Yes and three unused CMOS inputs are free floating.  They should be grounded (as shown below) or those three inverters will oscillate spuriously ...but maybe that's the key to OU

hi verpies,

There are 2 copper wires(thick&thin) going into the coil from the right side of circuit where there is transistor.
The transistor is connected to the thicker wire.

I will need to double check if the thin wire is connected to pin 1 or pin 7 of the 8 pin I/C.

It's was late last night i can't continue ......

I will post more updates later today once i'm back from work,need to leave home soon.Thanks goodness it's Friday....

Actually an "unused" CMOS input can be configured to pick up the electric field from, eg, a HV secondary coil, and then the output of the gate can be used in a feedback circuit to make the whole affair seek its natural resonant frequency. I don't know if that's what is happening here,

It is not, because outputs of those inverters (pins 8, 10, 12) are not used.

...but it's a technique used by SSTC builders.

That's a neat application of HiZ inputs.
For a while now, I was musing about using this method in a rationometric configuration, where one E-field sensor is positioned in the middle of the long HV secondary coil of a SSTC and another is positioned at the end of it. 
The ratio between their signals would be maximized when a perfect standing wave is formed in the long HV secondary coil of a SSTC.
This would have the advantage of being more immune to noise as this rationometric E-sensor pair is not sensitive to common mode noise.

To protect the receiver/control circuitry from HV hazard of close proximity to the secondary coil, I was thinking about implementing these localized E-field sensors as neon bulbs attached to ends of a optical fiber (potted in black epoxy of course) since neon bulbs do not require a power supply (unlike CMOS ICs).

Do you think neon bulbs would make localized E-sensors that are fast enough to generate pulse-by-pulse feedback signals?

I was thinking of the Akula diagram that has the 5 "no input" gates and their LEDs outlined in blue.


The NE-2 idea is pretty neat. I don't know if the NE2 plasma glow is fast enough to produce discrete "flashes" at, say, 1 MHz or whatever high speed is necessary for a pulse-by-pulse feedback system, but I can probably find out. Certainly they do light up in response to 4MHz or greater but I don't know if they go "dark" between those fast pulses! They probably do, though.

Looks to me in the last video he is jumpstarting the device by holding some iron or magnet near hex inverter, also in second video he is playing with something near device, looks like a bold?.

In his divice no magnets.
