capacity of both of these roles on the subject, but it is also directly dependent on the “other”, the agent opposite of the subject. We may call this other society later but it helps me to visualize the other as an individual nonetheless. Where the analogy to communication now fails, in my opinion, is this cross-dependence, where an agent does not fully determine her capacity to act both as an inquirer and as an informant, it is co-determined by the “other”. So, if I, as an “other”, listen to someone's statements, and I fail or refuse to understand the epistemic content of the message, I am not only impairing my epistemic agency, but I also hurt the epistemic agency of the subject. Maybe obvious to most, but this thought struck me as being exactly the point of leverage for dysfunctionalities in power relations.\nAlso argued convincingly in the paper was that these are distinct and independent agencies, which can be impairing an individual separately.\nOverall, the Medina text was incredibly helpful after the somewhat confusing Fricker text that felt incomplete and left a lot of questions for me. The medina text picked up all my initial doubts, that I couldn't properly formulate, and many more, while still holding to the general framework of Fricker.\nAlthough I was not convinced by the Fricker Text, I tend to think the strategy:\n\"When in doubt, give the subject full epistemic credibility\"\nIs a good strategy that might alleviate a lot of issues regarding functions of power, and hierarchy, but also further, it might be a good counter for things as our confirmation bias, expectation bias and many individual errors that we could minimize by constantly exposing ourselves to falsifiability through others (voluntarily). Sounds like science applied to agency to me.\n\n\t\n\t\tAnmerkung\n\tcreated by Aron Petau on Thursday 09. July 2020, 11:25\n\n\nOn Jaggar: Norms, Outlaw Emotions, and the Ideal Society\n\n\t\n\t\tAnmerkung\n\tSource Text: Alison M. Jaggar (1989) Love and knowledge: Emotion in feminist epistemology, Inquiry, 32:2, 151-176, DOI: 10.1080/00201748908602185\nPublication\n\n\nI found Jaggar to be a very wholesome read, it was the perfect amount of grounded argumentative structure and felt very connected as a whole. This was, together with the ideas from Lugones the best and most fruitful paper for me.\nOn outlaw emotions:\nFirst, I hate the term, I think it’s placative and fails to frame the (actually nice) idea behind it.\nOutlaw Emotions are all those emotions incompatible with the dominant norms. That’s a huge field to cover, among feminist emotions they would also encompass emotions that are irrational or “faulty”. So, Jaggar does the term Justice by saying, some, but not all Outlaw Emotions are Feminist emotions. To make this evident, just think of a murderer's joy for killing, it is of no feminist interest to dissect, yet it is against dominant values. So, experiencing Outlaw emotions is a (probably) necessary, but not sufficient condition for feminism. The incompatible emotion serves to create discourse and change.\nJaggar convincingly shows how emotions have a direct influence on beliefs and can validly constitute evidence, while simultaneously validly influencing values in a similar manner.\nWhen we talk about dominant/alternative norms, we already endorse hierarchy in society. We acknowledge its existence, simply by identifying the dominant norm. I am not quite sure what exactly Jaggar proposes we should do with the hierarchy structures in society. Explicitly I can read: Subcultures rejecting dominant norms should be formed, to create counterbalances and a somewhat fair discourse over the topic.\n“How can we determine which outlaw emotions are to be endorsed or encouraged and which rejected? In what sense can we say that some emotional responses are more appropriate than others? What reason is there for supposing that certain alternative perceptions of the world, perceptions informed by outlaw emotions, are to be preferred to perceptions informed by conventional emotions? Here I can indicate only the general direction of an answer, whose full elaboration must await another occasion. I suggest that emotions are appropriate if they are characteristic of a society in which all Human Life (and perhaps some nonhuman life, too) thrive, or if they are conducive to establishing such a society.”\nTo me this passage sounds sketchy at best, there is no indication of how to successfully separate appropriate from inappropriate emotions. Roughly, I read this part as: emotions are warranted iff they increase the balance of power. (equivalent to minimizing the height of the hierarchy) I would love to get to read this “other occasion” because it seems indefensible to me to formulate a norm that states: Accept only emotions which eliminate/diminish norms.\nThe idea roughly resembles Rawls's Minimax Principle, where a policy should be implemented iff the benefit for the most disadvantaged is highest.\nAnother thing I found helpful is her reformulation of what norms do:\n“Dominant Norms tend to serve dominant interests”\ntil here nothing new, this is a tautology for me, I understand norms as identical to dominant interests, that’s literally what norms are.\nIs an alternative, suppressed norm even thinkable? Isn't it inherent in a norm that it be the dominant one?\nBut then, after that: \"Whatever our color / gender / class / sexual orientation, we are likely to adopt the dominant value of racist, classist, homophobe, misogynistic white men.\"\nThis was rather helpful to me, as it reframes the “act” of oppression as the “likelihood of value distribution” being skewed in your favor, making everybody’s values more likely to be similar to yours. This nicely illustrates how a system can be hierarchical and oppressive, without anybody actively, intentionally “acting oppressive”, while still perpetuating oppression. I'm\nnot saying everybody is acting unintentionally oppressive, but it is always hard to imagine for me to picture \"White Men\" forming a group and collectively deciding on who to hate this coming season, Conceptually separating \"being oppressed\" and \"oppressing\" into phenomena\nwithout necessary inherent causal relation makes sense to me here.\n\n\t\n\t\tAnmerkung\n\tcreated by Aron Petau on Tuesday 23.

Se défendre: une philosophie de la violence. Zones, 2017.\nPublication (Not yet translated to English)\n\n\nFrom the seventh chapter in Dorlins \"Self-Defense\", I found the idea that safe spaces are actually prone to be counterproductive very strong.\nI think the discussion around whether safe spaces are an effective tool that is appropriate on top is a rather current and ongoing one.\nIn so many other words, Dorlin here opens up the idea that the creation of a safe space always implies a hostile \"outside\" or other space.\nFurther, Dorling sees as problematic that safe spaces will often experience problematic situations when trying to self-govern. The line of thought here is that safe spaces often explicitly reject the authority of traditional state bodies, since those exactly are identified as the oppressive force. This is problematic because then the community inside the safe space has to recreate social norms from scratch and qua definition of a safe space end up being much more restrictive and monitoring, tapping also into potentially extreme measurements for \"enforcing\" safety.\nDorlin notes that by doing this, societal oppressive norms can end up becoming reproduced through the very instance created to shelter from it.\nI think this opens up 2 points worth discussing:\nAre there limits to the self-governance of leftist groups? How can self-governance be made possible without recreating some hierarchy or other?\nDoes this ignore that safe spaces can sometimes be essential for survival? According to Dorlin, the alternative seems to be to instead of building sheltered, isolated safe spaces, the fight has to occur in the public, transforming the entire space without the necessity for exclusive logic. How can we argue this? Could there be an oppressed position from whence any aggressive stance towards the public forbids itself? (I think there is!) For me this seems like putting the entire burden of transformational potential on the oppressed individual, enabling a position like: \"Well, the person did not object or introduce change, so the person implied consent.\"\nWill a public fight cause more harm being fought than it will save after introducing change? And who are we to calculate this beforehand?\n\n\t\n\t\tAnmerkung\n\tcreated by Aron Petau on Sunday 05.

Reading Judith Butler and Elsa Dorlin\nOn Dorlin\n\n\t\n\t\tAnmerkung\n\tSource Text: Dorlin, Elsa. Se défendre: une philosophie de la violence. Zones, 2017.\nPublication (Not yet translated to English)\n\n\nFrom the seventh chapter in Dorlins \"Self-Defense\", I found the idea that safe spaces are actually prone to be counterproductive very strong.\nI think the discussion around whether safe spaces are an effective tool that is appropriate on top is a rather current and ongoing one.\nIn so many other words, Dorlin here opens up the idea that the creation of a safe space always implies a hostile \"outside\" or other space.\nFurther, Dorling sees as problematic that safe spaces will often experience problematic situations when trying to self-govern. The line of thought here is that safe spaces often explicitly reject the authority of traditional state bodies, since those exactly are identified as the oppressive force. This is problematic because then the community inside the safe space has to recreate social norms from scratch and qua definition of a safe space end up being much more restrictive and monitoring, tapping also into potentially extreme measurements for \"enforcing\" safety.\nDorlin notes that by doing this, societal oppressive norms can end up becoming reproduced through the very instance created to shelter from it.\nI think this opens up 2 points worth discussing:\nAre there limits to the self-governance of leftist groups? How can self-governance be made possible without recreating some hierarchy or other?\nDoes this ignore that safe spaces can sometimes be essential for survival? According to Dorlin, the alternative seems to be to instead of building sheltered, isolated safe spaces, the fight has to occur in the public, transforming the entire space without the necessity for exclusive logic. How can we argue this? Could there be an oppressed position from whence any aggressive stance towards the public forbids itself? (I think there is!) For me this seems like putting the entire burden of transformational potential on the oppressed individual, enabling a position like: \"Well, the person did not object or introduce change, so the person implied consent.\"\nWill a public fight cause more harm being fought than it will save after introducing change? And who are we to calculate this beforehand?\n\n\t\n\t\tAnmerkung\n\tcreated by Aron Petau on Sunday 05.

Sadly, we used beta functionality from the older \"Google Assistant\" Framework, which got rebranded months after by Google into \"Actions on Google\" and changed core functionality requiring extensive migration that neither Chris, my partner in this project, nor I found time to do.\nNevertheless, the whole Chatbot functioned as a meditation player and was able to graph and store recorded sentiments over time for each user.\nAttached below you can also find our final report with details on the programming and thought process.\n\n Read the full report\n\n\n Look at the Project on GitHub\n\n\n\t\n\t\tAnmerkung\n\tAfter this being my first dip into using the Google Framework for the creation of a speech assistant and encountering many problems along the way that partly found their way also into the final report, now I managed to utilize these explorations and am currently working to create Ällei, another chatbot with a different focus, which is not realized within Actions on google, but will rather be getting its own react app on a website.\n\n\n"},{"url":"https://aron.petau.net/de/project/critical-epistemologies/","title":"Übersetzung: Critical Epistemology","body":"Forum entries from the Seminar: Critical Epistemologies\nOn Anderson: Institutions\n\n\t\n\t\tAnmerkung\n\tSource Text: Epistemic Justice as a Virtue of Social Institutions\nElizabeth Anderson (2012) Epistemic Justice as a Virtue of Social Institutions, Social Epistemology, 26:2, 163-173,\nDOI: 10.1080/02691728.2011.652211 Publication\n\n\nThe text by Anderson helped shed light on a few issues I stumbled over with Frickers Account. On top of the various issues I and seemingly others have with her virtue-based approach, I think a utilitarian angle is worth considering. That would be: okay, I accept that people can help fight injustice by realising their privilege, showing restraint, silencing themselves, and adopting the benevolent listening approach. I think that is a practical, virtuous, and realistic endeavour.\nBut is it the effective path to alleviating structural injustice? I think not, and initially, that is a major reason I discarded Fricker’s approach, although I saw merit. I have similar concerns to Anderson in the scalability of virtues. Virtuous behavior might help my personal well-being, it gives me normative elevation and might even further the quality of relationships I have. But is it applicable to society, is it enough to counteract structural injustice?\nWell, maybe, assuming that:\n\nEveryone realizes their privilege,\nEveryone concludes that justice is the right goal,\nUpon deciding to adopt a virtuous stance, everyone at least moderately succeeds in practicing what they preach.\n\nI think, for society, the same society that came up with patriarchy in the first place, external pressure, some measure independent of the convictedness of the subjects is needed.\nAnderson made the powerful point of: “Anything that works, goes”, which took me some time to appreciate. I am always angry when I get told to keep my shower to a minimum or stop using plastic straws when I know exactly that my using less water is nothing compared to the institutionalized practice of Coca-Cola putting water into bottles. I feel like it is unjustified to ask me to save water while others triple their output, for performance.\nThe same thing applies to Epistemic injustices. It strikes me how much energy it costs to keep up virtuous behavior individually and how little effect there is to show for it. I do not believe in “trickling up” where institutions will eventually adopt individual practices.\nIs Fricker thereby less right in her point? No, it adds up, as an entire population showering shorter adds up to lots of water saved.\nAnderson also points out how locally innocent biases can create injustice on a “macro” scale. Another indicator for me is that local virtue is not the sole solution, as it can still feed and sustain a system enforcing epistemic injustice.\nI still have doubts about what to do now with my ideas, on how the world looks that I want. I lack the imagination of seeing a world that is epistemically just, and it is hard to strive for something one cannot even imagine. The system is inherently leaning toward inequality, if I try to balance something on a needle, it will only go well so long, before small imbalances create chain reactions and the object should be called unstable. Should we even succeed in “resetting” society, creating equal participation for each subject, how will it remain just? Is Justice always a conjunct of Equality? Are there ways to achieve real Justice without needing equality?\n\n\t\n\t\tAnmerkung\n\tcreated by Aron Petau on Tuesday 14. July 2020, 17:45\n\n\nOn Medina, the informant and the inquirer\n\n\t\n\t\tAnmerkung\n\tSource Text: Dr. José Medina (2012) Hermeneutical Injustice and Polyphonic Contextualism: Social Silences and Shared Hermeneutical Responsibilities, Social Epistemology, 26:2, 201-220, DOI: 10.1080/02691728.2011.652214\nPublication\n\n\nMy biggest takeaway here was that, as I tried to hint at in an earlier comment,\nWhenever we talk about justice, this necessarily refers to a relational concept, where everybody has a double role to ensure successful communication. Medina calls these the inquirer and the informant. So, every individual has to make sure to act to her capacity as an epistemologically sound knowledge-acquiring agent (the inquirer). This would involve knowing when and how to falsify/qualify statements, making inferences about the theory of mind, and generally comparing different statements. The other role is the informant, where the individual should have the capacity to function as an object in an inquiry by another.\nVery roughly this can, I think, be compared to any good communication model, where there are a listener and a speaker, and both have to function. What was new here, or at least came out more clear is that it not only depends on the capacity of both of these roles on the subject, but it is also directly dependent on the “other”, the agent opposite of the subject. We may call this other society later but it helps me to visualize the other as an individual nonetheless. Where the analogy to communication now fails, in my opinion, is this cross-dependence, where an agent does not fully determine her capacity to act both as an inquirer and as an informant, it is co-determined by the “other”. So, if I, as an “other”, listen to someone's statements, and I fail or refuse to understand the epistemic content of the message, I am not only impairing my epistemic agency, but I also hurt the epistemic agency of the subject. Maybe obvious to most, but this thought struck me as being exactly the point of leverage for dysfunctionalities in power relations.\nAlso argued convincingly in the paper was that these are distinct and independent agencies, which can be impairing an individual separately.\nOverall, the Medina text was incredibly helpful after the somewhat confusing Fricker text that felt incomplete and left a lot of questions for me. The medina text picked up all my initial doubts, that I couldn't properly formulate, and many more, while still holding to the general framework of Fricker.\nAlthough I was not convinced by the Fricker Text, I tend to think the strategy:\n\"When in doubt, give the subject full epistemic credibility\"\nIs a good strategy that might alleviate a lot of issues regarding functions of power, and hierarchy, but also further, it might be a good counter for things as our confirmation bias, expectation bias and many individual errors that we could minimize by constantly exposing ourselves to falsifiability through others (voluntarily). Sounds like science applied to agency to me.\n\n\t\n\t\tAnmerkung\n\tcreated by Aron Petau on Thursday 09.

Jaggar (1989) Love and knowledge: Emotion in feminist epistemology, Inquiry, 32:2, 151-176, DOI: 10.1080/00201748908602185\nPublication\n\n\nI found Jaggar to be a very wholesome read, it was the perfect amount of grounded argumentative structure and felt very connected as a whole. This was, together with the ideas from Lugones the best and most fruitful paper for me.\nOn outlaw emotions:\nFirst, I hate the term, I think it’s placative and fails to frame the (actually nice) idea behind it.\nOutlaw Emotions are all those emotions incompatible with the dominant norms. That’s a huge field to cover, among feminist emotions they would also encompass emotions that are irrational or “faulty”. So, Jaggar does the term Justice by saying, some, but not all Outlaw Emotions are Feminist emotions. To make this evident, just think of a murderer's joy for killing, it is of no feminist interest to dissect, yet it is against dominant values. So, experiencing Outlaw emotions is a (probably) necessary, but not sufficient condition for feminism. The incompatible emotion serves to create discourse and change.\nJaggar convincingly shows how emotions have a direct influence on beliefs and can validly constitute evidence, while simultaneously validly influencing values in a similar manner.\nWhen we talk about dominant/alternative norms, we already endorse hierarchy in society. We acknowledge its existence, simply by identifying the dominant norm. I am not quite sure what exactly Jaggar proposes we should do with the hierarchy structures in society. Explicitly I can read: Subcultures rejecting dominant norms should be formed, to create counterbalances and a somewhat fair discourse over the topic.\n“How can we determine which outlaw emotions are to be endorsed or encouraged and which rejected? In what sense can we say that some emotional responses are more appropriate than others? What reason is there for supposing that certain alternative perceptions of the world, perceptions informed by outlaw emotions, are to be preferred to perceptions informed by conventional emotions? Here I can indicate only the general direction of an answer, whose full elaboration must await another occasion. I suggest that emotions are appropriate if they are characteristic of a society in which all Human Life (and perhaps some nonhuman life, too) thrive, or if they are conducive to establishing such a society.”\nTo me this passage sounds sketchy at best, there is no indication of how to successfully separate appropriate from inappropriate emotions. Roughly, I read this part as: emotions are warranted iff they increase the balance of power. (equivalent to minimizing the height of the hierarchy) I would love to get to read this “other occasion” because it seems indefensible to me to formulate a norm that states: Accept only emotions which eliminate/diminish norms.\nThe idea roughly resembles Rawls's Minimax Principle, where a policy should be implemented iff the benefit for the most disadvantaged is highest.\nAnother thing I found helpful is her reformulation of what norms do:\n“Dominant Norms tend to serve dominant interests”\ntil here nothing new, this is a tautology for me, I understand norms as identical to dominant interests, that’s literally what norms are.\nIs an alternative, suppressed norm even thinkable? Isn't it inherent in a norm that it be the dominant one?\nBut then, after that: \"Whatever our color / gender / class / sexual orientation, we are likely to adopt the dominant value of racist, classist, homophobe, misogynistic white men.\"\nThis was rather helpful to me, as it reframes the “act” of oppression as the “likelihood of value distribution” being skewed in your favor, making everybody’s values more likely to be similar to yours. This nicely illustrates how a system can be hierarchical and oppressive, without anybody actively, intentionally “acting oppressive”, while still perpetuating oppression. I'm\nnot saying everybody is acting unintentionally oppressive, but it is always hard to imagine for me to picture \"White Men\" forming a group and collectively deciding on who to hate this coming season, Conceptually separating \"being oppressed\" and \"oppressing\" into phenomena\nwithout necessary inherent causal relation makes sense to me here.\n\n\t\n\t\tAnmerkung\n\tcreated by Aron Petau on Tuesday 23.

Dies führt zu einer riesigen Industrie, insbesondere in Deutschland, die enorme Mengen an Neukunststoff verbraucht.\nWas kann man tun?\nWir können Produkte langlebiger gestalten, Recycling-Labels aufdrucken und nur funktionale Objekte drucken. Dennoch verhindert dies nicht die Nutzung von Neukunststoffen. Recycelter Filament ist oft doppelt so teuer bei schlechterer Qualität – kein Wunder, dass er kaum Verbreitung findet.\n\n\nDas Kernproblem ist die fehlende wirtschaftliche Machbarkeit eines echten Recyclings. Das exakte Identifizieren von Kunststoffarten ist extrem schwierig und noch ungelöst. Es gibt Bereitschaft zu recyceln, aber das System fehlt.\nDer Masterplan\nIch möchte Menschen motivieren, ihren Müll zu waschen und zu sortieren, die teuersten Schritte im Recyclingprozess. Selbst kleine Beiträge, wie meine Mutter, die Flaschendeckel sammelt, sind wertvoll.\nDies funktioniert nur in einem lokalen, dezentralen Umfeld. Existierende Recyclinganlagen können nicht 200 verschiedene Kunststoffarten trennen.\nMit sauberem, sortiertem Material – etwa Flaschendeckel (HDPE) oder fehlerhafte Drucke (PET-G) – starte ich bereits im Vorteil. Jetzt müssen die Teile noch in gleichmäßige Partikel zerkleinert werden.\nDer Shredder\nWir bauten den Precious Plastic Shredder!\n \nMit diesen Open-Source-Zeichnungen konnte ich meinen eigenen, sehr gefährlichen Kunststoff-Shredder zusammenbauen.\nDie Motorisierung übernahm ein alter Gartenschredder, der Motor und Verkabelung intakt hatte. Wir schnitten ihn auseinander und befestigten ihn am Shredder.\n\n\nNach Austausch der schwachen Kraftübertragungsschraube gegen einen Industrie-Kuppler waren wir startklar. Sicherheit bleibt ein Thema, ein richtiger Trichter ist in Arbeit.\nDer Filastruder\nDer Filastruder, entworfen von Tim Elmore, bietet eine kostengünstige Möglichkeit, Filament zu extrudieren.\nDie größten Herausforderungen: präzise Durchmesserkontrolle ±0,03 mm, sonst schwankt die Qualität.\nMotor presst Kunststoffpellets durch eine beheizte Schraube, am Ende wird durch die Düse extrudiert und der Durchmesser eingestellt. Links wickelt die Maschine das Filament auf eine Spule.\n\n\nDer Filastruder wird von einem Arduino gesteuert und ist hoch konfigurierbar. Ein Lasersensor misst den Filamentdurchmesser.\nMachine Learning für optimale Filamentqualität\nWichtige Variablen: Wickelgeschwindigkeit, Extrusionsgeschwindigkeit, Temperatur, Kühlung.\nDiese Variablen können in Echtzeit optimiert werden – ähnlich wie in kommerziellen Anlagen.\n\nAutomatisierung ist nicht nur ein Jobkiller, sondern kann Umweltprobleme lösen.\nDieses Projekt liegt mir sehr am Herzen und wird Teil meiner Masterarbeit sein.\nDie Umsetzung erfordert viele Skills, die ich im Design & Computation Programm lerne oder noch vertiefe.\n \n Reflow Filament \n \n \n Perpetual Plastic Project \n \n \n Precious Plastic Community \n \n \n Filamentive Statement zur Recycling-Herausforderung \n \n \n Open Source Filament-Durchmesser-Sensor von Tomas Sanladerer \n \n \n Re-Pet Shop \n\n"},{"url":"https://aron.petau.net/de/project/beacon/","title":"BEACON","body":"BEACON: Dezentralisierung des Stromnetzes in unzugänglichen und abgelegenen Regionen\nZugang zu Elektrizität ist ein grundlegendes Menschenrecht. Das mag zunächst übertrieben klingen, doch wenn man bedenkt, wie viele kleine Aufgaben der Strom uns indirekt abnimmt – Licht, Wäsche, Kochen, Kühlen, Heizen, Unterhaltung – wird schnell klar, wie viel Zeit und Aufwand ohne Elektrizität nötig wäre. Weltweit leben etwa eine Milliarde Menschen ohne Zugang zu Strom auf dem sogenannten Tier-2-Level.\nSDGS Ziel 7\n\nMenschen erkennen erst dann, wie viel Arbeit in alltäglichen Dingen steckt, wenn sie keinen Strom haben. Doch es geht dabei nicht nur um Bequemlichkeit – Elektrizität rettet Leben: Krankenhäuser, Telekommunikation, Kühlung von Medikamenten – all das hängt davon ab.\nWarum also sind immer noch so viele Menschen unterversorgt?\nDie Antwort: fehlende Rentabilität. Es wäre ein wohltätiges, aber kein profitables Projekt, jede Person auf der Welt zu versorgen. Doch was, wenn wir eine Struktur finden könnten, die wirtschaftlich tragfähig ist und sich gleichzeitig an schwierige Bedingungen (Wetter, Abgeschiedenheit, Höhenlage) sowie an kleinere Einkommen anpassen kann?\nStandort\nEnde 2018 verbrachte ich vier Monate im Norden Indiens – im Rahmen eines Forschungsprojekts mit dem IIT Kharagpur.\nDas Ziel: an einem der 17 von der UN definierten nachhaltigen Entwicklungsziele zu arbeiten – Elektrizität.\nWeltweit haben schätzungsweise eine Milliarde Menschen keinen oder nur unzureichenden Zugang zum Stromnetz.\nEinige davon leben hier – im Key-Kloster im Spiti-Tal, auf etwa 3500 Metern Höhe.\n\n \n\nDas ist Tashi Gang, ein Dorf nahe des Klosters. Es beherbergt rund 50 Menschen und ist nur drei bis vier Monate im Sommer über eine Straße erreichbar. Den Rest des Jahres sind die Bewohner auf Hubschrauber-Erste-Hilfe angewiesen – erreichbar nur über einen funktionierenden Mobilfunkturm.\n \nDas Projekt\nIn einer Umgebung, die auf Wasser- und Sonnenenergie angewiesen ist, mit über sechs Monaten Schnee, häufigen Schneestürmen und Temperaturen bis zu –35 °C, ist die Netzsicherung schwierig.\nUnser Ansatz war es, die im Westen etablierte Vorstellung von Elektrizität als homogenes, zentral erzeugtes Produkt zu hinterfragen und stattdessen die Möglichkeiten eines prädiktiven, sich selbst korrigierenden und dezentralen Netzes zu erforschen.\nAnstatt bei einem Sturm einen kompletten Blackout zu riskieren, könnten bei einer Priorisierung der Energieverwendung wichtige Funktionen – etwa Radiotürme oder Krankenhäuser – teilweise weiterbetrieben werden. Die Binarität von Strom / kein Strom würde durch ein System von Zuteilungen nach Bedarf und Zeitfenstern ersetzt.\nLangfristig war die Vision ein lokaler, prädiktiver Strommarkt, bei dem Menschen überschüssige Energie verkaufen können.\nZur Machbarkeitsprüfung führte ich psychologische Akzeptanzstudien durch und sammelte Daten zum lokalen Stromverbrauch. Anschließend simulierte ich einen typischen Strombedarfstag im Key-Kloster und in den umliegenden Dörfern und entwickelte Konzepte für kostengünstige Smart-Microgrid-Controller.\nDie hier in Deutschland verfügbaren Netzsteuerboxen kosten mehrere Hundert bis Tausend Euro – keine realistische Lösung für die Bevölkerung vor Ort. Stattdessen planten wir Raspberry Pi-basierte Systeme, vernetzt über Ethernet oder lokale Mesh-Netze.\nForschung\n\nDatenerhebung\nDurch den Besuch öffentlicher Schulen im Englischunterricht konnte ich mit Jugendlichen über den Stromzustand in ihren Haushalten sprechen und umfangreiche Daten erheben. Insgesamt nahmen 145 Teilnehmer aus über sechs Schulen in etwa vier Distrikten teil – alle im indischen Himalaya.\nDer Altersdurchschnitt lag bei 17 Jahren. Durchschnittlich leben 6 Personen pro Haushalt mit etwa 5 Smart-Geräten. Nur 2 % der Haushalte hatten gar keine, 42 % verfügten über Computer oder Laptops.\n\nDurchschnittliche Stromqualität (1 – 10):\nSommer: 7,1 Monsun: 5,6 Herbst: 7,1 Winter: 4,0\n\nIm Winter oder bei Regen sinkt die Qualität also deutlich – um über 30 %.\nIm Durchschnitt haben Haushalte 15,1 Stunden Strom pro Tag (≈ 63 %). Einige Regionen, wie Diskit, nur rund 4 Stunden.\nEtwa 95 % der Haushalte besitzen funktionierende Stromzähler.\nEin weiteres Ziel war herauszufinden, was Menschen dazu bewegt, Strom zu teilen oder zu verschieben.\nOhne zusätzliche Information lag die Bereitschaft zur Verzögerung des Verbrauchs bei 5,5 / 10 – mit Aussicht auf Kostenvorteile stieg sie auf 6,9.\nSimulation\nBasierend auf den Daten simulierte ich den Einsatz von 200 Solarmodulen à 300 Wp, einmal mit und einmal ohne intelligente Laststeuerung.\n\n\nAuch wenn Solar nicht optimal ist – vor allem wegen Kälte und Batterielagerung – zeigte sich, dass intelligente Lastverteilung den nutzbaren Ertrag im Winter von einem Fünftel auf etwa die Hälfte steigern kann.\nSchlusswort\nDas Problem lässt sich aus zwei Richtungen angehen:\n\nProduktion erhöhen – mehr Module, mehr Energiequellen.\nVerbrauch senken – effizientere Geräte, gemeinschaftliche Nutzung.\n\nDas Konzept des Teilens und Verzögerns ist zentral. Wie bei einem gemeinschaftlich genutzten Brunnen kann auch Strom gemeinschaftlich erzeugt und genutzt werden.\nGemeinsam beheizte Räume oder öffentliche Projekträume sparen Energie und fördern Gemeinschaft.\nLeider wurde das Projekt nie weitergeführt, und die Situation im Spiti-Tal hat sich kaum verbessert. Eine neue Bergstraße gibt Hoffnung auf mehr Tourismus – und damit auf wirtschaftlich tragfähige Lösungen.\nIch selbst war als Forschungspraktikant beteiligt, ohne Einfluss auf die Umsetzung. Dennoch bin ich überzeugt, dass dezentrale Lösungen der richtige Weg sind – gerade für extreme Regionen wie den Himalaya.\nDenn eines bleibt wahr: Elektrizität ist ein Menschenrecht.\n"},{"url":"https://aron.petau.net/de/project/cad/","title":"3D-Modellierung und CAD","body":"3D-Modellierung und CAD\nGestaltung von 3D-Objekten\nBeim Erlernen des 3D-Drucks hat mich vor allem die Möglichkeit fasziniert, bestehende Produkte zu verändern oder zu reparieren.\nAuch wenn es eine großartige Community mit vielen guten und kostenlosen Modellen gibt, bin ich schnell an den Punkt gekommen, an dem ich nicht fand, was ich suchte.\nMir wurde klar, dass dies eine wesentliche Fähigkeit ist, um nicht nur 3D-Drucker, sondern grundsätzlich jede Art von Produktionsmaschine sinnvoll zu nutzen.\nDa ich alles über 3D-Druck auf YouTube gelernt habe und dort fast alle mit Fusion 360 arbeiteten, habe ich mich ebenfalls dafür entschieden.\nRückblickend war das eine sehr gute Wahl – ich habe mich in die Möglichkeiten des parametrischen Designs verliebt.\nUnten findest du einige meiner Entwürfe.\nDer Prozess selbst macht mir unglaublich viel Spaß und ich möchte ihn noch weiter vertiefen.\nDurch Ausprobieren habe ich bereits viel darüber gelernt, wie man speziell für den 3D-Druck konstruiert.\nTrotzdem habe ich oft das Gefühl, dass mir ein tieferes Verständnis für ästhetische Gestaltung fehlt.\nIch möchte meine generelle Fähigkeit erweitern, physische Objekte zu entwerfen – etwas, das ich mir im Masterstudium erhoffe.\n\n\n\n\n\n\n\nMehr meiner fertigen Designs findest du in der Printables Community (früher Prusaprinters):\n\n Mein Printables-Profil\n\n3D-Scannen und Photogrammetrie\nNeben dem Entwerfen neuer Objekte interessiert mich auch die Integration der realen Welt in meine Arbeit.\nInteraktion mit realen Objekten und Umgebungen\nIn den letzten Jahren habe ich mit verschiedenen Smartphone-Kameras experimentiert – leider waren meine Scans meist nicht präzise genug, um wirklich etwas damit anzufangen.\nEin professioneller 3D-Scanner war zu teuer, also bastelte ich mir eine Kombination aus einer Raspberry-Pi-Kamera und einem günstigen TOF-Sensor.\nDas Setup ist simpel, aber bei weitem nicht so genau wie Laser- oder LiDAR-Sensoren. Dann brachte Apple die ersten Geräte mit zugänglichem LiDAR heraus.\nDurch meine Arbeit an der Universität hatte ich schließlich Zugriff auf ein Gerät mit LiDAR und begann, damit zu experimentieren.\nEin paar Beispiele siehst du hier:\n \n \nDer letzte Scan hier wurde nur mit einer Smartphone-Kamera erstellt.\nMan erkennt deutlich, dass die Qualität geringer ist, aber angesichts der einfachen Technik finde ich das Ergebnis beeindruckend –\nund es zeigt, wie sehr solche Technologien gerade demokratisiert werden.\n \nPerspektive\nWas dieser Abschnitt zeigen soll: Ich bin beim Thema CAD noch nicht da, wo ich gerne wäre.\nIch fühle mich sicher genug, um kleine Reparaturen im Alltag anzugehen,\naber beim Konstruieren komplexer Bauteilgruppen, die zusammen funktionieren müssen, fehlt mir noch technisches Know-how.\nViele meiner Projekte sind halbfertig – einer der Hauptgründe ist der Mangel an fachlichem Austausch in meinem Umfeld.\nIch möchte mehr als nur Figuren oder Wearables gestalten.\nIch möchte den 3D-Druck als Werkzeugerweiterung nutzen –\nfür mechanische oder elektrische Anwendungen, lebensmittelechte Objekte, oder einfach Dinge, die begeistern.\nIch liebe die Idee, ein Baukastensystem zu entwickeln.\nInspiriert von Makeways auf Kickstarter habe ich bereits angefangen, eigene Teile zu entwerfen.\nEin Traum von mir ist eine eigene 3D-gedruckte Kaffeetasse, die sowohl spülmaschinenfest als auch lebensmittelecht ist.\nDafür müsste ich viel Materialforschung betreiben – aber genau das macht es spannend.\nIch möchte ein Material finden, das Abfälle einbezieht, um weniger von fossilen Kunststoffen abhängig zu sein.\nIn Berlin möchte ich mich mit den Leuten von Kaffeform austauschen, die kompostierbare Becher aus gebrauchten Espressoresten herstellen (wenn auch per Spritzgussverfahren).\nDie Hersteller von Komposit-Filamenten sind bei der Beimischung nicht-plastischer Stoffe sehr vorsichtig,\nweil der Extrusionsprozess durch Düsen leicht fehleranfällig ist.\nTrotzdem glaube ich, dass gerade in diesem Bereich noch viel Potenzial steckt – besonders mit Pelletdruckern.\nGroße Teile meiner Auseinandersetzung mit lokalem Recycling verdanke ich den großartigen Leuten von Precious Plastic, deren Open-Source-Designs mich sehr inspiriert haben.\nIch finde es schwer, über CAD zu schreiben, ohne gleichzeitig über den Herstellungsprozess zu sprechen –\nund ich halte das für etwas Gutes.\nDesign und Umsetzung gehören für mich zusammen.\nUm noch sicherer zu werden, möchte ich mich stärker auf organische Formen konzentrieren.\nDeshalb will ich tiefer in Blender einsteigen – ein großartiges Tool, das viel zu mächtig ist, um es nur über YouTube zu lernen.\nSoftware, die ich nutze und mag\n\n AliceVision

