project Infrastructure stabilization Stabilizing an organization’s technical backbone: administration rules, documentation, a platform for testing and hosting, and a link to the infrastructure one level up. project Investment assistant Local decision support for a personal investment portfolio: broker data, regular reports and an analytical framework with a traceable history of decisions. project mojeWebFoundry A framework for building several separate static sites on SvelteKit. It came out of moving away from Jekyll and doubles as a way to find out what current tooling can do. guide A dumb wireless doorbell in Home Assistant via RF433 and ESP32 How to capture the signal of an ordinary 433 MHz wireless doorbell and send each press to Home Assistant via an ESP32-C3. guide An IR-remote ceiling light via ESP32 and ESPHome How to capture an infrared remote’s codes and control a light from Home Assistant via an ESP32-C3 – without the physical remote. project AI as a tool Turning ideas into working solutions with AI – without a programming background, but with architecture, tests and quality checks as in team development. project Multi-tenant platform A web application for multiple organizations on a shared core: separate data and settings for each client, a modular architecture and security from day one. guide An undocumented display on ESP32: identifying it and getting it running How to get a TFT display without a datasheet working on an ESP32: identify it, wire it up and initialise it. Based on the E32R35T board with an ST7796S controller. guide Czech voice control in Home Assistant: models and custom sentences Czech voice control in Home Assistant: local vs. cloud models (Whisper, Piper, Nabu Casa) and custom sentences for energy and the TV through Hassil intents. troubleshooting Foreign Zigbee devices in ZHA: three cases with custom quirks Three cases of taming Zigbee devices in Home Assistant through a ZHA custom quirk: an mmWave presence sensor, a MOES thermostatic valve and the IKEA SOMRIG button. project A smart home on Home Assistant A household run mostly locally: heating by weather and time of day, electricity and gas metering, custom ESP32 devices and notifications on the phone. link The Grug Brained Developer On humility towards complexity – why simplicity is an engineering discipline, not a lack of ambition. note Podman: containers without a daemon and without root A container tool with no permanently running daemon that can run as an ordinary user and generate systemd units. link openSUSE MicroOS: a system that does not update while running An immutable system with transactional updates on btrfs snapshots, where applications live in containers rather than in the root filesystem. project Infrastructure as Code with Ansible Idempotent infrastructure deployment with Ansible – system and applications, roles driven by host groups, and contributions to an OpenStack deployment. project Cloud platform test automation A framework for automated testing of OpenStack cloud platform updates, storage integration and CI/CD – including a period leading the test team. project A model railway controlled from Kubernetes A model railway fully controlled and monitored from a small Intel NUC computer via Arduino, with the applications running in a Kubernetes cluster. guide A read-only root on Raspbian that survives a cold power-off How to turn Raspbian on an SD card into a read-only root so the device survives being unplugged, and how to turn it into an image for mass deployment. project Read-only Raspberry Pi for daily menu displays Daily menu displays in canteens across the country: a Raspberry Pi that survives being unplugged and deploys without anyone touching it on site. project Packaging for RPM and Debian and the Open Build Service Building packages for both RPM- and Debian-based distributions – spec, dsc and control files, builds locally and in the Open Build Service.
