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…

I'm returning my Framework 16
My current laptop is an aging X1 Carbon generation 7, purchased some time in mid 2019. A few months ago a few keys of the keyboard stopped working, specifically the 5, 6, - , = and Delete keys.

Big GPUs don't need big PCs
Ever since I got AMD, Intel, and Nvidia graphics cards to run on a Raspberry Pi, I had a nagging question: What's the point? The Raspberry Pi only has 1 lane of PCIe Gen 3 bandwidth available for a connection to an eGPU. That's not much. Especially considering a modern desktop has at least one slot with 16 lanes of…

Pure Silicon Demo Coding: No CPU, No Memory, Just 4k Gates
In addition to the VGA donut , I submitted two other entries in the Tiny Tapeout 8 demo competition , where you submit a "tiny" ASIC design (room for about 4000 logic gates) that outputs 2-bit RGB to a VGA port and 1-bit audio to a speaker. One was a an old school C64/Amiga intro type of thing, and the other was a…

1.5 TB of VRAM on Mac Studio – RDMA over Thunderbolt 5
Apple gave me access to this Mac Studio cluster to test RDMA over Thunderbolt, a new feature in macOS 26.2. The easiest way to test it is with Exo 1.0, an open source private AI clustering tool. RDMA lets the Macs all act like they have one giant pool of RAM, which speeds up things like massive AI models. The stack of…

CM0 – A new Raspberry Pi you can't buy
This little postage stamp is actually a full Raspberry Pi Zero 2, complete with eMMC storage and WiFi. But you can't get one. Well, not unless you buy the CM0NANO development board from EDAtec, or you live in China. This little guy doesn't have an HDMI port, Ethernet, or even USB. It's a special version of the…
