Artificial Intelligence came up with new solutions to quantum experiments. (Image Credit: Pixabay)   Mario Krenn, a Quantum physicist, developed a machine-learning algorithm named MELVIN, purposed to discover new solutions to quantum experiments while mixing and matching its building blocks. Along the way, MELVIN discovered some intriguing solutions, but one of them didn't make sense. In this context, MELVIN solved the problem of building extremely complex entangled states involving multip ...
The Sentinel-6 satellite launched from Vanderberg Air Force Based in California. (Image Credit: NASA/JPL-Caltech)   While the climate changes, Earth’s oceans are rising and warming up. For three decades, satellites have been orbiting the Earth to monitor the seas. The most recent satellite, Sentinel-6 Michael Freilich, has started providing precise measurements of Earth’s rising sea level. The satellite, named after NASA’s late climate scientist Michael Freilich, launched ...
NICT engineers developed a four-core fiber optic cable that can deliver speeds at 319 Tb/s, shattering the previous 178 Tb/s world record. (Image Credit: Denny Muller / Unsplash)   Engineers at the National Institute of Information and Communication Technology (NICT) managed to break the 178 Tb/s internet speed record with a 319 Tb/s achievement. The team reached this milestone while maintaining the speed at over 1,865 miles without performance loss.   The 178 Tb/s speed involved usi ...
The key is inserted into the lock, which produces a sound as the pin slips off a key ridge. (Image Credit: National University of Singapore)   This is kind of scary. Also seems like a super cool Bond device.   It can be easy enough to pick keyed locks, but a new-found technique makes it much easier. Researchers at the National University of Singapore have discovered that by using a smartphone to record a key’s sound in a lock, you can capture all the needed information to creat ...

Mains Power Monitor

Posted by alfiesmith Jul 13, 2021
A friend of mine wanted to keep logs of his power consumption. He also wanted to make sure the wattage of appliances is what they state they are. As he has not got a smart meter (even if he did, there would not be a log every second), he asked if I could come up with a solution. He would prefer it to be Wi-Fi, so the P.C. does not have to be moved next to the power monitor. So, the Mains Power Monitor was developed. It uses an ESP32 module with integrated Wi-Fi. I am using a Wroom version, ...
Cornell University researchers reconstructed the EMPAD’s data with algorithms to capture a high-resolution image of atoms in a praseodymium orthoscandate crystal. (Image Credit: Cornell University)   Cornell University researchers recently captured a high-resolution 3D image of atoms in a praseodymium orthoscandate crystal, zoomed in 100 million times. The feat, achieved through an electron microscope pixel array detector (EMPAD), doubled its world record image resolution set in 2018 ...
The device, designed to prevent internal bleeding from a stab wound, contains a tamponade and an actuator. (Image Credit: Loughborough University)   Joseph Bentley, a Loughborough University student, recently developed REACT, a 3D-printed prototype that prevents further blood loss from a serious knife-inflicted stab wound. Stab wounds could turn out to be a matter of life or death, so it’s crucial to apply immediate internal pressure. REACT (Rapid Emergency Actuated Tamponade) is spe ...
EyeHarp allows people with disabilities to play music with their eye movement. A user rests their eye on a musical note spaced out on a wheel on the screen. (Image Credit: EyeHarp)   Alexander Kerlidou, a student with cerebral palsy who cannot use her hands or speak, performs harp music just by shifting her eyes across a computer screen.  The eye-moving-controlled software, EyeHarp, allows disabled people to play music, which the 21-year-old deemed impossible. Alexander, who wants to ...
