When we launched Raspberry Pi Zero last November, it’s fair to say we were blindsided by the level of demand. We immediately sold every copy of MagPi issue 40 and every Zero in stock at our distributors; and every time a new batch of Zeros came through from the factory they’d sell out in minutes. To […]
When Intel released the 80386 in October 1985, it marked a watershed moment for personal computing. The 386 was the first 32-bit x86 processor, increasing the register width from 16 to 32 bits and vastly expanding the address space compared to its predecessors. This wasn't just an incremental upgrade—it was the…
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…
A magazine on a floppy from 1986.
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.
A very warm welcome to my most ambitious project to date. In this project I’m going to attempt to design and build a sprite-based graphics accelerator that will function as a co-processor to an MCU. Using cheap off-the-shelf components I’m hoping to achieve a level of gaming performance that compares well to popular…
The GDP was exclusively object oriented - normal linear memory access wasn't allowed, and there was hardware support for data hiding, methods, inheritance, late binding, and access protection, and it was promoted as being ideal for the Ada programming language. To enforce this, permission and type checks for every…
A few months ago, I decided that it’s time I started to become more responsible and to start drinking more water. Unfortunately, the tap water where I live has a very high calcium content, which makes it a lot better when filtered and cooled first. To solve both issues, I picked up a second-hand professional water…
While everyone was waiting on news for the successor of the Nintendo Switch, Nintendo released the Alarmo. A small plastic alarm clock that ...
Note: this is the first part of three articles about my experience building a 1980s Yugoslav 8-bit computer called the Galaksija. This part is mostly focused on the technical aspects of building this…
Welp, it is real. These images are straight out of System/Library/PrivateFrameworks/PassKitUI.framework/Versions/A/Resources on my Mac running 10.12.1: There’s a lot to parse here. Clearly, the rumors of a Magic Toolbar are all correct, as well the inclusion of Touch ID to the right of the Toolbar. It looks like…
In 1979, Intel introduced the 8088 microprocessor, a variant of the 16-bit 8086 processor. IBM's decision to use the 8088 processor in the I...
Pixel Watch 3, the latest version of our flagship smartwatch, offers a stunning design combined with even better performance.
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…
I finally upgraded to a mechanical keyboard. But because Apple's so protective of their Touch ID hardware, there aren't any mechanical keyboards with that feature built in. But there is a way to hack it. It's incredibly wasteful, and takes a bit more patience than I think most people have, but you basically take an…
Being involved with retro computers, I have a few floppy disks (of the 3.5-inch variety) that I would like to preserve as faithfully as possible. Of course, I know there are dedicated devices for doing that, such as the Kryoflux or the SuperCard Pro . But it occurred to me that I already own the required hardware to…
The problem with enforcing TPMs on consumers
Fast compact external SSDs are prone to thermal throttling. This is demonstrated during tests writing 96 files, when transfer rates fell from 2 GB/s to around 700 MB/s.
Explorers planning to settle on Mars might be able to turn the planet’s red soil into bricks without needing to use an oven or additional ingredients. Instead, they would just need to apply pressure to compact the soil—the equivalent of a blow from a hammer. These are the findings of a study published in Nature…
I'm going to neuralyze the SPI flash and install some Kelvin Timeline firmware that will allow me to boot and install generic ARM Linux images on a ROCK 5 ITX+.

How to connect a 68k Mac to the internet without an ethernet card!
Having 32 (31) registers, this means that a refresh will be issued each 256us. To be on the safe side, the capacitor should keep its charge much longer than that. Testing with both EAA91 (ideal diode) and some semiconductors: Diode charge hold time Comment EAA91 >500us ideal diode 1N4148 >500us for reference, leakage…
