That should be the scheme. The transistor must be NPN to work (It doesn't have to be exactly the one listed, it just has to be NPN). I have used a transformer because my program does not have a coreless coil. The number of coils does not have to be 10. I chose randomly. 3 is enough for the primary winding and about 300 for the secondary.

Width of copper wire
How many turns are there in the coil

what are those green and white things?

omg people, you can NOT make a tesla coil with DC power unless you create an oscillator. You don't create oscillators without feedback system and capacitors. Want a tesla coil? Use AC power. This circuit is a scam. You can NOT induce a voltage is the secondary coil without alternating current on the primary current. That is why all these comments are saying "Why this no work waaah?"

it did not work for some reason that I do not know even thow I have a perfect circuit that worked fine but it has to do with coil, your coil might be in effective. but I made it.

It doesn't works . Pls check my circuit! I m uploading photo

Mine no work either. humf. kinda disappointed, I need it to work for a school project that is due VERY SOON.

I can't get it to work. My Dad switched the 2222A transistor to different transistors, should I make sure I use a 2222A transistor? I can't find one, we have looked all over the place. Should I order one online?

What resistor u have used and can i get a shock if i touch the upper end of copper wire? Moreover is there any damage from the high frequency?

hi I just got to know something ur very very very very sensitive baby????????????????????????????

No u wont get shock..
N the resistance is 22k

oui. there is no damage of high frequency: but it is about current which flows through the tesla

I have tried this exactly according to the video and IT DOES NOT WORK!!!
Tell me what should I do.........
I used
Transistor 2N2222A
Resistance 22k
Battery ? 9v
And i did winding of. 275 turns and 3 turns

Hello friends

I made Tesla coil with a similar manner which works fine but has a small defect.

When I approach a lamp to the coil, the lamp lights but if I leave it there the lighting lasts only for 50 second max and then fades away.

I have to close the circuit for some time and open it again to make it light again.

Can you help me with this problem?

I used a BD135 transistor, 9V battery, 6 turns primary coil, 2000 turns secondary.

Thanks for your help

what is the size of the secondary winding
