PwrBlock 323 is an open-hardware USB-C power supply that provides software-controlled voltage and current for automated testing, hardware-in-the-loop setups and lab applications. Finnish company Everypin has introduced PwrBlock 323, a programmable power supply designed to be integrated directly into automated test fixtures. The device provides a single non-isolated output from 1 to 32 V at […]

Comma AI, the company behind open-source automated driving software, just announced the Chestnut — an eGPU dock with open-source firmware that costs $249 bare. The announcement hit 55 points on Hacker News, and it represents something genuinely new in the external GPU dock market. What Makes Chestnut Different External GPU docks (eGPU enclosures) have existed for years, but they've always been ex…

Earlier this year, leaders at Amazon Web Services delivered a new mandate to their engineers: They need to conserve CPU cycles at all costs. AWS has reportedly experienced an explosion in wait times for CPU server capacity as AI workloads strain the company’s cloud infrastructure. The issue seemingly took AWS off guard, and for good reason. The AI boom led to a surge in demand for GPUs and, later…

Researchers from Princeton University published a technical paper titled “Hardware Mechanisms to Dynamically Throttle AI Performance.” Abstract Excerpt: “In this paper, we introduce a set of microarchitecture knobs which dynamically control the available hardware resources to limit AI performance at runtime. We evaluate candidate knobs spanning the GPU memory subsystem, across capacity, bandwidth…

This paper proposes a high-speed hardware accelerator for QR-UOV, a multivariate scheme, that executes all three operations: key generation, signature generation, and signature verification. QR-UOV utilizes a quotient polynomial ring structure to reduce the public-key size of the original UOV scheme; however, this introduces functional requirements distinct from other multivariate schemes, such a…

You know that weekend project idea that stalled because the dev board was bigger than the thing you wanted to hide it inside? A wearable, a keyfob mod, a sensor tucked into a bottle cap? The pinch from moddo is the board that finally makes those builds realistic. A whole Arduino the size of a USB-C plug moddo calls the pinch "the world's smallest 32-bit Arduino-compatible board," and while nobody…

I like my new-to-me MacBook because it enables me to create more stuff compared to my now almost 8 year old Thinkpad I had before, mainly due to battery and screen reasons. There is one thing about it that I cannot wrap my head around from a design perspective and it’s the sharp edges especially around the wrist area. On a flat surface it’s no problem at all, but low and behold a laptop will be f…

Snappy performance, long battery life, great keyboard and excellent new haptic touchpad make the best of Windows 11 Microsoft’s Surface laptop for consumers is back, faster and with longer battery life and a hefty price increase because of the high cost of memory and chips. The Surface Laptop 8 is a straight replacement for the seventh edition from 2024, which was the first of Microsoft’s new gen…

The AI hardware landscape has shifted significantly in 2026, with NVIDIA, AMD, and Intel all competing for developers who need GPUs capable of running local large language models and AI inference workloads. Choosing the right GPU for AI workloads requires looking beyond marketing numbers and focusing on the specifications that actually affect real-world performance. Memory capacity, memory bandwi…

The recent end-of-financial-year sales were rather interesting – I found myself spending a lot more time browsing AliExpress than I did Amazon or eBay this year which is something I wouldn’t have envisioned in the past. I suppose the deals offered by the others just weren’t that good. While AliExpress was dangling cashbacks and coupons, I decided to make the most of it and buy some things that I …
