Поднимаем сеть на коаксиальном кабеле в 2026 году

Приветствую всех!

Многие сейчас уже и не вспомнят, что такое «тонкий Ethernet», зачем компьютеру кабель, внешне похожий на телевизионный, и какими в своё время были компьютерные сети. И, признаться, те, кто не застал это всё, практически ничего не потеряли.

И вот как-то раз я задумался: а как насчёт попробовать связать пару компьютеров по такой сети уже в наши дни? Что из этого получится, и стоит ли вообще пробовать всё это? Сейчас и узнаем…

The accelerator delivers up to 40 TOPS of AI performance through the Ara-240 architecture, which integrates multiple neural […]

Raspberry Pi SBC gets (analog and) digital radio HAT with AM, FM, DAB, DAB+, HD radio

Yesterday, I wrote about a 2-year-old open-source hardware ESP32-based DAB+ receiver project, but it turns out there’s also a digital radio project for the Raspberry Pi that was released about three weeks ago. Raspiaudio’s Digital Radio V1 HAT adds AM/FM, DAB/DAB+, and HD Radio support to any Raspberry Pi SBC with a 40-pin GPIO header and is supported by CLI or web-based software for configuration and control.   Digital Radio V1 HAT specifications: Supported SBCs – Raspberry Pi Zero 1/2, Raspberry Pi 4/5, etc… Digital radio receiver chip – Skyworth Si4689-A10 (see product brief) Worldwide FM band support (76 to...

Open-source hardware DAB+ receiver combines ESP32 SoC with Skyworks SI4684 digital radio chip

When I wrote about a DIY ESP32-S3 internet radio last week, “raspbeguy” commented he’d rather choose an ESP32-based DIY DAB+ receiver kit, such as the one offered by the PE5PVB project based on a Skyworth SI4684 receiver. I first heard about DAB (Digital Audio Broadcast) in 2003 when we considered adding it to a CD player. It’s basically the digital equivalent of analog FM/AM radios, and I haven’t heard much about it since DAB and the “new” DAB+ standard are mostly a European story (see coverage map below). PE5PVB’s open-source hardware DAB receiver might still be worth a look. PE5PVB’s...

Sipeed T256s – A USB thermal camera with 256×192 LWIR sensor, 640×480 AI super resolution

Sipeed T256s is a portable USB thermal camera equipped with a native 256×192 Long-Wave Infrared (LWIR) sensor and a built-in 2.4 TOPS NPU for hardware-level AI super-resolution (ISR) up to 640×480 resolution in real time, effectively suppressing image noise without external software. The UVC camera device supports standard output (Y16 raw and MJPEG) and features both male and female USB Type-C ports on opposite ends for connection to PCs and smartphones. It also includes a 1.69-inch touchscreen for standalone operation with live viewing, palette switching, hotspot tracking, and image capture. Other features include an optional macro lens (~5 cm focus)...

RealSense ID Pro F500 Combines Depth Sensing and On-Device Biometrics

RealSense has introduced the RealSense ID Pro F500, a facial authentication module designed for access control, kiosks, and identity verification systems. The solution combines depth sensing, vision processing, and local computation to support secure biometric authentication without relying on cloud-based processing. The module integrates an active stereo depth system with a neural network pipeline for […]

Flash Bee – An ESP32-C3-based DIY handheld lightning detector

Flash Bee is an easy-to-make DIY handheld lightning detector based on off-the-shelf parts such as the XIAO ESP32C3 board and the Round Display for XIAO, as well as a 3D-printed enclosure. The design relies on the AMS AS3935 Franklin lightning sensor that’s been around for years, and found in kits like Sparkfun’s Arduino IoT weather station, which is capable of detecting lightning up to 40 km away with 1km accuracy. While it’s not quite new technology, I found the Flash Bee design to be rather cute and convenient, and it looks really easy to reproduce. Flash Bee key components: Seeed...

WeAct STM32U585CIU6 Core Mini – An $8 STM32U5 board supported by MicroPython v1.28

While checking out MicroPython v1.28 changelog, I noticed a board from WeAct Studio based on ST’s STM32U5 Cortex-M33 microcontroller: the WeAct STM32U585CIU6 Mini Core board (WEACTSTUDIO_MINI_STM32U585 in MicroPython code). I found it interesting/newsworthy, as while I had written about the initial STM32U5 MCU release in 2021, and followed up with beefier STM32U5 SKUs with NeoChrom 2.5D GPU and up to 4MB flash in 2023, we had yet to cover a third-party board based on an STM32U5 MCU, excluding the Arduino UNO Q SBC running Linux on a Qualcomm QRB2210 MPU and using an STM32U585 for real-time and I/O control. The...
