Developing Like There's No Tomorrow
summary
A wristband with an 8-bit microcontroller, 900 MHz radio, RFID, multicolor LEDs and a button connects to PoE base stations (Raspberry Pi–class nodes) that form a synchronized mesh; deployed maps use signal-strength triangulation with roughly 10–20 m accuracy from about 60 base stations per site and scale toward 100,000+ bracelets. PCBs are made in Singapore, prototypes assembled in Italy and packaged in Belgium. Over‑the‑air firmware updates are risky, batteries last a weekend, demos can fail but festival lightshows and crowd analytics do work.
