The Akafugu Nixie Clock is a fun to build stylish clock kit that
uses old-fashioned neon Nixie tubes.
New in mk3:
- Socket pins added to the nixie tubes
- New design for high voltage supply for better efficiency
- Potentiometer to set voltage dropped and replaced by 1 % resistors
- Various minor fixes to the routing of all the boards
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 anodes, 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.
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.
