Joule Thief 101

[resonanceman]

Dear Gary,

The Taiwan LED Manufacturer is improving their LED Hat product shown to use one single battery and prolong the life of that battery many times.

That should not come as a surprise to you or the many long time Joule Thief Researchers.  The surprise is that they use Two Atten Oscilloscopes to hunt for the “right configuration”.  That put them in very solid scientific footing.

There is a very strong possibility of significant Government funding in the near future.  There is talk of giving every US Law Maker and/or every United Nation Representative in New York a “forever lasting” LED Hat. 

Overunity Research will get a boost???  Keep up your excellent work.  Money will seek the experts.  I strongly suggest that you get at least one Oscilloscope with csv file capability or work with someone with such a device.

Divine wine is for all.

I am glad to see that someone from the corporate world is using JT type technology

As far as giving hats at the lawmakers to impress them ......what do you think will impress them more a hat with LEDs that last very a long time or a big fat check from an energy related PAC.
Our elected officials vote according to their PACs all the time......so the checks just keep rolling in.

I will believe the govenment will take free energy serious only when we have a multi billion dollar free energy PAC to buy their loyalty

I do believe that there is free energy in our future........but it will be in spite of our governments not because of them

I have been looking into getting an Ocilloscope from time to time.
The little cheap ones are getting better......but for the things I would want to do I would need one that was fast and could handle high voltage...

I thought I might contribute a 'what not to do' maybe save someone in 101 from having a lot of problems.
I was testing my joule theives with an adjustable DC power supply, something like 0-30V and/or 0-3A...
My first one, I wound on about 8 turns of iron fence wire, ended up using about 24 inches of phone patch wire around that, and before I remembered that this thing was supposed to run off of very small voltage (dead AA batteries < 1.5V) I fed this with like 12V+ and ended up popping a couple transistors (they now read open in all directions ) .  I did get this to work, but it requires like 0.06A 0.6V to minimally light an LED.  I tried all sorts of modifications, smaller turns (1inch inner diameter), more wire at the smallest, so my first was 1x, second 2x and third 4x.  The last worked sort of the best, but then when I went back to my first, it had a better spike earlier on.  (yes this is all subjective, maybe i'll try and edit this later to include some pictures.  I finally stumbled on a ferrite toroid.  Wound aobut 2/3 the length of the wire I had been using on it, and wow did that make a difference.  Could light an LED with 0.00A and 0.3V   Limitations of equipment... but I could like 4 with like 0.02A and 0.6V...
I have a couple 6 meter coils that I put on a iron axel of some sort, and connected the coils in opposing direction just like a JT.... these actually worked pretty well, but required a bit of current to get a good flux exchange.
I did learn intersting things like the more current you put into an Iron toroid, the higher the frequency goes, until a certain point.  With the ferrite, the less current I put in the higher the frequency, so at like ground 0 it's already way ahead of the frequency of the Iron... I think I could turn it down just below it turning off that the frequency would go back up as if on the other side of the low current side of lower frequency.  Defintely bying some real ferrites
Oh the other thing I was trying was seeing what effect magnets had on the core, with Iron there was 0 perceptable effect, on the ferrite, alinging the magnet N/S along the circumferance of the torus was the best performane. (was on a spot the torus that had no windings).  Putting the magnet in various direction in the center of the torus was basically just asking the cirtuit to stop working altogether.  Figured if I had a magnet mounted on the side, good way to adjust the frequency would be to just turn the magnet from aligned along the ring to vertical to the ring (which is basically the same frequency as not having the magnet).  Was playing with variuos configurations with multiple magnets but didn't get anything very useful. 

So what to conclude: don't use stranded iron cores if you want a small, elegant joule theif.  You need higher current to get the same magnetic flux induction, or many more windings.

Also in all my coils I couldn't use a resistor bigger than 33 ohms connecting the control coil to the base... actually I had to short it with a 2Ohm resistor to get it to work, finally removed the resistor altogether.  The base never went to a high enough voltage to trigger with like any resistance there.  (was using a MPSA06, well was using 2n2222's but blew up 2 of them trying to see if more voltage would make it work; [right if all else fails, use a bigger hammer?])  Was still afriad of putting more than 0.5A through it, but tested up to 0.89 a few times (even at the 1.5V limit on the other side)

A person early on in this thread said they had JT's wound on air, copper, everything else and that it was impossible to make one that didn't work; I really beg to differ, I had a horribly hard time making my stranded iron cores work.   And a magnet sticks to it better than to the ferrite core. 

Use ferrite!

I was discussing this with an India Engineer.  The discussion focused on the arrogance of the average American who had been spoiled by their past successes.  The attitude is - “how could an old retiree with limited resources from a backward Country solved the Energy Crisis”?

He came to watch the demonstration with an American.  He did much more reading and tried the Joule Thief building but his American friend laughed at him.

The likely result is that someone from “a backward country” will produce an overunity product and then US will play the catch-up.  It will not take too long.  Some predicted the end of the world would come on December 20, 2012.  It may be the end of the old world that relied on fossil fuel.

The scientific evidence is here and can be repeated even in the most backward countries.  Will integrity or arrogance win???

Will integrety or arrogance win?
easy question........arrogance has won every time so far.

Lets say your backward country inventer came up with a great little free energy machine.
At least one of the arrogant people with more money than brains would offer them a boat load of money for it......if the inventer takes the money his invention is never seen again.......if he does not take the money  they resort to charactor assanation and threats.

There is nothing honorable or just about the people that are controling these situations.
If your inventor tries to make money from his free energy machine he will loose the battle........The cards are stacked against the free energy inventer ........and the dealer knows exactly what cards are on the table.

Use ferrite!

I do not know who said that.......it is true in part.
Air core JTs can work.....but I had problems making big air core JTs.
I see no benifit to a copper core.
Bismuth did not work

Like you I had trouble with Iron core JTs.......whether it was powered a powered iron toroid plain iron or black iron oxide.....I am sure they can be made to work with enough power ........but why bother.

In support of anything working........if you use a base resistor and put a fairly good sized capacitor across the resistor to make a tank circuit even 10 or more ft of twisted pair will work as a JT......just connect the end to the beginning of the other wire and fire it up.
