Ever since I got AMD, Intel, and Nvidia graphics cards to run on a Raspberry Pi, I had a nagging question: What's the point? The Raspberry Pi only has 1 lane of PCIe Gen 3 bandwidth available for a connection to an eGPU. That's not much. Especially considering a modern desktop has at least one slot with 16 lanes of…
Narrowband trichromatic (RGB) light sources are superior to broadband (white) light for scanning color negative film; there are very good reasons why all commercial film scanners use RGB. ( film scanners were using blue LEDs at least a decade before they would be widely used in consumer products! ) Scanning film with…

In an important step toward a fully implantable intracortical brain-computer interface system, BrainGate researchers demonstrated the first human use of a wireless transmitter capable of delivering high-bandwidth neural signals.
Using Python 3.6, OpenCV, Dlib and the face_recognition module
Oscar's thoughts too large for a tweet
The best platform for cycle-accurate retro PC emulation may just be the Mac. The M6 achieved a stable 600MHz clock using a 6.0 derived 86Box build.
Looking back at this week's posts on the design, specifications, and performance of Cloudflare’s Gen X servers using AMD CPUs. Every server can run every service. This architectural decision has helped us achieve higher efficiency across the Cloudflare network.
A closer look at a fashion trend in printed circuit board design.
A fun side project for a great cause featuring Core Motion, SwiftUI, a little help from AI, and a pair of AirPods to count 100 push-ups a day.
See how an old car is turned into a powerful generator, a DIY project that reuses a vehicle to produce electricity.
Introduction I have been taking pictures and making short video clips to demonstrate different aspects of the displays and optics of the Meta Quest Pro (MQP) for over a month. It was a bit of an on…
A plain-language guide to AB2047 you can share with your school board, PTA, or neighbor. Learn what's at stake and how to take action.

The 80386 is the most important CPU Intel ever produced. It confirmed the importance of the x86 line and sparked a computing revolution. And yet it almost never saw the light of day. This is the history of the 386 and why it was such a landmark.
Apple's product design teams should do a better job eliminating unwanted radio frequency emissions from their product!
It turns out, you can attach an external GPU to a Raspberry Pi 5. So my natural first question is, can I game on it? Let’s try it out and compare it with some similar computers. Just a quick FTC required note: When you buy through my links, I may earn a commission. For the showdown of crappy gaming computers, we’ll…
Discreetly modding my friend’s apartment intercom to work with Apple Home.
If you’re connecting to your rPi via SSH, you’d have to update your DISPLAY environment variables by issuing
This post is a high-level explainer for my Master’s thesis, which involves designing hardware architectures for ultrafast inference and online learning using the Kolmogorov-Arnold Network (KAN) architecture. I’ll assume familiarity with standard machine learning concepts, as well as some understanding of hardware and…
Thanks for the featured writeup Hackaday! Make sure to check out the comments over there as well. Looks like Hackernoon picked it up as well, make sure to check in with the comments there too. It would be great if you could also head over to Hacker News, give an upvote, and join in the comments there. Let's get this…
The FreeSRP is an affordable software-defined radio (SDR) I decided to design because there were no existing options that filled the gap between the $300 and relatively narrow bandwidth and low resolution HackRF and the better performing USRP s you can get for about $700. Of course it will be fully open source, but…
The Intel N100-based Radxa x4 has taken the headlines over the last week or so, and for good reason! Does the x86 SBC live up to the hype?
Collaboration aims to advance new technologies that expand infrastructure choice while preserving mission-critical environments ARMONK, N.Y., April 2, 2026 /PRNewswire/ -- IBM (NYSE: IBM) today...
Collection of odds and ends relating to e-readers including personal reminisces Background # Reading has been a huge part of my life. The written word has had arguably more of an impact on my life than anything I have experienced in person. As a kid back in early 2000’s; this meant a lot of library trips and saving…
When putting the Raspberry Pi Zero vs a MangoPi MQ Pro, who wins? Can the RISC-V D1 chip hold its own?
Whether controlled by an artificial intelligence or a remote human operator, armed police robots and drones pose an unacceptable threat to civilians. The ongoing revolution in the field of robotics requires us to act now to prevent a new era of police violence.
And a surviving example of one surfaced in December 2024.
