- For
- Amsterdam-area commuters who want a departure countdown at home
- Worth noticing
- The DIY version uses a LilyGO T-Display-S3, needs no soldering, and can be flashed from a browser with one button.
Field notes
Setup runs through the clock’s own Wi-Fi: connect with a phone, choose the home network, then enter the displayed code in the app. The page says the device uses open public-transport data and will report when data is unavailable rather than inventing a departure estimate. A self-build uses a LilyGO T-Display-S3, with no soldering required; the ready-made version is marked as coming soon.
