Exclusive: Lytro Reveals Immerge 2.0 Light-field Camera with Improved Quality, Faster Captures

Posted by in categories: electronics, virtual reality

Lytro’s Immerge light-field camera is meant for professional high-end VR productions. It may be a beast of a rig, but it’s capable of capturing some of the best looking volumetric video that I’ve had my eyes on yet. The company has revealed a major update to the camera, the Immerge 2.0, which, through a few smart tweaks, makes for much more efficient production and higher quality output.

Light-field specialist Lytro, which picked up a $60 million Series D investment earlier this year, is making impressive strides in its light-field capture and playback technology. The company is approaching light-field from both live-action and synthetic ends; last month Lytro announced Volume Tracer, a software which generates light-fields from pre-rendered CG content, enabling ultra-high fidelity VR imagery that retains immersive 6DOF viewing.

Ultracompact camera is the size of a salt grain

Posted by in category: electronics

U.S. researchers have developed a new imaging device just 500 μm (0.5 mm) in diameter. The system can produce crisp, full-colour images on a par with conventional compound camera lenses 500,000 times larger in volume.

Thermoelectric crystal conductivity reaches a new high

Posted by in categories: electronics, materials

Just as a voltage difference can generate electric current, a temperature difference can generate a current flow in thermoelectric materials governed by its “Peltier conductivity” ℗. Now, researchers from Japan demonstrate an unprecedented large P in a single crystal of Ta2PdSe6 that is 200 times larger than the maximum P commercially available, opening doors to new research avenues and revolutionizing modern electronics.

We know that current flows inside a metallic conductor in presence of a voltage difference across its ends. However, this is not the only way to generate current. In fact, a difference could work as well. This phenomenon, called “Seebeck effect,” laid the foundation of the field of thermoelectrics, which deals with materials producing electricity under the application of a temperature difference.

Similar to the concept of an electrical conductivity, thermoelectricity is governed by the Peltier conductivity, P, which relates the thermoelectric current to the temperature gradient. However, unlike its electrical counterpart, P is less explored and understood. For instance, is there a theoretical upper limit to how large P can be? Far from being a mere curiosity, the possibility of a large P could be a game changer for modern-day electronics.

Breakthrough “Smoking Gun” Discovery in Power Consumption in Electronic Devices

Posted by in categories: electronics, innovation

In a new FLEET theoretical study published recently in Physical Review Letters, the so called ‘smoking gun’ in the search for the topological magnetic monopole — also known as the Berry curvature — has been found.

The discovery is a breakthrough in the search for topological effects in non-equilibrium systems.

The group, led by UNSW physicist and Associate Professor, Dimi Culcer, identified an unconventional Hall effect, driven by an in-plane magnetic field in semiconductor hole systems that can be traced exclusively to the Berry curvature.

A New Electronic Warfare System Can Take Down Several Threats at Once

Posted by in categories: electronics, military

Behold Israel’s multitasking skills.

In a world where weapon systems heavily depend on advanced electronics and technology to coordinate attacks, it makes sense to deploy highly reusable and cheap electronic warfare (EW) tactics to counter them. An Israel-based manufacturer of such systems, Israel Aerospace Industries (IAI), has now introduced the ability to target multiple threats simultaneously.

Although electronic warfare is a new age weapon system, designers of the technology still follow the archaic methods of ‘point and shoot,’ severely limiting their targeting capacity. Not only does one need more weapon systems to counter a larger threat, but the response time also ends up being longer when you are targeting your threats in a serial order. IAI’s new offerings have fundamentally changed how electronic warfare systems are perceived and how they ought to work.

Neuromorphic electronics based on copying and pasting the brain

Posted by in categories: electronics, neuroscience

This Perspective explores the potential of an approach to neuromorphic electronics in which the functional synaptic connectivity map of a mammalian neuronal network is copied using a silicon neuro-electronic interface and then pasted onto a high-density three-dimensional network of solid-state memories.

Visualizing Audio With An LCD VU Meter

Posted by in categories: electronics, media & arts

We all love seeing data represented in pretty ways — whether it’s necessary or not. Take VU meters for example. They’re a super useful tool for audio editors to balance signals, but they also look really cool, even if you’re only listening to music. Who didn’t use a Winamp skin with a built-in VU meter back in the day? Even after the demise of everyone’s favorite media player, we still see these great graphs popping up all over the place.

Most recently, we’ve seen VU meters circle back around to have a bit of a retro vibe in this awesome Arduino-controlled LCD VU meter built by [mircemk]. Based on the KTAudio VU Meter project, it features an ultra-wide LCD, audio input, and volume knob, all tidily wrapped up in a case whose color scheme that can only conjure images of the famed Altair 8800, or an old Tektronix oscilloscope. The LCD itself is fairly responsive — but you can judge for yourself in the video below. The signature fading that so commonly accompanies screen refreshes on LCDs such as this one really adds to the retro effect.
