Instead of making something new -- support the guys at Denhac - the Denver Hacker Space. Good folks - some of them a bit touched - but good folks none the less. They routinely do classes on all sorts of fun stuff. They have all sorts of goodies like lasers, 3d printers, a 5 ton glass cutting table, etc.
