I designed this compact laser module for laser projection applications. It is a hybrid design that combines switch mode controller and line driver, allowing for a wide input voltage range without compromising modulation bandwidth.

A collection of side projects, experiments, and fun little ideas. Primarily for my own curiosity, but public on the off chance they might be interesting.
Projects Collection
University group project for closed-loop controlling the beer dispensing process. The fill level is detected using computer vision. The tap, glass tilting angle and gas pressure are controlled using multivariable PID control. A load cell is used to estimate the remaining beer in the keg. The plant can be operated using a react based web app.
Quick'n'dirty tracing and interlacing tool for laser animation. Videos can be loaded and enhanced using OpenCV based python tool. The editor supports drawing splines and linear paths. It keeps track of control points, allowing SLERP between keyframes.
