Two Weeks Until Tapeout
Chronicles of a bad idea. Or how I designed a systolic array with in-silicon debug infrastructure from scratch in under two weeks, and taped it out on Global Foundry 180 nm though a Tiny Tapeout experimental shuttle.

80386 Multiplication and Division
When Intel released the 80386 in October 1985, it marked a watershed moment for personal computing. The 386 was the first 32-bit x86 processor, increasing the register width from 16 to 32 bits and vastly expanding the address space compared to its predecessors. This wasn't just an incremental upgrade—it was the…

Notes on Apple's Nano Texture (2025)
2024 Nano Texture Macbook Pro on the left; 2021 Glossy Macbook Pro on the right TLDR: the Nano Texture performs wonderfully anywhere where light used to be a factor and used to force me to shade my screen or avoid the place entirely. I’m less concerned with where I sit indoors. Coffee shops / offices with skylights or…

A Year of 3D Printing
If you'd asked me a few years back if I thought I'd buy a 3D printer, I would have said no. My experience of 3D printers back when I was in college was that they were very slow, expensive, frequently failed mid-print, and needed constant calibration...

Raspberry Pi's New AI Hat Adds 8GB of RAM for Local LLMs
Today Raspberry Pi launched their new $130 AI HAT+ 2 which includes a Hailo 10H and 8 GB of LPDDR4X RAM. With that, the Hailo 10H is capable of running LLMs entirely standalone, freeing the Pi's CPU and system RAM for other tasks. The chip runs at a maximum of 3W, with 40 TOPS of INT8 NPU inference performance in…

Floppy disks turn out to be the greatest TV remote for kids
Modern TVs are very poorly suited for kids. They require using complicated remotes or mobile phones, and navigating apps that continually try to lure you into watching something else than you intended to. The usual scenario ends up with the kid feeling disempowered and asking an adult to put something on. That…

The Z80 Membership Card (2015)
The microcomputer is an incredible, revolutionary invention. Like the electric light, the printing press, and the wheel, it has changed the world. Without microcomputers, the internet, and perhaps even "life as we know it" would not be possible!

RTX 5090 and Raspberry Pi: Can it game?
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…

CPU Counters on Apple Silicon: article + tool
Last time I wrote about profiling in Zig on Apple Silicon, I touched on PMU counter profiling. This time I decided to go further and create my own tool to fetch all available counters for Apple Silicon processors (M1, M2, and later). Brief explanation of PMU counters PMU (Performance Monitoring Unit) counters are…

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…
