【PIXEL DESIGN】IN-8-2 NIXIE TUBE CLOCK

by Pixel Design

Price: TBD, currently $103 on eBay

I just found this clock on eBay from a new seller, Pixeldesign2009.  It is based on a Russian IN-8-2 tube and has a built in time base.  No more information is provided via the auction other than it has a "built in RTC clock."  I am guessing that it is just an inexpensive mechanism as precision does not seem to be the focus of this device.  Additionally, based on the description, this appears to be 24-hour mode only.  Lastly, no information is given on whether this is a directly driven display or multiplexed.

With all of that said, this could be a nice addition to any collection.  The tubes are pretty small and while no dimensions are given, I am guessing the clock is no wider than 6 to 8 inches. The case appears to be a black plastic and does not appear to be a kit of any kind.  For $100, this isn't a bad deal.
