Linux Gizmos ☛ Grinn GenioBoard Offers MediaTek Genio 700 SoM, Dual M.2 Expansion, and CRA-Ready Security
Grinn has unveiled the GenioBoard, a compact single-board computer aimed at accelerating development of embedded and AI-enabled systems. It integrates the company’s GenioSOM-510 and GenioSOM-700 modules built on MediaTek’s Genio processor family, combining multiple Arm Cortex-A cores with an integrated GPU and NPU for edge inference applications.

Arduino ☛ Building a custom Arduino-controlled 'analog' dashboard
Those new gauges indicate fuel level and coolant temperature. They have moving needles and look like they’re analog, but they’re actually digitally controlled by Arduino boards. Small hobby servo motors move the needles according to readings taken by a float sensor and a temperature sensor, gathered by an Arduino Nano Every board through its analog pins.

Arduino ☛ 3D printing a stunning silver mechatronic beetle necklace
Katz and Harrigan made this at a hackathon that Formlabs hosted, so they were able to take advantage of the available printers, resins, and in-house casting expert. The necklace features a large silver beetle resting on a pair of leaves designed to lay across the wearer’s sternum. When the beetle detects heat, such as from a person approaching, it opens its wings to reveal a colorful array of LEDs like stained glass on its thorax, while it wiggles its antennae.

The Radiant Computer Team ☛ Radiant Computer
Computers today are designed around engagement and surveillance business models rather than user needs. App stores are filled with adware. Operating systems prioritize data collection over user agency. Social media algorithms optimize for addiction. Big Tech fundamentally reshaped computing from a tool for human empowerment into an attention extraction machine.
Radiant proposes an alternative vision for computing. It doesn't ship with a web browser; it has its own network reminiscent of the early Internet: no social media, no scripts, no trackers. It's a from-scratch system that doesn't retrace the footsteps of the contemporary OS. It's a new paradigm for personal computing that uses modern advances mindfully and deliberately. It's fully open, from hardware to software. It's an offline-first space, designed for focus and creation.

Six Colors ☛ I’ve upgraded my house’s holiday lights for the last time
This is when I decided that if we’re in for a penny, we’re in for a pound. Permanent holiday lights. Could it be done?
My goals were the ability for me to install them myself, for them not to be too expensive, and for them to last. Not the cheap stuff from Amazon, but professional-grade systems designed to last. Ideally, the lights would also be programmable so that they could serve us throughout the year, not just during the holidays.
