Valve's Steam Link now runs on Raspberry Pi 5 – excellent news for PC game fans who don't want to a lug a PC everywhere.
Cores are the new megahertz, at least for enterprise servers. We've gone quickly from 32, to 64, to 80, to 128, and now to 192-cores on a single CPU socket! Amazon built Graviton 4, Google built Axiom, but if you want your own massive Arm server, Ampere's the only game in town. And fastest Arm CPU in the world is…
Nothing says ‘80s pop’ like a DX7.
Engineered from the ground up to deliver immersive gameplay, fast content creation, and easy-to-use AI capabilities.
Photography is arguably my oldest hobby. I’ve loved taking photos for as long as I can remember. I reflected on my first encounter with digital photography in 2003 in a recent post, but I’m old enough…
tl;dr Raspberry Pi engineers tweaked SDRAM timings and other memory settings on the Pi, resulting in a 10-20% speed boost at the default 2.4 GHz clock. I of course had to test overclocking, which got me a 32% speedup at 3.2 GHz! Changes may roll out in a firmware update for all Pi 5 and Pi 4 users soon. My quest for…
How to program the Commodore 64 in BASIC, Assembly or C using Microsoft Visual Studio Code on Mac, Windows and Linux!
Today, we at SFC, along with our OpenWrt member project, announce the production release of the OpenWrt One. This is the first wireless Internet router designed and built with your software freedom and right to repair in mind. The OpenWrt One will never be locked down and is forever unbrickable. This device services…
To test if a display interface works we often don't want to use a huge framework like GTK or Qt. This article shows an easy way on how we can use a framebuffer directly on a DRM graphics driver under Linux.
Last year, I created Fake Parallel Printer , a tool to capture the output of the parallel printer port of old-ish test equipment so that it can be converted into screenshots for blog posts etc.
Seemingly, at the drop of a hat the morning of Friday, Nov 15th, Deye-branded inverters across the US were intentionally bricked.
New testing done at China’s Shidaowan nuclear power plant has confirmed its ability to be naturally cooled down, an industry-first milestone for achieving commercial-scale inherent safety, according to researchers.
1974 MIT Aluminum Bicycle Project, we describe some of Marc’s design, the frames he and Harriet built in Shawn Buckleys IAP course, and how these played a role in the Klein vs. Cannondale patent litigation in the mid-1980s.
The Raspberry Pi Compute Module 5 is smaller than a credit card, and I already have it gaming in 4K with an eGPU, running a Kubernetes cluster, and I even upgraded my NEC Commercial display from a CM4 to CM5, just swapping the Compute Modules! The Compute Module 4 was hard to get for years. It launched right after the…
There have been some past rumblings on the internet about a capacitor being installed backwards in Apple’s Macintosh LC III . The LC III was a “pizza box” Mac model produced from early 1993 to early 1994, mainly targeted at the education market. It also manifested as various consumer Performa models: the 450, 460…
A guide to the operating principles, techniques and technology in lidar systems for self driving cars.
I was studying the silicon die of the Pentium processor and noticed some puzzling structures where signal lines were connected to the silico...
A 192-channel phased array microphone, with FPGA data acquisition and beamforming/visualization on the GPU. Phased arrays allow for applications not possible with traditional directional microphones, as the directionality can be changed instantly, after the recording is made, or even be focused at hundreds of…

AlphaQubit is an AI-based decoder that identifies quantum computing errors with state-of-the-art accuracy.
The other day I saw the launch of Apple Vision Pro, the whole thing was very interesting, but one thing that caught my attention was the finger input. It seems very intuitive, by using the finger pinching as sort of like a cursor or mouse input. I figured I want to try it out, so I took it upon myself to create it.
Llama 3.1 405B on Cerebras is by far the fastest frontier model in the world – 12x faster than GPT-4o and 18x faster than Claude 3.5 Sonnet.

Today marks two years since I first set up an e-ink display in my mom’s apartment to help her live on her own with amnesia.
DeepComputing is excited to announce the launch of an exclusive early access program for the DC-ROMA RISC-V Mainboard, specifically designed for industry and business customers. This limited-edition initiative gives early adopters hands-on experience with premium, modular RISC-V development hardware, while their…
Last summer I got into cycling. I've long been a standing desk-er, and going out for long zone 2 rides and wondering what to think about made me wonder: could I work at a desk while I cycle?
I tried everything but couldn’t turn this Raspberry Pi 5 into the World’s Fastest Pi 5. Unfortunately, we can’t quite claim that title.
I had to pause some of my work getting a current-gen AMD graphics card running on the Pi 5 and testing a 192-core AmpereOne server to quickly post on the M4's efficiency. I expected M4 to be better than M1/M2 (I haven't personally tested M3), and I hoped it would at least match the previous total-system-power…
How we bypassed Apple's regulatory restrictions, built a Faraday cage and enabled georestricted features on the Airpods Pro 2 for our grandparents.
