Joule Thief

@ electricme

You got it. But the black things are my 2 transistors .

The list of movie again. about transformer , transistor , diodes and pull push amplification(it works the same way a jt dose) all really simple and well made.

Thanks all, what a nice bunch.

Good morning all,

@ jesus,
welcome back, it has been a little while since we seen you, like me you have noticed just how fast this thread is moving, very fast inded.
I stay up until midnight some nights, and I comeback next morning and there are 3 or 4 extra pages to catch up on. phew must be powered by HHO

Keep going my friend, let it all sinkin.

Thank you @electricme!

@all
I have a program to convert between the different numbers of a capacitor, I mean pf nf uf etc.
Lets see if the forum accepts it to be posted.

Jesus

Edit:
I could not post it as is I will try on a zip file.

Vile al use hav ben snoozing, I hav ben vorking too much hard.

I hav vinished vindng my torrid wif da secondary vinding. 
my vingers are verting, vay ar trembling viff de efervt, vut vit ist vone.  410 loopies vit von da "vobbin" ass the jaeanna zaid.

I sence da IST is zomvare, is ist looking vor da rezolts, later ist, all in good time.
den I vill pooost dem vor every von to ceee.


Haaaa ha, ha, my tablites-o have vorn avay, ist time foo get serious again.

I made this for you , so this is my single jt with pickup coil , it is in the blue box and each ends is to be connected to the diode bridge(after that you can experiment charging big caps or lighting many led lights.

In the red box is the regular led circuit but it has 2 led and it is the part that we should try to reuse to make initial pulse, but since it is high in voltage it is hard to feed back without effecting the current at the resistor that needs to be stable because it will change the freq .

So that is when i decided to but 2 of those on on toroid, to bounce energy from one side to the other.

***REAL IMPORTANT ***   The number of turns on the coil work on a ratio factor at the same size. 1volt 4 turns IN = 5volt 20 turns Out .

But since there are 2 wire on the joule thief by making it the same amount you just double the voltage , So the initial potential is not 1.5v but the double 3v.

Sorry i try my best to be clear and simple in my explanation but i am a pour Frenchman,lol

But some german?  Electricme you got zapped?
