Below are some photos of my (finally!) finished ZM1000(R) Nixie tube clock. I am pretty pleased with the end result. The two anodized aluminum plates protect the user from touching the bare board and also look great. It is a compact desk clock, measuring (W×D×H)
100mm×60mm×59.5mm. The digits are
14mm tall, so the time is easily readable even across a medium-sized room. What makes it really attractive however are the ZM1000 Nixie tubes with their very fine hexagonal anode grid. I will solder and assemble a few more of these in the near future, so I also composed a
short manual for the future owner(s). Now available on
Etsy (and perhaps
eBay).
Features and tech. specs:
- power: 9VDC 500mA, standard 5.5mm/2.1mm circular connector,
- timekeeping accuracy: better than 10ppm at room temperature (that's an error of less than 25 seconds per month),
- timekeeping on power loss: min. 3 months,
- selectable 12/24-hour time format, selectable MM.DD or DD.MM date format
- gently crossfading digits on each display change,
- brightness of Nixie tubes is adjustable in 16 levels (for lower 8 levels digits do not crossfade),
- tubes are seated on their original sockets (which have a very firm hold) and are user-replaceable,
- black/amber red or silver/clear color combination.
