Pre-choose the OS to boot, even before turning on the computer by toggling a switch. Now you don’t have to wait to select the os. Story Wandering Hackaday.io for projects, I stumbled upon this project(click) by Stephen Holdaway. In this project, he solved a frustrating task faced by every dual boot user, which is sitting and […]

Z-Wave is a wireless communications protocol designed for home automation, specifically to remotely control applications in residential and light commercial environments. The technology uses a low-power RF radio embedded or retrofitted into electronics devices and systems, such as lighting, home access control, entertainment systems and household appliances. The are many devices that have these RF

Introduction After starting my circuit testing with some LEDs and switches I moved up to a small 16×2 LCD screen (HD44780 controller) with the Raspberry Pi. The configuration of the LCD pins and base code for output to the 16×2 LCD screen is taken from the excellent Raspberry Pi Spy website. I’ve made a few modifications:

In the pursuit of ever-shrinking circuitry for nanotechnology electronics, increasingly smaller devices and components are being developed. Now researchers at the University of Konstanz and the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) in Germany claim to have micro-miniaturized the humble electrical switch all the way down to molecule size and proven its operation for the very first time.

GPIO, as may have been explained in other tutorials, stands for General Purpose Input/Output and a GPIO pin can be set high (taking the value 1) by connecting it to a voltage supply, or set low (taking the value 0) by connecting it to ground. The Raspberry Pi can set the pin to take either

In this instructable I describe a method for automatically resetting a Banana Pi when it freezes, or looses power and does not restart. This method will also work for the Raspberry Pi as long as the correct GPIO pins are used (which I believe are slightly different than the Banana Pi pins). The method is
