Testing the Raspberry Pi 500+'s new mechanical keyboard

Testing the Raspberry Pi 500+'s new mechanical keyboard

Instead of a traditional review of a new Pi product, I thought I'd split things up on my blog, and write two separate posts; this one about the Pi 500+'s new mechanical keyboard, and a separate post about hacking in an eGPU on the Pi 500+, for a massive uplift in gaming performance and local LLMs.

The Raspberry Pi 500+ was announced today, sells for $200, and adds on the following over what was present in the regular Pi 500:

5 Ways Embedded AI Processors are Revolutionizing Device Performance (Sponsored)

Artificial intelligence (AI) is moving from cloud-first architectures to edge-first designs, so more processing now runs on phones, cameras, and embedded controllers. Running inference on-device cuts latency and keeps sensitive data local. This momentum is reshaping product roadmaps, all due to different revolutions driven by edge AI. The Core Revolutions Driven by Edge AI Instead of routing every model and signal to the cloud, devices are processing more data locally to act faster and protect sensitive information. Because edge AI is changing where intelligence runs, IDC estimates global spending on edge computing reached about $261 billion in 2025. This rapid...

BIOSTAR MU-N150 – A Twin Lake fanless Industrial PC with 2.5GbE, triple 4K video output

BIOSTAR has launched the EdgeComp MU-N150, a compact 0.6L fanless industrial PC built around the Intel Processor N150 ” Twin Lake” SoC for edge computing, automation, HMI, POS/kiosk, and more. Some other N150 systems, like the HUNSN RJ42/RJ43 and Protectli VP2430, are for networking with four 2.5GbE ports, while the MU-N150 uses dual LAN but adds industrial-grade durability. The PC supports up to 16GB DDR5 4800MHz memory, triple 4K video output, and dual 2.5GbE. Expansion option includes M.2 Key-M slot for NVMe storage and an M.2 Key-E slot for Wi-Fi/BT modules. Other features include 2x USB 3.2, 2x USB 2.0,...

Particle Tachyon Review – A Qualcomm QCM6490 Edge AI and 5G cellular SBC tested with Ubuntu

Hello, today I’m going to review the Particle Tachyon SBC designed for high-performance edge AI, IoT, and connectivity applications. Powered by the Qualcomm QCM6490 platform with an octa-core Kryo CPU, an Adreno GPU, and a Hexagon DSP. The board also integrates robust wireless options, including 5G, Wi-Fi 6E, and Bluetooth 5.2. The Particle Tachyon adopts the Raspberry Pi form factor and provides various I/O interfaces, such as a 40-pin GPIO header compatible with Raspberry Pi HATs, along with expansion options for sensors and peripherals. It also includes a Qwiic connector for SparkFun and Adafruit integrations, as well as MIPI-CSI/DSI connectors...

Microchip PIC programmers in stock

MPLAB-PICKIT3 is low cost entry level programmer/debugger for PIC microcontrollers which do not need introduction as it’s quite mature solution. PICKIT3 have one notorious bug when it powers the target in MPLAB you can select any voltage up to 5V but as it have protection diode where 0.6V is dropping it can’t provide more than […]

You can finally manage Macs with FileVault remotely in Tahoe

You can finally manage Macs with FileVault remotely in Tahoe

For years, I've had a couple Macs running at home and at my studio, which I use to remotely manage my video projects or some coding project.

It's nice to have a workstation set up that you can access anywhere via Screen Sharing to check on progress, jot down a note, etc.—and not be tied to a web app or some cloud service.

I run a Wireguard VPN at home and at my studio, so I can remotely log into any...

I regret building this $3000 Pi AI cluster

I regret building this $3000 Pi AI cluster

I ordered a set of 10 Compute Blades in April 2023 (two years ago), and they just arrived a few weeks ago. In that time Raspberry Pi upgraded the CM4 to a CM5, so I ordered a set of 10 16GB CM5 Lite modules for my blade cluster. That should give me 160 GB of total RAM to play with.

This was the biggest Pi cluster I've built, and it set me back around $3,000, shipping included:

Приём служебного GSM-трафика без использования SDR

Приветствую всех!

Интересующиеся сотовыми сетями наверняка слышали про то, что сигнальные сообщения, передающиеся открытым текстом, можно принять на самый обычный ТВ-тюнер на чипе от Realtek. Для более продвинутых пользователей существует прошивка Osmocom, софт Airprobe и более продвинутые модели SDR. Но как насчёт анализа вообще без использования SDR и тому подобных устройств?

Не так давно появился инструмент, позволяющий ещё больше снизить порог вхождения для таких опытов. Именно о нём мы сейчас и поговорим.
