The Akafugu Nixie 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 bewtween a cathode and the anode, the cathode will light up in its characteristic yellow neon glow.

The Akafugu Nixie clock comes in a 3 PCB modular design with a unique look that incorporates the PCB board into the case: The front and back panel are PCB boards, with smoke black acrylic lining the sides. The result is a strikingly simple and compact Nixie clock that combines modern and retro looks.

The clock is controlled and set using an innovative method involving a single push-button rotary controller and three indicator LEDs on the display board.

We are currently shipping version 3.0 of the clock, which includes pin sockets for the nixie tubes. This allows swapping out tubes easily.
