Projects
Here you can find links to a few of "my" constructions. All of them live on my GitLab.
Open source – the documentation also includes the Eagle CAD source files, so you can download them and modify or improve them in any way. I will be very happy if you let me know – I will learn something new as well.
PCBs – offer – the documentation contains the manufacturing data for the printed circuit boards, so you can order them from any PCB maker. For most projects I also have spare boards left and can provide them free of charge. We can meet in Prague, you can drop by our radio club in Kobylisy, or I can send them via Zásilkovna (Packeta). Don't hesitate to contact me.
