A battery charger is an electrical device employed for charging batteries. This batteries that are usually charged by battery changer are the storage battery charger are the storage batteries also known as “accumulator” the battery changer changes. The alternating current form the power line into d.c suitable… Continue Reading
The main objective of this project was to ensure a proper security to car being parked in garage against theft or an intruder. The circuit uses three NE555 timers; one of the NE555 was wired as a monostable oscillator and remaining two were wired as tone generator and amplified to obtain a maximum audible sound. However, pin 2 of the… Continue Reading
This project is design and construction of a sound detector with alarm system was done primarily to detector sound. It can be use in industrial and domestics. It employ four discreet stages with power supply which power the system. The 1st block is pick up amplifier containing the microphone… Continue Reading
This research work examines the factors affecting power outage in Nigeria. Constants Power supply is the hallmark of a develop economy. Any nation whose energy need is epileptic in supply prolongs her development and risk-losing potential investors. Nigeria with population of over 120 million people has for the past 40 years of… Continue Reading
Automatic water level controller for both overhead and underground tank is designed to monitor the level of water in a tank. It displays the level of water and when it is at the lowest level; a pump is activated automatically to refill the tank. When the tank is filled to its maximum capacity, the pump is automatically de-energized.… Continue Reading

And all these that are written above are being transmitted to the atmosphere using an electromagnetic, signal, and this particular project design and construction is… Continue Reading
The practical importance of a battery charging unit in today’s world cannot be over emphasized. This is so since these batteries or accumulators are immensely needed by automobiles and in science laboratories. This thesis describes the methodical approach to the design and construction of any battery changer. However the procedure… 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 This project handles this problem very well. Some recommendations were… Continue Reading
This project is titled the design and construction of a DC to AC inverter system. It is designed to meet up with the power demand in the offices and in homes in the absence of power supply from the national supply authority, NEPA. In order words the device / item serves as a substitute for NEPA which almost monopolises the power supply to… 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. With the help of the “UPS” we don’t need to depend much on PHCN it is stress free… Continue Reading
This project work is on the construction of an F.M transmitter this system consists of four discrete modules namely the audio frequency (AF) amplifier (class A) the modulator the master oscillator and the radio frequency (RF) amplifier (ClassC) these formed the conventional events for building FM transmitter here the signal (from the… Continue Reading
