The author has also made a video about it recently: https://www.youtube.com/watch?v=euJgtLcWWyo It reminds me of Boldport, who made project kits that were also works of art [0]. The funky PCB traces and shapes were all hand

The article shows an example of a credit card field being a "number". Having made several online purchases, I realized I'm now frustrated by a CC number field that doesn't allow any spaces or dashes, or doesn't form

I think I was trying to get my entire music collection to fit onto my iPod, which at that time only had 10GB of space. And also, I love to optimize things, so it made no sense to me why squeezing 1-2 more words in the track title would infl

Just like the author, I too am quite particular about empty space in my MP3 files. When I was ripping my CD collection, I religiously tagged the MP3 files with ID3v1. Later on, I had some tracks whose titles were just a tad longer than 30 c

Thanks for posting this! It's an absolute godsend for creating small vector icons. As an example, I was looking at various popular sites for how they implement the "hamburger menu" icon, and it turns out that YouTube has a re

The processors on the Pis aren't really optimized for low power, and they aren't strictly ARM. These Broadcom chips have a VideoCore that starts up first, which then brings up the ARM cores (geerling goes into greater detail here

Seems like PodSwap have figured out how to replace the batteries without butchering them. (I’m not affiliated nor used them.) https://www.thepodswap.com/

This reminds me of Matthias Wandel, who also loves using the Raspberry Pi camera to monitor everything, including rodents [0], shooting squirrels [1], and keeping a heater aimed at him [2]. [0] https://www.youtube.com/watch?

I had the same idea! Except that I wanted to do it for Xenon 2 Megablast. It was a DOS game I grew up with and loved the intro music, so much that I wanted to play it outside the computer. You can run it in the browser here to listen to the

I believe that's a wakeup triggered using the RTC timer, which is still available in the C3.

From the datasheet, it looks like the C3 doesn't have the Ultra Low Power (ULP) co-processor. This co-processor was there on previous ESP32s and allowed you to run code for sensor monitoring or other basic tasks while the main CPU was

Disappointed that this teardown was more of a teaser without any PCB photos. Here are some YouTube videos that feature a better look at the PCB of the AirTag: [1] https://www.youtube.com/watch?v=63dJ5ytz37w [2] https:&#x2F

I too, found the anti-stalking features might hinder the use of AirTags for locating intentionally stolen items: (1) it has a removable battery, and also (2) "someone can tap [the tag] with their iPhone or NFC-capable device and instru

I was happy when I found out that my code was used in products by large companies like Disney and Hasselblad, but yet also ashamed because it was the cause of some of their product vulnerabilities and painted their product in a bad light: -

Interesting device! There's more details linked in the CNX Soft post [1], in particular, a thread on ODROID.com showing benchmarks [2]. The two disks are connected to the CPU via the ASM1061 SATA to PCIe x1 controller, meaning it can&#

To be honest, I think some form of abuse was bound to happen. Your files are encrypted client-side with JavaScript before uploading, so to the server it's just an opaque blob. Out of curiosity, I did some technical analysis¹ of how you

According to the blog post, TinyPilot also uses µStreamer (from this Pi-KVM project) to achieve its low latency. The initial revision of TInyPilot couldn't get low enough latency using the HDMI over IP extender otherwise. https:/

I was looking for a device to serve as my paper replacement in 2018 and came across the ReMarkable 1 tablet. Shortly after, Apple had announced a new iPad 9.7", now with Pencil support. This put both devices in the same price bracket.
