I built a mmWave material classification radar (2025)
Software is now a commodity thanks to Claude Code. So the next step is obviously hardware. I spent the last 6 months on building a hardware startup, which was fucking hard.

My favorite keyboards
When I started using computers, we had a Sinclair ZX Spectrum at home and a nano-reseau of Thomson MO5 s at elementary school. I distinctly remember how unpleasant it was to type with them. These must have been the worst keyboards I ever used [1] . Ever since, I have paid close attention to the keyboards I use. Here…

Framework's 10G Ethernet module exposes USB-C's complexity
I've been following WisdPi's development of various 5 Gbps and 10 Gbps Ethernet adapters for the past couple years. They use newer Realtek Ethernet chips, which sometimes have performance quirks—most frequently encountered under Linux. In today's video, I tested the new WisdPi 10G Ethernet Expansion Card for Framework…

The Xteink X4 E-Ink Reader
I’ve had the Xteink X4 for a couple of months now, a £40 e-ink reader small enough to stick to the back of a phone. I’d seen a few posts about it (Khairul Se...

My Steam Machine is a 50ft HDMI cable
It turns out that a _very_ long HDMI cable, a Steam Controller 2 and Bazzite on a second drive was all I needed to get a comfortable couch gaming experience.

Why Drawing Tablet Brands Won't Collaborate on Linux Floss Drivers
As you probably already know, I regularly get in contact with drawing tablet brands for reviews on my Youtube channel . I usually agree to do detailed video test of their models (see my hardware tag) but only at two condition: test the tablet on GNU/Linux, and only use Free/Libre and Open Source software for the test…

Cyberdecks, going analog, and convivial technology
People are moving away from corporate controlled tech, and making their own. How the designs of cyberdecks are being driven by women. And how medieval guilds, Luddites, and the Arts and Crafts movement are all connected to our current moment.

I Hate (Most) Keyboard 'Fn' Keys
Sometimes keyboards come with a 'Fn' key that allows some of their context-sensitive keys to do particular general-purpose functions. Sometimes these are implemented in careful, considerate and configurable ways... and other times they just make me want to throw the keyboard out of the window.

Ultrafast machine learning on FPGAs via Kolmogorov-Arnold Networks
This post is a high-level explainer for my Master’s thesis, which involves designing hardware architectures for ultrafast inference and online learning using the Kolmogorov-Arnold Network (KAN) architecture. I’ll assume familiarity with standard machine learning concepts, as well as some understanding of hardware and…

The intracies of modern camera lens repair (2024)
I stumbled across a broken Sigma 45mm f/2.8 Art lens for a very cool $58.65 USD that I simply could not resist. I've been eyeing an AF lens in the 50mm range for my recent endeavors with L-mount cameras and this looked like the perfect fit. This lens is commonly found as a kit with the very excellent full-frame Sigma…
