[ad_1] You’ve probably heard that a 3D printer is capable of producing its own replacement parts. Sometimes, that even includes upgraded or improved versions of the parts it was originally built with. But sometimes, it’s hard to figure out what improved really means. Think about air ducts that cool the part after printing. In theory, […]

[ad_1] The history of consumer technology is littered with things that came and went. For whatever reason, consumers never really adopted the tech, and it eventually dies. Some of those concepts seem to persistently hang on, however, such as augmented reality (AR). Most recently, Apple launched its Vision Pro ‘mixed reality’ headset at an absolutely […]

[ad_1] Adding real-time local voice controls to a SMARS Quad Mod robot with an Arduino Nano RP2040 Connect Arduino Team — August 24th, 2024 Robotics kits like the Screwless/Screwed Modular Assemblable Robotic System (SMARS) are great tools for learning more about how electronics, mechanics, and software can combine to perform useful tasks in the physical […]

[ad_1] The simple definition of a mean is that of a numeric quantity which represents the center of a collection of numbers. Here the trick lies in defining the exact type of numeric collection, as beyond the arithmetic mean (AM for short, the sum of all values divided by their number) there are many more, […]

[ad_1] Through all the generations of computing devices from the era of the teleprinter to the present day, there’s one interface that’s remained universal. Even though its usefulness as an everyday port has decreased in the face of much faster competition, it’s fair to say that everything has a serial port on board somewhere. Even […]

[ad_1] Really, [OzzieGerff] had us at “LEGO.” But then he took it to another place entirely and built a completely mechanical, nearly 100% LEGO version of Snake. And it’s just as cool as it sounds. Mind you, it’s a little hard to grok how this whole contraption works, which has been in the works for […]

[ad_1] Traditional airports spend big money to install instrument landing systems (ILS) to guide planes in safely. In places like Antarctica, though, it’s simply not possible to permanently install a massive antenna array for localization, particularly with all the ice shifting about on the regular. As covered by Flightradar24, the solution to this is to […]

[ad_1] This week on the Podcast, we have something a little different for you. Elliot is on vacation, so Tom was in charge of running the show and he had Kristina in the hot seat. First up in the news: the 2024 Tiny Games Challenge is still underway and has drawn an impressive 44 entries […]

[ad_1] [The Thought Emporium] has been fascinated by holograms for a long time, and in all sorts of different ways. His ultimate goal right now is to work up to creating holograms using chocolate, but along the way he’s found another interesting way to manipulate light. Using specialized diffraction gratings, a laser, and a few […]
