WARNING: If you decide to build this circuit, take caution as it can create 2000 volts or more, it will burn your skin on contact, and light you up like a christmas tree! Home-made rod winder, winding and insulating the secondary coil against high voltage spark-gap short out. To watch part 2 of 2 the video demonstration of the circuit: http://www.youtube.com/watch?v=3IWrlTSMor0 ALSO: If you use fingernail polish to coat the coils, first use a N-42 magnet on the nail polish bottle to make sure it does not have metal patricles "sparkles" in the polish solution. As this type polish "could" make it easier to cause a dead short.
