    How to optimize spark gap Tesla coils?

    My elementary school had its first annual science fair a few weeks ago, so me and my friend signed up and we decided to do it on wireless electricity. So naturally, we built a tesla coil. It took a couple of tries, but we eventually got it to barely illuminate a portion of a fluorescent light...

    Electrical Why isn’t this Tesla coil working?

    Hello all! I have made a Tesla coil using a proven circuit I found online but what I have made isn’t working here is a picture please help. PS: yes I know it is fairly messy but the specs are as fallows: B50k potentiometer One green 5mm led One 200ohm 1/4 W 5% resistor Primary coil is 8...

    Why do Christmas lights glow green near a Tesla coil?

    1. Homework Statement For a high school physics class, I chose to build a tesla coil for a real world application assignment. I was able to build it fairly easily and it turned out great. Before presenting to the class next week, I've been seeing its effect on different types of light bulbs...

    I Discharging argon gas with a homemade tesla coil

    hello guys i made a small crude tesla coil ( slayer exiter ) and i tried it on multiple gas tubes that i had and i have been able to discharge neon , argon but i have a question : how strong the electric field needed to discharge argon gas ?

    I Can i cause NMR with a simple slayer exiter (Tesla coil)?

    hello guys i saw a slayer exciter circuit , witch is the crude more simpler version of the tesla coil and i made it , it works quite well but i have some questions. some questions : 1 - how strong is the magnetic field caused by this tesla coil ? it can ionize neon gas , or argon ? 2 - i...

    What happens if you use Tesla coil to charge a capacitor?

    I am trying to create a high DC voltage output(with extremely low current output). I thought of something like this. The left coil would be the tesla coil. Can I use this to charge the capacitor and create high DC voltage? What would happen if capacitance was really high?

    What exactly does the capacitor do in a Tesla coil?

    In all tutorials I have read on tesla coils, they have said to use a capacitor spark-gap configuration, to create a tank circuit. I want to know exactly what this means, and what is its purpose. I am not going to build a Tesla coil, I am nearly just interested in the science of it.

    Building a musical tesla coil, need help

    What is the general cost for building a tesla coil. I already have a PVC pipe and wiring, but I know I need a board, power supply, coil, led lights, capacitors, resistors, and semi-conductors, etc. I know there are some things I am missing and I am on a budget. If there are any other supplies...

    Will a DC to Pulse Width Modulator work for SS Tesla Coil?

    I am making a small solid state tesla coil. I have the secondary coil, toroid and primary coil but am not sure what to do for a control circuit. I was planning on using two 9 volt batteries for power. Would a DC to Pulse Width Modulator work? This is the one I was thinking of -...

    Tesla Coil Help

    Hello all, I am in the process of building a tesla coil and I need a little help. I have everything completed enough that I can start testing it. I plug the coil in and the spark gap fires immediately and continuously, but no arcs come out the toroid. I tried moving the toroid closer to the...
