For the last couple of years there has been a resurgence in popularity of vinyl records. In this short documentary from Nick Cavalier we get a behind-the-scenes look at the production of vinyl records at Gotta Groove Records, a new vinyl pressing plant in Cleveland, Ohio.
Recently, I had a class of 7th graders designing in Sketchup. One of the projects is to accurately design a block of 2″ x 2″ x 1.25″. These designs were then converted to G code with Millwizard by an 11th grader who then milled them in the high school across the street on a Taig Micromill. This was a fun project that helped illustrate the concepts and processes of separating the design from the manufacture of objects.
The way it worked out was that the middle schoolers would make some designs, and share them with the high schooler. If the files were designed correctly, proper size, no overhangs, then they would be converted to code and milled. He was able to process 4 files in one class period by cutting in 2 inch insulating foam. Then, the next time I met with the 7th graders, I gave them the blocks they designed.
These industrial robots move at inhuman speed while deftly maneuvering in unison and maintaining a sub millimeter tolerance.
Tiny metal spheres are needed for tiny ball valves and tiny ball bearings, which are needed for all kinds of miniaturized machines. Hollow spheres are lighter, and thus have less inertia, and thus can be made to move faster in these very small applications, where response time is often critical. But how do you make a hollow metal sphere 2mm across? Turns out you can do it with one of the lost foam processes I’m always going on about. Tiny styrofoam beads are first coated with fine metal powder and a binder, then heat-treated to evaporate both binder and bead, leaving only a fragile hollow metal powder shell, which is then sintered into a continuous shell at higher temperature. The sintered shells can then be polished in a tumbler to the same exterior finish as regular ball bearings.
Rodney Brooks, of MIT’s AI Lab and iRobot, is one of my all-time heroes. His work has had a huge impact on how I look at technology in general, robotics in specific, approaches to problem-solving, and more. So I was bummed that I missed his talk (and meeting him) at Maker Faire. Thanks to FORA.tv, […]
[Image from Inventaholic] Perry Kaye is a great inventor I met at Maker Faire Austin in 2007. Recently, we have had several conversations about the process for bringing a product to market. He has set up a site around the idea of inventing for regular people. Invention is not always about money. For many of […]
