http://www.iflscience.com/physics/physicist-uses-regular-digital-camera-to-photograph-a-single-atom/ In 2012, Australian physicists captured the first image of a single atom. The process was painstaking and required a super-high resolution microscope. A new photograph taken by Oxford University physics PhD candidate David Nadlinger using only an ordinary digital camera shows a single, glowing-blue strontium atom hovering within a powerful vacuum chamber. It earned →

https://www.phoronix.com/scan.php?page=news_item&px=MPEG-2-Last-Patents-Expire Just the last of the MPEG-2 patents have now expired few days ago. From the MPEG LA: Please note that the last US patent expired February 13, 2018, and patents remain active in Philippines and Malaysia after that date. This does not mean that the usefulness of the MPEG-2 has ended for technology users. →

https://opensource.com/article/18/2/open-source-audio-visual-production-tools Open source is well established in cloud infrastructure, web hosting, embedded devices, and many other areas. Open source is also a great option for producing professional-level audio-visual materials. The list is divided into graphics, audio, video, and animation solutions →

Here are some audio and video trends for 2018. Buying headphones in 2018 is going to be a fragmented mess because of a silent goodbye to the 3.5mm audio plug, Majority of new headphones introduced at CES were wireless and there are several different wireless systems. Bluetooth audio has historically sacrificed sound quality for convenience →

This is a video of an amazing light projection that was in public display in Helsinki just few days ago at LUX Helsinki annual light festival. Janne Ahola’s installation Time’s Role aims to break down the physical boundaries of perspective. It brings the courtyard façade of the Museum of Finnish Architecture to life by using →

Audio jacks have been around for decades and have been used in a wide variety of applications. While simple in their basic functionality, they can be used in complex systems. Understanding Audio Jack Switches and Schematics document will help you understand some of their capabilities and will dig into the “guts” of these connectors.When looking →

https://m.phys.org/news/2017-12-breakthrough-sensor-photography-life-sciences.html Engineers from Dartmouth’s Thayer School of Engineering have produced a new imaging technology that may revolutionize low light imaging. Called the Quanta Image Sensor, or QIS, this new light sensing technologyenables highly sensitive digital imaging in low light situations. QIS technology is able to reliably capture and count single photons, with resolution as high as one megapixel.  This →

Elisa Viihde is a IPTV service sold by Finnish telecom operator Elisa. The system works so that you have a set-top-box that connect to your cable TV and your Internet connection. You can use the set-top-box to view both live cable TV signal, your recorded TV programs from IPTV video recorder (in “cloud”), pay TV →

https://m.dpreview.com/news/2842585992/researchers-teach-algorithm-about-textures-to-create-high-res-versions-of-low-res-images Upsampling image and video files usually leads to pixelation and soft textures, simply because algorithms are not capable of replacing non-existing image detail. But scientists at the Max-Planck Institute for Intelligent Systems in Germany have come up with a clever solution that is capable of producing better results than anything we’ve seen so far. →

The Valve Wizard web page is about tube amplifiers. They have a very good document on grounding issues in tube circuits. So read their 16 page Grounding document to learn about grounding (both general information and tube amplifier specific information).   →
