This might be the most dangerous GitHub repo ever published.
Someone built a full 10.5 GHz radar system that can track targets up to 20km away and open sourced the entire thing.
It ships with:
→ Complete PCB designs and schematics
→ FPGA signal processing code
→ STM32 firmware
→ Python GUI with map integration
→ GPS/IMU integration
→ MIT license (100% free)
6.8k stars on GitHub already
This is the kind of project defense contractors would charge you a fortune for.
One dev just put it on GitHub.

A mini OCFD hybrid balun for POTA. This is the best one I've ever made. Fantastic Nano sweep on 200Ω resistor 💫 Type 61 for transformer & type 31 for the current choke. I'm going to spray it with clear FlexSeal at some point. @TheSmokinApe
