So cool AG thank you The Avramenco master!

Cleaning out the sock drawer!! ?


Will there be a quiz/ test ?


Re: your new topic from “theOrient “


Have a question on bits and pieces “ferrite “?


But please not in this topic ( just a heads up on the query

Seems like you might be outa Snickers bars ??

2015 circuit from Ruslan.

Hello,


In greyed out text this circuit diagram is claiming to be from Alexey Sergeew (another guy with thousands of miles away from Riga).


What caught my attention there was the second Tesla coil pumping to the ground which was never shown in any of videos. The diagram claims it need to work on slight frequency  difference (20khz higher as example) with 10-20 meters distance of wet Earth between grounding of receiving grenade coil with it's Tesla coil. The difference of frequency between Tesla on grenade is the frequency grenade coil is tuned on LC/wavelength resonances.


Well, as nobody here tried this way only can guess what may happen. Perhaps that is a missing component all the time?


And from claims on Dniester device about secondary Tesla coil in other room this claim on secondary transmitting Tesla coil may be gaining some weight to actually try experiment on?


If anybody will try this approach, good luck with results and please share!

P.S> Akula device in Germany - https://www.youtube.com/watch?v=hIqEHc9_Bwo with receiving circuit which also may appear as secondary Tesla coil with thin wire.



Cheers!

Grandfather Ivan(dedivan) says that energy can be added to the system if found  mode when ferrite will be cooled. This is our source of energy. Dissipated heat of the environment.

Yes, in that circuit diagram the receiving Tesla coil is tied over same output coil and capacitor to the ground. Which is for FM with high frequency carrier wave.
And akula also was tuning his coils to the ground connection frequency - https://www.youtube.com/watch?v=F6heKiZgSrU
In beginning of video showing self-resonant frequency of coil with floating end and ground connection over mains then with 2nd ground connection to water pipe.
Then knowing which frequency is to the ground adjusting whole circuitry to work in resonance with it.



P.S> the alexewsergey diagram above is using https://en.wikipedia.org/wiki/Superheterodyne_receiver method for 20khz frequency "transmitting" (which in reality is a difference between 2 Tesla coils).

Hi T-1000,
Additional findings for 2020 related to Akula circuit as attached.

It is not about the ferrite core resonance frequency.i have used ee cores ,round ferrite cores and tv yoke too
Soon I will update my work.
Still in process of I get results do share it

3 -4 turns resonance capacitor 0.47uf ,0.47uf and 0.33uf series.
And output grenade coil 0.15uf ,0.15uf series
Only 1 wire is taken from grenade to diode bridge and other side of bridge is connected to ground and netrual wire
Store it capacitor.
See the alexy circuit diagram I shared.you can see it
For greater output you need 1 uf to 10uf capacitor .
And in this photo I have posted you have to take the ground wire to centre of coil like
Kapandaz did and see akulas diagram too .it is going through the pipe.So when you are tunning the coil automatically the earth resonance is also.
Ruslan used a ferrite core with led to ground wire to see the resonance of the ground while tunning the led on the ground wire will light. You might have noticed in some videos he used this.and one more thing the direction of gernade coil is not important I think.
Taken to account
