This is my tesla coil, which I have been working on for more than 12 months now. In the past two weeks it has seen vast amounts of improvements, going from 18 inches to 36 inches in one night of work. Currently, I am pumping way to much power into the coil than my sparkgap can handle, and the coil suffers from very below average performance for the input power. I plan on getting a smaller power supply for it, and using the big MOT stack on a new and bigger coil I plan on building. THe goal for this coil is to be able to produce 6 foot arcs to ground. As of yet, I have a long way to go.
