I study Computer Science & Engineering at TU/e, but I spend most of my time on power electronics and PCB design. It started with a half-bridge that barely worked and I've been hooked since.
Right now I'm building a bidirectional current source for magnet testing — full H-bridge, hardware overcurrent protection, the whole thing designed from schematic to board. It's the kind of project where you learn something new every time you turn on the bench supply. I like problems where the datasheet doesn't quite tell you everything.
Outside of that I'm an upcoming student at CERN Summer Student Programme, electrical engineer at Polar Student Team, a tutor, and I run sometimes.
