Summary Our ECE476 Final Project is a digital pre-amplifier. A digital pre-amplifier basically takes an analog music signal, converts it digitally, and spits it out as a new, modified, analog signal. Our decision to do this project was sparked by our interest in music and electronic equipment. High-end receivers and amplifiers often use this analog […]

Introduction For our 2003 ECE476 Design Project, we designed a Tetris game that was playable via a 16 button keypad and was displayed on a black and white television at a resolution of 128×100. The heart of the hardware system consists of the ATMEL Mega32 microcontroller and an STK500 test board. The game mimics what […]

With more than 40 years of supply history, Texas Instruments is the premier volume supplier of voltage references. TI’s broad portfolio features low temperature coefficient, precise initial accuracy, low noise, and excellent long term stability performance. Series and shunt references support a wide variety of applications, including high-precision references for data converters up to 20-bit […]

(Phys.org) —A team of researchers with members from Rutgers University and Los Alamos National Laboratory has found a way to get around the problem of metals forming high-resistance when deposited on 2H phase molybdenum disulphide (MoS2). In their paper published in the journal Nature Materials, the team describes how they came up with a process for inducing 2H phase nanosheets to the metallic 1T phase, thereby reducing contact resistance.

News April 27, 2003 The project is due for us tomorrow, since we have the Monday evening lab slot. We spent a little time in the lab fixing the last few bugs, tweaking a little, and taking some pictures. We have an enclosure for the hardware so it’s not just a bare circuit board with […]

Kepler is the best intelligent gas and carbon monoxide (CO) detector. Packed with powerful sensors, Kepler constantly monitors gas and CO levels in your home, giving you peace of mind knowing your home and family are safe Protect your Home from Dangerous Gas Leaks   From ovens to furnaces,water heaters to dryers, most of us […]

A 4-bit gray-scale video system demonstrated by a multiplayer game Our project displays a 128-by-96-pixel image in 4-bit gray-scale (16 intensities) by using a memory-map compression scheme. The equivalent uncompressed display would require 6-KB of memory (128 � 96 pixels � 4 bits/pixel = 6,144 bytes), but we manage to achieve this in less than […]

Desoldering braid makes an invaluable service at development or rework. Everyone who´s ever tried to suck off a solder from a solder pad by means of a solder absorbing braid (wick) will probably confirm, that this tool belongs to a “must have” equipment of every professional or amateur workplace. What´s the charm of a desoldering […]

INTRODUCTION Hello there!  We developed a game to play Connect 4 (for either one or two players) hooked up through a TV’s video input, using only a simple keypad.  The premise of the game is simple: drop your pieces so you get four in a row in either the horizontal, vertical, or diagonal directions.  For […]

Description Water Level Alarm is a simple project to detect and alarm once the water level in tank or Aquarium reaches at certain level. Circuit is based on popular NPN transistor BC547 which act as switch, Sensor also made on PCB, when the water reaches the sensor PCB, base of transistor connected to positive supply, […]
