My search engine wont connect with that site it says it's trying to down load malware.

you can get toroids wit hysteresis they are the old type used in computer memory
they would be used in switching memory circuit and i read they can stor magnetic field.

yeah something is wrong with this site.
go back to my previous post and see my attachement.

I think this may be related. I plan to check it , waiting for some MKP capacitors to test.

That circuit is not related to LED flashlight. The original circuit was creating resonance in ferrite and also had static potential taking back to circuit for creating second power input.

For example, akula was explaining how to create ferro-resonance and taking static potential from copper plates on both sides of the coil:
https://www.youtube.com/watch?v=_U4mSUz04cg

And the demo circuit with step-down from potential taken from plates on core mixed with piezoelectric material:
https://www.youtube.com/watch?v=yxYX_ZC1XNo

From the closest near-unity replications you can also check on lasersaber circuit - https://www.youtube.com/watch?v=1RXolkA08uk
http://laserhacker.com/?p=491 (not utilising static potential as a second power source back to circuit)

Cheers!

forest,
Interesting yes and not related to the flash-circuit. In welseys thread there was a similar circuit however there was a periodic short-circuit at peak power of the left coil.I am really curious of what you will come up with, good luck

@T-1000 :
all those endless russian videos do not help here simply because we do not speak your language. It was already much work to go through all the postings of the realstannik-forum via google translator.From what I read today the users are frustrated and beleive that this is no valuable approach.
Besides there is a much more simple LED Flasher based on negistor-circuit.
Edit: we should be correct when we talk about phyhical phaenomena that is:

Akula certainly is not experiencing ferroresonance but rather creating ultrasound by magnetostriction and this can happen at diffreren frequencies.Otherwise he would have killed his small transformer in a few seconds...somthing what happenes mainly in power-networks.
Ferroresonance is clearly defined:
https://www.sciencedirect.com/topics/engineering/ferroresonance
Key points: "approaching the knee of the BH-Curve and the remaining much lower inductance in combination with capacitance (series resonance) -> current spike

As I mentioned before, it was creating vibrations needed for piezoelectricity to work. And it was created by resonant approach while consuming microwatts of power. Then feeding back power in circuit from piezoelectricity is more than enough to loop circuit and light up few LEDs.

May I ask what Q factor of resonant circuit means to you ? Can we have such situation that the input power to the radio transmitter is far less then the radiated power on antenna ? I think this is the key topic for very wide range of OU schematics

I am talking about high Q achieved in the coil. Also to keep low current draw the resonant circuit needs only fraction of power and feeding spikes instead of sinus/50-50% square wave is more than enough. So feeding pulse train with like less than 5% duty cycle signals also helps with low current draw.

And did you ever tried to hammer ferrite with second spike on peak of BEMF pulse?

Void · « **Reply #728 on:** July 09, 2019, 09:21:18 PM »

Actually that second scope shot above from Akula's video where the waveform suddenly changes
into a big spike was due to a defect (bug) in Akula's Atten brand scope. That Atten scope has the
same internal hardware (Atten was just a rebranded scope with Siglent hardware inside) and I
was able to reproduce that exact waveform on my Siglent scope, and I demonstrated that the waveform
the scope showed was actually due to a glitch (bug) in the scope's hardware or software. The waveform shown
in the video was a false waveform due to the bug in the scope's hardware/software. There is a thread here
on this where I posted my own similar scope shots and demonstrated that it was due to a bug in the scope.

Who posted this 3volt flashlight? that doesn't work? I knocked this up on a breadboard most of the resister values are wrong
as the switch circuit wouldn't run the pot cor makes a nice squealing noise but doesn't give a sine or square wave out and the
one half of the 4069 doesn't do anything as the circuit isn't finished if a transistor is put between the smoothed output of the PWM
and the rest of the circuit and timed correctly it might be a different story, see the circuit.

To be honest I don't know why i bother on this tread as it is totally dysfunctional from what it was as many of the design guys have
gone.

T100 Hi
Now that is an interesting idea if your piezo xtal will fit in with the buzzing ferrite
but it would require to have a holding container as some of the older pot cores use to have and a sort of washer around the edges so the center of the piezo can move.

Text from the discussion post of the video.

Assembled this scheme, about 5 years ago. The circuit operates with a very low current.Current not more than 5 mA. The circuit is very important for the length of transformer wires. The optimal length is 12-13 cm, tried with other transistors does not work. Only works with 2Т603А. The scheme gives impulses 85кГц, in fact the author of this show. The led limits the voltage to 2 volts. If you replace the led to a resistor, the voltage can be raised to 3.5 V. the current of more than 5mA to raise is not possible. Many thought over this scheme, the best result from it not to squeeze.

Yeah... These bullshit things "need tuning".

Please translate this.

We'll find a way to this flywheel bullshit if its true what we saw on video.

There has got to be a way to make free energy with a flywheel. The dean drive can produce an invisible force in the vacuum of space, this is insane and absurd but true, there has got to be more secrets to this.

I think the author of the video didn't say the ferrite ring core material also matters, the length of the wires and probably he made the cut.. More I think if he collected a second time using time he wouldn't have come out. A third-party radiation source is impossible because it is impossible to excite a closed core at a distance. Despite the fact that the battery to hide in his scheme nowhere.
