The Logitech Voice M380 wireless mouse looks and acts like a regular mouse but with a special button to initiate voice dictation. Baidu claimed recognition facilitates content creation at two to three times the speed of what one can type.

The device supports dictation in Chinese, English, and Japanese, and can translate content to English, Japanese, Korean, French, Spanish, and Thai. However, as of this month, you can only pick it up in China. There’s no word on when or if it will be available elsewhere.

The mouse uses Baidu’s AI open platform Baidu Brain speech technology. The Chinese tech company said of the platform:

As of September 2020, Baidu Brain has developed more than 270 core AI capabilities and created over 310,000 models for developers.

Baidu Brain is made of a security module and four components: a foundation layer (uses open-source Chinese deep learning platform Paddle Paddle, Kunlun AI processors, and databases); the so-called “perception” layer (aggregates the company’s algorithm in voice technology, computer vision and AR/VR); a cognition layer (integrates new information); and a platform layer.

[…]

The mouse comes in three colours, graphite, rose, and off-white, and costs around $30 (£22, €25).

Apparently, if the GPS on your shiny new DJI FPV Drone detects that it’s not in the United States, it will turn down its transmitter power so as not to run afoul of the more restrictive radio limits elsewhere around the globe. So while all the countries that have put boots on the Moon get to enjoy the full 1,412 mW of power the hardware is capable of, the drone’s software limits everyone else to a paltry 25 mW. As you can imagine, that leads to a considerable performance penalty in terms of range.

But not anymore. A web-based tool called B3YOND promises to reinstate the full power of your DJI FPV Drone no matter where you live by tricking it into believing it’s in the USA. Developed by the team at [D3VL], the unlocking tool uses the new Web Serial API to send the appropriate “FCC Mode” command to the drone’s FPV goggles over USB. Everything is automated, so this hack is available to anyone who’s running a recent version of Chrome or Edge and can click a button a few times.

A pair of good dice is a guilty pleasure for a tabletop RPG gamer. You can never have enough, but I can tell you this: None are going to be as flashy as Pixels. These dice have an ace up their sleeve that the rest of your dice don’t have, because they light up and allow you to play online.

Yes, Pixels are electronic dice. Externally they look like ordinary resin dice, but when you throw them, their numbers light up using programmable LEDs. This alone would be enough for many players to smash the buy button on Kickstarter, where the product has already raised $2 million. But there’s more: The Pixels have a Bluetooth connection.

These days it’s not easy to get together with friends to play. Lockdowns have made things very complicated, but even without a pandemic, RPG players live in different cities, move to other countries, or simply can’t meet for meet several hours at other people’s houses on a regular basis. Online role-playing platforms that allow you to play different games over video calls are popping up, and these dice are compatible with popular services like D&D Beyond, Roll20, and Foundry.

Both the lights and the Bluetooth run on small batteries and one die lasts around five hours on a charge. You can also turn off the LEDs to get in 20,000 rolls before the battery dies. Charging is wireless and uses an inductor hidden under one of its faces. The dice are sold separately or in kits containing D20, D12, D10, D8, D6, and D4 models.

[Sebastian] needed a good set of of shortcuts for OBS and decided to make a macro keyboard to help out. By the time he was finished, [Sebastian] had macro’d all the things and built a beautiful and smart peripheral that anyone with a pulse would likely love to have gracing their desk.

The design started with OBS, but this slick little keyboard turned into a system-wide assistant. It assigns the eight keys dynamically based on the program that has focus, and even updates the icon to show changes like the microphone status.

This is done with a Python script on the PC that monitors the running programs and updates the macro keeb accordingly using a serial protocol that [Sebastian] wrote. Thanks to the flexibility of this design, [Sebastian] can even use it to control the office light over MQTT and make the CO2 monitor send a color-coded warning to the jog wheel when there’s trouble in the air.

This project is wide open with fabulous documentation, and [Sebastian] is eager to see what improvements and alternative enclosure materials people come up with. Be sure to check out the walk-through/build video after the break.

