Classic Nixie Clock

This clock was made from an actual vintage ringer box.
The electronics are based off of Arduino while the display is made with Nixie tubes.

A Nixie tube is a display tube first introduced in 1951 by Burroughs Corporation that displays numbers 0 through 9. These tubes were found in early electronic devices, such as calculators, frequency counters, voltmeters, and other devices, that needed a method of displaying numeric values.
