A rather large 7-segment, 4-digit clock powered by a Particle Photon. Synchronizes time with the Internet (using built-in wireless), display local (as in a sensor inside the clock itself) temperature/humidity, and display current outdoor temperature and humidity. There are a couple of different display modes (solid color, chasing rainbow), and is fully configurable via REST API. I am also working on a mobile web app for easier configuration of the clock! See the instructions for more details.Tools Needed Things to Buy (if you don't own them already) Things to Print (in ABS if you can) Assembly Instructions Electronics The Code The code I have written is for a Particle Photon or Core. It should be trivial to port it to an Arduino, or any other platform that uses Wiring / C / C++. Source code available via this GitHub repository.
