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.
