“Researchers from North Carolina State University have developed a new technique that takes advantage of gold nanoparticles to trigger the sequential unfolding of three-dimensional structures using different wavelengths of light. Specifically, the technique makes use of the fact that different …
“New bolometer is faster, simpler, and covers more wavelengths. Bolometers, devices that monitor electromagnetic radiation through heating of an absorbing material, are used by astronomers and homeowners alike. But most such devices have limited bandwidth and must be operated at …
“A team from the University of Southampton has invented a new way for designing electronic systems that incorporates the best from both analogue and digital paradigms. The approach combines the computational power of analogue with the energy benefits of digital …
“Do you sometimes wonder how polluted the air inside your house is? Our surroundings are constantly degrading, and there are innumerable disease that can be caused by living in unhealthy, impure and polluted surroundings. I know there are a number …
“This is a simple two micro-servo and Arduino Uno controlled drum machine or robot. The servos are mounted on an L-shaped bracket of wood that is held to the snare drum with 4 strong magnets. The servo arms are bolted …
“Army scientists proved a decades-old prediction that mixing TNT and novel aluminum nanoparticles can significantly enhance energetic performance. This explosive discovery is expected to extend the reach of U.S. Army firepower in battle. Researchers from the U.S. Army …
“Wireless smart-home system from the Computer Science and Artificial Intelligence Laboratory could monitor diseases and help the elderly “age in place.” X-ray vision has long seemed like a far-fetched sci-fi fantasy, but over the last decade a team led by …
“This shelf features 2 glass shelves, behind which lay strips of LEDs that can be controlled using an android phone and the app I wrote. They can be set to any RGB color combination, as well as several moving color …
“Story Character LCDs are one of the most common things one gets in an Arduino kit. They are very cheap and fun to work with. They are categorized in two categories: one that is directly hooked up to the Arduino …
“Superconductors contain tiny tornadoes of supercurrent, called vortex filaments, that create resistance when they move. This affects the way superconductors carry a current. But a magnet-controlled “switch” in superconductor configuration provides unprecedented flexibility in managing the location of vortex filaments …
