Intel’s new cameras add human-like 3D vision to any machine
They’re ready-to-use devices meant for makers and educators.

Intel has released two ready-to-use RealSense depth cameras, the D415 and the D435, that can add 3D capabilities to any device or machine. They both come in a USB-powered form factor and are capable of processing depth in real time, thanks to the chipmaker’s new RealSense vision processor D4.

Intel says the cameras’ target audiences aren’t just developers and manufacturers, but also makers and educators, since they’re easy to use and will work as soon as you plug them in. Also, it comes with Intel’s RealSense SDK 2.0, which is now a cross-platform, open source SDK.

The D415 and the D435 are now available for pre-order for $149 and $145, respectively. D415 has a narrow field of view and a rolling shutter that scans its environment from one side to the other to take an image. It works best when dealing with small objects and anything that needs precise measurements. D435, on the other hand, has a wider field of view and has a global shutter that takes images all at once.

A couple years ago, Hasselblad released a 200-megapixel, Multi-Shot version of its H5D medium format camera. Now it’s back with a bonkers, 400-megapixel version of the H6D: the H6D-400c.

Hasselblad’s Multi-Shot technology is pretty straightforward: it takes four 100-megapixel images, shifting the sensor by one pixel for each capture, and then two more shots that shift the sensor by half a pixel. By combining all six stills, the resulting file is a single 400-megapixel (23200 x 17400 pixel) 16-bit TIFF file that weighs in at 2.4GB.

Now there’s finally a MEMS loudspeaker A company called USound has developed the first loudspeaker that isn’t just a bunch of wire and a magnet. This is a speaker built from a silicon wafer that can be as small as 3 mm square, and as thin as 1 mm. Since these speakers are built on silicon, you can also add an amp right onto the package. This is quite literally a speaker on a chip, and we’d bet that there are already engineers at Samsung looking at stuffing this into a flagship phone.

Ever wanted to stream prerecorded music or a live event, such as a lecture or concert for an internet audience? With Icecast and Liquidsoap, you can set up a full-featured, flexible internet radio station using free software and open standards.

Icecast is “a streaming media (audio/video) server that currently supports Ogg (Vorbis and Theora), Opus, WebM and MP3 streams. It can be used to create an internet radio station or a privately running jukebox and many things in between. It is very versatile in that new formats can be added relatively easily and supports open standards for communication and interaction.”

Liquidsoap is “a powerful and flexible language for describing your streams. It offers a rich collection of operators that you can combine at will, giving you more power than you need for creating or transforming streams. But Liquidsoap is still very light and easy to use, in the UNIX tradition of simple strong components working together.”

When combined, Icecast and Liquidsoap can create a flexible, feature-rich internet radio station. In this article, I describe how to configure Icecast to host an internet radio station. Then, I explain how to install and configure Liquidsoap to connect to Icecast, adding random (or sequential) music playback with smart cross-fading, prerecorded randomly inserted announcements and jingles, a song request system and support for live streams, with automated recording and seamless switching between live and automated programming.

From their fine range of vintage turntables and speakers to mountains of tape decks, cables and old amps, through to their fabled “prop” room, we delve into the wonderful, cavernous world of Audio Gold.

Like many people who have a solar power setup at home, [Jeroen Boeye] was curious to see just how much energy his panels were putting out. But unlike most people, it just so happens that he’s a data scientist with a deep passion for programming and a flair for visualizations. In his latest blog post, [Jeroen] details how his efforts to explain some anomalous data ended with the discovery that his solar array was effectively acting as an extremely low-resolution camera.

Our waterproof electret condenser microphones carry Ingress Protection (IP) ratings up to IP67 and feature sensitivity ratings as low as -42 dB and signal to noise ratios from 57 up to 70 dBA. These omnidirectional microphones are available in wire lead and terminal mount configurations with operating frequencies ranging from 20 to 20,000 Hz. Housed in compact packages with diameters as small as 4 mm and depths as low as 1.5 mm, our waterproof microphones are ideally suited for a variety of industrial and outdoor applications where moisture and environmental contaminants are present.

Had no idea they still make sound cards (never bothered to look) untill I watched this video. The more you know