Inspired to make your own, but want to start smaller? There are plenty to admire around here.

A new company called Metalenz, which emerges from stealth mode today, is looking to disrupt smartphone cameras with a single, flat lens system that utilizes a technology called optical metasurfaces. A camera built around this new lens tech can produce an image of the same if not better quality as traditional lenses, collect more light for brighter photos, and can even enable new forms of sensing in phones, all while taking up less space.

[…]

“The optics usually in smartphones nowadays consists of between four and seven lens elements,” says Oliver Schindelbeck, innovation manager at the optics manufacturer Zeiss, which is known for its high-quality lenses. “If you have a single lens element, just by physics you will have aberrations like distortion or dispersion in the image.”

More lenses allow manufacturers to compensate for irregularities like chromatic aberration (when colors appear on the fringes of an image) and lens distortion (when straight lines appear curved in a photo). However, stacking multiple lens elements on top of each other requires more vertical space inside the camera module.

[…]

Phone makers like Apple have increased the number of lens elements over time, and while some, like Samsung, are now folding optics to create “periscope” lenses for greater zoom capabilities, companies have generally stuck with the tried-and-true stacked lens element system.

[…]

Instead of using plastic and glass lens elements stacked over an image sensor, Metalenz’s design uses a single lens built on a glass wafer that is between 1×1 to 3×3 millimeter in size. Look very closely under a microscope and you’ll see nanostructures measuring one-thousandth the width of a human hair. Those nanostructures bend light rays in a way that corrects for many of the shortcomings of single-lens camera systems.

[…]

Light passes through these patterned nanostructures, which look like millions of circles with differing diameters at the microscopic level. “Much in the way that a curved lens speeds up and slows down light to bend it, each one of these allows us to do the same thing, so we can bend and shape light just by changing the diameters of these circles,” Devlin says.

[…]

nd the design doesn’t just conserve space. Devlin says a Metalenz camera can deliver more light back to the image sensor, allowing for brighter and sharper images than what you’d get with traditional lens elements.

Another benefit? The company has formed partnerships with two semiconductor leaders (that can currently produce a million Metalenz “chips” a day), meaning the optics are made in the same foundries that manufacture consumer and industrial devices—an important step in simplifying the supply chain.

New Forms of Sensing

Metalenz will go into mass production toward the end of the year. Its first application will be to serve as the lens system of a 3D sensor in a smartphone. (The company did not give the name of the phone maker.)

Researchers have made a smart school of robotic fish that swarm and swim just like the real deal, and they offer promising insights into how developers can improve decentralized, autonomous operations for other gizmos like self-driving vehicles and robotic space explorers. Also, they’re just pretty stinking cute.

These seven 3D-printed robots, or Bluebots, can synchronize their movements to swim in a group, or Blueswarm, without any outside control, per research published in Science Robotics this month from the Harvard John A. Paulson School of Engineering and Applied Sciences and the Wyss Institute for Biologically Inspired Engineering.

Equipped with two wide-angle cameras for eyes, each bot navigates their tank by tracking the LEDs lights on their peers. Based on the cues they observe, each robot reacts accordingly using an onboard Raspberry Pi computer and custom algorithm to gauge distance, direction, and heading.

“Each Bluebot implicitly reacts to its neighbors’ positions,” explains Florian Berlinger, a PhD candidate at SEAS and Wyss and first author of the research paper, per a press release. “So, if we want the robots to aggregate, then each Bluebot will calculate the position of each of its neighbors and move towards the center. If we want the robots to disperse, the Bluebots do the opposite. If we want them to swim as a school in a circle, they are programmed to follow lights directly in front of them in a clockwise direction.”

Previous robotic swarms could navigate in two-dimensional spaces, but operating in three-dimensional spaces like air or water has proven tricky. The goal of this research was to create a robofish swarm that could move in sync all on their own without the need for WiFi or GPS and without input from their human handlers.

Can a pair of unique spectacles banish nearsightedness without surgical intervention? Japan’s Kubota Pharmaceutical Holdings says its wearable device can do just that, and it plans to start releasing the product in Asia, where many people grapple with myopia.

