“Rutgers-led research could help reduce energy use, improve electronic devices When two mesh screens are overlaid, beautiful patterns appear when one screen is offset. These “moiré patterns” have long intrigued artists, scientists and mathematicians and have found applications in printing …
“Here is the finished Seven Segment Tester. All of the available Arduino Nano pins, except for analog input pins A6,A7 and Serial Port pins D0 and D1 are connected. This leaves us with 18 pins to bring to the …
“Los Alamos National Laboratory scientists have developed a new quantum computing algorithm that offers a clearer understanding of the quantum-to-classical transition, which could help model systems on the cusp of quantum and classical worlds, such as biological proteins, and also …
“Controlling how electrons zip through a material is of central importance to build novel electronic devices. How the electronic motion is affected by magnetic fields is an old problem that has not been fully solved, yet has already led to …
“At the Korea Institute of Science and Technology, Dr. Hyunjung Yi of the Post-Silicon Semiconductor Institute and her research team have developed a transfer-printing technology that uses hydrogel and nano ink to create high-performance sensors on flexible substrates of diverse …
“Oxide layer atop nanometal layer results in electron shuttle, not corrosion Scientists from Northwestern University and Caltech have produced electricity by simply flowing water over extremely thin layers of inexpensive metals, including iron, that have oxidized. These films represent an …
“RG Tic Tac Toe is a classical game can be made in diverse versions. But, I decided to build it with common cathode RG LEDs of 5mm as monitor of results so that once manipulated the respective switch, the LED …
“Rotary phones are fun, the inginuity of the dial in combination with the phone centrals elektromechanical logic made it possible to allow telecommunications to evolve. These wonderfull devices are now disapearing from our desks (for many good reasons). But wouldn …
“I have in my hand a distance laser sensor with high precision and speed. It is used in industrial environments for object positioning or detection applications. According to technical documents, I found it can communicate with other devices via RS485 …
“Welcome to the first edition of Science of Sound Laboratory Manual, an open educational resource (OER). The goal of this work is to support the lab portion of a general college physics course that focuses on sound, acoustics and audio …
