I use this circuit for base and make with some modifications.
http://labkit.ru/html/clock?id=479
I replaced PIC to Atmega.
I replaced MBTA42 transistors and 10k resistors to 2 IC KF155ID1.
And some pins directed to control led light.

Nice watch. Do you have pictures of the circuit boards to share with us?

Beautiful work there.

Hi phill,
Have you tried asking Pete Virica (PV electronics guy)?
He's probably most familiar with the intricacies of his design.

Hi guys, im phill, ive just built an IN-14 nixie clock, have tested throughout,
4.7V on low output, 174V on high output, 12V input, everything went well,
tested tubes, all fine, now to main power up and nothing, only 12V input is
reading, there are 3 main diodes, 1 of wich appears to be
Yes. K155ID1 is very large, because DIP-16.
But my chip KF155ID1 is smaller, because SO-16 package.

Thanks for that, Martin,
This graph is really helpful, and is extracted from the Burroughs data:
This is for a different tube, but it does suggest that a current of around
8mA (which is what I am getting) with 170V across the tube is not entirely
unexpected.
I will report back when a few new
Nice work. K155ID1 is a very large chip however.
Check out the microchip hv5523.
Very small high voltage serial to parallel converter (qfn-44 package). 32
high voltage outputs.
You can try making a watch with this, very small using the same drive
technique (shift register)
On Wed, Jan 23,
I built two of Grahame Marsh's scope clocks using a wooden base, as shown
here:
https://www.dropbox.com/sh/rldue6seyzty9ju/AAB8kECNtxuRSKLGU4rF6Pm3a/Photos/MikeM?dl=0_nav_tracking=1
A simple acylic case fits over the base. I used black felt to line the
wooden supports. I didn't need to clamp
Similar to the foam idea, in my clocks I use a 2mm thickness of silicone
between the (cast acrylic) clamp and the neck of the tube. The silicone rubber
should last decades, it is translucent for good looks, and it seems to shield
the heat from getting to the acrylic clamp.
As for ventilation,
You can look at the Burroughs datasheet:
https://frank.pocnet.net/other/Burroughs/B5750B585X.pdf for some details on the
multiplexing of Nixies, there are some notes and also diagrams that explain the
necessary voltages and currents in relation to the multiplexing timing there. I
also know
