The RK3572 uses a heterogeneous CPU arrangement consisting of a dual-core Cortex-A73 cluster, […]
ESP32-S3 boards feature WAGO connectors for LED strips, buttons, other swappable modules

Rev Adrian Kennard (RevK) has designed several open-source hardware ESP32-S3 WiFi and Bluetooth IoT boards with WAGO connectors for interfacing LED strips, buttons, and other GPIO modules. Initially developed for the gloves and the helmet of an Iron Man suit, the ESP32-S3 boards can be used for any relevant project that needs more flexibility than soldered modules and more reliability than GPIO headers or even screw terminals, which can be susceptible to vibrations. WAGO push-in connectors make the ESP32-S3 boards especially suitable for prototyping and wearables, where being able to quickly swap modules is beneficial. The first board designed for...

Anthropic’s open-source Claude Desktop Buddy turns ESP32-S3 devices into interactive AI desk companions

Anthropic has opened its Claude Hardware Interface (Bluetooth API) to developers, enabling an ESP32-S3-based desk companion to connect directly to the Claude desktop app over Bluetooth Low Energy (BLE). To demonstrate this new feature, the company released an open-source reference project called Claude Desktop Buddy. It currently runs on the M5StickC Plus (an ESP32-based board from M5Stack, about $30 on AliExpress and Amazon) and works as a small interactive hardware companion for Claude. Also, during the recent “Build with Claude” event, the company recommended the ESP32-S3-based M5Stack Cardputer as one of the best hardware options for developers who want to...
PENOX WristBuds – A Bluetooth 6.0 smartwatch with integrated TWS earbuds (Crowdfunding)

PENOX WristBuds is a 2-in-1 rugged Bluetooth 6.0 smartwatch with integrated TWS earbuds, eliminating the need for a separate charging case. Designed for outdoor enthusiasts and the “zero-clutter mobility” market. The watch is built around a Bluetrum AB5681G RISC-V smartwatch MCU managing both the smartwatch interface and audio synchronization. The device sports a large 2.1-inch IPS display with a 320×390 resolution and is housed in a CNC-machined zinc alloy body. But what’s interesting about this is its mechanical, spring-loaded “Pop & Snap” design that houses the TWS earbuds inside the watch, and eliminates the need for a separate charging case....
Радио почти из ничего. Самодельные радиодетали 1920-х. Детекторы

В продолжение путешествия к истокам радио (самодельные резисторы 1920-х [1], самодельные конденсаторы 1920-х [2]) мы с тобой, дорогой читатель, обратим свой взгляд на тогдашние детекторы — важнейший элемент любого долампового радио, выделяющий из радиочастотных колебаний звуковой сигнал. Какие же существовали материалы и конструкции детекторов, пригодных для изготовления скудными средствами среднестатистического энтузиаста-любителя радио? Чем последнего, в этом смысле могла порадовать отечественная промышленность? Во времена, когда ещё не существовало готовых фабричных элементов-полупроводников, когда самым сложным инструментом в арсенале радиомастера, вероятнее всего, мог быть простой электрический паяльник, да и само сетевое электричество водилось не во всяком доме.
