Palm-sized Mini PC NAS offers four M.2 bays and dual 2.5GbE ports
Youyeetoo has introduced the NestDisk, a compact mini-PC NAS built around Intel’s Alder Lake-N architecture. The system integrates four M.2 NVMe slots in a chassis similar to an external drive enclosure, targeting home lab, soft routing, and media server deployments. The device is powered by the Intel Processor N150, a quad-core CPU within the Alder […]
PSoC Edge E84-Based Handheld Runs RT-Thread for Local Machine Learning
RT-Thread has launched a Crowd Supply campaign for the Edgi-Talk, a handheld reference platform built for hardware-accelerated machine learning. Based on Infineon’s PSoC Edge E84 architecture, it targets smart home, wearable, and industrial interfaces that rely on local inference and responsive voice interaction. The core of the system is the Infineon PSoC Edge E84, which […]

Кустарные вакуумные триоды Клода Пайяра. Часть 4. Вакуумные насосы
Мы уже познакомились с Клодом Пайяром — французским радиолюбителем, в бытность, редактором журнала Radio-REF, энтузиастом-электровакуумщиком, воссоздавшим в своей мастерской кустарное производство практических триодов ТМ [1] (первых, 1920-х годов, промышленных «жёстких» — с высоким вакуумом, электронных ламп), и рассмотрели его самодельное огневое оснащение (Часть 1), установку для контактной сварки и технологическую печь (Часть 2), ламповую установку ТВЧ для дегазации электродов ламп при откачке (Часть 3). Сегодня мы взглянем на высоковакуумную установку Клода, самодельную, как и всё его оборудование.

Приветствую всех!
Давным-давно, ещё в советскую эпоху, большинство лифтов были релейными. Но уже в восьмидесятые начали появляться электронные станции. Конечно, до современных микропроцессорных систем им было очень и очень далеко, а построены они были на дискретной логике. Тем интереснее взглянуть на устройство таких блоков.
Так получилось, что ко мне в руки попала одна из таких станций управления. Так что сейчас у нас есть возможность посмотреть, как она устроена, и попробовать разобраться, как она работает. Традиционно будет много интересного.

The RAM Shortage Comes for Us All
Memory price inflation comes for us all, and if you're not affected yet, just wait.
I was building a new PC last month using some parts I had bought earlier this year. The 64 Gigabyte T-Create DDR5 memory kit I used cost $209 then. Today? The same kit costs $650!

Why doesn't Apple make a standalone Touch ID?
Why doesn't Apple make a standalone Touch ID?
I finally upgraded to a mechanical keyboard. But because Apple's so protective of their Touch ID hardware, there aren't any mechanical keyboards with that feature built in.
But there is a way to hack it. It's incredibly wasteful, and takes a bit more patience than I think most people have, but you basically take an Apple Magic Keyboard with Touch ID, rip out the Touch ID, and install it in a 3D printed box, along with the keyboard's logic board.
...HackRF Pro Receive Sensitivity and Noise Figure
In the HackRF Pro specifications we’ve mentioned improved RF performance compared to HackRF One. Now that we’ve finalized any last tweaks to the RF front-end and production is well underway, we’d like to share some more details about the improvements.
One key metric for radio systems is sensitivity, which measures the minimum signal strength that a receiver can detect. However, for software defined radio hardware, sensitivity is difficult to define in a useful way as it changes depending on the modulation scheme in use and even the software implementation.
Instead we can look at noise figure: this measures the degradation in signal-to-noise...
