Large Glass Clock #3 IN-8-2 - special version of the Large size Glass Nixie clock.

Sockets for the Nixie tubes are now standard on the IN-8-2 clock. Socket pins allow solderless replacement of Nixie tubes. The socket pins are very small and do not change the look of the clock. If a tube fails, though, the sockets allow the tube to be easily replaced.

This version of the Glass Clock Large uses the rare Cold War era Soviet IN-8-2 Nixie display tubes, instead of the IN-14's that are used in the standard Large Glass Nixie clock. Both tubes have the same 18mm size digits, but the IN-8-2's are a more expensive tube - see tube comparison photo for differences. The '5' digit is better formed in the IN-8-2 tube.

The Glass Clock is designed to mirror and complement the Nixie tube's vacuum tube
shape and construction - from the round glass tubes used in the case to the round shapes used in the acrylic support pieces. The case is made out of Simax glass from the Czech Republic, and is hand cut and polished.

This handmade clock, including the electronics and software, is designed and manufactured by Cold War Creations. It is not built from a 3rd party Nixie clock kit.

The circuit board is designed by Cold War Creations, specifically for the Glass Nixie Tube clock, assuring a perfect match to the case design. The circuit board is also designed with micro-miniature surface mount parts, shrinking the size of the board to emphasize the Nixie tubes and downplay the modern circuitry. The CPU has more processing power than the large computers that originally used Nixie tubes! The PCB itself is manufactured in the US by a high quality circuit board house. Board assembly is by Cold War Creations.

The display has many options. Digits can crossfade, slide across, turn off at a programmable time interval, and a light sensor that adjusts the display intensity - the brighter the ambient light, the brighter the Nixie tube display and can also turn off the display when it is dark. Programmable colon modes available. A temperature sensor is also included for displaying the room temperature. Also, each clock is individually calibrated with an Atomic clock module for high accuracy.

* Displays time, date and temperature.
* New Auto-DST (daylight saving time) adjustment, adjusts the time when DST changes. US/EU/AUSTRALIA zones.
* Special effects: cross fade, slide across, and slot machine effect (these effects take place when digits change, or going from time, date, temperature.

* Programmable date format (mm-dd-yy, dd-mm-yy or yy-mm-dd).
* Temperature can be displayed in Deg F, or Deg C
* Auto display adjust (varies with ambient light levels)
* Programmable Display OFF/ON times.
* Auto display ON/OFF using ambient light level option, display off when dark.

* Anti-Cathode Poisoning function (extends tube life). Options for once a day, once an hour or once every 15 minutes.
* Standard Sockets for the Nixie's - easy replacement in case of failure.
* Country specific AC adapter included.
* Color instruction manual included.
* Unlike other Nixie clocks, Cold War Creations comes standard with a full 1 year warranty on clock & tubes.
