Gadget Freak Case #199: Nixie Millivolt Meter Clock Add-On

When James Hartnett found a Nixie, a tube for displaying numerals, he instantly decided that he needed to make a clock.

It was only recently that James Hartnett came across Nixies -- those tubes for displaying numerals. James loved "that awesome display with the 3D-look and the glow of a tube-like device." When he found one, he instantly decided that he needed to make a clock. He found a Nixie Tube-based Volt Meter. "Volt meter" is a bit misleading -- it's actually a "millivolt meter," said Hartnett. When he decided to turn it into a clock, a Gadget Freak was born -- or created.

The circuit and breakboard.

Everything's working.

What the display will look like.
