Linux Gizmos ☛ Tiny controller module has Cortex-M33, CAN FD, and Qwiic
Powering the BeagleConnect QuadESC motor-control board, the BeagleConnect Torque is an open-source controller module developed by BeagleBoard.org for robotics, industrial control, and connected sensing applications. Based on Texas Instruments’ AM13E23019 microcontroller, it features a 200 MHz Arm Cortex-M33 processor, CAN FD connectivity, and expansion interfaces for custom embedded systems.

Linux Gizmos ☛ Quad-motor control board with Cortex-M33 and TinyEngine AI
BeagleBoard.org has introduced the BeagleConnect QuadESC, an open-source four-channel brushless DC motor-control board for robotics, drones, and embedded applications. It integrates four three-phase power stages and the BeagleConnect Torque module, featuring a 200 MHz Arm Cortex-M33 processor, dedicated math acceleration, and a TinyEngine neural-network accelerator.

Hackaday ☛ A 3D Printed Marble Clock, But It’s Scrolling Text
Perhaps the most amazing thing about it is that it’s an absolutely massive structure, yet it’s all 3D printed and bolted together. It took a number of trial-and-error cycles, and debugging issues like the IR sensors getting confused by daylight, but it now mostly seems to work all right.

Hackaday ☛ Simple, Reliable RF Remote Control
Some of the first remote controls available to consumers used sound, visible light, or even just wires to communicate with their parent device. It was many years between these first rudimentary remotes before they standardized around infrared or RF signaling. Even then it was a while before remote controls were reliable enough to not have to think about anymore. They’ve gotten so good now that there are small modules available that let us quickly build these devices to perform all manner of tasks.

Hackaday ☛ An Analog TV Station For Anyone
If you’re a collector of older TVs, you’re probably facing the problem in some form of having no transmissions to tune in to. With many sets you can use a SCART or other A/V input, but nothing beats using the thing as it was intended. [BorisDigital] had exactly this problem, and since he worked in a TV transmitter control room in the 1990s, he’s made a small TV station that looks and operates like the real thing.

Geir Isene ☛ A mushroom's song
He built the instrument himself. Two electrodes in the stem of the mushroom. A small timer chip that turns the mushroom’s electrical resistance into a tone. A Raspberry Pi Pico that measures that tone 200 times a second. A laptop that turns the drift into notes in C minor pentatonic.
The mushroom is the only thing making the music. Left alone it plays some 20 notes a minute. Touch it and it plays a flurry. The idea comes from the open Biodata Sonification project, the same family as PlantWave.

Slurp Burgers ☛ the slurptop | slurpburgers.com
With the form factor decided on, the next step in every project I do is to gather up all the components, grab my calipers, and get to measuring and modeling in Blender. I make "good enough" 3d models of EVERYTHING. It's tedious and time consuming, but I wouldn't do it any other way. You can package everything so much nicer when using this method, and you run into WAY fewer problems during the assembly stage, WAY fewer redesigns and reprints, etc. This is the "measure twice" process when building a device like this, even though it's more along the lines of "measuer ten thousand times". Very worth it, and I highly recommend approaching things from this direction. Not to mention you're honing your ability to measure and model things, which is invaluable as a desinger.
