Hi Guys 
This is an easy, but potentially functional project to use a vintage Nixie Electronic Counter
as a real time clock display without any modification to the counter itself.
I used an old HP 5216A Electronic Counter of about 1970.
Above link is first of three videos about it done over a few days,
and a zip package containing schema, source, and binary should be attached.
PCB is up to you if you want one. Mine is dead bug on protoboard.
Cheers, Brek.
Mod edit: expanded .zip file for easier reference.
