A full foot long arc and get to more then 1million volts eventually. I have finally built a REAL Tesla coil that operates via an arc and capacitor combination. Not just a flyback or transformer setup in series. It was not as difficult as I thought it might be, and since my successful Coil Driver circuit was perfected I have been able to run a lot of things.

I also learned a great deal about TV circuits and Flybacks. I have many projects planned, one is to build my own O-scope from scratch. I have done something similar before-back in the mid 1990s I built a "ocilograph" from scratch with a B&W TV but the picture was weak and I never perfected the drivers and amplifiers for it`s deflection coil. I now know how to do so. This is one of my planned projects. I have used many means to drive flyback or LOPT transformers from old TVs to homemade AC ones. Hartley Oscillators to my take on the ZVS as I posted before-and now, my favorite, a flexible synthetic oscillator and mosfet combination. Simply a 555 and power mosfet IRFP260 was my obvious choice for getting the most out of flybacks without burning them out. Thus the Coil Driver 1628 was born, which I will explain later-powers a TV flyback and here thus the Tesla coil circuits. I am sure I am not the first one to ever use a TV flyback to run a 150Kv Tesla coil-however-I have never seen anyone do it on the Internet or anywhere else. I decided to power my coil with a large TV flyback (yes DC due to it`s built in diodes)- as I had no choice. I simply had to- on a very low budget put this coil and two others together with whatever I had laying around. The primary is made of old TV coax, the coil itself wound around an old plastic bottle. I built the adjustable arc chamber inside a pill container which surprised the very loud sounds...
