Kit w/o Tubes $299
Assembled w/o Tubes $349
This is my clock. I am the proud owner of the last one made according to the creator himself. The display in this clock is a Russian Nixie tube called an IN-18 / ИН-18. This is a really odd display. There are 10 filaments inside of the tube. Each one is shaped in the form of a number. The tube is then filled with neon gas and a little bit of mercury to prevent cathode poisoning. When ~180vdc is applied to one of the numbers, it glows.
Six of the IN-18 / ИН-18 tubes are used to display the time. Like the Scope Clock, the time is set via GPS but a built in clock keeps the clock going when a signal cannot be located. The tubes are some of the largest that were produced in quantity which adds a collector value to the clock. Since they do wear out, I have a second set stored in a hard Pelican case.
As of 7/22/2009, the clock is once again for sale. It is now being offered fully assembled for $349 or as a kit for $299. If you're looking for an IN-18 clock, this is the one to get! http://www.amug.org/~jthomas/nixikit.html
