Hacktivists share a guide on making working electronics PCBs from natural clay using a prehistoric technique — an ethical hardware tutorial explains how to find clay, stamp 3D-printed circuits, paint traces, and fire tablets

Feminist Hacking published an open-source guide for making working PCBs from locally sourced clay.

The process uses a 3D-printed stamp, conductive silver paint, drying, and firing in a kiln or open wood fire.

The project highlights a low-tech alternative for prototype boards that reduces reliance on conventional PCB supply chains and mined inputs.
