Joule Thief

[jeanna]

@jim,
You are re-charging a bunch of niCad batteries from the secondaries of a joule thief using 1 battery to run it?

wow. this is sooo cool.

I guess this is possible, because of the diodes?

waydago, cap'n!!!

@jesus,
thank you.

jim you realize that battery is huge....   

lol

so even if you stoped your test now ...  and  mesured the amount used and the amount returned

wich is more or less ....   lol

ist!

have a blast.....    jeanna      ps .. i spelled it right for the first time lol

The new mk1 has 4 pickup coil of 22 turn (2 on each side 22 awg)each giving 72 dc volts.I have not played with anything else for now. Not bad for 88 turns , and 4 turn jt coil at 180.

So, where you had 7 before you have 4 now, Is that what you mean by 4 turn at 180? And do you have 2 of them (at 180 degrees) the way you had 2 of the 7 turns before? or just 1 primary of 4 turns?

and where you had 52 before you now have 88?

What do you see for amps on this?

72 volts. way cool. This is up quite a bit and you went down in the primary at 180 and up in the secondary (if I am understanding you correctly.)

Thanks MK1, you do great things,
Why don't you repost that link to the butler page? It is really interesting and speaks to much of what we are seeing.

@jim, thanks - no bears!

EDIT
thanks ist.

@ IST:

Hey, would you mind to post your modification of the led flashlight again here? (I know Jeanna just mentioned it again and I have been thinking about it)  I have 2 that I can do the same to and I am sure others would like to see it again instead of hunting through all of the past pages.  Thanks.  (That is a great project for anyone to do)

@ MK1:

Great going man!  do you think this is the max for this set-up?  Or, do you think there is more with a few more tweaks?  This is awesome!

@ General Jim:

You do know that if you can charge those huge batteries that you will be making history don't you?  We are not supposed to be able to do stuff like this.  The same goes for Mk1 and Gadgetmall.  Don't you guys know the rules man?
If this could be done, the power company would already be doing it. (Yea right!)

Keep it up all you guys.

Actually i think the fact that a reduced the jt coil from 7 to 4 is the factor that raised the voltage to over 70 volts,
Now i know that the number of turns on the jt are important in not losing energy , You need to find the point where its just enough turns for the toroid, beyond that you louse power on the pickups coils. so 4 time 22 turn ( each 72 volt dc )
Yes 52 to 88 but from 2 x 67 volts to 4 x72 volt, So far i can say neons are no problem i can light has many has i have 3 on 2 coil , sounds familiar but i don't have 30 of them.

I hope its clearer , next positive feedback , change the transistor to 3055 or dual 2n3904, and voltage doubler. So how dose that sound?

180 degrees just to say 2 isolated jt coil , for new comers
