This project isn't dead! In fact the sign works fine. I have two of them in my apartment that survived a move and work for a new station now. The issue is, I'd like this to be more of a "look what you can make!" than a "look what I made" so, I'd like this to be a standalone project that can be built by anyone. Right now, the sign relies upon an external server feeding it data by looking at the subway real time feed, parsing and interpreting the data and sending information through various MQTT topics to the sign itself which listens for them. The image is the node-red flow that does this. So, it's a little complex right now, though functional.
