Next tram, bus or ferry board

Show the next departures from the stop, pier or tram platform you actually use, on the same small display as a station board.

Make it useful to you

Show the next departures from the stop, pier or tram platform you actually use, on the same small display as a station board.

CAIBI’s proposed addition: Find a live-times feed for that operator and read its terms; many UK and US transit agencies publish one. Reuse the departure-board display and case.

Alternatives the code does not use

Rail Data Marketplace: For a railway station, the ESP32 departure board already combines rail, Underground and bus routes.

Check the source before buying

Review the source material I supply for Next tram, bus or ferry board. Make a table of what is provided, missing, contradictory or dependent on a paid service. Identify exact hardware revisions, firmware files, library versions, CAD files and licences. Separate creator claims from your proposed additions. Do not fill gaps with guessed specifications. Finish with one small test that can resolve the biggest uncertainty before I buy parts.

Plan the next step

I want to develop this idea: Next tram, bus or ferry board. Intended outcome: Show the next departures from the stop, pier or tram platform you actually use, on the same small display as a station board. The source is https://github.com/chrisys/train-departure-display. CAIBI suggests: Find a live-times feed for that operator and read its terms; many UK and US transit agencies publish one. Reuse the departure-board display and case. First inspect the source I supply. Separate what it already does from proposed additions. Ask for my actual board, parts, skill level and missing files. Produce a small staged plan with one bench test per stage. Do not invent pin assignments, dimensions or completed test results.

Design a measured enclosure

Help me design a practical enclosure for Next tram, bus or ferry board. First ask for measured component dimensions, mounting holes, connectors, cable clearance, ventilation and operating conditions. Suggest a printable or off-the-shelf approach. Begin with a fit-test piece before a complete case. Label assumptions and do not invent an enclosure rating.

Check and document the result

Create a test log for Next tram, bus or ferry board. Intended outcome: Show the next departures from the stop, pier or tram platform you actually use, on the same small display as a station board. Separate expected behaviour from observed results. Include power restart, disconnected inputs, communication failure and the actual physical use. Ask me to provide results, firmware versions, changes, photos and unresolved problems. Never mark a test passed without my evidence.
