harrymcc writes "The Desktop Factory Competition was a contest to create an open-source design for a low-cost machine capable of turning cheap plastic pellets into the filament used by 3D printers, with a prize of $40,000. The winner is being announced today — and he was born during the Hoover administration. I interviewed 83-year-old retiree Hugh Lyman — a proud member of the maker movement — for a story over at TIME.com. From the article: 'Lyman describes himself as an “undergraduate engineer” — he studied engineering from 1948-1953 at the University of Utah, but didn’t earn a degree. Though he holds eight patents, he says he’s “not educated enough to be able to do calculations of torque and so forth.” So implementing his contest entry “was trial and error. I tinkered with it and used common sense.”'"
