Re: [TCML] Dimmer switch + flyback?
I've not run a flyback off of a dimmer, but I have run one off of a
relay rig to apply and remove power at about 40-ish Hz (as fast as the
relay could trip.) Results were as Gary mentioned disappointing, you do
get sparks, if you hold the HV lead touching the ground, but they are
about 1mm long, and cannot be stretched. Sorry this won't work, the
frequency is too low. Use a driver like this one on my website.

If you want to vary the power, put a 100 ohm potentiometer between the
transistor base and your voltage divider. There are a ton of other
circuits out there even better than this one (I'm currently working on a
circuit based off of an ARDUINO board, with full duty cycle and
frequency control, much better for plasma stuff, perhaps not the best
for just making sparks or charging capacitors etc.) Try the ZVS for
maximum power, they work really good! Best of luck with your project.

I've used the old dimmer switch/ignition coil trick for a while, and
recently learned you can drive a MOT with a dimmer as well. Is it
possible to drive a TV flyback with a dimmer? Anyone try this?
