Battery life has long been a key limiting factor in drone use. Although there are commercial models that can stay aloft for 45 minutes or longer on a single charge, being able to keep drones in the air for longer would be helpful for many purposes. Researchers at the University of Southern Denmark have been working on that issue for several years by developing drones that can recharge directly from power lines.

This time around, the scientists attached a gripper system to a Tarot 650 Sport drone, which they customized with a electric quadcopter propulsion system, an autopilot module and other components. When the drone's systems detect that the battery is running low, the device employs its camera and millimeter-wave radar system to pinpoint the closest power line, as New Atlas notes.

The drone then flies up to the power line from underneath, using a pair of inward-sloping arms to guide the cable into the gripper. An inductive charger pulls current from the power line. When the battery is full, the gripper opens and the drone continues on its way.

At the outset, the idea is for drones that inspect power lines to use this charging system. The researchers first showed off a self-charging drone that tops up its battery from power lines in 2022. This time around, they improved the gripper system and demonstrated a real-world use case for the tech.

In a paper they're presenting at next month's IEEE International Conference on Robotics and Automation, the team described the project as "to the best of our knowledge, a first-in-the-world system with the ability to sustain operation throughout many inspection/charging cycles powered by energy harvesting from power lines in a real outdoor environment." In arguably the most successful test, the drone stayed aloft for over two hours through five cycles of power line inspection and charging.

Drones have been used for years to monitor and inspect power lines. They're particularly useful in remote areas, such as mountain tops, where examining power lines manually is a tough ask. Still, it's hard not to feel a little uneasy about drones clamping onto power lines. If anything goes wrong and a drone somehow ends up damaging a power line, an entire region could lose electricity. Charging pads for drone exist and may be a safer option, but they'd require extra space for infrastructure.

Google has finally launched its long-awaited Find My Device network after teasing it at last year’s I/O event. The technology leverages a crowdsourced network of over a billion Android devices to help people locate lost gadgets, with a basic functionality in line with similar offerings from Apple and Tile. It’s rolling out today to Android users in the US and Canada, with a global release coming soon.

Once installed, people can use the app to locate compatible Android phones and tablets. The tool will cause them to ring at your command and their location will pop up on a map. This map data works even if the items are offline. Pixel 8 and Pixel 8 Pro smartphones will appear on the map if they’re powered off or if the battery is completely dead. That sounds pretty handy.

The technology isn’t yet available for everyday items, but that’s coming soon. Bluetooth tracker tags from Chipolo and Pebblebee will get integrated into the Find My Device app in May. This will let users locate just about anything, including car keys, purses, wallets and, hopefully, wandering felines. The upcoming tags are being built specifically for the network.

Google

The Pebblebee offerings include tags, clips and slim cards for wallets. They hit store shelves in late May or early June. Chipolo is making versions of its One Point and Card Point trackers for Android devices, which will arrive in May. Google says more trackers are coming later this year, including products made by Motorola and eufy.

Google’s Find My Device service also integrates with Nest smart home gadgets. If you lose something in the home, the Find My Device app will show you the location of the item in relation to pre-existing Nest devices. This should help provide an “easy reference point” to snatch them back up.

Finally, there’s a nifty feature that lets you share the location of an item with other people, so friends and family can keep an eye on precious belongings. Google says it’ll let folks “easily divide and conquer if something goes missing.” 

The new Find My Device tracking technology works on devices running Android 9 and above. That OS came out in 2018, so it means a whole lot of people will have access to this service. As for compatible products beyond Android devices and Bluetooth tags, the company says future software updates will allow integration with a full range of headphones from JBL and Sony.

Of course, there are the usual privacy concerns with this kind of thing. Google says that users can opt out of the service via a web portal if they feel uncomfortable, according to a story by The Verge. Reports indicate that the technology has been ready for a while, but Google delayed it until Apple implemented tracking protections into iOS to address stalking concerns. To that end, both companies announced a partnership last year to develop industry standards to fight the misuse of tracking devices. Apple applied updated protections against stalking in iOS 17.5, which is still in beta. 

