Joule Thief

I consider it purely mathematical - the math, which I know nothing about, would simply be based on the currents flowing here or there and not have to take into consideration the ferrite core or it's material properties, etc.

Having said that, i though that I would mention that I made two other toroids in the same way as the one above but smaller and they proved less powerful.

Also, there is, by length, less wire in the outer winding ( current carrying ) than in the inner winding ( voltage collecting ).  Approximately 14 inches and 9 inches respectively.

@mk, i'm not sure what you mean - i've not tried to get it back into resonant mode - it involved a second jtc strung off of the other side of the 4 pin led.

But your mass between the two are awfully close.

Take care.

I see you have 2 jt coils of 26 gauge and a toroid made of copper 30 right? So i see 3 coils here 2 jt and one toroid. You get the picture now?

lol


will it lite a neon close by and charge materails near by !?!?!

or  for some reason does it stay contained ...

my experience copper on copper 90 deg has been not normal 

at 1 point i had electrofied standing waves........     at some distance from the coil.....

hummm

wonder how many of my neibours electronics i blew that day in my hood    lol


i bet there are still wondering how in the hell it is brand new and defective ?!?!?!?!

lol lol

i can hear there wifes now ......   it just worked fine a min ago .....   lol  what did you do SOAPS ARE ON IN 5 MIN LOL

tha poor dude ......  lol


ist!


ooopieeee  lol


needless to say i did no more test after seing this over 1 year ago ....    not like that any way ...  i would not have knowen at all but my father was over that day ....  and he walked through it and got a good zap .... 

this is the only conclusion i can draw     THIS IS BASED UPON AUDIO HENGE TESTS I DID LONG AGO I HAVE DONE THIS WITH AUDIO AS WELL AND MOVER LEAVES ON MY FLOWER PLANT ...  THEY TWITCHED  WHEN I ADJUSTED THE FREQ.... 

I COULD PLAY THAT FOR HOURS BACK AND FORTH ...   MAKEING THE PLANT TWITCH...

@mk,  No, the inner toroid IS a coil used in the circuit, and the one wrapped around it is used to collect voltage; there are only two coils - both are being used.

Check out my Images below, I'll post a schematic of them in a bit - or when DIA decides to cooperate.  The path has been altered in the first one, I use a resistor to turn on the circuit, then remove it after a LED is being lit in its place.. and on the second one, I bridged the { (  bias ) the transistor across the coil  from the } capacitor to the positive terminal of the green LED. ....i tried biasing with and LED but it didn't work.

@all,  It looks like I got the circuit to work with that positive resistance path and without a switch.   

This circuit works with a capacitor ranging from 450 pF to 15 uF or more.  I also got it to strobe for me when I added a tank circuit ( resistor - capacitor ) inline in the positive path.  OR by using a capacitor in place of the resistor bridge in the second image while putting a resistor between positive and the base of the preexisting capacitor ( which need to be a large capacitance for this to work ).
