Coffee.js? How I hacked my coffee machine using JavaScript

on YouTube ↗39m

" summary

Hacked a consumer coffee maker by reverse-engineering its 8‑pin ribbon, finding that pins 1–3 supply power and pins 7–8 read buttons, and replacing buttons with relays to simulate presses. Code runs on Tessel 2 with Johnny-Five, exposes an HTTP API implementing a subset of RFC 2324 (uses application/coffeepot-command), and links to Alexa via IFTTT. The setup reliably opens relays to brew espresso on demand, proof that the build actually works.