The GoPro Hero 12 already had the promise of a better battery life than its predecessors. When you toss a battery grip into the mix, the company says you'll get over five hours of continuous 4K recording at 30 frames per second (depending on conditions). That's bound to be pretty enticing for those who like to capture as much footage as they can during a day of action sports or travel vlogging. What's even better is that a bundle of the camera and battery grip is on sale for $499 at Amazon and GoPro directly. The bundle is $100 off the regular price and a record low.

Along with 4K footage, you can film in HDR at a resolution of 5.3K at up to 60 frames per second. You can shoot in 4K at up to 120 fps too, while there's 10-bit color support. A vertical capture feature makes it a cinch to shoot footage for apps like TikTok even while the camera is in a horizontal orientation.

GoPro's stabilization tech is in full force here as well, with the company claiming HyperSmooth 6.0 can give you "impossibly smooth footage no matter how rough it gets." A horizon lock option should keep the horizon steady as you move the camera.

There's directional audio support thanks to the microphone on the included Media Mod, which has a 3.5mm mic port and micro HDMI port too. You can also connect AirPods, Bluetooth earbuds and wireless microphones to the camera and even use voice commands..

The battery grip affords you single-hand control over the camera. It has a built-in tripod and you can remove it to operate the GoPro Hero 12 remotely from up to 30 meters (98 feet) away. Along with the battery grip and Media Mod, the bundle includes a self-explanatory Light Mod and Enduro Battery.

If you want a solid but small portable game console to play as you travel around (or comfortably sit in bed), then you're in luck as our pick for best handheld gaming console for commuting is currently on sale. The Nintendo Switch Lite is discounted to $179, down from $200 — and it comes with Animal Crossing: New Horizons. This sale at Walmart brings the bundle to a record-low price.

The Nintendo Switch Lite came out in 2019, and we gave it a 90 in our review. As the name suggests, it's lightweight and more comfortable to hold than the bulkier Switch. The Switch Lite has a 5.5-inch screen, compared to the regular Switch's 6.2-inch, and both have a 720p display. It also offers four hours and 15 minutes of continual use before the battery life runs out.

Animal Crossing: New Horizons is all about creating a new civilization right on a deserted island. You can make your own "island paradise" and slowly build a relaxed world for yourself. Plus, the Switch Lite has a Timmy and Tommy Aloha theme to go with the game. A new Switch is rumored to drop in 2025, but this sale is a good opportunity if you've yet to pick one up or need a good gift for someone.

Apple, in its latest update to its App Store developer guidelines for iPhones and iPads, flagged by 9to5Mac, says it will allow game console emulators – and even downloadable games.

Apple warns developers, however, they “are responsible for all such software offered in [their] app, including ensuring that such software complies with these Guidelines and all applicable laws.” So don’t expect to play Super Mario, Spyro, or a third game series that starts with an 'S'.

Meanwhile, we have a guide to watching (and recording) the total eclipse in North America later today. The best chance of good viewing along the path of eclipse totality is still in northeastern parts of the US (Buffalo, NY, Burlington, VT) and southeast Canada (Niagara Falls and Montreal).

OpenAI and Google may have transcribed YouTube videos to train their AI models

If so, they violated YouTube creators’ copyrights.

OpenAI and Google trained their AI models using text transcribed from YouTube videos, potentially violating creators’ copyrights, according to a report from The New York Times. The report centers on how OpenAI, Google and Meta have attempted to maximize the data they can feed to their AIs and cites numerous people with knowledge of the companies’ practices.

Not that these companies relied on the auto-generated (hit-and-miss) auto-transcriptions provided by YouTube itself. Reportedly, OpenAI used its Whisper speech recognition tool to transcribe more than a million hours of YouTube videos to train GPT-4. The report, however, claims people at Google knew but did not act — because Google was doing the same to train its own AI models. Google told NYT it only uses video content from creators who have agreed to it.

