The Curse of Soldered RAM
The trend for soldered on RAM in modern laptops is truely evil especially in these current trying times of shortage induced high prices. I normally run 2 laptops, one for personal stuff and one for…

The likely cheapest home-made Michelson interferometer
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…

How many branches can your CPU predict?
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…

Making Ferrite Core Inductors at Home
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…

Can you reverse engineer an ASIC?
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.

Using FireWire on a Raspberry Pi
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…

80386 Memory Pipeline
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…

A True Telnet BBS on a Casio Calculator
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.