The device, which the company calls Kubota Glasses or smart glasses, is still being tested. It projects an image from the lens of the unit onto the wearer’s retina to correct the refractive error that causes nearsightedness. Wearing the device 60 to 90 minutes a day corrects myopia according to the Japanese company.

Kubota Pharmaceutical has not disclosed additional details on how the device works. Through further clinical trials, it is trying to determine how long the effect lasts after the user wears the device, and how many days in total the user must wear the device to achieve a permanent correction for nearsightedness.

[…]

Kubota began clinical trials on the device last July after confirming the therapeutic effect of the mechanism using a desktop system. It is also developing a contact lens-type myopia correction device.

Kubota, which made its debut on the Tokyo Stock Exchange’s Mothers market for startups in December 2016, develops drugs and devices for the treatment of vision problems.

After three years of development, DARPA Subterranean (SubT) Challenge teams will get the chance to compete in the Final Event being held at the Louisville Mega Cavern in Louisville, Kentucky on September 21-23, 2021.

The DARPA SubT Challenge aims to develop innovative technologies that can rapidly map, navigate, and search complex underground environments such as human-made tunnel systems, urban undergrounds, and natural cave networks. Teams compete by demonstrating how their autonomy, networking, perception, and mobility capabilities perform on either physical courses in the Systems Competition or simulated environments in the Virtual Competition. The best performing team in the Systems Competition will be awarded a $2 million prize while the best performing team in the Virtual Competition will be awarded a $750,000 prize.

Over the last two years, teams faced a series of preliminary circuit events – the Tunnel Circuit, Urban Circuit, and Cave Circuit – to demonstrate how their solutions address the unique challenges of each subdomain. Teams will now tackle competition courses that include challenge elements from all three subdomains at the same time.

“Whether it’s the systems courses that we are building inside the Mega Cavern, or the wildly varying virtual environments we’re designing in the SubT Virtual Testbed, I’m excited to see how all of the SubT Challenge competitors build on the knowledge they gained during the Circuit Events to be successful in the Final Event.” said Dr. Timothy Chung, program manager for the Subterranean Challenge in DARPA’s Tactical Technology Office.

While many competitors are already preparing for the Final Event, new teams still have an opportunity to qualify for the Systems and Virtual Competitions. In order to participate, teams must deploy autonomous robotic systems – either real or virtual – into the competition courses to map, navigate, and search for artifacts of interest. The locations of each artifact must be reported with an accuracy of at least five meters to score a point. The competition courses are intentionally designed to emulate the dangers of rescue efforts in collapsed mines, post-earthquake search and rescue in urban underground settings, and cave rescue operations for injured or lost spelunkers.

NextMind is the latest in a long line of companies trying to harness the brain as a means of controlling our digital world. At first, its take on things may seem familiar: Don a headset which places a sensor on the back of your head, and it’ll detect your brainwaves which can then be translated into digital actions. One area where NextMind differs is that the sensor seems more practical than many we’ve seen and won’t leave you looking like a shower cap-wearing lab rat. In fact, the wearable can just as easily clip onto the rear of a snapback.

Beyond size and aesthetics, NextMind’s technology also seems fairly mature. I tried a demo (via the developer kit which goes on sale today for $399) and was surprised by how polished the whole experience was. Set up involved just one basic “training” exercise and I was up and running, controlling things with my mind. The variety of demos made it clear that NextMind is thinking way beyond simple mental button pushes.

There’s still a slight learning curve to get the “knack” — and it won’t replace your mouse or keyboard just yet. Mostly because we’ll need to wait for a library of apps to be built for it first, but also it’s still a new technology — and it takes some practice to become “fluent” with it, as my terrible performance on a mind-controlled game of Breakout can attest. But the diverse and creative demo applications I experienced do hold a lot of promise.

