During a recent RAID 5 recovery attempt, John made an interesting discovery inside the two failed disks. The plastic ramp that the heads park onto when idle had snapped in the same position on both drives. We don’t know if the heads got damaged first, and then broke the ramps during parking, or if the […]
Since the Compute Module 4 came along last year, there have been a few projects that use it that make me do a double-take: They did what with a Pi? Alftel's Seaberry is a carrier board for the CM4 in the Mini ITX form factor that adds on eleven PCI Express slots: 1 x16 slot (with x1 lane) in the standard ITX location…
We've barely scratched the surface of the Pi Zero 2's capabilities. [Brian Dorey] shows us how to hack your Pi's WiFi and improve its performance. A u.FL footprint can be discovered in line with the onboard WiFi antenna, implying that someone had to connect an external antenna.
Introduction This article is part 3 on EyeWay Vision’s (EyeWay) foveated laser scanning display and follows up on Part 1 that discussed the technology, and Part 2 that showed through-the-opti…
I have just released a serial port based Amiga disk and file transfer tool, amigaXfer .
We do not see many vintage Japanese workstations in the West. We also do not see many portable workstations (of any make). So, what we really rarely see, are Japanese portable workstations. I feel …
When it comes to electronics, I am a woman of simple interests. Ideally, I only want to care about one voltage, and ground– there’s a reason I did so much be...
Networking and communication is something that has been on our minds as of late. As many of you are surely aware, we have started developing our own solution to private and secure peer-to-peer and group text messaging based on the PineDio gateway system, available next month. While we have high hopes for this system…
This article covers several repairs, one including reverse engineering the BIOS to allow replacement parts. Feel free to scroll down and skip to this content.
Toyota Motor Corporation (Toyota) has developed a product that packages a fuel cell (FC) system into a compact module and plans to begin selling it in the spring of 2021 or later. The new module will be easily utilized by companies that are developing and manufacturing FC products for wide variety of applications…
How do you boot a computer from punch cards when the computer has no operating system and no ROM? To make things worse, this computer req...
Just recently, there was a surge in traffic to my old legacy dial-up sounds pages. While I did my best with the equipment I had at the time to capture the sound of dial-up modems, I always knew tha…
Electronics and plastic casing parts of Flipper Zero are manufactured at different factories. Today we will visit the electronics factory and take a look at the automatic PCB testing. There is always a non-zero defect rate when it comes to high-volume production. Some produced PCBs might turn out faulty, some
Since the Raspberry Pi was introduced, hundreds of clones have adopted the Pi's form factor (from the diminutive Zero to the 'full size' model B). Often they have better hardware specs, and yet they remain a more obscure also-ran in that generation of Single Board Computer (SBC). So when I saw Radxa's CM3 and Pine64's…
Japan's greatest inventor whose life span a formative period in the nation's history, Tanaka Hisashige built the Myriad Year Clock, a 1000-part masterpiece that's today a national treasure.

TL;DR : we reproduced Denis Andzakovic’s proof-of-concept showing that it is possible to read and write data from a BitLocker-protected device (for instance, a stolen laptop) by sniffing the TPM key from the LCP bus.
I recently received a vintage IBM paperweight from the early 1970s that showcases some memory chips. 1 When IBM started using integrated ...

A couple of weeks ago I found a really good deal on a Socket AM4 motherboard that supports the newest AMD Ryzen CPUs. The motherboard is an ASRock A520M/ac . It’s a very basic motherboard which doesn’t appear to be sold by any of the usual retailers anymore, but I couldn’t pass up on the deal, especially with the…

The ramblings and experiments of a software engineer and tech enthusiast based in Dublin.
Thirty years after its launch in 1987, a CM-2 was acquired by MoMA NY. It is only on display in selected shows - its inaugural exhibit was in " Thinking Machines: Art and Design in the Computer Age, 1959-1989"
We're launching a new website dedicated to Raspberry Pi computers, and new social media channels focused on our educational initiatives.
The conventional view of Software Testing The hardware and software worlds may seem poles apart, and in many ways, they indeed are. But there’s a wealth of knowledge that each can learn from the ot…
Building a tiny FORTH for an Arduino UNO in one week
The other day I asked myself a seemingly trivial question: What was the first ATAPI CD-ROM drive and when was it available? Given that ATAPI was a major technology which instantly obsoleted all proprietary CD-ROM interfaces and made SCSI much less desirable, one might expect that there would have been some press…
