Join today’s new revolution in creativity and community: hackerspaces. Stop letting other people build everything for you: Do it yourself. Explore, grab the tools, get hands-on, get dirty…and create things you never imagined you could. Hack This is your glorious, full-color passport to the world of hackerspaces: your invitation to share knowledge, master tools, work together, build amazing stuff-and have a flat-out blast doing it. Twin Cities Maker co-founder John Baichtal explains it all: what hackerspaces are, how they work, who runs them, what they’re building-and how you can join (or start!) one. Next, he walks you through 24 of today’s best hackerspace projects…everything from robotic grilled-cheese sandwich-makers to devices that make music with zaps of electricity. Every project’s packed with color photos, explanations, lists of resources and tools, and instructions for getting started on your own similar project so you can DIY!
