This is an easy to make project for a High voltage power source. "HIGH VOLTAGE GUNS, MORE DEAD PEOPLE AND MORE HIGH VOLTAGE FUN" Make sure to check out the instructions. Be careful while handling high voltages, this has enough energy to stop someones heart. WARNING: I AM NOT RESPONSIBLE FOR ANY INJURIES OF ANY KIND. PLEASE DO NOT HANDLE HIGH VOLTAGES WITHOUT KNOWLEDGE. IF YOU HANDLE HIGH VOLTAGE WITH NO EXPERIENCE, DEATH MAY OCCUR. IF YOU EXPERIENCE DEATH, PLEASE CONTACT YOU DOCTOR IMMEDIATELY. If you have any problems let me know in the comments, I worked hard to make sure it worked before I published. FAQ 1.Q: My flyback gave me arcs but then it stopped working! A: Try putting in a new 2n3055 Transistor, and put a heatsink if you feel the transistor getting hot. 2.Q: My arcs are tiny! Nothing like in the picture A: This happened to me too, the solution is to switch the leads going to the flyback primary. 3.Q: Im really confused A:If you dont understand how I explained it go to: http://www.instructables.com/id/reupdated-Simple-flyback-driver/?ALLSTEPS 4.Q: I dont have time to find the primary coil A: If you dont want to find the primary coil you can wrap your own around the core on the flyback, this will decrease your arcs though. 5.Q: How many volts should I put in?
