Makers assembled a compact handheld unit that listens to standard wireless network signals and converts subtle shifts in those signals into a real-time radar display of nearby human activity. The entire system fits comfortably in one hand and comes together for roughly fifty dollars in parts. Movement registers even when walls or other barriers stand between the device and the person. No camera, no infrared sensor, and no dedicated motion detector appears anywhere in the build. Instead the unit taps into Channel State Information (CSI) carried by ordinary Wi-Fi traffic in most homes and offices.

CSI contains a wealth of information on signal intensity and phase across several sub-channels, acting as a unique fingerprint that is written into the air by every surface, item, and person in its vicinity. Then there’s human tissue, where the water reacts with radio waves in a way that makes it stand out from everything else in the room. Of course, motion alters this distinct pattern, allowing the device to detect it. After calibrating the device with a quick empty room scan, the firmware can set a baseline and compare new data to it. Any continuous changes that exceed a specific threshold will trigger a detection and leave a mark on the radar display. One processing core is constantly collecting data, while the other maintains the screens responsive, with no lag.

Building it all begins with an M5Stack Cardputer ADV board, which already has an ESP32-S3 microcontroller, a small screen, a keyboard, and a battery. Then you simply slap an extra display onto the board and place it in a simple 3D printed frame above the primary unit, and you’re ready to go. Dual displays are no problem, and because it reuses existing Wi-Fi networks rather than creating its own, the parts list is kept to a minimum.

When it first powers up, it scans for available networks; select one, input your password, and you’re ready to go. Connection is confined to the networks you manage, which prevents the unit from spying on other people’s traffic. Once the connection is established, the radar activates and the smaller screen displays all connection details, a scrolling graph of recent activity, and options such as a clear or presence banner, as well as the sensitivity setting. The larger screen displays the real radar image, which is a sweep line slowly traveling across a circular view with fading trails indicating where earlier movements were identified, and as the marks emerge, they grow or shrink depending on how much the signals shifted at the time.

Of course, there are keyboard shortcuts for things like triggering a fresh calibration, adjusting the detection threshold, and navigating to the settings menu. The entire machine can run totally on battery power or a USB connection when necessary, and because it just uses Wi-Fi signals that are already floating around, it can work in the dark and through most interior walls. With some furniture around, readings can be thrown off as reflections bounce off everything, causing your gadget to go berserk, but with careful positioning and tweaks, you can generally keep the false triggers under control. The problem is that the current design just provides you a general sense of movement in the area and does not provide precise direction or distance.

Because the code, build files, and enclosure designs are now public on Github, anybody can recreate or adapt the project to meet their own requirements. The same Wi-Fi signals that make life so convenient also allow you to utilize this device to determine whether anyone is in the room or if there’s any unusual activity going on someplace. As a result, it has a variety of helpful uses, such as automatic lighting control when you enter a room and simple notifications when someone does something unexpected. The only issue is attempting to completely avoid using it without blocking Wi-Fi connections.

Glasgow-headquartered FullProxy provides cyber consultancy services to public and private sector organisations across the UK.

Irish telecoms and IT company Viatel Technology Group has acquired Scottish cybersecurity consultancy FullProxy for an undisclosed amount.

The acquisition – which is backed by investment from Macquarie Capital – is designed to expand Viatel’s presence in the UK and its cyber capabilities, according to the company.

FullProxy was founded in 2015 by CEO Ewan Ferguson and CTO Chris Templeton and provides cyber consultancy services to public and private sector organisations across the UK.

The company, which is headquartered in Glasgow, has particular expertise in network design and implementation, cloud authentication and endpoint security, and counts customers in data-sensitive sectors such as healthcare, local government, financial services and critical infrastructure with clients including the NHS, Scottish government, Virgin Money and FNZ.

As well as being recognised as an Expert Fortinet Partner and elite F5 Gold Tier partner, FullProxy has also been featured in TechUK’s Tech200 Growing Companies, and shortlisted twice for Scottish Cyber Security Company of the Year at the Scottish Cyber Awards.

“Over the last decade we’ve built FullProxy around a deeply felt principle: helping customers solve complex cybersecurity challenges and achieve ROI through expert advice, deep technical capability and long-term trusted relationships,” said Ferguson. “The growth we’ve achieved in recent years is a testament to the quality of our people, the trust of our customers and the strength of our partnerships. We are incredibly proud of what the team has built.

“Joining Viatel gives us the opportunity to build on that success.”

Viatel said the acquisition will further strengthen its “core cybersecurity capabilities” at a time when organisations are under growing pressure to secure complex digital infrastructure while preparing for wider AI deployment.

“As clients adopt AI and manage increasingly complex digital estates, the need for deep cybersecurity expertise has become more urgent,” said Paul Rellis, CEO of Viatel Technology Group. “FullProxy strengthens our position as an integrated technology partner with expertise across security, networking and digital services and enhances our ability to deliver solutions that are aligned to customer priorities.

“It also represents a strong endorsement of our cyber division and our long-term strategy to help organisations build resilience today and grow securely for the future.”

FullProxy is the latest in a series of tech companies to be acquired by Viatel in recent years.

