Please elaborate. What is your power source?
Also, you were wondering about the capacitor: any capacitor will work. In this case, you probably would like a
Electrolytic Capacitor. Make sure the voltage ratings are 3 TIMES the max voltage of the qc. 1000uF - 5000uF should be good enough for a filter cap. Also, don't forget the protection diode. Make sure the diode is set up to only allow current in one direction, to prevent reverse current!
