Naya Connect modular mechanical keyboard offers trackball, touchpad, rotary encoder, and spacial controller options (Crowdfunding)

Dutch hardware startup Naya Create has launched the Naya Connect, a modular mechanical keyboard featuring magnetic connectors for additional keypads, and a dock to add a trackball, a multitouch touchpad, a rotary encoder, or a spatial controller. It is designed for 3D artists, video editors, audio professionals, and CAD engineers, as well as finance and business users. The core system, or the brain of the product, is the Naya Type, an 85-key mechanical keyboard in a 75% form factor with a 14.9 mm CNC aluminum unibody. It uses Kailh Choc V2 low-profile mechanical switches mounted on hot-swappable sockets and paired...

Ode to the AA Battery

Recently this post from @Merocle caught my eye:

I'm fixing my iFixit soldering station. I haven't used it for a long time and the battery has gone overdischarge. I hope it will come back to life. Unfortunately, there are no replacements available for sale at the moment.

Devices with built-in rechargeable batteries have been bugging me a lot lately. It's convenient to have a device you can take with you and use anywhere. And with modern Li-ion cells, battery life is remarkable.

Streaming a Turntable or CD to AirPlay Speakers

This article explains how to stream audio from a turntable or CD player to AirPlay and AirPlay 2 speakers using a Raspberry Pi. Hi-Fi was simple; a literal one-step process. …

Sipeed MaixCAM2 combines 4K imaging and edge AI in an open camera platform

The device is designed as an open system for rapid deployment of vision, audio, and AIoT applications, aimed at researchers, and developers requiring more capable on-device inference and improved image quality than typical DIY camera setups. MaixCAM2 is built around an Axera AX630-series SoC with dual Arm Cortex-A53 cores running Linux, paired with a small […]

Recapping My 5 Year Old Studio Monitors

A few weeks ago, I started hearing a slight crackle at the loudest parts of whenever sound was playing through my PreSonus Eris E3.5 speakers. It was very faint, but quite annoying, especially when editing my YouTube videos.

For a few days I thought it could be a hearing problem (at this point in my life, every year brings a new health adventure...), but after testing my wired headphones and another small computer speaker on the same output, I determined the problem was, indeed, coming from the PreSonus speakers.

Notes on the Intel 8086 processor's arithmetic-logic unit

In 1978, Intel introduced the 8086 processor, a revolutionary chip that led to the modern x86 architecture. Unlike modern 64-bit processors, however, the 8086 is a 16-bit chip. Its arithmetic/logic unit (ALU) operates on 16-bit values, performing arithmetic operations such as addition and subtraction, as well as logic operations including bitwise AND, OR, and XOR. The 8086's ALU is a complicated part of the chip, performing 28 operations in total.1

In this post, I discuss the circuitry that controls the ALU, generating the appropriate control signals for a particular operation. The process is more complicated than you might expect. First, a machine code instruction results in the...

Стеклодувные горелки. От истоков к современности. Краткий экскурс

Несмотря на архаичность ручной формовки стекла, стеклодувное дело ещё отчасти живо и привлекает своих адептов, в том числе и как хобби, домашние любительские экзерсисы. Сегодня ремесло это довольно громоздкое и дорогостоящее, так, однако, было не всегда — взять хотя бы горелки — первое, о чём задумывается будущий стеклодув. Рассмотрим же, с помощью чего творили предки и как развивалось огневое оснащение стеклодувного дела со времён царя Гороха, до дней нынешних, взглянем заодно на интересные примеры и вообще, полюбуемся огнями. За мной, мои дорогие пироманы, за мной!

Выход в интернет с ПК на i486DX4 в 2026 году

Приветствую всех!

Думаю, всем нам известно: ещё каких-то лет десять назад "компьютером для интернета" назывался очень бюджетный офисный ПК, тогда как теперь потребление ресурсов возросло настолько, что порой современный веб - чуть ли единственное, с чем не справляется тот или иной девайс.

А как насчёт чего-то совсем старого? Можно ли выйти в сеть с компьютера тридцатилетней давности и остались ли ещё какие-то сайты, которые можно полноценно просматривать с такого ПК? Сейчас и узнаем...
