So I don’t want to go too far down the “funny warning signs” rabbit hole (you could get a whole blog out of that, I think), but a commenter on last Tuesday’s “Big Scary Laser” warning sign post linked to this design, of hers, for a warning sign to go on robotic power tools. I get a huge kick out of the giant menacing robot with the buzz-saw hand. [Thanks, Jennifer!]
A so-called “stick bomb,” “frame bomb,” or (worst of all) “xyloexplosive device” (Wikipedia) is an arrangement of flat flexible beams, like popsicle sticks or tongue depressors, that are woven together under tension such that they can be “set off” at one point and sort of explosively disassemble starting at that point, with the reaction propagating away along the structure. Like domino toppling, but flashier.
On Wednesday morning, Evan Ackerman over at BotJunkie posted about MIT’s Flyfire system. The idea behind the system is simple and very exciting: Swarms of tiny LED-carrying robot helicopters arrange themselves in the air to make 2D or 3D displays in which each bot serves as a single pixel. Evan linked to the project’s homepage on MIT’s SENSEable City Lab server and embedded a video posted by the group to YouTube showing the individual prototype swarmbots, which already exist, and some computer renderings of what the working displays would look like. Exciting, eh?
This video from YouTuber NurdRage comes with a lot of caveats: the synthesis of TCPO from trichlorophenol and oxalyl chloride is relatively straightforward as syntheses go, and the starting materials are much easier to acquire, but they’re still not at all grocery-store type compounds. And it’s not a thing to attempt without the expertise, equipment, and facilities to do it safely. Plus the creepy “Jigsaw” voice effect that the narrator uses to disguise his identity doesn’t exactly inspire confidence. There’s nothing illegal about this procedure, as far as I know, but I think he wants to remain anonymous so nobody can sue him if they try to play along at home and end up burning it down.

I am getting ready for my first NYC runway show, the Fairytale Fashion Show, on Feb. 24th at Eyebeam. I am writing about some of the preparations, on CRAFT and Make: Online. This show will be of the technology fashion collection developed at FairytaleFashion.org, where technology is used to turn make-believe into reality. Last week, […]
John Baichtal @ Make: Online has the scoop: The 18th of February has been designated as Introduce a Girl to Engineering Day, an offshoot of National Engineers Week. A few days ago we asked Dr. AnnMarie Thomas, a professor of engineering at the University of St. Thomas, to share her thoughts on the occasion. If […]
