Astro clock
My latest completed project has been my Astro Clock. A simulator can be found here. This is a 24 hour clock that tells the time by showing the sun traveling around the face. This is not a solar clock, however. When the sun is at the very top, it is noon local time. Sunrise and sunset are indicated by the horizon lines visible during the day (meaning that during daylight savings time, the horizon is tilted!) The planets are also visible, roughly corresponding to their positions along the ecliptic.
After making the simulator, I actually built a real clock, with 60 RGB LEDs, running the same code (well, almost the same code. It also has a mode where it just shows regular 12h clock hands.) It’s currently hanging up at my parent’s place. The hardware consists of the LEDs, a real time clock, and an Atmega processor; you could easily replicate this with an Arduino. I’ll post the code on GitHub at some point...
