Arduino Based USB Paper Gesture Mouse

“I have always been pretty amazed by the Capacitive sensor library of Arduino, It makes me feel like a super human, I can make any non conductive material to act like a touch enabled controller for various use cases, So …

ATtiny85 EMF Detector

“This is a simple tutorial to create an EMF detector using an ATtiny85 microcontroller. This is a simple tutorial to create an EMF detector. You can use Arduino for this job, but is better use a microcontroller called ATtiny85. It …

Automation With Esp8266 Using Relays

“Today, we are going to program the ESP8266 with the Arduino IDE. Let’s set up a server to turn on and off the device. In this case, we are using a circuit with two relays. In this circuit, we …

Controlled coupling of light and matter

“Researchers from Würzburg and London have built the foundations for a new field of nano-optics: they have succeeded in controlling the coupling of light and matter at room temperature. Publishing in a journal like Science Advances usually heralds a particularly …

Dual Frequency Comb Generated on a Single Chip Using a Single Laser

“Columbia Engineers are the first to miniaturize dual-frequency combs by putting two frequency comb generators on a single millimeter-sized silicon-based chip; could lead to low-cost, portable sensing and spectroscopy in the field in real-time In a new paper published today …

Ethereum’s smart contracts are full of holes

“Blockchain-powered computer programs promise to revolutionize the digital economy, but new research suggests they’re far from secure. Computer programs that run on blockchains are shaking up the financial system. But much of the hype around what are called smart …

Going with the DNA flow: Molecule of life finds new uses in microelectronics

“For sheer versatility, there’s no molecule quite like DNA. The iconic double helix carries the genetic blueprint for living forms ranging from single-celled organisms to human beings. Recently, researchers have found that DNA’s remarkable properties of self-assembly and …

How To Control A Servo Using Grbl

“GRBL is an arduino program for controlling each of the XYZ stepping motors on 3-axis machines such as 3D-printers and milling machines. [1] If you study the predefined GRBL pin-outs in photo 2 you will see that none of the …

Insulator or superconductor? Physicists find graphene is both

“When rotated at a “magic angle,” graphene sheets can form an insulator or a superconductor. It’s hard to believe that a single material can be described by as many superlatives as graphene can. Since its discovery in 2004, scientists …

Intelligent rotor blade optimizes wind energy utilization

“The share of the overall electricity market made up by wind energy continues to grow year after year. The giant rotor blades are one central part of a turbine. In the “SmartBlades” project, the Fraunhofer Institute for Wind Energy Systems …
