To overcome the known…


Hardware development has become a hot topic for a wide variety of people. It feels like people with an degree in electrical engineering are actually a minority online communities. There, you find all kinds of people mingling, middle-aged hobbyists, artists, home automation geeks, designers, you name it.

I belong into the software engineering bucket. However, my main expertise couldn’t be further off hardware and low-level programming. For the majority of my professional career, I have been developing interfaces and web services in JavaScript.

Probably that’s where my fascination for learning hardware comes from — finally being able to see behind…
