  • Figure:1 Poster Presentation of App

    First Step Android App

    Posted Apr 30, 2014 By James Faraday
    The first step the app provides users a comfortable and anonymous route through which they can pursue self-assessment and mental health resources. It utilises the Goldberg Depression Questionnaire which was developed by Dr Ivan Goldberg, MD. The results of this questionnaire are then used to intelligently provide resources based on the weight of different answers for different questions. For…

    Emerson Oven Control System

    Posted Apr 22, 2014 By James Faraday
    To do this we made use of an Arduino micro-controller board, Labview, our own custom designed printed circuit board, a relay designed to handle 20 Amps, and a switch created using a bipolar junction transistor (BJT). Picture of our completed PCB: Picture of Ultiboard simulation of PCB: Picture of the prototype Labview user interface as well as test software: Picture…
  • Figure:3 5 Channel IR Remote Control System - Transmitter Circuit

    5-Channel IR Remote Control System

    Posted Apr 14, 2014 By Sudheer Gupta
    This article is aimed to design and demonstrate a simple 5 channel remote control system to drive five loads. The input signals or the commands are sent from a transmitter using IR transmission and received by the IR receiver, processed and used to drive the loads. Principle behind the Circuit The circuit works on the principle of IR communication. IR communication involves transmitting…

    How to Build Digital Voltmeter Circuit using ICL7107

    Posted Apr 08, 2014 By Sudheer Gupta
    A voltmeter is an instrument measuring the potential difference between two points. A typical digital voltmeter consists of a analog to digital converter and a digital display. Here we design a analog to digital converter working as a digital voltmeter using a low power three and half digit A/D converter ICL7107 having internal 7 segment decoders, display drivers, a reference and a clock. h2….

    Analog Solutions for the PAPR Problem in OFDM

    Posted Mar 26, 2014 By Kalpana Manickavasagam
    Recently, a worldwide convergence has occurred for the use of Orthogonal Frequency Division Multiplexing (OFDM) as an emerging technology for high data rates. In particular, many wireless standards (Wi-Max, IEEE802.11a, LTE, DVB) have adopted the OFDM technology as a mean to increase dramatically future wireless communications. Peak to Average Power Ratio (PAPR) has been a major problem in…
  • Figure:7 Circuit Diagram of 100 W MOSFET Power Amplifier

    MOSFET Power Amplifier Circuit Principle

    Posted Mar 20, 2014 By Sudheer Gupta
    This circuit operates on the principle of multi-stage power amplification consisting of pre amplifiers, drivers and power amplification using MOSFET. The pre amplification is done using a differential amplifier, driver stage is the differential amplifier with current mirror load and power amplification is done using MOSFET class AB operation. MOSFETs have an advantage over BJT in having a simple…

    RF Controlled Robotic Vehicle With Laser Beam Arrangement

    Posted Mar 19, 2014 By Ravi Kumar
    The project is designed to control a robotic vehicle by using a RF technology for remote operation. A low power laser light is interfaced for demonstrating the possibilities of destroying a distant object by its beam. An 8051 series of microcontroller is used for the desired operation. Note: As per government security norms, batteries would not be included in the…
  • Figure:9 Police Siren Circuit Using 555 Timer

    Police Siren Circuit Using 555 Timer

    Posted Mar 12, 2014 By Sudheer Gupta
    Here is the simple circuit designed to produce a sound similar to the police siren and is built using NE555 Timer. Two 555 timers act as an astable multivibrator. Circuit Diagram of Police Siren using 555 Timer: Police siren circuit which is explained here is worked on NE555 timer IC. The circuit is build with the help of two NE555 IC(i.e. IC1 andIC2) which is the basic block of…
