L'articolo proviene da #StartMag e viene ricondiviso sulla comunità Lemmy @Informatica (Italy e non Italy 😁)
Un ex dipendente di Tokyo Electron è sospettato di aver sottratto segreti industriali a Tsmc, la più importante azienda manifatturiera di microchip al mondo. Il caso ci ricorda che la proprietà intellettuale è centrale nella competizione



Whispers From The Void, Transcribed With AI


Screenshot of audio noise graph

‘Hearing voices’ doesn’t have to be worrisome, for instance when software-defined radio (SDR) happens to be your hobby. It can take quite some of your time and attention to pull voices from the ether and decode them. Therefore, [theckid] came up with a nifty solution: RadioTranscriptor. It’s a homebrew Python script that captures SDR audio and transcribes it using OpenAI’s Whisper model, running on your GPU if available. It’s lean and geeky, and helps you hear ‘the voice in the noise’ without actively listening to it yourself.

This tool goes beyond the basic listening and recording. RadioTranscriptor combines SDR, voice activity detection (VAD), and deep learning. It resamples 48kHz audio to 16kHz in real time. It keeps a rolling buffer, and only transcribes actual voice detected from the air. It continuously writes to a daily log, so you can comb through yesterday’s signal hauntings while new findings are being logged. It offers GPU support with CUDA, with fallback to CPU.

It sure has its quirks, too: ghost logs, duplicate words – but it’s dead useful and hackable to your liking. Want to change the model, tweak the threshold, add speaker detection: the code is here to fork and extend. And why not go the extra mile, and turn it into art?

Tearing Down A Mysteriously Cheap $5 Fiber Optic To Cable TV Adapter


In his regular browsing on AliExpress, [Ben Jeffrey] came across something he didn’t understand—a $5 fiber optic to RF cable TV adapter. It was excessively cheap, and even more mysteriously, this thing didn’t even need power. He had to know how it worked, so he bought one and got down to tinkering with it.
Inside the device in question.
[Ben] needed some hardware to test the device with, so he spent $77 on a RF-to-fiber converter and a cheap composite-to-RF modulator so he could test the $5 fiber-to-RF part. A grand expenditure to explore a $5 device, but a necessary sacrifice for the investigation. Once [Ben] hooked up a fiber optic signal to the converter, he was amazed to see it doing its job properly. It was converting the incoming video stream to RF, and it could readily be tuned in on a TV, where the video appeared clean and true.

It was disassembly that showed how simple these devices really are. Because they’re one-way converters, they simply need to convert a changing light signal into an RF signal. Inside the adapter is a photodiode which picks up the incoming light, and with the aid of a few passives, the current it generates from that light becomes the RF signal fed into the TV. There’s no need for a separate power source—the photodiode effectively works like a solar panel, getting the power from the incoming light itself. The part is ultimately cheap for one reason—there just isn’t that much to it!

It’s a neat look at something you might suspect is complex, but is actually very simple. We’ve explored other weird TV tech before, too, like the way Rediffusion used telephone lines to deliver video content. Video after the break.

Clock of Clocks Expands, Goes Digital


Some people just want to have their cake and eat it too, but very few of us ever get to pull it off. [Erich Styger] has, though with V5 of his “MetaMetaClock”— a clock made of clocks, that uses the orientation of the hands to create digits.

We’ve seen previous versions of this clock. As before, the build is exquisitely detailed and all relevant files are on GitHub. This version keeps the acrylic light-pipe hands of version 4, but adds more of them: 60 clocks vs 24. Larger PCBs are used, grouping the dual-shaft steppers into groups of four, instead of the individual PCBs used before. Each PCB has an NXP LPC845 (a Cortex M0 microcontroller) that communicates on an RS-485 bus. Placing four steppers per microcontroller reduces parts count somewhat compared to previous versions (which had each ‘clock’ on its own modular PCB) albeit at the cost of some flexibility.

While the last version used veneers on its face, this version is cut by CNC by from a large slab of oak. It’s certainly the most attractive version yet, and while bigger isn’t always better, more clock faces means more potential effects. Date? Time? Block letters? Arbitrary text? Kaleidoscopic colours from the RGB LEDs? It’s all there, and since it’s open source, anyone who builds one can add more options. A BLE interface makes it quick and easy to wirelessly switch between them or set the time.

It’s nice sometimes to watch projects like this improve incrementally over time. [Erich] mentions that he plans to add Wifi and a web-based user interface for the next version. We look forward to it, and are grateful to [jicasi] for the tip. Just as it is always clock time at Hackaday, so you can always toss a tip of your own into the box.

Eventually [Erich] will have enough clocks for Bad Apple, but this version can do short text strings among many other effects. Check his blog for more demo videos.

2025 One Hertz Challenge: The Real-Time Clock The VIC-20 Never Had


Like many early microcomputers, the Commodore VIC-20 did not come with an interna real-time clock built into the system. [David Hunter] has seen fit to rectify that with an add-on module as his entry to the 2025 One Hertz Challenge.

[David]’s project was inspired by a product that Hayes produced in the 1980s, which provided a serial-port based real-time clock solution for computers that lacked one on board. The heart of the project is an Arduino Uno, which itself uses a Dallas DS3231 RTC module to keep accurate time. [David] then drew from an IEC driver developed by [Lars Pontoppidan] for the MM2IEC project. This enables the Arduino to report the time to the VIC-20 via its IEC port.

The project is a neat way to provide a real-time clock source to programs written in Commodore BASIC. It’s also perfectly compatible with the IEC bus, so it can be daisy chained along with printers and disk drives without issue. [David] hasn’t tested it with a Commodore 64, but he suspects it should work just as well on that platform, too.

