INTRODUCTION 1.1 BACKGROUND OF THE STUDY A mobile phone jammer or signal blocker is an instrument used to prevent cellular phones from receiving signals from base stations. The process of blocking the receiver to receive a transmitted signal is called Jamming of the signal. The jammer effectively disallows cellular phone signal when activated. These devices can be used in practically any location, but are found primarily in places wher […]

This project work deals on the design and construction of an IR based remote control for an electronic/electrical device say electric lamp with the aim of switching on/off of the lamp at discretion and from a distance. It also eliminates the inconveniences associated with manual switching of bed lamps. This electronic system is designed in two functional units; the transmitter and the receiver using IR communication wave band. The tr […]
Nowadays, people love to travel anywhere. Airports mainly never run out of bustling crowds of traveler. They are carrying heavy luggage which is one of the biggest travel hassle. It is indispensable that airports offer luggage carts to ease such burden. Theses luggage carts are largely found in airports, large bus stations, hotels, or train stations. However, extra effort is required to navigate especially those individual with disabil […]
ABSTRACT This work is on sequential device control using TV remote control. This device lets one to switch ON and switch OFF up to nine devices sequentially from your TV remote control. The circuit consists of an IR sensor module TSOP1738, which is equivalent to TSOP1238. The output of TSOP1738 is fed to the trigger input (pin 2) of IC NE555 (IC1) via LED1. IC1 is wired in monostable mode and its output is fed to clock input of IC CD […]
ABSTRACT The work is on design and construction of a remote controlled fan regulator. Remote controlled fan regulator is an electronics device that enables the user to operate a fan regulator from approximately 10 meters away. However, with this device one can change the speed of the fan from your couch or bed. The device would allow a person to control the speed of a fan by simply pointing the remote towards a sensor and then pressin […]
ABSTRACT This project work deals on the design and construction of an Rf based remote control for an electronic/electrical device say electric lamp with the aim of switching on/off of the lamp at discretion and from a distance. It also eliminates the inconveniences associated with manual switching of bed lamps. This electronic system is designed in two functional units; the transmitter and the receiver using radio frequency (RF) comm […]
ABSTRACT This work is on a remote control motor car. Remote controlled car is battery/ powered model cars or trucks that can be controlled from a distance using a specialized transmitter or remote. This Radio controlled system is adopted in many vehicles like cars, boats, planes, and even helicopters and scale railway locomotives. In this work we will use a couple of ICs and a motor fixed to a chassis to make a remote control car. Thi […]
