Bivariate Bivalves

Electronic LED map, updates daily with water toxicity and tide data.

A little experiment in electronics that tells me when I can go digging for clams. Clams live in subtidal zones and are only accessible to us during low tide. They can also kill you if the water is poopy: clams eat by filtering nutrients out of the water that they take in and push out via two valves. This map is powered by a Raspberry Pi that runs a script to process daily water toxicity and tide data, and updates the color of LEDs depending on the clammability of a particular location. I talked about this project at NACIS 2023 [YouTube].
