«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.

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 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 […]

The module targets embedded applications in machine vision, autonomous robotics, and industrial automation, offering onboard AI acceleration and GPU capabilities optimized for real-time processing and advanced imaging. The TIA RZ/V2H module integrates a Renesas RZ/V2H […]

Minisforum stuffs an entire Arm Homelab in the MS-R1

Minisforum stuffs an entire Arm Homelab in the MS-R1

The Minisforum MS-R1 uses the same Cix CD8180 Arm SoC as the Orion O6 I reviewed earlier this year. But everything else about this thing is different.

What this thing should be, is a box that runs Linux and can compete with at least an Apple M1 Mac mini, or a mid-range Mini PC. But what we got... is something different.

Hate reading? I also published a video on the MS-R1 on my YouTube channel. Watch it here, or scroll on past.
