I saw this instructable on how to make a high voltage power supply with a CFL ballast circuit and and a long time after that it hit me, instead of breaking all my parents light bulbs why not use an electronic ballast? So I tried it and I was blown away by the results for, what would normally be a rather large circuit (not the CFL, a circuit with the equivalent power), just a ballast. *sorry about the blurry pictures, I had to turn the flash off on the camera and it messed up the pictures a little. Also I didn't get very many pictures because I had already made it before I got the idea to make an instructable.
NOTE: I see a lot of people burning up their ballasts or getting very poor results. Im not sure why but some ballasts just dont like it and some transformers dont give very impressive sparks. My advice would be to do some quick tests in open air without oil, if it works then set everything up, if not then try different ballasts/transformers. And this will eventually kill your ballast no matter what kind it is, mine lasted for a while though.
-=DANGER HIGH VOLTAGE: do not attempt if you dont have very much experience with high voltage=-
Step 1: Hook Up the Primary
Step 2: Insulate It
Step 3: Try It Out!!!
The first part of the video was when I first made it, as you can see it arced to the next pin and caught on fire, in the second part I was using the oil filled Folgers container.
