Mario Marchese of Nyack, NY, built this neat drawing machine: This is “The Audio Portrait Artist (TAPA).” It is made from recycled DC motors, cigar boxes, pieces from a broken multimeter, roof shingles, wine corks, and old radio knobs. TAPA works similar to a CNC machine, but instead of cutting things, it draws. There are […]
Owen sent a link to his very sweet CNC laser that can cut sheet metal. He’s spent over two years and $15K developing the system. This is a CO2 laser system that cuts sheet metal. The laser and all optics are stationary. The beam is directed downwards on to the part that sits on a […]
Awesome party toy for dirt cheap, provided you’ve got the necessary outdoor space (and the, ah, secure 40-foot overhang). Made from used tires, wooden poles, and “a whole lot of metal bolts and cables” by Jan Köaut;rbes, these swings are suspended from the superstructure of the Mmabatho Sports Stadium in South Africa.

Inspired by the amazing characteristics of perfluorocarbon, Dave over at Mechanical Mashup decided to build a DIY dive light by submerging a cheapo LED flashlight from the hardware store in mineral laxative to achieve neutral pressure within the enclosure.
Be your kid’s hero by helping him/her build a pony/unicorn from scrap plywood. A sweet story from Sweet Juniper: When I asked her what she wanted to make for our project last week, she hadn’t had a horse lesson for a month because her instructor was traveling to various horse shows out west. She told […]

Everything’s held together with grub-screws. Runs off two AAA batteries which just fit inside.
Stereoscopes and View-Masters have always fascinated me. The technology has been around for over a century and seems to have been reinvented with every generation. If you’re thinking about getting into shooting 3D, but would like to keep the costs down, you’ll want to check out this 3D Stereoscope Slide and Video Shooter Instructable by courtervideo.
