Rekindling a love of creation with Ruby and Raspberry Pi
summary
Builds actual things with Ruby on a Raspberry Pi: flashes an LED via the RPIGPIO library, teaches breadboard wiring and resistor sizing, and wires a giant whoopie cushion prank as a GPIO-triggered sound player. Moves a chassis with cheap stepper motors driven in a half-step sequence — about 512 half-steps per revolution — and mounts parts via a Thingiverse 3D print, though battery power and runtime turn out to be finicky.
