It's pretty incredible what some people can do with a Phantom Miro 320S high-speed camera and a fairly, extensive understanding of guns. This video is a follow-up to another video Smarter Every Day did where he fired a pistol underwater. In this video, he fires a modified AK-47 underwater to study how a blowback system works underwater versus air.
Have you ever had a burning desire to understand what your dog is saying? Personally, I feel it would be mostly, “Food? Walk? Toy? Food? But, seriously, food?” but that’s just me.For your average housedog, it’s not really imperative the owner understand everything the dog is trying to communicate. However, if the dog’s job is a little more intense, it could make a huge difference.
Ultrasonic waves can find bubbles and cracks in adhesive bonds holding airplane composite parts together, and now aerospace engineers can select the best frequencies to detect adhesive failures in hard-to-reach places more quickly, thanks to Penn State researchers.
I am, by nature, a very anxious person. Alright, I am a worrier—particularly when it comes to leaving the house. Did I leave the garage door open? The stove on? The hair straighter plugged in? Did I lock all the doors? Windows? And that’s just when I leave for work.
What do you get the obscenely-wealthy executive who has everything? If it’s an especially lazy exec who absolutely must sleep where he lands (his private jet), then the jetway hotel might be perfect. A private client (with the requisite bankroll and penchant for flamboyant acts of indulgent laziness) commissioned Margot Krasojevic to design this “short stay hotel hangar”....
North Korea has stopped construction work at a site meant to launch bigger and better long-range rockets, a possible sign that Pyongyang is slowing or even halting development of larger rockets, according to a new analysis of recent satellite imagery.
KRYTAR introduced a new directional coupler offering low insertion loss, high directivity and tight coupling. The new directional coupler is suitable for emerging wireless ultra-broadband designs and many test and measurement applications. These couplers can also
TDK Corporation announces the release of TDK-Lambda’s new CN50A24 series of 50W railway DC-DC converters. These quarter-brick modules operate off a wide range of DC inputs from 14.4 to 36.0VDC, which is widely used in the railway industry and for 24-volt vehicles. Available with output voltages of 5V, 12V, or 24VDC (adjustable ±10%), these fully-regulated and isolated power modules deliver exceptional performance.
If you think your workbench is impressive, check out some of the tool kits available on the International Space Station. British ISS astronaut Tim Peake posted some pictures of the range of tools the team uses to keep the station up and running. Check out more pictures at Peake's Flickr account.
Though around the world the ability to multitask is touted as a proof of superior work ethic, more than three decades of academic research has overwhelmingly demonstrated that multitasking substantially decreases the productivity of individuals. Studies show that switching between tasks can cause a loss of productivity as high as 40 percent when compared to single-tasking...
A robotics team from the University of Queensland has created two versions of a single-use UAV. The unmanned aerial vehicles, which are usually associated with clandestine military operations, are both designed to relay environmental information.
South Korea's transport ministry said Thursday it asked Asiana Airlines Inc. to review safety measures two months before an Asiana flight crash-landed in San Francisco. Kwon Yong Bok, director general of aviation safety policy at the transport ministry, said the government informed Asiana on April 30 it should hire more pilots, engineers and cabin crew...
A NASA engineer has achieved yet another milestone in his quest to advance an emerging super-black nanotechnology that promises to make spacecraft instruments more sensitive without enlarging their size.A team led by John Hagopian, an optics engineer at NASA's Goddard Space Flight Center in Greenbelt, Md., has demonstrated that it can grow a uniform layer of carbon nanotubes....
A strange glow in space has provided fresh evidence that all the gold on Earth was forged from ancient collisions of dead stars, researchers reported Wednesday. Astronomers have long known that fusion reactions in the cores of stars create lighter elements such as carbon and oxygen, but such reactions can't produce heavier elements like gold.
Here at ECN we're always looking for what's going to change the world of electrical design. This month we're focusing on new material technology. From adhesives to thermal gap pad management, we want to know what's happening in your lab and on your benches!
Astronomers have for the first time managed to determine the color of a planet outside our solar system, a blue gas giant 63 light-years away. Using the Hubble Space Telescope, an international team said the planet known as HD 189733B would look like a deep blue dot if viewed up close.
International Rectifier introduced the radiation hardened ML Series dual output DC-DC power converter platform designed for RF communication equipment such as low noise amplifiers (LNA), receivers and frequency converters used onboard satellites.
Positronic is pleased to announce the release of a new fiber optic terminus and size 8 adapter for use in its popular Combo-D connector family. The terminus conforms to the performance criteria outlined in the ARINC 801 document, which is a widely accepted commercial aerospace standard for fiber optic termini on aircraft.
This episode of ECN's Engineering Update is brought to you by Mouser Electronics. In this week's headlines: A Laser Gatling Gun: A German laser weapons hobbyist has built a proof-of-concept Laser Gatling Gun. The aluminum-bodied gun's spinning turret features six blue 1.4-watt Class 4 lasers.
The crash landing of a South Korean airliner in San Francisco has revived concerns that airline pilots get so little opportunity these days to fly without the aid of sophisticated automation that their stick-and-rudder skills are eroding. The National Transportation Safety Board, which is investigating the accident, is a long way from reaching a conclusion as to its probable cause.
IQD’s HGXO Series of surface mount oscillators is designed primarily for military applications such as smart munitions and projectile electronics although the devices can also be used in demanding industrial applications. Designed around a hermetically sealed high-shock crystal and a
Today on Engineering Newswire we’re further developing BAE systems Railgun, making a bionic eye for the blind, demonstrating robotic apes, and re-reinventing the toilet. BAE Systems was awarded a $34.5 million contract from the Office of Naval Research for further development of the Electromagnetic Railgun under Phase 2 of the Navy’s Innovative Naval Prototype program.
In noisy, energetic New York City, the pilots of a spindly plane that looks more toy than jet hope to grab attention in a surprising way: By being silent and consuming little energy. This revolutionary solar-powered plane is about to end a slow and symbolic journey across America by quietly buzzing the Statue of Liberty and landing in a city whose buildings often obscure the power-giving sun.
The hackers who knocked out tens of thousands of South Korean computers simultaneously this year are out to do far more than erase hard drives, cybersecurity firms say: They also are trying to steal South Korean and U.S. military secrets with a malicious set of codes they've been sending through the Internet for years.
The two 16-year-old girls killed in the San Francisco plane crash were close friends and top students who were on Asiana Flight 214 for the same reason: to get a taste of American education and possibly brighten their futures. Wang Linjia showed talent in physics and calligraphy; Ye Mengyuan was a champion gymnast who excelled in literature...