Last year, the company acquired the Belfast-based cyber operations of UK IT services firm Cybit.

In 2024, Viatel acquired the technology division of managed print services provider MJ Flood in a deal reportedly valued at €30m, while in 2023, it snapped up US-headquartered cloud-connected infrastructure provider Sungard Availability Services – its eighth acquisition since 2020.

Its other acquisitions include Wifiber, Nova Telecom, Irish Telecom, SupportIT and Action Point.

Nvidia competitor Etched announced this week that TSMC had manufactured its first chip earlier this year. While the four-year-old startup valued at $5 billion is getting ready to ship systems powered by that chip to customers later this summer, scaling production may prove challenging. Like other chip designers, Etched must compete for limited capacity at TSMC’s Taiwan factories.

Copper Sky Capital, one of Etched’s early investors, is hopeful that the chipmaker will find a solution to its manufacturing constraints by eventually producing chips at Arizona’s TSMC facility. When the four-year-old VC firm invested in Etched’s $120 million Series A two years ago, founder Jack Selby secured an allocation in part by promising to help the startup eventually reshore its chip fabrication to Arizona.

Selby, a former PayPal exec and longtime managing director to Peter Thiel’s family office, Thiel Capital, founded Phoenix-based Copper Sky in 2021 (formerly known as AZ-VC). The firm’s first $115 million fund focused primarily on startups based in Arizona and the Southwest. Selby’s thesis was that most coastal startups, particularly those based in California, Massachusetts, and New York, are grossly overpriced compared to companies popping up in his region. However, Selby saw an opportunity to bridge the gap in the other direction by helping California-based hardware startups move their production to Arizona.

Selby credits Copper Sky’s investment in Etched — an otherwise hard-to-access startup — to his influential role in Arizona’s economy. As a board member of the Arizona Commerce Authority, Selby is deeply involved in recruiting out-of-state businesses to set up manufacturing operations in the region.

“When Copper Sky invested with Etched, the company clearly understood our connectivity to the Arizona semiconductor industry, and in particular the local TSMC GIGAFAB,” Selby told TechCrunch.

While Copper Sky has recently expanded its focus beyond the Southwest to include nontraditional venture hubs nationwide, Selby said that the firm is also interested in backing hardware companies, including in the defense sector, that can set up manufacturing operations in Arizona. 

The firm is expected to soon have more capital to invest in those higher-priced coastal companies, and those throughout the United States. Copper Sky is currently raising a $300 million second fund, according to a regulatory filing.

Jon Prosser has formally responded to Apple’s lawsuit over alleged iOS leaks, claiming that he is entirely innocent and that colleague Michael Ramacciotti is solely responsible for any alleged trade secret theft.

Apple’s now year-long case against Prosser had initially seen the YouTuber repeatedly ignoring court deadlines. He began responding in April 2026, and his lawyers have now formally filed his rebuttal to Apple’s accusations that he and Ramacciotti conspired to steal trade secrets from Apple employee Ethan Lipnik.

“Ramacciotti’s is [sic] responsible for all harm caused to Prosser and should indemnify him for all harm caused,” says the filing. “Ramacciotti’s act of displaying the features was not induced by Prosser and, as such, Ramacciotti is completely responsible for the disclosure of Apple’s alleged trade secrets, if any.”

Prosser specifically denies offering money in return for the information Ramacciotti showed him. He also denies knowing how his co-defendant got his information, or conspiring ahead of time to gather it.

Ramacciotti unlocked Lipnik’s iPhone, which had an early release of what was then called iOS 19, and shared confidential details. Prosser claims no knowledge of whose iPhone it was, and denies knowing that Ramacciotti was in the Apple employee’s apartment.

Prosser does admit to sharing with Ramacciotti a portion of the revenue his YouTube video brought in, and said this was to secure exclusivity. “Once Prosser learned how Ramacciotti acquired the proprietary information, he disconnected communication with Ramacciotti,” says the filing.

At one point the filing says that Prosser “has not [sic] knowledge if iOS 19 was in fact ‘unreleased’.” But later it says “Prosser admits that the information was unreleased software.”

That contradictory claim appears to mean that it was during the demonstration of iOS 19 that Prosser did not know it was iOS 19 that he was being shown.

Prosser’s filing, as first spotted by MacRumors, requests trial by jury.

Apple has not responded publicly to the filing.

Separately, Michael Ramacciotti has been cooperating with the courts since at least October 2025, and provided Apple with his emails, computers, and archives. Ramacciotti’s lawyers have claimed that he did not appreciate the value and nature of what he showed Prosser.

Owning a US electric vehicle dealership has been a wild ride in the 2020s.

Since Polestar Short Hills opened in northern New Jersey in 2021, it went through a Covid-era demand spike and EV shortage that left some used electrics with higher valuations than new ones; a new federal tax credit of up to $7,500 that brought a new wave of drivers in the door; lower sales volumes after the rollback of that federal tax credit, and the snipping of a state one; and then another wave of buying when EV-curious drivers began running from Elon Musk’s Tesla because of the CEO’s involvement with the Trump administration.

