The document summarizes a presentation given by Gabriella Levine, President of the Open Source Hardware Association (OSHWA), at the Open Hardware Summit 2014 in Rome, Italy. The presentation defined open source hardware as designs that are publicly shared so anyone can study, modify, distribute, make, and sell the design or hardware. It provided examples of open source hardware projects in various fields and discussed best practices for sharing and licensing open hardware designs to ensure they remain open for others to build upon and improve.
