Re: ignition coils
You can make an even simpler setup by doing away with the relay and
transformer. Use a solid state lamp dimmer switch instead. Just put it in
series with a 1 to 10uF motor start cap and your spark coil and run it
directly from your mains. Adjust the dimmer control for best spark output.
The dimmer switch is based on a semiconductor called a TRIAC, which
provides pulsed current for the spark coil. The motor start cap controls
the power level. A bigger cap = more power. If your spark coil runs too
hot, use a smaller cap.
25 years ago I used a spark coil & dimmer switch power supply to excite my
first small Tesla coil. It worked pretty well.
