Very cool but I find a pi is overkill for something like this. ESP8266 or ESP32 would work just as well.
That is super cool. But admittedly when I saw the title i was hoping for a mini version of those massive flipboard signs. Those things are amazing.
As an indirect result I now have a project in the works to make them. The concept is simple, but building them to be inexpensive is a challenge. Every extra bracket or fastener gets multiplied by _n_ modules.

They would, but the Pi Zero is a much better UX for people who don't deal with microprocessors on a regular basis. It has SSH, I can get in and look at logs from my desktop, wifi is standard. It all adds up - and for something like this, the power draw is not an issue, and the cost is minimal.
wow, crazy how small Pi has become! I remember trying to do a similar project for the bus stop at the corner of my street to know when to leave to catch the bus. It was fun, but I never really finished when I realised how big just the Pi would be (still powered by usb-a, etc). Nice to see this one so well executed!
Happy to answer any balena (or train station sign) related questions, of course :)
One thing that always annoys me with those signs is when they try to put too much information on them. You have all of the stops, fine. You then have all of the information about the train splitting which you might well need. But then they start adding information about short platforms etc. It takes several minutes for it all to scroll past. Which is super annoying if you're trying to work out if the train standing there stops at your station.
