I made a simple HAT (Hardware Attached on Top) for the Raspberry Pi to read multiple DS18B20 temperature sensors — it was surprisingly easy. I used the measured temperatures to control a fan using Home Assistant.

My twin boys are, like their dad, fascinated by switches and flashing lights. I needed an excuse to use the Raspberry Pi Zero in a project, so I built them a WiFi MQTT controlled alarm module. With a couple of switches, some panel indicators, a buzzer, and a blue LED strobe.

Dropping the Altibox router/modem, and getting IPv6 using 6rd to work on OPNsense.

I’ve been hosting repository mirrors from my homelab rack for a while. I first set up Archlinux in May 2018, then followed OPNsense, Cygwin, MariaDB, Raspbian and lastly Manjaro — now they are in a Terrahost datacenter instead.

I rebuilt the exhaust ventilation late 2017, but shortly after — I did the homelab ventilation project and had to remove parts of the exhaust system because it was in the way of the new insulated ducts. Time to rebuilt it!
