Second Stage Joule Thief Circuits

[jeanna]

So Gary,
Will you be connecting the end of one wire with the beginning of the other to make it a JT primary?

I am confused right now, because I do not understand where the secondary will be?
Is the outside secondary going to be sharing a little of the cores of these? I think it must, mustn't it?
It is a similar question I have with my conical wound secondary... or whatever that is.

i say i say .... damm!   NICE UNIT!

WILLIAM

i cant keep up

LOL  let her RIP!

THIS IS TOTALLY AWESOME

ILL tell ya why there no w core 140mm cuz mike bought them all ... i sent him this ring a long time ago to NEW YORK IT IS ALL POSTED IN THE JT THRED!  he still never paid 1 dime for my materials to build it ..  ... and so they steal!!!

so i build it better ... WAY THE HELL BETTER !  : )

If  you go to the Magnetics website and  click on  the  Distributor  Inventory button  ( it is 2 buttons above the order samples button ) 
Then  type  the  number for  your  toroid in  49740 will do
You  will find that  no   distributors in the world  have that toroid in stock .
If  you check the next 5 largest  toriods listed   you  will get similar  results .
The largest toroid  available  through  distributors of Magnetics  is 48613   85.7 MM
Not  small but  not near 140 mm  I do not  remember  the exaact numbers but I think there are a few thousand  in stock around  the world .

This is what  I mean by short supply .

Plus ...... if the powers that be  tried to stop  us ......preventing us from getting large toroids would  be  relatively  easy for them .

gary !!

what a wicket idea!

that looks darn kool   just wild ..  i have to build that!  that is simply too kool

ps this quote goes with my last responce why there no W core 140 mm cores as mike sent me that core to build it on ... cheep guy probally got a sample payed the shipping got the teck for free ... too bad ... i guess he never knew ... reality is i can tune TO ANY CORE... : )

I am sure this one will produce high volts . I have a 6 turn primary and 7 turn secondary . Its lighting up 25 leds in parallel on the secondary and two on the transistor one  BC led  and one CE all at the same time . have you ever seen one light from both  bc and ce full bright from an AA battery ?