Now, Matthew Haiken, who owns that Polestar dealership along with three other (non-Polestar) dealerships in the Prestige Collection Auto Group, faces another and more serious challenge. Polestar said in late June that the US Commerce Department had denied an authorization that would have allowed the brand to continue selling cars in the US despite a federal rule restricting the sale of vehicles with Chinese-made connected-vehicle technology. The company, which is majority-owned by China’s Geely Holding and its founder Li Shufu, says it will stop selling Polestar vehicles in the US beginning with the 2027 model year.

“It’s so unfortunate,” Haiken says. “It’s hard for my customers who have been reaching out; it’s hard for my staff.” He says he and the owners of the US’s other 31 Polestar dealerships have invested “many millions” in selling the cars and called the authorization decision “a shock to me and all the dealers.”

Volvo, which is also majority-owned by Geely, received authorization from the Commerce Department in March, allowing it to continue selling its vehicles in the US, despite its Chinese connections. Volvo said at the time that it held “constructive discussions” with the department about the automaker’s “governance, technology and data security.” (When asked about the discrepancy, a Polestar spokesperson said that the company “cannot comment on how legislation applies to other manufacturers.”)

“I am very frustrated in Polestar, globally,” Haiken says. “I think they really dropped the ball, and I blame them. I don’t blame the government.”

The Commerce Department under the Biden Administration officially approved the connected-vehicle rule in January 2025, after government officials argued that a ban on Chinese- and Russian-made automotive hardware and software was necessary for national security reasons. The federal government said that internet-connected automotive cameras, microphones, and GPS equipment threatened US safety. “It doesn’t take much imagination to understand how a foreign adversary with access to this information could pose a serious risk to both our national security and the privacy of US citizens,” Commerce secretary Gina Raimondo said at the time.

The US Commerce Department did not respond to WIRED’s questions.

Polestar said in a statement last week that US dealerships would sell “existing stock” of the Polestar 3 and Polestar 4, and that a US service network would “continue to support customers.” It framed the move as “increasing its strategic focus on Europe,” and said that 94 percent of Polestar’s first quarter 2026 sales took place outside of the US.

Haiken calls that statistic misleading because the brand’s newest offering, the Polestar 4 coupe, went on sale in Europe in January 2024 but wasn’t available in the US until December 2025.

Some Polestar dealerships handle service issues through Volvo centers, but Haiken said his stand-alone Polestar service center will continue fixing and servicing the EVs. “We have the volume to justify it,” he says. “We have to be around to perform that work.” Not all dealerships might make the same decision, he said, though vehicles will likely be sent to the closest service center for tune-ups and fixes.

Report says proposed rewrite gives operators more freedom to shop around for a greener grade

The European Union’s proposed environmental rating system for datacenters may be amended in response to lobbying from IT industry heavyweights, making it easier to offset greenhouse gas emissions using clean energy certificates.

According to the Financial Times, the European Commission is weakening its original proposals after pressure from datacenter operators and tech giants. The newspaper claims to have seen the revised draft of the regulations, set to be discussed by representatives of member states on Thursday.

We asked the Commission for comment on the leaked draft.

The Commission published a draft regulation in March proposing an A-to-G rating scale for datacenters, based on their energy and water efficiency. The system is intended to incentivize greater sustainability in their operations, especially as bit barn capacity is expected to expand greatly over the next decade, thanks to huge demand for AI and cloud services.

That earlier draft specified that facilities could offset greenhouse gas emissions by investing in clean energy certificates, but only if the projects concerned were in the same region as the data campus itself.

It is understood that this has been amended so that facilities operating in one country can offset their emissions by obtaining certificates from renewable projects in a different EU state. The proposed change was made at the behest of companies and lobby groups that argued it would increase their operating costs.

The EU’s efforts to press datacenters and other large energy users into adopting greater efficiency and sustainability measures have met with varying degrees of pushback.

Last year, the Climate Neutral Data Centre Pact (CNDCP) expressed concerns about standards for data campus efficiency the European Commission was considering, based on feedback from mandatory reporting introduced in the Energy Efficiency Directive (EED).

The group lists tech giants AWS, Microsoft, and Google among its signatories, as well as datacenter operators like Digital Realty, NorthC, and Vantage Data Centers.

Also last year, the Cloud Infrastructure Service Providers in Europe (CISPE) trade body was critical of the EU’s Water Resilience Strategy, warning that burdensome regulatory demands regarding water use might prompt operators to build outside Europe.

Another body, the European Data Centre Association (EUDCA), issued a statement this week affirming its “unwavering commitment” to climate-neutral datacenters and sustainable digital growth.

But it warned that Europe will not be able to “unlock the digital infrastructure capacity required for its AI and digital ambitions” without addressing structural challenges in the electricity system, including expansion of transmission and distribution grids, faster and more transparent permitting processes, and stable access to low-carbon electricity.

Meanwhile, Europe needs a policy framework that integrates water and energy efficiency if it wants to keep growing datacenter capacity to support its AI and cloud computing ambitions, according to a recent report.

The proposed environmental rating system is still listed as due for adoption in the third quarter of this year, but debate over the changes may push that back further. ®
