CNX Software ☛ Toradex OSM and Lino SoMs – 30×30mm NXP i.MX 93/i.MX 91 modules with solder-down or B2B connector designs
Toradex has launched two new ultra-compact (30x30mm) System-on-Module (SoM) families: OSM and Lino, powered by NXP i.MX 91 or i.MX 93 Arm Cortex-A55 SoC for Edge industrial and IoT applications. The OSM iMX91 and OSM iMX93 variants comply with the OSM Size-S standard, featuring a 332-ball contact grid designed to be soldered to the carrier board.

Between 2019 and 2021, Low-tech Magazine published three books containing selections of articles from the website, spanning 14 years (2007-2021). In 2024, we launched the “compressed edition”, which squeezes the article catalog of the three-volume book series into just one book of 620 pages.

Linux Gizmos ☛ Seeed Studio reTerminal D1001 Targets HMI Systems with ESP32-P4 and Integrated Display
Seeed Studio has launched an 8-inch HMI device combining a touch display, wireless connectivity, and multimedia hardware in a single platform. The reTerminal D1001 pairs an ESP32-P4 with an ESP32-C6 for networking, along with a 6-axis IMU for motion sensing.

The Register UK ☛ Raspberry Pi leans into semiconductors as sales climb
The latter statistic might cause concern among the hobbyist community, who would otherwise be delighted at the company's success. While the $66.3 million gross profit from the company's SBC and compute modules was far in excess of the $0.6 million from "Microcontrollers, publishing and others," the company has an "ambition to build Raspberry Pi into a two‑franchise business, with both electronic products and semiconductors making significant contributions to volumes, revenues, and profitability."
Alex Pugh, an analyst at Freetrade, commented: "What's interesting is the business is starting to look broader and more industrial. Semiconductor shipments overtaking boards and modules for the first time is a meaningful milestone. Raspberry Pis are moving out of garages and workshops into elevators, moving walkways, industrial control and automation, digital signage, smart buildings, and energy management.

Hackaday ☛ Reverse-Engineering The Holy Stone H120D Drone
There are plenty of drones (and other gadgets) you can buy online that use proprietary control protocols. Of course, reverse-engineering one of these protocols is a hacker community classic. Today, [Zac Turner] shows us how this GPS drone can be autonomously controlled by a simple Arduino program or Python script.

Hackaday ☛ LED Matrix Clock Proudly Shows Its Inner Wiring
The exception is the four MAX7219 LED matrices whose faces are hidden behind a featureless red panel, and for good reason. As soon as the clock powers up, the LEDs shine through the thin red plastic in a clean glow that complements the rest of the clock nicely.

Hackaday ☛ Improving FDM Filament Drying With A Spot Of Vacuum
Keeping your filament safely away from moisture exposure is one of the most crucial aspects of getting a good 3D print, with equipment like a filament dryer a standard piece of equipment to help drive accumulated moisture out of filament prior to printing or storage. Generally such filament dryers use hot air to accomplish this task over the course of a few hours, but this is not very efficient for a number of reasons. Increasing the vaporization rate of water without significantly more power use should namely be quite straightforward.
The key here is the vapor pressure of a liquid, specifically the point at which it begins to transition between its liquid and gaseous phases, also known as the boiling point. This point is defined by both temperature and atmospheric pressure, with either factor being adjustable. In a pressure cooker this principle is for example used to increase the boiling temperature of water, while for our drying purposes we can instead reduce the pressure in order to lower the boiling point.

Arduino ☛ SomnoSphere is an intelligent bedside lamp that helps you sleep better
Ferus-Comelo built SomnoSphere around an Arduino® UNO™ Q. It monitors a whole suite of sensors. Of those, two are particularly interesting: a DFRobot C1001 60GHz mmWave sensor and an MLX90640 infrared thermal camera. Those enable SomnoSphere to see your body and determine if you’re awake, in REM sleep, or in deep sleep. The other sensors let SomnoSphere monitor room conditions, like temperature, light, and noise.
