Escaping the Sandbox with Puck.js

on YouTube ↗16m

" summary

Shows that Puck.js running Espruino executes real JavaScript on-device so web pages control hardware via Web Bluetooth, not just demos. Claims devices run for a year on a watch battery and exposes a serial-like REPL and APIs (NRF, characteristics). Demonstrates a sweet dispenser that dispensed sweets via stepper motor from a webpage, using a tiny on-board JS server and a helper library to handle BLE quirks. Mentions low power, upcoming Bluetooth mesh, and an over‑BLE debugger.
