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.
