Alphanumeric Optical Endec Transceiver Using Atmega644
Posted on: 17 Aug 2015
Introduction Our goal in this project was to build a pair of high-speed transceivers that could encode and decode optical signals modulated using Morse code conventions. The project involved a few interesting challenges that we believed would be interesting to tackle. Interfacing a camera with a microcontroller is a difficult thing to do, due to […]
Optical microphone and spectrum analyzer Using Atmega1284
Posted on: 16 Aug 2015
We implemented an optical microphone which converts distant vibrations, including sound, to an audio signal. Measuring the reflection of a laser beam from windows or glass, it possible to hear sounds near the target. The system also includes frequency spectrum analysis with a real-time display and user-configurable ranges, and it also has an output for […]
Report: Documents reveal details behind AT&T-NSA partnership
Posted on: 16 Aug 2015
Under a decades-old program with the government, telecom giant AT&T in 2003 led the way on a new collection capability that the National Security Agency said amounted to a “‘live’ presence on the global net” and would forward 400 billion Internet metadata records in one of its first months of operation, The New York Times reported.
IFF System for Infantry Using Atmega1284
Posted on: 15 Aug 2015
Introduction “An encrypted laser-based friend-foe identification system to prevent friendly fire in battle” This project implements an Identification Friend-or-Foe (IFF) system for use by soldiers to prevent friendly-fire. The inspiration for the project is derived from Identification Friend-or-Foe (IFF) transponder systems currently used on fighter aircraft and military vehicles. Fighter aircraft fitted with an IFF […]
New survey on Americans' foreign policy priorities
Posted on: 14 Aug 2015
Americans favor diplomatic and economic strategies over military involvement in foreign policy, according to a new national survey conducted by The Associated Press-NORC Center for Public Affairs Research. Americans also question whether or not the United States should be the world’s chief problem solver, even as a myriad of issues across the globe are identified as important for the next president to address.
Persistance of Vision Clock Using Atmega644
Posted on: 13 Aug 2015
The goal of our project was to create a persistence-of-vision (POV) analog clock using an LED display. The clock has a visual alarm system which lights up the entire display for two seconds if it reaches an alarm time. The current time and alarm times are preset into the clock before it begins to spin. […]
Migratory patterns of eastern Golden Eagle population revealed
Posted on: 12 Aug 2015
Eastern North America is home to a small population of Golden Eagles (Aquila chrysaetos), but despite their potential vulnerability to habitat loss and other threats, little information has been available on the patterns of their annual migration. One big question is whether or not they exhibit “migratory connectivity,” where individuals from the same breeding area also migrate to the same wintering area; strong connectivity means that a population is divided into small subpopulations that are especially vulnerable to environmental changes.
Virtuoso: A Touchscreen Music App Using Atmega644
Posted on: 12 Aug 2015
n our final project, we designed an electronic multifunction instrument with a LCD touch screen and a microphone. The user can play three kinds of instruments on it — xylophone, flute and piano. Each instrument has a different interface and timbre. The piano part has a record/replay function which can echo the song previously played […]
NFC Secure Data Storage Using Atmega644
Posted on: 11 Aug 2015
Summary “Enabling secure storage capabilities for sensitive data through standardized methods of encryption or multiple agent distribution.” Our group chose to implement a secure form of storage for sensitive information such as passwords or identification numbers. This is modeled after Shamirs secret sharing algorithm. It allows us to distribute information regarding the secret key among […]
Research shows catastrophic invertebrate extinction in Hawai’i and globally
Posted on: 10 Aug 2015
Hawai’i has been called the “extinction capital of the world.” But, with the exception of the islands’ birds, there has until now been no accurate assessment of the true level of this catastrophic loss. Invertebrates (insects, snails, spiders, etc.) constitute the vast majority of the species that make up Hawai’i’s formerly spectacularly diverse and unique biota
