Two games built on bare-metal Raspberry Pi. (No images used -- made pixel by pixel!)
(1) "Clappy Bird": A Flappy Bird variant that is played by clapping (or making any other loud noises) instead of tapping.
(2) Pacman: Just the good ol' Pacman.
Laser-Cut Bike Phone Mount
Think segway, but fit for a travel-sized teddy bear. Built with Arduino Due, 6-DOF IMU, motors + encoders, and custom nested PID controllers.
