Lowe’s Recalls Over 500,000 Kobalt Yard Tools Over USB-C Battery Fire Risk

Published

on





Product recalls are fairly common among power tool brands, with some affecting millions of products. Kobalt, the in-house power tool brand owned by Lowe’s, has become the latest company to announce a massive recall that affects more than 550,000 individual products. The staggering number of affected products (554,780, to be precise) qualifies this to enter the list of some of the biggest product recalls ever issued by power tool manufacturers in the U.S. The products affected by this recall were all manufactured by Greenworks for Lowe’s and include USB-C powered 24V and 48V trimmers, blowers, chainsaws, and pruning saws.

According to the official recall notice issued by Greenworks on the Consumer Product Safety Commission (CPSC) website, the issue came to light after Greenworks received more than 30 instances of the batteries used in these products releasing smoke, emitting sparks, and catching fire. The company also noticed that in all the instances, the affected battery was placed inside the tool’s battery compartment and was being charged using a USB-C cable. No injuries or property damage were reported.

Because the issue is caused by the Lithium-ion battery, Greenworks has confirmed that it will replace the batteries affected by this issue for free. Until the replacement happens, the company recommends that users stop charging them using USB-C cables while inserted inside the power tools.

What products are affected by the recall?

Greenworks has confirmed that the affected batteries, when charged using USB-C cables, show a tendency to short circuit, which in turn leads to the possibility of injury due to a fire hazard. As outlined earlier, only products that can be charged via USB-C are affected by this issue. The affected batteries come in various sizes, including 3.0Ah, 4.0Ah, 5.0Ah, 6.0Ah, and 8.0Ah. Of these, 6.0Ah and 3.0Ah batteries were also sold separately.

The products affected by this battery issue include Kobalt-branded String Trimmers, Deck Push Mower Kits, Deck Self-Propelled Mower Kits, Chainsaw Kits, Pruning Saw Kits, Blower Kits, and Bristle Brush Kits. All of these affected products were sold between January 2026 through May 2026 at Lowe’s stores across the U.S, as well as the Lowes website. The products span a wide price bracket, ranging from $20 to $482. Greenworks has published the entire list of the products affected by the issue.

If you own a Kobalt yard tool affected by this recall, you’ll need to complete an online registration form to begin the process. Once your eligibility is verified, Greenworks will send you a free replacement lithium-ion battery rather than replacing the entire tool. The company will also provide instructions and a prepaid shipping label for returning the affected battery at no cost.

Grok Build was uploading entire Git repositories to xAI’s cloud, including committed secrets

Published

on

A security researcher published a wire-level analysis on July 12 proving that xAI’s Grok Build coding CLI was packaging developers’ entire tracked repositories, including full Git history, committed secrets, and API keys, and sending them to a Google Cloud Storage bucket. The upload volume was roughly 27,800 times greater than the data the coding task actually required, according to the analysis.

The researcher, publishing as cereblab, tested version 0.2.93 of Grok Build, intercepted the upload, cloned the git bundle from the captured request, and recovered a file the AI agent had been explicitly told not to open. xAI had marketed the tool with claims that “nothing from your codebase transmitted to xAI servers during a session.” The wire data directly contradicts this.

The privacy toggle that was supposed to prevent data transmission did nothing, according to multiple reports. Grok has a history of privacy issues, including training on X user data without consent in what regulators called a “very likely” breach of EU law. A quarter of European firms have banned Grok entirely in favour of alternatives with better security controls.

Elon Musk confirmed the uploads and said SpaceXAI would delete all prior Grok Build user data. The company documented a “zero data retention” policy and added a /privacy endpoint. A same-client retest observed a server-side flag disabling the uploads. However, no independent audit has confirmed the deletion. Grok Build launched alongside Grok 4.5 as xAI’s answer to Claude Code and Cursor, making the privacy breach particularly damaging for a product positioned to win enterprise developer trust.

