Did you get it works in the end?

This circuit working perfect. Substitute the transistor for darlington get about 2kv

I can't get it work with a darlington...

Thanks for your comment. It made my day

Whats a darlington?

WTFCircuit

A darlington is a kind of transistor. In a nutshell it's composed by a transistor which drives another transistor, in general a much more powerful one.

How do i identify one?

WTFCircuit

From the datasheet, just search on google the name of the transistor and download the pdf

Just Darlington? Im running a tip31 c right now. 24 volts dc input. This is best ive found. May the darlington help?

Tip 31 b is good also

The transistor which I found to work better is a bd139. I tried to use a darlington but it didn't worked for me... How much sparks your tesla can make?

The transistor to use change with the coil anyway. For example I made a 5V miniteslacoil with a 2n2222, a slightly bigger one with a bd139 and one even bigger with the tip31c, the medium one works better for me ;-)

About one inch....sorry not god with metric.

U have a tower also? I love this curciut

What voltage r u running with and resistor value ?

WTFCircuit

Mine makes around 1cm, less than half an inch, with a bd139 and a 22k ohm resistor. I run it at 12V. The one with the 2n2222 at 5V don't makes any appreciable arc, but it can light up a cfl up to around 10cm, 4 inches, away.

Nice wtf. I am just trying to push it to the limit. I can get 1 inch feathers. But with that i notice negatives. Im working on distance now. 3 Foot with a 20 watt floresecent tube. About the same.4 inches with cfl.

My secondaries are pretty clean couple knots here and there. And im using bifialer primaries.

I have to use a much powerful power supply because the one I'm using sucks a lot

dracp

Yea same im only capable of about 35 volts dc. Othewise my ampers shoot through the roof

It's a couple of weeks which I didn't use my tesla coil... I'm working on a few different projects for the future ;-)

Nice. I'm always working in my basements lab. I have too many projects going. My wife gives me a hard time lol