If you’ve ever wanted to build something clock-based for the VIC-20 but didn’t know how, this is a great piece of hardware to solve that problem. Meanwhile, you might find joy in reading about real-time clock hacks for other systems like the Raspberry Pi. Meanwhile, if you’re working on your own nifty timekeeping projects, don’t hesitate to let us know!

Qualcuno può dare una mano?


tastiera virtuale per ipovedenti


ora avrei bisogno di aiuto..

Mio fratellino (storia lunghissima che racconterò, forse, un'altra volta) è ipovedente.
Purtroppo essendo nato sordo, non parla nemmeno. Grazie agli impianti cocleari sente e capisce quasi tutto, ma non emette suoni.
Grazie alla tecnologia, però, sta imparando a comunicare. Sa leggere e scrivere al computer, anche se solo su nostro input, mai in modo spontaneo.
Usa una tastiera fisica per ipovedenti, con tasti grandi e ad alto contrasto, e la gestisce discretamente bene.
Recentemente ci siamo dotati di una lavagna interattiva per supportare il suo percorso educativo e di sviluppo.
Ho collegato la tastiera alla lavagna, ma non vuole usarla: preferisce stare in piedi e utilizzare quella virtuale direttamente sullo schermo della smart board (o forse semplicemente associa la tastiera fisica al computer... poco importa!).

Problema: la tastiera virtuale dobbiamo ri-attivarla spesso, inserire il CAPS LOCK (sa leggere e scrivere solo in maiuscolo) e con certe app non funziona..
Ecco perché avrei bisogno di una tastiera virtuale — che rimanga sempre visibile, o almeno di facile attivazione, sullo schermo della smart board — ad alto contrasto e con lettere maiuscole. La lavagna è basata su android.

Grazie se qualcuno può aiutarmi

Behind the Blog: Speculation, Distraction, and Smart Glasses


This is Behind the Blog, where we share our behind-the-scenes thoughts about how a few of our top stories of the week came together. This week, we discuss Wikipedia's ethos and zooming in on a lot of pictures of cops' glasses.

EMANUEL: I’m going to keep it very short this week because I’m crunching on a feature, but I wanted to quickly discuss Wikipedia.

This week I wrote a story about a pretty in-the-weeds policy change Wikipedia’s community of volunteer editors adopted which will allow them to more quickly and easily delete articles that are obviously AI generated. One thought I’ve had in mind that didn’t make it into the last few stories I’ve written about Wikipedia, and one that several people shared on social media in response to this one, is that it’s funny how many of us remember teachers in school telling us that Wikipedia was not a good source of information.

Hackaday Podcast Episode 332: 5 Axes are Better than 3, Hacking Your Behavior, and the Man Who Made Models


Elliot and Dan got together this week for a review of the week’s hacking literature, and there was plenty to discuss. We addressed several burning questions, such as why digital microscopes are so terrible, why computer systems seem to have so much trouble with names, and if a thermal receipt printer can cure ADHD.

We looked at a really slick 5-axis printer that COVID created, a temperature-controlled fermentation setup, and a pseudo-Mellotron powered by a very odd tape recorder. We also learned little about designing 3D printed parts with tight tolerances, stepping a PC power supply up to ludicrous level, and explored a trio of unique entries for the One Hertz Challenge.

And for the Can’t Miss section, we looked at what happens to planes when they get hit by lightning (and how they avoid it), and say goodbye to the man who launched a lot of careers by making model kits.

It was also exciting to learn that the first day of Supercon is Halloween, which means a Friday night sci-fi cosplay party. It’s gonna be lit.

Più o meno una volta al mese, torno a scrivere qualcosa 😁
Le cose stanno iniziando ad andare meglio (non lavorativamente), anche se il mio tempo libero è sempre pochissimo.
Comunque domenica mattina partiamo in vacanza e non vedo l'ora. Abbiamo proprio bisogno di ricaricarci un po'. Andremo in Slovenia 😀

Io, molto a rilento, sto cercando di togliere google e tanto altro schifo dalla mia vita. E questo mi fa sentire bene.

Congress Launches Investigation into Flock After 404 Media Reporting


Two members of Congress have launched a formal investigation into automatic license plate reader (ALPR) company Flock and demanded it turn over details of all searches of its national camera network concerning Immigration and Customs Enforcement (ICE), Customs and Border Protection (CBP), and abortions. The move comes after 404 Media revealed that local cops were performing lookups in Flock on behalf of ICE or for immigration enforcement, and that a Texas officer searched cameras nationwide looking for a woman who self-administered an abortion.

The congressional investigation is just the latest impact from those articles, which have resulted in a wave of similar coverage around the country and Flock making major changes to its platform. The letter announcing the investigation explicitly cites 404 Media’s articles.

It Looks Like a School Vape Detector. A Teen Hacker Showed It Could Become an Audio Bug


This article was produced with support from WIRED.

A couple of years ago, a curious, then-16-year-old hacker named Reynaldo Vasquez-Garcia was on his laptop at his Portland-area high school, seeing what computer systems he could connect to via the Wifi—“using the school network as a lab,” as he puts it—when he spotted a handful of mysterious devices with the identifier “IPVideo Corporation.”

After a closer look and some googling, Garcia figured out that a company by that name was a subsidiary of Motorola, and the devices he’d found in his school seemed to be something called the Halo 3C, a “smart” smoke and vape detection gadget. “They look just like smoke detectors, but they have a whole bunch of features like sensors and stuff,” Garcia says.

As he read more, he was intrigued to learn that the Halo 3C goes beyond detecting smoke and vaping—including a distinct feature for discerning THC vaping in particular. It also has a microphone for listening out for “aggression,” gunshots, and keywords such as someone calling for help, a feature that to Vasquez-Garcia immediately raised concerns of more intrusive surveillance.