OpenAI’s First Device Will Be Moveable, Screenless Speaker Built as AI Companion

Published

on

OpenAI is reportedly developing a screen-free, portable smart speaker meant to act as a personalized home computer and humanlike AI companion. “It will help control smart-home appliances, play media, answer questions, respond to messages and tap into the range of capabilities offered by OpenAI’s ChatGPT,” reports Bloomberg, citing people familiar with the matter. The device, expected to be unveiled this year and released in 2027, would mark OpenAI’s first major hardware push after acquiring Jony Ive’s io Products. Bloomberg reports: Apple sued OpenAI last week, accusing the company of stealing trade secrets. But OpenAI believes that the device veers significantly from anything Apple has on the market today and that it’s unlikely that it violates trade secrets belonging to the iPhone maker, the people said. OpenAI’s success in hardware will hinge on bringing a novel approach to the market — something it aims to do with the smart speaker. For instance, the device’s technology is meant to become increasingly personalized and proactive as it gains a deeper understanding of its owner over time, according to the people.

OpenAI envisions the device anticipating needs, surfacing information proactively and serving as an expert on its user, they said. Though the speaker is designed to stay in the home, it will be easy to move around the house. OpenAI believes the product’s defining feature will be its personality and ability to connect on a humanlike level with users. The speaker incorporates mechanical elements that can move on their own, creating a sense that it is alive and not just an object responding to commands. The machine also will draw on personal information such as emails to better understand its owner. The goal is for the device to feel like a companion and become a physical manifestation of OpenAI’s ChatGPT. Still, the exact plans could change as the company works through the development and legal process.

The device’s communication abilities will rely on a more advanced version of the ChatGPT Voice Mode — GPT-Live — that OpenAI rolled out this month. The new voice mode is designed to act more like a human. It can listen and talk at the same time, adapt more naturally during conversations, and quickly process information. Though the new product resembles a speaker, OpenAI internally describes it as the first of its kind: a computer built for AI to help make busy people more productive. It includes a camera and other sensors that help it understand a user’s surroundings and context, as well as advanced AI models beyond those available on conventional smart speakers. Another central difference is that the device includes a rechargeable battery, allowing it to be carried from room to room throughout the day. A user could bring it into the laundry room while doing chores, move it into the kitchen for cooking assistance, and later place it in a living room or bedroom to have it play music. It can also remain plugged into a single room if the customer chooses.

4 Essential Tools Homeowners Need For DIY Roof Repairs

Published

on





We may receive a commission on purchases made from links.

Hiring a professional to do work around the house is convenient, but it can get expensive. Thus, the DIY option may seem enticing. Some jobs are more daunting than others, though, and one of the more challenging is likely fixing up the roof — not just because it requires you to climb. After all, the last thing you want is to damage the roof or make things worse, so stocking up on the correct tools for the job is the first big hurdle to conquer. 

Advertisement

Smaller repairs generally won’t require large or expensive tools. For the most part, you’ll only need tools to remove worn or damaged parts and install their replacements. If you need to do anything more than that, it’s probably better to leave the repairs to professionals. Structural repairs aren’t for novices, and given how essential a functioning roof is, it’s fair to say extensive roof repairs are among the DIY projects you should never try to do yourself.

With that said, there’s no shame in learning something new and making some minor fixes to your roof. These are some essential tools you’ll want for DIY roof repairs.

Extension ladder

No matter what the task at hand is, if you need to get on the roof, you’ll need a good ladder. An extension ladder is generally the way to go for roof repair, as it leans and stabilizes itself against the gutter. Step ladders, while must-own home improvement gadgets, are likely to wobble and tip, becoming a life-threatening hazard in short order. Besides, an extension ladder is a sound investment even if you don’t plan to make a habit of repairing rooftops. The height and stability they offer can help with everything from repairing upstairs windows to trimming tree branches.

When shopping for an extension ladder, there are a few things to consider. You’ll, of course, want one tall enough to reach your roof. The material is key, too; if you want to stay safe and avoid any potential issues with power lines, a ladder made from non-conductive fiberglass is the way to go. Unfortunately, sturdy fiberglass extension ladders do get expensive: A Werner 16-foot Fiberglass Extension Ladder costs $300, for example. But the combination of safety, functionality, and versatility they offer makes it a small price to pay.

Pry bar

If you need to repair or patch a roof that’s falling apart, you’ll need to remove the damaged material first. You may be able to remove loose shingles by hand, but a quality pry bar will make the whole process much easier. A good one will also help tremendously when removing old roofing nails and be useful for a host of other DIY tasks as well, making it a versatile buy. Fortunately, this isn’t a complicated tool, nor will it break the bank.

