This page contains project topics/write-up for ELECTRICAL/ELECTRONIC/TELECOM/ POWER ENGINEERING department. Hyclassproject's aim of providing all these research materials is to reduce the stress of moving from one school library to another all in the name of searching for project topics and materials. We are not encouraging any form of PLAGIARISM. This service is legal because, all institutions permit their students to read previous projects, books, articles or papers while developing their own works. According to Austin Kleon "All creative work builds on what came before", and according to Bishop Dr. David Oyedepo "You cannot be a Reference without having References".

Below are the list of our avaliable project topics/write-up, to view or download the complete work on each of the following works, click on the useful links menu at the right-hand or bottom part of this page:

0001]. DESIGN AND CONSTRUCTION OF TEMPERATURE CONTROL AUTOMATIC SWITCH : This project is titled design and construction of a temperature control automatic switch. It is designed to control electric appliances such as electric kettle, oven, incubator, or lamp through the variation  of temperature range (0°C -100°C) which must be set by the user or operator. And this can be achieved by the use of temperature sensor known as THERMISTOR. This thermistor is a temperature control device with a high or low resistance value which can go high or low when the temperature is increased or reduced depending on the type.
 In this project, 100C is used as a set temperature. And this device is design in such a way that when the set temperature of the device is reached, the relay of the device will automatically triggered and will maintain this stage until when the temperature of the sensor is dropped 97°C, and then it will return normally open stage in order to maintain that 100°C. And this automatic feature is controlled by a high current relay....{read more and download full material}
0002]. DESIGN AND CONSTRUCTION OF AN OSCILLATING STAGE OF A 3.5KVA INVERTER : An oscillator is an electronic device that converts dc power supply to ac power having the desired characteristics.
Power inverters come in a wide variety of power capacities and they are distinguished primarily by the wave shape (sine or cosine, square and others as shown in the figure 2) of the alternating current they produced from the oscillator employed for the design. The major types are: 1. Pure sine-wave inverter, 2. Square wave inverter, and 3. Modified sine-wave inverter. The basis of the oscillation in an electric circuit is the positive feedback.
Oscillator falls into the following classes; Positive feedback (RC and LC networks), Negative resistance, and Relaxation type. The discussion of the oscillators in this paper will be focused on the low frequency oscillators that can be employed for the design of power inverters operating at 50/60Hz....{read more and download full material}
0003]. FOOT STEP POWER GENERATION USING PIEZOELECTRIC SENSOR:This work is on foot step power generation using piezoelectric sensor. In this foot step power generation project is designed to convert foot step, walking and running energy into electrical energy. It is used to generate electricity from by walking or running on foot step. The demand of electrical energy is increasing day by day. But power generation conventional resources are now not enough for total demand of electrical energy. Therefore many researchers and engineers are working on non conventional ways of electrical power generation. Foot step power generation system is also a non conventional electrical energy production system. It converts mechanical energy of foot steps into electrical energy by using transducers. It can be implemented on roads, bus stations and many public places. Foot step power generation system basically converts force energy of foot into electrical energy by using piezoelectric sensor. Piezoelectric sensor is transducer which converts force energy into electrical energy....{read more and download full material}

0004]. DESIGN AND CONSTRUCTION OF SMART STREET LIGHTING SYSTEM USING ULTRASONIC SENSOR : Generally, street lights are switched ON for whole night and during the day, they are switched off. But during the night time, street lights are not necessary if there is no traffic. Saving of this energy is very important factor these days as energy resources are getting reduced day by day. Alternatives for natural resources are very less and our next generations may face lot of problems because of lack of these natural resources. Smart street lighting system works automatically to regulate light intensity, the operating time and detect objects....{read more and download full material}

0005]. DESIGN AND CONSTRUCTION OF A BLUETOOTH SPEAKER UNIT: Bluetooth stereo audio system—one that’s also fairly low-cost—for outdoor use. This device provide the easiest way to play music off your smartphone to a speaker unit. The system, which maintains 20-WRMS output power, can be controlled either with a handset containing a Bluetooth connection and a music player or with an Apple iPod model. Bluetooth technology, created in the late 1990s, is widely used to establish a short-range wireless connection between two handheld mobile devices. A Bluetooth setup also makes it possible to transfer a stereo audio signal from a handheld device to a speaker unit . Today’s Bluetooth headsets operate under the Bluetooth Class 2 specification with 2.5-mW (4 dBm) transmission power. A Bluetooth Class 2 module’s transmission range extends to about 10 meters....{read more and to download full material}

0006]. DESIGN AND CONSTRUCTION OF A 12 VOLTS AUTHOMATIC BATTERY CHARGER WITH BATTERY FULL CUT-OFF AND DIGITAL DISPLAY : This project is on a 12 volts automatic battery charger with charging progress   and charging level indicator. An automatic battery charger is an acid battery charger that is designed to charge any acid battery.
In this work, a voltage sensor circuit is incorporated to sense the voltage of the battery under charge. The charger has the ability to automatically switched OFF when the battery voltage reaches the required optimum level with the help of the relay relay, the transistor and the zener diode when bend the current back to the system, and the system have the ability to indicate when the battery is charging or not, when the battery is empty or fully charged through the digital display....{read more and download full material}

0007]. DESIGN AND CONSTRUCTION OF A 1KM TRANSMITTER: An FM transmitter is an electronic device which, with the aid of an antenna, produces radio waves. The transmitter itself generates a radio frequency alternating current, which is applied to the antenna. When excited by this alternating current, the antenna radiates radio waves.
FM transmitter is basically a VHF colipits oscillator capable of transmitting sound or music to any standard FM receiver. The circuit works on a D.C source which makes it for a pure rectification. FM transmitter also has a capacitor microphone which picks up very weak sound signals.
The FM transmitter was designed using transistors and other component such resistor, inductor and capacitors. This project transmits frequency on 100MHz± 5%. The transmitting distance is l00metres. It is powered with 5volt – 15volts D.C battery using suitable F.M receiver tuned to the transmitting frequency of this project. F.M Transmitter can be used as cordless microphones, mobile phone and for public address purposes. The distant of transmission is limited to 100m and fixed frequency of transmission, away from all other radio station. This gives best range and least interference....{read more and download full material}

0008]. DESIGN AND CONSTRUCTION OF AN FM TRANSMITTER:An FM transmitter is an electronic device which, with the aid of an antenna, produces radio waves. The transmitter itself generates a radio frequency alternating current, which is applied to the antenna. When excited by this alternating current, the antenna radiates radio waves. Frequency modulation (FM) transmitter generates the radio waves by varying the radio signal’s frequency slightly. FM transmitter is basically a VHF colipits oscillator capable of transmitting sound or music to any standard FM receiver. The circuit works on a D.C source which makes it for a pure rectification. FM transmitter also has a capacitor microphone which picks up very weak sound signals. This FM transmitter was designed using transistors and other component such resistor, inductor and capacitors. This project transmits frequency on 100MHz± 5%. The transmitting distance is l00metres.
