Recent studies have suggested various side-channel attacks for eavesdropping sound by analyzing the side effects of sound waves on nearby objects (e.g., a bag of chips and window) and devices (e.g., motion sensors). These methods pose a great threat to privacy, however they are limited in one of the
In my last post, I showed you to use FireWire on a Raspberry Pi with a PCI Express IEEE 1394 adapter. Now I'll show you how I'm using a new FireWire HAT and a PiSugar3 Plus battery to make a portable MRU, or 'Memory Recording Unit', to replace tape in older FireWire/i.Link/DV cameras. The alternative is an old used…
I have been meaning for a while to establish a setup to implement neural network based algorithms on smaller microcontrollers. After reviewing existing solutions, I felt there is no solution that I…
A few months ago I introduced you to one of the more notable Apple pre-production units in my collection, a late prototype Macintosh Porta...
Nowadays, there is increasing interest in adding tagged memory functionality to CPU architectures. Such architectures associate one or more tag bits with each quantum of a system's memory. There are many motivations for this ability to associate “metadata” with individual memory words, but one of the most clear is the…

Chris Herridge spent eleven months painstakingly rebuilding the engine of his Triumph Spitfire Mk3 , and photographing the process. Over 3,000 photos later, and he created this amazing video of an engine being disassembled and rebuilt.
Linux kernel experiments implementing IB verbs over consumer Thunderbolt/USB4 hardware to give cheap mini-PCs high-performance RDMA suitable for cluster inference.
Rockwell famously used 6502-based cores in modems for many years, but that doesn't mean other 6502s couldn't be used. If only there were a w...
A couple of months ago I stumbled upon a post on Hackaday about an inexpensive open-source USB 2.0 sniffer created by Alex Taradov . This is a really cool project! Normally, USB sniffers like this can cost thousands of dollars, especially if you’re paying for fancy protocol decoding and also want high-speed 480 Mbps…
Long-time readers will know that my first video game love was the text-mode video game slash creation studio ZZT. One feature of this game is the ability to ...
DPReview just published Apple still hasn't made a truly “Pro” M1 Mac – so what’s the holdup? Following on the good performance and awesome power efficiency of the Apple M1 , there’s a hungry background rumble in Mac-land along the lines of “Since the M1 is an entry-level chip, the next CPU is gonna blow everyone’s…
Last year I started collecting ideas of things I would like to 3D print one day, on Twitter. Twitter is fundamentally ephemeral, so I'll collect it here instead. I got up to 14 items on Twitter, and now I'm up to 25.
SANTA CLARA, Calif.--(BUSINESS WIRE)-- Intel Corporation today reported second-quarter 2024 financial results.
So you decided to build a brand new system using all the latest and coolest tech, so you buy a Ryzen 7000 series Zen 4 CPU, like the Ryzen 7700X that I picked, with a new mother board and DDR5 memory
Disclaimer: this, by no means, is not a definitive description of the whole embedded-specific development. This is just a small good practice about interaction with hardware.
This blog post shows how to create a reliable and realistic-looking malicious USB key that can be used in a drop attack.
We traded the physical boundaries of dedicated rooms for the convenience of our always-on digital lives -- but recently I've been building those walls back up.
Today Raspberry Pi Trading announced the Raspberry Pi 400, the latest in the series of small education-focused computers that started with the original Raspberry Pi in 2012. For years, people have come up with creative ways to hack a Pi into keyboards, like the Original Pi in an old Mitsumi keyboard, or the Pi 3 A+ in…
We’re pleased to announce several updates to Google Compute Engine that give you more powerful and flexible instances. Google Cloud is the first and only public cloud to deliver Intel’s next-generation Xeon server processor (codenamed Skylake), and starting today, it’s generally available (GA). In addition, we’ve made…
Last month, the 100,000th hardware engineer registered on SnapEDA, so I thought it would be fun to reach out to learn more about what they were working on. Little did I know that it would turn out to be so epic!
