ignition coil driver circuit

Unread postAuthor: iPaintball » Fri Apr 13, 2007 7:33 pm

I just finished my new ignition coil driver circuit. The coil is driven by a 555 timer and three 2N3055 NPN switching transistors. It produces a 3/4"-1" costant arc. It is so much fun to mess around with. I hament run it up to full power yet, cause I've only used it with a 12v DC step down transformer.

Okay, sorry, I wasn't thinking right. I used three transistors in parallel because a single 2N3055 transistor can't stand up to the voltage. 2N3055 transistors were the highest rated ones they had at Radioshack. And what do you mean they're free?
