2.1-channel audio HAT for Raspberry Pi features Texas Instruments TAS5825M class-D amplifier

Previously, we wrote about the Louder Raspberry Pi, an open-source media center that integrates the Louder Raspberry Hat based on a 25W TAS5805M Class-D amplifier. Now, the developer has introduced the Louder Raspberry Hat Plus, upgrading from the TAS5805M amplifier to the more powerful TAS5825M, capable of driving up to 53W in mono (PBTL) mode while offering improved efficiency and thermal performance. The Louder Raspberry Hat Plus is compatible with all Raspberry Pi models and comes in 1X and 2X variants. The 1X version delivers up to 2×32W at 8Ω or 2×45W at 4Ω, the 2X version, on the other...

Кустарные вакуумные триоды Клода Пайяра. Часть 5. Конструкция лампы

Продолжим знакомство с работой современного французского энтузиаста-электровакуумщика Клода Пайяра [1], воссоздавшего в своей мастерской кустарное микропроизводство ранних высоковакуумных триодов — варианта легендарного ТМ [2]. Ранее мы уже рассмотрели его огневое оснащение [1], технологическую печь, контактную сварку [3] и ламповый аппарат ТВЧ [4], полюбопытствовали, чем Клод откачивает свои лампы [5]. С воображаемой лупой в руках посмотрим же, как устроен его вариант триода, чем он похож и чем отличается от исторических прототипов; по характерным примерам последних проследим часть эволюции этой выдающейся лампы.

MediaTek Genio 360/360P hexa/octa-core Cortex-A76/A55 AIoT SoC features 8 TOPS NPU for cost-sensitive embedded applications

MediaTek Genio 360 and Genio 360P are respectively hexa-core and octa-core Arm Cortex-A76/A55 AIoT processors featuring a MediaTek NPU delivering up to 8 TOPS of AI performance, and designed for cost-sensitive embedded applications. The chips support up to 8GB of memory and eMMC 5.1, SPI NOR, and SD 3.0 storage interfaces. They feature two 4-lane MIPI DSI and one 4-lane DP/eDP interfaces for single or dual display setups, two 4-lane MIPI CSI camera interfaces, audio inputs/outputs, Gigabit Ethernet with TSN, optional WiFi 5 and Bluetooth 5.3 via MT6631N, USB 3.1 and USB 2.0 interfaces, PCIe Gen2 x1, and low-speed interfaces....

Что на самом деле показывал индикатор частоты ЦП на корпусе?

Приветствую всех!

Когда-то давно тут уже рассказывали про кнопку Turbo и про замок на корпусе ПК. Самое время вспомнить ещё один неотъемлемый атрибут компьютеров тех лет: индикатор частоты процессора.

Казалось бы, это до невозможности банальная штука, не сложнее индикатора питания. Но всё оказалось не так уж просто и даже у этого устройства иногда можно было найти много интересного. Давайте разбираться...

Fanless Factor 101 Arrives with Qualcomm QCS6490 and 10GbE Networking

OnLogic has introduced the Factor 101, a compact fanless industrial system built around Qualcomm’s QCS6490 platform. The unit targets edge deployments that need wired networking, basic display output, and local inference acceleration in a small enclosure. The platform is based on an 8-core Qualcomm Kryo 670 CPU clocked at up to 2.1GHz, paired with 8GB […]

ESP32 Bus Pirate Update Adds RF Tools, USB Host Mode, Signal Analysis, and Cellular Plans

The ESP32 Bus Pirate project, originally introduced as a modern ESP32-S3 adaptation of the classic Bus Pirate debugging tool, has received a substantial update expanding its protocol support, signal analysis capabilities, and RF experimentation features. The original Bus Pirate is an open-source hardware tool widely used for communicating with and debugging embedded systems over interfaces […]

GStreamer 1.28 Adds AI Inference Engines, YOLO Decoders, and Tensor Auto-Discovery

Collabora has announced GStreamer 1.28, expanding its machine learning and AI inference capabilities for media pipelines. The release adds new inference engines, broader tensor decoder support, improved metadata handling, and tooling aimed at simplifying object detection, classification, and segmentation workflows on embedded Linux systems. Support for ONNX Runtime has been improved, including a refactor from […]

MediaTek MT7902 wireless chipset finally gets a Linux driver

MediaTek MT7902 wireless modules are used in many Windows laptops, but so far, a Linux driver has been missing. This is about to change, as Mediatek has finally committed a patchset for MT7902 to the mainline Linux mailing list. This is personal. I bought an ASUS Vivobook 16 in August 2023, and Ubuntu 22.04 worked pretty well out of the box, except for support for the Wi-Fi 6E and Bluetooth module, detected as “Network controller: MEDIATEK Corp. Device 7902” with lscpi but without working drivers. Since then, I’ve been using the laptop connected to the USB dock with Ethernet support...

Free Stuff - September 2025

The belated September 2025 recipient for the Great Scott Gadgets Free Stuff Program is Ashen Chathuranga, a university student from Sri Lanka. He is working on a project involving the development of an open source satellite monitoring station and requested a HackRF One to conduct his research. He will also be researching radio wave penetrating materials for his university. Being able to assist students in need of equipment for academic research and goals is one of our primary goals for our Free Stuff Program, so we are happy we were able to help Ashen out!

Free Stuff - October 2025

The belated October 2025 recipient for the Great Scott Gadgets Free Stuff Program is Alex Barnes, who applied on behalf of Amateur Radio and Electronics Society (QUB_ARES) at Queen’s University Belfast! Alex has informed us that they are an academic society primarily focused on running regular educational events around radio and electronics. So far they have run lessons and training for their members to get UK Foundation Amateur Radio licenses, worked with a local Scouts group for Jamborees on the Air, and she ran a series of events last year where she demonstrated using an SDR and a few 433...
