I'm surprised no one has mentioned this tube on here. 70mm digit height. Here next to an IN-18 for scale:

They claim an unlimited service life on their website....that's a bold claim! How does it look in real life Paul?

I've been running one 24x7 for a couple of weeks - not quite pushing the envelope of unlimited but no signs of any issues so far.

I have just completed a 6 tube clock using them though I only have one tube so will be having some trick photography done this weekend to show what it would look like fully loaded - the recipient of the clock has hs tubes waiting!

I also took one of their colon towers which are nicely made.

The tube is available in both Z568M compliant base and their own proprietary base which consists of two rows of 0.1" pitch male headers (like the ZIN18 - although I see that is now available in an IN-18 compliant format).

I found some nice 'pin sockets' that are press fit into a PCB and work well on a 0.1" pitch - my only 'complaint' being that the base of the colon towers cannot sit flush against the PCB because of the plastic carrier for the 0.1" pitch pins though I expect that this can be pulled off.

I used the Z568M tube base so that other tubes with the same base could also be used.

The Millclock colon towers do not support any under tube lighting so, for a different board, I have come up with a solution for under lit colon towers that will match the base of the black or silver versions of tubes from Dalibor and Millclock.

Do these nixies have symbols for temperature (F and C)?

I've ordered one ZIN-70 Tube two days ago. You can choose, which special character you want to have °C or °F. They can only add one special char. It's really awesome, that the tube can display a temperatur unit and the digits 0 - 9.

I was surprised at the price of 129 USD. If my backlog of projects was months instead of years, I would buy one and see how durable it is.

Why does it look like the ZIN is being overdriven in this video?

The anode resistor i used in the Youtube-Video was 3K3. That's the value Millclock told me. I've changed the anode resistor to 4K7 - now it's looking better (picture attached).

Do you know what current it's drawing? Comparing your video (nice!) to the millclock videos, your tube looks significantly brighter (almost too bright), which makes me wonder whether you may have a lot of sputtering and darkening of the glass after prolonged usage.....

with a 4K7 anode resistor it's 6mA @ 170V ... Millclock told me, that 6mA is ok.

Sounds about right. The addition of the symbol is a nice touch. Will be interested to hear about the longevity of these. Thanks for sharing the comparisons Roman!
