Maker Education is such a valuable role. These stories will bring you the latest information and tales of maker educators who area spreading the maker mindset. Help others learn how to make things or how to think like a maker at makerspaces, schools, universities, and local communities. The importance of maker education can not be understated. We appreciate our educators.
Bill Hammack’s video confection is especially sweet this week. Bill scored a vintage Delta “black box” on eBay and, in this week’s installment, tears it apart on camera to show you how they built ’em in the old days to stand up to “three-thousand gees and one-thousand degrees.” I just watched it, and I’m having a hard time resisting my ebullient urge to spoil the ending for you, so I’ll just shut up and let Engineer Guy take it away. [Thanks, Bill!]
An inverting or tippe top is a classic physics toy: a spinning top that spontaneously inverts itself to spin on its handle at high speed, then rolls back over onto its base when it stops. Turns out, four spheres joined in a close-packed tetrahedron will do the same thing, and this quick video tutorial from YouTuber VTK9990 shows one made from four marbles and some epoxy.

And you can watch it happen in this literally awesome video from the BBC’s Bang Goes the Theory. I wonder how much that lens cost? I’ve got a shed out back, wouldn’t be too hard to cut a hole in the roof… [via Boing Boing]
A month ago, I blogged about Ron Doerfler’s beautiful Age of Graphical Computing calendar for 2010, lamenting the fact that it’d only appeared on my radar at the end of the year. Well, I’ve been keeping an eye peeled, and Ron just released his 2011 calendar. It’s not about graphical computing, but about what is perhaps an equally interesting mathematical curiosity: Techniques for doing fast mental math. And it looks to be just as beautiful.
When I was in graduate school, I took a seminar class from a chemist whose work in developing self-healing polymers was widely admired. I had seen these self-healing cutting mats in the MicroMark catalog, and always wondered what they were made of. So I asked him, in class. He looked at me like I’d grown a second head: “You mean to tell me you’ve seen self-healing polymers on the market? In a consumer product?” Later I brought him the catalog, and showed him the listing. He was stumped, and more than a bit dubious.
They just put up a great article about the machines people used to lift and move heavy loads before the advent of steam power. Arguably the pinnacle of human-powered lifting technology were Sir William Fairbairn’s hand-cranked “Tubular Cranes,” one of which is shown above as illustrated in Fairbairn’s 1860 Useful Information for Engineers, Vol. 2:
If you’ve been around long enough to have ever actually blown out your flip-flop, stepped on a pop top, you’ve already got one great reason to appreciate the 1975 introduction of the stay-on tab or stay tab: No more little metal razors littering the beaches.
Now, “Engineer Guy” Bill Hammack helps us appreciate the stay tab for another reason: It’s a little gem of mechanical poetry. There’s a lot going on when you pull that little ring. Bill’s video exegesis of that action, like all Bill’s videos, is a little piece of poetry unto itself. I can’t get enough of ’em. [Thanks, Bill!]
