Tide times for your nearest harbour

Show the next high and low water for one tidal station on a low-power e-paper panel.

Not yet assessed Not built by CAIBI

A source to explore and a proposed direction to develop. This is not a full build assessment.

Make it useful to you

Show the next high and low water for one tidal station on a low-power e-paper panel.

CAIBI’s proposed addition: Choose a tide source and check its terms: NOAA publishes US predictions openly, while UK predictions from ADMIRALTY are offered on subscription tiers. Adapt the e-paper weather layout.

Check the source before buying

Review the source material I supply for Tide times for your nearest harbour. 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: Tide times for your nearest harbour. Intended outcome: Show the next high and low water for one tidal station on a low-power e-paper panel. The source is https://github.com/lmarzen/esp32-weather-epd. CAIBI suggests: Choose a tide source and check its terms: NOAA publishes US predictions openly, while UK predictions from ADMIRALTY are offered on subscription tiers. Adapt the e-paper weather layout. 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 Tide times for your nearest harbour. 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 Tide times for your nearest harbour. Intended outcome: Show the next high and low water for one tidal station on a low-power e-paper panel. 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.
