The concept could certainly be adapted for nixie tubes and neon lamps, so it's nixie-related as far as I'm concerned. I'm just blown away by the 3D wiring and no ICs.

Even with a PC board this would still be a big project.

That's some very nice work, and incredibly clean construction. I can't
even begin to imagine how long it must have taken to build this.

I'm quite surprised by the total absence of capacitors though. I assume
it uses a power supply that isn't shown, which should at least have a
filter cap, but this amount of digital logic without any decoupling
capacitors still doesn't seem right to me.

There is another discrete component clock here:

It's a more straightforward design on a PCB, and it uses plenty of
capacitors, mostly for coupling the counting stages. Full schematics
with explanations are available in the assembly manual.


Best Regards,
Arne

What about this full neon - nixie clock ? [ http://wwwhome.cs.utwente.nl/~ptdeboer/ham/neonclock/ ]

KABtronics (http://www.kabtronics.com/), the home site of the transistor clock (http://transistorclock.com/), also sells a nixie-tube version (http://tube-clock.com/).

I've built their perpetual calendar.  That kit was easy to build but tedious, with over 2300 solder connections.

What would you de-couple? There are no IC packages, all the logic is done with transistors and switching diodes. The fastest frequency in the clock is 60 hz or 16.66 ms. The transistors can readily be biased to switch at moderate speeds and small loads, no high current transients need be generated.

It's a thing of beauty indeed.
