A vibrating robot I made for my little brother's 10th birthday. It has 2 batteries, a led and a vibrating motor from cellphone, all on a 20pin IC stand. The 2 resistors are for decoration and balance. I don't know what else to say about it...
Thx for the comment. I was thinking of making alot of them, but it would eat alot of batteries, and I had only 2 motors and I burned one with bad soldering =(
If I find cheap small solar cells somewhere in croatia I will try to make alot of them, some green and some red
