@ kooler

Nice circuit. I am surprised the ignition coil does not short. Do you know what kind of ignition coil it is?

Thank you @kooler! I will try to find that kind of transformer.

the coil is from a dodge ram 1500 5.2 liter

the little ford coil doesn't work as well for voltage but has some current on it like real red spark..

@ kooler

Thanks. I will try to get one. The JT part of your circuit looks brilliant. The diode should get the transistor to turn off fast - thus big voltage spikes. It should work great with a flyback transformer. I will be trying it as soon as I get some parts and some free time.

PS - I hope you are recovering from your fall.

thanks,
my back is healing slowly..
i made a small mistake in the schematic
tinycad did not put a dot on the emitter to negative.. didn't know if many people saw that.. (pese pointed it out.. thanks man)
yea the diode does make the cutoff alot sharper..
the cap on the base just reduces heat and gives a little more power .. you won't need a heat sink on the transistor.. it stays cold..
you can run this on a 9 volt battery.. but i was using a wallwart because 9 volts cost alot..

ps.. this circuit will short out a m.o.t. in the first 5 seconds.. but if you dip it.. you can get alot better sparks than the ign coil..

I got a few tests done. I really like this circuit. It should charge up capacitors really fast.

That was a beautiful blue spark and very solid looking.

@xee2
awesome..
looks like you made a efficient ozone generator..
question here ?? does the transistor need a heat sink on 12 volts..
i haven't had time to play with since last video..

@ kooler

When I drop the resistor to 50 ohms the circuit draws 1.36 amps at 12 volts - and the transistor still does not get hot without a heat sink. Amazing circuit. However, so far I have only run the circuit for a few minutes at a time since I am using batteries and do not want to drain them.

i built this circuit to use higher power input.. and you just comfirmed my goal..
to do it without building heat..
i have a device that i am trying to make a more efficient circuit for and this was the circuit to replace the jt run transformer that blows transistors with heatsinks..
if all goes well you all will see the more simple and efficient device i being working on back before i hurt myself..

excellent work xee2..

@xee2
i fried my ign coils.. very sad day..
so i had to shoot a video of a flyback coil..
what is kool is i have a mot in a bucket of aw32 oil and the sparks off it at 12 volts 940ma's is awesome..
i won't do a video of it..

but heres the flyback

You two are the masters of the high voltage spark!

So sad ....

I made some videos of the Jacob ladder. It work at much lower voltage than any other flyback circuit I have seen. Your circuits are great.

9 volt battery >>> http://www.youtube.com/watch?v=cU0sLf5okZ0

12 volt battery >>> http://www.youtube.com/watch?v=ATsH22ZN0vY

I hope you have a Happy Thanksgiving in spite of it all.

From the 9v video

jesus
thanks for posting the pictures..
it will help anyone who wants to build this..

xee2
nice videos..
i like a one transistors circuits.. (simple) and cheap
