What you'll need:
- a Power MOSFET (I used a K2996 - Datasheet: -link-
) (any MOSFET should work, it doesn't need to be exactly this one)
- a good heatsink, the MOSFET will get hot
- 2x 1kohm resistor (0.25W)
- a Flyback transformer (no feedback winding required)
- wires and a soldering iron, or aligator clips and or a breadboard.
- a power supply or battery (12V DC)
- a healthy mind, we're working with High Voltage here!
Flyback transformers can be found in devices with a CRT screen (Cathode Ray Tube) or on Plasma Globes. They generate high voltage, and release the electrons in a cathode ray tube (your screen) When the electrons land on the Fluorine layer on your screen, it lights up.
MOSFET's can be found in many devices. I found mine in magnetron's and also in LCD screens.
Normal transistors will probably also work, but I havn't tested it yet.
