Icosahedric stabilized LED display

bouLED is a LED-covered icosahedron that can display images. Thanks to an AHRS attitude sensor, the images are stabilized so that they appear not to move when bouLED is rotated. Each facet of the icosahedron is a PCB that carries 79 of the classic SK9822 RGB LEDs (1580 LEDs overall). We ordered APA102C LEDs but received SK9822 clones (even nicer, in fact). Even though it is not shown in the gallery, bouLED is typically inside an acrylic sphere for protection. bouLED was Hichem Ghandri, Lucas Lebailly and Matthias Rabault’s graduation project for Tlcom Paris’s masters-level degree in embedded systems.”
