The wheels of research never stop turning, with scientists from around the world reporting countless new innovations to make our world better. Today we’ll focus on six recently released studies that cover a wide range of topics, from materials science to AI-enabled brain interfaces. Engineers from UC Berkeley and UC San Francisco have leveraged AI models in conjunction with brain-sensing devices to stream speech directly from the brain, facilitating natural speech for people affected by paralysis.

HiI am looking for a simple guide to building dc power supplies for projects. Many years agoI read a book called "Practical Solid State Circuit Design" by Jerome Oleksy. It was very straightforward and easy to understand. Can't find it any where. Does anyone know where I might finda free download of that book or find a comparable guide? Thanks

Because in a previous stage of the circuit I am trying to eliminate what is common to both the left and right channels of a stereo input - typically voice - I have to consider that I have dropped off some bass. So I figured I would (optionally) include a low-pass filter in hopes of increasing the presence of the ~234Hz range. Does this appear as though it'd work?

Hi.A single phase 1/2HP motor selectable to wire/run on 115VAC or 230VAC. 8A/4A It is a 3450 RPM out of a deceased cracked water pump. Wire colors are faded, Has one capacitor and centrifugal switch. How many windings should have ? Two? Four? More? Thin gauge and thick gauge coils? All same? Motor ran until opened to replace bearing and lubricate. Now buzzes loud when powered. Something may be disconnected by its wiring terminals. Any foolproof method to learn about it and identify winding ends ?

At Embedded World 2025, Taoglas showed off six new multi-band GNSS modules for future IoT-GNSS applications. While GNSS technology is fairly mature, the integration of amplifiers, filters, receivers, and antennas can pose a challenge to designers, especially as devices continue to shrink in size. To address these limitations, Taoglas’s newest front-end modules offer a highly integrated RF front end in a small package.

Hey everyone,I’ve been searching for a good free streaming app to watch movies and TV shows, but it’s getting overwhelming with so many options out there. I recently came across a platform called BeeTV (https://bee-tv.app) and was wondering if anyone here has used it before? Is it safe to use? Does it have a decent selection of movies and shows without too many issues? I don’t want to waste time downloading something that doesn’t work well.
