This kit includes everything you need to build a 4 digit Nixie tube clock - the perfect "little brother" to our classic clock. While once the standard for digital displays, Nixie tubes have since (and since meaning a long time ago!) been replaced by LED, LCD, and Vacuum Fluorescent displays. Nixie tubes were 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..
