Information About

Open Source Hardware




Open source hardware refers to computer and electronic hardware that is designed in the same fashion as Free and Open-source Software . Open source hardware is part of the Open Source Culture that takes the open source ideas to fields other than software. An example of this is the Simputer project.

Some of the impetus for the development of open source hardware was initiated in 2002 through the Challenge To Silicon Valley issued by Kofi Annan {Link without Title} . Because the nature of hardware is different than software, and because the concept of open source hardware is relatively new, no exact definition of open source hardware has emerged.

Because hardware has direct variable costs associated with it, no open source software definition can directly be applied without modification. Instead, the term open source hardware has primarily been used to reflect the use of free/open source software with the hardware and the free release of Information regarding the hardware, often including the release of schematics, design, sizes and other information about the hardware. In anyway, it includes the hardware design and element distribution on the motherboard (i.e. a Notebook where one can replace elements).

With the rise of reconfigurable Logic Device s, the sharing of logic designs is also a form of open source hardware. Instead of sharing the schematics, HDL code is shared. This is different from free/open source software. HDL descriptions are commonly used to set up SoC systems either in FPGA s or directly in ASIC designs. HDL modules, when distributed, are called Semiconductor Intellectual Property Core s, or IP cores.

Organisations

  • Open Hardware ('''OH''') is a project in which Hardware Design ers share their work by disclosing the Schematic s and Software ( Driver s) used in their designs. Open hardware Designers meet, discuss what they are doing and ask each other for assistance in finding parts, or seek ideas to solve design problems. OH is also an opportunity to exhibit designs, so some may learn from what others have done.

  • OpenCores is a Foundation that attempts to form a community of designers to support open-source cores (logic designs) for CPUs, peripherals and other devices. OpenCores maintains an open-source on-chip interconnection bus specification called Wishbone .
