(Phys.org) —A multinational team of researchers has published a paper in the journal Nature, offering a way towards better global planning for road construction. They highlight the benefits of road building along with detriments and include maps of the world they’ve constructed that indicate where road building would be economically beneficial, where it would be ecologically harmful and where it would be both
Multi-Zone Fire Alarm System Using Mega32 Microprocessor
Posted on: 28 Aug 2014
Introduction We designed a multi-zone fire alarm system with a VT100-compatible user interface. The system is microprocessor controlled using the Mega32 microprocessor. The system communicates to the VT100-compatible user interface via a RS232 connection. A fire is detectable by a number of fire detection devices in each of as many as eight zones. High-level Design […]
Picturing Schrodinger’s cat: Quantum physics enables revolutionary imaging method
Posted on: 28 Aug 2014
Researchers from the Institute for Quantum Optics and Quantum Information (IQOQI), the Vienna Center for Quantum Science and Technology (VCQ), and the University of Vienna have developed a fundamentally new quantum imaging technique with strikingly counterintuitive features. For the first time, an image has been obtained without ever detecting the light that was used to illuminate the imaged object, while the light revealing the image never touches the imaged object.
PC-CONTROLLED SCANNING TUNNELING MICROSCOPE Using ATMega163
Posted on: 27 Aug 2014
INTRODUCTION For our final project, we designed a scanning tunneling microscope (STM) that could be used to gather information about the surface topography of metals and semiconductors at the sub-micron scale. The STM is controlled from a graphical user interface running on a PC. The user is able to set various parameters related to the […]
Yale journal explores advances in sustainable manufacturing
Posted on: 26 Aug 2014
In recent years, increasing pressure from policymakers, consumers, and suppliers has prompted manufacturers to set environmental targets that go beyond reducing the pollutants they emit from their smokestacks or discharge into rivers and lakes. Today companies must also assess environmental performance at every step in their process, from the mining of primary materials to the use and recycling of their products.
Tic-Tac-Toe on TV Using Atmel Mega163
Posted on: 26 Aug 2014
Adventures in TV land The goal of this project was to play a simple game outputted to a television via direct NTSC signal generation into a composite video input of a television. Obviously, the outputting of material to a television is the most challenging part of this project (and not one to be taken […]
Hard Drive Based AVR Programmer Using Mega163
Posted on: 25 Aug 2014
The project which we are presenting is not the project we presented in our proposal. We initially planned to build a WWVB time-code receiver, which would demodulate a 60 kHz signal and extract an extremely precise time according to the National Institute of Standards and Technology (NIST). Unfortunately, due to a weak signal and noise […]
Autonomous Car
Posted on: 23 Aug 2014
Introduction Our vehicle uses optical sensors to follow a line on the floor. Some autonomous vehicles used in manufacturing use a similar concept. Following magnetic strips embedded in the factory floor. The versatility of an optical design should be readily apparent. Since re-routing the vehicle requires no more than re-painting a line. High-Level Design Our […]

Posted on: 22 Aug 2014
(Phys.org) —Graphene has already been demonstrated to be useful in Li-ion batteries, despite the fact that the graphene used often contains defects. Large-scale fabrication of graphene that is chemically pure, structurally uniform, and size-tunable for battery applications has so far remained elusive
Safety-sensor vehicle using Mega163
Posted on: 22 Aug 2014
Introduction cars and vehicles have been integrated into society as one of the most efficient, easiest, accessible means of transportation available. But while it is a convenient and common means of transportation, it is also an incredibly dangerous mode of transport. Thousands of people die in automobile accidents each year, whether it is a collision […]
