Tried a couple of things today...
-Painted a black stripe on one end of the pipe, glued a piece of foil for a reflector, added a light source and a phototransistor, wrote some code, tried to get rotor to sync up with the software/MOSFETs. The motor didn't work, but the code works, I get a good rpm reading on the LCD.
-Replaced the resistors on the regulators, upped the current limit to about 5 amps. I'm afraid if I go much higher, I'll fry up some wiring.

Any other ideas?
