Brief Presentation Have you read the about page? If not, go there NOW 😤! If yes, well… what can I say? I’m Italian, learning every day how to cook something better and better, a passionate book reader, swimmer, and an electronics enthusiast. Like many others, my journey started with Arduino when I was 14, and now here I am, writing in Markdown… what a happy ending, right? But that’s not all. I love chemistry, physics, and biology, as well as classical music. This is why I chose to study electronics after high school, and university has since taken me further than I could have imagined. ...

School/University World Like every student, I’ve studied useful things, and I’m lucky for that. The First WOW! 😮 It all started with Arduino, then moved on to other microcontrollers, but always on hard silicon until I encountered the Microblaze on an FPGA, which opened my eyes to computer architecture. The exciting part for me isn’t just how human-readable code can achieve precise, almost magical outcomes from the outside, but understanding how it all works on the inside. I grew up the day I learned how an operating system works, how the concept of time-sharing made it possible to send people to the moon, and how two hardware devices (a CPU and a timer) use interrupts to switch contexts, enabling many tasks to run “at the same time.” ...

Let’s Begin the Journey Here in Prague, the design center focuses on current sensors, primarily using the Hall effect (mostly) or tunnel magneto-resistance (less commonly). The most important applications of these physical effects are: Hall switch: Used to detect when a current or magnetic field is applied in a particular direction. Magnetic latches: When the magnetic field is on the south pole, it is ON; when it is on the north pole, it is OFF. Linear devices: These provide an output voltage proportional to the input current/magnetic field, usually differential at half-supply of common mode. The image below shows an example of a Hall switch. ...
