Joule Thief

[jeanna]

Hi Mark,

I also want to repeat that the 2 jt wires with only a few turns at 180 are the working joule thief and must be connected so the mag field reverses.

Ist did a beautiful drawing, but this detail is not there. The jt wires appear to be unconnected, where in fact they must be twisted together as in any joule thief.

I realized this detail is rarely mentioned so I wanted to here.

thanks,

When you get voltages like 100v or even 60 v rectified, have you also done other tests beyond the meter, to see how much is available? or what work it does?

I am curious. or is this the staying alive part?

I will look at ist's drawing to be sure this detail is there.

the detail is there .... and  this can be configured many ways   

as in designing  a task for it ...   and then designing the ring acordingly ...

it goes both ways .... they can reverse or they can slam   was it not called bucking config ...   

agin this all depends on the units use...

ist!!


here is simple proof... 

a homopolar generator ...  2 speeker magnets ... and a alum disc...  in a cordless drill ......   spin it ...   with the magnets attracting ...

what is the result?!?!?!    ill tell you ... voltage .1 1.5...pure dc ...  ok now flip the magnets so they oppose each other ... and force them togather now you have a bucking configuration ...  spinn the drill

what is the result?!?!?!?!

ill tell you agin ...  1.5 vdc  3 vdc ..... big amps ..  0 back torque ... 

problem is to take the power off it ...

TESLA SOLVED THIS PROBLEM ..   by sectioning the disk wich actually intrupts the flow and he harnesses the big kick

THANK YOU ....

IST!!

Hi Ist,

I only meant it is not in the drawing.

In the drawing the ends of the 2 little wires are short and facing out and there is no connection shown between them.

I am not finding fault with you, I just wanted to point it out for someone new to the joule thief.

sorry,

no need for sorrys ... 

in the pic i made i show a finished wound pick up coil  showing all ends  at the top this means back wind them but properly ... 

i tryed to indicate this in all my mk2 coils as i used 2 diffrent colored  wires  for each winding

all is good

we will get er done yet 

ist


ill post the 6pac tonight it is almost compleatly finished ... 

ps ....  i did not have to build the sectioned tesla copper disc to understand this simple concept ... 

THIS IS THE TRUE... 

we can pull out the old TESLA BIBLE  if we need more proof 

lol

but people get pissed when i use my RED MARKER  lol

I did something sounding similar to what you describe - them being 180 to one another - I've been calling it a linear transformer because it's just two wires tightly twisted together without a toroid or any core.

@all,  the latest edition of Nuts and Volts as a DC to DC converter which utilizes a a toroid in a similar fashion that the joule thief is built.
