TurboHobby just release a new clock single digit vacuum fluorescent clock.  In the near future he will be releasing a kit version of this clock as well.  I'm a big fan of his single digit Nixie clock and I expect this one to be great too.

TurboMac sent in some photos of a Nixie tube dissection he performed on an IN-2 and IN-17. Be sure to note the number of 0's.  Click on the image to load the gallery.

(Thanks for sending these in!)

Talk user John (greyfox) sent in a nice enclosure that he built for his single digit Nixie clock from Turbo_Hobby.  Additionally, he replaced the SZ-8 tube with a more common Z650M.  The top and bottom are .64 gauge aluminum for weight and the sides and back are .32 aluminum.  I'm impressed:

John found a great dekatron based Nixie clock on YouTube that I wanted to re-post here.  All of the timing is derived from the mains line at 50Hz.  The dekatrons divide the time base in to seconds, minutes, and hours.  I've contacted owner and others have as well to see how he performs the "divide by 5" function to get 1pps and the "divide by 6" to convert 60 seconds in to a minute.  You can see the jump/division happen at 1:20 seconds in the video.  I am not sure if this is simply a matter of wiring the dekatrons differently or there are other components in use that are not visible.

If you have an idea how this works, please leave a message in the comments and I will update this post.

UPDATE 7-7-2010:

Be sure to read SLvik's response in the forum.  He shared a photo of the back of the clock and confirmed The 50Hz mains is rectified and then divided down from 100:10 and 10:1pps by the two dekatrons at the bottom.   Very nice work!

Lastly, be sure to check out Kahlo's link for his schematic of a 50Hz divide by 5 & 10 design.  This help quite a bit: http://kahlo.redirectme.net/~kahlo/forum_jogi/Dekatron_Zeitbasis.png (thanks for sharing!)
