Moroccan engineer Nawfal Motii has open-sourced the Aeris-10 radar system on GitHub with full schematics and software — the extended 10E variant costs around $7,200 to build and reaches 20 kilometers, compared to commercial phased-array systems that sell for $120,000 to $250,000+. This makes DIY radar feasible for hobbyists and small teams who previously couldn't afford the testing equipment alone ($50k+). Motii is also partnering with Crowd Supply for a Q3 2026 commercial release, though builders should verify local frequency regulations before operating their own units.
