This clock features
New Old Stock, Russian made, IN-14 nixie tubes. These are stylish,
high quality, military grade, long life tubes with large 19mm
The slim case
was professionally manufactured from gloss black acrylic (Plexi,
Perspex with all edges polished), which beautifully mirrors the
nixies glow. Switches on the back select 12 or 24 hour modes,
set the time, fading or non-fading digits and LED under lighting
off, or a choice of three colours (Red, Blue and Purple).
The IN-14 nixie
tubes feature the quirky number 5
in Europe and the USA in the 1960's and 70's and in Russia up
to the early 90's nixie tube displays predate LED and LCD displays
and have a real "space age" look about them. Inside
a glass tube, ten solid metal cathodes are shaped to form the
digits 0 - 9 which, when lit, give off a warm orange / violet
glow that can be read from quite a distance.
With modern displays we have become used to straight lines forming
the digit segments - a zero is displayed as a rectangle - but
as each nixie tube digit has its own individually formed number,
curves can be used, so the figure "8" is a figure of
eight shape... not represented by a square on top of a square!
in the tubes are stacked in front of each other, so as the seconds
increase the digits seem to jump from front to back increasing
the animation of the display.
