Hunter's comment

For all you space nerds out there this pin is a nice little open source project to build yourself that lets you know when the International Space Station is passing in the sky over you. A white light orbits the pin most of the time but when the ISS passes in the sky over you its starts to flash multiple colours.

A Particle Photon microcontroller and an Adafruit Neopixel ring combine to make a pin that's fit for NASA fans. It displays an orbiting white blip when idle and then turns blue, white, red and multicolor when the ISS flies by.
