Ionizing radiation is something that almost anyone finds exciting (or scary) and I’ve also been for long wanted to build a Geiger counter. Unfortunately Geiger tubes have usually been too expensive to seriously consider buying them just for a hobby project. But I found out that sovtube sold soviet cold war era Geiger tubes only […]

INTRODUCTION As technology develops, computers are making people’s lives progressively easier and safer. Someday they will be able to drive automobiles, resulting in reduced deaths and accidents. We decided to make a prototype of a self controlled car. We started with a Hot Shot II radio control car and stripped out the radio receiver. Then […]

A Florida-based marine research team has developed a unique formal process and modeling framework to help manage South Florida’s economically important coastal marine environments. The MARES project (Marine and Estuarine Goal Setting), led by the National Oceanic and Atmospheric Administration’s (NOAA) Cooperative Institute for Marine and Atmospheric Studies (CIMAS) based at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, successfully integrated both ecosystem science and societal benefits into a marine ecosystem support tool to help improve decision-making by natural resource managers.

(Phys.org) —Long hours of nighttime driving can cause eyestrain because while our vision adapts to the surrounding darkness, the sudden stabs of brightness from streetlamps can be irritating, distracting and even painful. Even as LED technology has transformed the lighting industry, bringing the promise of more energy-efficient road illumination, some fear that the new lights could cause even more troublesome, unsafe glare.

Introduction The goal of this project is to design an algorithm for a real-time digital guitar tuner and implement it using an Atmel AT90S8535 microcontroller. Each of the six strings of a guitar has a unique fundamental frequency, and our goal is to measure this frequency and compare it to the correct frequency. This project […]

Introduction Nowadays many of the most “exiting” chips come only in leadless packages, such as BGA and QFN which are hard or impossible to solder just by soldering iron, because leads are under the chip where they can’t be reached. These kinds of chips are usually soldered using reflow soldering. In reflow process solder paste […]

Introduction: Our final project code calls for the implementation of an amusement game often bannered as “Test-Your-Strength” or less accurately (but more commonly) known as “Whack-a-Mole.” Our machine is in essence a miniturized version of what can be found in most theme parks across the world. Its construction involves a spring load plastic cap to […]

Introduction: One of the newest and fastest growing additions to the digital age in the 1990s has been the handheld personal computer. Given a little flash memory and a good LCD, anything is possible and commercial products like the 3Com PalmPilot� and IBM Workpad� are flourishing. But as these products expand their functionality so does […]

Introduction For our final project, we set out to write a Controller for the classic toy, the Etch-A-Sketch. What this basically means, is that we use an Atmel micro controller to control two stepper motors connected to the knobs of the Etch-A-Sketch. Thus, an order by the chip to the motors would cause different angled […]

Description A single AVR microcontroller (the ATmega 1284P) has been used to create a standalone computer system which runs the BASIC programming language. The 1284P runs TinyBASIC Plus, generates composite video signals (using TVout) and reads PS/2 keyboard input. A single sided PCB was used to hold all the components meaning it is easy to […]
