- Project: a Wi-Fi temperature and humidity monitorBuild an ESP32 temperature and humidity monitor in MicroPython that publishes readings over MQTT with TLS, with a parts list, wiring, build steps, code and a security checklist. 9 min · Beginner
- Project: a home security door/window sensor with alertsBuild a battery-powered door or window sensor with a reed switch and an ESP32 that wakes from deep sleep, reports over MQTT and sends heartbeat messages, plus a threat review and security checklist. 9 min · Intermediate
- Project: a smart plant watering systemBuild an automatic plant watering system with a capacitive soil moisture sensor, an ESP32 and a small pump, including calibration, fail-safe limits, MicroPython code and a security and safety checklist. 9 min · Intermediate
- Project: an MQTT sensor dashboardBuild a self-hosted dashboard on a Raspberry Pi: Mosquitto as a secured broker, Telegraf to collect MQTT messages, InfluxDB to store them and Grafana to graph and alert, with configs and a security checklist. 10 min · Intermediate
- Project: a Raspberry Pi network monitor for your home or labTurn a Raspberry Pi into a network monitor that checks key hosts are up, spots unknown devices joining, measures traffic and logs DNS, with a Python script, build steps and a security checklist. 9 min · Intermediate
- Project: building a safe, segmented IoT test labDesign and build an isolated IoT test lab with VLANs, a firewall, packet capture and DNS logging, so you can study and test devices safely, with a rule table, build steps and a lab safety checklist. 10 min · Advanced
- Project: a Bluetooth Low Energy asset trackerBuild a room-level asset tracker in which ESP32 scanners listen for Bluetooth Low Energy tags and report signal strength over MQTT, covering RSSI limits, MicroPython code, privacy and a security checklist. 9 min · Advanced
- Project: a smart energy monitorBuild a whole-home energy monitor that reads your electricity meter's pulse LED with a light sensor and an ESP32, calculates live power and daily energy, and publishes it over MQTT, with safety and security guidance. 9 min · Intermediate
