This is a fun and useful circuit for demonstrating high frequency high voltge. It can produce up to about 30KV, depending on the transformer used. It is cheap and easy to make, thanks to the standard TV flyback transformer used. It can power LASERS demonstrate St.Elmo’s fire, and even cause a fluorescent bulb to light from as much as 2 feet away
