i have a toy electric motor running of 2AA batteries ,ive comeup with the idea of replacing the batteries with a capacitor charging circuit from a disposable camera ,however the capacitor in the camera board is rated at 330v,180 micro farad.how can i reduce the voltage from the capacitor 330v to3v ,is it possiable to control the rate of discharge of a capacitor so it gradually discharges its power to the motor
