We have seen lots of interesting projects made for little money using scrap electronics like Microwave Ovens, for this project you will need a piece from another throw away item, a CRT TV. This CRT TV Flyback Transformer High Voltage Power Supply by Robert Gawron is cheap and easy to build since the main part can be found for free in a discarded old TV. It sure makes for a crazy looking jacobs ladder.
“Old CRT monitor or TV is a great source of electronic components that can be used in DYI constructions. One of them is a flyback transformer that can provide 10-30kV output. The input voltage can be in a range from a couple of volts to over a dozen of volts, power consumption is a couple of watts. In my construction input voltage is 9V, power consumption is 5W.”
