JavaScript on the Raspberry Pi
summary
Raspberry Pi is a $25 computer that boots Debian, uses an ARM11 700MHz CPU with a powerful GPU capable of full‑HD 60fps rendering, and runs Qt 5 / Qt Quick (QML) with V8 to drive GPU shaders and real‑time animations. GPIO pins get exposed to QML via a C++ plugin so JavaScript can toggle LEDs and solenoids; a 24V power supply plus a Darlington switch is required, the live music demo uses solenoids and mostly works but fries boards if miswired.
