ss tesla w/ ignition coil

[xee2]

did you catch the current draw from the 6 volt battery..
that looks like a really good spark for 6 vdc..

The video was with a 0.01 uF capacitor and current was about 800 mA. Since then I have decided that a 0.1 uF capacitor works better. I didn't have a 0.1 when I first put the circuit togather so I used a 0.01 uF.

Performance is really good at 12 volts with the 0.1 uF capacitor. I will need to make a Jocob ladder with longer wires before I can make a video, spark just gets stuck at top of ladder.

Wow!

That is a really big spark you're getting xee2 - I cant get anywhere near that length. Perhaps i'll try and buy one of those 0.01 micF caps and see if it helps. Well done

Thanks for the advice about shocks kooler - i seem to only get mild zaps if i keep one hand in my pocket, so it certainly seems to be an internal capacitor in the flyback. Have fun with your new transformer.

A 0.1 uF capacitor works better than the 0.01 uF.

I returned the ignition coil. I was not able to get good results with it. I think it does not like 5KV input pulses. Ordered some goldmine HV transformers and I am waiting for them to ship.

[kooler]

i wish i had my goldmine stuff.. it took a week for them to confirm my order and now i am waiting another week for ups to get it here..
i wish there was another website that sold kool weird stuff ..cheap like goldmine

ah well still waiting..

Increasing capacitor value really helps performance. This is video of Jacob ladder powered by 4 AA batteries.

you can also get different results by using other diodes..
i use the bat46 alot..
but any schottky diode would probably do the same job..
when i use this circuit with low volts and different transistor, i always use a larger cap

i got my fly back to day .. haven't tried it yet but i was amazed at how small it was.. it is half the size of a regular flyback transformer..
xee2..
thanks for posting the pinout of this flyback.. from goldmine
you the man..

@ kooler

I got my HV transformers today. Wow. They are big. Have you done anything with yours yet?

[kooler]

xee2
i haven't had time to play with the stuff i got..
but i am hoping it will be good for atleast 5kv..
??

@ kooler

The flyback will give 18 KV with 6 volts in at 750 mA.

[kooler]

just made a low voltage setup with the transformer..
since it is 1 volt the diode does nothing.. so i didn't put it in..
this is a regular joule thief setup with a cap across b-e ..
and a mje13007 transistor..
i can imagine what more volts will do on this transformer..

@ kooler

Great news, thanks for the video. The flyback will light a tube from 1.5 volts also. So maybe we can get 18+ KV from the transformers with 6 volts also. The advantage of the tranformer is that it does not have diodes in the output coil so we can get AC out and drive a voltage multiplier if we want to get really high voltage. We can also get a negative HV output.

By the way, the diode does work with a 1.5 volts battery. The voltage coming out of the coil is greater than the battery voltage. Put an LED in place of the diode with a 1.5 volt battery and it will light.

Please make a sketch of the pins/wires you are using on the transformer. That will save me the trouble of finding out how to connect it.

@ kooler

This is what I get for the HV transformer.
