Это были мои попытки сделать устройство на другом принципе, я не смог его пока запустить. Видео удалил чтобы не смущало других.



Благодаря Я останусь с этой схемы тогда. У меня другой вопрос, если вы не возражаете.
На видео, где вы расслабиться катушку, последний слой провода не подключен?
Катушка с медью напоминает мне о Качер вы сделали лет назад?


спасибо

Blue probe appears to be _not connected_ to circuit... but there is something else underneath the probe that IS connected to the circuit. Power?
Maybe it is Ground from Scope Probe?  :-\

Possibly. The scope appears to be set to 1 ms/div horizontally, so the frequency of the sinus isn't the mains line frequency, it does appear to be the stated 270 Hz or so. But the probe tip seems to be disconnected!

It is the ground of the probe. You see him disconnect it later on in the video. The ground on the other probe is not connected!

He also has a lead plugged into the external trigger on the scope.

Only having one scope ground connected doesn't bother me much. Not nearly as much as not having the probe _tip_ connected, but still showing a signal!

Could it be connected to a bare wire coming from the pot core, a wire so thin it doesn't show up well on the image?

Hoppy, this is normal. For low-frequency measurements will be only one connection to ground.

Сейчас я исследую другие сердечники, мне кажется что феррит не идеален для такого устройства.
К сожалению мой генератор не совсем исправен, поэтому я немного мучаюсь при настройке.

Now I'm looking into other cores, I think that the ferrite is not ideal for such a device.
Unfortunately my generator is not quite working properly, so I am suffering a bit when adjusting.

  3v OU Flashlight - remains unclear, why the resonant frequency is 269 - 270 hertz?

Wow! I am suffering as you adjust, too!

A whining signal generator and an oscilloscope! And mostly flat lines on the scope! Nice old-new Russian tech, a round CRT in a square bezel, LOL.

Just for that, now you have to watch this.

Ah hah. Perhaps this means he is injecting a signal from a FG and triggering off that. I suspected this earlier.

But the scopeshot appears to indicate that the trigger channel is Ch2 (Look just below the blue pen pointer in the last scope image up above.)

The trolling and missunderstanding of working principles behind the scenes do not help and only confuse people.. is that what you want? Just think about consequences for a minute.

Wow! Can I have the winding details of your coil.  ;)

They could not be any more confused than they were at the beginning of this saga!

No, what I want is for YOU to think about the consequences and implications of someone -- Akula -- who posts a dozen different designs, all using common components, that all are "working" for HIM but for nobody else .... and whose "workings" can be easily explained by simple fakes.

Don't you think it's rather remarkable that a single small CR2016 cell can keep a bunch of LEDs lit brilliantly for _hours_? Don't you think that it is at least plausible that Akula has concealed a couple of batteries inside his mysterious potentiometer bodies that are soldered into the circuit?

Or don't you like the Hungarian Rhapsody?


Let's see your concerted effort to reproduce one of Akula's designs. Please report your step-by-step progress. Thanks in advance.
