New wood-metal hybrid for lightweight construction

“Wood foam and metal sponge – can they be combined? That was the question that experts at the Fraunhofer Institute for Wood Research, Wilhelm-Klauditz-Institut WKI delved into in a project entitled “HoMe Foam” – with HoMe being a German acronym for wood-metal …

Physicists watch spin liquid turn into Mott insulator

“An international research team featuring scientists from the Terahertz Spectroscopy Lab at MIPT has made a direct observation of the Mott transition. In this phenomenon, the electrostatic repulsion of electrons in a metal causes it to lose the ability to …

Portable Function Generator on Arduino

“Function generator is a very useful tool, especially when we are considering testing our circuit’s response to a certain signal. In this instructable I’ll describe the building sequence of small, easy to use, portable function generator. Features of …

Printing with sound

“Researchers use acoustic forces to print droplets that couldn’t be printed before Harvard University researchers have developed a new printing method that uses soundwaves to generate droplets from liquids with an unprecedented range of composition and viscosity. This technique …

Researchers Develop New Method To Increase Electro-optical Device Efficiency

“Technion researchers have developed an innovative method for increasing the efficiency of electro-optical devices by increasing the interaction between light and matter. In findings published in Advanced Materials, the researchers report that they successfully implemented the method to produce a …

RF Transmitter and Receiver

“In this project, I will use RF modules with Pic 16f628a. It will be a short tutorial about rf. After you learn ho rf modules communicate with each other you can use these modules with pic microcontroller, ardunio or any …

Scientists pioneer a new way to turn sunlight into fuel

“The quest to find new ways to harness solar power has taken a step forward after researchers successfully split water into hydrogen and oxygen by altering the photosynthetic machinery in plants. This could be a great platform for developing solar …

Shen’s Spectacular Supersolder

“Carnegie Mellon University’s Sheng Shen has created a solder-like material called supersolder, with twice the thermal conductivity of conventional solders and a compliance higher by two to three orders of magnitude. In electronics, solder is used to connect two …

Simple (hardware) Watch Dog Timer for Arduino Projects

“We all use and love the Arduino boards for our projects. But sometimes it can happen, that a software or hardware error causes a lot of frustration, by stopping out little board from running 24/7. For this reason Arduino …

Simple Inclinometer With Arduino

“This project is about a simple inclinometer featuring auto rotation of display. This inclinometer can be rotated in any position keeping the digits readable even upside down! It is controlled by an Arduino 101 driven by accelerometers to read the …
