KABtronics has a pre-production nixie clock kit for sale. It is still a work in progress but it looks to be nearly complete and a few kits are available for sale. This definitely looks like it would take some time to assemble. It is made of 215 Transistors, 518 Diodes, 472 Resistors and 101 Capacitors. Wow.
Mathew Beall sent in a video of his assemble. Be sure to check it out:
Here is one more creation from the Nocrotec / NixieClocks.de team; this one is a clock based on the beautiful B-5853 tubes. The Burroughs tubes, in my opinion, are the nicest option available for tubes this size. They have a finer wire mesh than their Russian counterparts and the numerals are a little easier to read. This clock, like the IN-8 one, ships with the Black Brilliance case. This clock is only for sale as a kit but it looks pretty simple to assemble.
If someone here buys one, let me know how you like it!
The kit uses Russian IN-8 tubes that have a blue LED underneath to illuminate the glass envelope. This clock has several optional features worth noting: it can use either GPS or a DCF77 receiver to set the time. I have never actually seen a clock offer one or the other so I think that this design is unique in that regards.
The Temp’n’Glow nixie tube thermometer got a bit of an update in the last few days. Claus-Dieter Urbach and Dieter Wächter have just released a nice enclosure for their thermometer kit. The device uses a Dallas DS18S20 sensor on lengths of wire between 1 and 10 meters. It supports up to two sensors so you can use measure both indoor and outdoor temperature at the same time. The update frequency and error detection settings are user adjustable. Lastly, to prevent cathode poisoning, the device cycles though the digits in a slot machine like effect to help lengthen the life of the IN-16s.
