Dr bajubjubs asked:


I am new to working with electricity and such and i am grounded so i have a little free time on my hands and i was wondering if someone could give me a fairly detailed description on how how to make a tesla coil, preferably hand held but i don’t really care to much. I have google searched and yahoo searched but everything i get doesn’t really describe how to make it. It would be greatly appreciated. Thanks.

Tyler asked:


Can a normal person build a Tesla coil.Is it really expensive. Can you build a small model of one. If so how?

Coiler B asked:


I built a medium size Tesla coil with a 12,000 volt 60 Ma NST. I get 3 to 4 foot streamers. I want to know the approximate output voltage.

I’m making a tesla “earthquake machine” and I want to know how I can test it once it’s finished. What’s an ideal way to try it out?

matt s asked:


i am building a tesla coil using an mmc tank the my max charge is 17100 volts and the out put from the transformer is 4k volts in an AC curcuit… how does the cap tank charge past 4000? and if it doesn’t on its own how do i make it?

Corbet P asked:


I have seen people draw an arc from a tesla coil to their hand without feeling anything. How do they do this? I have read several different sides of the skin effect and I do not plan on doing this very much but i was just wondering how they do it.
I understand the concept of frequency so please explain the practice of doing it. Where does the ground need to be placed and do i need to be insulated from the ground etc.

worried person asked:


I want to build the simplest one I can, with just a spark gap and capacitor, but I want to make it safe since it is my first time building a tesla coil.

LaX.Pure.ChEVaLier asked:


I just got a mini-lecture from my high-school physics teacher about Tesla Coil and air-cored resonant transformer..but I just can’t understand what he says…I only understand the ordinary step-up or step-down transformer…

so, can anyone make it clear…what’s the difference between a tesla coil and an ordinary transformer?

NB:Do not use “extravagant” or “high-level” words…because my vocabulary is not that good, use “everyday” English if you can…
