You might like to keep track of the tides; if so, this tide clock from [rabbitcreek] could come in handy. These days, though, you don’t need pulleys and ropes to build a tide clock; you can just use electronics for display and the NOAA API to get the information you need. [rabbitcreek’s] build is based around the Xiao ESP32 S3, which is charged with using its Wi-Fi connection to query NOAA up-to-date tide height data. If you’re a surfer or beach driver that’s always wanting to know the tidal state at a glance, this clock is for you. We’ve featured other tide clocks before, but never any projects that can actually influence the tides themselves.
