Astrarium is a persistence of vision planetary map, showing the angular positions of the 8 major celestial bodies (sorry Pluto!) on any given date between 1800 and 2050.

Using a segmented mask, Astrarium does away with the complexity associated with rotating arrays of LEDs and is capable of displaying a variety of graphics including analogue clock hands and the phases of the moon. Running at 5400rpm, Astrarium makes use of 3D printed optical baffles, concentric diffusers and an ARM Cortex-M0 processor to achieve a resolution of 8x360 pixels at 25 frames per second.
