Don't pay $800 for Apple's 2TB SSD upgrade

Apple charges $800 to upgrade from the base model M4 Mac mini's 256 GB of internal storage to a more capacious 2 TB.

Pictured above is a photo of a standard 2230-size M.2 NVMe SSD (one made by Raspberry Pi, in this case), and Apple's proprietary not-M.2 drive, which has NAND flash chips on it, but no NVM Express controller, the 'brains' in a little chip that lets NVMe SSDs work universally across any computer with a standard M.2 PCIe slot.

CaribouLite SDR HAT for SDR on a Raspberry Pi

CaribouLite SDR HAT for SDR on a Raspberry Pi

A couple years ago, after I heard about the CaribouLite on CrowdSupply, I pre-ordered one.

I've dabbled in SDR with an RTL-SDR v3 for a few years, even using one with nrsc5 to listen to baseball games OTA because of silly MLB blackout restrictions.

But low-cost SDRs like the RTL-SDR v3 are receive-only, and have a limited frequency range, and lower quality RF filtering, so it can be frustrating if you're trying to work with lower-power RF... or trying to transmit at...

Простая муфельная эрзац-электропечь из недорогих подножных материалов

Работа со стеклом вообще и электровакуумное производство в частности, широко используют печной нагрев, причём в последнем случае это может быть целый ряд специализированных технологических аппаратов — от несложных подогреваемых кожухов на откачных постах или автоматах, до печей вакуумных и водородных для подготовки материалов. Ниже описана сборка очень простой импровизированной муфельной печи для электровакуумных экспериментов в домашней мастерской. Основное назначение прибора — отжиг сложных самодельных ЭВП (электровакуумных приборов) и их частей, нагрев при откачке и наполнении ЭВП, в том числе и при изготовлении оксидных катодов.

Cyfral Intel. Перепрошиваем «говорящий» домофон

Приветствую всех!
Давным-давно, когда ещё не перевелись оптические и магнитные ключи, некоторые компании разрабатывали домофоны с какими-то дополнительными функциями: охранная сигнализация, диспетчеризация, релейные входы или выходы и тому подобные возможности. Можно сказать, что это прямой предок нынешних «умных» домофонов.
У меня давно уже лежал такой девайс, и я всё думал, что бы такого интересного про него рассказать. И вот, увидев пост товарища zatim про звонок (и немало им вдохновившись), я вдруг догадался: да это же почти что более навороченный преемник того самого девайса! А раз так, то как насчёт препарировать и его?
Итак, в сегодняшней статье поговорим про устройство и работу таких домофонов,...

Liminal Ring – (Un)controllable currents in the persistence of chaos

Get full content RSS Feed

Liminal Ring visualizes humanity's obsession with controlling nature while exposing the limitations of such interventions. By introducing laminar flows—artificially directed streams—into naturally occurring turbulence, this project explores the boundary between certainty and uncertainty. It highlights the tension between the order imposed by human technology and the chaotic complexity inherent in natural systems.

PXL DEX is a series of fully on-chain real time animations created by Kim Asendorf where each pixel is a token in itself. PXL DEX is the first artwork within the PXL ecosystem, an ongoing work series to experiment with pixels as utility tokens. The collection consists of 256 NFTs that are deployed via a custom Smart Contract on the Ethereum Mainnet.

Interesting BiCMOS circuits in the Pentium, reverse-engineered

Intel released the powerful Pentium processor in 1993, establishing a long-running brand of processors. Earlier, I wrote about the ROM in the Pentium's floating point unit that holds constants such as π. In this post, I'll look at some interesting circuits associated with this ROM. In particular, the circuitry is implemented in BiCMOS, a process that combines bipolar transistors with standard CMOS logic.

The photo below shows the Pentium's thumbnail-sized silicon die under a microscope. I've labeled the main functional blocks; the floating point unit is in the lower right with the constant ROM highlighted at the bottom. The various parts of the floating point unit form horizontal stripes. Data...
