A new passive technology could help future wireless networks reach places where signals struggle today. Dead zones are one of the most persistent problems in wireless communications. Whether it’s a basement office, a warehouse aisle, a tunnel, or a crowded indoor venue, signals often struggle to reach every corner. The challenge is expected to grow [...]

As artificial intelligence, cloud computing, and online services continue to grow, the demand for faster and more energy-efficient computer hardware is rising rapidly. Now, researchers in Japan have developed a new type of magnetic memory that can be rewritten using a single pulse of laser light instead of electric current, potentially paving the way for […]

Just like snowflakes, no two TikTok For You pages look alike. And that is intentional. The social media site’s highly personalized—and black box-like—recommendation algorithm has long been considered its “secret sauce,” after all. But how much control do the platform’s billion-plus daily users have over the topics that show up on their feed? The social […]

Falling overboard from a ship is one of the most dangerous emergencies at sea. Every minute matters, and the chances of survival can quickly decrease as people become exhausted, suffer from cold water exposure, or drift far away from the vessel. Researchers at the Technical University of Denmark (DTU) are developing a new autonomous rescue […]

Researchers at the University of Cambridge and startup company GlitterinTech have developed a tiny, low-cost device that could bring powerful chemical sensing capabilities to wearable technology. The new device is an optical spectrometer—a tool that analyzes how light interacts with materials. Spectrometers are widely used in science, medicine, manufacturing, and environmental monitoring because they can […]

A wearable lens used the retina to reach mood circuits deep in the brain and reverse depression-like changes in mice.

Scientists have finally packed a laboratory-class ultrafast laser onto a tiny photonic chip. Ultrafast lasers generate bursts of light that last only a few hundred femtoseconds, each one just a quadrillionth of a second long. These extremely short pulses are used in a wide range of technologies, including precision manufacturing, eye surgery, and optical frequency [...]

Researchers may have unlocked the future of computing by turning flat silicon chips into densely stacked 3D architectures. For decades, the semiconductor industry has boosted computing power by making transistors smaller and fitting more of them onto a single chip. That strategy has fueled remarkable advances in electronics, but it is now approaching fundamental physical [...]

With a shortage of some components driving up costs of consumer electronics, refurbished devices are an attractive alternative to buying new.

A new MIT-designed lidar chip uses specially engineered antennas to reduce interference and widen the sensor’s field of view. From self-driving cars navigating busy streets to drones surveying disaster zones, lidar has become one of the most important technologies for helping machines perceive the world in three dimensions. By sending out rapid pulses of infrared [...]

Introduction This project began life in 2017 when the author had just begun experimentation with GPIO pins on a Raspberry Pi 3. At that point in time a greatly appreciated Christmas present  was an “Explorer Hat” module which provided the aspirant programmer with 5 volt tolerant input and output channels (analogue and digital) , capacitive...

Introduction This elaborates some of the claims in my insights article on digital audio. The Sinc Function Upsampling and Zero Insertion The first link in my insights article has a section on filters, but I will detail the most critical case. The bit depth is assumed to be so large for all practical purposes that...

Introduction First, we need some background in Digital Signals. This can be mathematically quite advanced, but since I would like this article to be accessible to as wide an audience as possible, here is a link that explains what is needed (not even Calculus is required): https://brianmcfee.net/dstbook-site/content/intro.html Shannon’s Sampling Theorem An important point not emphasized...