James Trew / Engadget

Right now, the applications are pretty simple: Mostly controlling media and games and so on, but NextMind’s founder and CEO, Sid Kouider is confident the technology will evolve to the point where you can simply think of an image to search for it, for example. There are also complementary technologies, like AR, where this sort of control not only seems apt, but almost essential. Imagine donning some augmented reality glasses and being able to choose from menu items or move virtual furniture around your room just with a glance.

The technology driving things is familiar enough: The sensor is an EEG that gently rests against the back of your head. This position is key, according to Kouider, as that’s where your visual cortex’s signals can most easily (or comfortably) be reached. And it’s these signals that NextMind uses, interpreting what you are looking at as the item or signal to be acted upon. In its simplest form, this would be a button or trigger, but the demos also show how it can be used to DJ, copy and paste and even augment (instead of simply replace) other inputs, such as that mouse or a game controller you are already using.

You won’t have to wait much longer to buy the first phone with an under-display camera — if you live in the right country. ZTE now plans to release the Axon 20 5G in 11 countries and regions on December 21st, including the UK, European Union, Japan and South Korea. The company didn’t reveal pricing, but said it would be available “soon.”

The centerpiece remains an uninterrupted 6.92-inch FHD+ OLED screen that uses a combination of materials, display syncing and a “special matrix” to hide a 32-megapixel selfie camera. You won’t find a cutout or notch here. It’s a thoroughly mid-range phone beyond that, though. The Axon 20 5G runs on a Snapdragon 765G chip with 8GB of RAM, and its stand-out features beyond the front camera include a 90Hz refresh rate and DTS:X Ultra 3D sound.

You can expect a 64MP main rear camera, an 8MP ultra-wide, a 2MP macro cam and a 2MP depth sensor. The 4,220mAh battery is also unspectacular given the size and 5G, although 30W fast charging should help it top up quickly.

Good stuff! I absolutely hate the cut out notch!

Today’s Inno Day 2020 event unveiled the Oppo X 2021 concept smartphone, which is all about its “continuously variable OLED display.” With a simple swipe on a button, the phone is able to transform between a regular 6.7-inch size and a tablet-like 7.4-inch size, and the software interface adapts accordingly for optimal experience — be it for single-hand usage or for multi-tasking.

Oppo

In a demo shown to Engadget, the prototype magically toggled between two screen sizes, with the video resizing itself on the fly to fill the screen. Similarly, the system menus and Twitter also switched between their phone interface and tablet interface to match the screen size. Oppo added that the user can freely customize the screen size, so you’re not just limited to either 6.7 inches or 7.4 inches. Hence the “continuously variable” label.

Oppo

Oppo wasn’t afraid to explain the magic here. The phone is essentially a motorized scroll, with a large part of the OLED panel laminated onto a “Warp Track” for improved strength, as it goes around a “Roll Motor” (with a 6.8mm scroll diameter) on the left to tuck itself into a hidden compartment. The phone itself consists of a “2-in-1 Plate” body construction: these two parts roll out simultaneously and evenly for better structural support.

Oppo applied for 122 patents for this project, 12 of which were on the scroll mechanism alone. The company stopped short at providing further details — no word on the screen specs, the panel’s supplier nor durability figures. Levin Liu, OPPO Vice President and Head of OPPO Research Institute, stressed that the Oppo X 2021 is still in concept stage, but he hopes to bring this technology to consumers “at the right time.”

In a year where it seems everything is both literally and figuratively on fire, it’s not surprising that we can now add Amazon’s Ring Video Doorbell to the list. Yes, it turns out that the device you purchased and installed for the purpose of making your home safer is itself a safety hazard. As a result, Amazon has issued a massive recall of its popular doorbell/spy camera. Here’s what to know.

What’s going on with Ring Doorbells?

Amazon is recalling approximately 350,000 Ring Video Doorbells (2nd Generation) sold through Amazon.com, Ring.com, and at third-party electronics and home goods stores in the United States and Canada between June and October 2020. The company made this decision after receiving reports of 85 incidents tied to incorrectly installed doorbells—23 of which involve doorbells igniting and causing minor property damage, in addition to eight reports of minor burns.

