From Software to Hard ware: How Do I Track My Cat with JavaScript
summary
Describes building a cat tracker that detects motion, captures images, runs JS cat-face detection, uploads photos and sends SMS alerts. Uses Raspberry Pi camera module, PIR motion sensor, Node.js with Johnny Five and child processes, and the open-source Kittydar detector. Forked worker handles expensive image-to-canvas processing; Cloudinary stores images and Nexmo sends texts. Demos include wiring, spawn/fork commands, measurable false positives and iterative retraining; RFID and camera upgrades are planned.
