Joule Thief

[Rosphere]

I found this web site today: http://www.talkingelectronics.com/projects/LEDTorchCircuits/LEDTorchCircuits-P1.html
(The page information notes a last modification date of September 07, 2008.)

Here is our friend, the JT circuit, with a different name.

EDIT: (See the note about the added capacitor.)

thank you conrad for all your kind words and drawings .. your so good at them ! 

im happy you have earned great results !

makes me smile !  : )

this is for mk1 the boy who tryed to take what clearly was not his to take ..

regards ... 

look at the date ... 

mk1 were you even a member on this site at that time ...

NO BOY YOU WERE NOT !

ist

it looks like i even had the jt solved when i posted it ...  hummmmmmm

YA THINK OR DO YA ?

IST'S NPN / PNP CURCUIT

time and date fagget !  hummmmm

it dont take huge math skills to see wich came first ... 

REGARDS ..

mk1 regerstration date !

HOW FUNNY IS THAT FAG! : ) im so 3008 your so 2000 late ...

@ist

You are some dumb moron even after Stefan told you many time to be civil , you just can't stop. Showing how much respect you have for people and stupid you can be.

So now Mr Smarty pants , let me show you how easy it is to make you look foolish ... And juvenile .

Now you are right i was not even considering joining this forum at that time and was not even aware that one half god named Ist was living with us mortal ...

That should be enough to shut you down ...  you did not get it yet.

Ok so lets make things clear you are claiming paternity for all circuit using npn pnp  ? It would be hard to do anything else since there is no schematic or any explanation or any circuit what so ever in that tread , now how could someone not that smart like me steal some out of this world tech that you only understand ? Without any knowledge or intent.
That tread is about as relevant as you are .

It not your fault if you did know anything about electronic , you would see how foolish you are.

There is nothing to steal , there is nothing there 

So i was not around you clearly proven it , it also proves i did not steal anything from you ...

Now if you what to talk about my circuits that used NPN and PNP transistor , you can find the first i made with schematic in the (schematic tread) and pictures of the completed working unit .

And i modified it recently and also posted schematic to help others .

Now it is Saturday you know Sunday is a good day to be put on read only.

Its like you want it ?.

Give it a rest .

Kid you should have stayed in school , for basic social training .

Have fun !

No wonder it always sound like you invented everything , did you invent those transistors , humm ok you mean you invented NPN PNP transistors ?

If you did i am so sorry i did not know that.

IST:

Your disrespectful posts have been removed.  Please stop claiming that you invented the JT circuit.  The credit for the circuit and the name "Joule Thief" goes to Big Clive.  (Dating back to 1999) This has been well established on the internet and can be easily researched with some simple searches.  This was done many, many years prior to my starting this topic.

Stefan warned you to only post in topics that you started.  You did not start this one so I have removed your hateful postings.

***EDIT*** 

To set the record straight for the new folks here, this is a video posted on Youtube in 2007 by Evil Mad Scientist Labs on how to make a Joule Thief.  They also credit Big Clive with its invention:

Here is a link to Big Clive's invention:

http://www.emanator.demon.co.uk/bigclive/joule.htm

You can easily see that this dates back to 1999 and was published in a magazine called "Everyday Practical Electronics"  Since magazines take some lead time to be published, I would correctly assume the device was born somewhere prior to the publication date of the magazine.  Big Clive credits  Z. Kaparnik with the original idea for a single transistor circuit.

So, any claims folks might have read here by someone claiming they invented this device 3 years ago are not correct as can easily be seen.

I started this topic in November of 2008 after seeing Bre Petis and Wendal Oskey's video (I posted the link one post up) on how to make a JT, and they were inspired by Big Clive.

Thanks for the link.  It was fun to see a JT small enough to be hidden inside of a tiny incandescent bulb base.

Sorry I missed the 1999 history the first time that it was posted here, somewhere amongst the thousands of replies.  (It's like a hoarder's house in here: every trivial post gets saved and stacked, so we don't lose anything.  But saving everything also makes it impossible to find anything useful.)
