This was an idea that occupied my sketchbook for a while: a modular lamp whose units would light up upon contact with one another. I had tricky standards for this project:
- Must be as low cost as possible (no soldering/laser cutting necessary)
- Similar to actual tetris so units may be rearranged into different orders/configurations while remaining lit up
- Use up some of the extra materials I have lying around
- Have a simple battery design (a 3V coin battery powers this)
- Have a simple on/off switch
- Enable selective lighting while remaining connected (so some cubes will be on while others are off)
- Use magnets so that units are secured to one another
- The only thing I couldn’t incorporate was a replaceable battery system 🙁
The idea is based of this product by thinkgeek, which costs $50 more than I wanted to spend, but I got my version’s cost down to $3.27 (though I did happen to have random materials lying around)!
