Collaborate Disseminate
In a world where smartphones have commoditized precision MEMS Sensors, the stage is set to reimagine clusters of these sensors as something totally different. That’s exactly what [chronopoulos] did, taking …read more Continue reading Laser Theremin Turns Your Hand Swooshes into Music
Atomic force microscopy, laser ablation, and etching with a witches brew of toxic chemicals: sounds like [Zachary Tong] has been playing in the lab again, and this time he found …read more Continue reading Getting a Fly’s-Eye View with Microfabricated Lens Arrays
When someone offers to write you a check for $5 billion for your company, it seems like a good idea to take it. But in the world of corporate acquisitions …read more Continue reading Hackaday Links: June 13, 2021
For anyone that’s fiddled around with a magnifying glass, it’s pretty easy to understand how optical microscopes work. And as microscopes are just an elaboration on a simple hand lens, …read more Continue reading Macro Model Makes Atomic Force Microscopy Easier to Understand
The team that hacked Amazon Echo and other smart speakers using a laser pointer continue to investigate why MEMS microphones respond to sound. Continue reading Laser-Based Hacking from Afar Goes Beyond Amazon Alexa
If you’re a human or other animal with two ears, you’ll probably find great utility in your ability to identify the direction of sounds in the world around you. Of course, this is really just a minimal starting point for such abilities. When [John Duffy] set out to build his …read more

A company spun off from the Fraunhofer Institute for Photonic Microsystems is looking commercialize a micro loudspeaker made from 100 percent silicon. After successful seed funding, Arioso Systems GmbH is now ready to take the technology to market.Cont… Continue reading Silicon-based speaker set to make some noise in future earphones
What do potato chips and lost car keys have in common? On the surface, it would seem not much, unless you somehow managed to lose your keys in a bag of chips, which would be embarrassing enough that you’d likely never speak of it. But there is a surprising link …read more
