Sound chips from back in the day were capable of much more than a few beeps and boops, and [InazumaDenki] proves it in a video recreating recognizable real-world sounds with the AY-3-8910, a chip that was in everything from arcade games to home computers. Results are a bit mixed but it’s surprising how versatile a […]
Fundamentally, an artificial intelligence (AI) is nothing more than a system that takes a series of inputs, makes some prediction, and then outputs that information. Of course, the types of AI in the news right now can handle a huge number of inputs and need server farms’ worth of compute to generate outputs of various […]
[Christina Ernst] executed a fantastic idea just in time for Halloween: her very own Remy the rat (from the 2007 film Ratatouille). Just like in the film Remy perches on her head and appears to guide her movements by pulling on hair as though operating a marionette. It’s a great effect, and we love the […]
To capture an instant on film or sensor with a camera, you usually need a fast shutter. But alternately a flash can be triggered with the scene in the dark and the shutter wide open. It’s this latter technique which PetaPixel are looking at courtesy of the high-speed class at Rochester Institute of Technology. They’re […]
Whether you have full use of your hands or not, a foot-operated keyboard is a great addition to any setup. Of course, it has to be a lot more robust than your average finger-operated keyboard, so building a keyboard into an existing footstool is a great idea. When [Wingletang]’s regular plastic footrest finally gave up […]
It may be the last gasp of summer here in the Northern Hemisphere, but it’s always cold somewhere, whether it’s outdoors or inside. If you suffer from cold, stiff hands, you know how difficult it can be to work comfortably on a computer all day. Somehow, all that typing and mousing does little to warm […]
Sometimes off-the-shelf solutions to a problem don’t meet your expectations. That’s what led [TomGoff] to build his own solar pond fountain. This build features a lot of creative reuse of materials [TomGoff] already had on hand, like the end of a cable reel for the platform and a wheelbarrow inner tube for flotation. A 3D […]
Standardization might sound boring, but it’s really a great underlying strength of modern society. Everyone agreeing on a way that a certain task should be done saves a lot of time, energy, and money. But it does take a certain amount of consensus-building, and at the time [JC]’s HVAC system was built the manufacturers still […]
We have to admit, we like airships. There’s something about the image of a stately zeppelin floating over Manhattan that just makes us imagine the future. There are not many airships anymore, but you can always build your own. [Crafty Robot] shows how to use one of their boards to make a simple and easy […]
We’ve noticed a rash of builds of [ FedorSosnin’s] do-it-yourself 3D-printed mechanical keyboard, SiCK-68 lately. The cost is pretty low — SiCK stands for Super, Inexpensive, Cheap, Keyboard. According to the bill of materials, the original cost about $50. Of course, that doesn’t include the cost of the 3D printer and soldering gear, but who […]
