Joule Thief

[PaulLowrance]

After testing the gadgetmall's Joule Thief and his bcap0650, it is my firm opinion that the joule thief is not cop>1. The best I could get out of gadgetmalls was ~ 55% efficiency while charging the bcap0650, and ~ 80% with a fixed resistor as the load. I have on order the exact core gadgetmall uses, and will give it one more try. I've given it a chance, and the recent incident proves to me there's something fishy going on here. Give legit research a chance. Ian & Koen are doing great work on the Crystal batteries. I think Thane Heins is on to something with his bi-toroid designs.

I have better results now.
This time I am using the OW46113TC (not the OJ)

I decided to start low since I thought it might work, and it did.
I have wound this in our method of describing it as:

2T,8T100T
236r
Tip31C

835v
465Hz  -verrry low!!

However, it does light up that 15w growlight tube, and
a 20w cfl

so, it is real and it was easy and stable, so
My vote is
W all the way baby! 

here are 2 pix,

Obviously , you are an expert when it comes to the jt.

Give legit research a chance ?

Well first , the jt is useful , easy to make out of trash , by anyone , ou or not it is useful , like it or not it is as legit as anything on the web .

The jt power source can easily substituted by pretty much anything , since we use 20 mili under 1.5 volts .

The Legit research you claim doesn't even exist , since no OU concept has ever been legitimized in any convincing way , the legit field you are crying for doesn't exist in any way...

We do something useful we should now stop because , we need to dedicate all our time to achieving the OU Status ? Give us a break !

Based on your standard , this complete site is questionable , so what are you still doing here...

@ J   you know it baby!   ;  )  W

so i got sick of ripping crap apart for the metals .. wich are likely worthless...


so i started on the circuits ...

first one i rip apart   irf 740 gold pins ... it thought it looked gold it is the flux !  second irf 840 and mur 860

so i guess i got lots of fets too

nice vides gadget  the 2 torides that get banged 1 is yellow core other green core   both   as i assume  get fired from the colpase of the big cam transformer ... 

as well i found SPECIAL transformers ...  i would say almost THE EXACT SAME AS JEANNAS COIL ...

there 3 pulse coils wired as 1 banger  then a fine green wire .. trigger ....  then 3 output wires ....

looks to be higher current ...  diodes used in this unit mur 460

im removeing the boards ..  then removeing the parts ..

THEN I SHALL RE ARANGE THEM ..

IST

all parts that are contained in thease power supplies ...  WILL BUILD SOME ADVANCED JT/ TPU HYBIRD devices ...

@all

We really need to try Rochelle salt as a core for a jt circuit .
