Kapanadze and other FE discussion

I did a measurement of the sparkgap firing rate for Ruslan's mini 16W demo setup with the clear top.
It comes out to between 35 Hz to 37 Hz. The small variation may be due at least in part to my measurement error.
The sparkgap firing frequency on this setup is very regular, so it appears to be fired using electronically controlled pulses.

Ive seen some of Ruslans compact grenate devices before they just wind an inner tube resonant with the rest of
the wingdings and simply pulse it at that frequency (electronically). There is a formula for finding the frequency versus wave length chosen and also res freq of wire length it was in a commercially available book. Smith Kelly.

Hmm could that be half of 60Hz and he is using something to double that freq? Gap firing to a coil at around 30Hz, caps on both ends of the coil and you end up with 60Hz?

Better known as Smith Charts. Learn em, use em, they may be difficult at first but when you grasp them, makes calculating values easy. Then tune it.

Hi Belfior. Not sure what the output waveform might look like because he didn't show
any waveforms, and he may not show any more details than that. Ruslan's setup still seems more complicated
than Kapanadze's early demonstrations, so who knows if these Akula/Ruslan type setups might really work at
all the same as Kapanadze's setups. I think we all do have most of the pieces of what makes up these
Akula and Ruslan setups, as Akula and Ruslan did reveal a fair bit. I think they both may have held back on
one or more important details still however, so more experimentation still needed. I could be wrong, but I think
there may possibly be some clues there in all those comments and videos that were made previously.

Waited too long to modify so will add separate. Here is a quote from the search:


Smith chartThe Smith chart, invented by Phillip H. Smith (1905–1987), is a graphical aid or nomogram designed for electrical and electronics engineers specializing in radio frequency (RF) engineering to assist in solving problems with transmission lines and matching circuits.

The last five words, priceless.
