At its core, the course is about understanding through creating: introducing young learners to tangible technologies and encouraging them to shape the outcome with their own ideas and hands.\nThe Project\nOver three sessions (each lasting three hours), participants designed and built their own USB-powered LED lamp. Along the way, they soldered electronic components, modeled lamp housings in 3D, learned about light diffusion, and got a direct introduction to real-world problem solving. Every lamp was built from scratch, powered via USB — no batteries, no glue kits, just wire, plastic, and a bit of courage.\nThe children began by learning the basics of electricity through interactive experiments using the excellent Makey Makey boards. These allowed us to demonstrate concepts like conductivity, input/output, and circuitry in a playful and intuitive way. The enthusiasm was immediate and contagious.\nFrom there, we moved to the heart of the project: cutting open USB cables, preparing and soldering 5V LEDs, and designing enclosures for them. The soldering was always supervised, but each child did their own work — and it showed. There's something deeply satisfying about holding a working circuit you assembled yourself, and many kids expressed how proud they were to see their light turn on.\nDesigning with Tools — and Constraints\nFor 3D modeling, we used Tinkercad on iPads. While the interface proved very accessible, we also encountered its limits: the app occasionally crashed or froze under load, and file syncing sometimes led to confusion. Nonetheless, it provided a gentle, well-mediated entry point to CAD. Most kids had never touched 3D design software before, but quickly began exploring shapes, tolerance
