Setting Fire To My Desk: Adventures in Redis and Microcontrollers
summary
Connects a $1 ESP8266 microcontroller directly to Redis by implementing RESP protocol on the device, reads temperature with a DS18B20 sensor, and streams data into Redis streams (replacing sorted-set hacks) visualized by a Node.js/Express dashboard and WebSocket->D3 front end. Demonstrates Wi‑Fi auth, NTP timing, deep‑sleep battery tradeoffs in subzero testing, and a working prototype that reliably samples ~500 ms and survived a soldering‑station fire.
