With the aim of dissemination and knowledge sharing to the society, the Particle Physics Engineering group within the technology transfer activies has created the CIEMAT Open Hardware License site (CIEMAT-OHL) through which we publish some of the hardware designs made by our team in the spirit of sharing them openly with the society. The goal is that this designs, in case they are useful beyond our team, could be used by anyone.

The conditions of use for the public designs can be seen below. This conditions governs the use, copying, modification and distribution of hardware design documentation, and the manufacture and distribution of products. Anyone downloading or using these designs should have accepted them.

CIEMAT-OHL intends to be to hardware similar to what the General Public Licence (GPL) is to software, with similar conditions under which a licensee will be able to use or modify the licensed material. The concept of ‘open-source hardware’ or ‘open hardware’ is not yet as well known or widespread as the free software or open-source software concept. However, it shares the same principles: anyone should be able to see the source (the design documentation in case of hardware), study it, modify it and share it. In this way, we ensure that the whole community will continue benefiting from the work developed at our center, reverting our work in the benefit of the society.
