Hi,
I'm thinking of creating a Nixie clock controlled by mechanical 5V relays.
I won't do anything fancy, just static drive with the Nixie anode connected
to 180VDC through a resistor and one relay for each cathode. The relay coils
will be connected to uC pins via either individual transistors
Maybe you can use DS3232M or DS3231M? They are both soic-8, and share the
same command set.

Well see, maybe when they shrink them down to chip scale. I'm finding the
DS3232 to be a bit on the large size these days.

Hi,
You can use bistable relays with one coil, they change state for every
pulse, so to turn them on you pulse them once and to turn them off again
you pulse them once again - there are also bistable relays with two coils
where one coil is used to turn them on and the other to turn them off.
If you are going for the click sound, also consider using a 10 position stepper switch. One stepper can control an entire digit and
could be used to advance the next stepper. These, and other like them were used in rotary phone systems. Some of those have a
release relay, so you can reset a
Thanks for the tips... bistable relays seem to be the way to go, at least
for a prototype.
Stepper switches / uniselectors look fascinating, and I may go for that
instead if I can source some.
