MAKE 26: Karts and Wheels

Roll into spring with MAKE Volume 26: "Karts and Wheels"

Garage go-kart building is a time-honored hobby for do-it-yourselfers, and we’ll help you build wheeled wonders that’ll have you and the kids racing around the neighborhood in DIY style. Build a longboard skateboard by bending plywood. Propel a go-kart with a pair of battery-powered drills. Put a mini gasoline engine on a bicycle. And construct an amazing wind-powered cart that can outrun a tailwind. Plus, learn how to build the winning vehicle from our online Karts and Wheels contest — a full-custom adult Soapbox Derby racer!

In addition to karts, you’ll find plenty of other projects that only MAKE could give you:
• A flaming tube that keeps time to music and makes sounds waves visible — in fire
• An easy, fun synthesizer and loop station for making electronic music
• A fun reflex game called Pendulum Challenge (Buy the kit in the Maker Shed!)
• Two bio-sensing projects: a lie detector and a controller driven by your brain waves (Buy the lie detector kit in the Maker Shed!)

All these projects and much, much more await you in MAKE Volume 26!
