Hi everyone, and welcome to ByTechLab!

My name is Andrzej Laczewski — or just Andrew in English.

I’m an electronics engineer and multidisciplinary maker based in Poland. I built this site to document and share the technical projects I work on in my free time — from RF, through analog/digital circuits and embedded software, to mechanical creations and 3D-printed prototypes. Here you’ll find in-depth write-ups, design files, measurements, and lessons learned from real builds.

Feel free to explore the projects, leave comments, or drop me a message if you have questions or feedback!
