Only something that’ s transformed before use can be “open source”. (duh)
Some Notable Open Source Hardware Projects
Arduino Check Eagle for source code!
RepRap 3D printer
Olimex
BeagleBone Black

Thinking behind OSHW
Why to do open source hardware? ● User trust, mindshare ● Community support ● Getting good developers ● Building an ecosystem ● Maintainability, sustainability ● ….
Why NOT to do open source hardware? ● Protecting IP ● Hiding imperfections in design ● Not caring or not know about the possibility ● Not liking to be held to a high standard ● ….
The tools and ecosystem
Open Tools (some) Electronics: KiCad http://kicad-pcb.org/ Mechanical: FreeCAD http://www.freecadweb.org/ OpenSCAD http://www.openscad.org/
Project Sharing ● Hackster.io https://www.hackster.io/ ● Hackaday.io http://hackaday.io/ ● Seeed Studio Recipe http://www. seeedstudio.com/recipe/ ● Thingiverse http://www.thingiverse.com/
PCB / Electronics Making ● OSH Park http://oshpark.com/ ● Seeed Studio FusionPCB http://www. seeedstudio.com/service/index.php?r=pcb ● Dirt Cheap PCBs http://dirtypcbs.com/ ● Circuithub https://circuithub.com/ ● Marcofab http://macrofb.net/

Some practicalities
Licenses to Consider Creative Commons (CC-BY) https://creativecommons.org/licenses/ CERN Open Hardware License http://www.ohwr.org/projects/cernohl/wiki …
A Usual Development Process ● Put all code in version control, e.g git ● Bill of Materials (BOM) ● Create Plenty of Documentation ○ Hackpad, Wiki, nice PDF… ● Start building a project community
Q&A
Open Source Hardware around the World Mostly EU/US thing? China: every hardware is “open” source shanzhai spirit 山寨 Spreading with the maker movement
How to contribute if not technical? ● Feedback, lots of feedback ● Contribute design ● Use, learn, develop ● Do other creative projects to create culture of openness
