Lately, I’ve been really into 3D printing along with asking myself what we can do with this technology now that it’s become, well, a technology. (At least, in the “this is a thing that can now be used, is robust, and is generally accessible to many people” sense of technology.) The first thing to print on a 3D printer…
Modern processors have the ability to execute many instructions per cycle, on a single core. To be able to execute many instructions per cycle in practice, processors predict branches. I have made the point over the years that modern CPUs have an incredible ability to predict branches. It makes benchmarking difficult…
I have recently been working on tuning circuits, which typically consist of an inductor and a capacitor (i.e. an LC circuit). For those not familiar with inductors, they are passive components that store energy in a magnetic field. They oppose changes in current, meaning that they pass direct current (DC) and block…
round 2: rooting & analysing firmware of the TP-Link TL-WR841N
Spacelab was a reusable laboratory that could be carried in the cargo bay of the Space Shuttle, providing lab space for astronauts and exper...
Emulating the unknown: Controlling Sewing Machines with a Game Boy
The Nintendo Entertainment System. Is it the platonic ideal of an 8-bit video game system? Well, only because it’s so prominent and successful– it’s actually...
A celebration into the IBM PC, the Model F/XT keyboard, where it came from and what it became
We owe computers not to Charles Babbage, but to the invention of electronically-controlled working memory.
A story of sharp edges, segfaults, and standards
Intel ushers in the next generation of AI PCs with exceptional performance, graphics and battery life; available this month
Earlier this year we published a puzzle that handed you a complete neural network and asked you to figure out what it did. The response was great, so we’ve made another one! This time, we’re going much deeper down the tech stack.
After learning Apple killed off FireWire (IEEE 1394) support in macOS 26 Tahoe, I started looking at alternatives for old FireWire equipment like hard drives, DV cameras, and A/V gear. I own an old Canon GL1 camera, with a 'DV' port. I could plug that into an old Mac (like the dual G4 MDD above) with FireWire—or even…

The FPGA 386 core I've been building now boots DOS, runs applications like Norton Commander, and plays games like Doom. On DE10-Nano it currently runs at 75 MHz. With the core now far enough along to run real software, this seems like a good point to step back and look at one of the 80386's performance-critical…

Capacitor vendors don't want you to know this! Save money on capacitors by spending more on other components
Pushing affordable marine conservation forward with autonomous marine robots powered by Raspberry Pi Compute Module 4.
About a eight weeks ago I had virtually no interest in calculators. Blank, dull, tedious-looking objects that remind me of long, arduous rainy afternoons in 1980’s/1990’s school maths classes.
In the 1980s, if you wanted your computer to do floating-point calculations faster, you could buy the Intel 8087 floating-point coprocessor ...
This is a PCMCIA development board for retro-computing enthusiasts who want to experiment with audio, networking, and expansion on vintage laptops and mobile devices. While ISA users have enjoyed projects like PicoGUS and PicoMEM, PCMCIA users have long been limited to scarce legacy cards with narrow functionality …

There are lots of things that affect the quality of photographs. The biggest one is the skill of the photographer behind the camera.
My complete guide for setting up the ASRock BC-250. You can’t beat its price for performance, and it’s perfect for those who love tinkering with projects.
In keeping with my passion (?) for displaying local news articles in unexpected places , I figured it would be a fun project to try and see what it would take to display current local news on the Nintendo Wii console’s News Channel .
How to emulate an Atari YM2149 audio chip on Amiga at litteraly 0 CPU cost, by Arnaud Carré
The team is the first to directly observe a unique property in an altermagnetic candidate material, key evidence of a new phase of magnetism.
