Homemade Tesla Coil




About: Nerd Artist Amateur Historian Jeep Cherokee Guy

    I have recently completed and tested a spark gap tesla coil. So I figured I'd post some photos of it on here. I found out about tesla coils a little over a year ago. I was looking on the web and I came across a website that had some kits for sale. I was reading the details and about what they did and was like,"Thats awesome!". So I started reading about them, and decided to try and build one. The first one did not turn out well, neither did  the next few attempts. Eventhough I couldnt get it to work, I kept trying, and finally I built the coil I have now. Its not the most impressive thing you have ever seen, but im pretty proud of it. I've more or less gained the reputation as the crazy experimentor in my industrial electricity class because of experiments an things of this nature. I hope to improve on this one, but I think its pretty cool the way it is. You be the judge, tell me what you think.

    What materials did you use and what is the velocity of electricity it made

    Awesome nice job
    I want help on my tesla coil it is the circuit with which i need help as my driver is a 12v ignition coil all my circuit have failed me pleas help


    I cant see the entire coil, but it seems as though the primary is pretty high up there and spread apart. I think you may get a larger output if you reduced the spacing on the primary winding.

    Out of curiosity, what are the dimensions and whats the estimated frequency its running at? I just built my first mini TC and the reason I ask is because I've noticed that there seems to be a relation to the light emitted by the sparks and the frequency of the coil. Mine is running at roughly 2238.12kHz.

    Great job though, and nice photos

    Glad to see more people interested in Tesla coils on this site!