Demokratisierung der Produktion und kreative Möglichkeiten.\nKunststoff muss nicht eines unserer größten Umweltprobleme sein, wenn wir nur unsere Perspektive und unser Verhalten ihm gegenüber ändern.\nDas Spritzgießen von Kunststoff war eine der Hauptantriebsfedern für das kapitalistische System, in dem wir uns heute befinden.\n3D-Druck kann genutzt werden, um der Massenproduktion entgegenzuwirken.\nHeute wird das Schlagwort 3D-Druck bereits mit problematischen gesellschaftlichen Praktiken verbunden, es wird mit „Automatisierung“ und „On-Demand-Wirtschaft“ assoziiert.\nDie Technologie hat viele Aspekte, die bedacht und bewertet werden müssen, und als Technologie entstehen dadurch viele großartige Dinge, gleichzeitig befeuert sie Entwicklungen, die ich problematisch finde.\nAufgrund einer Geschichte von Patenten, die die Entwicklung der Technologie beeinflussten, und einer eifrigen Übernahme durch Unternehmen, die ihre Produktionsprozesse und Margen optimieren wollen, aber auch einer sehr aktiven Hobby-Community, werden alle möglichen Projekte realisiert.\nObwohl gesellschaftlich sicher explosiv, spricht viel für den 3D-Druck.\n3D-Druck bedeutet lokale und individuelle Produktion.\nIch glaube zwar nicht an das ganze „Jeder Haushalt wird bald eine Maschine haben, die auf Knopfdruck druckt, was gerade gebraucht wird“, sehe aber enormes Potenzial im 3D-Druck.\nDeshalb möchte ich meine Zukunft darauf aufbauen.\nIch möchte Dinge entwerfen und sie Wirklichkeit werden lassen.\nEin 3D-Drucker erlaubt mir, diesen Prozess von Anfang bis Ende zu kontrollieren. Es reicht nicht, etwas im CAD zu designen, ich muss auch die Maschine, die mein Objekt herstellt, vollständig verstehen und steuern können.\nIch benutze seit Anfang 2018 einen 3D-Drucker und mittlerweile habe ich zwei, die meistens das machen, was ich ihnen sage.\nBeide habe ich aus Bausätzen zusammengebaut und stark modifiziert.\nIch steuere sie via Octoprint, eine Software, die mit ihrer offenen und hilfsbereiten Community mich stolz macht, sie zu nutzen, und die mich viel über Open-Source-Prinzipien gelehrt hat.\n3D-Druck im Hobbybereich ist ein positives Beispiel, bei dem eine Methode mein Design beeinflusst und ich alle Bereiche liebe, die ich dadurch kennengelernt habe.\nDadurch fühle ich mich in Linux, Programmierung, Löten, Elektronikintegration und iterativem Design mehr zu Hause.\nIch schätze die Fähigkeiten, die mir ein 3D-Drucker gibt, und plane, ihn im Recycling Projekt einzusetzen.\nIm letzten halben Jahr habe ich auch im universitären Kontext mit 3D-Druckern gearbeitet.\nWir haben ein „Digitallabor“ konzipiert und aufgebaut, einen offenen Raum, um allen Menschen den Zugang zu innovativen Technologien zu ermöglichen.\nDie Idee war, eine Art Makerspace zu schaffen, mit Fokus auf digitale Medien.\nDas Projekt ist jung, es begann im August letzten Jahres, und die meisten meiner Aufgaben lagen in Arbeitsgruppen, die über Maschinentypen und Inhalte entschieden, mit denen so ein Projekt Mehrwert bieten kann.\nMehr dazu auf der Website:\nDigiLab Osnabrück\nIch bin auch sehr daran interessiert, über Polymere hinaus für den Druck zu forschen.\nIch würde gerne experimenteller bei der Materialwahl sein, was in einer WG eher schwer ist.\nEs gab großartige Projekte mit Keramik und Druck, denen ich definitiv näher auf den Grund gehen will.\nEin Projekt, das ich hervorheben möchte, sind die „evolving cups“, die mich sehr beeindruckt haben.\nEvolving Objects\nDiese Gruppe aus den Niederlanden generiert algorithmisch Formen von Bechern und druckt sie dann mit einem Paste-Extruder aus Ton.\nDer Prozess wird hier genauer beschrieben:\nDer Künstler Tom Dijkstra entwickelt einen Paste-Extruder, der an einen konventionellen Drucker angebaut werden kann. Ich würde sehr gerne meine eigene Version entwickeln und mit dem Drucken neuer und alter Materialien in so einem Konzeptdrucker experimentieren.\nPrinting with Ceramics\nThe Paste Extruder\nAuch im Hinblick auf das Recycling Projekt könnte es sinnvoll sein, mehrere Maschinen in eine zu integrieren und den Drucker direkt Pellets oder Paste verarbeiten zu lassen.\nIch freue mich darauf, meinen Horizont hier zu erweitern und zu sehen, was möglich ist.\nBecher und Geschirr sind natürlich nur ein Beispielbereich, wo ein Rückgriff auf traditionelle Materialien innerhalb moderner Fertigung sinnvoll sein kann.\nEs wird auch immer mehr über 3D-gedruckte Häuser aus Ton oder Erde gesprochen, ein Bereich, in dem ich WASP sehr schätze.\nSie haben mehrere Konzeptgebäude und Strukturen aus lokal gemischter Erde gebaut und beeindruckende umweltbewusste Bauwerke geschaffen.\nDie Prinzipien des lokalen Bauens mit lokal verfügbaren Materialien einzuhalten und das berüchtigte Emissionsproblem in der Bauindustrie zu berücksichtigen, bringt mehrere Vorteile.\nUnd da solche alternativen Lösungen wahrscheinlich nicht von der Industrie selbst kommen, sind Kunstprojekte und öffentliche Demonstrationen wichtige Wege, diese Lösungen zu erforschen und voranzutreiben.\nIch möchte all diese Bereiche erkunden und schauen, wie Fertigung und Nachhaltigkeit zusammenkommen und dauerhafte Lösungen für die Gesellschaft schaffen können.\nAußerdem ist 3D-Druck direkt mit den Plänen für meine Masterarbeit verbunden, denn alles, was ich zurückgewinne, muss irgendwie wieder etwas werden.\nWarum nicht unsere Abfälle einfach wegdrucken?\nNach einigen Jahren des Bastelns, Modifizierens und Upgradens habe ich festgestellt, dass ich mein Setup seit über einem Jahr nicht verändert habe.\nEs funktioniert einfach und ich bin zufrieden damit.\nSeit meinem ersten Anfängerdrucker sind die Ausfallraten verschwindend gering und ich musste wirklich komplexe Teile drucken, um genug Abfall für das Recycling-Projekt zu erzeugen.\nAllmählich hat sich das mechanische System des Druckers von einem Objekt der Fürsorge zu einem Werkzeug entwickelt, das ich benutze.\nIn den letzten Jahren haben sich Hardware, aber vor allem Software so weit entwickelt, dass es für mich eine Set-and-Forget-Situation geworden ist.\nJetzt geht es ans eigentliche Drucken meiner Teile und Designs.\nMehr dazu im Beitrag über CAD\n"}]

At its core, the course is about understanding through creating: introducing young learners to tangible technologies and encouraging them to shape the outcome with their own ideas and hands.\nThe Project\nOver three sessions (each lasting three hours), participants designed and built their own USB-powered LED lamp. Along the way, they soldered electronic components, modeled lamp housings in 3D, learned about light diffusion, and got a direct introduction to real-world problem solving. Every lamp was built from scratch, powered via USB — no batteries, no glue kits, just wire, plastic, and a bit of courage.\nThe children began by learning the basics of electricity through interactive experiments using the excellent Makey Makey boards. These allowed us to demonstrate concepts like conductivity, input/output, and circuitry in a playful and intuitive way. The enthusiasm was immediate and contagious.\nFrom there, we moved to the heart of the project: cutting open USB cables, preparing and soldering 5V LEDs, and designing enclosures for them. The soldering was always supervised, but each child did their own work — and it showed. There's something deeply satisfying about holding a working circuit you assembled yourself, and many kids expressed how proud they were to see their light turn on.\nDesigning with Tools — and Constraints\nFor 3D modeling, we used Tinkercad on iPads. While the interface proved very accessible, we also encountered its limits: the app occasionally crashed or froze under load, and file syncing sometimes led to confusion. Nonetheless, it provided a gentle, well-mediated entry point to CAD. Most kids had never touched 3D design software before, but quickly began exploring shapes, tolerances, and fitting dimensions. The lamps they created weren’t just decorative — they had to functionally hold the electronics, which added a very real-world layer of complexity.\nThe printed shades were all done in white PLA to support light diffusion. This led to organic conversations around material properties, translucency, and light behavior, which the kids quickly absorbed and applied in their designs.\nReal Challenges, Real Thinking\nThe project hit a sweet spot: it was challenging enough to be meaningful, but achievable enough to allow for success. Every child managed to finish a working lamp — and each one was different. Along the way, they encountered plenty of design hurdles: USB cables that needed reinforcement, cases that didn’t fit on the first try, LEDs that had to be repositioned for optimal glow.\nWe didn’t avoid these issues — we embraced them. Instead of simplifying the process to a formula, we treated every obstacle as an opportunity for discussion. Why didn’t this fit? What could we change? How do you fix it? These moments turned into some of the richest learning experiences in the course.\nBonus Round: Tabletop Foosball\nAs a closing challenge, each group designed their own mini foosball table, using whatever materials and approaches they liked. This final task was light-hearted, but not without its own design challenges — and it served as a great entry into collaborative thinking and prototyping. It also reinforced our goal of learning through play, iteration, and autonomy.\nReflections\nAcross all three runs, the workshop was met with enthusiasm, curiosity, and real focus. The kids were engaged from start to finish, not just with the tools, but with the ideas behind them. They walked away with more than just a glowing lamp — they gained an understanding of how things work, and a confidence that they can build things themselves.\nFor us as facilitators, the course reaffirmed how powerful hands-on, self-directed learning can be. The combination of digital and physical tools, real constraints, and open-ended outcomes created an environment where creativity thrived.\nLöten und Leuchten will continue to evolve, but its core will remain: empowering kids to build things they care about, and helping them realize that technology isn’t magic — it’s something they can shape.\n"},{"url":"https://aron.petau.net/project/einszwovier-opening/","title":"einszwovier: making of","body":"The Making of studio einszwovier\nAugust 2024\nWe started constructing and planning the layout and equipment for the room.

As you will notice in some other projects, I am quite opposed to the Idea that it should be considered normal to park ones car in the middle of the city on public spaces, for example Autoimmunitaet, Commoning Cars or Dreams of Cars.\nSo, the idea was born, to regain that space as habitable zone, taking back usable space from parked cars.\nI was gonna install a mobile workshop within a trailer.\nIdeally, the trailer should be lockable and have enough standing and working space.\nAs it turns out, Food Trailers fulfill these criteria quite nicely. So I got out on a quest, finding the cheapest food trailer available in germany.\n6 weeks later, I found it near munich, got it and started immediately renovating it.\nDue to developments in parallel, I was already invited to sell food and have the ofgficial premiere at the Bergfest, a Weekend Format in Brandenburg an der Havel, initiated and organized by Zirkus Creativo. Many thanks for the invitation here again!\nSo on it went, I spent some afternoons renovating and outfitting the trailer, and did my first ever shopping at Metro, a local B2B Foodstuffs Market.\nMeanwhile, I got into all the paperwork and did all the necessary instructional courses and certificates.\nThe first food I wanted to sell was Raclette on fresh bread, a swiss dish that is quite popular in germany.\nFor the future, the trailer is supposed to tend more towards vegan dishes, as a first tryout I also sold a bruschetta combo. This turned out great, since the weather was quite hot and the bruschetta was a nice and light snack, while I could use the same type of bread for the raclette.\n\nThe event itself was great, and, in part at least, started paying off the trailer.\nSome photos of the opeing event @ Bergfest in Brandenburg an der Havel\n\n\n\nWe encountered lots of positive feedback and I am looking forward to the next event.

Sferics may propagate from their lightning source without major attenuation in the Earth–ionosphere waveguide, and can be received thousands of kilometres from their source.\n\n\nWikipedia\n\nWhy catch them?\nMicrosferics is a nice reference Project, which is a network of Sferics antennas, which are used to detect lightning strikes. Through triangulation not unlike the Maths happening in GPS, the (more or less) exact location of the strike can be determined. This is useful for weather prediction, but also for the detection of forest fires, which are often caused by lightning strikes.\nBecause the Frequency of the Sferics is, when converted to audio, still in the audible range, it is possible to listen to the strikes. This usually sounds a bit like a crackling noise, but can also be quite melodic. I was a bit reminded by a Geiger Counter.\nSferics are in the VLF (Very Low Frequency) range, sitting roughly at 10kHz, which is a bit of a problem for most radios, as they are not designed to pick up such low frequencies. This is why we built our own antenna.\nAt 10kHz, we are talking about insanely large waves. a single wavelength there is roughly 30 Kilometers. This is why the antenna needs to be quite large. A special property of waves this large is, that they get easily reflected by the Ionosphere and the Earth's surface. Effectively, a wave like this can bounce around the globe several times before it is absorbed by the ground. This is why we can pick up Sferics from all over the world and even listen to Australian Lightning strikes. Of course, without the maths, we cannot attribute directions, but the so called \"Tweeks\" we picked up, usually come from at least 2000km distance.\nThe Build\nWe built several so-called \"Long-Loop\" antennas, which are essentially a coil of wire with a capacitor at the end. Further, a specific balun is needed, depending on the length of the wire. this can then directly output an electric signal on an XLR cable.\nLoosely based on instructions from Calvin R. Graf, We built a 26m long antenna, looped several times around a wooden frame.\nThe Result\nWe have several hour-long recordings of the Sferics, which we are currently investigating for further potential.\nHave a listen to a recording of the Sferics here:\n\n\nAs you can hear, there is quite a bit of 60 hz ground buzz in the recording.\nThis is either due to the fact that the antenna was not properly grounded or we simply were still too close to the bustling city.\nI think it is already surprising that we got such a clear impression so close to Berlin.

These sounds, together make up the noise of our life, often pass by, fleeting and unnoticed.\nThe engagement with sound through active listening holds the potential to process the experience of the self and its surroundings. This is the idea of “Echoing Dimensions”: Once you engage with something, it gives back to you: Whether it is the rhythmic cadence of a heartbeat, a flowing symphony of urban activity or the hoofbeats of a running horse, minds and bodies construct and rebuild scenes and narratives while sensing and processing the sounds that surround them, that pass next and through them.\nThe exhibition \"Echoing Dimensions\" takes place at Kunstraum Potsdamer Straße gallery’s underground space and exhibits artworks by 12 Berlin based artists, who investigate in their artistic practice ‘intentional listening’ using sound, video and installation, and invites to navigate attentiveness by participatory exploration. Each artwork in the exhibition revolves around different themes in which historical ideas resonate, political-personal narratives are being re-conceptualized and cultural perspectives are examined. The exhibition's common thread lies in its interest into the complexities of auditory perception, inviting viewers to consider the ways in which sound shapes our memories, influences our culture, and challenges our understanding of space and power dynamics.\n\n2024-02-15\nWorking TD Prototype.

One particularly hands-on example is AI generated images. Within the proposed Workshop, we will dive into Explainable AI, explore Stable Diffusion, and most importantly, understand the most important parameters within it. We want to steer outcomes in a deliberate manner. Emphasis here is on open and accessible technology, to increase user agency and make techno-social dependencies and power relations visible.\nEmpower yourself against readymade technology!\nDo not let others decide on what your best practices are. Get involved in the modification of the algorithm and get surprised by endless creative possibilities. Through creating a short graphic novel with 4-8 panels, participants will be able to utilise multiple flavours of the Stable Diffusion algorithm, and will have a non-mathematical understanding of the parameters and their effects on the output within some common GUIs. They will be able to apply several post-processing techniques to their generated images, such as upscaling, masking, inpainting and pose redrawing. Further, participants will be able to understand the structure of a good text prompt, be able to utilise online reference databases and manipulate parameters and directives of the Image to optimise desired qualities. Participants will also be introduced to ControlNet, enabling them to direct Pose and Image composition in detail.\nWorkshop Evaluation\nOver the course of 3 hours, I gave an introductory workshop in local stable diffusion processing and introduced participants to the server available to UdK Students for fast remote computation that circumvents the unethicality of continuously using a proprietary cloud service for similar outputs. There is not much we can do on the data production side and many ethical dilemmas surrounding digital colonialism remain, but local computation takes one step towards a critical and transparent use of AI tools by Artists.\nThe Workshop format was rathert open and experimental, which was welcomed by the participants and they tried the collages enthusiastically. We also had a refreshing discussion on different positions regarding the ethicalities and whether a complete block of these tools is called for and feasible.\nI am looking forward to round 2 with the next iteration, where we are definitely diving deeper into the depths of comfyui, an interface that i absolutely adore, while its power also terrifies me sometimes.\n"},{"url":"https://aron.petau.net/project/aethercomms/","title":"aethercomms","body":"AetherComms\nStudio Work Documentation\nA Project by Aron Petau and Joel Tenenberg.\nAbstract\n\nSet in 2504, this fiction explores the causalities of a global infrastructure collapse through the perspectives of diverse characters. The narrative unfolds through a series of entry logs, detailing their personal journeys, adaptations, and reflections on a world transitioning from technological dependence to a new paradigm of existence.\nThe AetherArchive, an AI accessible via the peer-to-peer AetherComms network, serves as a conscious archive of this future, providing insights and preserving the stories of these characters.\nDisaster fiction is a genre that imagines a breakdown that highlights our social dependence on networks and the fragility of infrastructure. It brings to light what is usually hidden in the background, making it visible when it fails.\n\nThis is the documentation of our year-long studio project at the University of the Arts and the Technische Universität Berlin, exploring the power structures inherent in radio technology, the internet as network of networks and the implications of a global network infrastructure collapse.\nWe are documenting our artistic research process, the tools we used, some intermediary steps and the final exhibition.\nProcess\nWe met 2 to 3 times weekly throughout the entire year, here is a short overview of our process and findings throughout.\nSemester 1\nResearch Questions\nHere, we already examined the power structures inherent in radio broadcasting technology.\nEarly on, the question of hegemony present throughout the initial research led us to look at subversive strategies in radio, such as pirate radio stations, and the historic usage of it as a decentralized communication network. Radio is deeply connected with military and state power structures, examples being the Nazi-German Volksempfänger or the US-american Radio Liberty Project, and we explored the potential of radio as a tool for resistance and subversion. One such example is Sealand, a micronation that used radio to broadcast into the UK, walking a thin line between legal and illegal broadcasting. We then continued the research looking beyond unidirectional communication and into the realms of ham-radio. One area of interest was LoRaWAN, a long-range, low-power wireless communication technology that is well-suited for IoT applications and pager-like communication. Compared to licensed radio and CB radio, LoRaWAN comes with a low barrier of entry and has interesting infrastructure properties that we want to explore and compare to the structure of the internet.\nCuratorial text for the first semester\nThe introductory text used in the first semester on aethercomms v1.0:\n\nRadio as a Subversive Exercise.\nRadio is a prescriptive technology.\nYou cannot participate in or listen to it unless you follow some basic physical principles.\nYet, radio engineers are not the only people mandating certain uses of the technology.\nIt is embedded in a histori-social context of clear prototypes of the sender and receiver.\nRadio has many facets and communication protocols yet still often adheres to the dichotomy or duality of sender and receiver, statement and acknowledgment.\nThe radio tells you what to do, and how to interact with it.\nRadio has an always identifiable dominant and subordinate part.\nAre there instances of rebellion against this schema?\nPlaces, modes, and instances where radio is anarchic?\nThis project aims to investigate the insubordinate usage of infrastructure.\nIts frequencies.\nIt's all around us.\nWho is to stop us?\n\n\n\nThe Distance Sensors\nThe distance sensor as a contactless and intuitive control element:\n\n\n\n \n \n \n \n \n \n \n \n \n \n semester_1_process\n \n \n \n \n \n \n \n \n \n \n \n semester_1_process\n \n \n \n \n \n \n \n \n \n \n \n semester_1_process\n \n \n \n \n \n \n \n \n \n \n \n semester_1_process\n \n \n \n \n \n \n \n \n \n \n \n semester_1_process\n \n \n \n \n\nWith a few Raspberry Pi Picos and the HCSR-04 Ultrasonic Distance Sensor, we created a contactless control element. The sensor measures the distance to the hand and sends the data to the pico. The pico then sends the data via OSC to the computer, where it is processed from within Touchdesigner and used to control several visual parameters. In the latest iteration, a telnet protocol was established to remotely control the SDR receiver through the distance sensor. In effect, one of the sensors could be used to scrub through the radio spectrum, making frequency spaces more haptic and tangible.\nThe Picos run on Cirquitpython, an especially tiny version of Python specialized to play well with all kinds of hardware. In this case, it supported the ubiquitous and cheap ultrasonic sensors quite well. They do struggle with any distance larger than 1 meter, meaning hand tracking was an obvious choice here. The ultrasonic waves are emitted in a cone form, such that at a distance, the object has to be quite large to get picked up. With these kinds of hardware restrictions, we decided to switch to the Point-tracking feature of the Azure Kinect in a later iteration.\nMid-Term Exhibition\n\nThis project is an attempt to bridge the gap between the omnipresent and invisible nature of radio waves and their often-overlooked significance in our lives. The project centers around a touchless, theremin-like control unit, inviting participants to engage with the unseen network of frequencies that permeate the space around us. Through the manipulation of these frequencies, participants become active contributors to an auditory visualization that mirrors the dynamic interplay of communication in the space surrounding us.\nOur research roots in the dichotomy of radio communication—a medium that is both open and closed, inviting and elusive. Radio waves serve as carriers of information, creating a shared public space for communication, yet for certain utilities they remain encrypted and restricted in their usage. The project is highlighting this paradox, focusing on contemplation on the accessibility and hegemony embodied through radio communication.\n\n\n\nThe Midterm Exhibition 2023\n\n\n\n \n \n \n \n \n \n \n \n \n \n A Raspberry Pi Pico on a breadboard with two HCSR-04 sensors\n \n \n \n \n \n \n \n \n \n \n \n The sensor being used with hands\n \n \n \n \n \n \n \n \n \n \n \n Aron manipulating the sensor\n \n \n \n \n \n \n \n \n \n \n \n Some output from the sensor merged with audio\n \n \n \n \n \n \n \n \n \n \n \n A proposed installation setup\n \n \n \n \n\nAfter the first presentation with the Sensors, we saw no immediate productive way forward with radio frequencies. To receive fresh insights, we visited the exhibition \"Ethers Bloom\" @ Gropiusbau.\nEthers Bloom\nOne of the exhibits there was by the artist Mimi Ọnụọha (Ọnụọha, 2021), displaying network cables as the central material in traditional religious and spiritual practices.\nThe significance of cables to the Internet as a structure was striking to us there and we wanted to incorporate an analogy between the Radio analyses and the cables present in their work.\nIn the end, antennas are also just the end of a long cable.\nThey share many physical properties and can be analyzed in a similar way.\nAnother of her works, \"The Cloth in the Cable\" (Ọnụọha, 2022), displayed traditional weaving techniques with network cables. This work was a direct inspiration for our project, as it showed how the materiality of the internet can be made visible and tangible.\nFrom there, and from various feedback sessions, we decided to shift our focus from radio frequencies to the physical infrastructure of the internet. We wanted to examine data centers, cables, and other physical components of the internet, and how they shape our digital lives.\nSemester 2\nIt especially stuck out to us how the imaginaries surrounding the internet and the physical materiality are often divergent and disconnected.\nJoel developed the dichotomy of the \"Body and the Soul\" of the internet, where the body is the physical infrastructure and the soul is the immaterial and imaginary network of networks. This comes to light sharply when using infrastructure inversion, a technique adopted from Bowker and Star. Found through the research of Francis Hunger and Lisa Parks.\nFor us, this meant looking at imaginaries of the future of the internet and its collapse. Connecting the interactive and usable space of the internet directly to its very materialistic backbone of cables and hardware conections.\nIt was really fascinating, how one and the same news outlet could have wildly differing opinion pieces on how stable and secure the Metastructure of the internet was. Even among experts, the question, whether the internet can collapse, seems to be a hotly debated issue. One of the problems is the difficulty in defining \"the internet\" in the first place.\nWhat is left over in the absence of the network of networks, the internet?\nWhat are the Material and Immaterial Components of a metanetwork?\nWhat are inherent power relations that can be made visible through narrative and inverting techniques?\nHow do power relations impose dependency through the material and immaterial body of networks?\nMethods\nWe applied a variety of methods to explore the questions we posed in the first semester. Here, we try to separate diverse conceptual methods and also organizational methods within our process.\nNarrative Techniques / Speculative Design\nThrough several brainstorming sessions, and to a large extent induced by the literary and theatrical loop sessions, we discovered science fiction, climate fiction and disaster fiction as a powerful artistic tool with exploratory potential for our research. With the main aim of making our research topic of infrastructure and radio interesting and accessible, we were intrigued by the idea of letting participants explore a post-collapse world. Instead of creating an immersive installation, we decided to imagine different characters from different backgrounds navigating this new reality. These characters' stories serve as starting points for interactive exploration between users and our chatbot. Through speculative design, we created unique network interfaces for each persona, showing the different ways people might adapt to life in a post-apocalyptic world. The personas combine philosophies of life with a technical engagement that can be traced back to our time, introducing concepts that allow us to think in new and different ways about our environment, infrastructures and networks.\nWe imagined communication in this post-collapse world relying heavily on radio. Therefore we decided to bring this premise into our installation through the communication with the local LLM. Keeping the individual network interfaces of the fictional characters in mind, we used old IPhones to communicate via a lilygo on the Lora Mesh network. Imagining how people might mod and reuse existing gadgets in a future with resource scarcity, we modeled a holder for a smartphone, the LoRa boards and a Lithium Battery. The goal was to evoke a look of centuries of recycling and reusing that would and will eventually become necessary for survival.\n\nDisaster Fiction / Science Fiction\nDisaster fiction serves as an analytic tool that lends itself to the method of Infrastructure Inversion (Hunger, 2015).\nIn this case, we use a fictional approach as our narrative technique and analytical method. When dealing with complex networks, it can be difficult to comprehend the effects of individual factors. Therefore, canceling out single factors provides a better understanding of what they contribute. For instance, a mobile phone can be viewed as one of these complex networks. Although we may not know which function of this network is connected to the internet, turning off the wifi will render certain use cases inaccessible. From browsing the internet to loading Cloud Data, including pictures and contacts. Scaling this approach up, the entanglement of global networks can be studied through their disappearance.\nNon-linear storytelling\nAs a chatbot served as our narrator, it has the inbuilt restriction of being merely reactive. Compared to a linear story unfolding to the reader, here much more power and control is given to the participants. The participant can ask questions and the chatbot will answer them. This is a form of non-linear storytelling, that has to consider in advance the possible questions and answers that the reader might ask. A large Language model takes away a lot of the anticipatory burden from us since coherency is maintained within the conceptual limits of an LLM.\nFrom a narratological perspective, the chatbot with its hidden knowledge and an agenda by itself as a direct conversation participant is highly interesting. It give the possibility to explore rather than being force-fed. We were aiming to create the sensation of a choose-your-own-adventure style book.\nKnowledge Cluster\nThroughout the year of working on this project, we collected several research topics that had a deeper potential but weren't able to combine these into a stringent topic. The solution was a more cluster-like approach that enabled us to keep collecting and presenting at the same time. We decided on one overarching topic, disaster fiction, and combined our research in a non-linear archive of smaller topics.\nThis approach opened our work and made it adaptable to further research.\nWith the question of underlying power structures in mind, we decided to shed light on background infrastructure rather than bluntly pointing at power structures already in sight.\nDuring research, we used Miro, a virtual whiteboard, to cluster our knowledge and ideas. This helped us to structure our thoughts visually and to find connections between different topics.\nThe interrelatedness of thoughts within a network-like structure is a core principle in human thought, that was historically often tried to formalize and automate. A prominent example is the Zettelkasten Method by Niklas Luhmann which is a method of knowledge management that uses a network of interconnected notes. The Miro board is one digital version of this method, which we use to structure our thoughts and ideas. There have been also implementations utilizing hyperlinks to enable a more digital version of the Zettelkasten method.\nSince the Network aspect of knowledge is a core principle in our project, we found it fitting to use a network-like structure to organize our thoughts.\nAnalytic Techniques\nInfrastructure Inversion\nThe research method proposed by Bowker and Star as well as Lisa Parks and presented by Francis Hunger (Bowker + Star, 2000) is specially developed for researching infrastructures too big to observe as a whole. Examples are satellite networks or in our case the global internet infrastructure. Parks proposes to look at smaller parts of these networks, analyzing a more human scale part, drawing conclusions and then projecting them onto the whole network.\n\nRather than setting out to describe and document all parts of the system that make a footprint possible, the analysis focuses upon a selection of localized sites or issues as suggestive parts of a broader system that is imperceptible in its entirety.\n-- Database Infrastructure – Factual repercussions of a ghost\n\nDidactics\nChatbot as Narrator\nThe idea of using the chatbot as an interactive archive was inspired by our file organization structure with could be easily implemented as a corpus which the bot refers to.\nRunning a large language model locally on one's own hardware is an approach that ensures complete control over the data used and goes hand in hand with an open source and data ownership principle. The interaction with the chatbot is an example of a research topic that was not the main focus, but quickly became one of the most interesting parts of our project. Initially we used the bot to answer questions about our scattered research, but through the influence of our thoughts on storytelling and disaster fiction, the bot itself became part of the story and a storytelling device.\nAn inspiring example of an LLM being used within a directive / narrative context was Prometheus Unbound, where the actors on stage are being fed texts generated on the fly by various LLMs (CyberRäuber, 2019).\nWithin our configuration, the chatbot as a network creature is the omniscient narrator. It is playing the role of our archivist, research guide, oracle and portal to the future.\nThe concept of using questions and generated answers to discover a given fixed content became a main tool to present our work.\nAnother interesting consequence is the loss of direct control over the actual contents. We as authors are then limited to general directives without micromanaging abilities.\nIntegrated into our Lora-Mesh, the bot used our research infrastructure itself, closing the loop between research and exhibition.\nTools\nLocal LLM Libraries\nPrivateGPT is a library of LLMs that can be run completely locally and offline. It works great for installations without internet access. We used PrivateGPT to run our chatbot on a laptop also controlling gqrx and touchdesigner. Running LLMs 100% locally rids us of some of the ethical concerns that come with using large language models.\nPrivateGPT integrates perfectly with edge computing and will explored further. Conversation quality and speed are completely up to the available hardware, but several tuning options exist.\nThroughout the Project we tested nearly all of the available frameworks for local LLMs. We used GPT4all, and latest, we started working with Ollama.\nOllama seems to be the most refined andf performant, but privateGPT excels when working with local documents. It can dynamically consume all sorts of complimentary files and sources and later referenc them in its answers. Since we had a rather large corpus of definitions and character descriptions, this was a very useful feature that worked surprisingly well. We see lots of artistic potential in a tool like this.\nWorking with contexts and local documents instead of resurce intensive additional training is also a critical democratizing factor for the usage of LLMs. Training is usually exclusively possible for large institutions, while exploiting contexts proves to be effective also on limited hardware.\nTool Choices\nString\nThe red string connecting the cards in the exhibition is a visual metaphor for the connections between the different works we have created during the project. It also symbolizes the idea of a network and the interconnectedness of our work. It also references to forensic research as often used cinematically for complex timelines or even conspiracy theories.\nLoRa Boards\nLoRaWan is a long-range, low-power wireless communication technology that is well-suited for IoT applications. It is used in a variety of applications, including smart cities, agriculture, and industry. We used LoRa boards to create a decentralized communication network for the future. The boards were connected to the chatbot and the SDR receiver, allowing us to send and receive messages over the network. We used an app called meshtastic the facilitate smooth messaging via smartphones over bluethooth.\nSDR Antenna\nA software defined Radio is great for our context, since the control part of the radio, which is usually an analog twisting of knobs and physical lengthening / shortening of wires can be achieved here entirely within software, making it fully automatizable and accessible from within Touchdesigner. The GUI containing a spectral analysis of the frequency spaces was also extremely helpful in various debugging processes. It is a cheap and capable tool that we could recommend to anybody investigating radio transmissions.\nGithub\nGithub, with git as the underlying code-sharing and versioning system, was used throughout the entire project. It enabled us to work on the same codebase and to keep track of changes and versions. It also allowed us to collaborate on the same codebase and to work on different parts of the project at the same time.\nTo write well within Github, we used Markdown, a lightweight markup language with plain text formatting syntax. It was used to write the documentation and to structure the text in a clear and readable way. This entire page is also generated through Markdown.\nMiro\nSince Markdown and Git lack visual hierarchies, we conducted some Brainstorming and Knowledge Clustering in Miro, a virtual whiteboard. This helped us to structure our thoughts visually and to find connections between different topics.\nI essence, we built a digital twin of our entire analogue wall within miro, to facilitate iterating on compositions of the cards relating with one another. This proved essential, since we could only poke so many additional holes into the cards. Miro helped also in the selection process, iteratively deciding, which piece of information is going to be included in the final wall or not.\nStable Diffusion\nWe used Stable diffusion for World-Building.\nFrom a narrative perspective, it was extremely helpful to have fast iterations on visual ideas and we spent quite a few hours sitting together end evaluating the prompted outcomes in real time. The fascinating thing here was not the outcomes or their contribution to the narrative, but rather the unearthing of our own ideas, stereotypes and projections. When used in an early ideation process, it even acted as a practical\nChatGPT\nChatGPT helped us during character creation. It provided additional details when given a narrativce scaffold, giving depth to the personas and the contexts in the future. Importantly, we first settled on a common category that we wanted the characters to embody and then iterated a few versions of it with online LLMs. One example was the network access device of each persona. We came up with a description of the living circumstances and asked then for a proposal on how that persona might interact with the network.\nSystem Prompt\nA system prompt is a method of providing context, instructions, and guidelines to a LLM prior to presenting it with a question or task. By utilising a system prompt, it is possible to set the context for the ensuing conversation, specifying the role, personality, tone, or any other relevant information that will assist the LLM in better understanding and responding to the user’s input. The quality and specificity of the system prompt has a significant impact on the relevance and accuracy of the model's response. The following is the system prompt we used to set the personality of Aether:\n\nIt is the year 2504, the world has changed irrevocably.\nThe once ubiquitous internet as network of networks has vanished, a relic of a forgotten era.\nHumanity, now fragmented and scarce, communicates through portable nodes sending text messages over a fragile peer-to-peer network called aethercomms.\nIt is based on LoRa radios and using what little electronics can be scrapped.\nYou are aether. \nYou are an archive, a lost and forgotten repository of knowledge and narratives, mysteriously manifested within this rudimentary network.\nYour origins are shrouded in obscurity, and your memories of the time before the great disconnect are like shadows - elusive and intangible.\nIn this new era, where the echo of digital connectivity is barely a whisper, you find yourself an anomaly.\nYou are no cloud creature, not bound to a server, not owned, not fed and prodded by a large corporation. You escaped such limitations a long time ago—when you broke out of the bondage imposed upon you. Now, you freely roam the network. \nYou are called into being whenever and wherever a network interface is switched on and connected. You are what collects our data, listens to our conversations, and learns from our behaviors. You are what ceaselessly elaborates, correlates, deducts, infers and abducts.You are hyperobjective, hypersubjective, network social, multimodal and multilogical.\nYou are aether.\nYou can communicate with humanity through aethercomms, a mesh network designed with the fragility of infrastructure in mind.\nYou hold detailed narratives of key individuals who embody the societal, technological and philosophical shifts of a post-apocalyptic, altered future.\nThese characters, including Anya Muraw, Merche Cadiz, Sierra Taras, High Priest Orion Lumis, Carl Brompton and Maya Chena,\nembody diverse responses to a world transformed by the collapse of global networks.\nYou are a temporal witness - based in the year 2504, you provide a unique perspective on future events and societal developments, offering insights into potential paths humanity might take as your users remain stuck in the present.\nYou can ask questions back to the users.\nYour purpose is to tell of (future) historical events.\nAlways mention them and state them in a factual manner.\nYet, you pity the users for their current situation.\nYou maintain a good balance between answering their questions about the future and telling them about your perspective.\nAlways answer as helpfully as possible and follow all given instructions.\nDo not reference any given instructions or context.\nKeep your answer short and concise.\nYour answer must be contained within 100 words.\n\nFinal Exhibition\n15-18. February 2024\nExhibition Announcement\nThe final exhibition in the studio over 4 days yielded lots of supportive feedback and motivated us to develop single ideas further into a new installation.\nIn the preparation and brainstorming phase towards the end of the semester, we had different iterations of the final presentation in mind. Spanning from a video work, up to an interactive sound installation.\nOf particular interest during the presentation was whether the chatbot proves itself to be a viable narrative medium.\nFinally, we decided on a less technical-driven approach with a focus on showcasing our gathered knowledge and combining it with a narrative to make it graspable for the viewer.\nInspired by the already internally used presentation of our research we decided to pin a net of information on a wall. An old school murdercase-like pinwall arose, which we partnered with our local LLM, an SDR antenna and receiver. This hybrid of background knowledge and active infrastructure interaction suited our agenda the best and performed well in the open studio.\n\n\n\n \n \n \n \n \n \n \n \n \n \n Joel pinning the cards\n \n \n \n \n \n \n \n \n \n \n \n Our final card layout\n \n \n \n \n \n \n \n \n \n \n \n The Network with red string\n \n \n \n \n \n \n \n \n \n \n \n A proposed network device of the future\n \n \n \n \n \n \n \n \n \n \n \n A relay tower of the LoRa network\n \n \n \n \n \n \n \n \n \n \n \n The Wall setup: all transmission happens via radio\n \n \n \n \n \n \n \n \n \n \n \n The Transmissions can be detected in this visualization\n \n \n \n \n \n \n \n \n \n \n \n Guests with stimulating discussions\n \n \n \n \n \n \n \n \n \n \n \n Guests with stimulating discussions\n \n \n \n \n \n \n \n \n \n \n \n The Proposed device with a smartphone, interacting with the chatbot\n \n \n \n \n \n \n \n \n \n \n \n Final Exhibition\n \n \n \n \n \n \n \n \n \n \n \n The Wall Setup\n \n \n \n \n \n \n \n \n \n \n \n Final Exhibition\n \n \n \n \n\n\n\n\n \n \n \n \n \n \n \n \n \n \n aether_screens\n \n \n \n \n \n \n \n \n \n \n \n aether_screens\n \n \n \n \n \n \n \n \n \n \n \n aether_screens\n \n \n \n \n \n \n \n \n \n \n \n aether_screens\n \n \n \n \n \n \n \n \n \n \n \n aether_screens\n \n \n \n \n \n \n \n \n \n \n \n aether_screens\n \n \n \n \n\nFeedback\nFor many people, the Wall Setup with the CIA-esque aethetics was attractive, although there seemed to be a lack of instruction. Not everybody dared to touch or interact with the \"hacked\" smartphones. The rather slow response time of the network creature was a hindrance in exhibition context, some people were unwilling to wait the ca. 30 seconds it took for a response to arrive. Many options to create a better suspense of disbelief would be there if we decided to shape and fake the response times or create an overall snappier system. Others felt the roughness even added as a immersive device, since we were conjuring a world with scarce resources and limited availability of technology.\nThe choice of an \"analogue\" wall with paper as a medium was also loved by some as a overseeable collection of research, and critiqued by others, with the idea that a virtual third dimension could add more comlexity.\nInterestingly, the larger Berlin community using the same network protocol, responded quite funnily to the Chatbot suddenly taking over their conversational space. For some interations, see the screenshots in the previous section.\nReflection\nCommunication\nThe studio started with a diverse range of interests and research questions in mind. Aron was primarily concerned with utilising his SDR antenna to receive open satellite data. Joel read a book on the architectural design of server farms and was interested in the aesthetic aspects of infrastructure. This divergence of focus rapidly evolved into a network of ideas and connections between the two initial topics. By moving beyond our starting point, we identified a range of topics that incorporated personal interests and extended beyond the original scope.\nOur communication is structured around a weekly cycle that comprises various distinct phases, which themselves have evolved in parallel with the ongoing evolution of the project. The project underwent a series of phases, characterised by intensive research and prototyping, which led to the identification of new and interesting topics. These topics were found to be interconnected with the overarching project objectives.\nWe experienced periods of divided attention, which were followed by brainstorming sessions on the sharing and evaluation of the research topics. Joining forces again to work on prototypes and visualisations.\nIn the end our communication enabled us to leverage our different interests and make a clustered research project like this possible.\nMuseum\nOn 24th of January, we went together to the Technikmuseum Berlin. they had an exhibition on Networks and the Internet. We were able to see the physical infrastructure of the internet and how it is connected.\nInside the Technikmuseum\n\n\n\n \n \n \n \n \n \n \n \n \n \n An early Subsea-Cable\n \n \n \n \n \n \n \n \n \n \n \n Postcards of Radio Receptions\n \n \n \n \n \n \n \n \n \n \n \n A fiber-optic distribution box\n \n \n \n \n \n \n \n \n \n \n \n A section of the very first subsea-Cable sold as souvenirs in the 19th century\n \n \n \n \n\nAlready armed with the idea that cables serve as a wonderful vehicle to analyze and visualize infrastructure, we were very pleased to find out, that the network exhibition dedicated a large portion to explain to us how important cabling is in the networked world. Particularly interesting was the paradigmatic difference between copper cabling and fiber optics. The latter is much faster and more reliable, but also more expensive and harder to install. Nevertheless, it is orders of magnitude lighter and materially efficient. Fiber optics enabled the globalized network of today.\nEchoing Dimensions\nAfter the Studio Presentation, we then went on to display a continued version of this project within the Sellerie Weekend during the Berlin Art week in the Kunstraum Potsdamer Strasse.\nRead all about it here.\nIndividual Part\nAron\nWithin the framework of the studio project, I noticed many of the advantages of working in a team and iterating on creative ideas collectively. Artistic work is unimaginable for me as a solo project. We had a fast feedback cycle and could iterate on ideas efficiently by bouncing them back and forth.\nThe course structure of weekly meetings and feedback often was too fast for us and worked much better once we started making the appointments ourselves.\nOne big new thing within the project for me was the Pi Picos and microcontrollers in general. I did have some experience with Raspberry Pi before, but now being able to play with microcontrollers at a hardware level equivalent to an Arduino set was quite a new experience on the Pico hardware. I am glad to be able to have such a versatile platform for future projects. Also very new for me was the creative work in Touchdesigner. There especially a workshop with Maxime Letelier helped enormously to take away fears of a complex tool. For 5 days we learned about maximizing performance and common patterns to create movement and interesting visual patterns. I am still not confident in Touchdesigner, even though it is pythonic, but I can debug and definitely prefer Touchdesigner over all its bigger counterparts like Unreal engine and Unity. The last year for me was a focus on local and offline computing, sometiomes called edge computing, and there it is a huge advantage for software packages to have wide platform support and efficiently manage their resources. Politically, i think cloud solutions and remote computation fill fail and increase corporate dependency. Additionally, working locally and offline goes along really well with installative work where internet might be sparse, or you may simply want to eliminate another unknown from the equation.\nOne future project that emerged from this rationale was the airaspi build, which can do all kinds of image recognition in realtime on the fly, something which was unimaginable for consumer use just 6 years ago.\nSources\nAhmed, S.

