Not all OCuLink eGPU docks are created equal
I recently tried using the Minisforum DEG1 GPU Dock with a Raspberry Pi 500+, using an M.2 to OCuLink adapter, and this chenyang SFF-8611 Cable. After figuring out there's a power button on the DEG1 (which needs to be turned on), and after fiddling around with the switches on the PCB (hidden under the large metal…

YouTube audio quality – How good does it get? (2022)
You Tube is clearly used by a very large number of people. In general, they will be interested in watching videos of various types of content. One specific purpose is that it gets used to distribute, and make people aware of, audio recordings. A conversation on the “Pink Fish” webforum devoted to music and audio set…

The Arduino Uno Q is a weird hybrid SBC
The Arduino Uno Q is... a weird board. It's the first product born out of Qualcomm's buyout of Arduino. It's like if you married an Intel CPU, and a Raspberry Pi RP2040 microcontroller—oh wait, Radxa's X4 did that. Arduino even tried it before with their old Yún board, which had Linux running on a MIPS CPU, married to…

NVIDIA DGX Spark In-Depth Review: A New Standard for Local AI Inference
Thanks to NVIDIA’s early access program, we are thrilled to get our hands on the NVIDIA DGX™ Spark. It’s quite an unconventional system, as NVIDIA rarely releases compact, all-in-one machines that bring supercomputing-class performance to a desktop workstation form factor.

Resizeable Bar Support on the Raspberry Pi
While not an absolute requirement for modern graphics card support on Linux, Resizeable BAR support makes GPUs go faster, by allowing GPUs to throw data back and forth on the PCIe bus in chunks larger than 256 MB. In January, I opened an issue in the Raspberry Pi Linux repo, Resizable BAR support on Pi 5. Unlike most…

Exploring Dithering on Spectra 6-color E-Ink Displays
I have tested the XIAO ePaper DIY Kit (ESP32-S3) – EE04 from Seeed Studio in depth. While its 6-color Spectra 6 display is impressive out of the box, I wanted to see if software could overcome hardware limitations. In this post, I’ll share how I’ve pushed this hardware to its limits by using dithering techniques to…
