Luke,
No dilemma - have your clock and meter too:
1) Keep the beautiful voltmeter exactly as is, with no changes.
2) Turn it into a unique clock by making a little microcontroller-PWM-DAC
project that outputs 00.00 to 23.59 Volts, incrementing each minute as
appropriate.
If you want AM/PM
Don't see that very often.I recognize most of the tubes, but what is the
large end view
at the top right? Another Rodan behemoth?
Hi Nick,
The tube in the top right corner is a jumbo Burroughs B-7011. See catalog
918A for specs.

This is likely JJY and not WWVB.
Japanese radio controlled clocks receive JJY at 40/60 kHz. US clocks receive
WWVB at 60 kHz; and the data formats are incompatible.

If you think adding a blue LED glow to a nixie tube is cool, apparently this is
how real men do it:

About those CD47 tubes on eBay... To me, they look slightly used, or maybe
abused during shipping or storage. You can see minor chipping all along the
expansion slots of the base.
By contrast, here's what the base of a new CD47 looks like:

I agree. It's hard to get faithful photos of the CD47. Maybe because it's large
and thus more 3D than most Nixie tubes.
In person they do not look weird at all. The digits are very well shaped; a
unique and attractive "font". They are gorgeous and gigantic.

cheap, one would simply create a large table of all FLW, each word using
4 bytes. It would be so simple.
But instead he resorted to bit tricks. For
