In this video, Matt Richardson shows you how, based on a tutorial from MIT Media Lab’s High-Low Tech Group.

MAKE Flickr Pool Weekly Roundup

MAKE Flickr Pool Weekly Roundup

Other highlights include a beautifully printed and photographed mechanical differential, some 2-liter bottlecaps modified for a home carbonation system, and a brain in a jar. Mmmmmm. Brains in jars.
