This post continues my coverage of the Fourth Oekonux Conference. Johan Söderberg talked about the Czech open hardware project Ronja. RONJA was developed to provide a cheap, easily producible alternative to Wi-Fi, allowing wireless data transmission between computers. Amazingly, Ronjas use visible light for data transmission, but they are quite fast (10 MBit/s) and allow reliable point-to-point data transmissions, except in case of fog.
The goal of the Ronja project was not only to build affordable open hardware for data transmission, but also to allow the creation of anonymous, censorship-proof networks that can’t be controlled by companies or the state. All design information has been published under the GNU Free Documentation License. The Ronja hardware was sufficiently successful to be employed not only by private people, but also by companies.
