Joule Thief

[xee2]

@ kooler

Thanks for the feed back. I will try to get a circuit working, but it will be a while. I was not able to find a suitable SCR at my local parts store so I will have to order one.

[kooler]

i found the one i using in a old pc power supply  400v 4a (scr)

i need to buy me some diac's so i can speed the pulses up...
the neon is not the way if you want to go faster than 6 hz

i might try to use a diode backwards first to see if it will blow the scr...

its kool to take the big toroid (3'') and put 20-30 turns on it and fire this thur it
you can hear the magnetic flux going ''clack , clack  , ''etc...

oh .. that little transformer pulls 101 ma's

@ All:

This was just posted on Youtube by a guy I subscribe to:

It is a pnp npn joule thief circuit that looks very interesting.

im just ordering materials to build this thing public with builders that want a unit like the thing i have explained

in my serching for materials .. i found the steel case 2n2222a

just wondering who has used them and what the result was ... 

i found them at jameco.com  for 35 cents each .. as well the db107 bridges are 22 cents each

gold mine has the toroides .. 5 FOR 1$

and gadget got the CAPS...  60$ EA

as i understand a regular jt .. will FULLY CHARGE THE 650F ULTRA CAP TO 2.7VDC IN 8 HOURS FROM A AA BATTERY .. AND I WOULD EXPECT THIS TO TAKE PLACE A FEW TIMES B4 THE AA IS DEAD ..

CONFORMATION ON THIS THAT IF YOU DIRRECTLY CONNECTED THE CAP TO A AA IT WOULD SUCK THE POWER OUT OF THE BATTERY IN LESS THAN 1 MIN ..

AND THE AA WOULD BE DEAD AND THE ULTRA CAP NOT EVEN HALF FULL ...

CASE AND POINT A AA DOES NOT HOLD 5400WATTS... 

BUT YET WITH THE USE OF THE JT   YOU CAN FILL IT A FEW TIMES ON THAT AA BATTERY ...

OVERUNITY....   I THINK NOT ...

A HUMAN MISSUNDERSTANDING OF NATURE ... I KNOW SO..

IST!

so im odering materials ... and if i dont see a sign ... and this is quite regular in my life ... 

ill take a picture of it cuz you wont beleave other wize ..

i placed the first order .. i bought some THE PERFECT CHOICE PRE PAID VIAS'S

I OPEN THE FIRST CARD JUST NOW ... TO PURCHISE 500 TOROIDES ... AND THE CODE # ON THE BACK OF THE CARD IS 977 LOL 

GUESS WERE RIGHT ON TIME ... 

THIS IS BY NO MEANS A JOKE !

HOWS THAT FOR MAGIC .... ? !

[innovation_station]

finally got the darn pre pay cards figured out sheesh i feel really dumb .. worse than usual lol

none the less

this is what i have ordered .. and i can sell a few parts to a few that want to build with me the exact same thing .. public ..

500 cores 1"
200 npn 2n2222a
500 db107 bridges
100 1k 1 turn .5 watt pots
4 650 f ultra caps ..  i will be buying more a compleate 12v dc unit will require 6 650f caps or the big model will require 1 650f (input) and 5 1275 f (output) caps

then today i also bought a 12vdc step down adaptor... real cheep one ... i will use this to close the loop and make it self running

YES YOU HERD ME RIGHT ... THIS IS A CLOSED LOOPED RING SELF RUNNING ...



LET A SINGLE CHARGE OF DRIVEING CAP #1 BE FIRST CONSIDERED ... 

so it apears .. that if each cap holds 5400watts x5 there is some power in my unit ... 

that would mean in my output cap bank i will have on reserve 27 000 watts 12vdc ..  as it apears..  and 5400 wats to drive it

the jt serves as a starter for my cap motor it charges  the ultracap on the input side to full charge  that cap then runs eather a bunch of small rings or my larger core ...
