Projects
A handful of things here outgrew the post that started them and turned into something with a repository, a version number and a reason to keep running. These are those, with everything I wrote about them along the way.
FDDB-Exporter
MCP · Spring Boot · MongoDB · InfluxDB Actively maintained
fddb.info keeps a good food database and a usable diary, and then throws the diary away after a while. It also keeps every graph behind the premium tier. FDDB-Exporter pulls your own entries out of it and puts them in a database you control, with a REST API, a web UI and a Grafana-shaped view of what you actually ate.
It started in 2021 as a Python script that scraped a daily calorie total into Postgres. It grew into a Java application with full entry retrieval, then got a Flutter app on top of the same API, later re-released against a rewritten backend. That Flutter app is deprecated now that the backend has gone through a full redesign and got its own UI: a mobile-installable web app, an MCP server so an assistant can answer questions about the diary, and graphs, stats and trends for what you actually ate.
Smart Home Dashboard
Inkplate 10 · ESP32 · Home Assistant · k3s Built and running
A 10" e-ink panel on the wall showing weather, calendar, room temperatures, server load, power draw and internet traffic. It runs on a battery, wakes every 20 minutes to fetch one pre-rendered image from Home Assistant, reports its own voltage over MQTT and goes back to sleep.
I could not find a guide that covered the whole thing end to end, so I wrote one: the hardware and the battery, the architecture, the ESP32 code, the Home Assistant setup, every component on the dashboard, and the k3s cluster behind it. It later ended up featured on Soldered’s Kickstarter campaign for the Inkplate 2.
Smaller tools
The rest of the workshop: small enough that a repository and a line of explanation is the whole story. Several are forks I changed to fit my own setup and left public because someone else had the same problem.
- datadog-api-collector
Pulls host metrics out of the Datadog API and averages them into InfluxDB, so machines in three locations can feed one dashboard without opening a port.
- esp32-dht22-collector
A DHT22 on an ESP32 reading temperature and humidity and publishing them to an MQTT broker, built on platform.io.
- soapui-testrunner-argocd-hook
Resources for an Argo CD PostSync hook that runs a SoapUI suite once a deployment has synced, so an API test suite has somewhere to run in a GitOps pipeline.
- update-time-card
A last-updated card for Home Assistant’s Lovelace, installable through HACS. I needed one for the e-ink dashboard and could not find it, so I rebuilt a clock card into one.
- TelegrafFritzBox
A Telegraf collector for AVM FritzBox routers, forked and dockerized for a cable connection. The upstream version assumed DSL.
- hass-lovelace-screenshotter
Archived on purpose. It rendered a Home Assistant view as a TrueColor JPG the Inkplate could actually display; the upstream project took the changes, so the fork stopped being necessary.
- Qwen3-TTS-streaming-wyoming
A Wyoming server wrapper around Qwen3-TTS so Home Assistant can speak through it. The fork cuts first-chunk latency from 570 ms to 208 ms with a two-phase start, and crossfades chunk boundaries with a Hann window so they stop clicking.
