Kartabot
Kartabot, or “brushbot”, is extremely simple and cute!
If you have the parts and a spare toothbrush, you can make your own in just a few minutes!
Materials
- 2 solar cells in series
- vibration motor from a cell phone
- toothbrush
Solar cells are very fragile, it’s just a thin silicon sheet. To fix that, I’ve tinned them on the back side.
