Joule Thief

[jadaro2600]

I think we have a problem then.  Unless we can come up with a way for the magnetic moment to be so minute that it has little effect on the atoms at a quantum level -- ..the alternating current is going to create heat, this is how they heat treat drill bits - through induction heating.  What I think we need is a magentic moment which stays close to the coils.

We're using devices which range in frequency of hertz to megahertz.

Maybe I need to understand why we're using these toroid in the first place.

They have a high Q response; is the closed loop of the toroid responsible for the effects of the Joule Thief?

If this closed circuit is what's key, then perhaps my original coils were the right way to go?  Maybe I just need to concentrate on a fixed design. Or maybe I need to incorporate an additional element to boost the magnetic field when current flows?

edit:
Maybe we need to have a discussion on the most basic principles of how the Joule Thief works.

I can tell you right off that it's a blocking oscillator which uses flyback voltage and a collapsing magnetic field to boost input voltage to higher levels.  This is about all that I know though - I've gone through so many designs, and posted so many circuit diagrams that any one refutes the other or takes it into a different direction all together. _ i'm begining to question the very inner working of such a simple device.

The fact that this device has to be tuned means that we're going to be at the mercy of our toroids and the variances.  If we can compel ourselves to harness the power of the collapsing magnetic field without a ferrite toroid then we may be moving towards something that nearly anyone can replicate with just a few basic parts.  ( moving towards kit status )

 i think the core material is mainly to contain it ... 

HOW EVER       MATERIAL RELEASE TIMES ARE VERRY IMPORTANT ...


YES THIS WILL CAUSE BIG PROBLEMS ... WITH THE FCC

YOU MUST ABIDE WITH IN THERE LIMITS....... 


I HEAR 1 K IS SAFE 

GO BEOND I HEAR YOU MAY GET A VISIT      LOL

TIP

RICHARD WILLIS GAVE ME THIS TIP

THANK YOU RICHARD....   

IF FOR SOME REASON YOU SEE HYDRO GUYS RUNNING AROUND BANGING POLES WITH SLUDGE HAMMERS YOU WILL KNOW ...

THERE LOOKING FOR YOUR INTERFERIENCE RINGS..... 

HENCE THE NEED FOR A SPECTRUM ANYILIZER ... FOR LARGE SCALE BUILDS....

SOMETHING ABOUT INTERFERIENCE AT SOME BIG DISTANCE ...........

I GUESS IT TRANSMITTS....    I GUESS IT RECIEVES AS WELL LOL ...

HUMMMMMM

IST!!

sounds like something i said near the start of this topic .... i was jumped on ... by those that did not understand this .....   

lol

i hope we now have an understanding of this now ... 

i fired back they ALL WALKED ....

by "IF FOR SOME REASON YOU SEE HYDRO GUYS RUNNING AROUND BANGING POLES WITH SLUDGE HAMMERS YOU WILL KNOW ... " what exactly do you mean by hydro guys?

Also, I understand the device may be transmitting a signal of some sort - I've had qualms about this before.  Which is why I haven't bothered puling out this 2 inch toroid I've got sitting over here.  I'm trying to innovate around the toroid ( no pun intended ) but the idea of winding toroids is actually a rather expensive and time consuming one - if a better way can be found around it - while not creating AM transmission to Mars, then as the good captain says " make it so ".

Maybe the JT can be tuned to run at 60hz.

@all

Those that think no one care about what is being done here , just look , what internet is saying , mk1 and ist are wrong.

LoL Thanks google.

The first one attacks credibilty and the other the idea. That is there choice from 300 pages of text , with ist or mk1 mentioned.

i hear china wants this ... 

perhaps there sample is  in the mail .... 

ist!


so it has begun.......
