Little guy sensor     Added: Monday, January 19th, 2004     What kind of idea: playful     Related webpage
	I started using copper foil to make my own sensors. Then someone gave us a whole basket of little figures - and I decided to make a sensor with one of the little guys and some copper. I folded a strip of copper under his feet and clipped it to an alligator clip sensor. The other end of the sensor is clipped to a graphite path or drawing. The graphite conducts, so when the guy "walks" on the right place on the graphite, he completes a circuit, and the cricket makes a dancing figure move.
