How I learned to stop worrying
summary
Builds a tiny device: a button, an RGB LED, resistors and a particle Photon microcontroller, with C-like device code that sends JSON over MQTT to cloud streams that filter the Twitter feed and emit RGB pixels, and a live dashboard that aims for a 100 presses goal. Demo uses pipeable Node streams and a rate limiter, mostly works despite a forgotten daemon and prior TSA and police hassles, shows concrete wiring, code, and a working dashboard.
