Hands-on Bash-first guide for Linux tinkerers to build reliable, private, edge AI IoT on modest hardware. Covers why on-device AI matters, cross-distro setup (apt/dnf/zypper), and three reproducible projects: TFLite webcam classifier, MQTT+Node‑RED wiring, and vibration anomaly detection with Isolation Forest. Adds systemd services, MQTT security/tips, and next steps to publish to MQTT, build dashboards, and scale.

Turn a Linux box into a real-time IoT brain with a few Bash commands and mosquitto-clients+jq: subscribe to MQTT sensors, score readings via a tiny Python AI (or cloud API), and publish actuator actions - packaged as a resilient systemd service. The guide gives installs, scripts, and copy-paste pipelines, plus security tips, troubleshooting, and patterns for HVAC, maintenance, and cold-chain - scalable, private, and edge-fast.
