Yes, the first thank's goes to Nekvadrat!
Im curious if we can pump it up at a higher voltage, something like 12v or higher...
A really basic and fun circuit to explore.

My first try was a flop. Did the fix and it runs. Has a very high cycle so both led's are bright. But is an amp eater. Does use a 3055 tho and needs to be changed to a smaller transistor. Proof of concept passed with colors.
Will have a better layout soon as back from 4 day work trip. Will need to figure out how to post pics/vids to show how it looks.
thay
and: tried to run on 3v and will not. Think transistor trigger circuit is too much.

Wistiti sorry I missed details.. I repeated the earth effect, to make sure its repeatable.. and it is! Here is where I connect the earth.
You don't need to remove any LED. And do not reverse the coil.. just use the original circuit on that. The LEDS are both off. But the voltage at battery goes high immediately when I connect the earth there. I got a new video but its nothing different than my last one. Same effect. Strange indeed!
Edit: I think without the Led is working better.

Hey thaelin
I know it's not often easy, maybe just a little phasing error and you'll get it, just keep a small 1.2 volts rechargeable at the start it will be easier.
@ lostfox
wow you discovered a new way with an external mass as indicated, it's good let's keep experimenting.

Hi all.
@Jagau.
I still do not test the circuit, but doing
an analysis by inspection of the same I have
more or less an idea of how it works.
Looking at the oscilloscope image it is evident
What is related to the phenomenon of the curve
negative magnetic permeability of the material
used in conjunction with your way of working.
If you see the video that Zanzal from Avalon uploaded you will see
their similarity.
This weekend I will replicate the circuit without fail,
also that of Loz, to study it better.
Thanks to Nekvadra for sharing.
Thank you all in advance.
YoElMiCrO.

Hi team.
I have restart the experiment cause my transistor fail (cheap one fron Ebay...) I change it for a 2n2222 and rewind on a toroid core.
After a night running on the ultra capacitor, i see a little discharge on the cap. Maybe i have to have a better tuning.
Experimenting will continue...

Hi all
An update
I started this schematic last Thursday 10th with 2.325V and it has been now a week since the circuit works and the voltage is today at 2.54V.
The 2 leds are on and the oscillator is still working.
The nominal voltage of each of the batteries are normally 1.2V, i use 2 of them.
So these are very good results considering that the syteme run 24 hours a day.
Some waveforms taken this morning on the collector of the BT139 is the transistor I use
Take note that on the second photo it is when we stretch the first to see what is inside.

Hi atti
At the beginning the 2 leds flash but when the battery charge becomes stonger,
a little flicker is sent.
did you manage to do it? if so, well done

Only one LED flashes. There will probably be setup issues. It has been operating for three hours without a voltage drop. There is no voltage increase yet. I will perform more tests as my time allows. (my first opinion on the setup: it's like a battery desulfator)
