Car ignition coils make great spark sources. After all they were designed to power a spark plug. Now, put two of them out of phase and the sparks are doubled in size. Here are some examples.

Don’t put your hand in this one! This uses a disposable camera photoflash running off 3 V using a BD140 and heatsink substituted for the main HV transistor so it can now run at 1.5 A.

This is my earliest use of electronics to drive a solid state Tesla coil using SIDAC’s in place of a spark gap. It is a proof of principle coil rather than a big performer. “Continue reading” for more details and photos. Continue reading
This is a SIDAC IGBT Spark Gap (SISG) module. SIDAC’s are used here as the triggers for IGBT’s to simulate a DC spark gap developed by Terry Fritz here.
