Linux 6.18 LTS release – Main changes, Arm, RISC-V, and MIPS architectures

Linus Torvalds has just announced the release of Linux 6.18 on the Linux Kernel Mailing List (LKML), which will likely become the next LTS kernel [update: it’s now official]: So I’ll have to admit that I’d have been happier with slightly less bugfixing noise in this last week of the release, but while there’s a few more fixes than I would hope for, there was nothing that made me feel like this needs more time to cook. So 6.18 is tagged and pushed out. Most of the last-minute fixes are minor fixes to drivers, with some random noise elsewhere (bluetooth,...

$9.99 2.5GbE PCIe adapter for Raspberry Pi 5 uses Realtek RTL8125 controller

Waveshare PCIe TO 2.5G ETH Board (C) low-cost PCIe x1 adapter adds a 2.5GbE port to the Raspberry Pi 5 using the board’s 16-pin PCIe interface. It’s plug-and-play and doesn’t require any additional drivers, making it a practical upgrade for DIY NAS, routers, or edge-networking applications. The board is built around a Realtek RTL8125 controller and offers a 10/100/1000/2500 Mbps RJ45 port with link/activity LEDs. It includes a transparent acrylic mounting plate at the bottom to save space above the board. It relies on a PCIe Gen2 x1 interface, takes 5V power through the PCIe cable or 5V power connectors,...

reComputer Mini J501 Provides Jetson AGX Orin Connectivity in a Reduced Footprint

The reComputer Mini J501 is Seeed Studio’s upcoming carrier board for NVIDIA’s Jetson AGX Orin module. Its 110mm × 110mm design offers a compact platform for robotics while retaining the connectivity needed for perception and control. The board supports the Jetson AGX Orin module, which integrates an Arm-based CPU cluster, Ampere GPU architecture, and dedicated […]

Name that Ware, November 2025

The Ware for November 2025 is shown below.

This one is hopefully a bit easier to guess compared to last month’s ware! Pictured is just one board of a two board set, but the second board is a bit too much of a dead give-away so it’s been omitted. Thanks to Sam for thinking on her feet and snatching this board so that it could be donated to the contest!

Winner, Name that Ware October 2025

Last month’s ware is an ADAS1010, described on the Analog devices website as a “15 Lead ECG Vital Signs Monitor Module with Respiration, Temperature and Blood Pressure Measurement”. It advertises a “robust, with electromagnetic interference (EMI), shock, and vibration resistant packaging”.

This is one of the more over-engineered solutions I’ve seen. I’m guessing that the middle layer of the three-layer stack is probably hollowed out, such that the surrounding boards create a Faraday cage. This would allow sensitive ECG front-end circuitry to be placed inside a shielded “container” that also doubles as a connector between the front and back boards.

SMHUB Nano Mg24 compact Linux-based Zigbee/Thread Smart Hub combines SG2000 RISC-V SoC with MG24 wireless MCU

SMLight’s SMHUB Nano Mg24 may look like the company’s earlier SLZB-06p Zigbee to Ethernet/WiFi/USB coordinators, but it’s a more powerful Linux-based Zigbee/Thread Smart Hub that pairs SOPHGO SG2000 RISC-V SoC with Silicon Labs MG24 multi-protocol wireless MCU. Unlike traditional Zigbee/Thread adapters that connect to a host through USB or Ethernet, the SMHUB Nano Mg24 is an all-in-one solution that runs all major automation apps directly on the device, eliminating the need for a Raspberry Pi, Mini PC, or other hardware server. SMHUB Nano Mg24 specifications: SoC – SOPHGO SG2000 CPU cores 1x C906 64-bit RISC-V core @ 1GHz or 1x Arm Cortex-A53...

Dual-Radio T-Lora Dual Supports LoRa at 150–960 MHz and 2.4 GHz

LILYGO has introduced the T-Lora Dual LR, a compact board that integrates an ESP32-S3R8 microcontroller with two LR1121 transceivers, combining Wi-Fi, Bluetooth LE, and LoRa across sub-GHz and 2.4 GHz bands. The module uses the ESP32-S3R8 as its main processor. It features a dual-core LX7 architecture and includes integrated wireless connectivity for Wi-Fi 802.11 b/g/n […]

Кустарные вакуумные триоды Клода Паяра. Часть 3. Установка ТВЧ

Продолжим обзор оборудования французского коллеги-энтузиаста Клода Пайяра, с его самодельным кустарным мини-производством триода ТМ [1] — первого серийного высоковакуумного прибора 1920-х годов, с невысокими (относительно прежних «ионных» газонаполненных ламп), но так нужными пользователю, стабильными параметрами. В части №1 мы познакомились с самим Клодом и его огневым оснащением, в части №2 рассмотрели простую технологическую мини-печь для отжига стеклянных деталей и аппарат для контактной сварки. Здесь же, мы взглянем на его установку ТВЧ — её создание и настройку.

Программирование для Windows 1.0 в 2025 году

«...Одним из примеров громоздкой и, по мнению авторов, бесполезной надстройки является интегрированная система WINDOWS фирмы Microsoft. Эта система занимает почти 1 Мбайт дисковой памяти и рассчитана на преимущественное использование совместно с устройством типа "мышь".» — вы точно знаете, откуда это

Приветствую всех! Буквально неделю назад прошло сорок лет с момента выхода первой релизной версии Windows. Именно в тот день в 1985 году началась история ныне повсеместно распространённой ОС.

И вот, узнав об этом, я подумал: а что, если попробовать запустить эту ОС и узнать, как предполагалось писать софт для неё? Именно этим мы сейчас и займёмся. Заодно и узнаем, насколько это было...

NET2 Line Leverages ESP32 to Bring Wireless ISA and PCI Connectivity to Modern Systems

ARS Technologies is developing a new product line that brings vintage ISA and PCI cards into modern computing workflows. The NET2 family builds on the company’s USB2 and XPRS series, adding wireless connectivity so legacy peripherals can be used from Linux, macOS, or current Windows systems. The NET2 series is based on an ESP32 module, […]
