TerraMaster F2-425 Plus NAS review – Part 2: Configuration, benchmarks, and AI-enhanced media storage

I received the TerraMaster F2-425 Plus 3+2 Hybrid NAS for review last month, and after checking out the hardware in the first part of the review, I’ve finally had time to test the Intel N150 NAS. After installing two 4TB SATA drives and an M.2 NVMe SSD, I’ll report my experience setting up the system with the TNAS Android app, before running some benchmarks, and testing features like photo backup with AI search capabilities. Hard drive installation I already had an old, but little-used, 4TB HGST SATA drive, and I bought a “new” 4TB SATA drive online for a pretty...

Introduction to the PineTime Pro

How is your day/night going RSS readers? In this blog post we go in depth on the new PineTime Pro hardware and share some pre-production information from JF.

Bring back MiniDV with this Raspberry Pi FireWire HAT

In my last post, I showed you to use FireWire on a Raspberry Pi with a PCI Express IEEE 1394 adapter. Now I'll show you how I'm using a new FireWire HAT and a PiSugar3 Plus battery to make a portable MRU, or 'Memory Recording Unit', to replace tape in older FireWire/i.Link/DV cameras.

The alternative is an old used MRU like Sony's HVR-MRC1, which runs around $300 on eBay1.

FOOF. Воспроизводим легендарный баг в процессоре Pentium

Приветствую всех!

Думаю, при упоминании знаменитого бага в процессоре Intel Pentium на ум сразу приходит ошибка деления. Но, как оказывается, она была не единственным косяком этих чипов.

Первые «пеньки» имели ещё одну интересную особенность: существовали «роковые» четыре байта, выполнение которых заставляло компьютер зависнуть намертво. Что же это была за ошибка, как она проявлялась и как её воспроизвести? Сейчас и узнаем.

SparkFun Thing Plus – ESP32-C5 board offers dual-band WiFi 6, Adafruit Feather pinout, LiPo battery support

Espressif has recently released the ESP-IDF v6.0 framework with support for ESP32-C5 and ESP32-C61, so we can expect more ESP32-C5 boards. Following the launch of boards like DFRobot FireBeetle 2 and the Espressif DevKitC-1, SparkFun has now launched its Thing Plus – ESP32-C5, an Adafruit Feather-compatible board based on the ESP32-C5. The timing is no coincidence. Although the ESP32-C5 dual-band WiFi 6 SoC was announced back in 2022, hardware makers have been waiting for stable software support. With the release of ESP-IDF v6.0, the ESP32-C5 moves from “preview” to “stable” and adds key features, such as Safe Bootloader OTA updates. This...

ESP32-P4-Pi-VIEWE – A Raspberry Pi-inspired ESP32-P4 + ESP32-C6 board with Ethernet, USB, 40-pin GPIO header, and more

The ESP32-P4-Pi-VIEWE is a Raspberry Pi-inspired development board equipped with a VIEWE ESP32-P4C6-Core module, combining a 400 MHz ESP32-P4 dual-core RISC-V MCU with an ESP32-C6 chip for Wi-Fi 6 and Bluetooth 5.0 wireless connectivity, as well as 32MB PSRAM and 16MB NOR flash. The board also offers 10/100Mbps Ethernet connectivity, MIPI DSI, and CSI connectors for display and/or camera, two onboard microphones, a speaker output, a USB 2.0 port, a micro SD card slot, and the usual 40-pin GPIO header, all in a familiar 85 x 56 mm credit card form factor. ESP32-P4-Pi-VIEWE specifications: Main module – VIEWE ESP32-P4C6-Core Microcontroller...

Радио почти из ничего. Самодельные радиодетали 1920-х. Конденсаторы

Мы уже припомнили [1], насколько небогато жилось коллегам-любителям на заре радио, и каков облик имели нехитрые рукодельные и даже фабричные радиоприёмники 1920-х — простые детекторные или малоламповые схемы, как правило — для длинных и средних волн. Скудный ассортимент всего из нескольких универсальных триодов, не ломившиеся от радиотоваров полки магазинов — почти все элементы для своих конструкций приходилось изготовлять своими руками, часто начиная от нехитрых материалов — листовых металлов, фольги и проволоки, дощечек, винтов, гвоздей, кое-каких подножных кухонных химикатов и прочей чепухи. Изготовлять в том числе и элементы питания (накальные элементы, анодные батареи), резисторы-конденсаторы, детекторы, выпрямители (в случае наличия осветительной сети), сердечники трансформаторов...

Microchip SAM9X75 Hybrid automotive MCU – Surprisingly ARM9 is still a thing in 2026

When Microchip launched the SAM9X60 in 2020, we were surprised to see a new SoC based on a legacy ARM926EJ-S core. But we were even more surprised to see Microchip doubling down with the SAM9X75, a hybrid automotive-qualified (AEC-Q100 Grade 2) System-in-Package (SiP) with the same classic ARM9 core and integrated DDR2 or DDR3L memory. The first part will be the SAM9X75D5M SiP with 512MB on-chip DDR2 RAM, but the company also designed the SAM9X75D1G with 1 Gbit DDR3L and the SAM9X75D2G featuring 2 Gbit DDR3L. The SAM9X75 hybrid ARM9 MCU targets developers who need an MCU-like development environment, while...
