Make: magazine, Volume 11 (PDF)  includes a special "DIY Wheels" section, with plans for making a mobile drive-in movie theater, a cool chopper out of an old bicycle, and a pedal powered iPod charger. We'll also show you how to make a remote control bird feeder to take amazing photos of birds, a vintage- style remote control race car out of sheet-metal, and a vacuum-former that lets you create molded 3D parts out of plastic.
