      Sorry Steve. I didn't mean to send your thread off on a tangent. Lets keep this about the cars shall we folks. Wonderful work as...

      BTW. I forgot to add that you need to enable one of the two trigger wires permanently (ground it) to enable the circuit.

      For what it's worth. I did some more testing on the module I linked to in post 56 (that Big Clive tested). It has some possibility for...

      Ok. I see the schematic now. (buried pretty deep in that product listing). The circuit is not based on the breakdown of the diode. What...

      Beautiful work Steve. Very cool. But what's that engine I see in the background?

      Roy Scholl sells some silicon wire 0.118" diameter rated for 20Kv. It's made by Wiremax. It's what I use. I think he also has some lower...

      Ok. I'll check out the waveforms again. Wow, that's a pretty nice arrangement you've made there. Not sure I know what a frequency...

      Also. What are the blue devices (and values) you have stacked up in the tube? It wasn't until I zoomed the picture that I realized the...

      Don: The neighbours must love you with that Spark gap transmitter with large antenna wires.:) A couple of questions: I can understand...

      Here's a good video to watch. It explains a lot of things.

      Yes I have. The waveforms are pretty much textbook. You can look it up anywhere. See below. They can vary a lot. But the basics are...

      In my experience most folks having issues with blowing sensors is because of poor wiring practice. There MUST be SEPARATE heavy and...

      Perhaps another difference to consider. And probably another way to state what you have detailed Don:: For a given coil - say a full...

      Sorry a poor explanation but in short you really don't want a free wheeling diode per se. It will dampen the coil output. If you use a...
