## 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.
|
||||
|
||||
## Propellant
|
||||
## Treibstoff
|
||||
|
||||
The car takes either **Super** (95), **Super Plus** (98) or **E10**.
|
||||
{: .notice--danger}
|
||||
{% alert(note=true) %}
|
||||
Das Auto fährt mit **Super (95)**, **Super Plus (98)** oder **E10**.
|
||||
{% end %}
|
||||
|
||||
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.
|
||||
Bitte tanke **immer voll**, sonst weißt du nicht, wie weit du noch kommst.
|
||||
|
||||
Please remember to reset the meter after filling up.
|
||||
{: .notice--danger}
|
||||
{% alert(note=true) %}
|
||||
Vergiss nicht, den Tageskilometerzähler nach dem Tanken **zurückzusetzen**.
|
||||
Drücke dazu den mittleren Knopf auf dem Armaturenbrett.
|
||||
{% end %}
|
||||
|
||||
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.
|
||||
Versichert ist das Fahrzeug für Fahrer*innen **über 25 Jahre** mit gültigem Führerschein.
|
||||
Die Versicherung ist eine **Teilkasko**, deckt also alles außer eigene Schäden am Fahrzeug.
|
||||
|
||||
## 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.
|
||||
Standardmäßig sind sie **nicht im Auto**, weil sie selten gebraucht werden – frag einfach danach, wenn du sie benötigst.
|
||||
Das System erkennt die zusätzliche Leistung automatisch.
|
||||
{% end %}

## Küche
|
||||
|
||||
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.
|
||||
{: .notice--info}
|
||||
{% alert(note=true) %}
|
||||
Das Gas kommt aus einer **standardisierten 5 kg-Grauen Gasflasche**, die du an fast jeder Tankstelle tauschen kannst.
|
||||
Eine Flasche ist im Auto – das reicht normalerweise **über einen Monat**.
|
||||
Wenn sie leer ist, einfach an der Tankstelle tauschen.
|
||||
{% end %}
|
||||
|
||||
Kitchen is fully equipped for 2 People.
|
||||
Die Küche ist **komplett für zwei Personen** ausgestattet.

{% end %}
|
||||
|
||||
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.
|
||||
Es gibt einen **leistungsstarken 12 V-Kühlschrank** (ca. 30 L), betrieben über das Solarsystem.
|
||||
Er kann auch während der Fahrt laufen und bei genug Sonne dauerhaft.

The bed is in the high roof and is 1.20m wide and 1.90m long.
|
||||
Das Bett befindet sich im Hochdach und misst **1,20 m × 1,90 m**.
|
||||
|

## Heating
|
||||
## Heizung
|
||||
|
||||
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.
|
||||
Der Bus hat eine **Gasheizung** für den Standbetrieb – **nicht während der Fahrt nutzbar**.
|
||||
Geregelt wird sie über einen **Thermostat** neben dem Bett.
|
||||
Zum Einschalten: Gasflasche öffnen, Ventil im Gaskasten aufdrehen.
|
||||
Die Heizung startet automatisch, wenn die Temperatur unter den eingestellten Wert fällt.
|
||||
|
||||
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.
|
||||
Ein **12 V-Lüfter** sorgt für Luftzirkulation, zusätzlich gibt es einen **tragbaren Ventilator**, der im Sommer meist ausreicht.

## How to rent
|
||||
## Wie man mietet
|
||||
|
||||
You can rent the van by sending me an email to [rent-ulli@aronpetau.me](mailto:rent-ulli@aronpetau.me)
|
||||
I will need the following information:
|
||||
Du kannst den Bus mieten, indem du eine Mail an [rent-ulli@petau.net](mailto:rent-ulli@petau.net) schickst.
|
||||
Bitte gib an:
|
||||
|
||||
- Your name
|
||||
- Your address
|
||||
- a copy of your drivers license
|
||||
- the dates you want to rent the car
|
||||
- Deinen Namen
|
||||
- Deine Adresse
|
||||
- Eine Kopie deines Führerscheins
|
||||
- Die gewünschten Mietdaten
|
||||
|
||||
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.
|
||||
Ich sende dir dann einen Mietvertrag, den du unterschreiben und zurückschicken musst.
|
||||
Danach vereinbaren wir eine Abholzeit.
|
||||
|
||||
## Costs
|
||||
## Kosten
|
||||
|
||||
The car costs 30€ per day, plus 0.10€ per km.
|
||||
This factors in my insurance and the taxes I have to pay.
|
||||
Der Mietpreis beträgt **30 € pro Tag** plus **0,10 € pro km**.
|
||||
Das deckt Versicherung und Steuern ab.
|
||||
|
||||
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}
|

{% alert(note=true) %}
|
||||
Schäden am Fahrzeug gehen zu deinen Lasten.
|
||||
Ein Totalschaden würde etwa **10.000 €** kosten – also bitte vorsichtig fahren.
|

### Designing 3D Objects
|
||||
### Gestaltung von 3D-Objekten
|
||||
|
||||
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.

## 3D-Scannen und Photogrammetrie
|
||||
|
||||
Besides coming up with new objects, incorporating the real world is also an interest of mine.
|
||||
Neben dem Entwerfen neuer Objekte interessiert mich auch die Integration der **realen Welt** in meine Arbeit.
|
||||
|
||||
### Interaction with real objects and environments
|
||||
### Interaktion mit realen Objekten und Umgebungen
|
||||
|
||||
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.

|
||||
|
||||
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.

# 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.

## 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.

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") }}
|
||||
|
||||
{{ 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.
|
||||

|

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.

## 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.

### 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.

|

<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>Umgesetzt in Unity, ist <strong>Ballpark</strong> ein Konzept für ein <strong>kooperatives 2-Spieler-Spiel</strong>, 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.<br />
|
||||
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.</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>

<content type="html" xml:base="https://aron.petau.net/de/project/plastic-recycling/"><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>
|
||||
<content type="html" xml:base="https://aron.petau.net/de/project/plastic-recycling/"><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>
|
||||
<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.

<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>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>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>

|
||||
<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>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.

<p>Umgesetzt in Unity, ist <strong>Ballpark</strong> ein Konzept für ein <strong>kooperatives 2-Spieler-Spiel</strong>, 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.<br />
|

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.</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>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>

<content type="html" xml:base="https://aron.petau.net/de/project/plastic-recycling/"><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>
|
||||
<content type="html" xml:base="https://aron.petau.net/de/project/plastic-recycling/"><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>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>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>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>Enjoy!</p>

<p>Umgesetzt in Unity, ist <strong>Ballpark</strong> ein Konzept für ein <strong>kooperatives 2-Spieler-Spiel</strong>, 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.<br />
|
||||
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.</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>

<h3 id="Making_my_own_beer">Making my own beer</h3>
|
||||
<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>

<content type="html" xml:base="https://aron.petau.net/de/project/plastic-recycling/"><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>

|

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>
|
||||
<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.

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>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.
