MAKE 14: Optics

Keep an eye out for MAKE Volume 14, with a special section on optics. You'll learn how to make an inexpensive but powerful digital microscope that can display bacteria colonies on a video monitor, a vintage-looking opaque projector that can display artwork onto a wall, a model of a crazy-angled Ames room that makes things appear to change size, and a cool kaleidoscope. Also, we'll show you how to build a mesmerizing taffy pulling machine, a remote control dune buggy with a built-in telepresence video camera, a dollar-store parabolic microphone, retro music visualizer, and many more fun and fascinating projects.
