Gary you get your bcap ?

Gadget 

Yes I got  them

I have been working on finding better ways to charge them for a few days now

I think i just found it . The BIG 140 MM  is KILLER .. I can hear the LED SING !!!! I cant hear high pitched any more BUT I HEAR THIS ONE SINGING !! wow . Its strong as hell I have burned out 5 transistor sand 4 leds in the last 20 mins on n AA batter . I am now usig a 2n3055 and it sings ! massive MAs / Ill get back with you .Got to play with thisone . ITs a w from mag-inc . I ordered two and they only had One left    Charged me an extra 6 bucks from spain on top of 19 dollars ups for just that one . This thing lights from the little secondary  and between base and collector and between emmiter and collector atthe same time !
Unreal  the leds are full bright and about to blow almost  but what amazingis its lighting from the base to collector  and also the normal emmiter  to collector . unusual and i hear them also that is a first for me .

Um gadget, if you can run a cfl it makes over 450 volts.
When the frequency goes down 2 things happen
1- the volts go up
and
2-  You can hear it!

So, if you don't try a cfl first, you should use 20 leds IN SERIES or you will pop them one at a time!

BRAVO.

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 ? and its the first Jt i heard . My daughter can hear every one i made from clear across the room . She says What is that noise  and finds a tini tiny little toroid  bead and says its loud to her . I can't hear them at all.

This is my 4th version ready for testing

It is  3 of what Jeanna calls  bad blue  toroids .

I am pretty sure that these toroids are designed to be chokes

I have 25 wraps around each  toroid all in the same  direction   

The  idea is to make  a bunch of magnetic flux ......then  catch  as much as possible  with  an external  secondary .   
The  primary is huge ..... so  it  should  have a pretty good voltage from fluback all by itself .
The  secondary  is  used to step  down  the  primary .....

This  design  is intended  as a work around  for  when  really big toroids are not available .
anyone  that has  a big  toroid can make an equivelent  circuit by  winding the biggest   primary they can .......then tuning the secondary to get   just a few   volts .

Ideally  I would  like to have a system  tuned to  2.5 V
