Here are pictures and videos of my clock from when I first started trying to make it work, to making it work. Also includes the original schematics that my father designed. He designed and built it in 1969.

Lovely! Does it still work with the 1969 parts? Interesting to see that people even back then were interested in hobbyist nixie clocks!

That's really cool !

For being 50 years ago, that's a really impressive hobby project. Cool thing you made it work again !

Very nice indeed!

Obviously two projects really. The PSU is from another project and the 5V supply is a professional one with proper regulation and crowbar protection. The write-up is that of a professional engineer too - who did he work for?

Great to have restored it!

At the time, he worked for a company called Varian. He designed and built electrostatic plotters.

The 1PPS module no longer works, so a friend of mine put a Arduino powered clock module in to replace the those parts. The power supply and other logic circuits still function.

I love looking over hand drawn schematics. Truly a lost art.

It is ABSOLUTELY lovely! Thanks for sharing. I know (knew) Varian Data Machines well early on in my career. (A division of Varian at the time.)