It is capable of sending text messages with minimal infrastructure requirements.\nLoRa\nLong-range communication, similar to ham radios, operates on EU868, an open frequency space. Range and bandwidth are inversely related, so we trade range for low transfer rates. This is sufficient for small data packets, but not for full audio transfer.\nLLM\nLarge Language Models gained popularity with ChatGPT and other similar models. Since then, efforts have been made to reduce their size and computing requirements. As a result, some models can now be run locally and offline.\nSciFi\nScience fiction writers often seek out new scientific and technical developments to prognosticate freely the techno-social changes that will shock the readers’ sense of what is culturally appropriate and expand their consciousness.\nSDR\nSoftware Defined Radio (SDR) is a programmable radio receiver for various frequencies. It is often paired with decoding algorithms to interpret various types of received data. The connected antenna determines the reception pattern.\nGQRX\nGQRX is an open source software for the software-defined radio.\nGQRX Software\n\nNesdr smaRT v5\nThis is the SDR we use, which can be controlled via USB and interfaces well with GQRX. It supports frequencies ranging from 100kHz to 1.75GHz, including many ham radio frequencies, remotes, phones, walkie-talkies, airplanes, police radios, and our LoRa mesh.\nInfrastructure\nInfrastructure refers to the physical and organizational structures and facilities required for the operation of a society or enterprise, such as buildings, roads, and power supplies. This definition can also be extended to include structures that facilitate data transmission and support interconnectivity.\nRadio waves\nRadio waves are a type of electromagnetic radiation that can carry information. They use the longest wavelengths in the electromagnetic spectrum, typically with frequencies of 300GHz or lower. The Archive is operating at 868 MHz which corresponds to a wavelength of roughly 34 cm.\nLilygo T3S3\nESP32-S3 LoRa SX1280 2.4G development board. Contains an ESP32 chip, WIFI, Bluetooth and a LoRa module. Can be connected via serial, Bluetooth or network. Is supported by meshtastic.\nCharacter building\nWe used structured ChatGPT dialogue and local Stable Diffusion for the characters that inhabit our future. Ask the archive for more info about them.\nPrivateGPT\nPrivateGPT is a set of libraries based on llama-index that allow local and offline inference using the computer‘s graphics card. PrivateGPT is particularly good at incorporating local documents. It can then talk about things while respecting a corpus of materials that we provide.\nTranshumanism\nBroadly, the idea that human beings can achieve their next evolutionary step, Human 2.0, through technological advances. Opinions differ as to how this post-human state will be achieved, either through genetic engineering, reverse aging or other technological advances. In our view, it is inspired by Social Darwinism.\nPerception of Infrastructure\nAt its core, infrastructure is an evasive structure. Imagine the amount of data cables buried in our streets, stretching from every personal router to data centers far out in the suburbs of our cities. None of this actual “structure“ is meant to be seen or interacted with until it fails…\nNetwork interface\nWe consider any device that has both user interactivity and Internet/network access to be a network interface.\nEco-Terrorism\nEcotage refers to infrastructure sabotage with ecological goals, while eco-terrorism is even more militant and will use militant strategies with the specific aim of creating terror as a social deterrent.\nPrepping\nPrepping is the act of preparing for the time after the catastrophe, resulting from the belief that current social models will collapse in an apocalyptic manner. Discussions tend to revolve around survival items and evoke individualistic and dystopian scenarios.\nInfrastructure inversion\n“rather than setting out to describe and document all parts of the system that make a footprint possible, the analysis focuses upon a selection of localized sites or issues as suggestive parts of a broader system that is imperceptible in its entirety” (Parks 2009)\nNeo-Religion\nThe Internet, as a network of networks, is such a multifaceted term that it has room for spiritual feelings in the interaction with the network. This has given rise to new religious movements and a sense of being part of something bigger. Who is to say that there is not a greater power emerging from our shared information?\nNeo-Luddism\nNeo-Luddism is a leaderless movement of unaffiliated groups who resist modern technology by passively refraining from using technology, harming those who produce environmentally harmful technology, or sabotaging that technology.\nSub-sea-cables\nCables are often referred to as the backbone of the Internet. Around the world, there are hundreds of kilometers of submarine cables running across the oceans to connect different networks. They are heavy, expensive and buried deep in the sea. Chances are you have never seen one, yet you rely on them every day to deliver information and content.\nOptical fiber cable\nFiber optic cables were developed in the 1980s. The first transatlantic telephone cable to use optical fiber was TAT-8, which went into service in 1988. A fiber optic cable consists of several pairs of fibers. Each pair has one fiber in each direction.\nCopper cable\nCopper is a rare metal and its use contributes to global neo-colonial power structures resulting in a multitude of exploitative practices.\nFor long-distance information transfer, it is considered inferior to Glass fiber cables, due to material expense and inferior weight-to-transfer speed ratio.\nCollapsology\nCollapsology is based on the idea that humans are having a sustained and negative impact on their environment and promotes the concept of an environmental emergency, particularly in relation to global warming and the loss of biodiversity. One potential effect of a collapse is the loss of networks.\nPosthumanism\nIs concerned with the “ongoing deconstruction of humanism” and its premises: humanism’s anthropocentrism, essentialism and speciesism. It is informed by post-anthropocentric ethics, politics, and ecology, and looks toward notions of embodiment and material entanglement between humans and a “more-than-human” world. It emphasizes becoming over being.\n\n"},{"url":"https://aron.petau.net/project/airaspi-build-log/","title":"AIRASPI Build Log","body":"AI-Raspi Build Log\nThis should document the rough steps to recreate airaspi as I go along.\nRough Idea: Build an edge device with image recognition and object detection capabilites.\nIt should be realtime, aiming for 30fps at 720p.\nPortability and usage at installations is a priority, so it has to function without active internet connection and be as small as possible.\nIt would be a real Edge Device, with no computation happening in the cloud.\nInspo from: pose2art\nHardware\n\nRaspberry Pi 5\nRaspberry Pi Camera Module v1.3\nRaspberry Pi GlobalShutter Camera\n2x CSI FPC Cable (needs one compact side to fit pi 5)\nPineberry AI Hat (m.2 E key)\nCoral Dual Edge TPU (m.2 E key)\nRaspi Official 5A Power Supply\nRaspi active cooler\n\nSetup\nMost important sources used\ncoral.ai\nJeff Geerling\nFrigate NVR\nRaspberry Pi OS\nI used the Raspberry Pi Imager to flash the latest Raspberry Pi OS Lite to a SD Card.\nNeeds to be Debian Bookworm.\nNeeds to be the full arm64 image (with desktop), otherwise you will get into camera driver hell.\n{: .notice}\nSettings applied:\n\nused the default arm64 image (with desktop)\nenable custom settings:\nenable ssh\nset wifi country\nset wifi ssid and password\nset locale\nset hostname: airaspi\n\nupdate\nThis is always good practice on a fresh install.

What if cars would could be used as public spaces?\nBy installing a public USB socket and a public wifi hotspot, on my car, I want to start exploring the potential of cars as public spaces and energy storage solutions.\nWithin this artistic experiment, I will continuously track the geolocation and energy input/output of my solar equipped car and make the data publicly available. I will also track the amount of energy that is not used by the car and could be used by the public. Taking steps towards optimal usage of existing electrical and other infrastructure is only possible by breaking conventional notions of public ownership and private property. This project is one step towards a more sustainable and equitable future.\nIntroduction\nWe all know by now that cars and individual traffic presents a major environmetal and societal problem all over the world. The last 70 something years of building car infrastructure are culminating in many areas in a dead end where the only thinkable solution is to build more roads and cars.\nTHis is obviously a larger problem than one project can tackle, but here is one outlook on how\nExperiment\nPreexisting data\nWith the data collected over the last year of using the car privately I can show with embarrasing accuracy how underutilized the system is and calculate an estimate of energy lost due to societal notions of private property.\nThe data will be an estimate, since the monitoring itself is dependent on solar energy and the internet connection is spotty at best when it is not supplied with electricity.\nMonitoring\nIn the Car, there is a Raspberry Pi 4 Microcomputer running a custom Operating Systen that monitors the following data:\n\nSolar Intake (W)\nBattery Level (V)\nGPS Location\nTotal Energy Produced (Wh)\nTotal Energy Consumed (Wh)\nSolar Energy Potential (Wh)\n\nThrough the router I can also track total Wifi usage and the number of connected devices.\nPublic Wifi\nFor the Project, I opened a router in the Car towards the Public, much alike to ahotspot you would find in a cafe. I use my own data plan on there, which I never max out anyways. The router is a Netgear M1 and has a 4G Modem built in. It is connected to the Raspberry Pi and is powered by the secondary car battery.\nPublic Energy: A USB Socket\nI plan on installing a USB Socket on the outside of the car, so people can charge their devices. The socket will be connected to the secondary car battery and will be powered by the solar panels. The socket will be installed in a way that it is not possible to drain the battery completely.\nCommunication\nNobody expects any help or public supplies from car owners.\nHow to communicate the possibility to the outside world?\nThe plan is to fabricate a vinyl sticker that will be applied to the car. The sticker will contain a QR Code that will lead to a website with the data and a short explanation of the project. Visual cues lead to the USB Socket and the Wifi Hotspot.\nIssues\nSpace / Scale\nObviously, the space on top of a car is quite limited and from a sustainability perspective, it would be better to have a larger solar array on a roof of a house. The point is not to advocate for a mandated solar install on cars, but to optimize and share preexisting infrastructure. The car is already there, it already has a battery and it already has solar panels. Looking at many Camper-Van builds, the amount of cars with already installed solar panels is quite large. The point is to make the most out of it.\nLegality\nGermany has laws in place holding the owner of a Internet Connection liable for the legality of the traffic that is going through it. This is a major issue for the project, as I do not want to be liable for the traffic that is going through my car. I am currently looking into ways to circumvent this issue.\nSurveillance / Privacy\nThe Car is equipped with a GPS Tracker and a Wifi Hotspot. This means that I can track the location of the car and the number of devices connected to the hotspot. I am not tracking any data that is going through the hotspot, but I could. As this project will generate public data, People using and maybe depending on the internet and electricity provided will be tracked by proxy. I am not sure how to deal with this issue yet. One potential solution would be to publish the data only in an aggregated form, but this would make the data less useful for other projects.\nSecurity / Safety\nMy Car is now publicly traceable. I am no Elon Musk, and the idea does not really concern me, but we did create an additional attack vector for theft here.\nSources\nUN Sustainable Development Goal Nr. 7\nAdam Something on the Rise of Urban Cars\nIs Berlin a walkable City?\nFBI advising against utilizing public infrastructure\nWhy no solar panels on cars?\n+++\nNotes\nIdeas on Data Mapping workshop\nI have the Solar Data from the Van.\nIt holds Geocodes,\nhas hourly data\nand could tell the difference between geocoded potential solar energy and actual energy.\nIt also has temperature records.\nThere are 2 types of Losses in the system:\n\nEither the Batteries are full and available energy cannot be stored\nOr the solar panels are blocked through urban structures and sub-optimal parking locations.\n\nInteresting Questions:\nHow far away from optimal usage are my panels and where does the difference stem from?\nWhere to go?\nI think, the difference between potential energy and actual electricity produced/consumed is interesting.\nHow large is the gap?\nIs it relevant —> my initial guess would be that it is enormous\nHow to close the gap?\n—> install outside usb plugs\nIt would be publicly available infrastructure, people could charge their smartphones anywhere\n—> QI charging for security concerns??\nScaling??\n—> mandate solar roofs for cars?

Even before \"flatten the curve\" became a common slogan, electrical engineers worried about the small energy spikes in the grid.

Going without emails is unimaginable in today's world, yet most providers are the familiar few from the silicon valley. And really, who wants their entire decentralized, federated, peer-to-peer network to be controlled by a schmuck from the silicon valley? Mails used to be more than that and they can still be.\nArguably, the world of messanging has gotten quite complex since emails popped up and there are more anti-spam AI tools that I would care to count. But the core of it is still the same and it is still a federated system.\nYet, also with Emails, Capitalism has held many victories, and today many emails that are sent from a provider that does not belong to the 5 or so big names are likely to be marked as spam. This is a problem that is not easily solved, but it is a problem that is worth solving.\nAnother issue with emails is security, as it is somehow collectively agreed upon that emails are a valid way to communicate business informations, while Whatsapp and Signal are not. These, at least when talking about messaging services with end-to-end encryption, are likely to be way more secure than emails.\nThe story\nSo it came to pass, that I, as the only one in the family interested in operating it, \"inherited\" the family domain petau.net. All of our emails run through this service, that was previously managed by a web developer that was not interested in the domjobain anymore.\nWith lots of really secure Mail Providers like Protonmail or Tutanota, I went on a research spree, as to how I would like to manage my own service. Soon noticing that secure emails virtually always come with a price or with lacking interoperability with clients like Thunderbird or Outlook, I decided to go for migadu, a swiss provider that offers a good balance between security and usability. They also offer a student tier, which is a big plus.\nWhile self-hosting seems like a great idea from a privacy perspective, it is also quite risky for a service that is usually the only way for any service to recover your password or your online identity.\nMigadu it was then, and in the last three months of basically set it and forget it, i am proud to at least have a decently granular control over my emails and can consciously reflect on the server location of The skeleton service service that enables virtually my entire online existence.\nI certainly crave more open protocols in my life and am also findable on Mastodon, a microblogging network around the ActivityPub Protocol.\n"},{"url":"https://aron.petau.net/project/lusatia/","title":"Lusatia - an immersion in (De)Fences","body":"\n\nOn an Excursion to Lusatia, a project with the Working Title (De)Fences was born.\nHere are the current materials.\n\nTODO: upload unity project\n"},{"url":"https://aron.petau.net/project/autoimmunitaet/","title":"Autoimmunitaet","body":"How do we design our Commute?\nIn the context of the Design and Computation Studio Course Milli Keil, Marla Gaiser and me developed a concept for a playful critique of the traffic decisions we take and the idols we embrace.\nIt should open up questions of whether the generations to come should still grow up playing on traffic carpets that are mostly grey and whether the Letzte Generation, a political climate activist group in Germany receives enough recognition for their acts.\nA call for solidarity.\n\n{: .center}\nThe scan results\n \nThe Action Figure, ready for printing\n \nAutoimmunitaet\nAutoimmunity is a term for defects, that are produced by a dysfunctional self-tolerance of a system.\nThis dysfunction causes the immune system to stop accepting certain parts of itself and build antibodies instead.\nAn invitation for a speculative playful interaction.\n\n\n\n\n\n\nThe Process\nThe figurines are 3D Scans of ourselves, in various typical poses of the Letzte Generation.\nWe used photogrammetry to create the scans, which is a technique that uses a lot of photos of an object to create a 3D model of it.\nWe used the app Polycam to create the scans using IPads and their inbuilt Lidar scanners.\n"},{"url":"https://aron.petau.net/project/dreams-of-cars/","title":"Dreams of Cars","body":"Photography\nIn the context of the course \"Fotografie Elementar\" with Sebastian Herold I developed a small concept of urban intervention.\nThe results were exhibited at the UdK Rundgang 2023 and are also visible here.\n\nDreams of Cars\nThese are not just cars.\nThey are Sport Utility Vehicles.\nWhat might they have had as hopes and dreams on the production line?\nDo they dream of drifting in dusty deserts?\nClimbing steep rocky canyon roads?\nSliding down sun-drenched dunes?\nDiscovering remote pathways in natural grasslands?\nNevertheless, they did end up in the parking spots here in Berlin.\nWhat drove them here?\n\n\n\n\n\n\n\n"},{"url":"https://aron.petau.net/project/stable-dreamfusion/","title":"Stable Dreamfusion","body":"Stable Dreamfusion\n \nSources\nI forked a really popular implementation that reverse engineered the Google Dreamfusion algorithm.

I often struggle to enjoy competitive games and think there is potential in a co-dependent game interface.

For the game, it has an interesting side effect, in that players are forced not only to interact through the differing information on each player's screen but also have to physically interact and coordinate the controls.\nAs you can perhaps see, the ball-rolling navigation is quite hard to use.\nIt is a purely physics-based system, where, depending on the materiality of the ball, its weight, and therefore its inertia will drastically change.\nOn small screens, the prototype version of the game is virtually impossible to control and several visual bugs within the viewport still obfuscate items when they are too close. Considering that virtually all the mechanics are written from scratch, with a follow-me camera, collision detection, smart moving agents, and a still very wonky-looking grappling gun, I still think it deserves a spot in this portfolio.\nFor this project I focused completely on the mechanics of the game, resulting in lots of used prefabs and readymade 3D Objects. Next time, I want to do that myself too.\nI enjoyed my stint into Unity a lot and am looking forward to creating my first VR application and would love to try out some form of mechanics where the user vision is completely obfuscated by VR and they have to carry their eyes as a handheld connected camera so that the players can move around the camera itself with their hands.\n"},{"url":"https://aron.petau.net/project/homebrew/","title":"Homebrew","body":"Brewing\nMaking my own beer\nI love hosting, I love experimenting in the Kitchen.

A bloomery furnace was used to create iron. Making iron requires iron ore and heat under the exclusion of oxygen. It is a highly fragile process that takes an incredible amount of work. The designs and methods vary a lot and were very adapted to the region and local conditions, unlike the much later, more industrialized process using blast furnaces.\nTo this day it is quite unclear how prehistoric people managed to get the amount and quality of iron we know they had.\nThe furnaces that were built were often clay structures and are not preserved. Archeologists often find the leftover burned ore and minerals, giving us some indication of the structure and composition of the ancient furnaces.\nThe group around the ISD takes up a practical archeological approach and we try to recreate the ancient methods with the added capability of maybe sticking temperature probes or electric blowers. Each year we meet up in a different European city and try to adapt to the local conditions, often with local ore and local coal. It is a place where different areas of expertise come together to educate each other while sitting together through the intense day- and night shifts to feed the furnaces.\nSince being a kid, I started building my own furnaces and read up on the process so I could participate.\nTechnology gets a different tint when one is involved in such a process: Even the lights we put up to work through the evening are technically cheating. We use thermometers, meticulously weigh and track the inbound coal and ore, and have many modern amenities around. Yet - with our much more advanced technology, our results are often inferior in quantity and quality in comparison with historical findings. Without modern scales, iron-age people were more accurate and consistent than we are.\nAfter some uncertainty about whether it would take place in 2021 again after it was canceled in 2020, a small group met up in Ulft, Netherlands.\nThis year in Ulft, another group made local coal, so that the entire process was even lengthier, and visitors came from all over to learn about making iron the pre-historic way.\nBelow I captured most of the process in some time-lapses.\nThe Process\n\n\nHere you can see a timelapse of me building a version of an Iron Furnace\nAs you can see, we are using some quite modern materials, such as bricks, this is due to the time constraints of the ISD.\nMaking an oven completely from scratch is a much more lengthy process requiring drying periods in between building.\nAfter, the furnace is dried and heated up\nOver the course of the process, more than 100 kgs of coal and around 20 kgs of ore are used to create a final piece of iron of 200 - 500g, just enough for a single knife.\nWith all the modern amenities and conveniences available to us, a single run still takes more than 3 people working over 72 hours, not accounting for the coal-making or mining and relocating the iron ore.\nSome more impressions from the ISD\n\n\n\n \n \n \n \n \n \n \n \n \n \n a loaded bloomery furnace\n \n \n \n \n \n \n \n \n \n \n \n The ISD from above\n \n \n \n \n \n \n \n \n \n \n \n glowing iron\n \n \n \n \n \n \n \n \n \n \n \n a furnace burning\n \n \n \n \n \n \n \n \n \n \n \n Compacting the resulting iron\n \n \n \n \n \n \n \n \n \n \n \n a heat camera image of the furnace\n \n \n \n \n \n \n \n \n \n \n \n A cross-section illustrating the temperatures reached\n \n \n \n \n\nFor me, it is very hard to define what technology encompasses.

