Autonomous Submarine Relies On Color Detection
https://invidious.privacyredirect.com/watch?v=_M3SRvy68w8
We talk about all kinds of autonomous vehicles here at Hackaday, from aerial drones to rugged rovers. A little less common are the submarine builds, likely due to their technical complexity. That said, though they perhaps benefit most from autonomy given they’re so hard to talk to while underwater. In any case, [Ayman] has built an impressive sub that uses some rudimentary techniques to navigate around while under the surface.
The build uses typical construction techniques for DIY subs of this size, with a clear acrylic tube serving as the body of the craft. It’s carefully sealed to ensure water ingress...
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.

Huion Note E is an Android 15 note-taking device/electronic notebook powered by a MediaTek Helio G99 SoC and equipped with an 8.4-inch color LCD designed to work with a battery-free PenTech 3.0 pressure-sensitive stylus. The device ships with 6GB LPDDR4 memory, 128GB storage, and a single USB-C port for charging and data. The company says the 1920×1080 display leverages “AG nano-etching technology to create a refined, matte surface that mimics the traditional pen-on-paper experience” and provides an e-Paper-like experience, while maintaining a 60 Hz refresh rate. Huion Note E (X50) specifications: SoC – MediaTek Helio G99 CPU – Octa-core processor...
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...

Flipper One – A Rockchip RK3576-powered portable Arm Linux computer and networking multi-tool
Flipper Devices has officially introduced the Flipper One open-source hardware portable Arm Linux platform and networking and Edge AI multi-tool powered by a Rockchip RK3576 octa-core Arm Cortex-A72/A53 SoC, and featuring a Raspberry Pi RP2350 for low-level control. You may think of it as a successor to the popular STM32-based Flipper Zero hardware and wireless hacking tool, but the company stresses that the Flipper One is NOT a replacement for the Flipper Zero. It is a different product with mainline Linux kernel support, no binary blobs (probably not 100% true), and open-source drivers, and operating at a different level of...
