Initially, I want something that can be synchronized to an external source: essentially to replace a rotary gapSomewhere I have the schematic of a free-running driver I made for what I think is the same coil. Can put out 3"+ sparks when potted in oil. Are you interested in that? If so I'll TRY to find it but no guarantee.
How fast do you plan to trigger?
120 hz to start.. then potentially up to 400 Hz or so, in a DC coil.I've got some older designs using things like 2N3055 inverters to make 300-400V and a SCR for triggering (the old Delta Mark V CDI, for instance). And I've got the old Motorola electronic ignition IC and some of the avalanche transistors it was designed for that I got as samples 30 years ago.
But I want to make something that can be readily duplicated by someone tomorrow with parts available off the shelf.
E.g. arduino generating pulses to a off the shelf ignition module. _______________________________________________ Tesla mailing list Tesla@xxxxxxxxxx http://www.pupman.com/mailman/listinfo/tesla