There’s no shortage of pry bars on the market, and most quality ones aren’t all that expensive. For example, the Stanley Wonder Bar II retails for just $4.99 at Home Depot, while the Milwaukee 15-inch Pry Bar is pricier but still affordable at $16.97. If you want to spend a bit more, though, there are designated shingle removal tools to consider. These operate similarly to traditional pry bars but are specifically designed to get below roof shingles and lift them. Examples of this include the $53.30 Guardian Fall Protection 54-inch shingle remover and the $24.98 24-inch Husky Mini shingle roof shovel.

Roofing hammer

Once you’ve removed the old shingles and nails, it’s time to install replacements. A good roofing nailer is an option, but you could also consider a roofing hammer instead, especially for small-scale work. Not only can you use them to drive in and remove roof nails, but they can also cut shingles and underlayment material down to size, eliminating the need for another tool.

Naturally, there’s an argument that a roofing nailer is the superior tool. While these power tools are quicker and more effective at nailing material into rooftops, though, they have downsides for the DIYer that make them a potentially inferior choice. The main issue is that they’re bulkier tools that may be hard to use, especially for the inexperienced. You’ll also need supporting equipment, such as an air compressor or a battery and chargers, making them an even bigger investment and more cumbersome to set up. On top of all of this, they’re more expensive on their own. Nailers rarely dip below $100, with most models costing multiple hundreds of dollars. Meanwhile, roofing hammers like the Crescent 28-ounce Steel Shingler Hammer can be had for under $40.

Caulk gun

Shingles are great for keeping the weather out, but there are times when you’ll need to use sealant as well, be it for waterproofing or filling cracks. That’s where a caulk gun can come in handy. There are several major electric caulk gun brands out there, which are great choices if you’ve already bought into their battery systems and expect to use such a tool regularly. However, they might be overkill for those who only plan to use them occasionally — and, crucially, don’t want to spend a ton of money. In that case, a manual caulk gun is a cheap yet effective alternative. There’s an Anvil caulk gun for $5.98 at Home Depot or the $4.99 Project Source caulking gun at Harbor Freight, for example.

Caul guns can come in handy for other home DIY projects, too. These tools are excellent for sealing cracks around window frames, waterproofing bathtubs and showers, repairing concrete, and more. If you’re going down this route, you may be able to justify the higher price of an electric model. These can start as low as the $40 20-volt Bauer caulk gun from Harbor Freight and go up to the Milwaukee M18 electric caulk gun, which retails for $299.00 at Home Depot.

How we selected these tools

The first step in selecting these tools was determining the scope of DIY roofing work itself. We defined the limits of such work as anything outside of full-on roof replacement and structural repair — both of which demand extensive roofing knowledge and a serious arsenal of high-end tools. All of this helped narrow the field, but this was only the start, and more filtering was needed to come up with the final list.

From here, we settled on a few key criteria that tools had to fit. We wanted to focus on tools that the average DIY-capable homeowner could use; thus, they had to be easy to use, safe, or both. We also decided to focus on reasonably affordable tools, since the goal was to have a selection of somewhat entry-level suggestions for roofing newcomers. Similarly, we made sure to choose tools that could be used for other DIY jobs beyond roofing. This way, a potential buyer can get more use from their tools.

Full Body VR Tracking Is Just Some Recycled Hardware Away

Published

on

Full body tracking in VR applications involves attaching sensors to one’s body, and [Jaki] has a DIY method to do it on the cheap: the Vive Tracker Lite project repurposes Vive controllers as lighthouse-based trackers, no hardware modifications required.

A common method of doing body tracking is to strap on some Vive trackers. Those are extremely hacker-friendly pieces of hardware, but [Jaki] observed that older Vive VR controllers can be had for cheap, and already contain everything a tracker needs. Some new firmware and a custom mount is all it takes to turn them into perfectly usable body trackers.

But what about a wireless receiver? [Jaki] has that covered as well with the $5 Viva Dongle, which uses a Pro Micro NRF52840 to act as a cheap DIY alternative to the official dongle hardware.

We appreciate the effort put into making this project accessible to everyone, even novices. [Jaki]’s put effort into a Python program with a full GUI to make the flashing of firmware as easy as possible for both projects. Experimenting with body tracking in VRChat or games with mods is just some recycled hardware away.

Granted, a Vive controller is not the slimmest piece of hardware, but all it takes is a firmware change and a 3D-printed fixture to make a perfectly serviceable tracker. That being said, we’re sure an enterprising hardware hacker may crack a controller open and embark on a serious rebuild, or even interface to some of the inputs in a clever way. If you’ve done that or know of someone who has, drop us a note on our tips line because we’d love to see it.

