Eazeye Radiant 15.6-inch portable transflective LCD review

Eazeye sent me a sample of the Radiant 15.6-inch transflective LCD review for review after I wrote about the Eazeye 2.0 24-inch reflective LCD monitor last August. Yes, there’s been a little bit of miscommunication as I got a transflective LCD (TLCD) launched last year, instead of the new reflective LCD (RLCD). But that’s OK. While those are two different technologies, both monitors are designed to rely on natural light, and I assumed either would perform better outdoors and reduce eye strain compared to traditional portable monitors or laptop displays. Let’s find out. Eazeye Radiant unboxing and specifications I received...

FireBeetle 2 ESP32-C5 IoT development board offers GDI display interface, LiPo battery support

Just the other day, I lamented the lack of options when it came to ESP32-C5 boards featuring dual-band WiFi 6 support. The FireBeetle 2 ESP32-C5 IoT development board made by DFRobot shows that I needed to be more patient… The ESP32-C5 board features 4MB flash, a USB-C port, a LiPo battery connector, and two GPIO headers for expansion, as well as a GDI display connector designed to add an SPI/I2C touchscreen display. The new RISC-V board has about the same features and form factor as the FireBeetle 2 ESP32-S3. It adds 5 GHz WiFi and an 802.15.4 radio for Zigbee,...

Using AMD GPUs on Raspberry Pi without recompiling Linux

Using AMD GPUs on Raspberry Pi without recompiling Linux

I'm working on a more in-depth test of some newer AMD GPUs on the Raspberry Pi, now that the 15 line kernel patch is (IMO) nearly ready for upstreaming.

But this blog post shows how to quickly get almost any modern AMD GPU running on a Raspberry Pi 5, CM5, or Pi 500+, thanks to this patch on the Pi Linux fork.

Turris Omnia NG Wi-Fi 7 router features dual 10GbE SFP+, mini PCIe slot for 4G LTE/5G, runs OpenWrt-based Turris OS

The Turris Omnia NG is a high-performance Wi-Fi 7 router with a mini PCIe slot for 4G/5G modems, two 10GbE SFP+ cages, a 240×240 px color display, and a D-Pad button, running OpenWrt-based Turris OS, and designed for advanced home users, small businesses, and lab environments. Built around a 2.2 GHz Qualcomm IPQ9574 quad-core 64-bit Arm Cortex-A73 CPU, the Omnia NG supports Wi-Fi 7/6 tri-band connectivity. Additionally, it features four 2.5Gbps Ethernet ports, two USB 3.0 ports, NVMe storage support, and includes a 90 W power supply for attached peripherals. Other hardware highlights include rack-mount supports, a metal chassis, and...

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:
