Twin DRSSTC Project

Eric Goodchild and I have built two large twin DRSSTC's. The DRSSTC is a modern type of Tesla Coil that typically uses IGBT's in an "H-Bridge" configuration that switch power into a tank circuit. The H-Bridge is turned on for a few hundred microseconds during each spark event. During this time very large peak currents are created within the tank circuit. (about 1 kiloamp peak for our coils)

Chain Mail Suit Project

Eric and I have constructed a chain mail suit which allows the high voltage electricity to hit our body.

We have begun initial testing on the suit.
