FreeBSD doesn't have Wi-Fi driver for my old MacBook, so AI built one for me
My old 2016 MacBook Pro has been collecting dust in a cabinet for some time now. The laptop suffers from a “flexgate” problem, and I don’t have any practical use for it. For quite some time, I’ve been thinking about repurposing it as a guinea pig, to play with FreeBSD — an OS that I’d aspired to play with for a long…

Upgrading an M4 Pro Mac mini's storage for half the price
A few months ago, I upgraded my M4 Mac mini from 1 to 2 TB of internal storage, using a then-$269 DIY upgrade kit from ExpandMacMini. At the time, there was no option for upgrading the M4 Pro Mac mini, despite it also using a user-replaceable, socketed storage drive. But the folks at M4-SSD reached out and asked if…

Why movies look weird at 48fps, and games are better at 60fps
Let’s end this debate once and for all. Humans can see frame rates greater than 24fps (although plenty of people will argue that they can’t on the internet). I’ll explain more in a future post if necessary, but let’s take that as read.

How Taalas “prints” LLM onto a chip?
A startup called Taalas , recently released an ASIC chip running Llama 3.1 8B (3/6 bit quant) at an inference rate of 17,000 tokens per seconds. That's like writing around 30 A4 sized pages in one second. They claim it's 10x cheaper in ownership cost than GPU based inference systems and is 10x less electricity hog…

Driver adventures for a 1999 webcam
We generally know that when we buy a piece of technology that it will not last forever, connectors wear out and/or go out of fashion. But I think the most frustrating reason to have to get rid of something is that drivers stop being made for devices.

Pure Silicon Demo Coding: No CPU, No Memory, Just 4k Gates
In addition to the VGA donut , I submitted two other entries in the Tiny Tapeout 8 demo competition , where you submit a "tiny" ASIC design (room for about 4000 logic gates) that outputs 2-bit RGB to a VGA port and 1-bit audio to a speaker. One was a an old school C64/Amiga intro type of thing, and the other was a…

Reverse engineering a car key fob signal
I’ve had the curiosity to explore radio communication protocols for a few years now, ever since I’ve started fiddling around with an RTL-SDR dongle. I always had the goal of figuring out how data is transmitted in remote controls (car key fobs particularly), trying replay attacks, and other possible attack vectors.

The Raspberry Pi Has Revolutionized Emulation
Every geek goes through a phase where they discover emulation. It’s practically a rite of passage. I think I spent most of my childhood – and a large part of my life as a young adult – desperately wishing I was in a video game arcade. When I finally obtained my

Do I really need to get out the soldering-iron again?
So I had this idea that it would be nice to listen to music when I get home from work everyday, so I put all my ripped music onto my phone, and I bought some good quality over-ear headphones.

Fixing a bricked Framework laptop
My experience fixing my Framework 13” laptop with AMD 7060 series that was bricked due to a failed BIOS update with US$20 worth of tools, instead of replacing the motherboard as suggested by Framework support.

iMac G4(K)
A year ago I tried using an M1 iMac for work duty but its 21" screen took up too much room on my desk. After seeing Sean's video on Action Retro about putting an M4 Mac Mini inside an iMac G4 , I thought I'd give it a try.
