This is Dr. Stiffler's SEC Exciter running a pulse motor wirelessly. An AV pulg is used as well as an Earth ground to gather energy into a capacitor that then feeds the pulse powered spinning top. The energy is gathered around a remote " tower" that is also driving 27 LEDs in series off the one wire feed from the main Exciter. The main unit is running on 12 volts but the amp draw is unknown. The small transistor in the main unit is slightly warm to the touch. The spinning top requires 10 mA and at least .5 volts to operate. The diodes in the AV plug are 1N914s and the capacitor is a 2200uf 50 volt. All of the LED are 3 volt.
