Zero to Maker by David Lang is a book does exactly what it says on the tin. It’s a guide to how to find out how to learn (just enough) to make (just about) anything. I wanted this book so much I helped fund it on Kickstarter.
And now, as we have a copy at Post Tenebras Lab as well, one of the members has been making the OpenROV from this book, which we tested in a swimming pool in Carouge.
