Nixie Sudoku: Fun With Gas-Filled Tubes

by Paul Strauss

This has got to by my favorite Nixie tube creation in a very long time – a fully-playable Soduku board.

Trashbear Labs built this Nixie Soduku board using 81 individual tubes, arranged into a grid, and controlled by a couple of dials and a keypad. There’s even a built-in solver algorithm, in case he gets stuck trying to solve a particularly challenging puzzle.

Want one just like it? Trashbear has been kind enough to share all of the schematics, source code, and design files in one handy .ZIP archive here.
