“Can we heat our daughter’s room with it?”, was what my wife asked when I told her I was going to build a Vibrobot. No – sorry. But as I child I loved Legos and electronic kits. Probably because I never had any. But why should that stop me now. So here is a cool project for you. Build a solar powered robot. Ok, so it’s not a “real” thinking robot, but it is self contained and cool none the less. I saw this cool program called Make Magazine on TV and they were putting together these Vibrobots. A company called Solarbotics out of Canada can help with the parts, including the 1381 Symet Solar engine. It has some cool electronics, and reminds me of the movie I saw about the guy who invented intermittent wipers. So the solar cell loads up a capacitor, a diode (1381?) trips and sends the stored electricity to the motor (cell phone vibrator) and then closes back down when voltage drops allowing the capacitor to load up again. It’s a great little novelty as there is not much to it and clearly no battery. Plus it may just sit on the kitchen table for a spell before it decides to move, catching unsuspecting guests off guard.
