Hi everyone, Jagu
This is what was not clear to me if the winding on Tr2 is also bifilar.
Nowhere did we find out the number of turns. At the beginning it is written on all windings 8 turns and on Tr2 windings with LED 12 turns .. So how is it?
We browsed the internet and saw many pictures of this connection but nowhere is it written koik to turn the threads ..
Thanks again for the provided picture .. I'm going to remake it .. :-)
Hi strape
as you can see in an image already posted on this thtead,
For Tr1 the bifiliar white wire, clockwise you have to adjust for your ferrite, between 6 and 8 turns
for Tr1 the black wire counterclockwise 8 turns
for Tr2 the yellow wire clockwise goes to the LED and has 12 turns.
for Tr2 The green wire has 8 turns counterclockwise.
I hope this will help

Hi all
I built a second device with the same parameters as the first one and instead of AAA batteries I used a capacitor with the same energy in joules as the 2 batteries1.2v 300 ma.
It works, I have the same effect on my oscilloscope, but the capacitor discharge very slowly.
One observation, LED2 does not blink when I connect the capacitor and if I switch the batteries everything goes back to normal. Since a capacitor does not have the same internal resistance and does not charge and discharge in the same way as a battery the impedance Z of the circuit changes in the same way.
I am investigating the process that will allow it to operate with a capacitor.

Hi Jagau how is your setup is still working ? is still keeping the voltage ?i am very curious ,i replicate it and it holds the voltage very long time but is still droping slowly i try diferent ferites and diferent wave forms i have 2 potentiometers one like in setup and one in the base of transistor i try diferent combinations my setup go someware around 300-600 uA consumtion with leds flicering but still not selfcharging i dont know where i am rong. maybe you can help
Mitza
this is my setup is not conected now i play for days but the voltage still drops slowly dont know why .
Mitza
Hi Mitza
The circuit should be built like this:
Why do you have 2 potentiometers? only 1 in the schematic.
Did you forget the loop between the 2 ferrites? look at Yellow trace.
Jagau
Hi Jagau thank you very much for the advice i put the loop also if i connect the loop in a way the consumption go high and if i connect the other way the consumption go down and the wave i am getting is similar to yours i will do it the way you showed me now and i will be back with news thank you again Jagau .
Mitza
i think i found the right pulse Jagau the voltage is rising slowly for now il keep watching for now thanks for the help .
Mitza
Yes well done
you have the right waveform, I can predict a nice trip of more than two months with this setup, well done.
Another great achievement, you are a guy very attentive to details
And if you expand your waveform you should have like the lower one here
thanks for sharing.

In this type of configuration the only problem I could see is the number of charge and discharge cycles of the battery in fact it is the standard life cycle of a rechargeable battery. At a given time and it depends on the age of the battery it is no longer able to recharge itself,
Mine lasted 64 days and I tried to charge them with a standard charger and it had reached their end of life cycle, by placing new batteries the setup is started again and it still works, the ferrite fuel is there for a few things. I am currently working on a version with capacitor, it is not finished.
