Given the presence of Rust, I was hoping for actually calculating the tides based on the rotation of the Earth, orbit of the Moon, etc. But reading the article and comments, I realize how much more complicated that process would be than "just" modeling orbital mechanics, gravity, and fluid dynamics. Cool DIY project nonetheless. Makes me want to dust off one of the Pis I have sitting around. I've never used the GPIO for anything, and it sounds like I'm missing out.
