cultural and educational. Does open design and open-source hardware design process involves new design practices, or raises requirements for new tools? is the question of openness really key in OSH?. See here for a delineation of these terms. A major contributor to the production of open-source hardware product designs is the scientific community. There has been considerable work to produce open-source hardware for scientific hardware using a combination of open-source electronics and 3-D printing. Other sources of open-source hardware production are vendors of chips and other electronic components sponsoring contests with the provision that the participants and winners must share their designs. Circuit Cellar magazine organizes some of these contests. Open-source labs A guide has been published (Open-Source Lab (book) by Joshua Pearce) on using open-source electronics and 3D printing to make open-source labs. Today, scientists are creating many such labs. Examples include: Boston Open Source Science Laboratory, Somerville, Massachusetts BYU Open Source Lab, Brigham Young University Michigan Tech National Tsing Hua University OSU Open Source Lab, Oregon State University Open Source Research Lab, University of Texas at El Paso Business models Open hardware companies are experimenting with business models. For example, littleBits implements open-source business models by making available the circuit designs in each electronics module, in accordance with the CERN Open Hardware License Version 1.2. Another example is Arduino, which registered its name as a trademark; others may manufacture products from Arduino designs but cannot call the products Arduino products. There are many applicable business models for implementing some open-source hardware even in traditional firms. For example, to accelerate development and technical innovation, the photovoltaic industry has experimented with partnerships, franchises, secondary supplier and completely open-source models. Recently, many open-source hardware projects have been funded via crowdfunding on platforms such as Indiegogo, Kickstarter, or Crowd Supply. Reception and impact Richard Stallman, the founder of the free software movement, was in 1999 skeptical on the idea and relevance of free hardware (his terminology for what is now known as open-source hardware). In a 2015 article in Wired Magazine, he modified this attitude; he acknowledged the importance of free hardware, he still saw no ethical parallel with free software. Also, Stallman prefers the term free hardware design over open source hardware, a request which is consistent with his earlier rejection of the term open source software (see also Alternative terms for free software).
