Here is a collection of all the Open Source Hardware projects I've been able to track down In general, a project must have some electronic component and have at least firmware open. Software doesn't count, sorry! "Open source" in this case is strictly defined by the OSI Open Source License definition. Bizarre and/or restrictive licenses don't count.
Items in bold are available for sale to the public either assembled or as kits "Developer only" doesn't count
Projects must be at least started to be counted here!
