A while ago, our little one was born. As unfortunately her (great-)grandparents are located somewhat spread out over the globe, real-life visits can't happen too often. Obviously, video calling is a thing nowadays, so we keep in contact. Still, I wanted everyone to also be able to see her when we weren't online…
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…
Devices based on the i.MX8 or i.MX8M (such as the Librem phone or MNT Reform) have received popular coverage recently. The number of firmware blobs involved in the bringup of these devices is often a point of discussion. At times, people have considered whether some of these blobs could be replaced with libre…
David Patterson and team at UC Berkeley give RISC its name and make the first RISC microprocessor design.
13 vulnerabilities in GarminOS and the MonkeyC VM, 9 with CVEs, that let Connect IQ apps escape the VM and bypass permissions on 100+ Garmin watches.
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…
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. ……
How to stabilize digital supply voltages - and why most of the online advice on this topic is suspect.
This is a DS 3600 analog telephone made by Tesla Stropkov in about 1982. It's still functional and to my mind it's absolutely beautiful. Bu...
I’ve heard a lot about classic Doom’s data format and decided to write some Rust code to extract its maps and convert that to vector graphics I could laser cut.

Dmitry.GR: Driving a poorly-designed display and touch board using no CPU at all
While programmers today take division for granted, most microprocessors in the 1970s could only add and subtract — division required a sl...

A new paper describes how Google’s Cloud TPU v4 outperforms TPU v3 by 2.1x on a per-chip basis, and improves performance/Watt by 2.7x.
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.
Intel introduced the 8086 microprocessor in 1978. This processor ended up being hugely influential, setting the path for the x86 architec...
This week, I went to the tinyML Summit in Burlingame, Calif. TinyML, or running small machine learning models on constrained devices, is one of the most exciting technologies I’ve encountered. But it’s also the one most likely to put people to sleep when I talk about it. Using local computing to handle object or even…
The legacy of Intel's over-ambitious 32-bit 'micromainframe' failure.
I found this keyboard on eBay recently, although it wasn’t quite the one I was looking for I still think it is interesting. Let me show you why. This is the keyboard, and you would be forgiven for…
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…
After several years of development, complicated by the pandemic, disrupted supply chains, and war in Europe, we announced our new Original Prusa MK4 today. We began shipping the first units of the XL two weeks ago. There is an upcoming PrusaSlicer...
