Nixie Tubes – a Blast from the Past

In the midst of the all my computer chaos I’ve also started another project – building a Nixie Tube Clock kit.

What are Nixie Tubes?  They are a Cold Cathode Display Tube harkening back to the Cold War.  For the most part most Western Countries dropped Nixie Tubes in the Early to Mid 1970s, but the former USSR kept them in production another 20 years.

The Clock Kit I’m doing was sold by a UK based Nixie Specialist and uses the IN-12 & IN-17 size tubes.

I’ve something quite different in mind for my case.


Former USSR countries are  the primary source for bulk Nixie Tubes, and though these tubes have rated lifetimes measured in many decades bulk packs of spare IN-12 & IN-17 tubes were also sourced, along with a good supply of the FET transistors and driver micro chips for further experimentation.

Will do some build pictures for a follow up.
