If you ever find yourself with a pile of wire and big transformers and can work with tools without killing yourself you might want to build a Tesla coil. What a Tesla coil does is transform low voltage low frequency (120V / 60 Hz) power into high voltage high frequency (5-1000 KV / 10-2000 KHz) power. It’s done by finely tuned coils and capacitors that resonate at the greatest efficiency. The results can be quite spectacular. The image I used for this entry is of a Tesla coil I shot a few years ago. It was pounding out a million volts of electricity and producing a dazzling display of sparks. The coil was about three feet high and the breeze made by the charge was downright amazing.
