To Build the World’s Smallest Atomic Clock, Trap a Nitrogen Atom in a Carbon Cage

The Norwegian explorer had set a new record for the closest approach to the North Pole, and now he was moving quickly over unbroken sea ice toward Cape Fligely and home. But then came a sickening realization: In his eagerness to break camp, he had forgotten to wind the chronometers. He had lost track of

Exploring the Open Source Ethernet Broadcaster

In this second and final post we will go deep inside the Ethernet audio streaming transceiver firmware. Recently, we have presented an Ethernet audio streaming unit. In particular, we have shown how to configure the boards to work with other similar devices or with VLC Media Player, setting up a point-to-point or a broadcast streaming in all

ROBOBEE – A FLYING MICROBOT THAT CAN PERFORM SEARCH AND RESCUE MISSIONS

Inspired by the biology of a bee, researchers at the Wyss Institute developed RoboBees, man-made microbots that could perform endless roles in agriculture or disaster relief. A RoboBee is about half the size of a paper clip, weighs less than one-tenth of a gram, and flies using materials that contract when an electric pulse is applied. Now, they progressed

CH340E, A NEW SMALL SERIAL TO USB CHIP

WCH, a Chinese integrated circuits manufacturer, has just released a new serial to USB chip called CH340E. Unlike other CH340 chips, it doesn’t require an external crystal and also needs less PCB space and BOM. CH340 is a 3x3mm tiny chip comes in MSOP10 package and has 10 pins. Although it is smaller than other alternatives, it is a

ICECOOL – AN INTRA-CHIP COOLING SYSTEM THAT IS MORE EFFICIENT

n the Moore’s Law race to keep improving computer performance, the IT industry has turned upward, stacking chips like nano-sized 3D skyscrapers. But those stacks have their limits, due to overheating. Researchers from IBM have solved this problem by developing an intra-chip cooling system as a contribution to ICECoolprogram research project by the DARPA (Defense Advanced Research Projects Agency). Today, chips are typically cooled by fans
