New to electronics but moderately capable. I am looking for assistance creating a circuit diagram for a pressure plate but with a twist: I need to power a small vibrating disc motor when the circuit is open (i.e., when the force upon the pressure plate is lifted). I presume that a capacitor of some sort will be required and that. Capacitance need only be strong enough to power vibrating motor disc through discharge cycle. When pressure plate circuit is closed, the capacitor needs to charge but without current flowing to disc motor. Possible?
