Arduino ☛ Meet Nuvi: the Hey Hi (AI) desk companion that goes from Q to cute
Luca Di Lorenzo (@LucaDilo on YouTube) recently worked with us on what was meant to be a simple robot assistant, but soon became something much more fun: a tiny, expressive desktop companion that notices you, listens to you, and talks back.

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 ☛ Fanless OnLogic controllers pair Core Ultra with CODESYS and fieldbus expansion
OnLogic has added two SoftPLC-oriented industrial computers built around defective chip maker 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 ☛ Digital Upgrade Brings Medium Format Camera Into The 21st Century
“Digital back” just means he’s replacing the rear of an existing film camera in order to put a sensor where said film used to live. The sensor is a 22 Megapixel Kodak KAF-22000CE, which measures in at a very respectable 38.8 mm by 50 mm. That’s only a touch smaller than the rolls of 120 the camera was designed for, whose large dimension was 56 mm. How much was exposed at a time was determined by the back you put on the camera, but would never have been below 41.5 mm. Again, the CCD is pretty close.

Digital Camera World ☛ A hacker built a modular “digital film” camera with a waist-level finder and interchangeable creation – and now he’s bringing this highly unusual camera to the masses
Built by camera hacker Malcom Jay, the WLV-01 is a modular camera built using Raspberry Pi with swappable sensors and a 3D-printed body and accessories. The camera can house a full-spectrum color or monochrome sensor, ranging in size from 1/1.2-inch to Micro Four Thirds, and can be paired with E-Mount or C-Mount lenses (Adapters also make it possible to shoot with vintage film lenses).

Hackaday ☛ ESP32 Replacement For Lighting Display Controller
As a company, NanoLeaf has been producing modular lights that can be easily snapped together into various geometric shapes for around a decade. Similar to the addressable LED light strips many of us are familiar with that also became popular around a decade ago, these modular lights are supposed to be easy to configure, customize, and program. But their controllers are notoriously finicky according to [Myrik] who found that a simple ESP32 could be used to replace them when they eventually fail.

William Pennings ☛ M&Ms and Skittles sorting machine
This project, the M&Ms and Skittles sorting machine, was on my to-do list for a long time. I finally managed to complete the project after working on it for several months in my free time. The machine uses an Arduino microcontroller, stepper motors, an RGB colour sensor and 3D-printed parts to sort several types of candy by their respective colours. The video below shows the machine in action.
