First off I appologize I've never taken any electronics courses what I do know I've pieced together. I need a control circuit for a 9vdc solenoid that varies the number of "ON" "cycles" per minute. Correct me if I'm wrong but this is called and oscillator yes? I run raw current through a resistor into a capacitor and then into the wiring for the solenoid itself and back to the power source and it should cycle on/off? The ultimate goal is a a micro-stamping system that stamps through the solenoid around 100-200 times a minute on a 9vdc 12000mah rechargeable power source. IF all this is correct so far can any tell me how to find the right resistor/capacitor values for this circuit?
