Open Hardware Repository - Introduction
The Open Hardware Repository ohwr.org is a place on the web for electronics designers at experimental physics facilities to collaborate on open hardware designs, much in the philosophy of the free software movement.
The Manifesto on the ohr-support project wiki page explains the numerous advantages to working in a completely open environment, while on these same ohr-support wiki pages you can find how you can set up your own project. Note that all information on this site is accessible to anyone; you will not be able to access more material by registering.
The CERN Open Hardware Licence (CERN OHL) governs the use, copying, modification and distribution of hardware design documentation, and the manufacture and distribution of products. Other open licence types may be used for projects on the OHR site.
Open Hardware can be commercial
Commercial | Non-commercial | |
Open | Winnning combination. Best of both worlds. | Whole support burden falls on developers. Not scalable. |
Proprietary | Vendor lock-in. | Dedicated non-reusable projects. |

What others write about OHR
- Milkymist: [Milkymist-devel] OHWR - Open Hardware @ CERN (Feb 2011)
- The first CERN Press Release CERN launches Open Hardware initiative in July 2011 gave a large impact. We stopped tracking since this press coverage.
Companies using the OHR site
In December 2012 sixteen companies from eleven countries were actively using the OHR site to develop or produce open hardware, software and drivers. These companies may be paid for the open developments.
Licences used for CERN Open Hardware designs
CERN uses the following licences for most Open Hardware designs:
Hardware
Software and firmware
-
GNU General Public License - GNU
GPL for Software (Python, C,
...)
- Example of use in the OHR project PTS, Production Test Suite
- GNU Lesser General Public License - GNU LGPL for firmware (VHDL, Verilog, ...)
