Tiny Code Reader: a $7 QR code sensor

news.ycombinator.com James Bowman 2025-07-24 08:22:51

Tiny Code Reader (TCR) caught my eye when it came out in 2023. It’s a very appealing idea: a self-contained seeing module that just decodes any QR code it sees. I immediately imagined applications in desktop manufacturing, a subject very dear to my heart. You can buy it from Adafruit, Sparkfun, and elsewhere. There’s a main page with a clear getting started guide, and a datasheet. Because it uses the Qwiic connector standard, setting it up is a breeze . It plugs directly into I²CDriver or I²CM

More Qi2.2 chargers are here, but here’s why you should wait before buying one

androidauthority.com Unknown 2025-08-02 16:00:43

Dhruv Bhutani / Android Authority TL;DR More products have been launched with Qi2.2 certification, promising wireless charging speeds at up to 25W with compatible devices. However, very few current smartphones officially support Qi2.2, but more are coming soon. More Qi2.2-certified accessories are also expected in the run-up to the iPhone 17 series launch, which will help widen product choice and stabilize prices for this bleeding-edge tech.

is a senior reporter who’s been covering and reviewing the latest gadgets and tech since 2006, but has loved all things electronic since he was a kid. Ugreen has announced what it claims is the “world’s first Qi2.2-certified power bank” that can wireless charge devices at speeds of up to 25W. Most wireless chargers in the US currently max out at just 15W of power delivery, but the Ugreen MagFlow Magnetic Power Bank will push that to 25W, matching the speed of the updated MagSafe charger Apple i

A New Kind of AI Model Lets Data Owners Take Control

wired.com Will Knight 2025-08-13 07:59:23

A new kind of large language model, developed by researchers at the Allen Institute for AI (Ai2), makes it possible to control how training data is used even after a model has been built. The new model, called FlexOlmo, could challenge the current industry paradigm of big artificial intelligence companies slurping up data from the web, books, and other sources—often with little regard for ownership—and then owning the resulting models entirely. Once data is baked into an AI model today, extract

Apple's MagSafe Charging Explained: Qi2, Faster Charging and Android Compatibility

cnet.com See Full Bio 2025-09-10 17:00:06

Apple's MagSafe for phones has evolved quite a bit since its debut on the 2020 iPhone 12 line, bringing magnetic wireless charging from the iPhone to the AirPods. Since Apple's MagSafe is compatible with the Qi2 wireless charging standard and has proven popular, we're starting to see Samsung, Google and OnePlus provide support for similar magnetic accessories. Even better, these wireless charging accessories are cheaper now than when MagSafe debuted, with companies such as Anker and Belkin maki

Modifying an HDMI dummy plug's EDID using a Raspberry Pi

news.ycombinator.com Doug Brown 2025-09-22 05:00:43

I recently found myself needing to change the monitor that a cheap HDMI “dummy plug” pretended to be. It was a random one I had bought on Amazon several years ago that acted as a 4K monitor, and I needed it to be something simpler that didn’t support a 4K resolution. The story behind why is a long one that I’m still figuring out and might eventually become a separate blog post in the future. If you’re not familiar with dummy plugs, here’s a quick primer: they are tiny dongles you can plug into

Google Pixel 10 may fail to live up to our MagSafe dreams, after all

androidauthority.com Unknown 2025-09-25 16:28:50

Rita El Khoury / Android Authority TL;DR Google is preparing a range of “Pixelsnap” accessories for the Pixel 10 that support wireless charging. Despite Qi2 support, the phone may require the use of a case to add the magnets needed for alignment. In addition to Google’s own accessories, look for a range of similar Made by Google solutions from third parties. What is so hard about giving Android users what they want? When it comes to wirelessly charging our phones, we’re not asking for that m

It’s been 84 years, but my dream of ‘MagSafe’ on a Pixel is almost here

androidauthority.com Unknown 2025-09-26 17:00:32

Dhruv Bhutani / Android Authority I am an Android and a Pixel fan who has been heralding MagSafe as the coolest and most useful smartphone accessory improvement since sliced bread — or USB-C to stay within the metaphor. So when Qi2 was announced with a hint of MagSafe backwards compatibility, I was in nerd heaven. Finally — finally! — I’d be able to dip into a large ecosystem of accessories and use them on my Pixel phones. But Qi2’s announcement came and went, and the weeks, months, and years

Pixelsnap, Google's belated answer to MagSafe, could arrive alongside the Pixel 10

engadget.com Unknown 2025-09-26 15:45:27

Android phones that support Qi2 wireless chargers that are magnetically secured in place might finally be hitting the market. Android Authority reports that Google plans to add Qi2 charging with the upcoming Google Pixel 10. The Qi2 standard was announced at CES in 2023, and was developed with substantial contributions from Apple. The new design iterated on the Qi standard by adding magnets that would help ensure a perfect alignment, among other improvements. That magnetic alignment tech was bui

This $25 wireless charger is better than Apple's product (and comes with a long cord)

zdnet.com Adrian Kingsley-Hughes 2025-06-11 14:00:18

ZDNET's key takeaways The Anker MagGo Qi2 magnetic wireless charger pad is available for only $25. It's a cheap high-speed Qi2 compatible wireless charger, but well-built and features a long cord. There is no charger included with the standard option (this kit costs an additional $9). $24.99 at Amazon Recently, I've seen more and more power banks integrating wireless charging capabilities, such as the Anker MagGo Qi2. These devices are appealing for their ability to attach directly to the bac
