Open Source Platforms for Wearables

Gene Leybzon, June 2015

Open Source Hardware Movement

Machines, devices, or other physical things -- whose design has been released to the public in such a way that anyone can make, modify, distribute, and use.

Examples of Open Hardware

Prototype faster Affordable cost of

hardware Leverage community Reduce risk Use existing code
