The (almost) perfect mini NAS for my mini rack

The (almost) perfect mini NAS for my mini rack

The GMKtec G9 N150 4-bay NVMe mini PC is $240 and the nearly perfect NAS for my mini rack:

It has an Intel N150 4-core SoC with halfway-decent Intel UHD integrated graphics, 12 GB of LPDDR5 RAM, dual 2.5 Gbps Ethernet, WiFi 6, and the best part: 4 integrated M.2 NVMe slots.

Granted, splitting up the 9 PCIe Gen 3 lanes limits the performance a bit, but there are some things I love about this design:

Автомашинист. Навигатор для локомотива

Приветствую всех!
Все мы знаем, что во время движения поезда машинисту следует учитывать кучу параметров вроде профиля пути, временных ограничений скорости, опасных мест и тому подобного. И было бы странно, если бы до сих пор не была придумана система, позволяющая информировать его об этом. Как оказалось, такая штука действительно есть, и мне удалось заполучить на опыты один экземпляр.
Итак, сегодня поговорим про такую штуку как система информирования машиниста. Заодно запустим её, посмотрим на девайс в работе, а также узнаем, что ещё умеет этот блок. Как водится, будет много интересного. Читать дальше →

Thin PoE HAT for Raspberry Pi 5 features isolated SMPS, fits inside the official case, works with the active cooler

Waveshare has launched the PoE HAT (H), a thin Power over Ethernet(PoE) HAT for the Raspberry Pi 5 that easily fits inside the official case and works with the active cooler. The HAT is specially designed for the Raspberry Pi 5 and supports IEEE 802.3af/at PoE standards. It features an isolated switched-mode power supply (SMPS) that delivers a stable 5V/5A output through the GPIO header.  The board includes a standard 40-pin GPIO header and relies on a low-profile PoE IC. Waveshare PoE HAT (H) Specifications: Compatibility – Raspberry Pi 5 Expansion – 40-pin Raspberry Pi GPIO header Cooling Fits inside the...

Avaota F1 – A tiny camera board based on Allwinner V821 RISC-V SoC with built-in WiFi and 64MB DDR2

The Avaota F1 is an ultra-small, open-source hardware Linux SBC powered by an Allwinner V821 32-bit RISC-V camera SoC with 64MB on-chip DDR2 and built-in 2.4 GHz WiFi 4, and designed for camera applications with a MIPI CSI connector. The 35×22 mm board also features a 32MB NOR flash, an analog microphone, a USB-C port for power, data, and programming, two 15-pin GPIO headers, a FEL button, and a user LED. It looks like it will be offered as a development kit with a 1080p30 camera and a 3.5-inch or 1.54-inch SPI display. I also think it’s the first time...

LaserPecker LP5 Review – Part 2: A 20W diode & fiber laser engraver tested with LDS software, rotary extension, safety enclosure

We have already checked the specifications, done an unboxing, and shown how to assemble the LaserPecker LP5 2-in-1 fiber & diode laser engraver along with its safety enclosure and rotary extension in the first part of the review. In the second part of the review, we will report our experience using the LaserPecker LP5 laser engraver with various materials such as plywood, stainless steel, rubber, and aluminum, as well as a ceramic cup and an insulated tumbler using either the LDS software on Windows or the LDS mobile apps on an iPad. Using the LaserPecker LP5 laser engraver with LDS...
