As the world is developing the need for electronics in human endeavor is now taking a larger scope. With the invention of certain electronics gadgets in our societies today, certain activities become easily handled for example; in communication where the telephone plays a part. In places where safety are needed an alarm system will be of much impo... Continue Reading
The purpose of this text is to present at a primary and intermediate level a comprehensive over view of the construction principle and indeed the operation of a Digital Incubator. We want to present a situation where by as the temperature in going up let the resistance be decreasing and as the temperature decreases let the resistance be going up. 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
The machine is designed to serve with an output of 250A. it has two pats which are the primary and secondary parts. The primary part, through which voltage is supplied to the machine has 180 turns which is made of 2mm2 S.W.G 14 copper coil. The secondary part has 45 turns made of 4mm2 S.W.G 8 copper coil. 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 and the input which serve as a transformer which the f...

Due to inconsistent supply of power, there is a growing need for an alternative source of power supply. This has lead to heavy capital investment in a bid to suppress power failure and ensure regular power supply for the industry, hospitals, schools and homes. The problem of power failure can be checkmated with the use of stand-by generating set. 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
This project is he design and construction of a voltage inverter system with trickle charging system. This device is design to provide power supply for the need of offices, household etc. In absence of NEPA power supply. It would also prevent harm to our appliances caused by power holding company LTD (NEPA) Random power outage . Continue Reading
The system on this thesis is a DC – AC converter, which is an apparatus which is used for conversion of Direct Current to Alternating Current or signal. In our country, this equipment is not all that in used not because it is not important but because people never give it a thought as per the construction and design. Continue Reading
The topic of this project is �“ Audio Amplifierâ€Â�. The research embarked upon this study or project by using both primary and secondary source of data. 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
Sequel to the vast need and use of iron rods, metal bars and pipes, right from the domestic level up to industrial extent, the arc welding machine was built in order to ensure that the ulterior motive of the manufacturers of these products (iron rods, metal bars and pipes) by their manufacturers is being achieved as part f technological advancement...
