Open Hardware Observatory
From OHO - search engine for sustainable open hardware projects
OHO Open Hardware Observatory
- www.oho.wiki (OHO) is a web platform that supports, improves and makes known Sustainable Open Hardware Projects.
- Open Hardware are machines or other products whose blueprints can be freely used and improved.
- OHO was founded with the support of the Technical University of Berlin.
- OHO consists of the CAD Center, Certification Center and Search Engine.
- OHO cooperates closely with Wikipedia and other free knowledge organizations.
OHO CAD Center
- 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.
