From the project

Open multi-frequency + pulse-induction metal detector: KiCad hardware, search coil, portable-C firmware, iOS/Android apps. Experimental, unbuilt.

An open, simultaneous multi-frequency + pulse-induction metal detector — hardware, search coil and firmware.

MDX-1 is a from-scratch detector design: a KiCad schematic and 4-layer main board, a 2-layer user-interface board, a hand-wound search coil, portable C firmware with a host simulator and test bench, and iOS/Android companion apps. The receive and transmit engine is specified around a coherent, DSP-first architecture:
