DIY: Compact Nixie Tube Clock Kit

@ May 12, 2012


DIY kit to build a Nixie Tube Desk Clock. High quality nixie tubes. Nixie tubes were considered cold cathode tubes filled with neon gas with a wire mesh anode and a set of very intricate cathodes in the shape each of the numerals to be displayed.


This little clock uses 4 Siemens ZM series nixie tubes that measure approximately a .5" in diameter by 1.75" high. The hour/minute separator is a classic NE2 style neon bulb.

The clock features 12/24 hour selectable operation, and leading zero suppression. The tubes mount in a unique double set of boards that can be easily integrated into your own enclosure or equipment.

Unlike today's digital displays that run on a few volts, these Nixie tubes have an anode voltage of 180VDC, and the clock should not be displayed turned on without a suitable enclosure! Ouch!


The clock assembly measures 4.33" x 2.16" x 2.36". If a modernistic style case is more up your alley, check out the optional dark tinted plexiglass enclosure for a futuristic look (5.12" x 2.95" x 1.37") is also available. Both cases would certainly be an attention getter at anyone's home theatre shelf, desk, or table!

Technical Details:
  • Microprocessor controlled!
  • 12 or 14 hour selectable display mode!
  • Tube blanking option!
  • Stylish enclosures available
  • Electronic Kit - Assembly Required.
