Sniffing PS5 Controller Packets with Cynthion
https://www.youtube-nocookie.com/embed/DHjmOFIk2nk
In our latest training video Martin uses Cynthion to sniff PS5 controller packets. The video guides you through how to set up Cynthion, how to use Packetry, and what PS5 controller packets look like. If you are just getting started with Cynthion or learning about USB, we suggest checking out this video.
Free Stuff - March 2024
The belated March 2024 Free Stuff recipient for the Great Scott Gadgets Free Stuff Program is Benjamin Pieres! Benjamin is a newly licensed amateur radio operator who is excited to contribute to the amateur radio community and share his passion for radio communication through workshops and innovative experiments.
One of the workshops Benjamin envisions hosting is focused on introducing basic radio communication principles to beginners. Participants will learn about radio wave propagation, antenna design, and the fundamentals of operating amateur radio equipment. Additionally, Benjamin plans to organize workshops on emergency communication preparedness, where attendees will learn how to establish communication networks...
A surprising IC in a LED light chain.
LED-based festive decorations are a fascinating subject for exploration of ingenuity in low-cost electronics. New products appear every year and often very surprising technology approaches are used to achieve some differentiation while adding minimal cost.
This year, there wasn’t any fancy new controller, but I was surprised how much the cost of simple light strings was reduced. The LED string above includes a small box with batteries and came in a set of ten for less than $2 shipped, so <$0.20 each. While I may have benefitted from promotional pricing, it is also clear that quite some work went into making...
Пасхалка в Eagle
Eagle (если вдруг кто не знает), это CAD для проектирования печатных плат, разработанный компанией CadSoft Computer GmbH, и впоследствии перекупленный и убитый компанией Autodesk.
Исследуя внутренности исполняемого файла Eagle под MacOSX, обнаружил, что даннае программа должна содержать в себе "пасхалку", запускаемую из редактора печатных плат. Какой-то информации на эту тему не удалось обнаружить в интернетах. Однако, всё оказалось очень просто - достаточно ввести команду "snake" в командной строке (что находится в верхней части окна), причём, делать это надо именно в редакторе плат, и вуаля.
Видим игровое поле, постоенное из контуров печатной платы. После...
Antenna diodes in the Pentium processor
I was studying the silicon die of the Pentium processor and noticed some puzzling structures where signal lines were connected to the silicon substrate for no apparent reason. Two examples are in the photo below, where the metal wiring (orange) connects to small square regions of doped silicon (gray), isolated from the rest of the circuitry. I did some investigation and learned that these structures are "antenna diodes," special diodes that protect the circuitry from damage during manufacturing. In this blog post, I discuss the construction of the Pentium and explain how these antenna diodes work.
Closeup of the Pentium die showing the silicon and bottom...
Электровакуумная химия в домашней мастерской. Очистка, обезжиривание металлов
Электровакуумные приборы (ЭВП) часто имеют немудрёное устройство и конструкцию, повторить которые нетрудно и относительно простыми средствами. Однако характеристики таких приборов и их стабильность, а прежде всего долговечность ламп, в целом остаётся весьма низкой. Сложности изготовления практических образцов ЭВП — это миниатюрность и точность, подбор и герметическое соединение необычных и разнородных материалов для широкого диапазона рабочих температур, где их чистота должна превосходить хирургическую — самые малые субмикроскопические внутри баллонные загрязнения оборачиваются нежелательными физико-химическими процессами во время работы лампы, сокращают срок её службы или вовсе выводят из строя. Причём в условиях значительных рабочих температур и высокого вакуума, нежелательные пары и газы...
November Update: Something Borrowed Something New

Hacking Wowme U300Q Car Camera to Actually Work
I recently came across a Wowme U300Q car camera on an auction at aukro.cz . At first glance, it seemed like a promising piece of tech, but after trying to use it, I quickly realized there was a major flaw—it didn’t rotate recorded files and it was not just an issue with my piece, also reviews confirmed it as a global problem. For anyone familiar with dash cams, this is a critical issue because, without rotating files, the camera quickly runs out of storage and stops recording.
The Initial Problem: A Broken CameraWhen I first set up the Wowme U300Q, I...