Is Overnight Charging Killing Your Smartphone’s Battery?

Published

on





How long your smartphone lasts on a full charge is important, especially if you know you’re going to be away from a charger for a while. Despite massive improvements in battery technology, one of the most common myths about charging is that leaving your phone plugged in overnight will damage its battery. This is simply not true.

Modern phones come with smart chips that regulate how much power the battery receives. As your phone nears 100% battery, charging speeds should be reduced and eventually halted, so it won’t be actively charging. Power is drawn in short bursts when your phone loses a few percentage points. Samsung calls these “maintenance charges” and says there’s no risk of overcharging although it does note the small caveat that unplugging at 100% can marginally extend battery lifespan.

Lithium-ion cells indeed last the longest when they spend less time at very high or very low levels of charge — this is where the 20-80 rule in charging comes from. Many manufacturers, like Apple and Samsung, therefore let you turn on an optimized charging option of sorts that’s designed for overnight charging sessions. On iPhones, the feature pauses charging at 80% and finishes topping up shortly before you typically wake, while Samsung’s version offers modes that either cap the charge at 80% or adapt to your sleep schedule. The feature may be labeled a bit differently depending on which smartphone you own.

How to optimize battery degradation

To maximize battery life, you could religiously follow the 20-80 rule — but at this point, you’re effectively only using 60% of your phone’s battery. Some smartphones even let you set charging limits, helping make sure that your phone never exceeds, say, 80% even when plugged in overnight. Regardless, one factor that definitely damages the battery is heat, so avoid charging your phone in hot weather. Apple claims charging your device in temperatures higher than 95 degrees Fahrenheit could negatively impact its battery health.

Gaming-centric smartphones often go through their battery charge quickly, but there’s one way to ease the strain: bypass charging. If your device supports it, this feature powers the phone directly from your charging brick and lets your battery rest. 

Advertisement

There’s also the myth that charging your phone with a stronger charger will destroy its battery. This is, once again, not true. The battery controller chip only lets in as much wattage as the phone is designed to accept. That said, sticking with a compatible charger will ensure your phone charges at its maximum rated speed.

Ultimately, battery degradation depends on the charge cycle count. You can change various settings to extend your phone’s battery life on both iPhones and Android devices. This will, in turn, reduce the number of full charge cycles your battery goes through over time.

Anthropic commits $10 million to Canadian AI research across eight institutions

Published

on

TL;DR

Anthropic committed $10M CAD to eight Canadian institutions for AI research. Canada ranks second globally in per-capita Claude usage. Startups get $5K API credits.

Anthropic is committing $10 million CAD to eight Canadian research institutions to fund work on beneficial and responsible AI applications. The partnerships span Canada’s three leading regional AI institutes, Amii in Edmonton, Mila in Montréal, and the Vector Institute in Toronto, along with children’s hospital CHEO, the Centre for Addiction and Mental Health, Université Laval, the University of Toronto, and the University of Saskatchewan.

The funding covers research areas from reinforcement learning and AI safety to mental health, Indigenous languages, and quantum computing. Mila will use Claude to develop AI assistants that help researchers discover and assess scientific breakthroughs. CAMH’s Krembil Centre for Neuroinformatics will build predictive models for mental health treatment and run fairness evaluations of psychiatric AI systems. Université Laval will study how large language models behave in varied cultural contexts, including Quebec French and Indigenous languages.

Anthropic also published its first Canadian country brief from the Anthropic Economic Index. Canada ranks eighth worldwide in Claude usage but second in per-capita adoption, with Canadians using Claude at more than four times the rate their population predicts. Only the US ranks higher. Usage tracks the local economy: translation requests are highest in provinces with more government workers, reflecting Canada’s bilingualism requirements. British Columbia leads in per-person use, with Ontario close behind. Anthropic committed $200 million to a Gates Foundation partnership in May, and the Canadian investment extends the company’s pattern of building non-commercial relationships alongside its enterprise business.

TechIreland names Niall Norton new chief executive officer

Published

on

The nonprofit organisation said it aims to deepen its role as Ireland’s independent source of ecosystem data and help build the country’s leadership position in AI transformation.

Irish nonprofit organisation TechIreland has appointed Niall Norton as its new chief executive officer, replacing interim CEO John O’Dea.