With the struggles our university had transitioning to online teaching, I selected a guided topic, although my initial dream was to start writing about my proposed plan for automated plastic recycling. You can read more about that here:\n\nI chose a project that wanted to examine the possibilities of a novel smart hearing protection device specifically designed for auditory hypersensitivity, which is often, but not always, and not exclusively a phenomenon visible in people with an autism spectrum disorder.\nA common reaction to this elevated sensitivity is stress and avoidance behavior, often leading to very awkward social situations and impairing the ability to take part in social situations.\nSchools are one such social situation and we all know the stress a noisy classroom can produce. Concentration is gone, and education, as well as essential skills like language reproduction, suffer.\nThere is lots of prior research on these fields, and there is some evidence that sensory information in people on the Autism spectrum is processed differently than in a neurotypical brain. It seems that a certain adaptability, needed to overcome noise issues and bridge asynchrony between auditory and visual sensory input, is reduced in some people on the Autism Spectrum.\nIn essence, my experiment was responsible for looking at neurotypical people and measuring any effect on language perception produced by varying the delay between auditory and visual input, as well as the loudness.\nHere, I had the possibility to conduct an entire reaction-time-based experiment with over 70 participants and went through all the struggles that come with proper science.\nI did extensive literature research, coded the experiment, and learned a lot about the reasons nobody really ever does reaction time-based studies like this via a common internet browser.\nIt was an almost 9 months long learning experience full of doing things I had never done before.\nI learned and got to love writing in Latex, had to learn JavaScript for the efficient serving of the stimuli, and R for the statistical analysis. I also got to brush up on my data visualization skills in Python and made some pretty graphs of the results.\nThe experiment is still working and online if you want to have a look at it. Be mindful though that measuring reaction speed every millisecond is important, which is why it makes heavy use of your browser cache and has been known to crash and defeat some not-so-tough computers.\n\n Try out the experiment yourself\n\nEven with writing alone I had extensive helpful feedback from my supervisors and learned a lot about scientific processes and associated considerations.\nThere was always the next unsolvable problem. Just one example was scientificity and ethical considerations clashing, data privacy against the accuracy of results. Since the machines participants participated on, were private devices, I was unable to know important data like their internet speed and provider, their type of GPU, and their type of external hardware. Turns out, for an auditory experiment, the type and setup of the speakers do play an important role and influence response speed.\nThe final version of my thesis has something around 80 pages, much of it utterly boring, but nevertheless important statistical analyses.\nIf you really want to, you can have a look at the whole thing here:\n\n Read the original Thesis\n\nI am a fan and proponent of open source and open science practices.\nSo here you can also find the rest of the project with the original source code.\nI am not yet where I want to be with my documentation practices, and it scares me a bit that anyone can now have a full grasp of all the mistakes I did, but I am throwing this out there as a practice step.

The dangerous argument that the oppressed bear responsibility for their situation is too close for my taste. I would like to emphasize a clear cut between constituting and reinforcing a norm and thriving on it.\nYes, maybe that is a good location to make the cut: The normative and ethical pressure, or better, the guilt of complicity lies with the ones thriving BECAUSE of a norm and clearly not with those thriving DESPITE OF a norm.\nI would think that Butler makes a similar argument elsewhere, but as such, I was missing it here, resulting in a very bleak and hopeless situation where any struggle to change the status quo through legislation is doomed and inevitably propagates and reinvents stable unfair relations of power.\n\n\t\n\t\tNote\n\tcreated by Aron Petau on Sunday 23.

These three logics have the same form: in each case, the rule which serves as a norm, by virtue of which everyone can measure, evaluate, and identify himself or herself, will be derived from those for whom it will serve as a standard.

There is no identity having to undergo some sort of inventive process to start off a collective change, a \"strategy\" just happens to meet the criteria for deployment.\n\nBut between the strategy which fixes, reproduces, multiplies and accentuates existing relations of forces, and the class which thereby finds itself in a ruling position, there is a reciprocal relation of production. Thus one can say that the strategy of moralising the working class is that of the bourgeoisie. One can even say that it's the strategy which allows the bourgeois class to be the bourgeois class and to exercise its domination. But what I don't think one can say is that it's the bourgeois class on the level of its ideology or its economic project which, as a sort of at once real and fictive subject, invented and forcibly imposed this strategy on the working class.\n\nThis was for me the most powerful grasp of what an apparatus is. A complicated removal of the effector from the effect.\nI struggle to continue to find any substance to the relations of the classes. Does reciprocal mean anything more than both are constitutive of each other? One produces the means of reproduction of the other, but where exactly can I apply moral judgements?\nThis whole ordeal and now I lack subjects to blame.\nHow can this theory possibly bring about change in society?

I am incredibly thankful for this methodology of approaching complex philosophical works, often complete books with supplicant essays surrounding the course topic. In my opinion, nearly all of the value created during these seminars is contained within the live discussions fed by reading materials and little opinion pieces in the form of forum comments. That's why I decided to share here a selection of these weekly commentaries and the sources they are based upon. They are often unrefined and informal, but they indicate the centerpiece of the seminars and demonstrate many thought processes that happened within me during these sessions. Although I took only a small selection, in sum they are a substantial read. Feel free to just skip through and read what catches your interest.\nForum entries from the Seminar: Critical Epistemologies\nOn Anderson: Institutions\n\n\t\n\t\tNote\n\tSource Text: Epistemic Justice as a Virtue of Social Institutions\nElizabeth Anderson (2012) Epistemic Justice as a Virtue of Social Institutions, Social Epistemology, 26:2, 163-173,\nDOI: 10.1080/02691728.2011.652211 Publication\n\n\nThe text by Anderson helped shed light on a few issues I stumbled over with Frickers Account. On top of the various issues I and seemingly others have with her virtue-based approach, I think a utilitarian angle is worth considering. That would be: okay, I accept that people can help fight injustice by realising their privilege, showing restraint, silencing themselves, and adopting the benevolent listening approach. I think that is a practical, virtuous, and realistic endeavour.\nBut is it the effective path to alleviating structural injustice? I think not, and initially, that is a major reason I discarded Fricker’s approach, although I saw merit. I have similar concerns to Anderson in the scalability of virtues. Virtuous behavior might help my personal well-being, it gives me normative elevation and might even further the quality of relationships I have. But is it applicable to society, is it enough to counteract structural injustice?\nWell, maybe, assuming that:\n\nEveryone realizes their privilege,\nEveryone concludes that justice is the right goal,\nUpon deciding to adopt a virtuous stance, everyone at least moderately succeeds in practicing what they preach.\n\nI think, for society, the same society that came up with patriarchy in the first place, external pressure, some measure independent of the convictedness of the subjects is needed.\nAnderson made the powerful point of: “Anything that works, goes”, which took me some time to appreciate. I am always angry when I get told to keep my shower to a minimum or stop using plastic straws when I know exactly that my using less water is nothing compared to the institutionalized practice of Coca-Cola putting water into bottles. I feel like it is unjustified to ask me to save water while others triple their output, for performance.\nThe same thing applies to Epistemic injustices. It strikes me how much energy it costs to keep up virtuous behavior individually and how little effect there is to show for it. I do not believe in “trickling up” where institutions will eventually adopt individual practices.\nIs Fricker thereby less right in her point? No, it adds up, as an entire population showering shorter adds up to lots of water saved.\nAnderson also points out how locally innocent biases can create injustice on a “macro” scale. Another indicator for me is that local virtue is not the sole solution, as it can still feed and sustain a system enforcing epistemic injustice.\nI still have doubts about what to do now with my ideas, on how the world looks that I want. I lack the imagination of seeing a world that is epistemically just, and it is hard to strive for something one cannot even imagine. The system is inherently leaning toward inequality, if I try to balance something on a needle, it will only go well so long, before small imbalances create chain reactions and the object should be called unstable. Should we even succeed in “resetting” society, creating equal participation for each subject, how will it remain just? Is Justice always a conjunct of Equality? Are there ways to achieve real Justice without needing equality?\n\n\t\n\t\tNote\n\tcreated by Aron Petau on Tuesday 14. July 2020, 17:45\n\n\nOn Medina, the informant and the inquirer\n\n\t\n\t\tNote\n\tSource Text: Dr. José Medina (2012) Hermeneutical Injustice and Polyphonic Contextualism: Social Silences and Shared Hermeneutical Responsibilities, Social Epistemology, 26:2, 201-220, DOI: 10.1080/02691728.2011.652214\nPublication\n\n\nMy biggest takeaway here was that, as I tried to hint at in an earlier comment,\nWhenever we talk about justice, this necessarily refers to a relational concept, where everybody has a double role to ensure successful communication. Medina calls these the inquirer and the informant. So, every individual has to make sure to act to her capacity as an epistemologically sound knowledge-acquiring agent (the inquirer). This would involve knowing when and how to falsify/qualify statements, making inferences about the theory of mind, and generally comparing different statements. The other role is the informant, where the individual should have the capacity to function as an object in an inquiry by another.\nVery roughly this can, I think, be compared to any good communication model, where there are a listener and a speaker, and both have to function. What was new here, or at least came out more clear is that it not only depends on the capacity of both of these roles on the subject, but it is also directly dependent on the “other”, the agent opposite of the subject. We may call this other society later but it helps me to visualize the other as an individual nonetheless. Where the analogy to communication now fails, in my opinion, is this cross-dependence, where an agent does not fully determine her capacity to act both as an inquirer and as an informant, it is co-determined by the “other”. So, if I, as an “other”, listen to someone's statements, and I fail or refuse to understand the epistemic content of the message, I am not only impairing my epistemic agency, but I also hurt the epistemic agency of the subject. Maybe obvious to most, but this thought struck me as being exactly the point of leverage for dysfunctionalities in power relations.\nAlso argued convincingly in the paper was that these are distinct and independent agencies, which can be impairing an individual separately.\nOverall, the Medina text was incredibly helpful after the somewhat confusing Fricker text that felt incomplete and left a lot of questions for me. The medina text picked up all my initial doubts, that I couldn't properly formulate, and many more, while still holding to the general framework of Fricker.\nAlthough I was not convinced by the Fricker Text, I tend to think the strategy:\n\"When in doubt, give the subject full epistemic credibility\"\nIs a good strategy that might alleviate a lot of issues regarding functions of power, and hierarchy, but also further, it might be a good counter for things as our confirmation bias, expectation bias and many individual errors that we could minimize by constantly exposing ourselves to falsifiability through others (voluntarily). Sounds like science applied to agency to me.\n\n\t\n\t\tNote\n\tcreated by Aron Petau on Thursday 09.

Jaggar (1989) Love and knowledge: Emotion in feminist epistemology, Inquiry, 32:2, 151-176, DOI: 10.1080/00201748908602185\nPublication\n\n\nI found Jaggar to be a very wholesome read, it was the perfect amount of grounded argumentative structure and felt very connected as a whole. This was, together with the ideas from Lugones the best and most fruitful paper for me.\nOn outlaw emotions:\nFirst, I hate the term, I think it’s placative and fails to frame the (actually nice) idea behind it.\nOutlaw Emotions are all those emotions incompatible with the dominant norms. That’s a huge field to cover, among feminist emotions they would also encompass emotions that are irrational or “faulty”. So, Jaggar does the term Justice by saying, some, but not all Outlaw Emotions are Feminist emotions. To make this evident, just think of a murderer's joy for killing, it is of no feminist interest to dissect, yet it is against dominant values. So, experiencing Outlaw emotions is a (probably) necessary, but not sufficient condition for feminism. The incompatible emotion serves to create discourse and change.\nJaggar convincingly shows how emotions have a direct influence on beliefs and can validly constitute evidence, while simultaneously validly influencing values in a similar manner.\nWhen we talk about dominant/alternative norms, we already endorse hierarchy in society. We acknowledge its existence, simply by identifying the dominant norm. I am not quite sure what exactly Jaggar proposes we should do with the hierarchy structures in society. Explicitly I can read: Subcultures rejecting dominant norms should be formed, to create counterbalances and a somewhat fair discourse over the topic.\n“How can we determine which outlaw emotions are to be endorsed or encouraged and which rejected? In what sense can we say that some emotional responses are more appropriate than others? What reason is there for supposing that certain alternative perceptions of the world, perceptions informed by outlaw emotions, are to be preferred to perceptions informed by conventional emotions? Here I can indicate only the general direction of an answer, whose full elaboration must await another occasion. I suggest that emotions are appropriate if they are characteristic of a society in which all Human Life (and perhaps some nonhuman life, too) thrive, or if they are conducive to establishing such a society.”\nTo me this passage sounds sketchy at best, there is no indication of how to successfully separate appropriate from inappropriate emotions. Roughly, I read this part as: emotions are warranted iff they increase the balance of power. (equivalent to minimizing the height of the hierarchy) I would love to get to read this “other occasion” because it seems indefensible to me to formulate a norm that states: Accept only emotions which eliminate/diminish norms.\nThe idea roughly resembles Rawls's Minimax Principle, where a policy should be implemented iff the benefit for the most disadvantaged is highest.\nAnother thing I found helpful is her reformulation of what norms do:\n“Dominant Norms tend to serve dominant interests”\ntil here nothing new, this is a tautology for me, I understand norms as identical to dominant interests, that’s literally what norms are.\nIs an alternative, suppressed norm even thinkable? Isn't it inherent in a norm that it be the dominant one?\nBut then, after that: \"Whatever our color / gender / class / sexual orientation, we are likely to adopt the dominant value of racist, classist, homophobe, misogynistic white men.\"\nThis was rather helpful to me, as it reframes the “act” of oppression as the “likelihood of value distribution” being skewed in your favor, making everybody’s values more likely to be similar to yours. This nicely illustrates how a system can be hierarchical and oppressive, without anybody actively, intentionally “acting oppressive”, while still perpetuating oppression. I'm\nnot saying everybody is acting unintentionally oppressive, but it is always hard to imagine for me to picture \"White Men\" forming a group and collectively deciding on who to hate this coming season, Conceptually separating \"being oppressed\" and \"oppressing\" into phenomena\nwithout necessary inherent causal relation makes sense to me here.\n\n\t\n\t\tNote\n\tcreated by Aron Petau on Tuesday 23.

Se défendre: une philosophie de la violence. Zones, 2017.\nPublication (Not yet translated to English)\n\n\nFrom the seventh chapter in Dorlins \"Self-Defense\", I found the idea that safe spaces are actually prone to be counterproductive very strong.\nI think the discussion around whether safe spaces are an effective tool that is appropriate on top is a rather current and ongoing one.\nIn so many other words, Dorlin here opens up the idea that the creation of a safe space always implies a hostile \"outside\" or other space.\nFurther, Dorling sees as problematic that safe spaces will often experience problematic situations when trying to self-govern. The line of thought here is that safe spaces often explicitly reject the authority of traditional state bodies, since those exactly are identified as the oppressive force. This is problematic because then the community inside the safe space has to recreate social norms from scratch and qua definition of a safe space end up being much more restrictive and monitoring, tapping also into potentially extreme measurements for \"enforcing\" safety.\nDorlin notes that by doing this, societal oppressive norms can end up becoming reproduced through the very instance created to shelter from it.\nI think this opens up 2 points worth discussing:\nAre there limits to the self-governance of leftist groups? How can self-governance be made possible without recreating some hierarchy or other?\nDoes this ignore that safe spaces can sometimes be essential for survival? According to Dorlin, the alternative seems to be to instead of building sheltered, isolated safe spaces, the fight has to occur in the public, transforming the entire space without the necessity for exclusive logic. How can we argue this? Could there be an oppressed position from whence any aggressive stance towards the public forbids itself? (I think there is!) For me this seems like putting the entire burden of transformational potential on the oppressed individual, enabling a position like: \"Well, the person did not object or introduce change, so the person implied consent.\"\nWill a public fight cause more harm being fought than it will save after introducing change? And who are we to calculate this beforehand?\n\n\t\n\t\tNote\n\tcreated by Aron Petau on Sunday 05.

Epistemic injustice: Power and the ethics of knowing. Oxford University Press, 2007.\nPublication\n\n\n\nWorin unterscheiden sich inferentialistische von nicht-inferentialistischen Theorien der testimonialen Erkenntnis (d.h. des Wissens durch das Zeugniss andere)?\n\nInferentialistische Theorien gehen davon aus, dass die eigentliche Inferenz, also die Generierung eines neuen Epistems im Subjekt stattfindet. Konkret heisst dass, dass Ich die Aussage P einer dritten Person erst in irgendeiner Weise vor mir selbst rechtfertigen muss, bevor ich sie selbst verwenden kann. Ist die Aussage nun 2 + 2 = 4, muss ich also mit allen mir zur Verfügung stehenden Mitteln selbst überprüfen, ob diese Aussage Wahrheits- und Kohärenzkriterien erfüllt. Ich muss also beispielsweise über darunterliegende Axiome, die mir bekannt sind, die Aussage extern (ausserhalb von Person X hat das gesagt, also kann Ich das glauben) überprüfen. Im simplen Beispiel also konkret das Ergebnis berechnen. Wenn man so will, liegt also immer die “Beweislast” für meine eigenen Episteme bei mir und ich kann diesen Beweisaufwand nur begrenzt auslagern. Eine sehr direkte Folge davon wäre, dass jeglicher Erkenntnisgewinn mit erheblicher, bewusster oder unbewusster Arbeit verbunden ist.\nDies wäre die wahrscheinlich logisch stringentere Theorie, gegen sie spricht aber die Phänomenologie eines Erkenntisgewinns. Eine Erkenntnis kommt uns oft vor wie ein “Heureka” Moment, wir “finden” sie, plötzlich ist sie da und wir können mit ihr arbeiten.\nEine nicht-inferentialistische Theorie legt ebendiese Beweislast nicht im Subjekt an, ich habe eine Erlaubnis, oder besser, ein Recht auf a-priori Annahme der Richtigkeit der Aussage. “Person X hat mir P gesagt, also kann ich P verwenden” ist nun valide und bedarf erstmal keiner weiteren Überprüfung auf Richtigkeit. Diese Argumentationslinie ist deutlich kompatibler mit der phänomenologischen Erfahrung einer Erkenntnis vim Alltag. Wir stoßen aber auf deutlich größere Probleme, wenn wir uns fragen, woher eigentlich unser Recht auf Wahrheitsannahme von Drittaussagen kommt. Klar, 2+2=4, weil der Prof das an die Tafel geschrieben hat, ist die “schlechtere” Begründung als zu sagen, dass das Ergebnis aus gewissen mathematischen Axiomen deduziert wurde.\n\nFormulieren Sie jeweils einen Einwand gegen beide Theorien.\n\nWir befinden uns also nun in der Spannung der phänomenalistischen “Heureka” Erfahrung des Findens von Epistemen (in nicht-inferentiellen Systemen) und dem Problem der schwachen Justifizierung von Aussagen gegenüber der erhöhten Stringenz eines epistemischen Systems, dass externe (logische, probabilistische, normative etc.) Gründe für Aussagen zur Verfügung stellt, aber einen schier unüberwindbaren rechnerischen Aufwand darstellt. Auch das Problem der ersten Begründung bleibt bestehen.

Reading Judith Butler and Elsa Dorlin\nOn Dorlin\n\n\t\n\t\tNote\n\tSource Text: Dorlin, Elsa. Se défendre: une philosophie de la violence. Zones, 2017.\nPublication (Not yet translated to English)\n\n\nFrom the seventh chapter in Dorlins \"Self-Defense\", I found the idea that safe spaces are actually prone to be counterproductive very strong.\nI think the discussion around whether safe spaces are an effective tool that is appropriate on top is a rather current and ongoing one.\nIn so many other words, Dorlin here opens up the idea that the creation of a safe space always implies a hostile \"outside\" or other space.\nFurther, Dorling sees as problematic that safe spaces will often experience problematic situations when trying to self-govern. The line of thought here is that safe spaces often explicitly reject the authority of traditional state bodies, since those exactly are identified as the oppressive force. This is problematic because then the community inside the safe space has to recreate social norms from scratch and qua definition of a safe space end up being much more restrictive and monitoring, tapping also into potentially extreme measurements for \"enforcing\" safety.\nDorlin notes that by doing this, societal oppressive norms can end up becoming reproduced through the very instance created to shelter from it.\nI think this opens up 2 points worth discussing:\nAre there limits to the self-governance of leftist groups? How can self-governance be made possible without recreating some hierarchy or other?\nDoes this ignore that safe spaces can sometimes be essential for survival? According to Dorlin, the alternative seems to be to instead of building sheltered, isolated safe spaces, the fight has to occur in the public, transforming the entire space without the necessity for exclusive logic. How can we argue this? Could there be an oppressed position from whence any aggressive stance towards the public forbids itself? (I think there is!) For me this seems like putting the entire burden of transformational potential on the oppressed individual, enabling a position like: \"Well, the person did not object or introduce change, so the person implied consent.\"\nWill a public fight cause more harm being fought than it will save after introducing change?

Oxford University Press, 2007.\nPublication\n\n\n\nWorin unterscheiden sich inferentialistische von nicht-inferentialistischen Theorien der testimonialen Erkenntnis (d.h. des Wissens durch das Zeugniss andere)?\n\nInferentialistische Theorien gehen davon aus, dass die eigentliche Inferenz, also die Generierung eines neuen Epistems im Subjekt stattfindet. Konkret heisst dass, dass Ich die Aussage P einer dritten Person erst in irgendeiner Weise vor mir selbst rechtfertigen muss, bevor ich sie selbst verwenden kann. Ist die Aussage nun 2 + 2 = 4, muss ich also mit allen mir zur Verfügung stehenden Mitteln selbst überprüfen, ob diese Aussage Wahrheits- und Kohärenzkriterien erfüllt. Ich muss also beispielsweise über darunterliegende Axiome, die mir bekannt sind, die Aussage extern (ausserhalb von Person X hat das gesagt, also kann Ich das glauben) überprüfen. Im simplen Beispiel also konkret das Ergebnis berechnen. Wenn man so will, liegt also immer die “Beweislast” für meine eigenen Episteme bei mir und ich kann diesen Beweisaufwand nur begrenzt auslagern. Eine sehr direkte Folge davon wäre, dass jeglicher Erkenntnisgewinn mit erheblicher, bewusster oder unbewusster Arbeit verbunden ist.\nDies wäre die wahrscheinlich logisch stringentere Theorie, gegen sie spricht aber die Phänomenologie eines Erkenntisgewinns. Eine Erkenntnis kommt uns oft vor wie ein “Heureka” Moment, wir “finden” sie, plötzlich ist sie da und wir können mit ihr arbeiten.\nEine nicht-inferentialistische Theorie legt ebendiese Beweislast nicht im Subjekt an, ich habe eine Erlaubnis, oder besser, ein Recht auf a-priori Annahme der Richtigkeit der Aussage. “Person X hat mir P gesagt, also kann ich P verwenden” ist nun valide und bedarf erstmal keiner weiteren Überprüfung auf Richtigkeit. Diese Argumentationslinie ist deutlich kompatibler mit der phänomenologischen Erfahrung einer Erkenntnis vim Alltag. Wir stoßen aber auf deutlich größere Probleme, wenn wir uns fragen, woher eigentlich unser Recht auf Wahrheitsannahme von Drittaussagen kommt. Klar, 2+2=4, weil der Prof das an die Tafel geschrieben hat, ist die “schlechtere” Begründung als zu sagen, dass das Ergebnis aus gewissen mathematischen Axiomen deduziert wurde.\n\nFormulieren Sie jeweils einen Einwand gegen beide Theorien.\n\nWir befinden uns also nun in der Spannung der phänomenalistischen “Heureka” Erfahrung des Findens von Epistemen (in nicht-inferentiellen Systemen) und dem Problem der schwachen Justifizierung von Aussagen gegenüber der erhöhten Stringenz eines epistemischen Systems, dass externe (logische, probabilistische, normative etc.) Gründe für Aussagen zur Verfügung stellt, aber einen schier unüberwindbaren rechnerischen Aufwand darstellt.

Sadly, we used beta functionality from the older \"Google Assistant\" Framework, which got rebranded months after by Google into \"Actions on Google\" and changed core functionality requiring extensive migration that neither Chris, my partner in this project, nor I found time to do.\nNevertheless, the whole Chatbot functioned as a meditation player and was able to graph and store recorded sentiments over time for each user.\nAttached below you can also find our final report with details on the programming and thought process.\n\n Read the full report\n\n\n Look at the Project on GitHub\n\n\n\t\n\t\tNote\n\tAfter this being my first dip into using the Google Framework for the creation of a speech assistant and encountering many problems along the way that partly found their way also into the final report, now I managed to utilize these explorations and am currently working to create Ällei, another chatbot with a different focus, which is not realized within Actions on google, but will rather be getting its own react app on a website.\n\n\n"},{"url":"https://aron.petau.net/project/critical-epistemologies/","title":"Critical Epistemology","body":"Forum entries from the Seminar: Critical Epistemologies\nOn Anderson: Institutions\n\n\t\n\t\tNote\n\tSource Text: Epistemic Justice as a Virtue of Social Institutions\nElizabeth Anderson (2012) Epistemic Justice as a Virtue of Social Institutions, Social Epistemology, 26:2, 163-173,\nDOI: 10.1080/02691728.2011.652211 Publication\n\n\nThe text by Anderson helped shed light on a few issues I stumbled over with Frickers Account. On top of the various issues I and seemingly others have with her virtue-based approach, I think a utilitarian angle is worth considering. That would be: okay, I accept that people can help fight injustice by realising their privilege, showing restraint, silencing themselves, and adopting the benevolent listening approach. I think that is a practical, virtuous, and realistic endeavour.\nBut is it the effective path to alleviating structural injustice? I think not, and initially, that is a major reason I discarded Fricker’s approach, although I saw merit. I have similar concerns to Anderson in the scalability of virtues. Virtuous behavior might help my personal well-being, it gives me normative elevation and might even further the quality of relationships I have. But is it applicable to society, is it enough to counteract structural injustice?\nWell, maybe, assuming that:\n\nEveryone realizes their privilege,\nEveryone concludes that justice is the right goal,\nUpon deciding to adopt a virtuous stance, everyone at least moderately succeeds in practicing what they preach.\n\nI think, for society, the same society that came up with patriarchy in the first place, external pressure, some measure independent of the convictedness of the subjects is needed.\nAnderson made the powerful point of: “Anything that works, goes”, which took me some time to appreciate. I am always angry when I get told to keep my shower to a minimum or stop using plastic straws when I know exactly that my using less water is nothing compared to the institutionalized practice of Coca-Cola putting water into bottles. I feel like it is unjustified to ask me to save water while others triple their output, for performance.\nThe same thing applies to Epistemic injustices. It strikes me how much energy it costs to keep up virtuous behavior individually and how little effect there is to show for it. I do not believe in “trickling up” where institutions will eventually adopt individual practices.\nIs Fricker thereby less right in her point? No, it adds up, as an entire population showering shorter adds up to lots of water saved.\nAnderson also points out how locally innocent biases can create injustice on a “macro” scale. Another indicator for me is that local virtue is not the sole solution, as it can still feed and sustain a system enforcing epistemic injustice.\nI still have doubts about what to do now with my ideas, on how the world looks that I want. I lack the imagination of seeing a world that is epistemically just, and it is hard to strive for something one cannot even imagine. The system is inherently leaning toward inequality, if I try to balance something on a needle, it will only go well so long, before small imbalances create chain reactions and the object should be called unstable. Should we even succeed in “resetting” society, creating equal participation for each subject, how will it remain just? Is Justice always a conjunct of Equality? Are there ways to achieve real Justice without needing equality?\n\n\t\n\t\tNote\n\tcreated by Aron Petau on Tuesday 14. July 2020, 17:45\n\n\nOn Medina, the informant and the inquirer\n\n\t\n\t\tNote\n\tSource Text: Dr. José Medina (2012) Hermeneutical Injustice and Polyphonic Contextualism: Social Silences and Shared Hermeneutical Responsibilities, Social Epistemology, 26:2, 201-220, DOI: 10.1080/02691728.2011.652214\nPublication\n\n\nMy biggest takeaway here was that, as I tried to hint at in an earlier comment,\nWhenever we talk about justice, this necessarily refers to a relational concept, where everybody has a double role to ensure successful communication. Medina calls these the inquirer and the informant. So, every individual has to make sure to act to her capacity as an epistemologically sound knowledge-acquiring agent (the inquirer). This would involve knowing when and how to falsify/qualify statements, making inferences about the theory of mind, and generally comparing different statements. The other role is the informant, where the individual should have the capacity to function as an object in an inquiry by another.\nVery roughly this can, I think, be compared to any good communication model, where there are a listener and a speaker, and both have to function. What was new here, or at least came out more clear is that it not only depends on the capacity of both of these roles on the subject, but it is also directly dependent on the “other”, the agent opposite of the subject. We may call this other society later but it helps me to visualize the other as an individual nonetheless. Where the analogy to communication now fails, in my opinion, is this cross-dependence, where an agent does not fully determine her capacity to act both as an inquirer and as an informant, it is co-determined by the “other”. So, if I, as an “other”, listen to someone's statements, and I fail or refuse to understand the epistemic content of the message, I am not only impairing my epistemic agency, but I also hurt the epistemic agency of the subject. Maybe obvious to most, but this thought struck me as being exactly the point of leverage for dysfunctionalities in power relations.\nAlso argued convincingly in the paper was that these are distinct and independent agencies, which can be impairing an individual separately.\nOverall, the Medina text was incredibly helpful after the somewhat confusing Fricker text that felt incomplete and left a lot of questions for me. The medina text picked up all my initial doubts, that I couldn't properly formulate, and many more, while still holding to the general framework of Fricker.\nAlthough I was not convinced by the Fricker Text, I tend to think the strategy:\n\"When in doubt, give the subject full epistemic credibility\"\nIs a good strategy that might alleviate a lot of issues regarding functions of power, and hierarchy, but also further, it might be a good counter for things as our confirmation bias, expectation bias and many individual errors that we could minimize by constantly exposing ourselves to falsifiability through others (voluntarily). Sounds like science applied to agency to me.\n\n\t\n\t\tNote\n\tcreated by Aron Petau on Thursday 09.

Jaggar (1989) Love and knowledge: Emotion in feminist epistemology, Inquiry, 32:2, 151-176, DOI: 10.1080/00201748908602185\nPublication\n\n\nI found Jaggar to be a very wholesome read, it was the perfect amount of grounded argumentative structure and felt very connected as a whole. This was, together with the ideas from Lugones the best and most fruitful paper for me.\nOn outlaw emotions:\nFirst, I hate the term, I think it’s placative and fails to frame the (actually nice) idea behind it.\nOutlaw Emotions are all those emotions incompatible with the dominant norms. That’s a huge field to cover, among feminist emotions they would also encompass emotions that are irrational or “faulty”. So, Jaggar does the term Justice by saying, some, but not all Outlaw Emotions are Feminist emotions. To make this evident, just think of a murderer's joy for killing, it is of no feminist interest to dissect, yet it is against dominant values. So, experiencing Outlaw emotions is a (probably) necessary, but not sufficient condition for feminism. The incompatible emotion serves to create discourse and change.\nJaggar convincingly shows how emotions have a direct influence on beliefs and can validly constitute evidence, while simultaneously validly influencing values in a similar manner.\nWhen we talk about dominant/alternative norms, we already endorse hierarchy in society. We acknowledge its existence, simply by identifying the dominant norm. I am not quite sure what exactly Jaggar proposes we should do with the hierarchy structures in society. Explicitly I can read: Subcultures rejecting dominant norms should be formed, to create counterbalances and a somewhat fair discourse over the topic.\n“How can we determine which outlaw emotions are to be endorsed or encouraged and which rejected? In what sense can we say that some emotional responses are more appropriate than others? What reason is there for supposing that certain alternative perceptions of the world, perceptions informed by outlaw emotions, are to be preferred to perceptions informed by conventional emotions? Here I can indicate only the general direction of an answer, whose full elaboration must await another occasion. I suggest that emotions are appropriate if they are characteristic of a society in which all Human Life (and perhaps some nonhuman life, too) thrive, or if they are conducive to establishing such a society.”\nTo me this passage sounds sketchy at best, there is no indication of how to successfully separate appropriate from inappropriate emotions. Roughly, I read this part as: emotions are warranted iff they increase the balance of power. (equivalent to minimizing the height of the hierarchy) I would love to get to read this “other occasion” because it seems indefensible to me to formulate a norm that states: Accept only emotions which eliminate/diminish norms.\nThe idea roughly resembles Rawls's Minimax Principle, where a policy should be implemented iff the benefit for the most disadvantaged is highest.\nAnother thing I found helpful is her reformulation of what norms do:\n“Dominant Norms tend to serve dominant interests”\ntil here nothing new, this is a tautology for me, I understand norms as identical to dominant interests, that’s literally what norms are.\nIs an alternative, suppressed norm even thinkable? Isn't it inherent in a norm that it be the dominant one?\nBut then, after that: \"Whatever our color / gender / class / sexual orientation, we are likely to adopt the dominant value of racist, classist, homophobe, misogynistic white men.\"\nThis was rather helpful to me, as it reframes the “act” of oppression as the “likelihood of value distribution” being skewed in your favor, making everybody’s values more likely to be similar to yours. This nicely illustrates how a system can be hierarchical and oppressive, without anybody actively, intentionally “acting oppressive”, while still perpetuating oppression. I'm\nnot saying everybody is acting unintentionally oppressive, but it is always hard to imagine for me to picture \"White Men\" forming a group and collectively deciding on who to hate this coming season, Conceptually separating \"being oppressed\" and \"oppressing\" into phenomena\nwithout necessary inherent causal relation makes sense to me here.\n\n\t\n\t\tNote\n\tcreated by Aron Petau on Tuesday 23.

