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.

In the late 1950s, a truck carrying a cement mixer crashed on E300 Road between Talala and Winganon, Oklahoma. Apparently too heavy for anyone to deal with, the mixer sat for decades where it was occasionally graffitied or whimsically decorated. In 2011, artists Heather and Barry Thomas celebrated their wedding anniversary by transforming the drum […]

When you’re ready to take a break from doomscrolling, stop and send your scream to Iceland. It will be blasted from a real speaker that has been placed in one of the country’s regions. “Scream therapy.” You’ve been through a lot this year and it looks like you need the perfect place to let your […]
It’s tempting for many young professionals to assume that because they’ve spent most of their lives posting links to Facebook or pushing selfies to Instagram that they have the skills needed to be a digital marketer. Creating compelling content is certainly important, but if you’re not up to speed on search engine optimization (SEO), how […]
With everybody working from home now, it’s natural to start thinking about careers where not going into the office is more the norm than the exception. Better yet, many are looking to start careers as freelancers, professionals who build their livelihoods around the scope of their talent and not the fortunes of one all-encompassing employer. […]
“The way to have power is to take it.” — Boss Tweed. We think an 18th-century political power broker probably had a different definition of power in mind when he made that statement, yet the sentiment still applies. We’ve all got devices all but falling out of our pockets and the need for power to […]
