Daren Schwenke's 3D printed blooming rose embeds a capacitive touch sensor -- a magnetic wire -- in one of the leaves, which trips an Arduino-controlled actuator that changes the rose's lighting and causes the petals -- 3D printed and then shaped over a hot chandelier bulb -- to splay open or fold closed.
The build log reveals a lively open-source hardware/free software collaboration that is a miniature, perfect case-study.
What finally materialized is a terrific combination of common hacker technologies. The petals are printed flat in nylon, then formed over a hot incandescent chandelier bulb. The stem and leaves are also printed, but the side stem has a piece of magnet wire embedded in the print as a capacitive touch sensor; when the leaf is touched, the rose blossom opens or closes. Magnet wire for the LEDs and a connecting rod for the mechanics run through the main stem to the base, where a 9g servo is responsible for controlling the bloom. The whole thing is controlled, naturally, with an Arduino. To move the project along a little more quickly, [Daren] enlisted the help of another Hack Chat denizen, [Morning.Star], who did an amazing job on the software without any access to the actual hardware.

I'm in the midst of couple of weeks' worth of lectures, public events and teaching, and you can catch me in Toronto (for Word on the Street, Seeding Utopias and Resisting Dystopias and 6 Degrees); Newry, ME (Maine Library Association) and Portland, ME (in conversation with James Patrick Kelly).
Octavia Butler (previously), the brilliant Afrofuturist, McArthur Genius Grant-winning science fiction writer, died far, far too soon, leaving behind a corpus of incredible, voraciously readable novels, and a community of writers who were inspired by her example.

On the one hand, nostalgia is “a corruption of the historical impulse,” according to William Gibson. On the other hand, “Super Mario Bros.” will never not be cool. Luckily, there’s a way to satisfy that retro gaming while still keeping an eye on the future: The GameShell Kit. This thing is simultaneously the last handheld […]
The field of data analytics can get intimidating, even for business professionals who constantly rely on it. But at its heart, its purpose is to simplify. To take mounds of information and distill their insights into a single clear picture. Currently, the go-to software for painting that picture is Tableau. And if you want to […]
