• Linux Gizmos ☛ MSI WS300 with 72-Core Grace CPU, Blackwell Ultra GPU, and Dual 400GbE

  MSI has detailed the XpertStation WS300T60L, a tower workstation based on NVIDIA’s DGX Station architecture and GB300 Grace Blackwell Ultra platform. The system is aimed at Hey Hi (AI) development, data science, inference, Hey Hi (AI) agents, and physical Hey Hi (AI) workloads, with a 72-core Arm processor, Blackwell Ultra GPU, up to 748GB of coherent memory, and dual 400GbE connectivity.

• Tom's Hardware ☛ Hardware modder builds overclocked PS3 ‘Pro’ v3 with 3D-printed cooling mod — dual Noctua fans and server heatsinks provide FPS boost in 'almost every game'

  A Sony PlayStation 3 console modder has shared images and details of their faster, cooler, and quieter ‘PS3 Pro v3’ design.

• CNX Software ☛ USB-C Deskradar – An ESP32-C3 ADS-B flight tracker with a 1.28-inch round display

  The USB-C Deskradar is an ESP32-C3-based, aviation-themed ADS-B flight tracker that tracks and displays live aircraft positions around your location on a sonar-style circular grid. A 1.28-inch round display and a 3D-printed enclosure provide a real-time view of flights around a configured location.

• Arduino ☛ Blue Proton Initiative: four 17-year-olds are building [slop]-powered livestock monitoring with Arduino

  Pietro Maria Piazza, Alessandro Nesci, Davide Santucci, and Matteo Angiolillo are not waiting to finish school before starting to build something real.

• CNX Software ☛ Opener is an open-source reference implementation of the DECT NR+ massive IoT, low-latency standard

  Opener is an open-source reference implementation of the DECT NR+ protocol stack, formally known as DECT-2020 NR, used for massive IoT (mMTC) and low-latency (URLLC) machine-to-machine communication applications. It is developed by the Opener Initiative, supported by the OpenDECT-X project, and funded by the German Federal Ministry of Research, Technology and Space (BMFTR). The standard itself supports up to one million devices per km², years of battery life for low-power sensors,  non-IP and IPv6 traffic, mesh networking, and random-access operation.

• Hackaday ☛ Analog Optical Feedback Generates 4K Fractals With No Computer

  Physically this build is very similar to the “God Machine II” sculpture we covered previously, which in turn built on the first 720p version of his art piece. Getting analog video feedback in HD was hard enough — you need to be able to adjust the hue, saturation, brightness and contrast of the monitor as you go in order to have the full control of the resulting image. Most old TVs had those back in the SD era, but once HD came around it was rare; [The Light Herder] despaired of ever finding a screen that would to this in 4K.
