Hmm... I also don't see why you do feel the need to type
several posts repeating that you're not going to give any
clear info and that all info was already given in the video...
You would have been much easier off simply stating the
measurement data from the video. After all, it's your video,
you know your own data. Once would have been enough.
But now you chose to post several messages repeating that
you're not going to do that. Which cost you more effort.
Also, why do you feel the need to use such an unfriendly tone?
Nobody here attacked you nor was anyone here unfriendly to you.
A more civil tone would be nice.
Anyway, to get back to your experiment, are you absolutely sure
you're getting constant DC out?
I mean, there is such a thing as the Joule Thief and that simple
little circuit can light a white LED to full brightness from a
"dead" 1,5V source battery. LED won't light when you connect
it normally, way too little voltage and current. But when you
connect it via the JT circuit, it lights up to full brightness.
Even though the battery can never power the LED directly.
Are you very certain that your LEDs aren't lighting up
due to a similar trick?
Main point, in case you missed it, is that lighting a bunch of LEDs
from a source that does not put out enough DC to actually
light them up at all, has been achieved by using Joule Thief
and similar circuits, and that does not mean there is any OU in
those circuits. It's just smart switching.
So assuming that LEDs only light up when the DC output has been
amplified by OU means is not automatically correct: the LEDs may
also light up when a non-OU Joule Thief like trick is used.
With high frequency switching, it seems to me that might still be
a possibility here.
And obviously lighting up 8 LEDs with the input energy that should
only suffice to light up one single LED is 7 LEDs gain.
So yeah, you're getting more light out. Not necessarily more DC,
but more light, yes, I'll believe that.
Don't get me wrong, I'm not saying that it is impossible that you're
actually getting real OU from it, I'm just saying that you don't seem
to have considered the Joule Thief view in your assessment that more
LEDs must mean more DC output.
