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...

Easily create an ESP32-C5 dual-band Wi-Fi analyzer

Chen Liang (陳亮) has found an interesting use case for the Espressif ESP32-C5: a dual-band Wi-Fi analyzer showing the signal strength of 2.4 GHz and 5 GHz WiFi access points in your area. It works like one of the Wi-Fi analyzer apps on your phone, except it relies on an ESP32-C5 board and a display support for the Arduino_GFX libraries, for example, based on the ILI9341 driver, as it’s easier for beginners since the code does not need to be changed. Here’s what it looks like. You can follow the instructions provided by Chen to reproduce the setup. It’s fairly straightforward....

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...
