Make: Volume 71, Paperback

Climate change is an urgent threat but if we makers act now, we can still make a difference at both micro and macro levels. Our cover story, the kickoff to a series that will run through 2020, gives a big-picture look at what steps we can take to arrest climate change. Hint: It starts by electrifying everything

Then, we look at some tasty tech with the story of a seriously impressive cheeseburger-making robot, recipes to cook delicious insects, and instructions to build a Raspberry Pi-powered cocktail dispenser for your next BBQ or robot-themed party.

Plus, 21 projects to make, including:

• Hack the Sonos-Ikea Symfonisk to make high-quality, networked bookshelf speakers on a budget
• Build the world's newest, simplest siege weapon, the Walking Arm Trebuchet
• Fold and fly the Guinness World Record paper airplane
• Make a jig for quick, easy, and beautiful box joints
• Our best-yet DIY coffee bean roaster
• And much more
