Only something that’s transformed before use can be “open source”. (duh)

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● ….

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

Open Source Hardware around the World
Mostly EU/US thing?
China: every hardware is “open” sourceshanzhai 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
