I built a special PCIe card to test GPUs on the Pi
I partnered up with Mirek (of Mirkotronics / @Mirko_DIY on Twitter) to build the Pi4GPU (or 'PiG' for short): This journey started almost three years ago: almost immediately after the Raspberry Pi Compute Module 4 was launched, I started testing graphics cards on it. First I tried some low-spec cards like the Zotac…

Windows on Btrfs
So for the past year and a half or so I've been using the fantastic Windows btrfs driver for easily sharing files between my Windows and Linux dualboot. The driver works great and basically fully supports everything that both operating systems could ever want (and let me tell you transparent compression and copy on…

Pico Cray – Small scale distributed computing
The Pico Cray is a cluster of 8 Picos and a controller Pico. All Picos are connected in parallel by an I2C bus. The controller is designated by one GPIO being held low, the processor Pico’s addresses are allocated automatically. The Controller Pico has a 320x240px display connected by SPI and a couple of buttons. ……

CAN Injection: Keyless car theft
This is a detective story about how a car was stolen - and how it uncovered an epidemic of high-tech car theft. It begins with a tweet. In April 2022, my friend Ian Tabor tweeted that vandals had been at his car, pulling apart the headlight and unplugging the cables.

SSD as Long Term Storage Testing
2022 September 10 What is the best media for long term storage is a question that I read frequently from online forums. First and foremost, as far as I’m aware there is no real “set it and forget it” long term storage. In this digital age, data needs to be validated regularly and cycled to a new media every 5-10 years…
