Single leg pulsing yoke pushpull and using 28T with parallel cap 470nF....

The bemf puls Looks like 4Mhz half wave it does not matter if inductorcoil is 12.5m or 18.75m long.

Earlier scopeshot was measured @ Drain moefet so that isn' t at inductor coil.
Below picture does , not using yoke. Just highside switching inductor coil with negative supply voltage.

The blue trace is grenade output voltage at load heaterelement 240ohm.

So is there magic?

Very Interesting thread - some great work fellas! 


Briefly - looked at the Ruslan device a while back. Just a quick observation and comment:

- the processor timing is key (as you've already discovered) as is the uP pseudo PLL (tracking);
component values can change (temperature, etc.) and the required system "Q" is quite high;

  - note, there are advantages to using an STM32 ARM series devices since they can perform
timing, pseudo PLL, etc. functions directly from the internal registers (independant of the
other CPU functions); this allows quick, solid performance.

Here's a link to a page with a bit of 'overview' information, if your interested:

That's it - I'll leave you all to it! Good luck!

I did the same test with the other 2.0Mhz grenade which has only 12.5m inductor wirelength.

Here we see a shorter puls going into the grenade.
Pink= inductor
Blue= grenade

I will also do a test with the 9.375m inductor and additional a high inductance grenade also.

Ape, Dog, Nick, Alien, & Max your excellent contributions here are noticed and appreciated. Thank you for taking the time to post what you know, especially these oscilloscope shots.

Apecore, I have the oscilloscope, materials, and desire to build my first Kap-style apparatus. I follow your channel. The past weeks I have been keeping up hourly with your discussion and progress.

Is there anything I can do on my end that can aid with the research and data being presented in this thread?

I am happy to present my own data in this thread of the device I build for further analysis and data points. It seems you are on the cusp of a nice breakthrough of understanding. Do you feel that now is a good time to begin my build, or would it be more worthwhile for all involved if I hold off and wait for another couple weeks to build while you and the team continue progressing your discoveries further?

Any and all suggestions welcome. Wonderful progress, y'all!

Keep up the good work!

Thanks a lot always good to have more people who are actively involved.
As you noticed, I m a bit of track in the normal approach.
So if you want to start building I would advice you to start winding a grenade and kacher.
Build some usable electronic boards... like brovin kacher system,  mosfet puls board etc. In order to tune and or run a system.

Let me know what configuration you' d like to built