According to the Consumer Product Safety Commission (CPSC), the video doorbell’s battery can overheat if the wrong type of screws are used to install the device, posing fire and burn hazards. As a result, the CPSC advises that consumers immediately stop installing the recalled video doorbells.

You shouldn’t have one of these hacker vulnerable privacy invasion machines anyway.

A team of researchers has demonstrated for the first time a single-molecule electret – a device that could be one of the keys to molecular computers.

Smaller electronics are crucial to developing more advanced computers and other devices. This has led to a push in the field toward finding a way to replace silicon chips with molecules, an effort that includes creating single-molecule electret – a switching device that could serve as a platform for extremely small non-volatile storage devices. Because it seemed that such a device would be so unstable, however, many in the field wondered whether one could ever exist.

Along with colleagues at Nanjing University, Renmin University, Xiamen University, and Rensselaer Polytechnic Institute, Mark Reed, the Harold Hodgkinson Professor of Electrical Engineering & Applied Physics demonstrated a single-molecule electret with a functional memory. The results were published Oct. 12 in Nature Nanotechnology.

Most electrets are made of piezoelectric materials, such as those that produce the sound in speakers. In an electret, all the dipoles – pairs of opposite electric charges – spontaneously line up in the same direction. By applying an electric field, their directions can be reversed.

“The question has always been about how small you could make these electrets, which are essentially memory storage devices,” Reed said.

The researchers inserted an atom of Gadolinium (Gd) inside a carbon buckyball, a 32-sided molecule, also known as a buckminsterfullerene. When the researchers put this construct (Gd@C82) in a transistor-type structure, they observed single electron transport and used this to understand its energy states. However, the real breakthrough was that they discovered that they could use an electric field to switch its energy state from one stable state to another.

“What’s happening is that this molecule is acting as if it has two stable polarization states,” Reed said. He added that the team ran a variety of experiments, measuring the transport characteristics while applying an electric field, and switching the states back and forth. “We showed that we could make a memory of it – read, write, read, write,” he said.

Reed emphasized that the present device structure isn’t currently practical for any application, but proves that the underlying science behind it is possible.

“The important thing in this is that it shows you can create in a molecule two states that cause the spontaneous polarization and two switchable states,” he said. “And this can give people ideas that maybe you can shrink memory down literally to the single molecular level. Now that we understand that we can do that, we can move on to do more interesting things with it.”

A new study using lasers suggests that face shields and masks outfitted with an exhaust valve aren’t particularly great at protecting others from tiny respiratory droplets containing contagious germs like the coronavirus that causes covid-19. These aerosols can spill through and around these types of face equipment, the study found, weakening their potential to keep users from spreading an infection to others

Mask wearing has been embraced by public health experts as one of the most impactful ways to reduce the chances of someone giving covid-19 to other people. To a lesser extent, masks seem to also lower the risk of wearers catching the coronavirus from others. And despite a noisy contingent of skeptics, particularly in the U.S., much of the public in countries around the world have adapted to wearing masks in situations where they’re around people outside their household.

But there are many different kinds of face coverings that have become popular. Two in particular are plastic face shields and N95-respirator masks that come with exhaust valves. N95 respirators filter inhaled air from the outside, significantly reducing the potential for catching a respiratory infection, while the valves are intended to make breathing out easier. Shields are less cumbersome on the user’s breathing but have large gaps on the bottom and sides that, presumably, would let germs enter and escape fairly easily. Medical professionals typically wear face shields in addition to masks and other protective equipment, as a way to prevent sneezed or coughed droplets from a patient from landing in their eyes and other parts of their face.

In this new study, published Tuesday in the journal Physics of Fluids, both face shields and valve masks were shown to be pretty bad at stopping the flow of aerosols.

Engineers at Florida Atlantic University created a sort of light show to visualize what happens to our exhalations while using these coverings. They lit up the area around a mannequin’s mouth with lasers, outfitted the dummy with either an exhaust-valve mask or face shield, then pumped a mixture of water and glycerin through its mouth, creating a synthetic fog with a similar consistency to the aerosol droplets emitted by a person while coughing and sneezing. In the dark, the lasers were able to eerily illuminate the path of these droplets as they left the mannequin’s mouth.

