This is an old revision of the document!
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.
Projects must be at least started to be counted here!
Cores (Chip designs)
a replacement control board for standard robotics servos
Open firmware/software general purpose sequencer
Open "Set-top" Digital Audio Player
Open source monophonic MIDI synthesizer (one of my projects)
Pedagogical physical-computing platform
Open source linux/wifi/sensors device, available retail for $200
Projects that are NOT open hardware
