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.

Green hydrogen is touted to be one of the essential ingredients for the sustainable energy mix of the future. Yet, there’s an…invisible…yet big problem. Storage, transport, and operation is complicated and expensive, but what if we could create and store solid hydrogen for cheap? A start-up may have a solid technology that could speed up the energy transition. Spoiler: It’s so good it was banned!

Qualcomm is Preparing Developers for the Coming Wave of Smartphone-tethered AR Glasses

Posted by in categories: augmented reality, mobile phones

Today at AWE 2,021 Qualcomm announced Snapdragon Spaces XR Developer Platform, a head-worn AR software suite the company is using to kickstart a broader move towards smartphone-tethered AR glasses.

Qualcomm says its Snapdragon Spaces XR Developer Platform offers a host of machine perception functions that are ideal for smartphone-tethered AR glasses. The software tool kit focuses on performance and low power, and provides the sort of environmental and human interaction stuff it hopes will give AR developers a good starting point.

Rolls-Royce’s mtu hydrogen fuel cell module can power ten homes

Posted by in categories: climatology, computing, sustainability

With a minimalistic design and H-shaped front panel, the new mtu hydrogen fuel cell is a complete solution for power supply in the megawatt range that will be produced in series from 2025. This modern-looking module will in the future deliver a net power output of around 150 kW – sufficient to power approximately ten homes. It can also be connected together into scalable fuel cell power plants with outputs in the megawatt range – capable of providing clean backup power for large data centers.

The fuel cell module is the result of collaboration between Rolls-Royce and cellcentric, a joint venture company set up by Daimler Truck AG and Volvo Group AB earlier this year. It is based on cellcentric’s fuel cell modules that emit nothing other than water vapor. This will enable CO2-free, climate-neutral generation of emergency power for data centers.

“Electrical generators based on fuel cells represent the next leap forward in the energy transition, both for our customers and us,” said Andreas Schell, CEO of Rolls-Royce Power Systems. “That’s why we’re investing a three-digit million amount in R&D over the next few years, and we hope that this strong commitment will encourage governments and politicians to promote and support this pioneering, extremely climate-friendly technology. When they run on green hydrogen, meaning hydrogen made using renewable energy sources, fuel cells are climate-neutral. For this reason, and also because we’re simply convinced by fuel cell technology, we also want to look into how green hydrogen can be produced cost-effectively in the quantities we need.”

Nvidia’s new tech uses AI to automatically match voice lines to animated faces

Posted by in categories: robotics/AI, transportation

Nvidia may be best known for graphics cards you can’t find in stores, but the company also makes some interesting software tools. An example of this is the noise removal feature known as RTX voice, which was upgraded to work with all GeForce cards earlier this year, and does an excellent job of cleaning up background noise.

Now Nvidia (Thanks, 80.lv) has been showing off a new tool in beta this year involving sound. Audio2Face is an impressive looking auto rigging process that runs within Nvidia’s open real-time simulation platform, Omniverse. It has the ability to take an audio file, and apply surprisingly well matching animations to the included Digital Mark 3D character model.

This New Personal Flying Vehicle Prototype Can Fly You At Speeds Up To 160MPH

Posted by in categories: sustainability, transportation

Beats road traffic any day.

As the world progresses towards electric vehicles and flying cars, a team of researchers from the Washington State University is working with ZEVA Aero, a Tacoma-based start up to test different components to create a single passenger, electric vertical takeoff and landing (eVTOL) aircraft.

It’s interesting to note that ZEVA Aero has already completed a functional prototype of a very futuristic looking eVTOL vehicle which has been assigned to use by first responders and emergency services before the general public. The prototype is capable of flying at 160 mph for up to 50 miles (80km). When it takes off from the ground, it hovers just like a helicopter and then tilts horizontally to fly more efficiently like a plane. This enables it to take advantage of the reduced drag and travel at faster speed as compared to other eVTOL vehicles.

Japanese Inventor Built a Machine That Turns Plastic Bags into Oil

Posted by in categories: energy, transportation

Japanese inventor, Akinori Ito, has created a household appliance which converts plastic bags into fuel for heat generators and some stoves.


Let’s talk numbers. On average, Americans use 100 billion plastic bags a year, which are produced with 12 million barrels of oil. When you think about the fact that one plastic bag takes 1,000 years to degrade, that’s a lot of waste lying around in landfills or poured into the ocean. What’s worse is that these plastic bags don’t even break down completely. They get polluted by the sunlight and turn into microplastics that absorb toxins, polluting the environment.

Regeneron’s COVID antibody drug shows protection for up to 8 months

Posted by in categories: biotech/medical, law enforcement

The antibody therapy, REGEN-COV, is currently authorized in the United States to treat people with mild-to-moderate COVID-19 and for prevention of infection in those exposed to infected individuals, and others at high risk of exposure in settings such as nursing homes or prisons. [USN: L4N2P640O]

The extended authorization could help boost sales of Regeneron’s antibody cocktail, in the face of competition from oral COVID-19 pills such as those being developed by Pfizer Inc (PFE.N) and Merck & Co (MRK.N).


Regeneron Pharmaceuticals Inc said on Monday a single dose of its antibody cocktail reduced the risk of contracting COVID-19 by 81.6% in a late-stage trial, in the two to eight months period following the drug’s administration.

Autonomous robot performs its first intramuscular injection without needles

Posted by in categories: biotech/medical, robotics/AI

One of the things that many people hate most about getting vaccinations and taking certain types of medication is needles. Any medication that has to be delivered intramuscular typically requires a needle and a skilled medical professional to administer it. However, that may change in the future with a new autonomous robot created by a company called Cobionix, founded at the University of Waterloo.

The autonomous robot utilizes the company’s Cobi platform to perform injections without using needles. Cobi is described as a versatile robotic platform that can be deployed rapidly and complete tasks completely autonomously. The robot was fitted with a needle-free injection system. It demonstrated the ability to deliver intramuscular injections to patients without needing needles and without supervision by a healthcare professional.
