Six big IN-18 digits in a clear acrylic case
The IN-18 is the largest classic Soviet nixie tube, with tall, elegant digits. This clock lines up six of them in a clear acrylic case that shows off the tubes and the black circuit board: our most accessible six-tube clock. Assembled and tested by hand in Paris.
Light and effects
- RGB LED backlight under each tube: 10 levels per primary colour, with a different setting for every hour of the day (bright by day, dim at night)
- Neon colon lamps between hours, minutes and seconds
- Crossfade and “slot machine” effects
Timekeeping
- Quartz crystal oscillator for accurate time, independent of mains frequency: works anywhere in the world
- 12 or 24-hour display and date display
- Alarm with snooze
- One-button daylight saving time
- Supercapacitor backup through short power cuts; settings stored in non-volatile memory
- Optional GPS or WiFi time sync
Built to last
- Night mode: dims or blanks the display at night
- Anti-cathode-poisoning routine: the slot machine effect regularly cycles every digit to keep the tubes healthy
- Optional motion sensor: switches the tubes off when the room is empty