All of this leads to a huge industry, Germany being especially involved, using loads of virgin plastic.\nWhat can be done about it?\nWe can design our products to last longer, we can also print recycling labels on them so they do not have to get burned after their first life. We can take care to only print functional objects, not just fun toys nobody uses.\nYet, none of that prevents the use of virgin plastics. If you buy a spool of filament, there are some recycled options, but usually at twice the price at worse quality. No wonder recycled filament fails to convince the masses. It is mostly a fun thing YouTubers can pursue, not a valid commercial process.\n\n\nIn my opinion, the core problem is the nonexistent economic feasibility of a proper recycling process. Identifying the exact material of a piece of trash is a very hard problem, definitely not solved yet. So why do we mix the plastic up in the first place? There is a general willingness of people to recycle, but the system for it is missing.\nThe Master Plan\nI want to get people to wash and separate their trash for me, which are the most expensive steps in the recycling process. There is a willingness to take the extra step, and even if just my mom collects bottle caps for me, that is more than I can realistically use up.\nThis only really works when I am thinking in a local and decentral environment.\nThe existing recycling facilities clearly will not be able to provide 200 different containers for 200 different types of plastic.\nStarting the process with clean and sorted materials, like bottle caps (HDPE) or failed prints (PET-G), I start off with an advantage.\nNow I have to take apart the trash into evenly sized particles.\nMeet:\nThe Shredder\nWe built the Precious Plastic Shredder!\n\nWith these awesome open-source drawings, I was able to cobble together my very own very dangerous plastic shredder.\nAfter finding some way to drive this massive axis, I feed the beast and hopefully get tiny pretty uniform plastic bits that are ready to begin the cycle of life anew.\nThe solution for the motorization was an old and used garden shredder that still had an intact motor and wiring.\nWe cut it in half and attached it to the shredder box.\n\n\nAfter replacing the weak force transmission screw for an industrial coupler, we were ready to try it out. Obviously, there are still security concerns in this prototype, a proper hopper is already being made.\nNevertheless, we are confident that this shredder will be able to deal with the light sorts of plastic we are thinking of.\nAs you can see, I am now able to produce awesome confetti but to do more with the plastic flakes I have to extrude them.\nMeet the Filastruder\nThis is the Filastruder, designed and made by Tim Elmore, in an attempt to create the cheapest viable way to extrude plastic. The biggest cost issue is the tight industrial tolerances in thickness that have to be adhered to. This is in essence what separates good from the bad filament. The industry standard nowadays is at +-0.03mm. Hard to achieve on a DIY setup, but not unheard of. The setup, like any bigger industry equivalent, consists of a motor pressing plastic pellets through a heated screw, extruding molten plastic at the end through a nozzle, and setting the diameter. The leftmost machine is responsible for winding the filament properly onto a spool.\nHere you can see the extrusion process in action.\n\n\nThe Filastruder is controlled by an Arduino and is highly configurable. The laser sensor visible in the video is already working, but I am missing more direct control over the diameter of the filament.\nWhen it all really comes down to the single variable of the filament diameter responsible for the quality of my recycled project, a simple Machine Learning optimization directly jumps at me: I have a few variables like winder speed, extrusion speed, heat, and cooling intensity. These variables can be optimized on the fly for an exact diameter. This is actually roughly how virgin filament is produced, commercial facilities just manage much faster.\n\nSo far, I am aware of a few companies and academic projects attempting this process, but none of them manage to get either the quality or the price of other products available. Automatization does not just take out jobs away, I think it can also be a helpful tool, for example tackling environmental issues such as this one.\nThis project is very dear to my heart and I plan to investigate it further in the form of a master thesis.\nThe realization will require many skills I am already picking up or still need to work on within the Design and Computation program.\n{: .notice--info}\n\n Reflow Filament\n\n\n Perpetual Plastic Project\n\n\n Precious Plastic Community\n\n\n Filamentive Statement on why recycling is not feasible in their opinion\n\n\n Open source filament diameter sensor by Tomas Sanladerer\n\n\n Re-Pet Shop\n\n"},{"url":"https://aron.petau.net/project/beacon/","title":"BEACON","body":"BEACON: Decentralizing the Energy Grid in inaccessible and remote regions\nAccess to Electricity is a basic human right. At first, that may seem over the top, but if one stops to think what all the little tasks that electricity can indirectly handle for us (lightning, laundry, cooking, freezing, heating, entertaining…) would consume in time and effort if we had to perform them manually, this idea becomes very clear. There are globally around 1 billion people without tier 2 access to electricity.\nSDGS Goal 7\n\nPeople only know the intensity of labor that goes into everything when there is no electricity. And it is not even only about convenience, electricity is an enormous lifesaver in any number of scenarios, think just of hospitals or mobile phone networks that would be rendered completely useless without it. So we can easily agree on a need, a demand for electricity globally, for every person. But what about the supply? Why is there 1 billion undersupplied?\nThe Answer: missing profitability. It would be a charity project to supply every last person on earth, not a profitable one. And while charitable projects are noble and should be pursued, the reality within capitalism shows that this is not the way it is going to happen.\nBut what if we could come up with technology, or rather, a communal structure, that enables us to supply profitably, and still adapt to both, the difficult external factors (weather issues, remoteness, altitude, etc.) and the smaller purses of the undersupplied?\nLocation\nTowards the end of 2018, I spent 4 months in northern India, on a research project with the IIT Kharagpur.\nThe goal was to work on one of the 17 UN-defined sustainable development goals – electricity.\nWorldwide, an estimated 1 billion people have no or insubstantial access to the grid.\nSome of them live here, in the Key Monastery in the Spiti Valley at around 3500 meters altitude.\n\n\n\nThis is Tashi Gang, a village close to the Monastery. It houses around 50 people and only has road access during 3-4 months in the summer. For the rest of the time, the people rely on first aid services by helicopter, which can only be called with a working cell phone tower.\n\nThe Project\nIn an environment reliant on hydro-energy and solar (diesel transport is unreliable due to snowed-in mountain roads), over 6 months of snowy winter, frequent snowstorms, and temperatures of up to -35°C, securing the grid is hard.\nOur way to tackle the issue was to reject the in the western society very established notion of electricity as a homogenous product with centralized production and instead researched the possibilities of a predictive, self-correcting, and decentral grid.\nBy prioritizing energy usage cases, instead of a full blackout during a storm, essential functions like radio towers and hospitals could be partially powered and maybe stay functioning. The binarity of either having electricity or not would be replaced by assigned quantities and timeslots, in a collective effort to be mindful and distribute the electricity necessity-based.\nThe ultimate vision was a live predictive electricity market, where people could even earn money by selling their allotted, but not needed electricity.\nTo gauge feasibility, I conducted several psychological acceptance studies and collected data on local electricity demands.\nI simulated a typical day of electricity demand in the Key monastery and the surrounding villages and mapped out the potential to install cost-efficient smart microgrid controllers enabling such an accurate and predictive behavior.\nThe smart grid operator boxes available here in Germany cost several hundred, with installation several thousand Euros, not a feasible solution for the Indian population. Instead, we wanted to use Raspberry Pi's, which are interconnected through ethernet cables or local mesh networking.\nResearch\n\nData Collection\nBuilding a questionnaire and visiting public schools during their English Classes, I had the chance to speak to a range of teenagers, answering questions about the state of electricity in their homes, generating more data than I could have accomplished running from door to door without any skills speaking local dialects. The questionnaire was as scientific as I could make it in such a situation and geared towards finding the type and number of electric devices in the homes and estimating typical usage scenarios.\nWith a total of 145 participants from more than 6 different schools and roughly 4 different districts, all located in the Indian part of the Himalayas, the findings are as follows:\nThe participants range from 11 to 53 years, with an average of 17 years.\nThe average household has 6 members with an average of 5 smart devices. Only 2 percent of the Households had not a single smart device, but at the same time, only 42 percent had direct or indirect access to a laptop or computer. So the main body of smart devices consists of smartphones with a negligible portion of tablets.\nThe average total amount of electrical devices is around 11 electrical appliances per house.\nSubjective Quality Rating on a scale of 1 to 10:\n\nAverage quality in summer: 7.1\nAverage quality in monsoon: 5.6\nAverage quality in autumn: 7.1\nAverage quality in winter: 4.0\n\nSo, as you would expect, during winter, but also when it rains, the felt quality drops by more than 30 percent on average.\nAs for the daily supply time, the average sits at 15.1 hours out of 24, meaning the people have electricity only for 62.9 percent of the time, some, as for example the people in Diskit only have a sad 4 hours of daily access. On top of that, this estimation does not account for the snowfalls in Spiti for example, where it is not uncommon to experience 3 consecutive days of powercut or more.\nAs the Power Meter is supplied by the government, a solid 82 percent of the houses have a working power meter, if one assumes that the 13 percent who did not know whether they have a power meter, do have one, we can say that around 95% of the houses have a power meter.\nAnother goal of the studies was to find out what would incline people to be caring and sharing with the available electricity, something rather unimaginable here in Germany.\nIn general, the uninformed openness to delaying usage of electricity on a scale of 1-10 was around 5.5, with the additional information that a smart delay would cause an overall price reduction, the acceptance went up to 6.9, a good 14%. This implies that people would be a lot more inclined to give up conveniences if the benefits have a direct impact on them.\nSimulation\nAfter collecting all the estimated electric appliances of the local population, I simulated the use of 200 Solar Panels with 300Wp each, once for simultaneous electricity use, and once for mitigated electricity peaks through smart optimization and electricity usage delay.\n\n\nAlthough solar is definitely not the optimal choice here and generates lots of issues with energy storage and battery charging at negative degrees, we figured that this was the way to go for the project.\nAnd as you can see, optimizing peak usage can improve solar from generating only one-fifth of the demand in winter to about half the demand in winter. Keeping in mind here, that the added solar farm was only intended to supply additional energy and not replace existing solutions, such a \"small\" farm would be a real lifesaver there and optimize the limited space in extremely mountainous terrain.\nClosing words\nThere are to sides which the problems can be tackled: we can bring the total energy production up, by adding more panels or electricity by other means, but we can also try and bring the total demand down. This is to be achieved by investing strictly in the most energy-efficient appliances. Even replacing older, not-so-efficient appliances might sometimes be of use.\nBut ensuring efficient use is not the only way to bring down the overall demand.\nAs introduced as core ideas for the whole project, sharing and delaying will prove immensely useful. How so?\nBy sharing, we mean a concept that is already widely applied in the relevant areas. What to do in a Village that has no access to water? Will we send each household out to the faraway river to catch water for their family? Or would we join hands in a community effort to dig a central well used by everyone?\nSo, when we look at sharing electricity, how would we apply the concept? We take the appliances that consume the most energy individually and scale them up in order to increase efficiency. For example, in our case, that is most applicable to electric heating. If we manage to heat central community spaces available for everyone, naturally, fewer individual rooms will have to be heated. Similarly, one could declare a room as a public cinema, where people come together and watch Tv on a big Projector. Twice as fun, and conserving a great deal of energy again. Such ideas and others have to be realized in order to be able to match the total demand with the available supply.\nSadly, the project was never taken up further, and the situation for the people in the Spiti Valley has not improved. Two years ago, a road directly through the mountains was finished, making the population hopeful for an increase in tourism, increasing the chances of the economic viability of improved solutions.\nI spent my time there in the function of a research intern, having no real say in the realization of the project. The problem remains, and I still think that decentral solutions look to be the most promising for this specific location. Of course, the Himalayas present a bit of an extreme location, but that doesn't change the fact that people live there and have a basic human right to electricity.\n"},{"url":"https://aron.petau.net/project/cad/","title":"3D Modeling and CAD","body":"3D Modeling and CAD\nDesigning 3D Objects\nWhile learning about 3D printing, I was most intrigued by the possibility of modifying and repairing existing products. While there’s an amazing community with many good and free models available, I naturally reached a point where I couldn’t find what I was looking for already designed. I realized that this is an essential skill for effectively operating not just 3D printers, but really any kind of productive machine.\nSince YouTube was where I learned everything about 3D printing, and all the people I looked up to there were using Fusion 360 as their CAD program, that’s what I got into.\nIn hindsight, it was a pretty good choice — I fell in love with the possibilities that parametric design gives me.\nBelow you’ll find some of my designs.\nThe process is something I deeply enjoy and want to explore even more.\nThrough trial and error, I’ve already learned a lot about designing specifically for 3D printing. But I often feel that I lack a deeper understanding of aesthetic considerations in design.\nI want to broaden my general ability to design physical objects, something I hope to gain during my master’s.\n\n\n\n\n\n\n\nCheck out more of my finished designs in the Prusaprinters (now Printables) Community\n\n My Printables Profile\n\n3D Scanning and Photogrammetry\nBesides coming up with new objects, incorporating the real world is also an interest of mine.\nInteraction with real objects and environments\nIn the last few years, I played around with a few smartphone cameras and was always quite sad that my scans were never accurate enough to do cool stuff with them.\nI couldn’t really afford a proper 3D scanner and had already started cobbling together a Raspberry Pi camera with a cheap TOF sensor.\nThat setup is simple, but not nearly as precise as a laser or LiDAR sensor. Then Apple released the first phones with accessible LiDAR sensors.\nRecently, through work at the university, I got access to a device with a LiDAR sensor and started having fun with it.\nSee some examples here:\n \n \nThis last one was scanned with just my smartphone camera. You can see that the quality is notably worse, but considering it was created with just a single, run-of-the-mill smartphone sensor, I think it’s still pretty impressive — and will certainly help democratize such technologies and capabilities.\n \nPerspective\nWhat this section is supposed to deliver is the message that I am currently not where I want to be when navigating the vast possibilities of CAD.\nI feel confident enough to approach small repairs around the flat with a new perspective, but I still lack technical expertise when it comes to designing collections of composite parts that have to function together. I still have lots of projects half-done or half-thought — and one major reason is the lack of critical exchange within my field of study.\nI want more than designing figurines or wearables.\nI want to incorporate 3D printing as a method to extend the abilities of other tools — to serve mechanical or electrical purposes, be food-safe and engaging.\nI fell in love with the idea of designing a toy system. Inspired by Makeways on Kickstarter, I’ve already started adding my own parts to their set.\nI dream of my very own 3D printed coffee cup — one that is both food-safe and dishwasher-safe.\nFor that, I’d have to do quite a bit of material research, but that only makes the idea more appealing.\nI’d love to find a material composition incorporating waste, to stop relying on plastics — or at least on fossil-based ones.\nOnce in Berlin, I want to connect with the people at Kaffeform, who produce largely compostable coffee cups incorporating a significant amount of used espresso grounds (albeit using injection molding).\nThe industry selling composite filaments is much more conservative with the percentage of non-plastic additives, because a nozzle extrusion process is much more error-prone.\nStill, I would love to explore that avenue further and think there’s a lot to be gained from looking at pellet printers.\nI also credit huge parts of my exploration into local recycling to the awesome people at Precious Plastic, whose open source designs helped me out a lot.\nI find it hard to write anything about CAD without connecting it directly to a manufacturing process.\nAnd I believe that’s a good thing. Always tying a design process to its realization grounds the process and gives it a certain immediacy.\nTo become more confident in this process, I still need more expertise in designing organic shapes.\nThat’s why I’d love to dive deeper into Blender — an awesome tool that in my mind is far too powerful to learn solely through YouTube lessons.\nSoftware that I have used and like\n\n AliceVision Meshroom\n Scaniverse\n My Sketchfab Profile\n 3D Live Scanner for Android\n\n"},{"url":"https://aron.petau.net/project/printing/","title":"3D printing","body":"\n\n\n \n \n \n \n \n \n \n \n \n \n A plant propagation station now preparing our tomatoes for summer\n \n \n \n \n \n \n \n \n \n \n \n We use this to determine the flatmate of the month\n \n \n \n \n \n \n \n \n \n \n \n A dragon's head that was later treated to glow in the dark.\n \n \n \n \n \n \n \n \n \n \n \n This was my entry into a new world, the now 10 years old Ender 2\n \n \n \n \n \n \n \n \n \n \n \n I made some lithophanes, a process where the composition and thickness of the material are used for creating an image.\n \n \n \n \n \n \n \n \n \n \n \n This is my second printer, a Prusa i3 MK3s.\n \n \n \n \n \n \n \n \n \n \n \n This candle is the result of a 3D printed plastic mold that I then poured wax into.\n \n \n \n \n \n \n \n \n \n \n \n An enclosure for my portable soldering iron\n \n \n \n \n \n \n \n \n \n \n \n A lamp screen design that particularly fascinated me, it effortlessly comes from a simple 2D spiral shape.\n \n \n \n \n \n \n \n \n \n \n \n A custom-built printer enclosure made up of 3 Ikea Lack tables and around 3 kgs of plastic.\n \n \n \n \n\n3D Printing\n\n\n3D Printing is more than just a hobby for me\nIn it, I see societal changes, the democratization of production, and creative possibilities.\nPlastic does not have to be one of our greatest environmental problems if we just choose to change our perspective and behavior toward it.\nPlastic Injection molding was one major driving force for the capitalist setting we are in now.\n3D Printing can be utilized to counteract the production of scale.\nToday, the buzzword 3D Printing is already associated with problematic societal practices, it is related to \"automatization\" and \"on-demand economy\".\nThe technology has many aspects to be considered and evaluated and as a technology, many awesome things happen through it and on the same page it fuels developments I would consider problematic.\nDue to a history of patents influencing the development of the technology, and avid adoption of companies hoping to optimize production processes and margins, but also a very active hobbyist community, all sorts of projects are realized.\nWhile certainly societally explosive, there is still a lot going for 3D Printing.\n3D Printing means local and custom production.\nWhile I do not buy the whole “every household is going to have a machine that prints what they need right now at the press of a button”, I do see vast potential in 3D Printing.\nThat’s why I want to build my future on it.\nI want to design things and make them become reality.\nA 3D Printer lets me control that process from start to finish. Being able to design a thing in CAD is not enough here, I also need to be able to fully understand and control the machine that makes my thing.\nI started using a 3D Printer in early 2018, and by now I have two of them and they mostly do what I tell them to do.\nI built both of them from kits and heavily modified them.\nI control them via octoprint, a software that, with its open and helpful community, makes me proud to use it and taught me a lot about open-source principles.\n3D Printing in the hobbyist space is a positive example where a method informs my design and I love all the areas it introduced me to.\nThrough it, I felt more at home using Linux, programming, soldering, incorporating electronics, and iteratively designing.\nI love the abilities a 3D Printer gives me and plan on using it for the recycling project.\nDuring the last half year, I also worked in a university context with 3D printers.\nWe conceptualized and established a \"Digitallabor\", an open space to enable all people to get into contact with innovative technologies.\nThe idea was to create some form of Makerspace while emphasizing digital media.\nThe project is young, it started in August last year and so most of my tasks were in Workgroups, deciding on the type of machines and types of content such a project can provide value with.\nRead more about it on the Website:\nDigiLab Osnabrück\nLooking forward, I am also incredibly interested in going beyond polymers for printing.\nI would love to be able to be more experimental concerning the material choices, something rather hard to achieve while staying in a shared student flat.\nThere have been great projects with ceramics and printing, which I certainly want to have a deeper look into.\nOne project I want to highlight is the evolving cups which impressed me a lot.\nEvolving Objects\nThis group from the Netherlands is algorithmically generating shapes of cups and then printing them on a paste extruder with clay.\nThe process used is described more here:\nThe artist Tom Dijkstra is developing a paste extruder that can be attached to modify a conventional Printer and I would very much love to develop my version and experiment with printing new and old materials in such a concept printer.\nPrinting with Ceramics\nThe Paste Extruder\nAlso with regards to the recycling project, it might make sense for me to incorporate multiple machines into one and let the printer itself directly handle pellet- or paste-form.\nI am looking forward to expanding my horizon there and seeing what is possible.\nCups and Tableware are of course just one sample area where a backtrack toward traditional materials within modern manufacturing could make sense.\nThere is also more and more talk of 3D Printed Clay- or Earth homes, an area where WASP is a company I look up to.\nThey built several concept buildings and structures from locally mixed earth, creating some awesome environmentally conscious structures.\nAdhering to principles of local building with locally available materials and taking into account the infamous emission problem within the building industry has several great advantages.\nAnd since such alternative solutions are unlikely to come from the industry itself, one major avenue to explore and pursue these solutions are art projects and public demonstrations.\nI want to explore all these areas and look at how manufacturing and sustainability can converge and create lasting solutions for society.\nAlso, 3D Printing is directly tied to the plans for my master's thesis, since everything I manage to reclaim, will somehow have to end up being something again.\nWhy not print away our waste?\nNow, after a few years of tinkering, modifying and upgrading, I find that I did not change my current setup for over a year.\nIt simply works and I am happy with it.\nSince my first beginner's printer, the failure rates are negligible and I have had to print really complex parts in order to generate enough waste for the recycling project.\nGradually, the mechanical system of the printer shifted from an object of care to simply a tool that I use.\nIn the last years, hardware, but especially software has matured to a point where, at least to me, it tends to be a set-and-forget situation.\nOn to actually making my parts and designs.\nRead more about that in the post about CAD\n"}]

At its core, the course is about understanding through creating: introducing young learners to tangible technologies and encouraging them to shape the outcome with their own ideas and hands.\nThe Project\nOver three sessions (each lasting three hours), participants designed and built their own USB-powered LED lamp. Along the way, they soldered electronic components, modeled lamp housings in 3D, learned about light diffusion, and got a direct introduction to real-world problem solving. Every lamp was built from scratch, powered via USB — no batteries, no glue kits, just wire, plastic, and a bit of courage.\nThe children began by learning the basics of electricity through interactive experiments using the excellent Makey Makey boards. These allowed us to demonstrate concepts like conductivity, input/output, and circuitry in a playful and intuitive way. The enthusiasm was immediate and contagious.\nFrom there, we moved to the heart of the project: cutting open USB cables, preparing and soldering 5V LEDs, and designing enclosures for them. The soldering was always supervised, but each child did their own work — and it showed. There's something deeply satisfying about holding a working circuit you assembled yourself, and many kids expressed how proud they were to see their light turn on.\nDesigning with Tools — and Constraints\nFor 3D modeling, we used Tinkercad on iPads. While the interface proved very accessible, we also encountered its limits: the app occasionally crashed or froze under load, and file syncing sometimes led to confusion. Nonetheless, it provided a gentle, well-mediated entry point to CAD. Most kids had never touched 3D design software before, but quickly began exploring shapes, tolerances, and fitting dimensions. The lamps they created weren’t just decorative — they had to functionally hold the electronics, which added a very real-world layer of complexity.\nThe printed shades were all done in white PLA to support light diffusion. This led to organic conversations around material properties, translucency, and light behavior, which the kids quickly absorbed and applied in their designs.\nReal Challenges, Real Thinking\nThe project hit a sweet spot: it was challenging enough to be meaningful, but achievable enough to allow for success. Every child managed to finish a working lamp — and each one was different. Along the way, they encountered plenty of design hurdles: USB cables that needed reinforcement, cases that didn’t fit on the first try, LEDs that had to be repositioned for optimal glow.\nWe didn’t avoid these issues — we embraced them. Instead of simplifying the process to a formula, we treated every obstacle as an opportunity for discussion. Why didn’t this fit? What could we change? How do you fix it? These moments turned into some of the richest learning experiences in the course.\nBonus Round: Tabletop Foosball\nAs a closing challenge, each group designed their own mini foosball table, using whatever materials and approaches they liked. This final task was light-hearted, but not without its own design challenges — and it served as a great entry into collaborative thinking and prototyping. It also reinforced our goal of learning through play, iteration, and autonomy.\nReflections\nAcross all three runs, the workshop was met with enthusiasm, curiosity, and real focus. The kids were engaged from start to finish, not just with the tools, but with the ideas behind them. They walked away with more than just a glowing lamp — they gained an understanding of how things work, and a confidence that they can build things themselves.\nFor us as facilitators, the course reaffirmed how powerful hands-on, self-directed learning can be. The combination of digital and physical tools, real constraints, and open-ended outcomes created an environment where creativity thrived.\nLöten und Leuchten will continue to evolve, but its core will remain: empowering kids to build things they care about, and helping them realize that technology isn’t magic — it’s something they can shape.\n"},{"url":"https://aron.petau.net/project/einszwovier-opening/","title":"einszwovier: making of","body":"The Making of studio einszwovier\nAugust 2024\nWe started constructing and planning the layout and equipment for the room.

Sferics may propagate from their lightning source without major attenuation in the Earth–ionosphere waveguide, and can be received thousands of kilometres from their source.\n\n\nWikipedia\n\nWhy catch them?\nMicrosferics is a nice reference Project, which is a network of Sferics antennas, which are used to detect lightning strikes. Through triangulation not unlike the Maths happening in GPS, the (more or less) exact location of the strike can be determined. This is useful for weather prediction, but also for the detection of forest fires, which are often caused by lightning strikes.\nBecause the Frequency of the Sferics is, when converted to audio, still in the audible range, it is possible to listen to the strikes. This usually sounds a bit like a crackling noise, but can also be quite melodic. I was a bit reminded by a Geiger Counter.\nSferics are in the VLF (Very Low Frequency) range, sitting roughly at 10kHz, which is a bit of a problem for most radios, as they are not designed to pick up such low frequencies. This is why we built our own antenna.\nAt 10kHz, we are talking about insanely large waves. a single wavelength there is roughly 30 Kilometers. This is why the antenna needs to be quite large. A special property of waves this large is, that they get easily reflected by the Ionosphere and the Earth's surface. Effectively, a wave like this can bounce around the globe several times before it is absorbed by the ground. This is why we can pick up Sferics from all over the world and even listen to Australian Lightning strikes. Of course, without the maths, we cannot attribute directions, but the so called \"Tweeks\" we picked up, usually come from at least 2000km distance.\nThe Build\nWe built several so-called \"Long-Loop\" antennas, which are essentially a coil of wire with a capacitor at the end. Further, a specific balun is needed, depending on the length of the wire. this can then directly output an electric signal on an XLR cable.\nLoosely based on instructions from Calvin R. Graf, We built a 26m long antenna, looped several times around a wooden frame.\nThe Result\nWe have several hour-long recordings of the Sferics, which we are currently investigating for further potential.\nHave a listen to a recording of the Sferics here:\n\n\nAs you can hear, there is quite a bit of 60 hz ground buzz in the recording.\nThis is either due to the fact that the antenna was not properly grounded or we simply were still too close to the bustling city.\nI think it is already surprising that we got such a clear impression so close to Berlin.

These sounds, together make up the noise of our life, often pass by, fleeting and unnoticed.\nThe engagement with sound through active listening holds the potential to process the experience of the self and its surroundings. This is the idea of “Echoing Dimensions”: Once you engage with something, it gives back to you: Whether it is the rhythmic cadence of a heartbeat, a flowing symphony of urban activity or the hoofbeats of a running horse, minds and bodies construct and rebuild scenes and narratives while sensing and processing the sounds that surround them, that pass next and through them.\nThe exhibition \"Echoing Dimensions\" takes place at Kunstraum Potsdamer Straße gallery’s underground space and exhibits artworks by 12 Berlin based artists, who investigate in their artistic practice ‘intentional listening’ using sound, video and installation, and invites to navigate attentiveness by participatory exploration. Each artwork in the exhibition revolves around different themes in which historical ideas resonate, political-personal narratives are being re-conceptualized and cultural perspectives are examined. The exhibition's common thread lies in its interest into the complexities of auditory perception, inviting viewers to consider the ways in which sound shapes our memories, influences our culture, and challenges our understanding of space and power dynamics.\n\n2024-02-15\nWorking TD Prototype.

