Projects

, the side projects that wouldn't leave me alone. Small things, mostly. Useful enough to keep around.

Project
The energieprijs.info landing page with a daily energy price digest signup and an email preview showing hourly prices as a bar chart.
energieprijs.info

A small Dutch tool for people with dynamic energy contracts: daily prices, cheap and expensive hours, and a digest in your inbox so you can plan the dishwasher, dryer or EV charger before the peak hits.

The p1meter.dev interface: a skeuomorphic smart meter with a CRT-green display reading 001235.267 kWh, tariff lights, a physical cycle button and a P1 port type plate.
p1meter.dev

A virtual Dutch smart meter you can talk to over plain TCP, or leave open in a tab and watch tick. It's my DSMR parser running backwards inside a skeuomorphic Phoenix LiveView, sending a checksum-perfect telegram every second.

The quario landing page, headlined "Agents draft the pages. quario does the folding.", next to an agent transcript that validates a report, fixes two problems and renders Invoice No. 1042.
getquario.com

Reports as data instead of code. A model or a person drafts a JSON definition, quario computes every total from your data and renders it as HTML, a paginated PDF, an Excel workbook or Word, with no headless browser and nothing the model wrote ever running.

A Heuvelradar loop on the tilted relief map: a 680 m lap over a landfill hill in Zoetermeer, marked from NAP −5 m to NAP +14 m.
heuvelradar.nl

Hill training in a flat country. Pick a start and a climb target, and it finds short, steep running loops nearby on half-metre Dutch elevation data and OpenStreetMap paths, then works out how many laps get you there. A Phoenix app with the search in Rust, loaded as NIFs.
