“Where I live, school was suspended in March, and our classes were moved online. That was okay and everything, but when it came to science, all the labs went out the door. (Virtual labs just aren’t the same, if …
” It is basically a small scaled digital oscilloscope. It is capable of displaying all type of waveform like sine, triangular, square, etc. It’s bandwidth is above 1 MHz and input impedance is about 600K. The device is mainly using …
“A team of physicists and chemists has produced the first porous graphene ribbons in which specific carbon atoms in the crystal lattice are replaced with nitrogen atoms. These ribbons have semiconducting properties that make them attractive for applications in electronics …
““Light squeezer” reduces quantum noise in lasers, could enhance quantum computing and gravitational-wave detection. Physicists at MIT have designed a quantum “light squeezer” that reduces quantum noise in an incoming laser beam by 15 percent. It is the first system …
“This project is only free for personal and non-commercial use AC loads live with us! Because they are everywhere around us and at least home appliances are supplied with the mains power. Many types of industrial equipment are also powered …
“ESA’s cubic-metre-sized Proba-V minisatellite, seen left, has ended its seven-year global mission to monitor the daily growth of all Earth’s vegetation, a task being taken up by Copernicus Sentinel-3 instead, seen right. Proba-V was launched in 2013 to …
“Here is a fun reaction timer game using a few of the parts from an Elegoo Uno Super Starter Kit. This is a fun reaction timer game using a 4 digit 7-segment LED display an Arduino and a button. Challenge …
“Novel red LEDs are more temperature stable than those made using the conventional semiconductor of choice. In efforts to optimize the performance of light-emitting diodes (LEDs), KAUST researchers are looking at every aspect of the design, fabrication and operation of …
“This project was inspired by my dad’s university digital systems project from the late 1970’s. I found the writeup and schematic and decided to try and re-create it. You can see the results of the breadboard reproduction and …
“Things are different on the other side of the mirror. Text is backward. Clocks run counterclockwise. Cars drive on the wrong side of the road. Right hands become left hands. Intrigued by how reflection changes images in subtle and not-so-subtle …
