Joule Thief

CROWCLAW   : )

THANK you for shareing your work.... 

: )

and i mean tnat!

theres ebb and flow!

glad to see you have shared  and im glad your around ... even it seams at times im not ...

glad to see the diodes spoke of more ...

the diodes i have dug out last night and continue to do so are special diodes recovered from rf amps some are are switching diodes .. many odd crystal ones ..

well i managed to find a feroite cap core coil ...  and man does it work well  sings lites a 60 led nice n bright ... i just added it into the 3 turn jt and i can pull from its secondary as well still pull from back side ...

it sings lould like koolers scr mot unit!   WHEN I WOBBLE IT ...   you must use batteries or diode portect the pos ...  as i end up getting fly back go back to driveing source .. and source dont like it ...

: )

agin merve same deal as mr mag scratch routine ...  and will  ...  im not gonna go there yet ; )

this is how we all grow ...  i have learned ... far more bout life than i ever have bout electronics ...

but it is those simple little things that many missed that are so important !

william  the NUT ! LOL

@merv.. 

nice setup ...   

i want to talk more bout ac ...  because i have massive spikes from my wobbler ...

BUT IN MY ON PULSE I HAVE 500 PLUS SPIKES ALL ABOVE 0 AND  THE OSCOLATION IS BETWEEN 20 V AND 140V ...  AND IT DOES THIS


J WWWWWWWWWWWWWWWL __________JWWWWWWWWWWWWWWWL__________   

all from wobble tuneing   the w's   well over 500 per on pulse .... 

i will make a video today ...  of it in operation on the scope ...  if i use pnp   i see the same result ... 

i can change the length of the way and the freq of the wobble ... 

to a point where there 1000's of wwwwwwwwwwwwwwww in my pulse ... 

regards!

H

it will run for days ... on 1 recharged aa ...  : )

doing just as i explained ... 

i was thinking of mounting all but the pot to the ring and allow it all TO WOBBLE  ..  cus i want to cut down on transistor engery used ...  so it will run much longer ...  useing the 3055 it will run a few days ... 

spitting 2 freq ... 

but unfortinuatally   i have been unable to pick up my materials ...  : (   o well... 

and merve i like your bucket ring ...  lol 

i may go SPEEKER WIRE ....  CARD BOARD TUBE RING ...  large MASS ....  lower selfinductance ...  this allows

a powerful kick ....  : )

and if i go TESLA PANCAKE ...  self induceing ...  well   : )

peace!

xee#2  and J

a gift for you both ... 

this is the  EX WJ JT ...  LOL 

PRODUCTION MOD El ... 

: )

IT WOBBLES ...   it is a transformer ...  and guess what ...  no round and round the core ....

: )

makes it easy and cheep to make ..

regards!

i will post a pic ... 

all that is required is it to be wound peroperly ... 

when properly tuned ...  I NEED NO MAGNET TO MAKE HER WOBBLE

AND K  YOU GONNA LOVE IT ....  NO HEAD ACHE ....  : )

THE 60 LED ARAAY  .. WAS RIGHT OUT THE PACK  ... UN MODDED ....  : )

ALMOST WALL BRIGHT ....  FROM 1.5 VDC SUPPLY

THE THING IS IT MAKES A CRAP PILE OF NOISE ...  AND IS ANNOYING AS HELL ! : )

SOUNDS LIKE SOMEONE I KNOW WELL LOL

: )

@Xee2, I am glad to hear that the 2 lights will work. This is cool. Thanks and
Thanks wilby for the suggestion.

@crowclaw,
Thank you for sharing this with us. It means a lot.

I am wondering about what probably amounts to terms, and a schematic could clear this up.

These are some of the terms we use after a lot of hashing about.
I admit to forgetting one all the time.

The primary of the joule thief is made up of 2 wires, but really if you get in there with your spatial brain you see that they are a single center tapped wire, but drawn as 2.
Drawn as 2 so we can distinguish between the part that is connected to the base of the transistor and the part connected to the collector.
We have found that often the jt works better if there are few turns on the base and more turns on the collector, in spite of the original set up with even numbers encircling the entire toroid.

The one I keep calling the secondary is the one we decided to call the "pick up". This is because of the confusion with the seemingly 2 wires on the primary.

So, if you would rename or reconfirm the names you have used in your circuit, I will be much obliged.

Thank you,

jeanna

Crowclaw:

Nice device.  Thanks for showing it to us.  It was also good to see the scope shot as well.

Jeanna:

I agree.  Correct me if I am wrong but I think what we sort of agreed on was this:

Base coil
collector coil
pick-up coil

Is this correct?  I think this was Xee2's suggestion and I think it works.  I have been trying to remember to use these terms myself.
