After a conference call today organized by Stephen Schwarzman — Blackstone CEO and head of the president’s Strategic and Policy Forum — the advisory council decided that the best thing to do in light of Trump’s recent comments about the Charlottesv…
Now that Jawbone is making the move from consumer wearables to medical devices, just what is it up to? Bloomberg’s sources might have an idea. They’ve obtained investment pitch documents from October 2016 indicating that Jawbone hoped to draw on tech…
Because, you know, there definitely isn’t already too much TV to watch.
Meet the “New Right.” Same as the alt-right?
Forever’s gonna start on Aug. 21.
“Whatever party or wherever we come from, America will have to stand tall again for values.”
Remember back in May, when Google announced plans to let people make free phone calls through the Google Home? That feature is rolling out starting today (alas, only for folks in U.S./Canada). Say something like, “OK Google, call the nearest sandwich shop,” and it’ll connect the dots and help you get your grub. Or, if you give Google Home access to your contacts, you can… Read More
While most levitation is achieved with magnets, it’s also possible to suspend small objects in air using sound waves. Thanks to engineer Asier Marzo, you can even create your own acoustic levitator, which can float lightweight objects like water droplets, styrofoam beads, and even insects.
The system uses a 3D printed rig that holds two opposing grids filled with 36 tiny ultrasonic transducers each. An Arduino Nano, a power supply, and a motor drive board control the transducers, which basically push and pull on small objects you place in their path, holding them in mid-air. Levitation is achieved by pushing air out of both top and bottom transducers, which apply an equivalent amount of pressure from above and below the objects.
Asier describes the highlights of the build in the video below:
Neat, eh? Now if you’re ready to build your own acoustic levitator, check out the full build log over on Instructables. There’s a great article on the physics behind acoustic levitation over on How Stuff Works too.
I’m done hearing about your “silent influence.”
