Another handmade Nixie tube clock has been included in our shop! The Six Digit Nixie tube Clock The "Caso Chiaro"...

We have taken six genuine N.O.S. (new old stock) Russian type IN-16 Nixie tubes from the Cold War Era and created an art form time piece that is sure to please even the most particular Nixie tube clock aficionado. Nixie tube clocks blend the spirit, drama and eerie beauty of cold war technology.

This clock is micro controller controlled. The quartz oscillator used is a low-drift temperature-compensated type, giving accurate time for years to come. High voltage is supplied by a high efficiency switching power supply. It is powered by the included high efficiency switching 12 volt D.C. adapter for North American mains. The Nixie tubes are type IN-16 tubes. Nixie tubes, unlike other vacuum tubes, do not have a filament. This has two major impacts on the operational characteristics of the clock. Nixie tubes produce very little heat, and as such, do not require the kind of ventilation that other vacuum tubes need to function. Also, the tubes' operational lifetimes are greatly extended past that of regular vacuum tubes.

We have taken some of the old technology and blended it with modern day electronics to produce a piece that is truly unique. This clock measures 7 inches X 3 inches X 3 inches which can be perfect on your dresser as well as on the desk in your home or office.

The case sides are clear cast acrylic plastic . The top and bottom is shiny black acrylic. There are four soft plastic bumpers on the bottom to protect your table or desk. The blue underlight LEDs blue glow shows through the case sides and looks quite lovely at night. Of course you can turn them off if desired.

Nixie tube prices have climbed steadily over the years and they are becoming very hard to find. Since no more will ever be produced the value of these clocks should increase as well over time. Why not buy something that is beautiful, tells time and most likely will appreciate in value over the years? The choice is yours!....
