Collaborate Disseminate
Inspired by a prank tweet, [Sam Ettinger] endeavored to create an SMD seven-segment display. The NanoRaptor NanoSegment implements a panel of seven-segment display modules sized at “0806” each or just …read more Continue reading Nano-Sized 7-Segment LED Display on a Surface Mount Module
If you wonder how it’s possible to fit a fitness tracker into a ring, well, you’re not alone. [Becky Stern] sent one off to get CT scanned, went at it …read more Continue reading Becky Stern, David Cranor, and a CT Scanner vs the Oura Ring
Perhaps the second most famous law in electronics after Ohm’s law is Moore’s law: the number of transistors that can be made on an integrated circuit doubles every two years …read more Continue reading Smaller is Sometimes Better: Why Electronic Components are So Tiny
If you want to track a snail, you need a tiny instrumentation package. How do you create an entire data acquisition system, including sensors, memory, data processing and a power …read more Continue reading Snails, Sensors, and Smart Dust: The Michigan Micro Mote
One of the selling points of the Arduboy is how slim [Kevin Bates] was able to get the Arduino-compatible game system, which is perhaps less surprising when you realize that it originally started out as a design for an electronic …read more

What’s tiny and on track to be worth $22 billion dollars by 2018? MEMS (Micro Electrical Mechanical Systems). That’s a catch-all phrase for microscopic devices that have moving parts. Usually, the component sizes range from 0.1 mm to 0.001 mm, which is tiny, indeed. There are some researchers working with even smaller components, sometimes referenced as NEMS (Nano Electrical Mechanical Systems).
MEMS have a wide range of applications including ink jet printers, accelerometers, gyroscopes, microphones, pressure sensors, displays, and more. Many of the sensors in a typical cell phone would not be possible without MEMS. There are many ways that …read more
Light up jewelry is nothing new – we see wearables all the time here. But home brew, self-contained, programmable LED earrings that are barely larger than the watch batteries which power them? That’s something worth looking into.
Settle back and watch [mitxela]’s miniature wizardry in the video below, but be forewarned: it runs 36 minutes. Most of the video is necessarily shot through a microscope where giant fingers come perilously close to soldering iron and razor blade.
The heart of the project is an ATtiny9, a six-legged flea of a chip. The flexible PCB is fabricated from Pyralux, which is …read more
