Don't try this at home (Score 1)

The Flyback Transformer project page has some pretty choice quotes. If safety was a factor, then these gems would probably never have been written.

"You will not be able to locate the high voltage return pin with a multimeter. The only way to do it is to bring the high voltage line down to the pins and whichever one it arcs like mad to is the one yer looking for. Try to stay away from arcing to any of the pins used for coils."

"With such small current at this voltage you can even touch the glass with only a tingling sensation to your fingers (no permanent damage) but don't bet your life on it."

"I intend to keep pushing a flyback until the coils melt or it explodes."
