now im pulling these figures out of my ass cuse im not home right now but i assume a 1.5v AA battery will provide around 300MaH?the motor is from a mini servo from my old r/c plane. and the small current really gets it spinning with some gusto. if you are familiar with model airplane tech, the reciever and servo systems operate on 4.8 volts. the servos themselves run at about 3v but can still be used at as low as 2v. however i did try the setup with 3v still to no avail. if i remember right the photocell is at 1-2 kohms in light and like 200-300kohms in dark. the trans has a beta factor of 50(?) i failed to cehck the voltage with it connected. sorry. meter is old and analog and i should have exhausted all options before posting but i really appreciate you guys helping me.
