Meanwhile I'm 95 percent finished with a build. I'm experimenting with a different construction technique than I usually use.

That's nice!  Even suitable for high frequency signals. 
Did you cut grooves in that laminate with a milling cutter?

Heh... .No, I used an Xacto miter box and a small hacksaw blade to cut the material. It's ordinary circuit board material. I cut some long skinny strips, then sawed slots thru the copper every 0.1 inch to make isolated segments or pads, then cut two 7-segment and two 4-segment bits from the strips and glued them to the baseboard with superglue to make the chip socket mounts. Then I positioned the "positive supply rail" strip along the top, and added 5 more little individual pads for the junction points. This turns out to be a very easy technique, and as you point out, the 100 percent ground plane and tight layout should help for HF .

...and I was thinking a milling machine or at least a Dremel tool for such precision work.  Nice "hack"saw job, anyway.

OK.... here's something of a teaser. I did get the mosfet to switch.

This might piss you off but I think I heard the Akula persona say that the entire CMOS Hex Inverter chip was disconnected while making this video.

You'd have to get a confirmation from a native Russian speaker, though.

Thanks but it's really not that precise.... pads are different sizes, angles aren't right, edges aren't straight... it looks more precise than it actually is, I guess. Rough and ready...

No, not pissed at all, I expect goalposts to move, designs to be changed, errors in schematics, etc. And I don't expect it to work at all, really, so if it does I'll be really happy and surprised.   
I think that the DC-DC converter chip should light the LEDs at least, whether the output stage is there or not. But it will take me until next week to find out, probably. By then I expect at least two more new and different designs from Akula.

My video showing the effects I found so far is uploading now and should be ready in a few minutes:

I think that the inverter chip is really underdriven and underpowered, so it's behaving strangely.
