Open Source Licenses

Watch this video for a deeper understanding of the below licenses.

This Wiki has more details on licenses.

These are general guidelines not instructions. The below licenses can be used in many ways on different instruments. Read them to understand how.

For Hardware, CAD files, Schematics, PCB's

• Open Source Hardware use the Logo and provide some kind of license file with it.
• CERN Open Hardware License and follow the instructions.

For Software, Code, Music and Video

• Creative Commons Craft your own license, you choose what attributes you want to have associated with it. It should be noted that only CC-BY and CC-BY-SA are open source licenses in the sense of the original definition at Open Source Initiative -- in particular the NC (non-commercial) and ND (no derivatives) clauses make a license non-open-source.
• GPL Once under GPL derivatives must remain under GPL.
• FreeBSD Once under FreeBSD, derivative licences can be changed.

Public Domain

• You can enter something into the Public Domain by providing a legal statement with it that states so. Once in the Public Domain it will remain there permanently. This procedure will vary from country to country. I would recommend asking for advice from a lawyer, notary public or solicitor. You should be able to get free advice on how to do this procedure. Actually doing the procedure might cost.
