One day on my drive home, I saw three towers. One of them had a bunch of blinking white lights, another one had red lights that kind of faded in and out, and the third one, well, it wasn't doing anything. I'm lucky to have a radio engineer for a dad, so Dad:...

Возможно это провал: разгоняем до 400 герц

Стараясь держаться правила — одна статья в неделю — я, с красными глазами после работы, всё же закончил этот текст. Понимая, конечно, что в пятничный вечер его вряд ли кто-то прочитает. Но правило есть правило. Приятных вам выходных.

M5Stack PowerHub IoT Development Kit Integrates ESP32-S3 and STM32 Coprocessor

M5Stack has introduced the PowerHub, a compact IoT controller designed for distributed power and device management. The ESP32-based PowerHub is described as providing a stable and flexible control platform that integrates communication interfaces, modular power input options, and precise monitoring capabilities.

АМС-100Ф. «Народный» кассовый аппарат двухтысячных

Приветствую всех!

Когда-то давно я уже рассказывал про устройство и работу кассовых аппаратов с фискальной памятью.

Так уж вышло, что один из имевшихся у меня экземпляров я тогда так и не показал, хотя на самом деле его воистину можно назвать одним из символов касс той эпохи. Что же в нём такого примечательного? Сейчас и узнаем.

u-blox MAX-M10N GNSS module supports Low Energy Accurate Positioning (LEAP) mode, firmware upgrades

Following the launch of the UBX-M10150-CC low-power GNSS module, u-blox has expanded its lineup with the MAX-M10N, another ultra-low-power module based on the UBX-M10150-KB GNSS chip. The new module supports firmware upgradeability and offers up to 50% lower power consumption thanks to features such as Low Energy Accurate Positioning (LEAP) and PSMCT cyclic tracking modes. The latest SPG 5.30 firmware also adds support for RTCM correction input for sub-meter positioning accuracy, along with improved spoofing and jamming detection. It also includes data logging and geo-fencing for autonomous tracking and uses AssistNow Predictive and Live Orbits for faster satellite acquisition. The MAX-M10N...
