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

Background:

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.

Description from Tubeclock.com:

Be mesmerized as you watch the seconds change on this 6 Tube clock.

Fully assembled and ready to use.

Please note that this clock requires U.S./Canada standard wall power (120V AC, 60HZ).
