BUZZ COIL HOW-TO
A few years back, fellow engine enthusiast and friend Jim White threw me a challenge: Could I make a simple, all-electronic buzz coil? I had seen several schematics over the years, but all of them required two or three power transistors, some form of oscillator and an automotive ignition coil. The oscillators are usually the universal 555 timers, which require several resistors and capacitors around them, while the standard car coil is big and heavy. After giving the challenge some thought, it seemed there ought to be a much simpler way.

The modern “single coil per cylinder” scheme used in newer cars uses, as the name implies, a separate
