Die photo of the Intel Pentium processor with the floating point constant ROM highlighted in red. (Credit: Ken Shirriff) Released in 1993, Intel’s Pentium processor was a marvel of technological progress. Its floating point unit (FPU) was a big improvement over its predecessors that still used the venerable CORDIC algorithm. In a recent blog post […]
According to [ClassicHasClass], the best way to open an Atari Stacy is to not open an Atari Stacy. Apparently, these old computers were not pleasant to work on. The cables were not keyed and were prone to short against things. Screws easily strip out plastic holes. Of course, there wouldn’t be a story if there […]
For better or worse, Atari is no longer a household name in computing, but for a time in the 1980s, it was a huge mover in the industry. They not only produced PCs but also a huge number of video game consoles. Although they were a major contributor to the video game crash of the […]
We see many 16-bit retrocomputers around here based on Intel and Intel-like chips such as the 8086, 8088, V20, and similar. While they don’t seem very powerful by today’s standards, they were perfectly capable machines and, thanks to Elks (Embeddedable Linux Kernel Subset), you can run something fairly Linux-like on these devices. The requirements are […]
For economic reasons, not every lake with a dam can support a hydroelectric power plant. Some rivers or creeks are dammed for flood control or simply for recreation, and don’t have the flow rate or aren’t deep enough to make the investment of a grid-scale generation facility worthwhile. But for those of us with a […]
Hackerspaces are no strangers to repurposing outdated tech, and Nottingham Hackspace happens to own one of those oddities one rarely gets their hands on: a railway departure board. Left idle for over a decade, it was brought back to life by [asjackson]. Originally salvaged around 2012, it remained unused until mid-2024, when [asjackson] decided to […]
In a stunning example of the Bader Meinhoff effect, we’ve recently heard several times this week about events like the “carbage run.” That is, a motoring event where you can only buy some garbage car to compete. In the case of [Robbe Derks], the idea was to take a six-day journey to the polar circle […]
Have you ever thought of giving new buzz to outdated wired alarm systems or saving money while upgrading your home security? The Hornet Nest Alarm Panel, to which hacker [Patrick van Oosterwijck] contributes, does just that. Designed for domotics enthusiasts, it offers 42 sensor zones and seamless integration with Home Assistant and ESPHome. This open-source […]
Fresh from AliExpress, [Big Clive] got another fascinating item to tear down: a crane claw, as used in those all too familiar carnival games. These games feature a claw the player moves into position above a pile of toys or other items. Lower the claw gently down in the hopes that it grabs the target […]
