Good day! For a while, I worked on creating completely open hardware solutions (such as Antenna Mini-Whip, HF Upconverter, and etc.) used to expand capabilities and work with low-cost SDR receivers (RTL2832U). At the moment, all devices publicly available on GitHub. You can get acquainted with it and maybe find something interesting for yourself :)
In this project, I focused on the simplicity of self-assembly devices, which you can make at home. In the repository, you can find detailed assembly instructions, a list of necessary components for assembly, and Gerber files. I try to actively support the project, correct the errors found and add something new.
