this is my first project. Its very simple, but i'm still trying to learn basic electronics. I figured though, that instead of just lurking on the site here, i'd upload this little guy:) it uses a little motor that i pulled out of a remote control mouse cat toy. and a LR 44 battery. I added a peice of speaker wire, to kind of act like a spring, to keep it from tipping over. It took about an hour and a half to build, including the time i spent pulling the motor out of the cat toy.
