[Teodor] writes in with a unique Tesla coil he designed and built. Unlike most Tesla coils, [Teodor]’s design is able to run with a fairly low input voltage because it doesn’t use a static spark gap ...

This animated film "Spark In The Firing Line" provides an in-depth look at the ignition system of modern motor vehicles, focusing on the role of spark plugs in igniting fuel within the combustion ...

This ignition coil driver is a HOT one! From my recollection, it delivers a nastier spark than the legendary Ford Model T ignition coil. The circuit uses an inverted 555 oscillator that is coupled to ...

One of the main differences in regular maintenance between a gasoline and a diesel-powered car is replacing the spark plugs. While diesel engines rely on compression to create ignition, and thus ...

"It's not a heap, dad. It's a classic." That's harder to justify when your classic muscle car won't start. Nothing like a high-compression V8 combined with a battery that hasn't seen a charge for a ...

A battery in a traditional car cannot directly create engine spark. It’s only rated at 12 volts, after all, so it needs a little help boosting the signal to the spark plugs. To make that happen, a car ...

Relays are common electromechanical devices in electrical circuits that come in two types: either latched or non-latched. Latched relays retain their last switch position even after complete power ...

The ignition system is one of those entities that is overlooked, taken for granted and passed by until something goes wrong with it. Consequently, many enthusiasts don't fully appreciate the ...

The ignition is easily the most misunderstood system in any car. Most enthusiasts treat ignitions like some sort of weird, black magic/voodoo curse best left alone until it fails. Either that or they ...
