A lot of people cite the creative commons licenses for hardware but it’s not really applicable. The license is a copyright license which offers very little protection when it comes to software and no protection when it comes to hardware (normally you have to go the patent route for protection). The original intent of copyrights was to protect authorship and publication rights for books so these protections weren’t ever really envisioned to protect objects like computer hardware. This is alluded to in their FAQ:

Hardware can’t be protected by copyright. Software can be, but it’s easy to circumvent because functionality can’t be copyrighted so, you can basically re-write a code and not be subject to copyright – most likely have to go patent route to do anything. Onloop is only bound by the CC license insofar as it relates to work that is actually copyrightable, like the images or written materials that Vedder published. If it’s just new hardware he’s pushing out it doesn’t really apply unless there’s a patent.
