About Andrzej Laczewski
Creating open-source hardware
Hi, I'm Andrzej Laczewski — or just Andrew in English 😊
I created ByTechLab to document the technical projects I work on in my free time. Whether it's tinkering with electronics, designing mechanical parts, writing code, or combining them all into something interesting, I love sharing the process step by step.
You'll find posts covering:
- Electrical Engineering (analog, digital, and RF)
- Mechanical design
- Software development
- Multidisciplinary projects that mix these areas
Almost every post includes a full GitHub repository with schematics, code, 3D files, and everything else you need to build the project yourself. My goal is to make these ideas accessible so you can learn from them, modify them, or just get inspired.
If my work has helped you, sparked an idea, or saved you some time, I'd really appreciate a coffee (or two)! Your support lets me dedicate more time to creating detailed, open-source content like this.
Thanks for stopping by — happy building! 🚀
