I'm getting ready to start experimenting with triggered spark gaps for
a TC - all the timing benefits of a rotary gap, but without spinning
blades of death.
What I'd love to find, and I'm hoping the TCML hive-mind can help, is
an off the shelf "electronic ignition" module - not capacitive
discharge, but something that basically is the "points replacement"
that I can drive with an optical link (for HV isolation).
The idea is to use a 12V battery, an electronic ignition, and a
conventional ignition coil as a robust trigger pulse generator for the
spark gap.
Something fancy like the MSD, which generates multiple sparks, isn't
what I want.. I want just the one pulse into the coil.
Back in the day, there were "points replacement" modules - maybe
something I can order as part of a HEI?
(after all there's the famous GMHEICSLR contest, which used the *coil*
of a HEI as the basis for a tesla coil of sorts)
Cheap is good. The ignition coils are $12 - I'm not wild about
spending $100 on what is basically a HV transistor and some biasing
resistors and capacitors.
(No, I don't want to build one from scratch.. been there, done that)
