Электролиз начинается
при 1,7 вольта
и силы тока 1,6 А
что равно 2,72 ватт

 Thanks Sergei.  I'm going to have to try this.

With a double  resonance coils from your secondary, you could drive a HH0 cell just like Daniel Dingle. Adjust the spark gap to tune the frequency going into the cell.

Hi Sergdo

Thank's very much for your input. :)

I tried a replication and it seems to work very fine

bravo and i will follow your progress

good luck and Spassiba

Woopy, congratulations on your replication.
 
@ Sergei, I was looking at your schematic - I don't read Russian, but it seems that the lower 2 coils on the toroid are counter clockwise in the diagram, and the 2 top coils are clockwise. Is the direction of windings important?

Thanks for bumping this thread Laurent and your replication vid. Sergei's latest vid with a is also very interesting.

It's really a joule thief :) Not having the coils interleaved doesn't really matter.  The two pickup coils end up having a priority I noticed; partially because it's a unipolar oscillator I think, if they're not connected, one will get power before the other, and probably (only hypothetical...) One would get a larger spike in voltage and overall will be a more gradual decay on the induced voltage, than if they were interleaved biflilar.  not trying to rain on the parade :)

Haven't seen anyone melt steel yet with a joule thief :)

Hi Jim

super, it seems to work with not so much turns and one single transistor at 9 volts :o

did you count the turns of the secondary on your toroid ? and what is your variable resistor value ?

well done and now lets try to melt steel yeepeee 8)

Hi Laurent,

Thanks for showing the nice replication.  Please tell if the scope shot you show is taken when the output is unloaded or loaded with the LED lamp?  I gues it shows an unloaded output, if yes please check it when loaded, it is important how high the output voltage is.   Your scope shot in the video shows a 350V peak to peak voltage amplitude if I saw it correctly?

I am thinking perhaps a mobile phone charger which can run from 50/60Hz AC input of 90V to 240V could be used here for a possible looping?  Because most present day and small phone chargers have a switch mode power supply and their output is a stabilized DC,  they have a normal half wave or full wave diode rectifier at their mains input so probably the 2.7 kHz output from your setup would not be much problem,  however the 350Vpp would be an overvoltage for them,  so  you could reduce the 2 x 500 turns to say 2 x 300 turns or make a tap on one of the output coils.  Just thinking  lol.
Here is a phone charger possible inside circuit: http://www.onsemi.cn/pub_link/Collateral/DN06009-D.PDF   of course no guarantee you happen to have such but if you have a small plug-in type and its weight is also small then no chance it includes a normal mains transformer which does not likely work at 2-3kHz instead of the 50/60 Hz mains.

Thanks Gyula

Great work guys,
very interesting, full brightness for such little power, if you have a small solar cell try feeding the light back into the circuit and see how close you get to self-sustaining, the first time this was tried on this forum was a few years ago on the Joule thief thread, But they never seem to be able to get their LEDs to  full brightness.
Good luck

Hi Jim, 

Very good and please try to estimate output-input power relation when you have some time.

Hi Gyula

yes the trace you see on my first video is the trace on load at about 3.36 volt input, and is positive about 200 volt and negative 150 volt so peak to peak 350 volt. I don't know why there is not the same up and down, Perhaps because one coil is 6.2 ohms and the other is 7 ohms. I don't know the inductance because i fried my LCR metter with my other high voltage experiment :-\

Thanks for the idea of looping, it remind me something named Romero. ::)

But Sergdo is right we can melt steel withthis device at about 10 watts :o

good luck at all ;D

Hi Laurent,

I really did not mean to have you some nasty visitors of course I only wish to learn more precisely about the output-input power relation...   8) :D   

Thanks,  Gyula
