  • 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.

  • Winding a Tesla Coil Secondary

    This is my first Tesla coil secondary. It will be wound semi-manually to get a sense of the process before attempting to automate future builds.