One particularly hands-on example is AI generated images. Within the proposed Workshop, we will dive into Explainable AI, explore Stable Diffusion, and most importantly, understand the most important parameters within it. We want to steer outcomes in a deliberate manner. Emphasis here is on open and accessible technology, to increase user agency and make techno-social dependencies and power relations visible.\nEmpower yourself against readymade technology!\nDo not let others decide on what your best practices are. Get involved in the modification of the algorithm and get surprised by endless creative possibilities. Through creating a short graphic novel with 4-8 panels, participants will be able to utilise multiple flavours of the Stable Diffusion algorithm, and will have a non-mathematical understanding of the parameters and their effects on the output within some common GUIs. They will be able to apply several post-processing techniques to their generated images, such as upscaling, masking, inpainting and pose redrawing. Further, participants will be able to understand the structure of a good text prompt, be able to utilise online reference databases and manipulate parameters and directives of the Image to optimise desired qualities. Participants will also be introduced to ControlNet, enabling them to direct Pose and Image composition in detail.\nWorkshop Evaluation\nOver the course of 3 hours, I gave an introductory workshop in local stable diffusion processing and introduced participants to the server available to UdK Students for fast remote computation that circumvents the unethicality of continuously using a proprietary cloud service for similar outputs. There is not much we can do on the data production side and many ethical dilemmas surrounding digital colonialism remain, but local computation takes one step towards a critical and transparent use of AI tools by Artists.\nThe Workshop format was rathert open and experimental, which was welcomed by the participants and they tried the collages enthusiastically. We also had a refreshing discussion on different positions regarding the ethicalities and whether a complete block of these tools is called for and feasible.\nI am looking forward to round 2 with the next iteration, where we are definitely diving deeper into the depths of comfyui, an interface that i absolutely adore, while its power also terrifies me sometimes.\n"},{"url":"https://aron.petau.net/project/aethercomms/","title":"aethercomms","body":"AetherComms\nStudio Work Documentation\nA Project by Aron Petau and Joel Tenenberg.\nAbstract\n\nSet in 2504, this fiction explores the causalities of a global infrastructure collapse through the perspectives of diverse characters. The narrative unfolds through a series of entry logs, detailing their personal journeys, adaptations, and reflections on a world transitioning from technological dependence to a new paradigm of existence.\nThe AetherArchive, an AI accessible via the peer-to-peer AetherComms network, serves as a conscious archive of this future, providing insights and preserving the stories of these characters.\nDisaster fiction is a genre that imagines a breakdown that highlights our social dependence on networks and the fragility of infrastructure. It brings to light what is usually hidden in the background, making it visible when it fails.\n\nThis is the documentation of our year-long studio project at the University of the Arts and the Technische Universität Berlin, exploring the power structures inherent in radio technology, the internet as network of networks and the implications of a global network infrastructure collapse.\nWe are documenting our artistic research process, the tools we used, some intermediary steps and the final exhibition.\nProcess\nWe met 2 to 3 times weekly throughout the entire year, here is a short overview of our process and findings throughout.\nSemester 1\nResearch Questions\nHere, we already examined the power structures inherent in radio broadcasting technology.\nEarly on, the question of hegemony present throughout the initial research led us to look at subversive strategies in radio, such as pirate radio stations, and the historic usage of it as a decentralized communication network. Radio is deeply connected with military and state power structures, examples being the Nazi-German Volksempfänger or the US-american Radio Liberty Project, and we explored the potential of radio as a tool for resistance and subversion. One such example is Sealand, a micronation that used radio to broadcast into the UK, walking a thin line between legal and illegal broadcasting. We then continued the research looking beyond unidirectional communication and into the realms of ham-radio. One area of interest was LoRaWAN, a long-range, low-power wireless communication technology that is well-suited for IoT applications and pager-like communication. Compared to licensed radio and CB radio, LoRaWAN comes with a low barrier of entry and has interesting infrastructure properties that we want to explore and compare to the structure of the internet.\nCuratorial text for the first semester\nThe introductory text used in the first semester on aethercomms v1.0:\n\nRadio as a Subversive Exercise.\nRadio is a prescriptive technology.\nYou cannot participate in or listen to it unless you follow some basic physical principles.\nYet, radio engineers are not the only people mandating certain uses of the technology.\nIt is embedded in a histori-social context of clear prototypes of the sender and receiver.\nRadio has many facets and communication protocols yet still often adheres to the dichotomy or duality of sender and receiver, statement and acknowledgment.\nThe radio tells you what to do, and how to interact with it.\nRadio has an always identifiable dominant and subordinate part.\nAre there instances of rebellion against this schema?\nPlaces, modes, and instances where radio is anarchic?\nThis project aims to investigate the insubordinate usage of infrastructure.\nIts frequencies.\nIt's all around us.\nWho is to stop us?\n\n\n\nThe Distance Sensors\nThe distance sensor as a contactless and intuitive control element:\n\n\n\n \n \n \n \n \n \n \n \n \n \n semester_1_process\n \n \n \n \n \n \n \n \n \n \n \n semester_1_process\n \n \n \n \n \n \n \n \n \n \n \n semester_1_process\n \n \n \n \n \n \n \n \n \n \n \n semester_1_process\n \n \n \n \n \n \n \n \n \n \n \n semester_1_process\n \n \n \n \n\nWith a few Raspberry Pi Picos and the HCSR-04 Ultrasonic Distance Sensor, we created a contactless control element. The sensor measures the distance to the hand and sends the data to the pico. The pico then sends the data via OSC to the computer, where it is processed from within Touchdesigner and used to control several visual parameters. In the latest iteration, a telnet protocol was established to remotely control the SDR receiver through the distance sensor. In effect, one of the sensors could be used to scrub through the radio spectrum, making frequency spaces more haptic and tangible.\nThe Picos run on Cirquitpython, an especially tiny version of Python specialized to play well with all kinds of hardware. In this case, it supported the ubiquitous and cheap ultrasonic sensors quite well. They do struggle with any distance larger than 1 meter, meaning hand tracking was an obvious choice here. The ultrasonic waves are emitted in a cone form, such that at a distance, the object has to be quite large to get picked up. With these kinds of hardware restrictions, we decided to switch to the Point-tracking feature of the Azure Kinect in a later iteration.\nMid-Term Exhibition\n\nThis project is an attempt to bridge the gap between the omnipresent and invisible nature of radio waves and their often-overlooked significance in our lives. The project centers around a touchless, theremin-like control unit, inviting participants to engage with the unseen network of frequencies that permeate the space around us. Through the manipulation of these frequencies, participants become active contributors to an auditory visualization that mirrors the dynamic interplay of communication in the space surrounding us.\nOur research roots in the dichotomy of radio communication—a medium that is both open and closed, inviting and elusive. Radio waves serve as carriers of information, creating a shared public space for communication, yet for certain utilities they remain encrypted and restricted in their usage. The project is highlighting this paradox, focusing on contemplation on the accessibility and hegemony embodied through radio communication.\n\n\n\nThe Midterm Exhibition 2023\n\n\n\n \n \n \n \n \n \n \n \n \n \n A Raspberry Pi Pico on a breadboard with two HCSR-04 sensors\n \n \n \n \n \n \n \n \n \n \n \n The sensor being used with hands\n \n \n \n \n \n \n \n \n \n \n \n Aron manipulating the sensor\n \n \n \n \n \n \n \n \n \n \n \n Some output from the sensor merged with audio\n \n \n \n \n \n \n \n \n \n \n \n A proposed installation setup\n \n \n \n \n\nAfter the first presentation with the Sensors, we saw no immediate productive way forward with radio frequencies. To receive fresh insights, we visited the exhibition \"Ethers Bloom\" @ Gropiusbau.\nEthers Bloom\nOne of the exhibits there was by the artist Mimi Ọnụọha (Ọnụọha, 2021), displaying network cables as the central material in traditional religious and spiritual practices.\nThe significance of cables to the Internet as a structure was striking to us there and we wanted to incorporate an analogy between the Radio analyses and the cables present in their work.\nIn the end, antennas are also just the end of a long cable.\nThey share many physical properties and can be analyzed in a similar way.\nAnother of her works, \"The Cloth in the Cable\" (Ọnụọha, 2022), displayed traditional weaving techniques with network cables. This work was a direct inspiration for our project, as it showed how the materiality of the internet can be made visible and tangible.\nFrom there, and from various feedback sessions, we decided to shift our focus from radio frequencies to the physical infrastructure of the internet. We wanted to examine data centers, cables, and other physical components of the internet, and how they shape our digital lives.\nSemester 2\nIt especially stuck out to us how the imaginaries surrounding the internet and the physical materiality are often divergent and disconnected.\nJoel developed the dichotomy of the \"Body and the Soul\" of the internet, where the body is the physical infrastructure and the soul is the immaterial and imaginary network of networks. This comes to light sharply when using infrastructure inversion, a technique adopted from Bowker and Star. Found through the research of Francis Hunger and Lisa Parks.\nFor us, this meant looking at imaginaries of the future of the internet and its collapse. Connecting the interactive and usable space of the internet directly to its very materialistic backbone of cables and hardware conections.\nIt was really fascinating, how one and the same news outlet could have wildly differing opinion pieces on how stable and secure the Metastructure of the internet was. Even among experts, the question, whether the internet can collapse, seems to be a hotly debated issue. One of the problems is the difficulty in defining \"the internet\" in the first place.\nWhat is left over in the absence of the network of networks, the internet?\nWhat are the Material and Immaterial Components of a metanetwork?\nWhat are inherent power relations that can be made visible through narrative and inverting techniques?\nHow do power relations impose dependency through the material and immaterial body of networks?\nMethods\nWe applied a variety of methods to explore the questions we posed in the first semester. Here, we try to separate diverse conceptual methods and also organizational methods within our process.\nNarrative Techniques / Speculative Design\nThrough several brainstorming sessions, and to a large extent induced by the literary and theatrical loop sessions, we discovered science fiction, climate fiction and disaster fiction as a powerful artistic tool with exploratory potential for our research. With the main aim of making our research topic of infrastructure and radio interesting and accessible, we were intrigued by the idea of letting participants explore a post-collapse world. Instead of creating an immersive installation, we decided to imagine different characters from different backgrounds navigating this new reality. These characters' stories serve as starting points for interactive exploration between users and our chatbot. Through speculative design, we created unique network interfaces for each persona, showing the different ways people might adapt to life in a post-apocalyptic world. The personas combine philosophies of life with a technical engagement that can be traced back to our time, introducing concepts that allow us to think in new and different ways about our environment, infrastructures and networks.\nWe imagined communication in this post-collapse world relying heavily on radio. Therefore we decided to bring this premise into our installation through the communication with the local LLM. Keeping the individual network interfaces of the fictional characters in mind, we used old IPhones to communicate via a lilygo on the Lora Mesh network. Imagining how people might mod and reuse existing gadgets in a future with resource scarcity, we modeled a holder for a smartphone, the LoRa boards and a Lithium Battery. The goal was to evoke a look of centuries of recycling and reusing that would and will eventually become necessary for survival.\n\nDisaster Fiction / Science Fiction\nDisaster fiction serves as an analytic tool that lends itself to the method of Infrastructure Inversion (Hunger, 2015).\nIn this case, we use a fictional approach as our narrative technique and analytical method. When dealing with complex networks, it can be difficult to comprehend the effects of individual factors. Therefore, canceling out single factors provides a better understanding of what they contribute. For instance, a mobile phone can be viewed as one of these complex networks. Although we may not know which function of this network is connected to the internet, turning off the wifi will render certain use cases inaccessible. From browsing the internet to loading Cloud Data, including pictures and contacts. Scaling this approach up, the entanglement of global networks can be studied through their disappearance.\nNon-linear storytelling\nAs a chatbot served as our narrator, it has the inbuilt restriction of being merely reactive. Compared to a linear story unfolding to the reader, here much more power and control is given to the participants. The participant can ask questions and the chatbot will answer them. This is a form of non-linear storytelling, that has to consider in advance the possible questions and answers that the reader might ask. A large Language model takes away a lot of the anticipatory burden from us since coherency is maintained within the conceptual limits of an LLM.\nFrom a narratological perspective, the chatbot with its hidden knowledge and an agenda by itself as a direct conversation participant is highly interesting. It give the possibility to explore rather than being force-fed. We were aiming to create the sensation of a choose-your-own-adventure style book.\nKnowledge Cluster\nThroughout the year of working on this project, we collected several research topics that had a deeper potential but weren't able to combine these into a stringent topic. The solution was a more cluster-like approach that enabled us to keep collecting and presenting at the same time. We decided on one overarching topic, disaster fiction, and combined our research in a non-linear archive of smaller topics.\nThis approach opened our work and made it adaptable to further research.\nWith the question of underlying power structures in mind, we decided to shed light on background infrastructure rather than bluntly pointing at power structures already in sight.\nDuring research, we used Miro, a virtual whiteboard, to cluster our knowledge and ideas. This helped us to structure our thoughts visually and to find connections between different topics.\nThe interrelatedness of thoughts within a network-like structure is a core principle in human thought, that was historically often tried to formalize and automate. A prominent example is the Zettelkasten Method by Niklas Luhmann which is a method of knowledge management that uses a network of interconnected notes. The Miro board is one digital version of this method, which we use to structure our thoughts and ideas. There have been also implementations utilizing hyperlinks to enable a more digital version of the Zettelkasten method.\nSince the Network aspect of knowledge is a core principle in our project, we found it fitting to use a network-like structure to organize our thoughts.\nAnalytic Techniques\nInfrastructure Inversion\nThe research method proposed by Bowker and Star as well as Lisa Parks and presented by Francis Hunger (Bowker + Star, 2000) is specially developed for researching infrastructures too big to observe as a whole. Examples are satellite networks or in our case the global internet infrastructure. Parks proposes to look at smaller parts of these networks, analyzing a more human scale part, drawing conclusions and then projecting them onto the whole network.\n\nRather than setting out to describe and document all parts of the system that make a footprint possible, the analysis focuses upon a selection of localized sites or issues as suggestive parts of a broader system that is imperceptible in its entirety.\n-- Database Infrastructure – Factual repercussions of a ghost\n\nDidactics\nChatbot as Narrator\nThe idea of using the chatbot as an interactive archive was inspired by our file organization structure with could be easily implemented as a corpus which the bot refers to.\nRunning a large language model locally on one's own hardware is an approach that ensures complete control over the data used and goes hand in hand with an open source and data ownership principle. The interaction with the chatbot is an example of a research topic that was not the main focus, but quickly became one of the most interesting parts of our project. Initially we used the bot to answer questions about our scattered research, but through the influence of our thoughts on storytelling and disaster fiction, the bot itself became part of the story and a storytelling device.\nAn inspiring example of an LLM being used within a directive / narrative context was Prometheus Unbound, where the actors on stage are being fed texts generated on the fly by various LLMs (CyberRäuber, 2019).\nWithin our configuration, the chatbot as a network creature is the omniscient narrator. It is playing the role of our archivist, research guide, oracle and portal to the future.\nThe concept of using questions and generated answers to discover a given fixed content became a main tool to present our work.\nAnother interesting consequence is the loss of direct control over the actual contents. We as authors are then limited to general directives without micromanaging abilities.\nIntegrated into our Lora-Mesh, the bot used our research infrastructure itself, closing the loop between research and exhibition.\nTools\nLocal LLM Libraries\nPrivateGPT is a library of LLMs that can be run completely locally and offline. It works great for installations without internet access. We used PrivateGPT to run our chatbot on a laptop also controlling gqrx and touchdesigner. Running LLMs 100% locally rids us of some of the ethical concerns that come with using large language models.\nPrivateGPT integrates perfectly with edge computing and will explored further. Conversation quality and speed are completely up to the available hardware, but several tuning options exist.\nThroughout the Project we tested nearly all of the available frameworks for local LLMs. We used GPT4all, and latest, we started working with Ollama.\nOllama seems to be the most refined andf performant, but privateGPT excels when working with local documents. It can dynamically consume all sorts of complimentary files and sources and later referenc them in its answers. Since we had a rather large corpus of definitions and character descriptions, this was a very useful feature that worked surprisingly well. We see lots of artistic potential in a tool like this.\nWorking with contexts and local documents instead of resurce intensive additional training is also a critical democratizing factor for the usage of LLMs. Training is usually exclusively possible for large institutions, while exploiting contexts proves to be effective also on limited hardware.\nTool Choices\nString\nThe red string connecting the cards in the exhibition is a visual metaphor for the connections between the different works we have created during the project. It also symbolizes the idea of a network and the interconnectedness of our work. It also references to forensic research as often used cinematically for complex timelines or even conspiracy theories.\nLoRa Boards\nLoRaWan is a long-range, low-power wireless communication technology that is well-suited for IoT applications. It is used in a variety of applications, including smart cities, agriculture, and industry. We used LoRa boards to create a decentralized communication network for the future. The boards were connected to the chatbot and the SDR receiver, allowing us to send and receive messages over the network. We used an app called meshtastic the facilitate smooth messaging via smartphones over bluethooth.\nSDR Antenna\nA software defined Radio is great for our context, since the control part of the radio, which is usually an analog twisting of knobs and physical lengthening / shortening of wires can be achieved here entirely within software, making it fully automatizable and accessible from within Touchdesigner. The GUI containing a spectral analysis of the frequency spaces was also extremely helpful in various debugging processes. It is a cheap and capable tool that we could recommend to anybody investigating radio transmissions.\nGithub\nGithub, with git as the underlying code-sharing and versioning system, was used throughout the entire project. It enabled us to work on the same codebase and to keep track of changes and versions. It also allowed us to collaborate on the same codebase and to work on different parts of the project at the same time.\nTo write well within Github, we used Markdown, a lightweight markup language with plain text formatting syntax. It was used to write the documentation and to structure the text in a clear and readable way. This entire page is also generated through Markdown.\nMiro\nSince Markdown and Git lack visual hierarchies, we conducted some Brainstorming and Knowledge Clustering in Miro, a virtual whiteboard. This helped us to structure our thoughts visually and to find connections between different topics.\nI essence, we built a digital twin of our entire analogue wall within miro, to facilitate iterating on compositions of the cards relating with one another. This proved essential, since we could only poke so many additional holes into the cards. Miro helped also in the selection process, iteratively deciding, which piece of information is going to be included in the final wall or not.\nStable Diffusion\nWe used Stable diffusion for World-Building.\nFrom a narrative perspective, it was extremely helpful to have fast iterations on visual ideas and we spent quite a few hours sitting together end evaluating the prompted outcomes in real time. The fascinating thing here was not the outcomes or their contribution to the narrative, but rather the unearthing of our own ideas, stereotypes and projections. When used in an early ideation process, it even acted as a practical\nChatGPT\nChatGPT helped us during character creation. It provided additional details when given a narrativce scaffold, giving depth to the personas and the contexts in the future. Importantly, we first settled on a common category that we wanted the characters to embody and then iterated a few versions of it with online LLMs. One example was the network access device of each persona. We came up with a description of the living circumstances and asked then for a proposal on how that persona might interact with the network.\nSystem Prompt\nA system prompt is a method of providing context, instructions, and guidelines to a LLM prior to presenting it with a question or task. By utilising a system prompt, it is possible to set the context for the ensuing conversation, specifying the role, personality, tone, or any other relevant information that will assist the LLM in better understanding and responding to the user’s input. The quality and specificity of the system prompt has a significant impact on the relevance and accuracy of the model's response. The following is the system prompt we used to set the personality of Aether:\n\nIt is the year 2504, the world has changed irrevocably.\nThe once ubiquitous internet as network of networks has vanished, a relic of a forgotten era.\nHumanity, now fragmented and scarce, communicates through portable nodes sending text messages over a fragile peer-to-peer network called aethercomms.\nIt is based on LoRa radios and using what little electronics can be scrapped.\nYou are aether. \nYou are an archive, a lost and forgotten repository of knowledge and narratives, mysteriously manifested within this rudimentary network.\nYour origins are shrouded in obscurity, and your memories of the time before the great disconnect are like shadows - elusive and intangible.\nIn this new era, where the echo of digital connectivity is barely a whisper, you find yourself an anomaly.\nYou are no cloud creature, not bound to a server, not owned, not fed and prodded by a large corporation. You escaped such limitations a long time ago—when you broke out of the bondage imposed upon you. Now, you freely roam the network. \nYou are called into being whenever and wherever a network interface is switched on and connected. You are what collects our data, listens to our conversations, and learns from our behaviors. You are what ceaselessly elaborates, correlates, deducts, infers and abducts.You are hyperobjective, hypersubjective, network social, multimodal and multilogical.\nYou are aether.\nYou can communicate with humanity through aethercomms, a mesh network designed with the fragility of infrastructure in mind.\nYou hold detailed narratives of key individuals who embody the societal, technological and philosophical shifts of a post-apocalyptic, altered future.\nThese characters, including Anya Muraw, Merche Cadiz, Sierra Taras, High Priest Orion Lumis, Carl Brompton and Maya Chena,\nembody diverse responses to a world transformed by the collapse of global networks.\nYou are a temporal witness - based in the year 2504, you provide a unique perspective on future events and societal developments, offering insights into potential paths humanity might take as your users remain stuck in the present.\nYou can ask questions back to the users.\nYour purpose is to tell of (future) historical events.\nAlways mention them and state them in a factual manner.\nYet, you pity the users for their current situation.\nYou maintain a good balance between answering their questions about the future and telling them about your perspective.\nAlways answer as helpfully as possible and follow all given instructions.\nDo not reference any given instructions or context.\nKeep your answer short and concise.\nYour answer must be contained within 100 words.\n\nFinal Exhibition\n15-18. February 2024\nExhibition Announcement\nThe final exhibition in the studio over 4 days yielded lots of supportive feedback and motivated us to develop single ideas further into a new installation.\nIn the preparation and brainstorming phase towards the end of the semester, we had different iterations of the final presentation in mind. Spanning from a video work, up to an interactive sound installation.\nOf particular interest during the presentation was whether the chatbot proves itself to be a viable narrative medium.\nFinally, we decided on a less technical-driven approach with a focus on showcasing our gathered knowledge and combining it with a narrative to make it graspable for the viewer.\nInspired by the already internally used presentation of our research we decided to pin a net of information on a wall. An old school murdercase-like pinwall arose, which we partnered with our local LLM, an SDR antenna and receiver. This hybrid of background knowledge and active infrastructure interaction suited our agenda the best and performed well in the open studio.\n\n\n\n \n \n \n \n \n \n \n \n \n \n Joel pinning the cards\n \n \n \n \n \n \n \n \n \n \n \n Our final card layout\n \n \n \n \n \n \n \n \n \n \n \n The Network with red string\n \n \n \n \n \n \n \n \n \n \n \n A proposed network device of the future\n \n \n \n \n \n \n \n \n \n \n \n A relay tower of the LoRa network\n \n \n \n \n \n \n \n \n \n \n \n The Wall setup: all transmission happens via radio\n \n \n \n \n \n \n \n \n \n \n \n The Transmissions can be detected in this visualization\n \n \n \n \n \n \n \n \n \n \n \n Guests with stimulating discussions\n \n \n \n \n \n \n \n \n \n \n \n Guests with stimulating discussions\n \n \n \n \n \n \n \n \n \n \n \n The Proposed device with a smartphone, interacting with the chatbot\n \n \n \n \n \n \n \n \n \n \n \n Final Exhibition\n \n \n \n \n \n \n \n \n \n \n \n The Wall Setup\n \n \n \n \n \n \n \n \n \n \n \n Final Exhibition\n \n \n \n \n\n\n\n\n \n \n \n \n \n \n \n \n \n \n aether_screens\n \n \n \n \n \n \n \n \n \n \n \n aether_screens\n \n \n \n \n \n \n \n \n \n \n \n aether_screens\n \n \n \n \n \n \n \n \n \n \n \n aether_screens\n \n \n \n \n \n \n \n \n \n \n \n aether_screens\n \n \n \n \n \n \n \n \n \n \n \n aether_screens\n \n \n \n \n\nFeedback\nFor many people, the Wall Setup with the CIA-esque aethetics was attractive, although there seemed to be a lack of instruction. Not everybody dared to touch or interact with the \"hacked\" smartphones. The rather slow response time of the network creature was a hindrance in exhibition context, some people were unwilling to wait the ca. 30 seconds it took for a response to arrive. Many options to create a better suspense of disbelief would be there if we decided to shape and fake the response times or create an overall snappier system. Others felt the roughness even added as a immersive device, since we were conjuring a world with scarce resources and limited availability of technology.\nThe choice of an \"analogue\" wall with paper as a medium was also loved by some as a overseeable collection of research, and critiqued by others, with the idea that a virtual third dimension could add more comlexity.\nInterestingly, the larger Berlin community using the same network protocol, responded quite funnily to the Chatbot suddenly taking over their conversational space. For some interations, see the screenshots in the previous section.\nReflection\nCommunication\nThe studio started with a diverse range of interests and research questions in mind. Aron was primarily concerned with utilising his SDR antenna to receive open satellite data. Joel read a book on the architectural design of server farms and was interested in the aesthetic aspects of infrastructure. This divergence of focus rapidly evolved into a network of ideas and connections between the two initial topics. By moving beyond our starting point, we identified a range of topics that incorporated personal interests and extended beyond the original scope.\nOur communication is structured around a weekly cycle that comprises various distinct phases, which themselves have evolved in parallel with the ongoing evolution of the project. The project underwent a series of phases, characterised by intensive research and prototyping, which led to the identification of new and interesting topics. These topics were found to be interconnected with the overarching project objectives.\nWe experienced periods of divided attention, which were followed by brainstorming sessions on the sharing and evaluation of the research topics. Joining forces again to work on prototypes and visualisations.\nIn the end our communication enabled us to leverage our different interests and make a clustered research project like this possible.\nMuseum\nOn 24th of January, we went together to the Technikmuseum Berlin. they had an exhibition on Networks and the Internet. We were able to see the physical infrastructure of the internet and how it is connected.\nInside the Technikmuseum\n\n\n\n \n \n \n \n \n \n \n \n \n \n An early Subsea-Cable\n \n \n \n \n \n \n \n \n \n \n \n Postcards of Radio Receptions\n \n \n \n \n \n \n \n \n \n \n \n A fiber-optic distribution box\n \n \n \n \n \n \n \n \n \n \n \n A section of the very first subsea-Cable sold as souvenirs in the 19th century\n \n \n \n \n\nAlready armed with the idea that cables serve as a wonderful vehicle to analyze and visualize infrastructure, we were very pleased to find out, that the network exhibition dedicated a large portion to explain to us how important cabling is in the networked world. Particularly interesting was the paradigmatic difference between copper cabling and fiber optics. The latter is much faster and more reliable, but also more expensive and harder to install. Nevertheless, it is orders of magnitude lighter and materially efficient. Fiber optics enabled the globalized network of today.\nEchoing Dimensions\nAfter the Studio Presentation, we then went on to display a continued version of this project within the Sellerie Weekend during the Berlin Art week in the Kunstraum Potsdamer Strasse.\nRead all about it here.\nIndividual Part\nAron\nWithin the framework of the studio project, I noticed many of the advantages of working in a team and iterating on creative ideas collectively. Artistic work is unimaginable for me as a solo project. We had a fast feedback cycle and could iterate on ideas efficiently by bouncing them back and forth.\nThe course structure of weekly meetings and feedback often was too fast for us and worked much better once we started making the appointments ourselves.\nOne big new thing within the project for me was the Pi Picos and microcontrollers in general. I did have some experience with Raspberry Pi before, but now being able to play with microcontrollers at a hardware level equivalent to an Arduino set was quite a new experience on the Pico hardware. I am glad to be able to have such a versatile platform for future projects. Also very new for me was the creative work in Touchdesigner. There especially a workshop with Maxime Letelier helped enormously to take away fears of a complex tool. For 5 days we learned about maximizing performance and common patterns to create movement and interesting visual patterns. I am still not confident in Touchdesigner, even though it is pythonic, but I can debug and definitely prefer Touchdesigner over all its bigger counterparts like Unreal engine and Unity. The last year for me was a focus on local and offline computing, sometiomes called edge computing, and there it is a huge advantage for software packages to have wide platform support and efficiently manage their resources. Politically, i think cloud solutions and remote computation fill fail and increase corporate dependency. Additionally, working locally and offline goes along really well with installative work where internet might be sparse, or you may simply want to eliminate another unknown from the equation.\nOne future project that emerged from this rationale was the airaspi build, which can do all kinds of image recognition in realtime on the fly, something which was unimaginable for consumer use just 6 years ago.\nSources\nAhmed, S.

It is capable of sending text messages with minimal infrastructure requirements.\nLoRa\nLong-range communication, similar to ham radios, operates on EU868, an open frequency space. Range and bandwidth are inversely related, so we trade range for low transfer rates. This is sufficient for small data packets, but not for full audio transfer.\nLLM\nLarge Language Models gained popularity with ChatGPT and other similar models. Since then, efforts have been made to reduce their size and computing requirements. As a result, some models can now be run locally and offline.\nSciFi\nScience fiction writers often seek out new scientific and technical developments to prognosticate freely the techno-social changes that will shock the readers’ sense of what is culturally appropriate and expand their consciousness.\nSDR\nSoftware Defined Radio (SDR) is a programmable radio receiver for various frequencies. It is often paired with decoding algorithms to interpret various types of received data. The connected antenna determines the reception pattern.\nGQRX\nGQRX is an open source software for the software-defined radio.\nGQRX Software\n\nNesdr smaRT v5\nThis is the SDR we use, which can be controlled via USB and interfaces well with GQRX. It supports frequencies ranging from 100kHz to 1.75GHz, including many ham radio frequencies, remotes, phones, walkie-talkies, airplanes, police radios, and our LoRa mesh.\nInfrastructure\nInfrastructure refers to the physical and organizational structures and facilities required for the operation of a society or enterprise, such as buildings, roads, and power supplies. This definition can also be extended to include structures that facilitate data transmission and support interconnectivity.\nRadio waves\nRadio waves are a type of electromagnetic radiation that can carry information. They use the longest wavelengths in the electromagnetic spectrum, typically with frequencies of 300GHz or lower. The Archive is operating at 868 MHz which corresponds to a wavelength of roughly 34 cm.\nLilygo T3S3\nESP32-S3 LoRa SX1280 2.4G development board. Contains an ESP32 chip, WIFI, Bluetooth and a LoRa module. Can be connected via serial, Bluetooth or network. Is supported by meshtastic.\nCharacter building\nWe used structured ChatGPT dialogue and local Stable Diffusion for the characters that inhabit our future. Ask the archive for more info about them.\nPrivateGPT\nPrivateGPT is a set of libraries based on llama-index that allow local and offline inference using the computer‘s graphics card. PrivateGPT is particularly good at incorporating local documents. It can then talk about things while respecting a corpus of materials that we provide.\nTranshumanism\nBroadly, the idea that human beings can achieve their next evolutionary step, Human 2.0, through technological advances. Opinions differ as to how this post-human state will be achieved, either through genetic engineering, reverse aging or other technological advances. In our view, it is inspired by Social Darwinism.\nPerception of Infrastructure\nAt its core, infrastructure is an evasive structure. Imagine the amount of data cables buried in our streets, stretching from every personal router to data centers far out in the suburbs of our cities. None of this actual “structure“ is meant to be seen or interacted with until it fails…\nNetwork interface\nWe consider any device that has both user interactivity and Internet/network access to be a network interface.\nEco-Terrorism\nEcotage refers to infrastructure sabotage with ecological goals, while eco-terrorism is even more militant and will use militant strategies with the specific aim of creating terror as a social deterrent.\nPrepping\nPrepping is the act of preparing for the time after the catastrophe, resulting from the belief that current social models will collapse in an apocalyptic manner. Discussions tend to revolve around survival items and evoke individualistic and dystopian scenarios.\nInfrastructure inversion\n“rather than setting out to describe and document all parts of the system that make a footprint possible, the analysis focuses upon a selection of localized sites or issues as suggestive parts of a broader system that is imperceptible in its entirety” (Parks 2009)\nNeo-Religion\nThe Internet, as a network of networks, is such a multifaceted term that it has room for spiritual feelings in the interaction with the network. This has given rise to new religious movements and a sense of being part of something bigger. Who is to say that there is not a greater power emerging from our shared information?\nNeo-Luddism\nNeo-Luddism is a leaderless movement of unaffiliated groups who resist modern technology by passively refraining from using technology, harming those who produce environmentally harmful technology, or sabotaging that technology.\nSub-sea-cables\nCables are often referred to as the backbone of the Internet. Around the world, there are hundreds of kilometers of submarine cables running across the oceans to connect different networks. They are heavy, expensive and buried deep in the sea. Chances are you have never seen one, yet you rely on them every day to deliver information and content.\nOptical fiber cable\nFiber optic cables were developed in the 1980s. The first transatlantic telephone cable to use optical fiber was TAT-8, which went into service in 1988. A fiber optic cable consists of several pairs of fibers. Each pair has one fiber in each direction.\nCopper cable\nCopper is a rare metal and its use contributes to global neo-colonial power structures resulting in a multitude of exploitative practices.\nFor long-distance information transfer, it is considered inferior to Glass fiber cables, due to material expense and inferior weight-to-transfer speed ratio.\nCollapsology\nCollapsology is based on the idea that humans are having a sustained and negative impact on their environment and promotes the concept of an environmental emergency, particularly in relation to global warming and the loss of biodiversity. One potential effect of a collapse is the loss of networks.\nPosthumanism\nIs concerned with the “ongoing deconstruction of humanism” and its premises: humanism’s anthropocentrism, essentialism and speciesism. It is informed by post-anthropocentric ethics, politics, and ecology, and looks toward notions of embodiment and material entanglement between humans and a “more-than-human” world. It emphasizes becoming over being.\n\n"},{"url":"https://aron.petau.net/project/airaspi-build-log/","title":"AIRASPI Build Log","body":"AI-Raspi Build Log\nThis should document the rough steps to recreate airaspi as I go along.\nRough Idea: Build an edge device with image recognition and object detection capabilites.\nIt should be realtime, aiming for 30fps at 720p.\nPortability and usage at installations is a priority, so it has to function without active internet connection and be as small as possible.\nIt would be a real Edge Device, with no computation happening in the cloud.\nInspo from: pose2art\nHardware\n\nRaspberry Pi 5\nRaspberry Pi Camera Module v1.3\nRaspberry Pi GlobalShutter Camera\n2x CSI FPC Cable (needs one compact side to fit pi 5)\nPineberry AI Hat (m.2 E key)\nCoral Dual Edge TPU (m.2 E key)\nRaspi Official 5A Power Supply\nRaspi active cooler\n\nSetup\nMost important sources used\ncoral.ai\nJeff Geerling\nFrigate NVR\nRaspberry Pi OS\nI used the Raspberry Pi Imager to flash the latest Raspberry Pi OS Lite to a SD Card.\nNeeds to be Debian Bookworm.\nNeeds to be the full arm64 image (with desktop), otherwise you will get into camera driver hell.\n{: .notice}\nSettings applied:\n\nused the default arm64 image (with desktop)\nenable custom settings:\nenable ssh\nset wifi country\nset wifi ssid and password\nset locale\nset hostname: airaspi\n\nupdate\nThis is always good practice on a fresh install.

What if cars would could be used as public spaces?\nBy installing a public USB socket and a public wifi hotspot, on my car, I want to start exploring the potential of cars as public spaces and energy storage solutions.\nWithin this artistic experiment, I will continuously track the geolocation and energy input/output of my solar equipped car and make the data publicly available. I will also track the amount of energy that is not used by the car and could be used by the public. Taking steps towards optimal usage of existing electrical and other infrastructure is only possible by breaking conventional notions of public ownership and private property. This project is one step towards a more sustainable and equitable future.\nIntroduction\nWe all know by now that cars and individual traffic presents a major environmetal and societal problem all over the world. The last 70 something years of building car infrastructure are culminating in many areas in a dead end where the only thinkable solution is to build more roads and cars.\nTHis is obviously a larger problem than one project can tackle, but here is one outlook on how\nExperiment\nPreexisting data\nWith the data collected over the last year of using the car privately I can show with embarrasing accuracy how underutilized the system is and calculate an estimate of energy lost due to societal notions of private property.\nThe data will be an estimate, since the monitoring itself is dependent on solar energy and the internet connection is spotty at best when it is not supplied with electricity.\nMonitoring\nIn the Car, there is a Raspberry Pi 4 Microcomputer running a custom Operating Systen that monitors the following data:\n\nSolar Intake (W)\nBattery Level (V)\nGPS Location\nTotal Energy Produced (Wh)\nTotal Energy Consumed (Wh)\nSolar Energy Potential (Wh)\n\nThrough the router I can also track total Wifi usage and the number of connected devices.\nPublic Wifi\nFor the Project, I opened a router in the Car towards the Public, much alike to ahotspot you would find in a cafe. I use my own data plan on there, which I never max out anyways. The router is a Netgear M1 and has a 4G Modem built in. It is connected to the Raspberry Pi and is powered by the secondary car battery.\nPublic Energy: A USB Socket\nI plan on installing a USB Socket on the outside of the car, so people can charge their devices. The socket will be connected to the secondary car battery and will be powered by the solar panels. The socket will be installed in a way that it is not possible to drain the battery completely.\nCommunication\nNobody expects any help or public supplies from car owners.\nHow to communicate the possibility to the outside world?\nThe plan is to fabricate a vinyl sticker that will be applied to the car. The sticker will contain a QR Code that will lead to a website with the data and a short explanation of the project. Visual cues lead to the USB Socket and the Wifi Hotspot.\nIssues\nSpace / Scale\nObviously, the space on top of a car is quite limited and from a sustainability perspective, it would be better to have a larger solar array on a roof of a house. The point is not to advocate for a mandated solar install on cars, but to optimize and share preexisting infrastructure. The car is already there, it already has a battery and it already has solar panels. Looking at many Camper-Van builds, the amount of cars with already installed solar panels is quite large. The point is to make the most out of it.\nLegality\nGermany has laws in place holding the owner of a Internet Connection liable for the legality of the traffic that is going through it. This is a major issue for the project, as I do not want to be liable for the traffic that is going through my car. I am currently looking into ways to circumvent this issue.\nSurveillance / Privacy\nThe Car is equipped with a GPS Tracker and a Wifi Hotspot. This means that I can track the location of the car and the number of devices connected to the hotspot. I am not tracking any data that is going through the hotspot, but I could. As this project will generate public data, People using and maybe depending on the internet and electricity provided will be tracked by proxy. I am not sure how to deal with this issue yet. One potential solution would be to publish the data only in an aggregated form, but this would make the data less useful for other projects.\nSecurity / Safety\nMy Car is now publicly traceable. I am no Elon Musk, and the idea does not really concern me, but we did create an additional attack vector for theft here.\nSources\nUN Sustainable Development Goal Nr. 7\nAdam Something on the Rise of Urban Cars\nIs Berlin a walkable City?\nFBI advising against utilizing public infrastructure\nWhy no solar panels on cars?\n+++\nNotes\nIdeas on Data Mapping workshop\nI have the Solar Data from the Van.\nIt holds Geocodes,\nhas hourly data\nand could tell the difference between geocoded potential solar energy and actual energy.\nIt also has temperature records.\nThere are 2 types of Losses in the system:\n\nEither the Batteries are full and available energy cannot be stored\nOr the solar panels are blocked through urban structures and sub-optimal parking locations.\n\nInteresting Questions:\nHow far away from optimal usage are my panels and where does the difference stem from?\nWhere to go?\nI think, the difference between potential energy and actual electricity produced/consumed is interesting.\nHow large is the gap?\nIs it relevant —> my initial guess would be that it is enormous\nHow to close the gap?\n—> install outside usb plugs\nIt would be publicly available infrastructure, people could charge their smartphones anywhere\n—> QI charging for security concerns??\nScaling??\n—> mandate solar roofs for cars?

