The module is designed for embedded and industrial systems requiring multimedia processing, machine vision capability, and edge inference support. The platform integrates four Arm Cortex-A53 cores operating up to 1.8 GHz alongside a Cortex-M7 real-time core […]

GEEKOM A5 Pro 2026 Edition Review – Part 3: Ubuntu 25.10 on an AMD Ryzen 5 7530U mini PC

After checking out the hardware with an unboxing and a teardown of the GEEKOM A5 Pro 2026 Edition mini PC, and testing it with the pre-installed Windows 11 Pro OS in the second part of the review, we will now report our experience with Ubuntu 25.10 to show how the AMD Ryzen 5 7530U mini PC performs under Linux. The Ubuntu 25.10 review includes an overview of the system, benchmarks, storage and networking (2.5GbE and WiFi 6) performance testing, and measurements of CPU temperature under stress, fan noise levels, and power consumption of the mini PC under various workloads. Ubuntu...

A PTP Wall Clock is impractical and a little too precise

After seeing Oliver Ettlin's 39C3 presentation Excuse me, what precise time is It?, I wanted to replicate the PTP (Precision Time Protocol) clock he used live to demonstrate PTP clock sync:

I pinged him on LinkedIn inquiring about the build (I wasn't the only one!), and shortly thereafter, he published Gemini2350/ptp-wallclock, a repository with rough instructions for the build, and his C++ application to display PTP time (if available on the network) on a set of two LED matrix displays, using a Raspberry Pi.

Echo Pyramid enables smart voice interaction applications on M5Stack Atom ESP32 IoT controllers

Designed for M5Stack Atom, AtomS3, and AtomS3R series IoT controllers based on ESP32 or ESP32-S3 wireless SoC, the Echo Pyramid base enables smart voice interaction applications such as far-field voice recognition, voice assistants, voice control, and more. The device features a built-in speaker, a MEMS microphone, an ES8311 HD audio codec for playback and capture, and an STM32 MCU for touch areas and RGB LED management. It’s powered via a USB Type-C port and can be expanded through a 4-pin connector for I2C modules. Echo Pyramid specifications: Supported IoT controllers – M5Stack Atom, AtomS3, and AtomS3R Microcontroller –  STMicro STM32G030F6P6...

Стеклодувное дело. Электровакуумные стёкла, идентификация стекла, экспресс-определение совместимости стёкол

Известно, что сортов стекла превеликое множество, и каждый из них обладает собственным набором характеристик. Среди прочих, каждой марке (рецепту) стекла присущ и такой важный параметр, как коэффициент теплового расширения (КТР)*, показывающий насколько стекло расширится при нагревании или сожмётся при остывании. Понятно, что жёсткое соединение (спаивание) двух стёкол, возможно, только в случае совпадения их КТР или очень близких их значений, в противном случае спай при остывании обзаведётся недопустимыми, коварными и непредсказуемыми, неустранимыми никаким отжигом, внутренними напряжениями, или вовсе разрушится, иногда с разлётом осколков. КТР указан в названии каждой марки электровакуумного стекла на бирках крупных коробок, однако, сами трубки и стержни никак не маркируются, в стеклодувной мастерской их обязательно приходится хранить системно и...

DFRobot launches low-power, low-cost Fermion: BMV080 air quality sensor module

Just last year, we reported on the SparkFun Air Quality PM1/PM2.5/PM10 Sensor, based on the Bosch BMV080 fanless air-quality sensor and priced at around $65. DFRobot has now launched a low-cost alternative, the Fermion: BMV080, which provides the same fanless, laboratory-grade PM1, PM2.5, and PM10 sensing capabilities for just $29.90. The sensor uses laser-based light-scattering technology with fanless optical counting to detect particles as small as 0.5 μm. This avoids fan noise, dust buildup, and mechanical wear, which are common with fan-based PM sensors, and, on top of that, it has a service life of up to 10 years. It measures...

КП-74. Валидатор советской эпохи

Приветствую всех!

Уверен, даже если вы и не застали транспорт той эпохи, вы всё равно узнаете эти устройства — билетные компостеры. Если кассы ушли в историю значительно раньше, то вот они продержались много дольше, вплоть до конца девяностых, а кое-где и до двухтысячных.

Итак, сегодня мы взглянем на прямого предка электронных валидаторов. Посмотрим на тройку самых распространённых моделей и на то, как они устроены и как они кодировались, и разберёмся, как менялись эти девайсы со временем.

WiFi and Bluetooth LE can now be used simultaneously on Arduino boards with NINA-W102 (ESP32) module

Today I learned that WiFi and Bluetooth LE could NOT be used simultaneously on Arduino boards featuring the ESP32-based u-blox NINA-W102 wireless module, impacting the Arduino Nano RP2040 Connect, Arduino MKR WiFi 1010, and Arduino Nano 33 IoT boards. It’s a long-running problem since the first Arduino board with NINA-W10 was introduced in 2018, and meant you could use WiFi or Bluetooth LE, but not both simultaneously. The good news is that the issue has finally been fixed, thanks to a new firmware for the module and new WiFi and BLE libraries. More specifically, you’ll need the following libraries and...

STM32U3B5/C5 ultra-low-power MCU features 640 KB RAM, 2 MB Flash, and HSP accelerator to run AI without batteries

STMicroelectronics has added two members to the STM32U3 ultra-low-power Arm Cortex-M33 microcontroller family: the STM32U3B5 and STM32U3C5 MCUs get more resources with up to 640 KB SRAM and 2 MB flash, as well as an HSP (hardware signal processor) accelerator to run AI/ML workloads without batteries, just using energy harvesting. The new chips are still clocked at up to 96 MHz, benefit from a near-threshold design (down to 0.65 V), allowing a power consumption of just 117 Coremark/mW in active mode, and can operate up to 105°C ambient temperature. They come with one additional group of interfaces, bringing the total...

Plantower vs Sensirion — вскрываем лазерные датчики пыли

Ну штош. В этот раз о «железках».
Если вы когда-нибудь делали DIY-датчик воздуха — почти наверняка использовали датчики Plantower 5003 или Novafitness SDS011. Но сегодня мы вскроем Plantower PMS7003 и Sensirion SPS30.
