Работа с художественным стеклом. Часть 2. Упрощённые светильники

Имея малую долю художественных навыков или даже просто «чувства прекрасного» с толикой терпения и усидчивости, своими золотыми можно делать удивительные вещи, тем более что современные технологии и материалы позволяют, например, легко работать с такой сложной субстанцией, как стекло, даже не слишком подготовленным барышням и школьникам. Речь пойдёт о небольших декоративно-прикладных работах из цветного стекла, и двух простых вариантах светильников на их основе. Светильники на основе витража, тоже демонстрируют работу из стекла на просвет, но по сравнению с витражами классическими — мобильнее, проще адаптируются в обстановку, легко заменяются и не зависят от внешнего освещения. В части №1 мы рассмотрели светильник-ящик, при...

«Чтоб никто не дозвонился»: как работает аппаратура защиты таксофона

Приветствую всех!
В прошлый раз я уже рассказывал, как устроен и как работает современный карточный таксофон и какими методами защиты он обладает.

Но оставался ещё один блок, который я тогда так и не упомянул. К моему удивлению, в интернете не так много информации по тому, как он устроен и как работает. Именно о нём мы сейчас и поговорим, а заодно и узнаем, как и от чего он вообще защищает.

Windows 95 made to run on ESP32-S3 hardware with Tiny386 x86 PC emulator

He Chunhui (hchunhui) has developed the Tiny386 x86 PC emulator in C (C99) and managed to run Windows 3.1/3.2 and Windows 95 on an ESP32-S3 devkit with a 3.5-inch display. We had already seen Linux 5.0 boot on an ESP32 board, and Olimex ESP32-S3-DevKit-LiPo run a more recent Linux 6.3 image, but I think it might be the first time somebody has loaded Windows on ESP32 hardware. Bear in mind that since the Tiny386 is an emulator running SeaBIOS, it can also boot the Linux kernel directly. He Chunhui explains that the i386 CPU emulator is built from scratch and...

Qualcomm launches Dragonwing IQ-X SoCs for industrial Windows PCs

The Qualcomm Dragonwing IQ-X family, comprised of the IQ-X7181 and IQ-X5181 SoCs, offers eight or twelve Oryon cores clocked at up to 3.4 GHz, an Adreno GPU, and up to 45 TOPS of AI performance for industrial PCs running Windows LTSC. Those are upgrades to the Dragonwing IQ9/IQ8/IQ6 SoCs introduced last year, offering faster cores, higher speed interfaces, and more. The IQ-X chips support up to 64GB LPDDR5x memory, UFS 4.0 and SD 3.0 storage, eDP and USB-C display interfaces, up to six cameras, PCIe Gen4 connectivity for optional Ethernet, WiFi 7, and 5G cellular connectivity, and feature eleven USB...

All Intel GPUs run on Raspberry Pi and RISC-V

All Intel GPUs run on Raspberry Pi and RISC-V

We finally have Intel Arc GPUs working on the Pi somewhat stably—it required overcoming many small hurdles, but it looks like support could land in Raspberry Pi OS if we can get a simple patch upstreamed1. If that happens, all you'd need to do to use an Intel card on a Pi is install a firmware package.

The cards I've spent the most time with so far are:

Arduino Nesso N1 – An ESP32-C6 IoT wireless development kit with WiFi 6, BLE, 802.15.4, LoRa, and IR transmitter

Arduino Nesso N1 is a new ESP32-C6 IoT development kit with not only 2.4 GHz WiFi 6, Bluetooth LE, and an 802.15.4 radio for Zigbee/Thread/Matter, but also a LoRa radio and an IR transmitter for smart home, industrial, and educational applications.

Kyocera triple lens AI depth camera enable recognition of thin and semi-transparent objects, wires

Kyocera has unveiled a triple lens AI depth camera capable of recognizing semi-transparent, thin, and fine line-shaped objects that are difficult to detect with the human eye and traditional stereo cameras. The camera can accurately measure the distance to and size of objects which are between 0.3 and 1mm thick, and is expected to be useful in robots for manufacturing, medical applications, and Smart Agriculture. Preliminary specifications: Sensors Left-center, center-right, and left-right cameras Focus distance – About 10 cm Proprietary AI combining multiple parallax data sets from the sensors Ideal for Thin, irregularly shaped linear objects, such as harnesses or...

Arduino Nesso N1 Debuts as a Compact RISC-V IoT Controller with Wi-Fi 6, Thread, and LoRa Connectivity

Arduino has released the Nesso N1, a compact IoT controller developed with M5Stack and built around the ESP32-C6. The device integrates a touch display, onboard sensors, and multiple wireless protocols inside a small enclosure aimed at rapid prototyping and portable embedded applications. The system is built around Espressif’s ESP32-C6 microcontroller, a single-core 32-bit RISC-V processor […]

4-inch UGOOS AC1 smart clock features Amlogic A213Y SoC for smart displays and digital signage

UGOOS is better known for its TV boxes, but the company recently introduced a different product with the AC1 smart clock based on an Amlogic A213Y SoC for smart displays and digital signage applications I had never heard of. Let’s have a look at both. UGOOS AC1 smart clock The AC1 smart clock features a 480×480 resolution display, supports Bluetooth pairing, alarms with different ringtones, displays weather, date, time, and sensor data, and supports features such as photo frame, event notes, and music playback.
