This was attempt at having an eclipse assistant to countdown to the different contact times based on GPS coordinates. It's powered by a Particle Electron with extra GPS receiver. It also contains several sensors: temperature, humidity, UV, visible light. Now that the eclipse is over, it has been retrofitted with a Particle Photon and the top has been screwed into place for a second life as a clock/message marquee.
