I will install old kacher secundairy again so to have that part working...... how to deal with the new secundairy.. maybe thicker fishwire?

At what frequency does your kacher secondary resonate.
Have you thought about that.

Tomorrow i continue and will repeate the 1st attempt testing.


Food for thought,. when no options left i consider to make grenade with 1Mhz Fres.

A grenade of 1mhz might be on a low side buddy

All issues wil disapear, ...mayor change is that we dont have a low inductance grenade at 1Mhz.
But was Ruslan's grenade not 240uH?

Yeah! You are right , the less the inductance, the higher the res freq.

Short update results inductor pulsing till now.

Hooked it up as attached   (1st attempt)
Inductor pulsing, see attached schematic Ruslan...with inductor 18.75m(3 layers) pulsing it with 12 to 50V i burned a mosfet protection..

Have you considered at what duty cycle your pp was operating. Your cct. for your pp should have ability to vary duty cycle anyhow. If you give a 40% duty cycle at that volts and considering the numbers of turns you have on yoke as indicated above, you will fry more components.

Conclusion, Ruslan may had some ideas but reality was else. Now how can we make it work?

Rough day apecore.  It happens.

I was looking again at this one:

No ground wire, no Tesla coil; no grenade coil, but it still produces
some power.  A known hoax?  Was Akula's original version also?

I tend to think Akula found something.  And Ruslan followed the
procedure well enough to replicate it.

You throw the switch and jam current into an inductor at the exact
same time you snap a powerful electric field via capacitance into
that same inductor and something happens.  Voltage and current
gets multiplied.  Timing has to be spot on and we have components
that can do it.

I don't know if 250ns is critical or not, but I have to imagine
faster is better which is why larger, more powerful units are more
difficult to get working.  Personally, I am okay with that.  If we
have to scale out instead of scale up, that works too.  Priority
is to get the effect to occur, consistently and under our control.
We get that far and understand what is necessary and what our
boundaries are, then we can tinker with the concept however
much we want.

Some have to believe it before they can see it and others have
to see it before they believe it.  For me, I have to do it before
I can accept it.

Forgot to mention...

On the microcontroller research, I think the little Raspberry Pi Pico
with the RP2040 chip can do what we need.  It has built in
Programmable I/O (PIO) logic that would allow us to stream output
signals at half the system clock frequency which is 133MHz.  So I
think we can squeeze out signal resolution around 15ns.  It has an
onboard crystal oscillator so the signal would be at least as stable
as what is in our oscilloscopes.  Also, this microcontroller seems
to be quite popular at the moment in Europe and should be
available worldwide.  Plus it's fairly inexpensive and easy to use
for this task or any other you might dedicate it to later on.

Everything runs at 2Mhz the moment... Fres kacher and grenade
