Welcome to the Open Hardware Repository
A easy-to-browse catalogue of open hardware designs used in experimental physics facilities, with links to the designs themselves and to forums where you can discuss about them.
About OHWR
The Open Hardware Repository ohwr.org is a place on the web which was created in 2009 so electronics designers at experimental physics facilities could have a space to collaborate on Open Source Hardware (OSHW) designs, much in the philosophy of the free software movement.

White Rabbit
Job vacancy at CERN to work on White Rabbit and RF
We have an open position at CERN to work for 2-3 years on the evolution of the eRTM board. It is a WR node whose jitter (integrated between 100Hz and 20MHz) is less than 100 femtoseconds, the most precise WR node I know of, originally designed by Mattia Rizzi and Tomasz Włostowski.
