Richard Saville (aka Average Man) lives in Southend-on-Sea, which puts him on the East coast of England. He has taken one of his prototyping boards (the ProtoPal) and the components contained in the RasPiO 7 segment display kit and created a high tide display. It uses a public API to get the next high tide time and then pushes that to the 7-segment display. He has also laser-cut a case to go around it. It’s a great little project and he has written it up into a tutorial with annotated code and everything you need to re-create it. Read how he did it here.
