About Nixie Tubes and Nixie Clocks:

Nixie tubes are vacuum tubes displays widely used in electronic equipment during the Cold War Era.
Developed in the mid '50s by Burroughs, nixie tube displays were the very first electrical numeric displays.
Nixie tubes utilizes the phenomenon of glow discharge of neon gas when high voltage is applied.
Their principle of operation is basically the same as a regular neon lamps widely used in light switches.
One major difference is that the nixie tube uses ten cathodes-digit resembling handwriting numerals.
During Cold War Era nixie tubes were commonly used in first computers and measuring devices.
In the late '80s nixie tubes were superseded by more modern LED, VFD, and LCD displays.
However, in post-Soviet Union states nixie tubes were still being mass-produced till the late '90s.
New Old Stock nixie tubes (NOS) can be still found in old military surplus warehouses in Russia.
Unlike LED, VFD or LCD displays, nixie tubes have this unique, mesmerizing and mysterious orange glow.
Nowadays nixie tubes are once again revived in unique clocks, which bring memories of the Cold War Era.
Because of this nixie clocks are increasingly popular among steampunk and retro enthusiasts.

Item description:

Nixie tube clock displays time in HH:MM:SS format on 6 Z570M nixie displays.
Connection of nixie tube displays with modern electronics
constitutes this original and intriguing timepiece.
Tubes are brand new and comes from old stock (so called NOS).
Tubes have removed red filter for better backlight visibility.
Tubes are installed in individual PCB boards with sockets for easy removal.

Offered clock is assembled with the use of new, high quality parts and tested.
Clock’s case is made from fiberglass composite with green gelcoat.

Clock features:

  • Hours, Minutes and Seconds display
  • RGB backlight with 99 colors available (can be turned on/off)
  • Selectable 24 or 12 hours time displaying format
  • DS3231 RTC module with battery backup ensures high accuracy
  • Software time correction (maximum time deviation without calibration is +/-5s a month)
  • Simple time, date and menu setting using only two buttons
  • Optional date displaying every 1 min
  • Optional crossfade effect (digits morph from old to new)
  • 8 modes of neon colons (colons flash at 1Hz On/Off or indicate AM/PM time)
  • Optional leading zero blanking
  • Auto increase of adjusted value after holding button for 2s (enables quick setting)
  • Maintains time during setup (useful when changing between Standard Time and Daylight Savings Time)
  • Seconds can be reset to zero to precisely set the time
  • 6 brightness levels of tubes & backlight
  • One button for switching LED backlight On/Off
  • Programmable timed LED backlight blanking mode
    (backlight can be turned off to reduce glare during night)
  • Programmable timed tubes dimming or blanking mode
    (tubes can be dimmed or blanked during night for extending their life expectancy)
  • Programmable tubes exercising routines
    (tubes exercising prevents
    cathode poisoning and extends nixie tubes life expectancy.
    3 exercising routines available - cycling, cycling with scrolling or slot machine

    every 0, 1, 10, 60min or 24h)
  • Settings are stored in nonvolatile EEPROM memory (clock keeps settings during power outages)
