this is a spirograph ive built lately and i hope to make it better soon but i cant play around with it too much because its for an electronics competition. i used 555 timer circuits to pwm the pc fans which worked pretty well. i got my fs mirror out of a rear projection tv. and my 50mW green laser module is from laselands and my heatsink for it was made by a freind. ------->YouTube - Green laser spirograph
