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.

Karl Schroeder (previously) is literally the most visionary person I know (and I've known him since 1986!): he was the first person to every mention "fractals" to me, then "the internet" and then "the web" -- there is no one, no one in my circle more ahead of more curves, and it shows in his […]
Veteran reviewer/interviewer Rick Kleffel (previously) has just posted a long podcast interview (MP3) with Neal Stephenson, discussing his latest novel, Fall; or, Dodge in Hell ("a science fiction novel with a fantasy novel stuck inside of it").
A couple of weeks ago, I was thrilled to hear Subgenius founder, the Reverend Ivan Stang, interviewed on the Comedy on Vinyl podcast (previously) and to discover that the Church of the Subgenius was selling a $35 Salvation/Membership/Ordainment kit that was chock full of goodies.
So you cut the cord and got rid of cable? Join the steadily growing club. But while you’re out picking a streaming service, you might find one big blind spot: Local TV and sports, not to mention first-run programming from the big cable networks. Luckily, there’s a throwback way to get it for free: The […]
Even if you feel like AirPods are worth the price tag, you’ve got to admit there’s a certain anxiety that comes with using them. What if I lose them? What if they get wet in the rain? Or drenched in sweat? Or fall into the drink you dropped them into? Shiny tech is great, but […]
With the quick-fix appeal of video games and their own cell phones, it can be tough to keep kids focused on supposedly “educational” toys. And while it may seem counter-intuitive to fight tech with more tech, we’re all in when it comes to the Toybox 3D Printer. We’re not sure if anyone had envisioned a […]
