Full write-ups for every ESP32, HomeKit and 3D-printed build on this site, real parts, real code, real photos.

Electronics Building a micro-Duck, Part 1: The Plan A small duck-shaped biped that walks with a model trained in simulation, built around an Arduino UNO Q. In this series I build it step by step, explain every word along the way, and show what it costs and what goes wrong. Read the build

Electronics Arduino and the AT-09 Bluetooth LE Module Five Arduino sketches that set up an AT-09 BLE module with AT commands and send the temperature of a DHT22 to a phone. Read the build

Software ESP32 HomeKit Development with ESP-IDF A definitive setup guide for building Apple HomeKit accessories on the ESP32: a Dockerized ESP-IDF toolchain so the build environment stays identical across machines, no local dependency drift, no "works on my machine". Read the build

Electronics Building a micro-Duck, Part 2: The Hardware Every part you need for the XGO-Duck, what it does, and what to check before you order. A shopping list based on the official parts list, with a checklist for when the boxes arrive. Read the build

3D printing 3D Printed Case for a Homebridge Raspberry Pi A black 3D printable case with openings for the network port, USB ports and power connector, for a Raspberry Pi that runs Homebridge. Read the build

Software ESP32 SHT3x Driver for ESP-IDF A driver for Sensirion SHT3x temperature and humidity sensors on the ESP32, packaged as an ESP-IDF component with an I²C example. Read the build

Electronics Temperature and Humidity over MQTT with an ESP-01 An ESP-01 with a DHT11 that publishes temperature and humidity every two seconds over MQTT. Read the build
