This is great! And it made me wonder if bus transport data in my city is available for everyone - we got few displays around, two services/applications that show the current position for each line...

Well, technically it's available for everyone if the system has an app then the app can be reverse-engineered quite easily to get access to the API.

Very cool but I find a pi is overkill for something like this. ESP8266 or ESP32 would work just as well.

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.

And constantly compiling and flashing the ESP gets old after a while.

I'm working on a pi zero version of my own at the moment. The National Rail Enquires api's (Darwin) are free to use at personal (and surprisingly large) scale. They may be SOAP but still easy enough to talk to with some simple python. https://www.nationalrail.co.uk/46391.aspx

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.

There's a great Github project for building your own Splitflap/Solari displays from the ground up for $20 each https://github.com/scottbez1/splitflap

They're really cool! The original Solari board modules are mega expensive though. I looked at getting some to make a clock, and it probably would have cost me in the thousands. 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.

Right now it's focusing on 40-character flaps (not super convent for clock-making), but it's open-source so I'm sure you could modify it for your purposes with some effort.

Why I can't use my old phones to do this is beyond me. I have one windows phone lying around and a few android phones. Everything is there in a neat package but the manufacturer make it so hard to tinker with them.

What's preventing you from using an old phone for this? There's no specific hardware (other than driving the display, which your phone already has), right?
