Argon Industria PoE+ HATs add 25W Ethernet power and optional NVMe to Raspberry Pi 5

Argon40 has introduced two Industria PoE+ HATs for the Raspberry Pi 5, providing power and data through a single Ethernet cable using the IEEE 802.3af/at PoE+ standard. Both boards deliver up to 25W output, supplying 5V/5A for full operation. The standard Argon Industria PoE+ HAT focuses on single-cable power and network connectivity, while the Argon […]

MSI MS-CF27 3.5-inch SBC with Alder Lake-N, quad GbE, and triple display

Following earlier platforms such as the MS-CF16 V3.0 and MS-CF19, MSI has introduced a new 3.5-inch SBC based on Intel Alder Lake-N, Twin Lake-N, and Amston Lake processors, continuing its focus on fanless, low-power, wide-voltage embedded systems with expanded connectivity and I/O. Processor options include the Intel Processor N97, Core i3-N305, Amston Lake x7433RE, and […]

Universal TFT Display Backpack 2

This is an updated version of my Universal TFT Display Backpack, a microcontroller board based on an ATtiny814 that can accommodate a range of different Adafruit and AliExpress colour TFT displays:

an AliExpress 3.5" 480x320 TFT display.

It's ideal as the basis for applications based on my TFT graphic libraries. 

Like the earlier board Universal TFT Display Backpack it has the following features:

SBC Clusters are a terrible value, but they're fun anyway

Pictured above is the new DeskPi Super4C installed in an 8U mini rack. The Super4C is a 4-node Raspberry Pi CM5 cluster board that solves two pain points I had with the older Super6C.

I was testing this board around the same time I helped kick off the SBCC 2026, the Single Board Cluster Competition for students. A dozen or so university teams squared off to run the best mini HPC cluster with a budget of $6,000, and a couple days to benchmark six HPC workloads.

Электровакуумные геттеры. Бариевые газопоглотители

Взглянув чуть более внимательно на изготовление электронных ламп — нехитрых в сущности приборов, с прискорбием выясняется неутешительное — нагрев и пониженное давление превращают привычные, казалось бы, надёжные и незыблемые материалы, натурально, в предателей и прохвостов, так и норовящих подложить свинью и испортить лампу [1]. И только последовательная тщательная и большая подготовительная с ними работа и длительное маринование электровакуумных приборов (ЭВП) на откачном посту заставляет внутренние металлы, стекло, слюду ламп держаться приличий. Если подготовка и очистка, дело неизбежное, то длительную (иногда до суток и более!) откачку ламп на громоздком, сложном, дорогом и энергоёмком оборудовании позволил фантастически сократить некрупный специальный элемент внутри колбы прибора — газопоглотитель, иначе — геттер.

Являясь местным миниатюрным одноразовым высоковакуумным насосом, он поглощает остатки газов, сокращая...

Палиха П-750. Последний телефон с АОН двухтысячных

Приветствую всех!

Когда-то давно, когда стационарный телефон имелся практически в каждой квартире в крупном городе, стали набирать популярность аппараты с определителем номера. Были они очень у многих, с ними связано много воспоминаний, про них спустя годы было написано немало статей, ну а для кого-то бизнес на их сборке вообще стал возможностью пережить тяжёлые девяностые.

В двухтысячные годы такие девайсы начали потихоньку уходить в историю, заменяясь импортными моделями с Caller ID. Один из последних таких аппаратов мы сейчас и рассмотрим.

Сегодня мы посмотрим, что умеет и как устроен самый топовый городской телефон той эпохи. Заодно узнаем, зачем подключать телефонный аппарат к компьютеру и можно...

Raspberry Pi Connect may control Windows soon

Support for remote controlling Windows PCs may be added to Raspberry Pi Connect, Raspberry Pi's free remote access service.

When they announced Pi Connect in 2024, I speculated the service was launched in response to RealVNC's sluggish adoption of Wayland, leading to Pi users lacking a solid remote access solution after Pi OS 12 'Bookworm' was launched.

The service was helpful for those who had one or more Raspberry Pis to access, but the Pi Connect daemon didn't run on Windows or macOS at the time, so a true competitor to RealVNC (at least for basic use cases) it was not.

Name that Ware, April 2026

The Ware for April 2026 is a little bit different. Instead of showing a circuit board, I thought it’d be interesting to go inside the chips themselves and try to identify what’s happening on at the silicon level.

Since chip reading isn’t a widely spread skill, we’ll start with a gentle introduction. For this series of wares, I’ll tell you exactly which chip these images are from: they’re from the Baochip-1x. It’s unique in that at least some of the source code is available – enough of it to give significant hints as to what’s going on. It’s also unique in...

Winner, Name that Ware March 2026

The Ware for March 2026 is a Elecom DST C30SV 6 in 1 USB “docking station”. I’ll give the prize to tayken – the ware itself wasn’t terribly hard to guess on its own, so this month I’m just going with the first interesting response. Congrats, email me for your prize!

As other readers commented, the device has a lot of similarity to other products in this class. I’m guessing there is a common board design that OEMs use to make variants of the product.

Here’s additional context of the ware, for completeness!

This one claimed to have “PD” capability, such that one...
