The flat panels offer a lightweight, compact, low-profile alternative to traditional antennas. These flat panel reflectors may be better suited for modern communications. (Photo from Los Alamos National Laboratory)   You've most likely seen the standard antennas that adorn various rooftops and cell towers, 3D dishes, and microwave horns used for modern communication. This traditional design could soon be upgraded thanks to engineers at Los Alamos National Laboratory. The team recently deve ...
Introduction Coil Test Adapter Build and Initial Tests Uh-oh moment Motor Tests A Case for the New Adapter Conclusions   Introduction  This is an update to my original review of the MetraHit Coil motor testing multimeter from Gossen Metrawatt.   MetraHit Coil Motor Testing Multimeter Blog 1   My primary interest in this instrument is the coil test function, that is for detecting inter-turn faults within motor stator windings. On testing a number of ...
Researchers discovered trace amounts of superconductive grains in this piece of Mundrabilla meteorite, which is the first identification of superconductive grains in a meteorite. (Image Credit: James Wampler)   Scientists from UC San Diego and Brookhaven Laboratory in New York have discovered trace amounts of superconductive material inside two meteorites. After examining 15 pieces of comets and asteroids, they found that two meteorites named “Mundrabilla” and “GRA 95205& ...
Microsoft’s split-style controller was recently revealed in a YouTube video. It allows a user to play video games using a controller attached to smartphone/tablet devices instead of using the touch screen. (Image Credit: Microsoft Research) A few years ago, Microsoft Research developed an Xbox style controller that could be attached to a wide range of mobile and tablet devices, providing more tactile controls. Last year, a Microsoft patent filing was discovered, revealing details of the ...
Introduction  I decided it was time for me to take a look at another insulation tester. This particular one is from Hioki, the IR4058-20.

By using the Portal device, users are able to access data on a Wi-Fi-enabled device in regions where an internet shutdown is being enforced by the government. (Image Credit: Qifan Zhao, The Fallback Project)   Humans have a right to access information, especially if it’s on the internet, but sometimes that’s restricted due to government-enforced shutdowns.  Students at London’s Royal College of Art and Imperial College have developed a system, called Fallback, which ...
Scientists have created a “body-on-a-chip” that consists of mini-organs, including a heart that beats, lungs that breathe, a liver, blood vessels, colon, and brain. Image is a sample of one creation. (Image Credit: WFIRM) Medical researchers at the Wake Forest Institute for Regenerative Medicine (WFIRM) in North Carolina have developed the most advanced lab model of a human body.  The body-on-a-chip is a system of microscopic organs made of human cells and stem cells featuring ...
Doctors recently used CRISPR to help treat a patient suffering from blindness (Image credit: Maurizio De Angelis/Science Photo Library)   Over the past few decades, researchers and doctors have been looking for ways to help restore sight for the blind. But one team of scientists made a significant breakthrough recently by using CRISPR inside the human body for the first time. Doctors at the Casey Eye Institute at the Oregon Health & Science University in Portland use the tool to alter ...
The neighbor atom, as shown in red, is used to calculate the measurements of the blue atom. (Image Credit: RIKEN)   Researchers from the RIKEN Center for Emergent Matter Science in Japan have successfully taken repetitive measurements of the spin of an electron in a silicon quantum dot (QD), without altering the spin. This process of “non-demolition” measurement is crucial for building quantum computer systems that are fault-tolerant. The team published their findings in the Jo ...
Mark Hamill speaking to Bella, who is the first one to wear the R2D2 bionic hand cover in the United States. (Image Credit: OpenBionics/YouTube)   OpenBionics, a company that specializes in building bionics for amputees, has recently released an R2D2 bionic cover arm for Star Wars fans. One of the recipients wearing the R2D2 arm is an 11-year old devoted Star Wars fan who also received a Skype call from Mark Hamill, who retweeted her fundraiser for the bionic arm. She managed to raise near ...
The robot finger has the ability to localize touch with high precision over a large, multi curved surface. (Image Credit: Columbia Engineering)   Researchers from Columbia Engineering University have developed a new robotic finger that has a sense of touch. The finger can localize touch with high precision to 1mm over a large, multi curved surface. It could be used for robotic manipulation in a variety of tasks, like manufacturing or nuclear decommissioning. The team published their findin ...
The new electronic state of matter could advance research in quantum physics, further advancing technology.  (Image Credit: Yun-Yi Pai)   Researchers from the University of Pittsburgh Department of Physics and Astronomy have announced the discovery of a new electronic state of matter on the quantum scale. It forms when bunches of two, three, four and five electrons clump together while in transit. Their new discovery could further advance our understanding of quantum physics. The team ...
The virtually aided tactile enhancement system (VATES) allows more motion control. (Image Credit: Rongrong Bao.)   Humans rely on the sense of touch to manipulate objects, but that can be restricted due to injuries or wearing gloves. This can be problematic for surgeons who often have trouble manipulating soft tissues while wearing gloves. Astronauts also have issues handling equipment during spacewalks at the International Space Station. Researchers from China have developed an advanced ...
Introduction What Crimp Pins and Sockets? Crimp Tools Crimp Tools Tested Engineer PA-09 Multicomp HT-225D AMP 90202-2 Crimp Socket Result Photos Crimp Pin Result Photos Heat Shrink Summary   Introduction Making your own jumper cables is quite high on the list of unproductive things to do : ) since they are available ready-made in pin, socket and pin and socket versions. Sometimes I'll just use solid core wire if it is going into board sockets. How ...
AI may be the way to fight back against the spread of diseases (Photo from CDC)   The coronavirus has been spreading at an alarming rate since its initial outbreak. So far, there have been roughly 305 deaths and more than 14,300 people infected and unfortunately, those numbers keep rising. While doctors and scientists around the world are scrambling to figure out the virus’s origin and how to fight back, many are turning to AI solutions to help them learn more about the mysterious vi ...