Tesla will unveil a robotaxi on August 8

Musk made the announcement on X.

Hours after Reuters published a report about the automaker scrapping its plans to produce a low-cost EV, Tesla boss Elon Musk took to X to say the company would unveil a robotaxi on August 8. The same report said Musk’s directive was to “go all in” on robotaxis built on the company’s small-vehicle platform.

In response to the report, the Tesla chief tweeted “Reuters is lying (again).” Given he confirmed the robotaxi plans, he could have meant a more affordable Tesla EV was still on the table, at least for now.

One of these concept lunar vehicles could join NASA’s next moon mission

Three companies are in the running.

NASA

Three companies are pitching lunar vehicle designs to support NASA’s upcoming Artemis missions. The space agency announced this week that it’s chosen Intuitive Machines, Lunar Outpost and Venturi Astrolab to develop their lunar terrain vehicles (LTV) in a feasibility study over the next year. The LTV will need to function as both a crewed and uncrewed vehicle, serving sometimes as a mode of transportation for astronauts and other times as a remotely operated explorer. NASA says it’ll contract the chosen vehicle for lunar services through 2039. Take a look at the options.

Spotify is following the lead of many companies over the last year and dipping its toe into the world of AI prompts. The platform has announced AI Playlist, a new beta feature that lets you create playlists with a few words that get into the music vibe you want, such as "an indie folk playlist to give my brain a big warm hug." 

According to Spotify, the AI playlist will accept prompts involving things like animals, movie characters, colors, places, activities and emojis. Examples from Spotify include everything from "sad music for painting dying flowers" to "relaxing music to tide me over during allergy season." It recommends using a mix of characteristics in your prompt to create the ideal playlist for your vibe. 

The AI Playlist beta is available to Premium subscribers on Android and iOS devices in the United Kingdom and Australia. If you fall into that group, access it through the "+" button in the top right of your library. Click AI Playlist and choose an existing prompt or create your own. Spotify will create the playlist, and you can preview it, delete tracks, and provide notes. Once you're happy, click Create, which will save to your library. 

Spotify's AI Playlist comes over a year after Spotify unveiled its AI DJ, which pulls together a selection of music you're currently listening to, previously played and songs it thinks you'll like based on your history. If the songs playing aren't precisely what you're in the mood for, then you can ask the DJ to switch things up. 

Three companies are vying for the opportunity to send their own lunar vehicle to the moon to support NASA’s upcoming Artemis missions. The space agency announced this week that it’s chosen Intuitive Machines, Lunar Outpost and Venturi Astrolab to develop their lunar terrain vehicles (LTV) in a feasibility study over the next year. After that, only one is expected to be selected for a demonstration mission, in which the vehicle will be completed and sent to the moon for performance and safety tests. NASA is planning to use the LTV starting with the Artemis V crew that’s projected to launch in early 2030.

The LTV that eventually heads to the moon’s south pole needs to function as both a crewed and uncrewed vehicle, serving sometimes as a mode of transportation for astronauts and other times as a remotely operated explorer. NASA says it’ll contract the chosen vehicle for lunar services through 2039, with all the task orders relating to the LTV amounting to a potential value of up to $4.6 billion. The selected company will also be able to use its LTV for commercial activities in its down time.

Lunar Outpost

Astrolab

Intuitive Machines, which will be developing an LTV called the Moon Racer, has already bagged multiple contracts with NASA as part of the Commercial Lunar Payload Services (CLPS) program, and in February launched its first lander, Odysseus, to the moon to achieve the first commercial moon landing. Venturi Astrolab will be developing a vehicle it’s dubbed Flex, while Lunar Outpost will be working on an LTV called Lunar Dawn. All must be able to support a crew of two astronauts and withstand the extreme conditions of the lunar south pole. 

 “We will use the LTV to travel to locations we might not otherwise be able to reach on foot, increasing our ability to explore and make new scientific discoveries,” said Jacob Bleacher, a chief exploration scientist at NASA.

