Welcome to my homepage. This is where I show my small ideas and experiments, which grow further whenever there is a reason to. Have fun exploring.

Everything here is built to collect as little data as possible, and works largely offline in the browser.

Webapps

Waye

Live audio spectrum from your microphone: waterfall display, multi-FFT, peak frequency, note detection and a guitar tuner. Runs right in your browser. The name: wave + eye = Waye.

Webapp

Das Licht

Live sun position: 3D space view of Earth, shadow cast and sun phases.

Webapp

CamStack

Camera tools straight in the browser: make movement, edges and what stays behind visible, plus LightPaint. The image stays local — nothing is uploaded.

Webapp

Lap counter

Counting laps at a sports day: by hand via keyboard and tiles, or by camera reading QR race numbers. Phones can join as extra cameras. Race numbers and certificates come out of the same page.

Webapp

Sudoku

Five difficulty levels, honestly graded: not by the number of givens, but by how much work and which solving technique a puzzle really demands. With notes, checking and hints — and playable by two.
