German semiconductor maker Infineon Technologies AG announced that it’s producing a printed circuit board (PCB) that dissolves in water. Sourced from UK startup Jiva Materials, the plant-based Soluboard could provide a new avenue for the tech industry to reduce e-waste as companies scramble to meet climate goals by 2030. Jiva’s biodegradable PCB is made from Read more about Water-soluble circuit boards could cut carbon footprints by 60 percent[…]

Today, the Institute of Electrical and Electronics Engineers (IEEE) has added 802.11bb as a standard for light-based wireless communications. The publishing of the standard has been welcomed by global Li-Fi businesses, as it will help speed the rollout and adoption of the  data-transmission technology standard. Advantages of using light rather than radio frequencies (RF) are Read more about 100x Faster Than Wi-Fi: Light-Based Networking Standard Released[…]

The concept of Continuous Integration (CI) is a powerful tool in software development, and it’s not every day we get a look at how someone integrated automated hardware testing into their system. [Michael Orenstein] brought to our attention the Hardware CI Arena, a framework for doing exactly that across a variety of host OSes and microcontroller Read more about How Hardware Testing Got Plugged Into A Continuous Integration Framework[…]

When should you be concerned about a NAS hard drive failing? Multiple factors are at play, so many might turn to various SMART (self-monitoring, analysis, and reporting technology) data. When it comes to how long the drive has been active, there are backup companies like Backblaze using hard drives that are nearly 8 years old. Read more about “Clearly predatory”: Western Digital sparks panic, anger for age-shaming HDDs, making it impossible to repair RAID pools[…]

A US federal court this week gave final approval to the $50 million class-action settlement Apple came to last July resolving claims the company knew about and concealed the unreliable nature of keyboards on MacBook, MacBook Air and MacBook Pro computers released between 2015 and 2019. Per Reuters (via 9to5Mac), Judge Edward Davila on Thursday Read more about US judge grants final approval to Apple’s $50m broken ‘butterfly’ keyboard settlement[…]

Last week the Telegraph reported that a recent firmware update to HP printers “prevents customers from using any cartridges other than those fitted with an HP chip, which are often more expensive. If the customer tries to use a non-HP ink cartridge, the printer will refuse to print.” Some HP “Officejet” printers can disable this Read more about HP Can’t Fix Bricked Printers After Faulty Firmware Update which bricked non HP-ink cartridges[…]

Hewlett-Packard, or HP, has sparked fury after issuing a recent “firmware” update which blocks customers from using cheaper, non-HP ink cartridges in its printers. Customers’ devices were remotely updated in line with new terms which mean their printers will not work unless they are fitted with approved ink cartridges. It prevents customers from using any Read more about HP disables customers’ printers if they use ink cartridges from cheaper rivals[…]

The Council and the European Parliament have reached today a provisional political agreement on the regulation to strengthen Europe’s semiconductor ecosystem, better known as the ‘Chips Act’. The deal is expected to create the conditions for the development of an industrial base that can double the EU’s global market share in semiconductors from 10% to Read more about Chips Act: Council and European Parliament strike provisional deal[…]

DGIST Professor Yoonkyu Lee’s research team used intense light on the surface of a copper wire to synthesize graphene, thereby increasing the production rate and lowering the production cost of the high-quality transparent-flexible electrode materials and consequently enabling its mass production. The results were published in the February 23 issue of Nano Energy. This technology Read more about Researchers synthesize graphene using intense light[…]

[…] “With the help of a quantum annealer, we demonstrated a new way to pattern magnetic states,” said Alejandro Lopez-Bezanilla, a virtual experimentalist in the Theoretical Division at Los Alamos National Laboratory. Lopez-Bezanilla is the corresponding author of a paper about the research in Science Advances. “We showed that a magnetic quasicrystal lattice can host Read more about Qubits put new spin on magnetism: Boosting applications of quantum computers[…]

[…] In the latest advance in nano- and micro-architected materials, engineers at Caltech have developed a new material made from numerous interconnected microscale knots. The knots make the material far tougher than identically structured but unknotted materials: they absorb more energy and are able to deform more while still being able to return to their Read more about Knots smaller than human hair make materials unusually tough and (de|re)formable[…]

Secondhand MacBooks that retailed for as much as $3,000 are being turned into parts because recyclers have no way to login and factory reset the machines, which are often just a couple years old. “How many of you out there would like a 2-year-old M1 MacBook? Well, too bad, because your local recycler just took Read more about Perfectly Good MacBooks From 2020 Are Being Sold for Scrap Because of Activation Lock[…]

As the cryptocurrency market currently goes through one of its worst nosedives in recent years, miners are trying to get rid of their mining hardware. Due to the crashing prices of popular crypto coins, numerous Chinese miners and e-cafes are flooding the market with graphics cards they no longer need. Miners, e-cafes, and scalpers are Read more about Miners flood market with GPUs they no longer need as cryptocurrencies crash[…]

[…] Last year, researchers from the National Taiwan University’s Interactive Graphics (and Multimedia) Laboratory and the National Chengchi University revealed their Hair Touch controller at the 2021 Computer-Human Interaction conference. The bizarre-looking contraption featured a tuft of hair that could be extended and contracted so that when someone tried to pet a virtual cat, or Read more about VR Controller Lets You Feel Objects Slip Between Your Fingers[…]

Scientists from the Physics and Engineering Department of the UK’s Lancaster University have published a paper detailing a breakthrough in the mass production of UltraRAM. Researchers have pondered over this novel memory type for several years due to its highly attractive qualities, and the latest breakthrough means that mass production on silicon wafers could be Read more about UltraRAM Breakthrough Brings Combined Memory and Storage to a single wafer[…]

[…] Kinetic Architecture is a concept on which buildings are designed to allow parts of the structure to move. CyberPowerPC took this idea and created a KINETIC chassis with 18 individually controlled articulating vents that open and close automatically, all based on the computer’s current internal ambient temperatures. “We are entering 2022 with some of Read more about CyberPowerPC case uses Kinetic Architecture to adjust airflow in real-time[…]
