DIN-rail mountable LoRaWAN control terminal offers RS485, analog input, and digital I/Os

The DFRobot LoRaWAN Control Terminal is a compact, DIN-rail mountable industrial IIoT terminal that features long-range LoRaWAN connectivity with local sensing and control capabilities. It’s designed for industrial, agricultural, and building-automation scenarios that need reliable, low-power wireless communication up to 4 km. The terminal supports the standard LoRaWAN protocol (OTAA/ABP, Class A/C) with up to 4 km line-of-sight range and works with private gateways or public networks like TTN. It integrates a 0–10V analog input, optically isolated digital inputs, and RS485/Modbus sensor support, along with a built-in relay output for direct actuation. There’s also support for visual rule-based automation for...

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...
