As computer hardware gets better and better, most of the benefits are readily apparent to users. Faster processors, less power consumption, and lower cost are the general themes here. But sometimes increased performance comes with some unusual downsides. A research group at the University of California, Irvine found that high-performance mice have such good resolution […]
There’s no rule that says that logic circuits must always use electrically conductive materials, which is why you can use water, air or even purely mechanical means to implement logic circuits. When it comes to [soiboi soft]’s squishy robots, it thus makes sense to turn the typical semiconductor control circuitry into an air-powered version as […]
This week Jonathan talks to James Cole about Firefly III, the personal finance manager!

In the history of entertainment, few properties have made the sort of indelible mark on popular culture as Star Trek has. In 950 episodes across the twelve television series that have carried the name, the franchise has made a spectacle not of explosions and machismo, but of competent professionals working together to solve complex problems. […]
Every now and then in histories of the 20th’s century’s earlier years, you will see pictures of cars and commercial vehicles equipped with bulky drums, contraptions to make their fuel from waste wood. These are portable gas generators known as gasifiers, and to show how they work there’s [Greenhill Forge] with a build video. A […]
If there ever was a toy that enjoys universal appeal and recognition, the humble Rubik’s Cube definitely is on the list. Invented in 1974 by sculptor and professor of architecture Ernő Rubik with originally the name of Magic Cube, it features a three-by-three grid of colored surfaces and an internal mechanism which allows for each of […]
We were recently tipped off to quite a resource — on the Texas Instruments website, there’s a page where you can view and download a compendium of analog sub-circuits. Individual circuits can be downloaded in the form of PDF files. If you chose to register (which is free), you’ll also gain access to the pair […]
As a video game, DOOM has achieved cult status not just for its legendary gameplay and milestone developments but also because it’s the piece of software that’s likely been ported to the most number of platforms. Almost everything with a processor can run the 1993 shooter, but as it ages, this becomes less of a […]
It’s no secret that here at Hackaday we’ve at times been tempted to poke fun at the world of audiophiles, a place where engineering sometimes takes second place to outright silliness. But when a high quality audio project comes along that brings some serious engineering to the table we’re all there for it, so when […]
