Building OSH: DIY Manufacturing for Hackers and Makers
This hands-on guide from Alicia Gibb gives an incredible run down of the world of open source hardware from history, to meaning, to practice. The first part of Building Open Source Hardware focuses primarily on the emergence and evolution of open source and what the term means - both by definition and in practice.
In the second half, Building Open Source Hardware draws on industry leaders to share proven approaches to various elements of the open source hardware process - from design to documentation - and then dives into hands-on learning and experimentation.
It's a wonderful beginners' guide to joining the burgeoning open source movement or a great overview for anyone who's interested, passionate, or obsessed with OSH!
