I have the Dremel tool drum sander mandrel on the left. I don't think the design has changed since 1962, and it sucks mightily. Sanding drums get stuck on it and new ones don't fit on it (at least not for me). I just read Stuart Deutsch's post on Make about the EZ Drum Sanding Mandrel, which sounds like a game-changing improvement on the black rubber mandrel.
Dremel has introduced a couple of new “EZ Lock” rotary tool accessories in recent years that allow for tool-free bit/disc/pad changes. The newest EZ-change addition, a sanding mandrel, has quickly become one of my favorites. With the old-style sanding mandrel, you must toil with a small screw before and after swapping in a fresh sanding sleeve, but with this one you just push and pull.
I have been quite pleased with the direction Dremel has been headed. They dominate the rotary tool and accessories market, so they don’t really need to upgrade little things like mandrels, but they have been doing it anyways. Recent models, such as the 3000 and updated 4000 series rotary tools, feature a built-on collet wrench, and it looks like the upcoming Dremel 4200 will feature a new completely tool-free collet-lock mechanism.

Etsy seller Timothy "Cthuluforyou" Kostelnik sells a wide variety of tentacle- and eyeball-themed housewares, but few match his $38 mutantini glass for sheer encrustation with pseudopods, viscera and staring, disembodied eyes; it makes a hell of a sludgabilly accessory. (via Creepbay)
CNLohr discovered that underclocking the ESP8266 wifi module's Baseband PLL made the wifi channel progressively narrower, until it could not longer be detected by an unmodified wifi receiver -- but a similarly modified wifi module can detect the narrow signal, creating a s00p3r s33kr1t wifi channel; here's sourcecode (which may violate FCC Part 15 rules, […]
