Active projects being documented as they happen. Works in progress - warts and all.
An ESP32 controlling six solenoid valves with a phone-friendly web UI, two independent schedules per zone, and automatic fallback to its own hotspot if home WiFi is out of reach.
A thick-case aluminium iMac from Freecycle gets gutted and turned into something useful. The screen works. The brain is an Apple TV.
The factory PCM is 30 years old. Open-source firmware is not. Replacing the brain of a right-hand drive XJ with a Speeduino v0.4.4b and an Arduino Mega 2560.
Two ESP32-CAMs on the roof, one facing east, one west. Both wake at sunrise and sunset, take a photo, and post it to Instagram automatically. No mains power. No manual effort after setup.
A fully wireless weather logger running on solar and battery power. Wakes once a day, takes readings, saves to NVS, serves data over WiFi. No mains power, goes anywhere.
Modding a Thomas the Tank Engine toy, inserting a LiPo, WiFi, and a round TFT, and losing a week to a bad batch of displays.
