Sound Lab is an analogue synthesiser, consisting of six modules that can be combined in a variety of ways. It uses a single printed circuit board that doubles as the front panel and wiring, with surface-mount components and PCB-mounted controls to make the construction as easy as possible:
The Open Compute Project (OCP) Global Summit 2019 kicks off today in San Jose where a vibrant and growing community is sharing the latest in innovation to make hardware more efficient, flexible, and scalable.
These are 80's-era erasable programmable read-only memories, or EPROMs. They were an immensely popular way to store firmware for embedded systems when the
Intel's 386 processor (1985) was an important advance in the x86 architecture, not only moving to a 32-bit processor but also switching to a...
In my previous blog post I talked about how I bought a Blu-ray drive and a couple of M-Discs to use it for long-term archival backups.
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…
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…
That’s VME as in Virtual-8086 Mode Enhancements, introduced in the Intel Pentium Processor, and initially documented in the infamous NDA-only Appendix H.
The soft robotic gripper developed at the U of A received a U.S. patent.
You might think that Apple, Commodore or perhaps Radio Shack made the first personal computer, but you’d be wrong.

The Pixel 8 hardware ( Tensor G3 ) supports the ARM Memory Tagging Extension (MTE) , and software support is available both in Android userspace and the Linux kernel. This feature is a powerful defense against linear buffer overflows and many types of use-after-free flaws. I’m extremely happy to see this hardware…
MIT and Harvard physicists have created a new form of light that could enable quantum computing with photons.
Much of modern Apple’s design philosophy is to relentlessly strip down most products to the bare minimum in certain areas as technological progress allows, following (and largely defining) the modern design fashion of nearly-unquestioned devotion to minimalism.
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.
CU Boulder researchers have developed 3D-printable materials embedded with living bioluminescent algae that can produce sustained light.
This post describes how we repaired the monitor from a Xerox Alto. The Alto was a revolutionary computer, designed in 1973 at Xerox PARC ...
Let's look at this little gizmo Sony produced in the early 1990s.
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…
In 2004 I built the first AppleCrate , an 8-board system, as an inexpensive, easy to program vehicle for experiments in parallel programming�a kind of "blade server" for the Apple II, if you will! AppleCrate I (at the time I didn't realize that it was number "I" ;-) was great fun, and it enabled some very interesting…
There are villages in the Ecuadorian Andes that are so small you cannot find them on a map. Cajas Juridica is one such place, located just 13km north of the equator. But two engineering students, Joshua Salazar and Jorge Vega, and the staff of Yachay Tech University have figured out a way to give discarded….
From OP 2230, "Workmanship and Design Practices for Electronic Equipment" , published by the direction of the chief of the Bureau of Naval Weapons , 1 December, 1962. pp. 7-9 --- 7-14.
EDIT - the original article has an image of the PCB with the floppy power connector mounted the WRONG WAY. This is the INCORRECT WAY. Do NO...
As I was debugging a wireless mouse based on a 2.4 GHz proprietary protocol, I wanted to detect the transmitted signals. Note that I purposefully wrote “detect”: It was sufficient to see how often the transmission occurred (and if at all) and whether the link was unidirectional – i.e., only the mouse transmits and the…
To kick off MARCHintosh, I built this tiny pint-sized Macintosh with a Raspberry Pi Pico: This is not my own doing—I just assembled the parts to run Matt Evans' Pico Micro Mac firmware on a Raspberry Pi Pico (with an RP2040). The version I built outputs to a 640x480 VGA display at 60 Hz, and allows you to plug in a…
To test if a display interface works we often don't want to use a huge framework like GTK or Qt. This article shows an easy way on how we can use a framebuffer directly on a DRM graphics driver under Linux.
