So I surmise that Itsu's scopeshots are different because none of his channels are inverted

Well, i can "fix" that by swapping the W2 leads over.


Concerning the squeezing i can concure with TK's comments.

Well... the upper left pin of the pin 1 of the mc34063 is where akula's video indicate noise... so I don't see what that would have to do with wither a mosfet or a transistor in the spot that's been swapped...


so what pin 13 of the right side thing is receiving is a sine wave... I think everyone has demonstrated that... but does anything in side 2 really have to be there after pin 13?


right?  that's what I just saw when I rewatched it... and I think that's what you guys have.. pin 1 left, pin 13 of right in yellow and blue?


Edit: Prefix: Meant to say, I think you guys have the driver part of the circuit OK ... right? you're just missing sustenance.

so the sine wave on the yellow is a reflection of the sine wave that's on the blue that doesn't really do anything... there would have to be a diode between the cap and the coil, otherwise the first thing the cap will do is dump back into the coil and never have a chance to power the chip... which is reflected back to the primary and ends up being the real power to the load...

Sigh....

I apologize for having a better screen resolution on my scope.....    :-\

(Note that the frequency of the sinus and bursts is about 300-310 Hz, not the  higher figure given in the "measurement" box.)

hi Tinselkoala,

Long story short -Tinselkoala you have successfully replicated the waveform as revealed by Akula."I can feel you are really close"


After seeing the recent replies from you with Akula screenshot.

It just hit me  "peak burst" isn't as high or higher than the sinewave at pin 1.This is it "the missing ingredient" i have found out why the device you have built wasn't going into overunity(forever) mode. :D
Do observe carefully at the edited Akula screenshot as attached where we can see the burst is higher than the sinewave at pin 1 before diode.
This burst is what making his device run in over-unity mode without needing external power source.

Solution-

At this moment what i can think in order to resolve the issue your having in order to get your "burst peak" higher than sine wave is to do a basic modification to the circuit schematic itself.

My justification in editing this circuit as attached-we know that higher dc source or boosted dc source in this case will produce higher "Bemf"/Burst peak as compared to using the lower voltage source which was in this case 3volt or little less."This is a known fact lower dc voltage source will yield lower bemf even if pulsing at the optimal frequency"

-------------------------------------------

Another /not recommended /crazy/alternative way(But does not give the solution) to get your circuit to go into fake ou mode without battery once oscillation started is to inject BURST signal(With higher peak than sinewave) at the pin 1(MC34063) but triggering signal should only start at the right point in sine-wave.
"This 2nd part maybe a time wasting suggestion"

I also noticed that ... he has the scope ground connected to the board... that means he's grounded too... could be floating power back from there... (more probably if it's a battery powered meter, but grounded none-the-less)

hi itsu,

I can't help noticing your lovely burst peak is higher than sine wave similar to Akula.

Does this results in lowering the over current draw base on your applied solution.

Kindly revert thanks.

and for better clarity... the starts of windings should all be in on the same start of all  windings...




Edit: And; if it's not a PLL, then it's a delay line of some sort.  just 15ns gate delays...(probably shorter with more modern hardware)... could be a pulse shaper maybe.... although I'm curious, I should note again, it doesn't really matter cause it doesn't work... it doesn't do its intended function

Я не думал что столь простое устройство так извратят  :).
В первом видео я говорил про резонанс, и что нужно его поймать, это никто не сделал.

Я продолжаю попытки увеличить мощность в разы, и сделал катушку с выносным конденсатором, для лучшей подстройки, теперь резонанс ловиться очень легко, а амплитуда синуса больше 100 вольт.

Я могу поделиться видео на этапе настройки, вы сами убедитесь что резонанс поймать легко, и не нужно все усложнять. ;)

Частота колебаний очень низкая, слышен за кадром писк трансформатора, обе его половинки в этот момент сильно прижимаются друг к другу. Общее потребление падает в резонансе. Так и должно быть.

На видео я убрал ключ коммутации, он при настройке не нужен, он нужен только для заворота питания.


I did not think that such a simple device so pervert :) .
In the first video I was talking about resonance, and what needs to catch it, that no one did.

I keep trying to increase capacity at times, and made ​​a coil with an external capacitor for better tuning , resonance now caught very easily, and the amplitude of the sine is greater than 100 volts.

I can share video during the setup phase , you'll see that the resonance catch easily, and do not need to complicate things . ;)

The oscillation frequency is very low, audible squeak transformer behind the scenes , the two halves of his at this point strongly pressed against each other . Total consumption falls in resonance . So it should be .

In the video, I removed the key switch , it is not necessary when setting up , he only needed to power inversion .

Ты, яснее и подробнее объясняй, а то многое из того, что ты объясняешь не понятно, а как потом повторить, если не понятно, что ты там объяснил? И чтоб точно знать, что получиться самозапитка, а не паять лишбы паять ,вот если так объяснишь, чтоб повторяемость была стропроцентная, практически, тогда и повторять все захотят, а то ведь ты, к примеру, когда разматывал даже катушки не размотал их медленно, чтоб можно было посчитать витки и посмотреть как ленты те приклеплены медные. Тут даже с теми самими витками может не получиться, а если ещё и витки не те будут, то совсем ничего не получиться, тут не большая мощность, поэтому любое отклонение может привести к неудаче. Сначала пусть получат хоть ту мощность, которую получил, а потом начнут усовершенствовать.

Просьба, у меня нигде нет требования, везде просьбы либо советы.

Ну тогда совет дня - соберите и найдите резонанс.....а потом уже питание заворачивайте.

Как мне заворачивать и искать, если оно не будет работать? Я много времени потратил на это, у меня не заработало. Ещё дальше тратить время не вижу смысла пока не будет ясных пояснений как настраивать и мотать.
