Building a mmWave material classification radar: A hardware startup journey
By
GL26
Summary
A detailed first-person account of building a millimeter-wave radar system for material classification (specifically asbestos detection) as an end-of-studies project turned hardware startup attempt. The author describes the technical journey of designing the radar hardware, signal processing pipeline, and beamforming algorithms, while candidly discussing the challenges of hardware entrepreneurship in Europe, including funding difficulties that ultimately led to the project stalling. The piece blends technical depth with raw reflections on startup struggles.

· 4 pulledSoftware is now a commodity thanks to Claude Code. So the next step is obviously hardware.
I spent the last 6 months on building a hardware startup, which was fucking hard.
I live in Europe, where asbestos is a huge and common pain across every country
The project never ended (as you will see down this article, because of a lack of funding)