The results were plain to see. The face shield did blunt the initial forward burst from the mouth, but the aerosolized droplets were then easily dispersed to the sides and even behind the shield in still high concentrations. Though the concentration of droplets dissipated as they moved further from the mannequin’s mouth, they would likely still be able to cover a lot of ground before they evaporated under the right conditions, such as indoor places with little air flow. Exhaust-valve N95 masks were even less effective at blocking the forward movement of droplets, with the valve serving as an easy escape hatch.

The team also tested several brands of surgical and N95 masks. Though these masks weren’t foolproof either at blocking aerosols, with some masks performing worse than others, they were still overall more effective in limiting aerosol concentration than either the shield or valve masks.

“Overall, the visuals presented here indicate that face shields and masks with exhale valves may not be as effective as regular face masks in restricting the spread of aerosolized droplets,” the authors wrote. “Thus, despite the increased comfort that these alternatives offer, it may be preferable to use well-constructed plain masks.”

NB The study link itself has videos too

Engineers at Purdue University have created a printing process by which you can coat paper or cardboard with “highly fluorinated molecules.” This then makes the coated paper dust, oil, and water-repellent, meaning you can then print multiple circuit layers onto the paper without smudging the ink. According to a paper the engineers published in Nano Energy, these “triboelectric areas” are then capable of “self-powered Bluetooth wireless communication.” That’s science-speak to say that paper printed and coated in this way doesn’t require external batteries as it generates electricity from contact with a user’s finger.

You can see a demonstration of how the tech works in these two videos. In the first video, Purdue engineers have a paper keypad that’s been treated with the aforementioned “omniphobic” coating. The paper keypad is then doused in some neon-green solution. In the second video, you can then see a person use the paper keypad to actually type on a laptop with a disabled keyboard.

In a third video, Purdue’s team printed a forward, back, mute, and volume bar on the back of a piece of paper. In it, you can see someone controlling audio playback by dragging their finger along the volume bar, as well as skipping forward and back in the music queue—some real David Blaine street magic-level shit.

While the tech itself is pretty cool, another neat aspect is that because it works on paper and cardboard, it would be relatively inexpensive, flexible, and quick to make. That makes it a good candidate for things like smart packaging.

“I envision this technology to facilitate the user interaction with food packaging, to verify if the food is safe to be consumed, or enabling users to sign the package that arrives at home by dragging their finger over the box to properly identify themselves as the owner of the package,” Ramses Martinez, an assistant professor at Purdue’s School of Industrial Engineering and one of the authors of the paper, said in a statement.

This isn’t the first time engineers have figured out novel uses for paper in electronics. A few months ago, researchers at the University of Missouri also created a paper-and-pencil medical wearable that could monitor things like heart rate, respiratory rate, glucose levels, body temperature, and sweat composition. In 2015, researchers from the University of Michigan created a stretchy conductor made of paper cut using the Japanese art of kirigami.

Purdue’s innovation is particularly interesting as it eliminates the need for external power sources, which makes applications like smart packaging less theoretical. That said, it’ll probably be a while before you can print your own paper Bluetooth keyboard.

Widespread internet outages knocked down Cloudflare, the PlayStation Network, Xbox Live, Amazon, Hulu, and a slew of other sites on Sunday morning, and it’s apparently all because of a single internet service provider: CenturyLink.

Given that Cloudflare’s online security services are designed to keep websites up and running, when it went down, so did dozens of the popular sites and services that rely on it, including Discord, Feedly, and League of Legends. Cloudflare began seeing “an increased level of HTTP 5xx class errors” early Sunday morning, according to the company’s status page. It later tweeted that issues with a “third-party transit provider” were affecting all of Cloudflare’s data centers that use that provider.

CenturyLink confirmed on Twitter that its technicians were working to fix an IP outage, which was resolved shortly before noon.

“We are able to confirm that all services impacted by today’s IP outage have been restored. We understand how important these services are to our customers, and we sincerely apologize for the impact this outage caused,” the company tweeted.

