Considerations for a long-running Raspberry Pi
Keeping a Raspberry Pi online and working with zero intervention for weeks, months, or years is somewhat of an art form. Several classes of things can go wrong, and you need to consider how your Pi will recover from each of them.

Fixing an Elgato HD60 S HDMI capture device with the help of Ghidra
This post has a little bit of everything. Hardware diagnostics, some suspiciously similar datasheets from two separate Taiwan chip manufacturers, and firmware reverse engineering. Read on if that sounds like fun!

Halo 2 in HD: Pushing the Original Xbox to the Limit
Everything I went through to add support for HD resolutions to Halo 2 on the Original Xbox. From patching the game's rendering engine and memory allocator, to hot patching the Xbox OS, to overclocking the GPU and running performance benchmarks. This post covers how I pushed the game and console to t

The Raspberry Pi 5 Is No Match for a Tini-Mini-Micro PC
I've always been fond of the idea of the Raspberry Pi. An energy efficient, small, cheap but capable computer. An ideal home server. Until the Pi 4, the Pi was not that capable, and only with the relatively recent Pi 5 (fall 2023) do I feel the Pi is OK performance wise, although still hampered by SD card performance…

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.

Carpentopod: A Walking Table Project
Back in 2008, I wrote some software for fun to generate various optimized walking mechanisms. And when I also picked up some electronics and wood working skills in more recent years, I was able to turn one of these mechanisms into an actual wireless walking wooden coffee table: the Carpentopod. This post briefly…

Tracker Beeper (2022)
A week ago, I finally got round to implementing an idea I’d been toying with for years: what if your computer made a little bit of noise every time it sent data to Google? From studying logs, I’d long known just how many sites send all your visits and clicks to (at least) Google, but a log that you have to manually…

What happens when you touch a pickle to an AM radio tower
A few months ago, our AM radio hot dog experiment went mildly viral. That was a result of me asking my Dad 'what would happen if you ground a hot dog to one of your AM radio towers?' He didn't know, so one night on the way to my son's volleyball practice, we tested it. And it was awesome. There's a video and some…

1/25-scale Cray C90 wristwatch
Welcome to the latest edition of my on-going series in Cray-related computational necromancy. This was another just-for-fun project. Over the many years Andras and I have been working on our Cray revival efforts, there has always been a big lag between our available software (and Andras’ amazing simulator ) and my…

Intel Honesty
The best way to both save Intel and have leading edge manufacturing in the U.S. is to split the company, and for the U.S. government to pick up the bill via purchase guarantees.

Breaking Free from DRM: Hacking My Air Purifier
I searched the web for a deal on a decent air purifier and the Xiaomi 4 Pro seemed to meet all my requirements. The filter size, scheduler and air volume ticked all the boxes. I set it up and thought nothing of it until last week my room was lit with the ‘ 0% remaining ’ replace filter warning. I had set my unit up to…
