Run a legal LTE network at home for $100
Yes, you read that right. Without the need for Faraday cages or signal-blocking measures, you can build a legal LTE network at home (in the US) for around $100, capable of transmitting continuously 24/7.

Defragging my old Dell's UEFI NVRAM
I’m setting up an old Dell box (2011-era tech). I was migrating to some new boot drives and setting up grub on them again. Got to the point of deleting the old boot entries and adding new ones, and got an error like Could not prepare boot variable: No space left on device. Weird, because there weren’t that many EFI…

Reverse Engineering Yaesu FT-70D Firmware Encryption
This article dives into my full methodology for reverse engineering the tool mentioned in this article. It's a bit longer but is intended to be accessible to folks who aren't necessarily advanced reverse-engineers.

Whatever happened to cheap eReaders?
Way back in 2012, The Guardian reviewed an eInk reader which cost a mere £8. The txtr beagle was designed to be a stripped-down and simplified eReader. As far as I can tell, it never shipped. There were a few review units sent out but I can't find any evidence of consumers getting their hands on one. Also, that £8…

I made a small LED panel
I bought a really small 8x8 LED panel a while ago because I have a problem. I just can’t resist a nice WS2812 LED panel, much like I can’t resist an e-ink display. These days I manage to stay sober, but once in a while I’ll see a nice cheap LED panel and fall off the wagon. It has now been thirteen minutes that I have…

Fundamental flaws of SIMD ISAs (2021)
According to Flynn’s taxonomy SIMD refers to a computer architecture that can process multiple data streams with a single instruction (i.e. “Single Instruction stream, Multiple Data streams”). There are different taxonomies, and within those several different sub-categories and architectures that classify as “SIMD”.

The Lost Japanese ROM of the Macintosh Plus
If you look for information about the Macintosh Plus and its ROM, you’ll usually find that the ROM has a capacity of 128 KB and that it exists in three revisions . But that’s incorrect: there’s a fourth ROM, 256 KB in size, which includes fonts for kanji (Japanese characters). And I found (and preserved) this ROM. I’m…

8086 Microcode Browser
Since releasing 486Tang , I’ve been working on recreating the 8086 with a design that stays as faithful as possible to the original chip. That exploration naturally led me deep into the original 8086 microcode — extracted and disassembled by Andrew Jenner in 2020.

Rust on the RP2350 (2024)
Today sees the announcement of the latest additions to Raspberry Pi's microcontroller line-up - the RP2350 family. I've had prototype units for a while, and you can run Rust code on it today. To my knowledge this is the first ever microcontroller launch with Rust support out-of-the-box.
