The Nixie Modular Clock! Akafugu’s Nixie Clock Redefined!

The Nixie Modular Clock is a fun to build stylish clock kit that uses old-fashioned neon Nixie tubes.

Nixie tubes were once the dominant type of display in early electronics devices such as multimeters, calculators and military equipment. A nixie tube contains a single anode in the form of a wire mesh and usually ten cathodes, generally in the shapes of the numbers 0-9. Nixies with other symbols are also common. By applying around 170-180 volts between a cathode and the anode, the cathode will light up in its characteristic yellow neon glow.
