Joule Thief

I tired to reverse the inductor, I also turned it 90 degrees, there was no operational differences, it seems to be decoupled.

Hmmm... Oscillators theoretically require some type of feedback to work. If the inductors are not coupling maybe there is enough ripple on the battery voltage to act as feedback. Very strange.

i have played with the same config.. your last diagram looks interesting.. good work..

if you keep them within 1/2 '' apart or closer they work really good.
if you want a secondary use two inverters link together the same way

these will give you alittle over 200 volts at 1.5 volt input if you tie the two outputs together..
light a noen real bright..

Kooler, I'm not sure which diagram you are referring to.  The independent LRC or the other astable ones.

I toyed with the standard jtc recently and I think the only step I need to take next is adding the trigger coils.  They're small, so the only thing I need to do with them is solder leads onto the ends.

I've read in a few places here about the coil capacitance - can anyone elaborate on this; I was thinking that having a partially bifilar coil ( true bifilar ) with a certain distance of the coil was contra/ counter wound on itself would provide additional capacitance in the coil.

Google "inductor self capacitance"

heres a SMAKER!


i just recharged 4 batterys 2 12vdc deep cycles ! and 2 lawn tractors ..  at 48vdc from a 12vdc 3.6 amp hour battery!  it ran bout 12  hours from that battery .. i started at 38.8vdc  and now its 39.65vdc ...

1 coil

yes its a joule theif JUST AS I SAID IT WAS   

so never mind trying to tell me to post it else where ...

as ill tell you to go post your TPU IN THE TPU SECTION!!!!!

: )

W

i did 12 vdc recharge 24 36 48 and today i will do 60 vdc 1 coil ... 

on this unit i could have 8 feeds all rechargeing 10 batteries each if i so desire !

: )

guess i never learned anything ... lol


thats 80 batteries from 1 : )   and only the back side of the coil no long horn secondaries ...  nothing fancy
... 


NO BAD COILS!    so NO scalar spitting 1/4 meggawatt diode  blowing air coils INVOLVED .... 


: )


i know i got it right years ago!

yea ...  i dont get a head ache eather!

any more BULL FROGS ... want to swim in my pond ?
