Broadly supported C++ open source language and simulation kernel for modeling and implementing electronic systems.

Goals: design an open source hardware, architecture and standard for graphics cards, mainly for open source software and operating systems.

Seeks to design and publish core designs under a license for hardware modelled on the Lesser General Public License (LGPL) for software.

Develops BUG: modular software and hardware platform, web-enabled, set of pre-matched components: color screen, camera (video enabled), GPS, accelerometer; snap together, no soldering. Open source.

Site has a searchable index of many designs, tools and manufacturers.

A collection of links to writings on themes related to Open Source Hardware like definitions, libraries, talks and conferences.

Optical point-to-point data link.

A project working on cameras and imaging solutions with Free software and open hardware. Contains a list of products along with their prices and documentation.

Several open source reference designs, based on 8-bit AVR, ARM7 and ARM9. All schematics and the CAD data are published as open source hardware.

Was "The HULK"; hardware design for a 3D graphics accelerator, written fully in VHDL. Open source.
