VTTC (Vacuum Tube Tesla Coil)
I’ve wanted for a long time to have a go at building a Vacuum Tube Tesla Coil. With so many choices of vacuum tubes I’m going to start with the relatively common and cheap 811A triode vacuum tube, as far as I’m aware though any transmitting tube with a plate...

Finding the resonant frequency of a Tesla coil secondary
To get the best results from a Tesla coil, the primary and secondary need to be in tune, that is, oscillating at the same frequency. The secondary coil has its own resonant frequency based on its inductance and self-capacitance, and we tune the primary circuit (by adjusting its inductance and...

Tesla Coil Secondary Winding Machine
After winding my first coil by hand with an electric drill I learned a few things: battery powered drills go flat at the worst times, polyurethane enamel is the enemy, and speed control matters.