DownDetector showed reports of internet connectivity problems coming in from across the U.S. and western Europe on Sunday morning. Cloudflare chief tech officer John Graham-Cumming told CNN that “the extent of the problem required manual intervention” in addition to its automated bug detection systems.

It’s not the first time most of the internet’s gone dark because of issues with CenturyLink’s services. A nationwide blackout in 2018 took down Verizon mobile data, ATMs, and, most worryingly, the 911 emergency line in several parts of America. In response, Federal Communications Commission chairman Ajit Pai announced a federal investigation into CenturyLink.

“When an emergency strikes, it’s critical that Americans are able to use 911 to reach those who can help,” Pai said at the time. “The CenturyLink service outage is therefore completely unacceptable, and its breadth and duration are particularly troubling.”

As annoying as this morning may have been, I suppose we can be thankful that the outage wasn’t that bad at least.

Under-display cameras do a neat trick, allowing manufacturers to build all-screen phones without complex pop-up selfie cameras. Now, Xiaomi has unveiled its third-generation of under-display cameras and promised that the technology will be coming to the mass market “next year.”

Cameras that live under the screen present two problems: creating a dark “hole” on the display above the camera while making selfie photos look hazy and dull. Xiaomi said its third-generation tech can “perfectly disguise the front camera under the phone’s screen without ruining the edge-to-edge display effect.” In other words, you get a seamless full-screen display with nary a punch hole, cutout or other blemish in sight, while matching regular front cameras for photo quality.

Xiaomi developed its own pixel grid arrangement that allows light to pass through the gap area of sub-pixels. At the same time, each single pixel has a complete RGB subpixel layout with no sacrifice in pixel density. All of that means that the display pixel density above the camera is the same as elsewhere on the screen, showing the “same brightness, color gamut and color accuracy.” Xiaomi also optimized the camera algorithm, claiming it performs the same as conventional front cameras.

A review at the Android Police site calls Pine64’s new Linux-based PinePhone “the most interesting smartphone I’ve tried in years,” with 17 different operating systems available (including Fedora, Ubuntu Touch, SailfishOS, openSUSE, and Arch Linux ARM): There’s a replaceable battery, which is compatible with batteries designed for older Samsung Galaxy J7 phones. It’s good to know that even if PinePhone vanished overnight, you could still purchase new batteries for around $10-15…

There’s a microSD card slot above the SIM tray, which supports cards up to 2TB in size. While it can be used as extra storage, just like the SD slots in Android phones and tablets, it can also function as a bootable drive. If you write an operating system image to the SD card and put it in the PinePhone, the phone will boot from the SD card. This means you can move between operating systems on the PinePhone by simply swapping microSD cards, which is amazing for trying out new Linux distributions without wiping data. How great would it be if Android phones could do that?

Finally, the inside of the PinePhone has six hardware killswitches that can be manipulated with a screwdriver. You can use them to turn off the modem, Wi-Fi/Bluetooth, microphone, rear camera, front camera, and headphone jack. No need to put a sticker over the selfie camera if you’re worried about malicious software — just flip the switch and never worry about it again…. For a $150 phone produced in limited batches by a company with no previous experience in the smartphone industry, I’m impressed it’s built as well as it is…

I look forward to seeing what the community around the PinePhone can accomplish.
A Pine64 blog post this weekend touts “a boat-load of cool and innovative things” being attempted by the PinePhone community, including users working on things like a fingerprint scanner or a thermal camera, plus a community that’s 3D-printing their own custom PinePhone cases. And Pine64 has now identified three candidates for a future keyboard option (each of which can be configured as either a slide-out or clamshell keyboard): I feel like we have finally gotten into a good production rhythm; it was only last month we announced the postmarketOS Community Edition of the PinePhone, and this month I am here to tell you that the factory will deliver the phones to us at the end of this month… I don’t know about you, but I think that this is a rather good production pace. At the time of writing, and based on current sale rates, the postmarketOS production-run will sell out in a matter of days…