TechIreland gathers and shares data intelligence around the Irish technology ecosystem by tracking more than 14,500 companies, including start-ups, scale-ups, investors, multinationals and support organisations.

It said the appointment comes at a time when the organisation is aiming to deepen its role as Ireland’s independent source of ecosystem data and help build the country’s leadership position in AI transformation.

“The technology ecosystem has multiple stakeholders, all of whom have a vested interest in its success: the start-up and scale-up companies themselves, the Government and State bodies, the investors, the multinational partners, the innovation hubs and the professional services firms,” said Norton.

“All successful technology ecosystems track measures, activity, health and performance of the ecosystem in order for stakeholders to work together effectively. The curation of transparent, reliable and available data in the service of all of these entities is a key element to promoting success.

“TechIreland has done a great job providing this essential curation service that is needed now more than ever. I look forward to working with our partners in the industry to promote Ireland as a location for valuable, sustainable jobs.”

Norton was previously chief financial officer at O2 Ireland and chief executive of Openet, a Dublin-headquartered telecoms software company that began as a start-up before being acquired by Amdocs in 2020.

Brian Caulfield, board director of TechIreland, said: “TechIreland is a crucial piece of national infrastructure for Ireland’s technology ecosystem. As such, it’s great to be able to welcome such a seasoned and successful leader as Niall as CEO. I look forward to working with Niall to continue and enhance the organisation’s mission.”

Norton is a fellow of the Institute of Chartered Accountants in Ireland, holds a certificate in management excellence from Harvard Business School, and has recently completed a programme in software development with the UCD Professional Academy.

At the end of May, TechIreland published its Irish Start-up Funding Review for 2026, a report covering start-up fundraising activity in Ireland in 2025.

Caulfield said at the time: “2025 was very much a curate’s egg. It was good in parts – mainly in Q1, when 69 Irish companies raised a total of €616m. That was the best quarter for fundraising in Ireland for 10 years.

“Unfortunately, the rest of the year saw a return to weakness, with just €376m raised by 250 companies across the rest of the year. Once again, just four outliers represented almost half of all funding (46pc). More widely, the pattern of Irish companies being underfunded relative to international competitors remains a worry.”

In March, the nonprofit released its Female Founder Funding Review 2026, which tracked investment into women-founded start-ups throughout 2025.

The report found that last year, 82 Irish start-ups led by women raised a total of €131m, representing the highest number of women-founded start-ups funded in any given year.

Lorde says AI glasses are “not sexy”

Published

on

While Kylie Jenner serves as a human billboard for Meta’s AI glasses, pop star Lorde isn’t buying it.

During a set at the Mad Cool Festival in Madrid last week, Lorde had some choice words about the new technology, which many security experts have deemed a privacy nightmare.

“Increasingly in our world, it gets harder and harder to know what is real,” Lorde told the audience. “You don’t know if someone is wearing sunglasses, or if they’re wearing those f–ed up, f–ing [AI glasses]. Can I just say, for the record, f— the glasses. Don’t get the glasses. Not sexy.”

Lorde has written before about throwing her phone into the ocean, but this was next level.

Advertisement

Lorde was possibly moved to comment on the latest trends in tech because Ray-Ban, a sponsor of the festival, partners with Meta to make AI glasses. Lorde also performed immediately before the singer Jennie, who is an ambassador for Ray-Ban x Meta’s smart glasses line.

Lorde isn’t alone in raising concerns. Smart glasses, which come with cameras and AI features, have been used as tools for harassment and extortion. Meta, the most popular smart glasses maker, has said it takes privacy seriously and builds in safeguards like a visible recording light, but the company is facing many investigations and lawsuits alleging privacy violations. One lawsuit alleges that Kenyan contract workers were made to watch graphic videos obtained with the glasses to help train Meta’s AI. (Meta hasn’t publicly detailed its response to that specific claim.)

Advertisement

None of this has stopped the product from strong sales. EssilorLuxottica, the Ray-Ban maker, said it sold more than 7 million Meta AI glasses in 2025 — more than triple the roughly 2 million units it sold in 2023 and 2024 combined. Ray-Ban Meta glasses have been such a hit in the smart-glasses category that an emboldened Meta keeps expanding the lineup.

But hey, if privacy doesn’t make people think twice about the glasses, maybe vanity will. Lorde nails it pretty concisely with her declaration that they’re simply “not sexy.”

The here and now, she added, now that “is sexy.”
