<p>The TAPR OHL was developed by Tucson Amateur Packet Radio, and like the CERN OHL was created to extend the success of OSS licenses*. It is available for anyone to use, and can be downloaded directly from their website [1]. Just like the CERN OHL it is a Copyleft or ‘viral’ license: the terms applied to one product are propagated to all downstream products. In short, this means that once a product is made open-source, it and all it’s modifications remain accessible to the community.</p> | <p>The TAPR OHL was developed by Tucson Amateur Packet Radio, and like the CERN OHL was created to extend the success of OSS licenses*.

− | <h2> Open Source Hardware </h2> | + | <h2>Open Source Hardware</h2> |
<p>The Cambridge-JIC team is looking to make our product as accessible as possible. This means making our microscope open-source. According to the Open-Source Hardware Association (OSHWA), this means it “is hardware whose design is made publicly available so that anyone can study, modify, distribute, make, and sell the design or hardware based on that design” [1]. This not only requires well-documented procedures but also clear and simple designs that can be modified by non-experts.</p> | <p>The Cambridge-JIC team is looking to make our product as accessible as possible.

The names in the boxes represent common licenses, and the ‘+’ means ‘and all later versions’. David Wheeler created this graph in the context of OSS, but some of the licenses are applicable to hardware. For a clarification of some of the terms, see the glossary.</p> | ||
