[ad_1] We’re tremendously excited to be able to announce that the Hackaday Supercon is on for 2024, and will be taking place November 1st through the 3rd in sunny Pasadena, California. As always, Supercon is all about you, the Hackaday community. So put on your thinking caps because we’d like to hear your proposals for […]

[ad_1] “They just don’t build ’em like they used to” is a truer statement every year. Whether your vice is CRTs, film cameras, or tape decks, you’ll know that the very best gear simply isn’t manufactured anymore. Even the day-to-day stuff from 60 years ago is often a cut above a lot of today’s equipment. [Anthony […]

[ad_1] Metal-oxide semiconductor field-effect transistors (MOSFETs) see common use in applications ranging from the very small (like CPU transistors) to very large (power) switching applications. Although its main advantage is its high power efficiency, MOSFETs are not ideal switches with a perfect on or off state. Understanding the three main sources of switching losses is […]

Sometimes an offhand comment can start you down the path of making something you hadn’t thought possible. For me, it was a lamentation by the DJ and coder Hoffman on Twitch about the Gravis Ultrasound, an old PC sound card […]

[ad_1] If you need to make polyurethane belts in custom lengths, it’s not too hard. You just need to take lengths of flexible polyurethane filament, heat the ends, and join them together. In practice, it’s difficult to get it right by hand. That’s why [JBVCreative] built a 3D printed jig to make it easy.  The […]

[ad_1] Operating systems! They’re everywhere these days, from your smart TV to your smartphone. And even in your microcontrollers! Enter BreadboardOS for the Raspberry Pi Pico. BreadboardOS is built on top of FreeRTOS. It’s aim is to enable quick prototyping with the Pi Pico. Don’t confuse operating system with GUI—BreadboardOS is command-line based. You’d typically […]

[ad_1] When we think about self-driving cars, we normally think about big projects measured in billions of dollars, all funded by major automakers. But you can still dive into this world on a smaller scale, as [jmoreno555] demonstrates. The build consists of a small RC car—an HSP 94123, in fact. It’s got a simple brushed […]

[ad_1] This small device enables users to feel braille through haptics Arduino Team — May 15th, 2024 For the visually impaired community, most of their interactions on mobile phones are confined to text-to-speech (TTS) interfaces that read portions of the screen aloud. Dynamic braille displays also exist as a tactile means of communication, but their […]

[ad_1] Smartphones are an integral part of life, but what if you can’t see the screen? There is text-to-speech available, but that’s not always handy and can be slow. It also doesn’t help users who can’t hear or see. Refreshable braille devices are also available, but they are expensive and not very convenient to use. […]

[ad_1] These days, you can get a fully remote-control helicopter that you can fly around your house for about $30. Maybe less. Back in the day, kids had to make do with far simpler toys, like spinning discs that just flew up in the air. [JBV Creative] has built a toy just like that with […]
