Kapanadze Cousin - DALLY FREE ENERGY

Just want to clarify something. Any length of wire or coil will have standing waves on it when
fed with a AC signal. This is generally much easier to observe when dealing with frequencies in the high
kilohertz or megahertz. The difference between standing waves on a wire fed at some random frequency
and when it is fed at a frequency that the wire or coil is resonating at is that at resonant frequencies the
current and voltage nodes occur at very specific positions in the wire or coil. For example, at one quarter
wave resonance, one current node occurs at the feed point end of the wire, and one voltage node occurs
at the end of the wire (picture the first quarter of a sinewave). An example of this is a tesla coil running at quarter wave
resonance. The top of the tesla coil will have its voltage node at the top of the tesla coil, and if tuned exactly to one
quarter wave resonance, you will get maximum voltage right at the very top of your tesla coil at that frequency.
So any talk of trying to get a standing wave on the grenade coil doesn't make sense since your grenade coil will always
have standing waves on it at all frequencies applied to it. The only difference in driving at different frequencies is what
sort of specific standing wave pattern will result on your coils. So there is nothing unusual in itself in seeing a standing
wave on your coils, but the exact location of current nodes and voltage nodes varies depending on the frequency you
are operating at.

All the best...

Hoppy, Do I see some metal shielding there or did I have too many pints ?? 

Just apply some logic here. My cellphone's camera doesn't work in distance from 40-50 cm from the coil. Why?  .  Next- Ruslan was always pointing to the " clean" setup. He said if you will have some wires around you get nothing. Why?? Maybe because too much of induced voltage is going to your circuits?  Interference, over voltage... just name it.   Just my flow of thoughts.

  Hoppy:
  I'm using for the grenade former, a 1 1/2 inch pvc sink drain tube pipe (3.81 cm), as was shown by Ruslan.
  Kapandze's blue coil former looks like it may be even smaller than that.
I don't know why people are mentioning 50mm as the right size, as it doesn't appear to correspond to the images seen on the Kapanadze/Akula/Ruslan videos.

  I think that it's possible that I may be blowing my fets when I disconnect the load, while the device is running, or when I start it with no load. As there is over 1000v generated by my device, and the fets can't seam to handle that high a surge, for over a couple of seconds.
  I ordered 10 more IRFP260N from China, which will take a few weeks to get here.

John,

Indeed you do in that particular shot. It looks like the metal base plate that's supplied in some electrical enclosures. However, if you look through his video collection where opened boxes are shown, I can see no other examples of shielded enclosures, so I don't think its that important.

hi John.K1,

I recall Ruslan mentioned somewhere about shielding for the circuit.Yes it looks like a shielding for the circuit.Please don't use cheap ceramics caps for frequency control if you are sticking with TL494 generator.
Try to use mylar polyester which i find produce better frequency stability.Best is still mica.

I will be proceeding with circuit designing at the later stage once nanosecond high voltage produce some effect.Major part of my circuit board will be covered in copper GND(-) as part of design.