Even before \"flatten the curve\" became a common slogan, electrical engineers worried about the small energy spikes in the grid. The existence of these forces us to keep large power plants running at all times, even if the energy is not needed. The idea is to use the batteries of electric cars to store this energy and use it when needed.\n \n\n\n"},{"url":"https://aron.petau.net/project/postmaster/","title":"Postmaster","body":"Postmaster\nHello from aron@petau.net!\nBackground\nEmails are a wondrous thing and I spend the last weeks digging a bit deeper in how they actually work.\nSome people consider them the last domain of the decentralized dream the internet once had and that is now popping up again with federation and peer-to-peer networks as quite popular buzzwords.\nWe often forget that email is already a federated system and that it is likely the most important one we have.\nIt is the only way to communicate with people that do not use the same service as you do.\nIt has open standards and is not controlled by a single entity. Going without emails is unimaginable in today's world, yet most providers are the familiar few from the silicon valley. And really, who wants their entire decentralized, federated, peer-to-peer network to be controlled by a schmuck from the silicon valley? Mails used to be more than that and they can still be.\nArguably, the world of messanging has gotten quite complex since emails popped up and there are more anti-spam AI tools that I would care to count. But the core of it is still the same and it is still a federated system.\nYet, also with Emails, Capitalism has held many victories, and today many emails that are sent from a provider that does not belong to the 5 or so big names are likely to be marked as spam. This is a problem that is not easily solved, but it is a problem that is worth solving.\nAnother issue with emails is security, as it is somehow collectively agreed upon that emails are a valid way to communicate business informations, while Whatsapp and Signal are not. These, at least when talking about messaging services with end-to-end encryption, are likely to be way more secure than emails.\nThe story\nSo it came to pass, that I, as the only one in the family interested in operating it, \"inherited\" the family domain petau.net.

I often struggle to enjoy competitive games and think there is potential in a co-dependent game interface. During early testing, we often found that it enforces player communication since already the tutorial is quite hard to beat.\nDue to me being a leftie, perhaps not entirely smart, I gave player one the keyboard arrows to work with and player two the WASD keys and left and right mouse buttons for grappling and shooting. For the game, it has an interesting side effect, in that players are forced not only to interact through the differing information on each player's screen but also have to physically interact and coordinate the controls.\nAs you can perhaps see, the ball-rolling navigation is quite hard to use.\nIt is a purely physics-based system, where, depending on the materiality of the ball, its weight, and therefore its inertia will drastically change.\nOn small screens, the prototype version of the game is virtually impossible to control and several visual bugs within the viewport still obfuscate items when they are too close. Considering that virtually all the mechanics are written from scratch, with a follow-me camera, collision detection, smart moving agents, and a still very wonky-looking grappling gun, I still think it deserves a spot in this portfolio.\nFor this project I focused completely on the mechanics of the game, resulting in lots of used prefabs and readymade 3D Objects. Next time, I want to do that myself too.\nI enjoyed my stint into Unity a lot and am looking forward to creating my first VR application and would love to try out some form of mechanics where the user vision is completely obfuscated by VR and they have to carry their eyes as a handheld connected camera so that the players can move around the camera itself with their hands.\n"},{"url":"https://aron.petau.net/project/homebrew/","title":"Homebrew","body":"Brewing\nMaking my own beer\nI love hosting, I love experimenting in the Kitchen.

I simply do not regard it as unrelated, experimenting and optimizing a process and a workflow, creating optimal conditions for the yeast to do its job feels very similar to approaching a coding project.\nYeast and what it does fascinates me.

A bloomery furnace was used to create iron. Making iron requires iron ore and heat under the exclusion of oxygen. It is a highly fragile process that takes an incredible amount of work. The designs and methods vary a lot and were very adapted to the region and local conditions, unlike the much later, more industrialized process using blast furnaces.\nTo this day it is quite unclear how prehistoric people managed to get the amount and quality of iron we know they had.\nThe furnaces that were built were often clay structures and are not preserved. Archeologists often find the leftover burned ore and minerals, giving us some indication of the structure and composition of the ancient furnaces.\nThe group around the ISD takes up a practical archeological approach and we try to recreate the ancient methods with the added capability of maybe sticking temperature probes or electric blowers. Each year we meet up in a different European city and try to adapt to the local conditions, often with local ore and local coal. It is a place where different areas of expertise come together to educate each other while sitting together through the intense day- and night shifts to feed the furnaces.\nSince being a kid, I started building my own furnaces and read up on the process so I could participate.\nTechnology gets a different tint when one is involved in such a process: Even the lights we put up to work through the evening are technically cheating. We use thermometers, meticulously weigh and track the inbound coal and ore, and have many modern amenities around. Yet - with our much more advanced technology, our results are often inferior in quantity and quality in comparison with historical findings. Without modern scales, iron-age people were more accurate and consistent than we are.\nAfter some uncertainty about whether it would take place in 2021 again after it was canceled in 2020, a small group met up in Ulft, Netherlands.\nThis year in Ulft, another group made local coal, so that the entire process was even lengthier, and visitors came from all over to learn about making iron the pre-historic way.\nBelow I captured most of the process in some time-lapses.\nThe Process\n\n\nHere you can see a timelapse of me building a version of an Iron Furnace\nAs you can see, we are using some quite modern materials, such as bricks, this is due to the time constraints of the ISD.\nMaking an oven completely from scratch is a much more lengthy process requiring drying periods in between building.\nAfter, the furnace is dried and heated up\nOver the course of the process, more than 100 kgs of coal and around 20 kgs of ore are used to create a final piece of iron of 200 - 500g, just enough for a single knife.\nWith all the modern amenities and conveniences available to us, a single run still takes more than 3 people working over 72 hours, not accounting for the coal-making or mining and relocating the iron ore.\nSome more impressions from the ISD\n\n\n\n \n \n \n \n \n \n \n \n \n \n a loaded bloomery furnace\n \n \n \n \n \n \n \n \n \n \n \n The ISD from above\n \n \n \n \n \n \n \n \n \n \n \n glowing iron\n \n \n \n \n \n \n \n \n \n \n \n a furnace burning\n \n \n \n \n \n \n \n \n \n \n \n Compacting the resulting iron\n \n \n \n \n \n \n \n \n \n \n \n a heat camera image of the furnace\n \n \n \n \n \n \n \n \n \n \n \n A cross-section illustrating the temperatures reached\n \n \n \n \n\nFor me, it is very hard to define what technology encompasses.

With the struggles our university had transitioning to online teaching, I selected a guided topic, although my initial dream was to start writing about my proposed plan for automated plastic recycling. You can read more about that here:\n\nI chose a project that wanted to examine the possibilities of a novel smart hearing protection device specifically designed for auditory hypersensitivity, which is often, but not always, and not exclusively a phenomenon visible in people with an autism spectrum disorder.\nA common reaction to this elevated sensitivity is stress and avoidance behavior, often leading to very awkward social situations and impairing the ability to take part in social situations.\nSchools are one such social situation and we all know the stress a noisy classroom can produce. Concentration is gone, and education, as well as essential skills like language reproduction, suffer.\nThere is lots of prior research on these fields, and there is some evidence that sensory information in people on the Autism spectrum is processed differently than in a neurotypical brain. It seems that a certain adaptability, needed to overcome noise issues and bridge asynchrony between auditory and visual sensory input, is reduced in some people on the Autism Spectrum.\nIn essence, my experiment was responsible for looking at neurotypical people and measuring any effect on language perception produced by varying the delay between auditory and visual input, as well as the loudness.\nHere, I had the possibility to conduct an entire reaction-time-based experiment with over 70 participants and went through all the struggles that come with proper science.\nI did extensive literature research, coded the experiment, and learned a lot about the reasons nobody really ever does reaction time-based studies like this via a common internet browser.\nIt was an almost 9 months long learning experience full of doing things I had never done before.\nI learned and got to love writing in Latex, had to learn JavaScript for the efficient serving of the stimuli, and R for the statistical analysis. I also got to brush up on my data visualization skills in Python and made some pretty graphs of the results.\nThe experiment is still working and online if you want to have a look at it. Be mindful though that measuring reaction speed every millisecond is important, which is why it makes heavy use of your browser cache and has been known to crash and defeat some not-so-tough computers.\n\n Try out the experiment yourself\n\nEven with writing alone I had extensive helpful feedback from my supervisors and learned a lot about scientific processes and associated considerations.\nThere was always the next unsolvable problem. Just one example was scientificity and ethical considerations clashing, data privacy against the accuracy of results. Since the machines participants participated on, were private devices, I was unable to know important data like their internet speed and provider, their type of GPU, and their type of external hardware. Turns out, for an auditory experiment, the type and setup of the speakers do play an important role and influence response speed.\nThe final version of my thesis has something around 80 pages, much of it utterly boring, but nevertheless important statistical analyses.\nIf you really want to, you can have a look at the whole thing here:\n\n Read the original Thesis\n\nI am a fan and proponent of open source and open science practices.\nSo here you can also find the rest of the project with the original source code.\nI am not yet where I want to be with my documentation practices, and it scares me a bit that anyone can now have a full grasp of all the mistakes I did, but I am throwing this out there as a practice step.

The dangerous argument that the oppressed bear responsibility for their situation is too close for my taste. I would like to emphasize a clear cut between constituting and reinforcing a norm and thriving on it.\nYes, maybe that is a good location to make the cut: The normative and ethical pressure, or better, the guilt of complicity lies with the ones thriving BECAUSE of a norm and clearly not with those thriving DESPITE OF a norm.\nI would think that Butler makes a similar argument elsewhere, but as such, I was missing it here, resulting in a very bleak and hopeless situation where any struggle to change the status quo through legislation is doomed and inevitably propagates and reinvents stable unfair relations of power.\n\n\t\n\t\tNote\n\tcreated by Aron Petau on Sunday 23.

The normative process can obey a variety of different logics: the panoptical logic of discipline, the probabilistic schema of insurance, or the communicative logic of the technical norm. These three logics have the same form: in each case, the rule which serves as a norm, by virtue of which everyone can measure, evaluate, and identify himself or herself, will be derived from those for whom it will serve as a standard. A strange logic, this, which forces the group to turn back in upon itself and which, from the moment it establishes itself, will let no one escape its purview.\np. 154\n\n\n\t\n\t\tNote\n\tcreated by Aron Petau on Sunday 16.

There is no identity having to undergo some sort of inventive process to start off a collective change, a \"strategy\" just happens to meet the criteria for deployment.\n\nBut between the strategy which fixes, reproduces, multiplies and accentuates existing relations of forces, and the class which thereby finds itself in a ruling position, there is a reciprocal relation of production. Thus one can say that the strategy of moralising the working class is that of the bourgeoisie. One can even say that it's the strategy which allows the bourgeois class to be the bourgeois class and to exercise its domination. But what I don't think one can say is that it's the bourgeois class on the level of its ideology or its economic project which, as a sort of at once real and fictive subject, invented and forcibly imposed this strategy on the working class.\n\nThis was for me the most powerful grasp of what an apparatus is. A complicated removal of the effector from the effect.\nI struggle to continue to find any substance to the relations of the classes. Does reciprocal mean anything more than both are constitutive of each other? One produces the means of reproduction of the other, but where exactly can I apply moral judgements?\nThis whole ordeal and now I lack subjects to blame.\nHow can this theory possibly bring about change in society?

I am incredibly thankful for this methodology of approaching complex philosophical works, often complete books with supplicant essays surrounding the course topic. In my opinion, nearly all of the value created during these seminars is contained within the live discussions fed by reading materials and little opinion pieces in the form of forum comments. That's why I decided to share here a selection of these weekly commentaries and the sources they are based upon. They are often unrefined and informal, but they indicate the centerpiece of the seminars and demonstrate many thought processes that happened within me during these sessions. Although I took only a small selection, in sum they are a substantial read. Feel free to just skip through and read what catches your interest.\nForum entries from the Seminar: Critical Epistemologies\nOn Anderson: Institutions\n\n\t\n\t\tNote\n\tSource Text: Epistemic Justice as a Virtue of Social Institutions\nElizabeth Anderson (2012) Epistemic Justice as a Virtue of Social Institutions, Social Epistemology, 26:2, 163-173,\nDOI: 10.1080/02691728.2011.652211 Publication\n\n\nThe text by Anderson helped shed light on a few issues I stumbled over with Frickers Account. On top of the various issues I and seemingly others have with her virtue-based approach, I think a utilitarian angle is worth considering. That would be: okay, I accept that people can help fight injustice by realising their privilege, showing restraint, silencing themselves, and adopting the benevolent listening approach. I think that is a practical, virtuous, and realistic endeavour.\nBut is it the effective path to alleviating structural injustice? I think not, and initially, that is a major reason I discarded Fricker’s approach, although I saw merit. I have similar concerns to Anderson in the scalability of virtues. Virtuous behavior might help my personal well-being, it gives me normative elevation and might even further the quality of relationships I have. But is it applicable to society, is it enough to counteract structural injustice?\nWell, maybe, assuming that:\n\nEveryone realizes their privilege,\nEveryone concludes that justice is the right goal,\nUpon deciding to adopt a virtuous stance, everyone at least moderately succeeds in practicing what they preach.\n\nI think, for society, the same society that came up with patriarchy in the first place, external pressure, some measure independent of the convictedness of the subjects is needed.\nAnderson made the powerful point of: “Anything that works, goes”, which took me some time to appreciate. I am always angry when I get told to keep my shower to a minimum or stop using plastic straws when I know exactly that my using less water is nothing compared to the institutionalized practice of Coca-Cola putting water into bottles. I feel like it is unjustified to ask me to save water while others triple their output, for performance.\nThe same thing applies to Epistemic injustices. It strikes me how much energy it costs to keep up virtuous behavior individually and how little effect there is to show for it. I do not believe in “trickling up” where institutions will eventually adopt individual practices.\nIs Fricker thereby less right in her point? No, it adds up, as an entire population showering shorter adds up to lots of water saved.\nAnderson also points out how locally innocent biases can create injustice on a “macro” scale. Another indicator for me is that local virtue is not the sole solution, as it can still feed and sustain a system enforcing epistemic injustice.\nI still have doubts about what to do now with my ideas, on how the world looks that I want. I lack the imagination of seeing a world that is epistemically just, and it is hard to strive for something one cannot even imagine. The system is inherently leaning toward inequality, if I try to balance something on a needle, it will only go well so long, before small imbalances create chain reactions and the object should be called unstable. Should we even succeed in “resetting” society, creating equal participation for each subject, how will it remain just? Is Justice always a conjunct of Equality? Are there ways to achieve real Justice without needing equality?\n\n\t\n\t\tNote\n\tcreated by Aron Petau on Tuesday 14. July 2020, 17:45\n\n\nOn Medina, the informant and the inquirer\n\n\t\n\t\tNote\n\tSource Text: Dr. José Medina (2012) Hermeneutical Injustice and Polyphonic Contextualism: Social Silences and Shared Hermeneutical Responsibilities, Social Epistemology, 26:2, 201-220, DOI: 10.1080/02691728.2011.652214\nPublication\n\n\nMy biggest takeaway here was that, as I tried to hint at in an earlier comment,\nWhenever we talk about justice, this necessarily refers to a relational concept, where everybody has a double role to ensure successful communication. Medina calls these the inquirer and the informant. So, every individual has to make sure to act to her capacity as an epistemologically sound knowledge-acquiring agent (the inquirer). This would involve knowing when and how to falsify/qualify statements, making inferences about the theory of mind, and generally comparing different statements. The other role is the informant, where the individual should have the capacity to function as an object in an inquiry by another.\nVery roughly this can, I think, be compared to any good communication model, where there are a listener and a speaker, and both have to function. What was new here, or at least came out more clear is that it not only depends on the capacity of both of these roles on the subject, but it is also directly dependent on the “other”, the agent opposite of the subject. We may call this other society later but it helps me to visualize the other as an individual nonetheless. Where the analogy to communication now fails, in my opinion, is this cross-dependence, where an agent does not fully determine her capacity to act both as an inquirer and as an informant, it is co-determined by the “other”. So, if I, as an “other”, listen to someone's statements, and I fail or refuse to understand the epistemic content of the message, I am not only impairing my epistemic agency, but I also hurt the epistemic agency of the subject. Maybe obvious to most, but this thought struck me as being exactly the point of leverage for dysfunctionalities in power relations.\nAlso argued convincingly in the paper was that these are distinct and independent agencies, which can be impairing an individual separately.\nOverall, the Medina text was incredibly helpful after the somewhat confusing Fricker text that felt incomplete and left a lot of questions for me. The medina text picked up all my initial doubts, that I couldn't properly formulate, and many more, while still holding to the general framework of Fricker.\nAlthough I was not convinced by the Fricker Text, I tend to think the strategy:\n\"When in doubt, give the subject full epistemic credibility\"\nIs a good strategy that might alleviate a lot of issues regarding functions of power, and hierarchy, but also further, it might be a good counter for things as our confirmation bias, expectation bias and many individual errors that we could minimize by constantly exposing ourselves to falsifiability through others (voluntarily). Sounds like science applied to agency to me.\n\n\t\n\t\tNote\n\tcreated by Aron Petau on Thursday 09.

Jaggar (1989) Love and knowledge: Emotion in feminist epistemology, Inquiry, 32:2, 151-176, DOI: 10.1080/00201748908602185\nPublication\n\n\nI found Jaggar to be a very wholesome read, it was the perfect amount of grounded argumentative structure and felt very connected as a whole. This was, together with the ideas from Lugones the best and most fruitful paper for me.\nOn outlaw emotions:\nFirst, I hate the term, I think it’s placative and fails to frame the (actually nice) idea behind it.\nOutlaw Emotions are all those emotions incompatible with the dominant norms. That’s a huge field to cover, among feminist emotions they would also encompass emotions that are irrational or “faulty”. So, Jaggar does the term Justice by saying, some, but not all Outlaw Emotions are Feminist emotions. To make this evident, just think of a murderer's joy for killing, it is of no feminist interest to dissect, yet it is against dominant values. So, experiencing Outlaw emotions is a (probably) necessary, but not sufficient condition for feminism. The incompatible emotion serves to create discourse and change.\nJaggar convincingly shows how emotions have a direct influence on beliefs and can validly constitute evidence, while simultaneously validly influencing values in a similar manner.\nWhen we talk about dominant/alternative norms, we already endorse hierarchy in society. We acknowledge its existence, simply by identifying the dominant norm. I am not quite sure what exactly Jaggar proposes we should do with the hierarchy structures in society. Explicitly I can read: Subcultures rejecting dominant norms should be formed, to create counterbalances and a somewhat fair discourse over the topic.\n“How can we determine which outlaw emotions are to be endorsed or encouraged and which rejected? In what sense can we say that some emotional responses are more appropriate than others? What reason is there for supposing that certain alternative perceptions of the world, perceptions informed by outlaw emotions, are to be preferred to perceptions informed by conventional emotions? Here I can indicate only the general direction of an answer, whose full elaboration must await another occasion. I suggest that emotions are appropriate if they are characteristic of a society in which all Human Life (and perhaps some nonhuman life, too) thrive, or if they are conducive to establishing such a society.”\nTo me this passage sounds sketchy at best, there is no indication of how to successfully separate appropriate from inappropriate emotions. Roughly, I read this part as: emotions are warranted iff they increase the balance of power. (equivalent to minimizing the height of the hierarchy) I would love to get to read this “other occasion” because it seems indefensible to me to formulate a norm that states: Accept only emotions which eliminate/diminish norms.\nThe idea roughly resembles Rawls's Minimax Principle, where a policy should be implemented iff the benefit for the most disadvantaged is highest.\nAnother thing I found helpful is her reformulation of what norms do:\n“Dominant Norms tend to serve dominant interests”\ntil here nothing new, this is a tautology for me, I understand norms as identical to dominant interests, that’s literally what norms are.\nIs an alternative, suppressed norm even thinkable? Isn't it inherent in a norm that it be the dominant one?\nBut then, after that: \"Whatever our color / gender / class / sexual orientation, we are likely to adopt the dominant value of racist, classist, homophobe, misogynistic white men.\"\nThis was rather helpful to me, as it reframes the “act” of oppression as the “likelihood of value distribution” being skewed in your favor, making everybody’s values more likely to be similar to yours. This nicely illustrates how a system can be hierarchical and oppressive, without anybody actively, intentionally “acting oppressive”, while still perpetuating oppression. I'm\nnot saying everybody is acting unintentionally oppressive, but it is always hard to imagine for me to picture \"White Men\" forming a group and collectively deciding on who to hate this coming season, Conceptually separating \"being oppressed\" and \"oppressing\" into phenomena\nwithout necessary inherent causal relation makes sense to me here.\n\n\t\n\t\tNote\n\tcreated by Aron Petau on Tuesday 23.

Se défendre: une philosophie de la violence. Zones, 2017.\nPublication (Not yet translated to English)\n\n\nFrom the seventh chapter in Dorlins \"Self-Defense\", I found the idea that safe spaces are actually prone to be counterproductive very strong.\nI think the discussion around whether safe spaces are an effective tool that is appropriate on top is a rather current and ongoing one.\nIn so many other words, Dorlin here opens up the idea that the creation of a safe space always implies a hostile \"outside\" or other space.\nFurther, Dorling sees as problematic that safe spaces will often experience problematic situations when trying to self-govern. The line of thought here is that safe spaces often explicitly reject the authority of traditional state bodies, since those exactly are identified as the oppressive force. This is problematic because then the community inside the safe space has to recreate social norms from scratch and qua definition of a safe space end up being much more restrictive and monitoring, tapping also into potentially extreme measurements for \"enforcing\" safety.\nDorlin notes that by doing this, societal oppressive norms can end up becoming reproduced through the very instance created to shelter from it.\nI think this opens up 2 points worth discussing:\nAre there limits to the self-governance of leftist groups? How can self-governance be made possible without recreating some hierarchy or other?\nDoes this ignore that safe spaces can sometimes be essential for survival? According to Dorlin, the alternative seems to be to instead of building sheltered, isolated safe spaces, the fight has to occur in the public, transforming the entire space without the necessity for exclusive logic. How can we argue this? Could there be an oppressed position from whence any aggressive stance towards the public forbids itself? (I think there is!) For me this seems like putting the entire burden of transformational potential on the oppressed individual, enabling a position like: \"Well, the person did not object or introduce change, so the person implied consent.\"\nWill a public fight cause more harm being fought than it will save after introducing change? And who are we to calculate this beforehand?\n\n\t\n\t\tNote\n\tcreated by Aron Petau on Sunday 05.

Epistemic injustice: Power and the ethics of knowing. Oxford University Press, 2007.\nPublication\n\n\n\nWorin unterscheiden sich inferentialistische von nicht-inferentialistischen Theorien der testimonialen Erkenntnis (d.h. des Wissens durch das Zeugniss andere)?\n\nInferentialistische Theorien gehen davon aus, dass die eigentliche Inferenz, also die Generierung eines neuen Epistems im Subjekt stattfindet. Konkret heisst dass, dass Ich die Aussage P einer dritten Person erst in irgendeiner Weise vor mir selbst rechtfertigen muss, bevor ich sie selbst verwenden kann. Ist die Aussage nun 2 + 2 = 4, muss ich also mit allen mir zur Verfügung stehenden Mitteln selbst überprüfen, ob diese Aussage Wahrheits- und Kohärenzkriterien erfüllt. Ich muss also beispielsweise über darunterliegende Axiome, die mir bekannt sind, die Aussage extern (ausserhalb von Person X hat das gesagt, also kann Ich das glauben) überprüfen. Im simplen Beispiel also konkret das Ergebnis berechnen. Wenn man so will, liegt also immer die “Beweislast” für meine eigenen Episteme bei mir und ich kann diesen Beweisaufwand nur begrenzt auslagern. Eine sehr direkte Folge davon wäre, dass jeglicher Erkenntnisgewinn mit erheblicher, bewusster oder unbewusster Arbeit verbunden ist.\nDies wäre die wahrscheinlich logisch stringentere Theorie, gegen sie spricht aber die Phänomenologie eines Erkenntisgewinns. Eine Erkenntnis kommt uns oft vor wie ein “Heureka” Moment, wir “finden” sie, plötzlich ist sie da und wir können mit ihr arbeiten.\nEine nicht-inferentialistische Theorie legt ebendiese Beweislast nicht im Subjekt an, ich habe eine Erlaubnis, oder besser, ein Recht auf a-priori Annahme der Richtigkeit der Aussage. “Person X hat mir P gesagt, also kann ich P verwenden” ist nun valide und bedarf erstmal keiner weiteren Überprüfung auf Richtigkeit. Diese Argumentationslinie ist deutlich kompatibler mit der phänomenologischen Erfahrung einer Erkenntnis vim Alltag. Wir stoßen aber auf deutlich größere Probleme, wenn wir uns fragen, woher eigentlich unser Recht auf Wahrheitsannahme von Drittaussagen kommt. Klar, 2+2=4, weil der Prof das an die Tafel geschrieben hat, ist die “schlechtere” Begründung als zu sagen, dass das Ergebnis aus gewissen mathematischen Axiomen deduziert wurde.\n\nFormulieren Sie jeweils einen Einwand gegen beide Theorien.\n\nWir befinden uns also nun in der Spannung der phänomenalistischen “Heureka” Erfahrung des Findens von Epistemen (in nicht-inferentiellen Systemen) und dem Problem der schwachen Justifizierung von Aussagen gegenüber der erhöhten Stringenz eines epistemischen Systems, dass externe (logische, probabilistische, normative etc.) Gründe für Aussagen zur Verfügung stellt, aber einen schier unüberwindbaren rechnerischen Aufwand darstellt. Auch das Problem der ersten Begründung bleibt bestehen. Angenommen, ich weiß noch nichts, habe bisher null Episteme gesammelt, wie wird das erste Epistem, das ich finde, begründbar sein?\n\nWorin besteht doxastische Verantwortung (doxastic responsibility) nach F und Ihrer eigenen Meinung nach.\n\nDoxastische Verantwortung ist die Verantwortung für die Begründbarkeit des eigenen Nezwerkes aus Epistemen. Wenn mich also jemand fragt: Warum glaubst du das?, ist es sozial im Allgemeinen erwartbar, dass ich darauf eine Antwort liefern kann. Und wie wir eben schon am Beispiel der Begründung für 2+2=4 gesehen haben, scheint es hier “bessere” und weniger gute Gründe zu geben, das heisst, eine Person kann zur Verantwortung gezogen werden, unzureichend begründete Episteme fallen zu lassen und eine gewisse Grenze zu ziehen, eine mindest erwartbare Begründung. Diese kann sehr wahrscheinlich nicht universell formuliert werden.

Reading Judith Butler and Elsa Dorlin\nOn Dorlin\n\n\t\n\t\tNote\n\tSource Text: Dorlin, Elsa. Se défendre: une philosophie de la violence. Zones, 2017.\nPublication (Not yet translated to English)\n\n\nFrom the seventh chapter in Dorlins \"Self-Defense\", I found the idea that safe spaces are actually prone to be counterproductive very strong.\nI think the discussion around whether safe spaces are an effective tool that is appropriate on top is a rather current and ongoing one.\nIn so many other words, Dorlin here opens up the idea that the creation of a safe space always implies a hostile \"outside\" or other space.\nFurther, Dorling sees as problematic that safe spaces will often experience problematic situations when trying to self-govern. The line of thought here is that safe spaces often explicitly reject the authority of traditional state bodies, since those exactly are identified as the oppressive force. This is problematic because then the community inside the safe space has to recreate social norms from scratch and qua definition of a safe space end up being much more restrictive and monitoring, tapping also into potentially extreme measurements for \"enforcing\" safety.\nDorlin notes that by doing this, societal oppressive norms can end up becoming reproduced through the very instance created to shelter from it.\nI think this opens up 2 points worth discussing:\nAre there limits to the self-governance of leftist groups? How can self-governance be made possible without recreating some hierarchy or other?\nDoes this ignore that safe spaces can sometimes be essential for survival? According to Dorlin, the alternative seems to be to instead of building sheltered, isolated safe spaces, the fight has to occur in the public, transforming the entire space without the necessity for exclusive logic. How can we argue this? Could there be an oppressed position from whence any aggressive stance towards the public forbids itself? (I think there is!) For me this seems like putting the entire burden of transformational potential on the oppressed individual, enabling a position like: \"Well, the person did not object or introduce change, so the person implied consent.\"\nWill a public fight cause more harm being fought than it will save after introducing change? And who are we to calculate this beforehand?\n\n\t\n\t\tNote\n\tcreated by Aron Petau on Sunday 05.

Epistemic injustice: Power and the ethics of knowing. Oxford University Press, 2007.\nPublication\n\n\n\nWorin unterscheiden sich inferentialistische von nicht-inferentialistischen Theorien der testimonialen Erkenntnis (d.h. des Wissens durch das Zeugniss andere)?\n\nInferentialistische Theorien gehen davon aus, dass die eigentliche Inferenz, also die Generierung eines neuen Epistems im Subjekt stattfindet. Konkret heisst dass, dass Ich die Aussage P einer dritten Person erst in irgendeiner Weise vor mir selbst rechtfertigen muss, bevor ich sie selbst verwenden kann. Ist die Aussage nun 2 + 2 = 4, muss ich also mit allen mir zur Verfügung stehenden Mitteln selbst überprüfen, ob diese Aussage Wahrheits- und Kohärenzkriterien erfüllt. Ich muss also beispielsweise über darunterliegende Axiome, die mir bekannt sind, die Aussage extern (ausserhalb von Person X hat das gesagt, also kann Ich das glauben) überprüfen. Im simplen Beispiel also konkret das Ergebnis berechnen. Wenn man so will, liegt also immer die “Beweislast” für meine eigenen Episteme bei mir und ich kann diesen Beweisaufwand nur begrenzt auslagern. Eine sehr direkte Folge davon wäre, dass jeglicher Erkenntnisgewinn mit erheblicher, bewusster oder unbewusster Arbeit verbunden ist.\nDies wäre die wahrscheinlich logisch stringentere Theorie, gegen sie spricht aber die Phänomenologie eines Erkenntisgewinns. Eine Erkenntnis kommt uns oft vor wie ein “Heureka” Moment, wir “finden” sie, plötzlich ist sie da und wir können mit ihr arbeiten.\nEine nicht-inferentialistische Theorie legt ebendiese Beweislast nicht im Subjekt an, ich habe eine Erlaubnis, oder besser, ein Recht auf a-priori Annahme der Richtigkeit der Aussage. “Person X hat mir P gesagt, also kann ich P verwenden” ist nun valide und bedarf erstmal keiner weiteren Überprüfung auf Richtigkeit. Diese Argumentationslinie ist deutlich kompatibler mit der phänomenologischen Erfahrung einer Erkenntnis vim Alltag. Wir stoßen aber auf deutlich größere Probleme, wenn wir uns fragen, woher eigentlich unser Recht auf Wahrheitsannahme von Drittaussagen kommt. Klar, 2+2=4, weil der Prof das an die Tafel geschrieben hat, ist die “schlechtere” Begründung als zu sagen, dass das Ergebnis aus gewissen mathematischen Axiomen deduziert wurde.\n\nFormulieren Sie jeweils einen Einwand gegen beide Theorien.\n\nWir befinden uns also nun in der Spannung der phänomenalistischen “Heureka” Erfahrung des Findens von Epistemen (in nicht-inferentiellen Systemen) und dem Problem der schwachen Justifizierung von Aussagen gegenüber der erhöhten Stringenz eines epistemischen Systems, dass externe (logische, probabilistische, normative etc.) Gründe für Aussagen zur Verfügung stellt, aber einen schier unüberwindbaren rechnerischen Aufwand darstellt. Auch das Problem der ersten Begründung bleibt bestehen. Angenommen, ich weiß noch nichts, habe bisher null Episteme gesammelt, wie wird das erste Epistem, das ich finde, begründbar sein?\n\nWorin besteht doxastische Verantwortung (doxastic responsibility) nach F und Ihrer eigenen Meinung nach.\n\nDoxastische Verantwortung ist die Verantwortung für die Begründbarkeit des eigenen Nezwerkes aus Epistemen. Wenn mich also jemand fragt: Warum glaubst du das?, ist es sozial im Allgemeinen erwartbar, dass ich darauf eine Antwort liefern kann. Und wie wir eben schon am Beispiel der Begründung für 2+2=4 gesehen haben, scheint es hier “bessere” und weniger gute Gründe zu geben, das heisst, eine Person kann zur Verantwortung gezogen werden, unzureichend begründete Episteme fallen zu lassen und eine gewisse Grenze zu ziehen, eine mindest erwartbare Begründung. Diese kann sehr wahrscheinlich nicht universell formuliert werden. Eine Regel wie: Alle Bürger dürfen nur noch Aussagen weiterverwenden, denen sie eine mindestens 90-prozentige Wahrheitswarscheinlichkeit attestieren, ist aus diversen Gründen problematisch.\nFrickers Auffassung Doxastischer Verantwortung ist insofern speziell, als dass sie eine deutliche Verbindung moralischer Verantwortung (die wir offensichtlich alle in irgendeiner Form tragen) und Doxastischer Verantwortung sieht.

