    Ideas for a capacitor bank for a tesla coil??

    I've built a few tesla coils before, one solid state coil and one flyback tesla coil, however I'm looking to build a new one. I have (as mentioned in a previous post), a surplus of old tubes. I also found a bunch (20-30) of old vacuum capacitors rated for 20kV, they are the adjustable/tunable...

    Question concerning choice of NST for Spark Gap Tesla Coil

    I have been designing a spark gap tesla coil, so far trying to use what I have to save cost. I currently have a solid-state NST and I have read that they don't perform properly for Tesla coil applications (I imagine sudden current draws create back emf that is bad for the transistors?). I have...

    Solid State Tesla Coil Burning IGBTs

    Hi, I replicated the one tesla circuit for a dual resonant tesla coil, followed all the instructions of how to assemble the circuit and how to wind the coils, when I decided to test it first i connected the input to a 48v 5A transformers to be sure all the connections were right and it turned...

    My first tesla coil build

    I've built my first-ever Tesla coil as a project and documented findings along the way here: https://siliconjunction.wordpress.com/2017/02/20/my-first-tesla-coil-slayer-version/ I'd really appreciate any suggestions on how to improve the circuit or writing Thanks a lot for your time Matt

    Tesla Coil Primary and Seconday

    I must first apologize in the event I am breaking any forum rules with this question. I have been working on a rotary spark gap tesla coil for a few weeks and have stumbled upon the question of: does it matter if the secondary and primary coils are wound in like or opposing directions? By that...
