    About Open Hardware Observatory OHO e.V.

    OHO e.V.: The non-profit association Open Hardware Observatory e.V. (OHO) was founded in 2020 as a Spin-Off of the Technical University Berlin. Our goal is to promote technologies for sustainable development and to make the blueprints available to everyone as open source projects.
    Our work areas are project research and project selection, standardization of technical documentation, quality testing and certification of projects, and making them as widely known as possible. Our vision is to create a "Wikipedia for Sustainable Technologies" that enables people, organizations and companies from all over the world to make our planet more sustainable.

    Free Blueprints and Videos of Sustainable Technologies

    • More than 95% of all Do it Yourself or Open Hardware projects are incomplete or not documented at all.
    • So they cannot be rebuilt by other people o companies (or only with great difficulty).
    • OHO has developed a simple and practical standard for the technical documentation of Open Hardware projects.
    • OHO selects particularly good projects and creates the necessary CAD files, drawings, parts lists, etc.
    • All created documents are published under the license CC-BY-Sa 4.0.
    • This means that everyone can use them, modify and develop them and also use them commercially.
    • The OHO CAD Center with its qualified engineers is available for all Open Hardware developers.

    OHO Certification Center

    • Until recently, there were no technical standards for Open Hardware.
    • In 2020, we developed the world's first standard for Open Hardware together with the German Institute for Standardization (DIN) and other organizations.
    • This standard uses a community-based peer review process that is often used for scientific publications.
    • OHO is the first platform on which this procedure is applied.
    • The aim of the Certification Center is to guarantee that projects published on OHO meet international quality criteria.

    OHO Search Engine

    • Many good Open Hardware Projects are unknown and difficult to find in the web.
    • The multilingual OHO Search Engine aims to show as many projects as possible on a common platform.
    • The Search Engine crawls the whole web and selects relevant search results according to different algorithms and categorizes them.
    • The Search Engine has a keyword search, a professional search and a category search.
