It shouldn't be that difficult to provide some 'reasonable' readings. I think the software problem can be easily solved using an 8266 or ESP32 and 'Tasmota' software incl. MQTT protocol for connecting to the 'Iobroker'. A bamboo-wood cutlery box (IKEA?) could fit as a housing. Just like that as a suggestion ;-)

If you've been doing your hobby for many decades, a lot accumulates in the craft box that can no longer be used in a contemporary way, but is always a good idea for a 'work of art' :-) Let's see what I can find in my boxes, for yourself if it doesn't turn out to be 32 measuring devices ;-) Great idea :-) :-)

Where did you manage to acquire so many gauges? I have been hunting around for some but have not been able to ever find this many.

Mostly on Amazon and eBay. Most of them are between $5 and $10.

Do you know what those meters used in the Apollo command module for the O2 tank levels are called?  I'd love to use them in a project but can't figure out what to google to find them.  They don't appear to be "level gauges" or "vertical pressure gauges".

I consider  meter movements to be art.  Wouldn't it be cool to interface them with random things like stock prices,  specific audio frequency, distance to the moon etc.

You are right, I was thinking about many parameters - temperature, humidity, wind, air pressure, time, date, inflation, Covid, ISS position etc. But then I just remembered that so many new project are waiting to be built... :)

However, there is still the chance for the upgrade. There is an aux serial in, and MCU has the ability to control all 32 analog levels.