Sadly, we used beta functionality from the older \"Google Assistant\" Framework, which got rebranded months after by Google into \"Actions on Google\" and changed core functionality requiring extensive migration that neither Chris, my partner in this project, nor I found time to do.\nNevertheless, the whole Chatbot functioned as a meditation player and was able to graph and store recorded sentiments over time for each user.\nAttached below you can also find our final report with details on the programming and thought process.\n\n Read the full report\n\n\n Look at the Project on GitHub\n\n\n\t\n\t\tNote\n\tAfter this being my first dip into using the Google Framework for the creation of a speech assistant and encountering many problems along the way that partly found their way also into the final report, now I managed to utilize these explorations and am currently working to create Ällei, another chatbot with a different focus, which is not realized within Actions on google, but will rather be getting its own react app on a website.\n\n\n"},{"url":"https://aron.petau.net/project/critical-epistemologies/","title":"Critical Epistemology","body":"Forum entries from the Seminar: Critical Epistemologies\nOn Anderson: Institutions\n\n\t\n\t\tNote\n\tSource Text: Epistemic Justice as a Virtue of Social Institutions\nElizabeth Anderson (2012) Epistemic Justice as a Virtue of Social Institutions, Social Epistemology, 26:2, 163-173,\nDOI: 10.1080/02691728.2011.652211 Publication\n\n\nThe text by Anderson helped shed light on a few issues I stumbled over with Frickers Account. On top of the various issues I and seemingly others have with her virtue-based approach, I think a utilitarian angle is worth considering. That would be: okay, I accept that people can help fight injustice by realising their privilege, showing restraint, silencing themselves, and adopting the benevolent listening approach. I think that is a practical, virtuous, and realistic endeavour.\nBut is it the effective path to alleviating structural injustice? I think not, and initially, that is a major reason I discarded Fricker’s approach, although I saw merit. I have similar concerns to Anderson in the scalability of virtues. Virtuous behavior might help my personal well-being, it gives me normative elevation and might even further the quality of relationships I have. But is it applicable to society, is it enough to counteract structural injustice?\nWell, maybe, assuming that:\n\nEveryone realizes their privilege,\nEveryone concludes that justice is the right goal,\nUpon deciding to adopt a virtuous stance, everyone at least moderately succeeds in practicing what they preach.\n\nI think, for society, the same society that came up with patriarchy in the first place, external pressure, some measure independent of the convictedness of the subjects is needed.\nAnderson made the powerful point of: “Anything that works, goes”, which took me some time to appreciate. I am always angry when I get told to keep my shower to a minimum or stop using plastic straws when I know exactly that my using less water is nothing compared to the institutionalized practice of Coca-Cola putting water into bottles. I feel like it is unjustified to ask me to save water while others triple their output, for performance.\nThe same thing applies to Epistemic injustices. It strikes me how much energy it costs to keep up virtuous behavior individually and how little effect there is to show for it. I do not believe in “trickling up” where institutions will eventually adopt individual practices.\nIs Fricker thereby less right in her point? No, it adds up, as an entire population showering shorter adds up to lots of water saved.\nAnderson also points out how locally innocent biases can create injustice on a “macro” scale. Another indicator for me is that local virtue is not the sole solution, as it can still feed and sustain a system enforcing epistemic injustice.\nI still have doubts about what to do now with my ideas, on how the world looks that I want. I lack the imagination of seeing a world that is epistemically just, and it is hard to strive for something one cannot even imagine. The system is inherently leaning toward inequality, if I try to balance something on a needle, it will only go well so long, before small imbalances create chain reactions and the object should be called unstable. Should we even succeed in “resetting” society, creating equal participation for each subject, how will it remain just? Is Justice always a conjunct of Equality? Are there ways to achieve real Justice without needing equality?\n\n\t\n\t\tNote\n\tcreated by Aron Petau on Tuesday 14. July 2020, 17:45\n\n\nOn Medina, the informant and the inquirer\n\n\t\n\t\tNote\n\tSource Text: Dr. José Medina (2012) Hermeneutical Injustice and Polyphonic Contextualism: Social Silences and Shared Hermeneutical Responsibilities, Social Epistemology, 26:2, 201-220, DOI: 10.1080/02691728.2011.652214\nPublication\n\n\nMy biggest takeaway here was that, as I tried to hint at in an earlier comment,\nWhenever we talk about justice, this necessarily refers to a relational concept, where everybody has a double role to ensure successful communication. Medina calls these the inquirer and the informant. So, every individual has to make sure to act to her capacity as an epistemologically sound knowledge-acquiring agent (the inquirer). This would involve knowing when and how to falsify/qualify statements, making inferences about the theory of mind, and generally comparing different statements. The other role is the informant, where the individual should have the capacity to function as an object in an inquiry by another.\nVery roughly this can, I think, be compared to any good communication model, where there are a listener and a speaker, and both have to function. What was new here, or at least came out more clear is that it not only depends on the capacity of both of these roles on the subject, but it is also directly dependent on the “other”, the agent opposite of the subject. We may call this other society later but it helps me to visualize the other as an individual nonetheless. Where the analogy to communication now fails, in my opinion, is this cross-dependence, where an agent does not fully determine her capacity to act both as an inquirer and as an informant, it is co-determined by the “other”. So, if I, as an “other”, listen to someone's statements, and I fail or refuse to understand the epistemic content of the message, I am not only impairing my epistemic agency, but I also hurt the epistemic agency of the subject. Maybe obvious to most, but this thought struck me as being exactly the point of leverage for dysfunctionalities in power relations.\nAlso argued convincingly in the paper was that these are distinct and independent agencies, which can be impairing an individual separately.\nOverall, the Medina text was incredibly helpful after the somewhat confusing Fricker text that felt incomplete and left a lot of questions for me. The medina text picked up all my initial doubts, that I couldn't properly formulate, and many more, while still holding to the general framework of Fricker.\nAlthough I was not convinced by the Fricker Text, I tend to think the strategy:\n\"When in doubt, give the subject full epistemic credibility\"\nIs a good strategy that might alleviate a lot of issues regarding functions of power, and hierarchy, but also further, it might be a good counter for things as our confirmation bias, expectation bias and many individual errors that we could minimize by constantly exposing ourselves to falsifiability through others (voluntarily). Sounds like science applied to agency to me.\n\n\t\n\t\tNote\n\tcreated by Aron Petau on Thursday 09.

Jaggar (1989) Love and knowledge: Emotion in feminist epistemology, Inquiry, 32:2, 151-176, DOI: 10.1080/00201748908602185\nPublication\n\n\nI found Jaggar to be a very wholesome read, it was the perfect amount of grounded argumentative structure and felt very connected as a whole. This was, together with the ideas from Lugones the best and most fruitful paper for me.\nOn outlaw emotions:\nFirst, I hate the term, I think it’s placative and fails to frame the (actually nice) idea behind it.\nOutlaw Emotions are all those emotions incompatible with the dominant norms. That’s a huge field to cover, among feminist emotions they would also encompass emotions that are irrational or “faulty”. So, Jaggar does the term Justice by saying, some, but not all Outlaw Emotions are Feminist emotions. To make this evident, just think of a murderer's joy for killing, it is of no feminist interest to dissect, yet it is against dominant values. So, experiencing Outlaw emotions is a (probably) necessary, but not sufficient condition for feminism. The incompatible emotion serves to create discourse and change.\nJaggar convincingly shows how emotions have a direct influence on beliefs and can validly constitute evidence, while simultaneously validly influencing values in a similar manner.\nWhen we talk about dominant/alternative norms, we already endorse hierarchy in society. We acknowledge its existence, simply by identifying the dominant norm. I am not quite sure what exactly Jaggar proposes we should do with the hierarchy structures in society. Explicitly I can read: Subcultures rejecting dominant norms should be formed, to create counterbalances and a somewhat fair discourse over the topic.\n“How can we determine which outlaw emotions are to be endorsed or encouraged and which rejected? In what sense can we say that some emotional responses are more appropriate than others? What reason is there for supposing that certain alternative perceptions of the world, perceptions informed by outlaw emotions, are to be preferred to perceptions informed by conventional emotions? Here I can indicate only the general direction of an answer, whose full elaboration must await another occasion. I suggest that emotions are appropriate if they are characteristic of a society in which all Human Life (and perhaps some nonhuman life, too) thrive, or if they are conducive to establishing such a society.”\nTo me this passage sounds sketchy at best, there is no indication of how to successfully separate appropriate from inappropriate emotions. Roughly, I read this part as: emotions are warranted iff they increase the balance of power. (equivalent to minimizing the height of the hierarchy) I would love to get to read this “other occasion” because it seems indefensible to me to formulate a norm that states: Accept only emotions which eliminate/diminish norms.\nThe idea roughly resembles Rawls's Minimax Principle, where a policy should be implemented iff the benefit for the most disadvantaged is highest.\nAnother thing I found helpful is her reformulation of what norms do:\n“Dominant Norms tend to serve dominant interests”\ntil here nothing new, this is a tautology for me, I understand norms as identical to dominant interests, that’s literally what norms are.\nIs an alternative, suppressed norm even thinkable? Isn't it inherent in a norm that it be the dominant one?\nBut then, after that: \"Whatever our color / gender / class / sexual orientation, we are likely to adopt the dominant value of racist, classist, homophobe, misogynistic white men.\"\nThis was rather helpful to me, as it reframes the “act” of oppression as the “likelihood of value distribution” being skewed in your favor, making everybody’s values more likely to be similar to yours. This nicely illustrates how a system can be hierarchical and oppressive, without anybody actively, intentionally “acting oppressive”, while still perpetuating oppression. I'm\nnot saying everybody is acting unintentionally oppressive, but it is always hard to imagine for me to picture \"White Men\" forming a group and collectively deciding on who to hate this coming season, Conceptually separating \"being oppressed\" and \"oppressing\" into phenomena\nwithout necessary inherent causal relation makes sense to me here.\n\n\t\n\t\tNote\n\tcreated by Aron Petau on Tuesday 23.

All of this leads to a huge industry, Germany being especially involved, using loads of virgin plastic.\nWhat can be done about it?\nWe can design our products to last longer, we can also print recycling labels on them so they do not have to get burned after their first life. We can take care to only print functional objects, not just fun toys nobody uses.\nYet, none of that prevents the use of virgin plastics. If you buy a spool of filament, there are some recycled options, but usually at twice the price at worse quality. No wonder recycled filament fails to convince the masses. It is mostly a fun thing YouTubers can pursue, not a valid commercial process.\n\n\nIn my opinion, the core problem is the nonexistent economic feasibility of a proper recycling process. Identifying the exact material of a piece of trash is a very hard problem, definitely not solved yet. So why do we mix the plastic up in the first place? There is a general willingness of people to recycle, but the system for it is missing.\nThe Master Plan\nI want to get people to wash and separate their trash for me, which are the most expensive steps in the recycling process. There is a willingness to take the extra step, and even if just my mom collects bottle caps for me, that is more than I can realistically use up.\nThis only really works when I am thinking in a local and decentral environment.\nThe existing recycling facilities clearly will not be able to provide 200 different containers for 200 different types of plastic.\nStarting the process with clean and sorted materials, like bottle caps (HDPE) or failed prints (PET-G), I start off with an advantage.\nNow I have to take apart the trash into evenly sized particles.\nMeet:\nThe Shredder\nWe built the Precious Plastic Shredder!\n\nWith these awesome open-source drawings, I was able to cobble together my very own very dangerous plastic shredder.\nAfter finding some way to drive this massive axis, I feed the beast and hopefully get tiny pretty uniform plastic bits that are ready to begin the cycle of life anew.\nThe solution for the motorization was an old and used garden shredder that still had an intact motor and wiring.\nWe cut it in half and attached it to the shredder box.\n\n\nAfter replacing the weak force transmission screw for an industrial coupler, we were ready to try it out. Obviously, there are still security concerns in this prototype, a proper hopper is already being made.\nNevertheless, we are confident that this shredder will be able to deal with the light sorts of plastic we are thinking of.\nAs you can see, I am now able to produce awesome confetti but to do more with the plastic flakes I have to extrude them.\nMeet the Filastruder\nThis is the Filastruder, designed and made by Tim Elmore, in an attempt to create the cheapest viable way to extrude plastic. The biggest cost issue is the tight industrial tolerances in thickness that have to be adhered to. This is in essence what separates good from the bad filament. The industry standard nowadays is at +-0.03mm. Hard to achieve on a DIY setup, but not unheard of. The setup, like any bigger industry equivalent, consists of a motor pressing plastic pellets through a heated screw, extruding molten plastic at the end through a nozzle, and setting the diameter. The leftmost machine is responsible for winding the filament properly onto a spool.\nHere you can see the extrusion process in action.\n\n\nThe Filastruder is controlled by an Arduino and is highly configurable. The laser sensor visible in the video is already working, but I am missing more direct control over the diameter of the filament.\nWhen it all really comes down to the single variable of the filament diameter responsible for the quality of my recycled project, a simple Machine Learning optimization directly jumps at me: I have a few variables like winder speed, extrusion speed, heat, and cooling intensity. These variables can be optimized on the fly for an exact diameter. This is actually roughly how virgin filament is produced, commercial facilities just manage much faster.\n\nSo far, I am aware of a few companies and academic projects attempting this process, but none of them manage to get either the quality or the price of other products available. Automatization does not just take out jobs away, I think it can also be a helpful tool, for example tackling environmental issues such as this one.\nThis project is very dear to my heart and I plan to investigate it further in the form of a master thesis.\nThe realization will require many skills I am already picking up or still need to work on within the Design and Computation program.\n\n Reflow Filament\n\n\n Perpetual Plastic Project\n\n\n Precious Plastic Community\n\n\n Filamentive Statement on why recycling is not feasible in their opinion\n\n\n Open source filament diameter sensor by Tomas Sanladerer\n\n\n Re-Pet Shop\n\n"},{"url":"https://aron.petau.net/project/beacon/","title":"BEACON","body":"BEACON: Decentralizing the Energy Grid in inaccessible and remote regions\nAccess to Electricity is a basic human right. At first, that may seem over the top, but if one stops to think what all the little tasks that electricity can indirectly handle for us (lightning, laundry, cooking, freezing, heating, entertaining…) would consume in time and effort if we had to perform them manually, this idea becomes very clear. There are globally around 1 billion people without tier 2 access to electricity.\nSDGS Goal 7\n\nPeople only know the intensity of labor that goes into everything when there is no electricity. And it is not even only about convenience, electricity is an enormous lifesaver in any number of scenarios, think just of hospitals or mobile phone networks that would be rendered completely useless without it. So we can easily agree on a need, a demand for electricity globally, for every person. But what about the supply? Why is there 1 billion undersupplied?\nThe Answer: missing profitability. It would be a charity project to supply every last person on earth, not a profitable one. And while charitable projects are noble and should be pursued, the reality within capitalism shows that this is not the way it is going to happen.\nBut what if we could come up with technology, or rather, a communal structure, that enables us to supply profitably, and still adapt to both, the difficult external factors (weather issues, remoteness, altitude, etc.) and the smaller purses of the undersupplied?\nLocation\nTowards the end of 2018, I spent 4 months in northern India, on a research project with the IIT Kharagpur.\nThe goal was to work on one of the 17 UN-defined sustainable development goals – electricity.\nWorldwide, an estimated 1 billion people have no or insubstantial access to the grid.\nSome of them live here, in the Key Monastery in the Spiti Valley at around 3500 meters altitude.\n\n\n\nThis is Tashi Gang, a village close to the Monastery. It houses around 50 people and only has road access during 3-4 months in the summer. For the rest of the time, the people rely on first aid services by helicopter, which can only be called with a working cell phone tower.\n\nThe Project\nIn an environment reliant on hydro-energy and solar (diesel transport is unreliable due to snowed-in mountain roads), over 6 months of snowy winter, frequent snowstorms, and temperatures of up to -35°C, securing the grid is hard.\nOur way to tackle the issue was to reject the in the western society very established notion of electricity as a homogenous product with centralized production and instead researched the possibilities of a predictive, self-correcting, and decentral grid.\nBy prioritizing energy usage cases, instead of a full blackout during a storm, essential functions like radio towers and hospitals could be partially powered and maybe stay functioning. The binarity of either having electricity or not would be replaced by assigned quantities and timeslots, in a collective effort to be mindful and distribute the electricity necessity-based.\nThe ultimate vision was a live predictive electricity market, where people could even earn money by selling their allotted, but not needed electricity.\nTo gauge feasibility, I conducted several psychological acceptance studies and collected data on local electricity demands.\nI simulated a typical day of electricity demand in the Key monastery and the surrounding villages and mapped out the potential to install cost-efficient smart microgrid controllers enabling such an accurate and predictive behavior.\nThe smart grid operator boxes available here in Germany cost several hundred, with installation several thousand Euros, not a feasible solution for the Indian population. Instead, we wanted to use Raspberry Pi's, which are interconnected through ethernet cables or local mesh networking.\nResearch\n\nData Collection\nBuilding a questionnaire and visiting public schools during their English Classes, I had the chance to speak to a range of teenagers, answering questions about the state of electricity in their homes, generating more data than I could have accomplished running from door to door without any skills speaking local dialects. The questionnaire was as scientific as I could make it in such a situation and geared towards finding the type and number of electric devices in the homes and estimating typical usage scenarios.\nWith a total of 145 participants from more than 6 different schools and roughly 4 different districts, all located in the Indian part of the Himalayas, the findings are as follows:\nThe participants range from 11 to 53 years, with an average of 17 years.\nThe average household has 6 members with an average of 5 smart devices. Only 2 percent of the Households had not a single smart device, but at the same time, only 42 percent had direct or indirect access to a laptop or computer. So the main body of smart devices consists of smartphones with a negligible portion of tablets.\nThe average total amount of electrical devices is around 11 electrical appliances per house.\nSubjective Quality Rating on a scale of 1 to 10:\n\nAverage quality in summer: 7.1\nAverage quality in monsoon: 5.6\nAverage quality in autumn: 7.1\nAverage quality in winter: 4.0\n\nSo, as you would expect, during winter, but also when it rains, the felt quality drops by more than 30 percent on average.\nAs for the daily supply time, the average sits at 15.1 hours out of 24, meaning the people have electricity only for 62.9 percent of the time, some, as for example the people in Diskit only have a sad 4 hours of daily access. On top of that, this estimation does not account for the snowfalls in Spiti for example, where it is not uncommon to experience 3 consecutive days of powercut or more.\nAs the Power Meter is supplied by the government, a solid 82 percent of the houses have a working power meter, if one assumes that the 13 percent who did not know whether they have a power meter, do have one, we can say that around 95% of the houses have a power meter.\nAnother goal of the studies was to find out what would incline people to be caring and sharing with the available electricity, something rather unimaginable here in Germany.\nIn general, the uninformed openness to delaying usage of electricity on a scale of 1-10 was around 5.5, with the additional information that a smart delay would cause an overall price reduction, the acceptance went up to 6.9, a good 14%. This implies that people would be a lot more inclined to give up conveniences if the benefits have a direct impact on them.\nSimulation\nAfter collecting all the estimated electric appliances of the local population, I simulated the use of 200 Solar Panels with 300Wp each, once for simultaneous electricity use, and once for mitigated electricity peaks through smart optimization and electricity usage delay.\n\n\nAlthough solar is definitely not the optimal choice here and generates lots of issues with energy storage and battery charging at negative degrees, we figured that this was the way to go for the project.\nAnd as you can see, optimizing peak usage can improve solar from generating only one-fifth of the demand in winter to about half the demand in winter. Keeping in mind here, that the added solar farm was only intended to supply additional energy and not replace existing solutions, such a \"small\" farm would be a real lifesaver there and optimize the limited space in extremely mountainous terrain.\nClosing words\nThere are to sides which the problems can be tackled: we can bring the total energy production up, by adding more panels or electricity by other means, but we can also try and bring the total demand down. This is to be achieved by investing strictly in the most energy-efficient appliances. Even replacing older, not-so-efficient appliances might sometimes be of use.\nBut ensuring efficient use is not the only way to bring down the overall demand.\nAs introduced as core ideas for the whole project, sharing and delaying will prove immensely useful. How so?\nBy sharing, we mean a concept that is already widely applied in the relevant areas. What to do in a Village that has no access to water? Will we send each household out to the faraway river to catch water for their family? Or would we join hands in a community effort to dig a central well used by everyone?\nSo, when we look at sharing electricity, how would we apply the concept? We take the appliances that consume the most energy individually and scale them up in order to increase efficiency. For example, in our case, that is most applicable to electric heating. If we manage to heat central community spaces available for everyone, naturally, fewer individual rooms will have to be heated. Similarly, one could declare a room as a public cinema, where people come together and watch Tv on a big Projector. Twice as fun, and conserving a great deal of energy again. Such ideas and others have to be realized in order to be able to match the total demand with the available supply.\nSadly, the project was never taken up further, and the situation for the people in the Spiti Valley has not improved. Two years ago, a road directly through the mountains was finished, making the population hopeful for an increase in tourism, increasing the chances of the economic viability of improved solutions.\nI spent my time there in the function of a research intern, having no real say in the realization of the project. The problem remains, and I still think that decentral solutions look to be the most promising for this specific location. Of course, the Himalayas present a bit of an extreme location, but that doesn't change the fact that people live there and have a basic human right to electricity.\n"},{"url":"https://aron.petau.net/project/cad/","title":"3D Modeling and CAD","body":"3D Modeling and CAD\nDesigning 3D Objects\nWhile learning about 3D printing, I was most intrigued by the possibility of modifying and repairing existing products. While there’s an amazing community with many good and free models available, I naturally reached a point where I couldn’t find what I was looking for already designed. I realized that this is an essential skill for effectively operating not just 3D printers, but really any kind of productive machine.\nSince YouTube was where I learned everything about 3D printing, and all the people I looked up to there were using Fusion 360 as their CAD program, that’s what I got into.\nIn hindsight, it was a pretty good choice — I fell in love with the possibilities that parametric design gives me.\nBelow you’ll find some of my designs.\nThe process is something I deeply enjoy and want to explore even more.\nThrough trial and error, I’ve already learned a lot about designing specifically for 3D printing. But I often feel that I lack a deeper understanding of aesthetic considerations in design.\nI want to broaden my general ability to design physical objects, something I hope to gain during my master’s.\n\n\n\n\n\n\n\nCheck out more of my finished designs in the Prusaprinters (now Printables) Community\n\n My Printables Profile\n\n3D Scanning and Photogrammetry\nBesides coming up with new objects, incorporating the real world is also an interest of mine.\nInteraction with real objects and environments\nIn the last few years, I played around with a few smartphone cameras and was always quite sad that my scans were never accurate enough to do cool stuff with them.\nI couldn’t really afford a proper 3D scanner and had already started cobbling together a Raspberry Pi camera with a cheap TOF sensor.\nThat setup is simple, but not nearly as precise as a laser or LiDAR sensor. Then Apple released the first phones with accessible LiDAR sensors.\nRecently, through work at the university, I got access to a device with a LiDAR sensor and started having fun with it.\nSee some examples here:\n \n \nThis last one was scanned with just my smartphone camera. You can see that the quality is notably worse, but considering it was created with just a single, run-of-the-mill smartphone sensor, I think it’s still pretty impressive — and will certainly help democratize such technologies and capabilities.\n \nPerspective\nWhat this section is supposed to deliver is the message that I am currently not where I want to be when navigating the vast possibilities of CAD.\nI feel confident enough to approach small repairs around the flat with a new perspective, but I still lack technical expertise when it comes to designing collections of composite parts that have to function together. I still have lots of projects half-done or half-thought — and one major reason is the lack of critical exchange within my field of study.\nI want more than designing figurines or wearables.\nI want to incorporate 3D printing as a method to extend the abilities of other tools — to serve mechanical or electrical purposes, be food-safe and engaging.\nI fell in love with the idea of designing a toy system. Inspired by Makeways on Kickstarter, I’ve already started adding my own parts to their set.\nI dream of my very own 3D printed coffee cup — one that is both food-safe and dishwasher-safe.\nFor that, I’d have to do quite a bit of material research, but that only makes the idea more appealing.\nI’d love to find a material composition incorporating waste, to stop relying on plastics — or at least on fossil-based ones.\nOnce in Berlin, I want to connect with the people at Kaffeform, who produce largely compostable coffee cups incorporating a significant amount of used espresso grounds (albeit using injection molding).\nThe industry selling composite filaments is much more conservative with the percentage of non-plastic additives, because a nozzle extrusion process is much more error-prone.\nStill, I would love to explore that avenue further and think there’s a lot to be gained from looking at pellet printers.\nI also credit huge parts of my exploration into local recycling to the awesome people at Precious Plastic, whose open source designs helped me out a lot.\nI find it hard to write anything about CAD without connecting it directly to a manufacturing process.\nAnd I believe that’s a good thing. Always tying a design process to its realization grounds the process and gives it a certain immediacy.\nTo become more confident in this process, I still need more expertise in designing organic shapes.\nThat’s why I’d love to dive deeper into Blender — an awesome tool that in my mind is far too powerful to learn solely through YouTube lessons.\nSoftware that I have used and like\n\n AliceVision Meshroom\n Scaniverse\n My Sketchfab Profile\n 3D Live Scanner for Android\n\n"},{"url":"https://aron.petau.net/project/printing/","title":"3D printing","body":"\n\n\n \n \n \n \n \n \n \n \n \n \n A plant propagation station now preparing our tomatoes for summer\n \n \n \n \n \n \n \n \n \n \n \n We use this to determine the flatmate of the month\n \n \n \n \n \n \n \n \n \n \n \n A dragon's head that was later treated to glow in the dark.\n \n \n \n \n \n \n \n \n \n \n \n This was my entry into a new world, the now 10 years old Ender 2\n \n \n \n \n \n \n \n \n \n \n \n I made some lithophanes, a process where the composition and thickness of the material are used for creating an image.\n \n \n \n \n \n \n \n \n \n \n \n This is my second printer, a Prusa i3 MK3s.\n \n \n \n \n \n \n \n \n \n \n \n This candle is the result of a 3D printed plastic mold that I then poured wax into.\n \n \n \n \n \n \n \n \n \n \n \n An enclosure for my portable soldering iron\n \n \n \n \n \n \n \n \n \n \n \n A lamp screen design that particularly fascinated me, it effortlessly comes from a simple 2D spiral shape.\n \n \n \n \n \n \n \n \n \n \n \n A custom-built printer enclosure made up of 3 Ikea Lack tables and around 3 kgs of plastic.\n \n \n \n \n\n3D Printing\n\n\n3D Printing is more than just a hobby for me\nIn it, I see societal changes, the democratization of production, and creative possibilities.\nPlastic does not have to be one of our greatest environmental problems if we just choose to change our perspective and behavior toward it.\nPlastic Injection molding was one major driving force for the capitalist setting we are in now.\n3D Printing can be utilized to counteract the production of scale.\nToday, the buzzword 3D Printing is already associated with problematic societal practices, it is related to \"automatization\" and \"on-demand economy\".\nThe technology has many aspects to be considered and evaluated and as a technology, many awesome things happen through it and on the same page it fuels developments I would consider problematic.\nDue to a history of patents influencing the development of the technology, and avid adoption of companies hoping to optimize production processes and margins, but also a very active hobbyist community, all sorts of projects are realized.\nWhile certainly societally explosive, there is still a lot going for 3D Printing.\n3D Printing means local and custom production.\nWhile I do not buy the whole “every household is going to have a machine that prints what they need right now at the press of a button”, I do see vast potential in 3D Printing.\nThat’s why I want to build my future on it.\nI want to design things and make them become reality.\nA 3D Printer lets me control that process from start to finish. Being able to design a thing in CAD is not enough here, I also need to be able to fully understand and control the machine that makes my thing.\nI started using a 3D Printer in early 2018, and by now I have two of them and they mostly do what I tell them to do.\nI built both of them from kits and heavily modified them.\nI control them via octoprint, a software that, with its open and helpful community, makes me proud to use it and taught me a lot about open-source principles.\n3D Printing in the hobbyist space is a positive example where a method informs my design and I love all the areas it introduced me to.\nThrough it, I felt more at home using Linux, programming, soldering, incorporating electronics, and iteratively designing.\nI love the abilities a 3D Printer gives me and plan on using it for the recycling project.\nDuring the last half year, I also worked in a university context with 3D printers.\nWe conceptualized and established a \"Digitallabor\", an open space to enable all people to get into contact with innovative technologies.\nThe idea was to create some form of Makerspace while emphasizing digital media.\nThe project is young, it started in August last year and so most of my tasks were in Workgroups, deciding on the type of machines and types of content such a project can provide value with.\nRead more about it on the Website:\nDigiLab Osnabrück\nLooking forward, I am also incredibly interested in going beyond polymers for printing.\nI would love to be able to be more experimental concerning the material choices, something rather hard to achieve while staying in a shared student flat.\nThere have been great projects with ceramics and printing, which I certainly want to have a deeper look into.\nOne project I want to highlight is the evolving cups which impressed me a lot.\nEvolving Objects\nThis group from the Netherlands is algorithmically generating shapes of cups and then printing them on a paste extruder with clay.\nThe process used is described more here:\nThe artist Tom Dijkstra is developing a paste extruder that can be attached to modify a conventional Printer and I would very much love to develop my version and experiment with printing new and old materials in such a concept printer.\nPrinting with Ceramics\nThe Paste Extruder\nAlso with regards to the recycling project, it might make sense for me to incorporate multiple machines into one and let the printer itself directly handle pellet- or paste-form.\nI am looking forward to expanding my horizon there and seeing what is possible.\nCups and Tableware are of course just one sample area where a backtrack toward traditional materials within modern manufacturing could make sense.\nThere is also more and more talk of 3D Printed Clay- or Earth homes, an area where WASP is a company I look up to.\nThey built several concept buildings and structures from locally mixed earth, creating some awesome environmentally conscious structures.\nAdhering to principles of local building with locally available materials and taking into account the infamous emission problem within the building industry has several great advantages.\nAnd since such alternative solutions are unlikely to come from the industry itself, one major avenue to explore and pursue these solutions are art projects and public demonstrations.\nI want to explore all these areas and look at how manufacturing and sustainability can converge and create lasting solutions for society.\nAlso, 3D Printing is directly tied to the plans for my master's thesis, since everything I manage to reclaim, will somehow have to end up being something again.\nWhy not print away our waste?\nNow, after a few years of tinkering, modifying and upgrading, I find that I did not change my current setup for over a year.\nIt simply works and I am happy with it.\nSince my first beginner's printer, the failure rates are negligible and I have had to print really complex parts in order to generate enough waste for the recycling project.\nGradually, the mechanical system of the printer shifted from an object of care to simply a tool that I use.\nIn the last years, hardware, but especially software has matured to a point where, at least to me, it tends to be a set-and-forget situation.\nOn to actually making my parts and designs.\nRead more about that in the post about CAD\n"},{"url":"https://aron.petau.net/","title":"Home","body":"\nWelcome\nto the online presence of Aron Petau.\n\n\n\nI use he/him pronouns and am based in Berlin, Germany.\nI am a tinkerer,
