Description
Table clock assembled using vintage Soviet IN-14 cold cathode tubes.
The tubes are 1980s vintage – New Old Stock (NOS) – were not used.
Their factory warranty is 5000 hours of operation, but thanks to the protection from cathode poisoning, realized in this clock, the tubes can work for several decades.
The case is made from mulberry wood and covered with wood stain, patina and high-quality polyurethane varnish.
Features:
– Time format: 12/24 time display
– Indication: hours, minutes, seconds
– Blinking bulbs with adjustable duration
– Selectable date display (from second n…to second m of every minute)
– Adjustable date format (DDMMYY, MMDDYY, YYMMDD)
– Selectable blanking of leading zeros
– Automatic daylight saving time correction (configurable)
– Selectable digit cross fading
– Selectable „Slot machine“ every n minutes to prevent cathode-poisoning
– “Night mode“ – tubes can be switched off for a selectable time
– Alarm clock
– Tubes can be dimmed by key-press: full+fading, full, half, off)
– Tubes can be switched on by key-press during „Night mode“ (slot machine and date
display are suppressed)
– Tubes are switched on during alarm in „Night mode“ (for a selectable time)
– All settings are saved in the EEPROM and will be kept in case of disconnection to mains
– Power adapter with EU or US plug is included
– The clock accepts 110V and 220V in both frequencies, 50Hz and 60Hz
– All options (start/end times, intervals etc.) can be configured with 2 switches (the third is
for the alarm handling) during operation.

Cold cathode display – is an electronic device used for displaying numerals or other information using glow discharge.
The glass tube contains a wire-mesh anode and multiple cathodes, shaped like numerals or other symbols. Applying power to one cathode surrounds it with an orange glow discharge.
The tube is filled with a gas at low pressure, usually mostly neon and often a little mercury or argon, in a Penning mixture. Although it resembles a vacuum tube in appearance, its operation does not depend on thermionic emission of electrons from a heated cathode. It is therefore called a cold-cathode tube (a form of gas-filled tube), and is a variant of the neon lamp. Such tubes rarely exceed 40 °C (104 °F) even under the most severe of operating conditions in a room at ambient temperature.
Vacuum fluorescent displays from the same era use completely different technology—they have a heated cathode together with a control grid and shaped phosphor anodes; cold-cathode tubes have no heater or control grid, typically a single anode (in the form of a wire mesh, not to be confused with a control grid), and shaped bare metal cathodes.
