Earlier this month EE Design posted an article on Open-Source Hardware by Jamil I Khatib and Mohamed A. Salem of the Arab open source organization, Handasa Arabia. The article explains the similarities of open hardware to Free/Open software. Like Open Source software, open hardware has the potential to greatly benefit the developing parts of the world, leveling the playing field by making high quality products available with the high licensing fees and restrictive sharing policies typical of proprietary products. Readers are referred to sites like Open Collector, gEDA and OpenCores for tools and more information. Robot builders can find quite a few interesting items in the currently available pool of open hardware.
