I'd like to cautiously suggest that if there is a
toroid in the converter circuit that it itself might be overunity.

Romero closed the loop & had the device self-running (with runaway) BEFORE Gyula suggested adding the DC converter to stabilise the motor drive

e more question if you are kind to answer: Is the LED on the output or is it on the input-side of the DC2DC converter’s circuit?
Only if the led is on the output side, could you check if it goes on when a small voltage (3V or so shall do it) is applied to the OUTPUT side? (This issue was raised by nul-points).

I really appreciate your prompt help!

Hi Tinu,
Well looking at the board, the led is on the input side.

the led should not be directly on the input or it would fry on 12V input or more. The convertor has at least 2 coils WHICH ARE KNOWN AS ENERGY STORAGE DEVICES. Most of these circtuits also have at least a few caps, which also store energy. Leds consume xtremely small amount of energy...3 seconds of bright led without power for me it says nothing.

@Nali,
so the LED is directly at the input of the DC2DC converter and it has R1 in series with the LED which is
102= 10^2 Ohms= 100 Ohms.

This means it should still light up down to around 1.7 Volts or so.

You said in your test your 10 Ohm resistor smoked and after a few seconds
the 44.000 uF cap was discharged...

Hmm...
now the question is, how much input current the RomeroUK´s Muller motor draws
when the voltage goes down.
As the voltage goes down  , the input current will also fall exponentially.
So also the load  resistance for the DC2DC converter will go up, so he has to supply
less current to the motor when its output voltage falls.

So it is not the constant about 13 Ohms we see which it was at the beginning...
It will go up exponentially.

So maybe this way the 15 Volts charged 47.000 uF cap of RomeroUK´s
device can discharge up to 1.7 Volts level until the LED goes off
and this takes 43 seconds ?
