The president of OSHWA discusses the definition of open source hardware and the six elements required like mechanical designs, schematics, and firmware. She explains how hardware can be designed and distributed openly while respecting trademarks and improving upon designs without copying. The benefits of open source hardware are highlighted for fields like electronics, robotics, and education. Challenges like "fake-duinos" are also mentioned.
