Hi!
My name is Andrzej Laczewski (Andrew in English).
I’m an electronics engineer and multidisciplinary maker based in Poland. ByTechLab is my personal space where I document the projects I build in my free time — from RF and wireless systems to 3D-printed mechanical designs, custom PCBs, and everything in between.
What I do:
I love turning ideas into working prototypes that combine multiple disciplines. My main areas of interest include:
- RF Design — antennas, radars, wireless systems, and high-frequency circuits
- Digital Design — microcontrollers, FPGAs, Verilog, and VHDL
- Analog Design — amplifiers, filters, signal conditioning, and precision circuits
- Mechanical Design — 3D printing, CNC machining, laser cutting, and functional enclosures
- Software Development — embedded C/C++, Assembly, Python, and more
- Multidisciplinary Projects — bringing the above together into complete, real-world solutions
ByTechLab:
This website serves as my project log and idea notebook. You’ll find detailed write-ups, design files, measurements, and lessons learned from my builds. The goal is simple: share practical knowledge, inspire fellow makers, and keep pushing my skills forward — one project at a time.
Feel free to explore the projects, read the posts, or reach out if you have questions, feedback, or collaboration ideas. I read every comment and reply whenever possible.
Thanks for visiting ByTechLab — happy making!
