Technische Berichte zu dem, was ich baue. Jeder Eintrag behandelt ein Projekt oder Experiment: was ich bauen wollte, den Aufbau, die Experimente, was schiefging, die Messwerte und was ich beim nächsten Mal anders machen würde.
A hackathon write-up: camera-to-robot calibration with AprilTags from 20 poses, grasping with ROS 2 and MoveIt, sorting objects by their height, and the computer vision part that did not make it into the demo.

A native Windows status capsule built with .NET 10 and WinUI 3: a fixed-size transparent window, spring morphs, event-driven providers that read local usage logs, and an idle cost measured in milliseconds.

A hackathon project that records an expert's workflow, asks for the reasoning behind decisions and turns it into a Work Map, with a guided practice mode that catches mistakes before they are saved.

Training a single reinforcement learning policy to swing, catch and hold a double pendulum on a cart in each of its four equilibria, and to switch between them on a keypress.

A fully local voice-and-vision assistant running on an ordinary laptop, with a focus on perception, conversational latency, benchmarking and the engineering failures behind a sub-3-second response target.

Die Projekte, Experimente, Messwerte und Bugs sind meine. Claude hilft mir, aus meinen Notizen lesbare Artikel zu machen. Die technischen Inhalte prüfe ich vor der Veröffentlichung. KI spart mir Schreibzeit, keine Ingenieurszeit.
