Created by the Ruiz Brothers with code by Phillip Burgess, this interactive electronic plaything uses motion sensors and a Raspberry Pi computer to determine the flow of digital grains of sand on a 64×64 matrix of LED pixels. You can grab the schematics, parts list, code, and build guide over on Adafruit.
THE BEST Adafruit
The guys from electronics site Adafruit Industries show off a fun project you can make for yourself – a trampoline with a cool LED light ring. The lights aren’t just colorful, they can be triggered based on when you jump up and down. Full build guide and parts list here.
Adafruit shows us how to make an electronic and portable dice roller. It uses a small motor to spin a small platform, which in turn rolls the dice. As others have pointed out, it would be better if you make the platform uneven to shake the dice even more. Full guide here.
