Today, I've come up with the proof that 7-year-old boys not only like ice, but are also interested in electrical circuits: especially when soldering is allowed to assist and in the end something moves. So we assembled our "Bristle-Bot" in about 30 minutes and immediately started against a dust mob.

Advertising block: the suggestion came from a book "Robot self-build" by Daniel Knox. (I do not receive any commission). 

For this project we are going to take advantage of supercapacitors to power a vibrobot. In other words, we are going to be using 15F capacitors to power vibrating motors to make robots which move around through vibrations. The basic model has an on/off switch and a charging port to allow it to be charged up between uses. The more advanced version also includes a small solar cell to let it be charged by the sun when not being used.
To learn more about capacitors, check out the Electronics Class. And should you have robots on the brain I have a Robots Class too!
