How do you build a small High voltage high frequency power supply?
I need the plans/general guidance to build a high voltage/high frequency power supply like the one used here http://www.youtube.com/watch?v=hUQReIW8f1Q&feature=plcp . He describes it as "A small ignition-coil, driven by a simple NE555-circuit feeds a 2-stage-multiplier. 12kV out...almost no current, but as you see: Enough to start a fire." Im not sure how to build that.
