Linux Gizmos ☛ wolfSSL adds post-quantum algorithms and AURIX TC4xx support alongside wolfIP
wolfSSL has detailed several embedded security updates covering deterministic networking, post-quantum cryptography and automotive hardware security. The updates include the wolfIP TCP/IP stack, NIST-validated post-quantum algorithms in wolfCrypt, native Falcon and FrodoKEM implementations, and wolfHSM support for Infineon’s AURIX TC4xx family.

Linux Gizmos ☛ 16-TOPS Hey Hi (AI) SBC with SATA 3.0 runs on octa-core Sophgo BM1688
Orange Pi has published hardware details for the OrangePi O1, a 90 × 70mm SBC based on the Sophgo BM1688 processor. It pairs eight Arm Cortex-A53 cores with a RISC-V C906 coprocessor and a 16-TOPS INT8 TPU, along with up to 16GB of LPDDR4/LPDDR4X memory.

Linux Gizmos ☛ Fanless OnLogic controllers pair Core Ultra with CODESYS and fieldbus expansion
OnLogic has added two SoftPLC-oriented industrial computers built around Intel Core Ultra processors and pre-configured CODESYS environments. The Helix 521-PLC targets low-profile deployments, while the larger Helix 524-PLC adds PCIe expansion with an available Hilscher netX fieldbus interface for industrial networking and real-time control applications.

Hackaday ☛ A Mini’s Infotainment System And The Joys Of Aftermarket Car Parts
Long story short, the device was mostly compatible aside from a connector wired wrongly and creating a short. This was fixed, but then the loosely fitted display toppled off during a test drive and broke, so a replacement screen was ordered. This screen arrived without requisite factory programming, so [Arkandas] embarked on a long reverse-engineering session.

Arduino ☛ Making retail smarter: build context-aware experiences with the Arduino® VENTUNO™ Q board
You step into a fitting room carrying two jackets and a pair of trousers. You like each piece, but you are not sure they work together – and which jacket is better. Normally, you would take a photo, message a friend, or walk back outside to ask a store assistant.

Hackaday ☛ Forget Trees, Add Fins To Your 3D Prints Instead
Perhaps one of the most contentious issues in 3D printing is that of supports, both because they’re an uncomfortable reminder of how gravity affects our prints and because the very idea of there being ‘one right way’ is bound to get you into some spirited discussions. That said, [Matthew Trahan] figured that neither regular grid supports nor organic tree supports are the answer here, and that the better answer is found in fins.

[Old] William Pennings ☛ Balancing cube
This cube manages to balance itself on a corner, and can simultaneously rotate around its axis in a controlled manner. It does so using clever controls and a set of three reaction wheels.
The original idea for this device comes from researchers at ETH Zürich, who demonstrate their “Cubli” in this video. Its design has been improved in some ways in later years. Notably, Bobrow et al (University of São Paulo) introduce an improved controls concept, reducing the number of required IMUs (inertial measurement units) to just one instead of six.

Hackaday ☛ Audio Spectrum Analyzer On An ESP32 Display Board
A slick spectrum analyzer used to be the kind of thing that would have been tricky to include in a DIY project, but as [Mirko “mircemk” Pavleski] demonstrates, a modern microcontroller like the ESP32 can handle the task with nothing more than a display panel and a few passives.

Android Police ☛ I replaced my Wi-Fi extender with an old Android phone after years of dead zones
I turned my old Honor phone into a full-time hotspot. I inserted a prepaid SIM card, subscribed to the appropriate data plan, and kept the phone plugged into its own electrical outlet.
