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 […]

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

Texas Instruments (TI) on November 10, unveiled its lowest-cost ultra-low-power MSP430 microcontrollers (MCUs) for sensing applications. Developers can now implement simple sensing solutions through a variety of integrated mixed-signal features in this family of MSP430 value line sensing MCUs, available for as low as US$0.25 in high volumes. Additions to the family include two new

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

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
