A Raspberry Pi Tidy Tide Tracker Predicts Propitious Promenades

The whims of the tides can make walking near the ocean a less than pleasant experience. A beautiful seascape one day may appear as a dismal, mucky, tidal flat the next. Frustrated over these weary walks, [Average Man] created a tidy tide tracker to predict propitious promenade periods.

A Raspberry Pi A+ pulls tide timing information off the web by scraping a web page using Python code. The time for the high tide, when the estuary will be full of water, is shown on a 4-digit 7-seg display. It’s all sandwiched between two smoked black panels to provide a neat case while still letting the LEDs show through.

The code comes from two projects [Average] recalled from a kickstarter timing project and a 7-seg display project. As he points out:

It’s great to learn programming from others, but it’s even better if you learn them well enough to remember, re-use and combine that code later on as well.

The display chips are mounted on a product of his own, the no longer available ProtoPal board. This is a Pi A+ size board with 288 prototyping holes and the standard connector for mounting on the Pi GPIO header. It keeps the project neat and clean.

  1. I wonder, does this require more computing power than typical office desktop PC just to get some info from the Internet and display it? Next time shoot some ducks with heat-seeking missiles…

      1. Haha yes you could just go on your smartphone and check the same website I pull the data from, but that isn’t really the point of the Raspberry Pi is it.

        To make this I had to learn how to use Inkscape, how to code it in Python, up my soldering game and learn all about segment displays (common cathode).

        ^^ That is the point of this project. Not to make something new, it’s a fun way of putting all my learnings into a project and being happy with the output.

        Besides, I’d much rather have a 4″ display box on my TV unit than a full desktop PC!!

      2. It depends on the office. In my country Social Security still uses floppies for moving data. And because RPis here cost 4 times the american price, I find it a bit wasteful to use such overpowered device for such menial task. Besides doing this with ESP2866 and 8-bit micro would be more educational. And calculating tides with 8-bit micro would be even better…
