Here's my setup (for the past couple of months). I have taken several photos as I was adding more LEDs to the circuit tonight just for fun. Remember this is NOT the original setup as per OP but my modified version of the Joule Thief.

I'm adding the photos in sequence, and they are labeled as well, so it should be easy for you to follow. First one is the circuit schematics.

How long your "led circuit" lit on,  for drain that battery with load  one led.

May i know, how many turn bifilar coil to get oscilation between 30 Khz --- 350 Khz.

Nice pictures! 

I will cannibalize a toroid asap.  Nice scope also.   Interesting wave!!!!   I don't see a SINE wave there, I see a sharp gradient! 


@zon

There is probably a formula you can use to get a rough idea of oscillation frequency.  I will post the formula if I can figure it out once I build your circuit.  You can also use a scope or frequency counter to see.  You can get good deals on these equipment on ebay sometimes. 

Thank you for the coil diameter ratio. That is a really good idea.  I purchased the closest ratio I could get (since I am in America all the measurements are different!).

@ Feynman,

thanks, I believe picture is "worth thousand words" and if it helps others, even better :)

@ zon,

I have not really kept the circuit on for extended periods of time, I simply figured based on 12mA of current that it would last days, based on the 2300mAh battery I use. I guess I should do a real test, perhaps tomorrow night I'll keep it on and see what happens.

Below is the photo of the ferrite bead I used and the coil itself. The wire used is 30 AWG bi-filar wound to 20 turns. I might try with AWG 34 and 39 and see what happens, my guess is that the oscillating frequency would change. Right now with this coil you can see it start at 100KHz, but if you add more LEDs the frequency goes down...

@groundloop

On my latest circuit's, after running more than 24 hours

Measurement at the led,  3mA,  2.7 VDC

at (-) battery 1.291 VDC, 13.85 mA

@amigo
I can't  figured how long it will drain, based on cureent at one point, because at certain time it will drain very slow...
It's like ridding bycycle, more power on the start but "less power" after on the road.

@All,

Good morning. My circuit has run through the night. The battery voltage has CLIMED a tiny bit
since yesterday. It is now 0,588 Volt over the battery. I will let the circuit run through the day.
It will be fun to see how long this circuit can run on that single battery before the LED stop lighting.

This is really amazing!

@ All:

One of my Stubblefield earth battery bifilar coils puts out over 30mA by itself, not even in the ground yet, just a little wet.  I'll bet it would replace the AA battery in your circuits.  If I can, I will give it a try.  These are bifilar coils with an iron core and cotton insulation between the iron core, iron wire, and copper wire. (all the wire is bare)  When in the ground they should put out power forever.  This should be interesting.

@groundloop

After you get conclusion on your's circuit, please follow the ratio of bifilar coil. You will see different.

@bill

as my friend said, if we can harmonize/tuned oscilation with earth it will puts out / pull "something". Range of harmonize/tunning area of earth betweeen 30 Khz --- 350 Khz.
Where he get that number, he never told me.

@Bill,

It will be more intresting if this circuit as it is now turns out to be running an "impossible" long
time from a depleted NiMeh battery. The LED is bright enough to actually read a book in total
darkness. (Yes, I have tested that.)

Now a "far out" theory:

The fully depleted NiMeh battery (less than 0,590 Volt) is now performing as a high value capacitor.
Because the circuit loads the battery and the battery can not and will not provide any charge then
the active environment is putting in the energy needed to keep the oscillator going. The battery is just like a spring, we try to stretch that spring even further to get our energy to the circuit, but the battery can not
do that anymore because it is empty, so the energy must be taken from somewhere else. Thus, we have created a negative resistor inside the battery.

(http://www.overunity.com/index.php?action=dlattach;topic=4223.0;attach=20071;image]http://www.overunity.com/index.php?action=dlattach;topic=4223.0;attach=20071)

Another theory is the way this circuit works. The three diodes and the output coil makes a loop of current circulating one way only. The oscillator keeps that loop running at each pulse. Because the speed of the circulating current is very high the extra energy is coupled back to the driving coil and thus charge the battery.

Just some thoughts................

@ Groundloop:

You don't think the same principle would apply when using a Stubblefield bifilar coil in the ground?  I see what you are saying about what you think the "dead" battery is doing and I don't/can't disagree as I am still limited in my knowledge of electronics.  I think it might be possible that the cell in the ground might just have the same reaction as the AA battery.  Maybe not.  So many experiments to do, so little time.

@Bill,

Yes it could be so. I really don't know. I did some experimenting with ground batteries some years ago.
I used Zinc and Copper plates in the ground. I found that the ground battery works but the output was
very low. I did compute that if I wanted any real power (to use a heat, light etc.) then I would have to
make my batteries cover a football field. I do not know if a earth battery is improved by coiling etc.
because I have never tried that.

Anyway, I did measure the frequency of my circuit. I put a pickup antenna close to the circuit and used my spectrum analyzer to see the output. My center freqency is close to 2MHz.

[EDIT] I did measure 62,5 KHz with my scope. So the 2MHz is an over harmonic oscillation.
          I'm sorry for my mistake.

2MHz, What is mean ? I never use the osciloscope and I am still limited in my knowledge of electronics.
I'm just do it with my lovely bread board :)

Is it oscilating frequency... ?

Oops , it's out of area harmonize , 30 Khz --- 350 Khz     

I forget to tell, 1200 mm length of coil , it's not exactly must follow,  i'm just fill the toroid :))
i don't know the formula.

"Joule Thief" makes switch on and off about 50,000 times a second (50Khz). It's within that harmonize area. Maybe they don't know "the harmonize area"

Please find oscilating frequency in that area, 350 Khz is the best efficient

@zon,

It means that the oscillator runs with 2 million pulses each second. Those pulses create radio waves.
Those radio waves can be picked up with an antenna and sown on a frequency spectrum display.
My frequency spectrum display is connect to my computer so that I can "see" all the radio waves
in a graphic chart. The strength of the signal is at left on the graph and the frequency at the bottom.
The stronger the signal the higher up the graphic will go. It is measured in dBm (decibels over Milli Watt).
http://en.wikipedia.org/wiki/DBm

[EDIT] It is the frequency of the oscillator. I'm not sure if your low frequency is better. For the first time in my 5 year long research into free energy (and in my 40 years of playing with electronic) have I seen something that I find amazing! I have never before seen a LED being light up from a "dead" battery. The voltage stays the same and the circuit just keep going and going and going...........  :D

[EDIT] I found that the oscillator runs at 62,5KHz and the 2MHz I saw on my spectrum analyzer was an over harmonic oscillation frequency. I'm sorry for my mistake!

Hi Groundloop,

With highest respect but I cannot help but notice: dBm is decibels over Milli Watt and not volt, ok?  (See your link too.)  When you see using symbol dBu, it surely means decibels over microVolt but here the V symbol is usually omitted just like the W symbol in case of dBm, right?

Respectfully, 
Gyula

@gyulasun,

Yes, you are 100% correct.

[EDIT] Circuit still running.
