It’s one thing to learn about transmission lines in theory, and quite another to watch a voltage pulse bounce off an open connector. [Alpha Phoenix] bridges the gap between knowledge and understanding in the excellent videos after the break. With a simple circuit, he uses an oscilloscope to visualize the propagation of electricity, showing us exactly how signals travel, reflect, and interfere.
The experiment relies on a twisted-pair Y-harness, where one leg is left open and the other is terminated by a resistor. By stitching together oscilloscope traces captured at regular intervals along the wire, [Alpha Phoenix] constructs a visualization of the voltage pulse propagating. To make this intuitive, [Alpha...

Les gardiens de la révolution iraniens ont conseillé « aux employés, professeurs et étudiants des universités américaines de la région de s’éloigner d’un kilomètre » des campus pouvant être visés.

[Tommy] at Oskitone has been making hardware synth kits for years, and his designs are always worth checking out. His newest offering Space Dice is an educational kit that is a combination vintage sci-fi space laser sound generator, and six-sided die roller. What’s more, as a kit it represents an effort to be genuinely educational, rather than just using it as a meaningless marketing term.
There are several elements we find pretty interesting in Space Dice. One is the fact that, like most of [Tommy]’s designs, there isn’t a microcontroller in sight. Synthesizers based mostly on CMOS logic chips have been a mainstay of DIY electronics for years, as have “electronic dice” circuits. This device mashes...

The common narrative around device design is that you can have repairability or a low price, but that they are inversely proportional to each other. Apple’s new budget MacBook Neo seems to attempt a bit of both.
Brittle snap-fit enclosures or glue can make a device pop together quickly during manufacture, but are a headache when it comes time to repair or hack it. Our friends at iFixit tore down the Neo and found it to be the most repairable MacBook since the 2012 unibody model. A screwed in battery, and modules for many of the individual components including the USB ports and headphone jack make it fairly simple to replace individual components. Most of those components are even accessible as soon as you...

Slop yourself. | Image: Suno Suno just released one of its biggest updates yet with v5.5 of its AI music model. Where previous updates focused mostly on improving fidelity and creating more natural vocals, v5.5 is about giving users more control. It includes three new features: Voices, My Taste, and Custom Models.
In the release notes, Suno says that Voices is its most requested feature. It lets users train the vocal model on their own voice. They can upload clean accapellas, finished tracks with backing music, or just sing directly into the mic on their phone or laptop. The cleaner and higher quality the recording, the less data is required. And to prevent someone fro …

Like many high-tech companies Tesla runs a bug bounty program. But in the case of a car manufacturer, this means that you either already have one of their cars, are interested in buying one, or can gain access to its software-bits in another legal manner. Being a Tesla-less individual, yet with an interest in hunting bugs [David Schütz] thus decided to pursue the option of obtaining the required parts from crashed Tesla cars. Specifically [David] was interested in the Tesla Model 3 and its combined Media Control Unit (MCU) and Autopilot computer (AAP) assembly. In addition to the main unit, it also requires – obviously – a power supply, and the proprietary display. These were all obtained fairly easily,...

Amazon loves to manufacture an event. March is historically a dry spell for deals; however, with Amazon’s third annual Big Spring Sale, which runs through March 31st, the retail behemoth is hoping to lure in would-be shoppers with the promise of steep(ish) savings and discounts on more seasonal, spring-centric items to hold folks over until Prime Day surfaces at the onset of summer. The bulk of the deals we’re seeing right now aren’t quite on par with Black Friday or Prime Day, and, as with most shopping events, not everything on sale is worth picking up. That said, Amazon’s latest sale is one of the first big opportunities we’ve seen this year to save — and bypass some tariff-induced pain —...

The SteelSeries Arctis Nova Pro Wireless came out almost four years ago, yet it’s still one of the best gaming headsets you can buy. Turns out, it’s not easy for other companies to duplicate all that SteelSeries got right with this one — mixing multiple audio sources, active noise cancellation, a retractable mic, hot-swappable batteries, and more. Normally priced at $379.99, it’s down to $299.99 at Amazon during the company’s Big Spring Sale that lasts through April 1st at 2:59AM ET.

Hackers can be a strange folk. Our idea of beauty, for instance, can be rather odd. This week, Hackaday saw a few projects that were not just functional – the aesthetics were the goal. I don’t think we’ll be taking over the fine art world any time soon, but I’m absolutely convinced that the same muse that guides the hand that holds the paintbrush sometimes also guides the hand holding the soldering iron.
Take “circuit sculpture”, for instance. Heck, we even give it an art-inspired name that classifies it correctly. This week’s project that got me thinking about the aesthetics of hand-bent wire circuits was this marvelous clock build, but the works of Mohit Bhoite or Kelly Heaton are also absolute...

Samsung, like many companies using generative AI in their advertising, hasn’t placed an AI label on several videos shared through its TikTok accounts, and the fine print doesn’t always contain the answers. | Image by Samsung I've been struggling to tell whether the ads appearing in my TikTok feeds have been made with generative AI tools. As someone who spends a great deal of time scrutinizing images and videos for the usual "tells" that something was synthetically generated, some of the promotions I've seen have definitely sparked suspicion. For several weeks, I didn't see any examples with the AI disclosure required by TikTok's advertising policies, however, so I had no way of knowing for sure.

Is social media not just bad, but illegally bad? Should tech companies pay for making it that way? According to two US juries - and no shortage of outside commentary - the answer to both questions is "yes."
Earlier this week, two juries - one in New Mexico, one in Los Angeles - held Meta liable for a total of hundreds of millions of dollars for harming minors. YouTube was also found liable in Los Angeles, and both companies are appealing their losses. In one sense, the decisions were surprising. Meta and Google operate platforms for transmitting speech and are typically protected in a variety of ways by Section 230 and the First Amendment; …

Son intelligibilité ne réside ni dans les seules capacités internes d’Israël, des États-Unis, de l’Iran et des pays du Golfe, ni dans le seul volume des échanges hostiles entre eux, mais dans la structure des interfaces qui les couplent. La variable décisive n’est pas la quantité brute de flux stratégiques, mais la qualité organisationnelle du régime conjoint qu’ils produisent. Les pays du Golfe y occupent une place non secondaire mais architecturale : ils constituent une charnière de couplage où se concentrent les...

“In response to anthropogenic forcing, the Earth’s surface generally warms as greenhouse gases trap outgoing longwave radiation. Counterintuitively, however, some regions exhibit surface cooling against this global warming background—a phenomenon known as a warming hole. Beyond the well-documented warming holes over the North Atlantic and southeastern United States, here we show that increasing atmospheric CO2 concentrations can also induce summertime cooling over India. Due to the direct radiative effect of CO2, warming of the Eurasian continent relative to surrounding oceans, low-level moisture transport and vertical motion are enhanced over India. Combined with abundant summer-monsoon moisture and the...

“Forest growth exceeded harvesting levels in 23 EU countries with available data in 2023. A simple way to gauge whether wood production is sustainable is to compare the amount of wood harvested or otherwise removed in a year with the forest’s natural growth, known as the net annual increment, Eurostat reported on Friday. In 2023, the largest surplus of growth over removals was recorded in Romania at 39.9 million cubic metres, followed by Sweden at 26.4 million and Poland at 26.3 million. Estonia was the only country where removals were higher than growth, with 11.6 million cubic metres removed compared with a net annual increment of 9.1 million.” From The Brussels Times.
