Undocumented 8086 instructions, explained by the microcode
What happens if you give the Intel 8086 processor an instruction that doesn't exist? A modern microprocessor (80186 and later) will gener...

The Super Game Boy allows you to play Game Boy games on your Super Nintendo. This is an impressive feat, when you consider that the two consoles share basica...
I work in a company that uses custom electronic boards, so there are plenty of instruments floating around that electrical engineers employ to debug faulty connections and solderings. One kind of tools used are the oscilloscopes, tools that measure signals and plot them in a graphically understandable way. We have a…
Personal preference is an interesting thing. People can have a particular preference for something until they are able to experience something else. As we gain experience, our personal preference gets more finely tuned.
Concise summary of the Hilbert transform: mathematics, effects on signals, and applications in telecommunications.
The Intel 8086 microprocessor (1978) started the x86 architecture that continues to this day. In this blog post, I'm focusing on a small p...
A breadboard with visual indication of overheating of the parts.
The ARM powered Thinkpad x13s is the first truly premium Windows on ARM laptop. Let's see how that actually stacks up as a software engineer!
For the last 10 years, I have been interested in hi-DPI monitors, and recently I read about an interesting new monitor: Dell’s 32-inch 6K monitor (U3224KBA), a productivity monitor that offers plenty of modern connectivity options like DisplayPort 2, HDMI 2 and Thunderbolt 4.
With all that Dec Alpha talk , and how hard it is to get hardware, and how seemingly exclusionary it is, I thought I would try to touch on a more available 64bit ‘risc’ platform, for the masses!
The Intel i960 was a remarkable 32-bit processor of the 1990s with a confusing set of versions. Although it is now mostly forgotten (outs...

My trusty old smartwatch recently stopped working. It was a Garmin Vivomove HR, a minimal hybrid watch with regular watch hands and a tiny hidden screen that showed notifications and messages. It served me well for quite some time but unfortunately the hidden screen has stopped working and it would cost me as much to…
The instructions below set up Time Machine using the Apple File Protocol (AFP). After publishing this blog post, I’ve been told that this is now deprecated and that Samba should be used instead. I’ll update this blog post in the near future.
Background Back in April, the hardware news site cnx-software featured a very nice new small Linux board called Breadbee , that was design...
Introduction Part 1 and Part 2 of this series on the Apple Vision Pro (AVP) primarily covered the hardware. Over the next several articles, I plan to discuss the applications Apple (and others) sug…
This post is about building an FPGA based networked key-value-store in the functional hardware description language Clash. I’ll describe my FPGA-tailored hashtable design, the testing framework I built for it, and its performance and resource usage.
A dive into what x86 instruction are decoded into various processors, to determine the truth of the idea that they're just RISC-like internally.
Introduction This part will primarily cover the hardware and related human physical and visual issues with the Apple Vision Pro (AVP). In Part 3, I intend to discuss my issues with the applications…

Exploiting a Video Camera's Rolling Shutter to Recover Secret Keys from Devices Using Video Footage of Their Power LED
I guess this is a review of sorts, so here's the review part: you should buy Tech by Androda's new 7MB Macintosh Portable RAM card . On my D...
After a long time of not publishing anything and being passive about doing any writing in this blog, I am coming back for … however many articles I can. Today I want to talk about an underrat…
Apple Vision is incredibly compelling, first as a product, and second as far as potential use cases. What it says about society, though, is a bit more pessimistic.
Hello and welcome back to The Cool Blog. I've been meaning to write more but I had these things called finals and then I had to move home for the summer and then I got addicted to Satisfactory again and yeah. Anyway I'm back and time for me to share a project of mine that I've been working on since like March.
My daughter found my Psion 3a the other day, tucked at the back of a cupboard she was clearing out for me. It looked fine and is still in excellent aesthetic condition, and fortunately I had left n…
After buying a new Philips Sonicare toothbrush I was surprised to see that it reacts to the insertion of a brush head by blinking an LED. A quick online search reveals that the head communicates with the toothbrush handle to remind you when it’s time to buy a new one. From the Philips product page: seems to be REALLY…
