PORTLAND, Ore. — Scientists have demonstrated a doubling of the number of electrons produced by carbon-based photovoltaic polymer potentially doubling the efficiency of any solar cell. The process called “singlet fission” produces “identical twin” electrons from a single photon, instead of the normal one, dramatically boosting the theoretical maximum output of solar cells. Instead of […]

Here is a Simple Temperature Display Circuit using LCD (Liquid Crystal Display). For Heat Sensor we have used IC LM35 (Precision Centigrade Temperature Sensors) whose Output voltage is linearly proportional to the Celsius (Centigrade) temperature. Output of LM35 IC is 10mv/degree centigrade for eg if temperature is 35 degree, then the output of sensor will […]

One of the best capabilities provided by Arduino regards its very high modularity, which helps users to quickly translate ideas into physical artifact, as practically demonstrated by Mauro, which shows on his blog how to build a simple data-logger by properly combining different shields. By using few additional components (mainly resistors and buttons) a fully-functional […]

A research collaboration consisting of IHP-Innovations for High Performance Microelectronics in Germany and the Georgia Institute of Technology has demonstrated the world’s fastest silicon-based device to date. The investigators operated a silicon-germanium (SiGe) transistor at 798 gigahertz (GHz) fMAX, exceeding the previous speed record for silicon-germanium chips by about 200 GHz. Although these operating speeds […]

We have previously posted the the project lie detector, now here is is also a lie detector using arduino. Here is a simple tutorial to build a simple lie detector which will give visual indication through LED arrangement whether the person speaks lie or truth. The project uses a arduino duemilanove or uno. So the project is based on […]

Everyone wants to keep their home secure. If zombies have swarmed your house, you want to know it’s not safe to return, RIGHT? What better way to do this than to set up a surveillance system? Now it’s easier than ever to have. And, you don’t have to shell out hundreds of dollars to make sure […]

You can get soup in a can. You can get bread in a can (*). Now the long wait is over! You can finally get Lambda Calculus in a can. Project LambdaCan is an amusing exercise in absurdity. It implements a reducer (interpreter) for the Lambda Calculus, a formal system (programming language) developed by Alonzo […]

Researchers from the University of Manchester and University of Sheffield have developed a new prototype semi-transparent, graphene-based LED device that could form the basis of flexible screens for use in the next-generation of mobile phones, tablets and televisions. The incredibly thin display was created using sandwiched “heterostructures”, is only 10-40 atoms thick and emits a […]

Despite sounding like an alcopop, Fritzing is actually an incredible bit of free software you can use to create circuit and component diagrams for use with rapid-protoyping electronics boards such as the fantastic open-source Arduino. As such, it’s open source too, entirely cross platform and well supported – you can almost guarantee that it can […]

The original idea was to create a library that simplify the use of IC 74HC595 between Arduino and other hardware. In this Instructable I will share this to you using as example the control of a 16×2 LCD. The example will show on the LCD the seconds that has passed since Arduino was restarted. I […]
