Z80 Lasers - Big Zappy!

I built this stunner using a high voltage coil that runs off of a 26650 battery. I used a rectifier diode for the supply to bring the voltage down to help protect the coil from burning up too fast. The LED in the momentary switch burned out likely due to the high voltage passing near it but I'm not positive on that. Copper nails were used as the electrodes.
