Jeff Thomas GPS Clock

Jeff Thomas has another great nixie clock for sale on eBay.  It is a $299 GPS 6-digit nixie clock that is encased in a clear arcrylic enclosure.  I have a Nixichron by him and it is easily one of the best designed clocks I own.  After reading the manual, this clock appears to have the same or a very similar setup.  The GPS feature is a very nice touch.  If you have ever had a power outage you will appreciate not having to reset this device.

End View Nixie Clock

This clock is based on a Metric A/S frequency counter and apparently this unit as part of a remote display.  I contacted Mikkel to learn more about the original unit but sadly, I have not been able to find any of these on ebay, surplus sites, etc.  Regardless, I really liked the design and thought it was fitting to add to this site.  I really like his construction and of the home made clocks I've seen, the wiring and PCB on this is probably one of the cleanest.

If you happen to have one of these sitting around, be sure to let me know!

Home Made Nixie Clock


Ever since I purchased my first numitron clock, I've been wanting to build a larger, 6 digit version using end view tubes.  I found the perfect kit by Richard White but the only problem was that I needed an enclosure.  While doing my normal research, I found the perfect host:

Peter J Jensen Nixie Clock

I found this clock while looking for new content and not only is this one of the few clocks with end view IN-12 / ИH-12 nixies, they also have a great domain name.  I am partial to the 6 tube version but he also sells a 4 digit version as well.  I really like the simple design of the clock.  There is something oddly cool about the upside down "2" that is used for the 5 digit in these tubes.  I think this might be the next one to add to my collection!

While you're there, be sure to check out his IN-14 based clocks as well.

Concrete Nixie Clock


The vintage Z560M Nixie tubes, used in former East-Germany in the mid 20th century as numeric displays, were the inspiration for the design of Daniel Kurth's ( Nixie Concrete clock.

The Luxembourgish designer enclosed the shiny orange Nixie tubes in a reinforced rough concrete body which can optionally be wall mounted. The strength of this design lies in the application of 'retro technology' and its interesting combination of components and materials, where one is easily fooled as to what is old and what is new. All electronic components in this fully functioning prototype are assembled by hand.

Unlike other clocks that make use of Nixie tubes, this one does not read like a traditional display. Kurth experienced that clocks - regardless of their aesthetic value - sometimes form a disturbing factor in one's house, since being constantly reminded of the time can be stressful. By rearranging the display, one can enjoy the playful interaction between the 6 different tubes without realizing straight away what time it is. A short focus will however allow you to use it as a 'normal' clock. The time in the picture reads 10:23:54.

Check out the movies to see the full beauty of Nixie tubes.

The nixie concrete clock is a unique fully functioning prototype.
Daniel Kurth is looking for production possibilities.
