This document discusses copyleft hardware, a new movement to create open source hardware designs that can be freely built, modified, and shared. It provides examples of current copyleft hardware projects like the Ben NanoNote pocket computer and SAKC FPGA board. The document advocates designing hardware from the beginning without proprietary tricks or secrets, and releasing plans under a copyleft license like CC-BY-SA to allow others to benefit from and build upon the work. The goal is to bring the positive aspects of forking and community contributions to hardware in the same way free and open source software has benefited from these practices.
