Introduction to
Open Source Hardware
● The Big Picture
– Design, build and market Hardware product is
costly and is traditionally limited to large
cooperation
– With the advent of open source hardware and
software, digital fabrication tools, crowdfunding and
E-marketing platforms – Hardware start-ups is now
within your reach.
