I'm trying to make a laser Spirograph. I'm using four 1.5 volt DC motors from RadioShack that will each have a 1" mirror glued to them so the load will be very small. What power supply should I use?
@Laser Spirograph ,
One C or D cell battery. Wire your motors in parallel. If you current draw is small enough, you could drop to AA.

Brains, reading, and work. It will sort out the whole thing for you. Also eat...
@Laser Spirograph ,
The voltage that resembles to the highest motor efficiency. Try to select a main battery pack which is most closely matches to the nominal voltage of your drive motors.