Apple’s second-generation AirPods Pro have dipped to under $200 in a deal from Amazon. The AirPods Pro, which normally cost $250, are $60 off right now, bringing the price down to just $190. That’s the same price we saw during Amazon’s Big Spring Sale. The AirPods Pro offer a number of premium features over the standard AirPods, including active noise cancellation for when you want to shut out the world, and an impressive transparency mode for when you want to hear your surroundings.

The second-generation AirPods Pro came out in 2022 and brought Apple’s H2 chip to the earbuds for a notable performance boost. It offers Adaptive Audio, which will automatically switch between Active Noise Cancellation and Transparency Mode based on what’s going on around you. With Conversation Awareness, they can lower the volume when you’re speaking and make it so other people's voices are easier to hear.

We gave this version of the AirPods Pro a review score of 88, and it’s one of our picks for the best wireless earbuds on the market. The second-generation AirPods Pro are dust, sweat and water resistant, so they should hold up well for workouts, and they achieve better battery life than the previous generation. They can get about six hours of battery life with features like ANC enabled, and that goes up to as much as 30 hours with the charging case. Apple says popping the AirPods Pro in the case for 5 minutes will give you an hour of additional listening or talking time.

AirPods Pro also offer Personalized Spatial Audio with head tracking for more immersive listening while you’re watching TV or movies. The gesture controls that were introduced with this generation of the earbuds might take some getting used to, though. With AirPods Pro, you can adjust the volume by swiping the touch control.

Geek Squad agents have been flooding Reddit with images of their badges and posts about “going sleeper” after the company reportedly conducted mass layoffs this week. A former employee who spoke to 404 Media said they were sent an email notifying them to work from home on Wednesday and were then called individually to be told the news about their jobs. Some, per 404 Media’s sources and numerous Reddit posts, were longtime Geek Squad agents who had been with the company for more than 10 or even 20 years. Best Buy has not yet responded to Engadget’s request for comment.

There has been an outpouring of support for the laid off workers on the unofficial Geek Squad subreddit, where many have lamented the loss of jobs they’d dedicated much of their lives to and noted that things in the lead up had been heading in a concerning direction. Some commented that their hours had dwindled in recent months, with one former employee telling 404 Media it’s been “a struggle to get by.”

Best Buy conducted mass layoffs affecting employees at its retail stores just last spring, and as The Verge reports, CEO Corie Barry indicated during the company’s February earnings call that more layoffs were coming in 2024 as Best Buy shifts resources toward AI and other areas.

OpenAI and Google trained their AI models on text transcribed from YouTube videos, potentially violating creators’ copyrights, according to The New York Times. The report, which describes the lengths OpenAI, Google and Meta have gone to in order to maximize the amount of data they can feed to their AIs, cites numerous people with knowledge of the companies’ practices. It comes just days after YouTube CEO Neal Mohan said in an interview with Bloomberg Originals that OpenAI’s alleged use of YouTube videos to train its new text-to-video generator, Sora, would go against the platform’s policies.

According to the NYT, OpenAI used its Whisper speech recognition tool to transcribe more than one million hours of YouTube videos, which were then used to train GPT-4. The Information previously reported that OpenAI had used YouTube videos and podcasts to train the two AI systems. OpenAI president Greg Brockman was reportedly among the people on this team. Per Google’s rules, “unauthorized scraping or downloading of YouTube content” is not allowed, Matt Bryant, a spokesperson for Google, told NYT, also saying that the company was unaware of any such use by OpenAI.

The report, however, claims there were people at Google who knew but did not take action against OpenAI because Google was using YouTube videos to train its own AI models. Google told NYT it only does so with videos from creators who have agreed to take part in an experimental program. Engadget has reached out to Google and OpenAI for comment.

The NYT report also claims Google tweaked its privacy policy in June 2022 to more broadly cover its use of publicly available content, including Google Docs and Google Sheets, to train its AI models and products. Bryant told NYT that this is only done with the permission of users who opt into Google’s experimental features, and that the company “did not start training on additional types of data based on this language change.”
