Erwin Damsma
By day I'm lead developer at TRES, a digital agency in Heerenveen, building web platforms for clients.
On the side I build small, focused tools.
Side projects — 5 nodes
- wallbox-modbus github.com/erwindamsma → Dynamic load management for a Wallbox Pulsar Plus without the Power Boost accessory: emulates the energy meter it expects on RS485, fed with live grid power from Home Assistant.
- lidl-receipts-analyser github.com/erwindamsma → Fetches your Lidl Plus receipts with every line item, stores them in SQLite and analyses them offline. No dependencies, just the Python standard library.
- RALscope ralscope.damsma.dev → Identify RAL paint colours from a photo. Upload an image, set a reference point with a known RAL colour, then identify any other colour in the shot.
- Vesso vesso.nl → The facts behind any Dutch number plate. APK status and defects, inspection history, technical data and open recalls, straight from open data in your own browser.
- Simmer simmer.damsma.dev → A personal recipe box. Paste an Instagram reel or recipe blog link, check the extracted recipe, save it. Search, group into collections and sync across devices.
