ARLINGTON, Va., USA – MARCH 5, 2024 – JEDEC Solid State Technology Association , the global leader in the development of standards for the microelectronics industry, is pleased to announce the publication of JESD239 Graphics Double Data Rate (GDDR7) SGRAM. This groundbreaking new memory standard is available for free…
You can upgrade the storage in your Raspberry Pi 4 with an NVMe drive using USB3 to get more reliable storage and faster I/O than an SD…
These extensions expand the x86 instruction set with access to registers and features that improve performance.
I recently wrote a post to announce the availability of M6g, R6g and C6g families of instances on Amazon Elastic Compute Cloud (Amazon EC2). These instances offer better cost-performance ratio than their x86 counterparts. They are based on AWS-designed AWS Graviton2 processors, utilizing 64-bit Arm Neoverse N1 cores…
It's one of my periodic downsizing cycles, which means checking the hardware inventory (and, intermittently, discovering things that were no...
Last week Joe Chilcote discovered an interesting message when imaging a Late 2016 MacBook Pro TouchBar (from here on out referred to as TBP): A critical software update is required for your Mac. To…
Why monitors priced from hundreds to thousands of dollars often use the same low-cost PM modules, and what that means for performance claims.
A little over a month ago, I ran into a Tektronix TDS7104 at the Silicon Valley Flea Market , where else?
So some innocent post on the coreboot mailing list managed to make some waves. The problem Intel tries to solve… Intel Boot Guard is the latest effort in a long series by Intel and others to allow computers to provide some reliable information about the state a computer is in. They’re working on it since at least…
A few weeks ago, I received two early copies of Uptime.Lab's CM4 Blade. The Blade is built for the Raspberry Pi Compute Module 4, which has the same processor as the Pi 4 and Pi 400, but without any of the built-in IO ports. You plug the CM4 into the Blade, then the Blade breaks out the connections to add some…
The RGB curtain predictably turns into a mess of wires when not used according to instructions. As should be obvious from this blog, I am somewhat drawn to clever and minimalistic implementations o…
It is possible to monitor and control float trucks, public bus or delivery vans from the internet , obtaining their speed, position, and a lot other parameters. You can even control some parameters of the vehicle or hack into the canbus of the vehicle remotely.
If you look for information about the Macintosh Plus and its ROM, you’ll usually find that the ROM has a capacity of 128 KB and that it exists in three revisions . But that’s incorrect: there’s a fourth ROM, 256 KB in size, which includes fonts for kanji (Japanese characters). And I found (and preserved) this ROM. I’m…
Here's how I built an ultrasonic 3d scanner that works in the air, using off-the-shelf components.
We’re tearing down the evolution of Nintendo controllers since the very beginning.
TDOA Sound Localization is determining the source of a sound when all you know is the differences in the time of arrival of the sound event…
A fast, low-latency, open hardware e-ink monitor and dev kit
In this post series I will explain the making of a radio-controlled submarine. I will go through the design, the building process, Python code, tests in water, and all the mistakes I made. Lots of …
In my day job I work with ion thrusters for spacecraft, which are essentially electric-powered rockets that fling Xenon gas out at super high speeds to provide thrust and allow satellites to change…
In recent years, compute-intensive artificial intelligence tasks have prompted creation of a wide variety of custom hardware to run these powerful new systems efficiently. Deep learning models, suc…
Modified curve tracer is applying AC voltage. Horizontal axis represents voltage and the vertical axis represents current. In both cases, the curve always passes through zero voltage and current. This requirement must be met in order to be classified as a memristor.
Since releasing 486Tang , I’ve been working on recreating the 8086 with a design that stays as faithful as possible to the original chip. That exploration naturally led me deep into the original 8086 microcode — extracted and disassembled by Andrew Jenner in 2020.
iPhone 15 Pro and iPhone 15 Pro Max users can now capture spatial videos, which they can relive on Apple Vision Pro starting early next year.
I'm working on a project—a very dumb project, mind you—and I was trying to acquire the two current-gen flagship GPUs: an Nvidia RTX 4090, and an AMD Radeon RX 7900 XTX. In some weird stroke of luck (it has been difficult to find either in stock), I was able to get one of each this week. (lol at the size difference...)
