I am a certified Electronics Engineer who has been working in the field for over 25 years. I was already working with electronics as a child before I made it my profession at a later age. I did my higher education (BEng., Ing.) at Hogeschool Dirksen in Arnhem where I graduated in Embedded Systems.
As a teenager, I messed around with analog electronics and HAM radio’s, building receivers and doing TV repairs to pay for my hobby. After graduation, I worked as a TV repairman but not very long after that, I ended up in my current job as an Electronics Engineer.
Along the way, I wrote a book about designing embedded systems, Embedded Systems Design - The Engineer's Toolbox
During the first pandemic, back in 2020, I looked for ways to keep myself educated and up-to-date in electronics. I learned that ‘The Youtube Academy’ holds a treasure of knowledge for whoever is willing to watch. I found it to be a good reason to start my own channel on Youtube and my first release was a video about an amazing Spectrum Analyzer that was reasonably big in size as it was made with acrylic tiles. During the next two years, I published more video’s about spectrum analyzers and the best part is that all of them are open source.

- Audio spectrum analyzer with acrylic tiles - I built an audio spectrum analyzer along with the housing, PCB, and an increased functionality Arduino Sketch. The original unit is 1m wide and later redesigned to 40cm wide. All my projects are open source with over 100 people replicating this project.
- 64 channel spectrum analyzer - Using the HUB75 displays as a spectrum analyzer that can show from 8 to 64 channels. The challenge is writing the Arduino code and figuring out the FET analysis.
- Twin Audio Visualizer - I found ways to drive 2 displays at a high speed while simultaneously completing FFT analysis. The Teensy controll is used with added external RAM.
