Need help with flyback transformer project.

[juju]

hmmm

what is normally the voltage output of a flyback tranformer?

From what i know (im a fool), a flyback transformer outputs about 15-30KV depending on the flyback transformer.

But I know nothing compared to the other awsome guys here on the forum

...

no doubt... this thing is sorrounded by genius people!

take care with the flyback my friend!

[Xenomorph]

I see now, thanks for clearing that one out!.

The best i have found are big carbon resistors at 2.2Kohms, is that good to go?

It depends on the circuit you are using really.
I have run circuits with a single 2N3055 without any resistors powering a ignition coil. Maybe just give it a try and experiment with it.
That´s how these circuits came about, some guy hooked stuff up and watched what happened

Okay The only problem i have now is really what pin is what.. Im not sure what pin belings to what coil and what polarity they got .. Im going to follow Naudins tutorial once again and we will see..

If we look at the scheme Cody drew for me, at R1 and R2, are they supposed to be ontop of each others? or what does he mean with the arrow?
Thats the only thing i dont understand.

You can educate yourself on this circuit element here : Potentiometer - Wikipedia, the free encyclopedia

Oh, didnt know that thing as a "Potentiometer", i used to call it a wheele
Guess i learnt a new word today.

Edit: The Potentiometer works a bit odd.. if i hook -6volt to one pin of the potentiometer (not the pin in the middle) then all of the pins return around -6 volt even if i turn the wheele, but theres only 1pin (the one in the middle) that actually outputs -6 volt if the wheele is at max..
i noticed this by using a volt meter. This has yet confused the way im going to use the pot..
Cody or Xenomorph if you see this, can you please expain or make a drawing of how i am going to solder the pot..

Im going to bed now, ill hear from you guys tomorrow. Thanks for all the help so far, iv learned lots.

Makke,
Get your multimeter out and play with the pot. Set your meter to do a resistance test, around 1-10 K ohms on the meter setting. Hook one meter lead up to the center terminal of the pot. Hook the other meter lead up to either the right or left terminal of the pot. Turn the "wheele" and observe what happens on your meter. From this little test you should see that you will be using the center terminal and one side, the other side will be left unhooked.

nvisser had a good idea about using the transistor in the monitor, that one should work great. You can just use a car battery for the power supply.

Yeah, i got the idea to test the resistance to yesterday.. Im feeling stupid for asking sucha simple question.

Wow.. I finally made it!, I wasn't expecting this. At first it wasn't doing anything, so i switched position on the primarys polarity positions, and then i heard a *zzrrrrrrrrrrrrrrrrr* i got a bit surprised at first, so i brought the outputs togather and it made a arc!! .

Im so happy right now . Thanks alot guys

Now, once i get bored with the SMALL flyback that i'm currently using, im going to switch to the BIGGER one

Im also going to find a properly power supply, and a new resistor that doesn't overheat.

Special thanks to Xenomorph and Cody that have been helping me ALOT with this. golden stars for you

Edit: When i play with the flyback for a while i can smell something strange, is this anything toxic? :O
I remember hearing something about ozone somewhere..

There is some concern about the toxicity of ozone to the lungs.
But much more important:

DO NOT LOOK INTO THE SPARK FOR LONGER PERIODS OF TIME !!!!!!!!!!!!!

This can permanently damage your eyes !!!!! The spark emission has UV components (just like looking into the sun)

Wear welders glasses if you need to oberserve something for a long time.

Some might say this is overcareful, but it needs to be said for someone who might not know. Then he can decide for himself.

Okay, But the ozone isn't hazardous enough to cause any suvear damages?

And what about that High frequenzy noise im hearing, is this supposed to be there everytime im not shorting the flyback?
Yeah i found out it should.

Try this. It is very simply

Try reading the whole topic and then reconsider if your post was so very smart.
