All modern engineering system includes certain aspects of control system at some point in their broadcast scenes, control engineering and the associated theory are concerned with the means of making system to behave in a desired may. The system on this thesis is a DC – AC inverter which is an apparatus used in the conversion of direct current ... Continue Reading
This project report is a thesis written specifically to cover the design analysis construction, test and packaging of a multipurpose security system from electric component that can be easily be obtainable from the market. Continue Reading
The automatic change over switch makes use of protective relays and contractors among other things which constantly monitor the power system to ensure maximum continuity of the electrical service with minimum damage to life and property. Continue Reading
In the world today, we are being challenged with the lag of energy that used to generate the electrical power, as the solution the exploration and development of alternative power become a global issue. Some of the alternative power such as solar energy produces the direct current (DC) from the solar panel. Most of the electrical appliances today u... Continue Reading
This project as the name implies is chosen, designed and constructed with the intention of transmitting information such as musicals news entertainments programs and so on. 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 exactly t... 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
The design and construction of an Automatic Alarm System to monitor the water level is an electronic device which attempt to monitor the flood level/water level and to alert the user to put it off. Being an electronic device, it is Automatic and highly sensitive to water. Continue Reading
The general objective of the system is to provide efficiency in the use of power suppliances by ensuring continuous availability of power supply in the absence of NEPA. Uninterruptability of the system made it possible to eliminate all suspense arising from NEPA outage during the execution of an important and urgent assignment requiring Continue Reading
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 deals on the design and construction of an intruder detector for home and office use. Security as one of the biggest issues in our world today and we need a system that will be able to monitor our home, offices and industries by using two sensing circuits, touch and motion sensors. These sensors will cheek for an intruder in two differ... Continue Reading
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
The topic of this project is “ Audio Amplifier”. The research embarked upon this study or project by using both primary and secondary source of data. Continue Reading
This uninterruptible power supplies device has the capability of converting from 12volts D.C to 220volts alternating current at the frequency of 50Hz with the help of a step-up transformer. The main importance of this device is its ability to ensure absolute continuity of power to the computerized control system thereby protecting a critical equipm... Continue Reading
This is the design and construction of an Automatic Phase Selector. In the construction work, LM324 integrated circuit (comparator) and 2N2222 transistors were used as active components alongside other passive components. The circuit components were mounted on a Vero board. Result shows that, when the three phase A.C inputs: Red phase (P1), yellow ... Continue Reading
The design of this 30 volt Audio Amplifier with volume, table and bass control which was done wit ht he combination of five (5) different circuit which are interconnected during or after construction. This amplifier operates with an option of a left and right channel. The combination of these circuit include this main amplifier circuit (which co... Continue Reading
