SUBWAY TIME

An LED-matrix NYC subway, Citi Bike & weather board, living on an old Android phone.

Live demo: the real board code, with sample trains.

What it shows

• Next trains from Franklin Av (2 3 4 5) and 7 Av (B Q), every train in the next 15–25 min, the ones too soon to catch dimmed
• Time to 42 St from the live feed: Times Sq, Grand Central or Bryant Park, depending on the line
• Weather with a pixel icon, high/low, humidity and rain chance for the next 3 hours
• Citi Bike bikes at two nearby stations, open docks at two more
• A big clock with a blinking colon
• A Siamese cat that walks the black strip covering a cracked corner, turning liquid to squeeze past the camera

How it works

A small Node server runs in Termux on a Galaxy S21 and pulls the MTA's realtime feeds, Citi Bike's station status and Open-Meteo, no API keys needed. Chrome shows the board full screen. Any other device on the same Wi-Fi can open it too.

It's built to live on a charger: the screen goes dark at night, the panel shifts a dot every few minutes against burn-in, and charging stops at 60%.
