Among the few programs i have come across for desgning Tesla Coils This software is by far the best.

Does anyone know of any better ones, or alternate ones I can try.

TCAD and WinTesla are two i use the most as well at MutualCalc which is a great program for calculating the mutual inductance / coupling between two coils.

Hey GODSFUSION, I'm the author of TeslaMap. I'm really glad you like the program, and thanks for recommending it

I hope it can help ya make some nice fat arcs!

I just wanted to mention to everyone else reading this thread that the program is free and available for download at

And if anyone has any ideas to make the program better, just send me an email and I'll try to get it into the next version.

Thanks,
Kevin Wilson

I hadent really attempted any TC's for a few reasons.

1) i wanted to mathmatically design it instead of the triedand true plug and play. The software has really helped me more fully understand whats going on.

2) The wiring to our house is really old and ive blown the ENTIRE fuse panel when i was younger (blamed what i couldent fix on lightening)

If you feel worried about blowing fuses or causing fires then realize, you coil doesn't have to be a amp sucker. Get something simple like a 9kV, 30mA NST. Yhat's only 270W, however, it might consume around 300W. That's only 2.25 - 2.5A (assuming 120VAC Mains), doesn't sound bad does it? Or you can even use a 6kV, 30mA NST. Your wires should be fine, you microwave pulls much more current, heck even your computer too. Plus you can add a 5A fuse for further protection (highly recommended).

I think that Teslamap gives a far too optomistic max spark length in its calculations. I will have to see how correct it is when I rewind my secondary.
Also, it allows you to size your capacitor yourself, this is okay, but I have found that if you go over ~2x Cres you run a great risk of blowing out half of your NST.
Teslamap also sizes your secondary by the 1000 turn limit, which is not true for a solid state TC. I am starting to question the assumption that you should not exceed 1000 turns for a disruptive system (just consider a magnifier which is over 1000 turns!).

I dont have a NST or any money to purchase even a cheap on from ebay. So ive opted out for the MOT design, even thought the current isent really appealing, its all i got.

Thanks but i dont consider a SSTC to be a true TC and see little reason to build one.

How is a SSTC not a true tesla coil?Both SSTC and SGTC are air core resonant transformers. I dont see how replacing the spark gap with silicon means its any less a tesla coil, as both a transistor and spark gap act as a switch.

Umm, so what is it then?
I also find the predictions for resonant frequency to be slightly optimistic in most of the modelling software I have used.

"I think that Teslamap gives a far too optomistic max spark length in its calculations."
TeslaMap gives the theoretical maximum spark length, thats assuming no losses anywhere in the system - of course theres always loses, usually large ones in a TC, expecting to reach this length will only end in disappointment, but if you ever design a 100% efficient coil and reach the max arc length, please let the rest of the world know! So it dosnt mean much, just thought I'd put it in as a very rough guide to arc length.

"Also, it allows you to size your capacitor yourself, this is okay, but I have found that if you go over ~2x Cres you run a great risk of blowing out half of your NST."
Yeah, the program can't stop people from doing stupid things. I'll see about putting a limit of cap size for the "design check" feature.

"Teslamap also sizes your secondary by the 1000 turn limit"
I'm not sure what you mean here - there should be no limit to the number of turns on the secondary. In fact John Freu has been saying for years that about 1200 turns is more efficient.
