The kit is built around the Cardputer-Adv core unit and the Cap LoRa-1262 expansion module, and comes preloaded with Meshtastic firmware for out-of-the-box operation. The Cardputer-Adv is a card-sized programmable device based on […]

AMD Versal Prime VM2152 mid-range adaptive SoC features 112 Gbps GTM Transceivers, 600Gbps Ethernet, DDR5/LPDDR5

The AMD Versal Prime VM2152 adaptive SoC is designed as a mid-range device for high-speed connectivity, with 112 Gbps transceivers and 600 GbE networking in a power-efficient package. It balances programmable logic with hardened IP blocks to simplify the design of high-throughput systems used in wired communications, aerospace, and test and measurement, without the higher power and complexity of high-end FPGAs. Compared to the AMD Versal Prime VP1902, the VM2152 focuses more on I/O performance rather than raw logic density. While the VP1902 offers more logic cells, the VM2152 adds support for LPDDR5 memory up to 6400 Mb/s and includes...

Banana Pi BPI-OM7 AI 3D camera pairs BPI-M7 RK3588 SBC with ORBBEC Gemini 2 depth camera

Banana Pi BPI-OM7 is an AI 3D depth camera that combines Banana Pi BPI-M7 low-profile Rockchip RK3588 SBC with an ORBBEC Gemini 2 depth camera, targeting applications in 3D vision, robotics, edge AI, and spatial perception. The solution ships with 8GB of RAM and a 64GB eMMC flash by default, offers HDMI and USB-C video outputs, dual 2.5GbE networking, and a few USB ports. It’s mounted on a tripod for convenience. Banana Pi BPI-OM7 specifications: SoC – Rockchip RK3588 octa-core processor with CPU – 4x Cortex‑A76  cores @ up to 2.4 GHz, 4x Cortex‑A55 core @ 1.8 GHz GPU –...

Prunt Board 3 3D printer control board offers smoother and quieter operation (Crowdfunding)

Prunt Board 3 is a 3D printer control board with six TMC2240 stepper drivers, two 15A heater outputs, four fan outputs, four thermistor inputs, and four endstop inputs that is designed to offer smoother and quieter operation. The hardware is said to offer better ESD protection than boards such as the Duet 3 Mini 5+ or BTT SKR 3 EZ and supports hardware-accelerated step generation, but the magic happens with the Prunt firmware and associated server, which enable a 31-phase velocity profile for smoother operation and higher-quality prints compared to boards running Klipper or Marlin firmware. Let’s have a look...

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...

ESP-FLY DIY Kit is a tiny ESP32-S3-based DIY micro drone kit

ESP-FLY DIY kit is a miniature DIY drone kit based on Seeed Studio’s XIAO ESP32-S3 board that was initially introduced as a DIY project on Instructables by Max Imagination, but is now available as a complete kit for $59.99 on Seeed Studio. It’s certainly not the first ESP32 drone, but the ESP-FLY drone must be the smallest, as the miniature (67 x 67 x 31mm) quadcopter design allows users to store into any pocket or small boxes. It’s mainly designed for STEM education,  hobbyist DIY Projects, and indoor flight practice. ESP-FLY drone kit key features and specifications: Main Controller –...

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...
