Growth under pressure: New metamaterial designed with counterintuitive property

” In the not-too-distant future, it may be possible to 3-D print virtually anything. Consider standard printers, which “synthesize” thousands of colors by using only three color cartridges. By analogy, future 3-D printers may be capable of synthesizing thousands of different …

How to Make an Electric Go Kart

“In this Instructable I will be showing you how I transformed an old gas powered go kart into an electric go kart. This project was very time consuming and I am very happy to finally share it with all of …

Led Cube 5x5x5 (Arduino Project)

“In this project I will show you how to build a simpler version of a 5x5x5 LED Cube. I’m providing a full step-by-step guidance to show you how to make your own LED Cube, and I explaining in details …

LoRa IOT Home Environment Monitoring System

“The LoRa IOT Home Environmental Monitoring System consists of an Arduino Mega based IOT-to-Internet gateway and Arduino Feather based remote stations with environmental sensors. The remote stations communicate wirelessly with the gateway using LoRa radios. The system enables a …

Not stuck on silicon

“In 2016, annual global semiconductor sales reached their highest-ever point, at $339 billion worldwide. In that same year, the semiconductor industry spent about $7.2 billion worldwide on wafers that serve as the substrates for microelectronics components, which can be …

Rechargeable ‘spin battery’ promising for spintronics and quantum computing

“Researchers have shown how to create a rechargeable “spin battery” made out of materials called topological insulators, a step toward building new spintronic devices and quantum computers. Unlike ordinary materials that are either insulators or conductors, topological insulators are both …

Arduino Fastest Reaction Time Game for 1-4 Players
