ESP32-S31 development boards unveiled for IoT, Smart Audio, and HMI applications
Two ESP32-S31 development boards are currently in the works, and the documentation is already available. The ESP32-S31 was unveiled last March, and it’s the most feature-rich ESP32 wireless microcontroller so far with two RISC-V cores, Gigabit Ethernet, 2.4 GHz WiFi 6, Bluetooth, and 802.15.4 connectivity, LCD and camera interfaces, and more. The ESP32-S31-Function-CoreBoard-1 development board is based on the ESP32-S31-WROOM-3 wireless module, and offers Gigabit Ethernet, USB 2.0 OTG, and onboard audio peripherals for connected IoT applications. The ESP32-S31-Korvo-1 is a multimedia-focused development board based on the same ESP32-S31-WROOM-3 module, but featuring a dual-microphone array for speech recognition and near/far-field...
Дооснащение любительской электровакуумной мастерской. Вакуумметр, течеискатель, полярископ
Увы, электровакуумное дело, даже в его несложной любительской ипостаси, требует изрядного оснащения — приборы, материалы, инструменты, оборудование. К счастью, часть этого добра вполне возможно изготовить своими руками, если и не полностью заменив заводские аналоги, то, по крайней мере, получив инструменты более чем пригодные для домашних экспериментов. Здесь речь пойдёт о полярископе — несложном оптическом приборе, позволяющем увидеть и оценить внутренние напряжения в стекле и прозрачных материалах; простом приборчике для поиска течей в будущей вакуумной системе откачного поста [1]; вакуумметре до 10-3 мм рт. ст. на термопарной лампе-преобразователе ПМТ-2. Посмотрим, что и какими средствами удалось сделать, зачем эти приборы нужны и как работают.

Что детектировал детектор таксофонных карт?
Приветствую всех!
Осенью того года я однажды показывал начинку типичного карточного таксофона. Но, как нетрудно догадаться, самими аппаратами перечень такого оборудования не ограничивался. Сегодня мы поговорим об одной железке, напрямую к таксофону не подключавшейся, но имеющей к нему самое прямое отношение.
Зачем вообще была нужна эта коробочка и что она делает? Сейчас и разберёмся...

reComputer RK3576/RK3588 Edge AI computers are supported by reComputer AI Lab one-click deployment platform
Seeed Studio has just launched the reComputer RK3576/RK3588 Edge AI computers designed for developers, embedded AI innovators, robotics, industrial AI, vision AI, local LLMs, and real-world edge deployment. Rockchip RK3576 and RK3588 computers are pretty common these days, and the Seeed Studio models offer triple video output, dual Ethernet (GbE or 2.5GbE), several USB ports, and M.2 expansion. But the most interesting part is probably the software with Armbian-based Linux OS and support for the reComputer AI Lab platform that enables one-click deployment of AI-accelerated computer vision, audio, and LLM/LVM demos. reComputer RK3576/RK3588 specifications: SoC (one or the other) Rockchip...
