High power amplifier are usually quite costly and usually beyond the easy reach of most audio enthusiastic (and Hi-Fi buffs) who then have to remain satisfied with those small 6 watt amplifiers. Well, with this introduction to us and to electronics, things should change. Well this low cost Hi-Fi amplifier that delivers ear chatting and thundering ... Continue Reading
This project work-up deals on the design and construction of a single phase step down nations fermor, with raking IKVA, 240V/11OV, 80V 12U, 6V. It is a multi-circuit transformer that has one input as the primary and tappins to produce the output (secondary). It is considered as a single coil in series with the supply and a common coil to the head. ... Continue Reading
The intruder alarm system was designed and build in order to let the industrial and commercial company know how important alarm system is all about. These can be of Good help if the intruder will look through this project and support for the development of this project as to let the Federal Government know that the young engineering of today can pr...

An audio AMP is basically a system which is used as a means of increasing the level of sound or audio signals for maximum use. A public address system consists basically of microphone, Amplifier and speaker(s) to facilitate the communication to intelligible speech to groups of people or an audience. The main purpose of providing sound reinforcem... Continue Reading
In the world today, the use of power supply in electronics equipment and gadgets has increased and it is still increasing. These power supplies are not stable as required by these electronics. This arise the need for the power stabilization as to overcome this problem Continue Reading
The uninterruptible power supply (UPS) is design to help in the offices, workshops and house hold appliances, due to the unstable power supply being supplied by (NEPA) presently known as Power Holding Company of Nigeria (PHCN) usually supply to us. Continue Reading
This project involves the construction of 4600mAh power bank, it consists of three different modules which are; power storage module, battery charging module and phone charging module. All these modules consist of different circuit in other to perform their main functions.rnrnThe power storage module consist of pen batteries of 1.2V with 46... Continue Reading
The early transmitter for radio broadcasting is so big and bulky that they do occupy numerous spaces. The circuitries are mainly designed with valves, which are big in sizes. With the advent of semiconductor materials such as transistors electronic equipment are now becoming miniaturized such that small transmitters are now becoming handy and com... Continue Reading
This project is about the design and construction of 2KW 230 volts solar panel inverter at a frequency of 50Hz. The device is constructed with locally sourced components and materials of regulated standard. The basic principle of its operation is a simple conversion of 12V DC from a battery using integrated circuits and semiconductors at a frequen... Continue Reading
The aim of this project is to construct power amplifier. The system is expected to amplify. The major components in the circuit is the integrated circuit (IC JRE with some circuit elements for the normal operation of the circuit. Continue Reading
The project work is on the design and construction of automatic two lane traffic light control. This system is based on digital electronics. It employs an astable multivibrator which is the clock generator that sends the clock into a time sequencing generator using a decade counter with ten (10) decodes output that has it’s binary corded decim...
