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 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
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
Winning combination. Best of both worlds.
Whole support burden falls on developers. Not scalable.
There are eleven instititutes leading the different projects: CERN,
Soleil, GSI, Brazillian Light Source, University of Bristol, Warsaw
University of Technology, University of Zurich, University of Pavia,
Rockefeller University, University of Cape Town, Heidelberg
And there are 16 commercial companies are
involved who develop, produce and/or
test open hardware products.
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. Actually
in July 2014 the number is the same.
Note: we think that there is curently no perfect copyleft
license for gateware. We are trying to contribute to remedy that
situation. See Document. In the meantime we are using LGPL
as many other people do, including many projects in
opencores.org. We are also, for some cases where we need to be
more formal, temporarily switched to the
Solderpad 2.0 license
(a permissive, i.e. non-copyleft license) while we work on CERN
OHL v2, which should provide a reliable licensing solution for
projects which need either strong or weak copyleft.
