what shall I name it?... (please, suggest stuff!)
So far I've only powered this little guy with a flyback supply, set up with a single salt water cap and a simple, single-element gap. At an estimated 8kV firing voltage and a few mA, it produces faint, visible discharges about 3" long. I could run the gap out further, but, so far I haven't had a chance, as it is very loud.
Power: single transistor flyback transformer supply. Estimated 8kV at 3-5mA
Secondary: A 1.25" diameter tube that originally contained candy. Windings 5" long, of #32 magnet wire. Coupling adjustable, as the tube snugly fits into the primary form.
Primary: Up to 8 turns of #22 PVC insulated telephone wire closewound on a plastic film canister
Capacitor: Currently a single salt water capacitor. Will become a single strand MMC.
Spark Gap: the simple, single element static gap, made from a pair of steel angle braces.
I'm trying out a counterpoise ground with this coil, and it seems to work fine. The counterpoise is a 12" circular disc of cardboard, covered with Al foil. The bottom turn of the secondary connects to the foil.
