INTRODUCTION All modern engineering system include certain aspects of control systems at some point in their broadcast sense, control engineering and the associated theory are concerned with the means by which systems may be made to behave an a desired way. 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 equipme […]

A battery charger is an electrical device employed for charging batteries. These batteries that are usually charged by battery charger are the storage batteries also known as “accumulator” the battery charger changes. The alternating current forms the power line into d.c suitable for charging. When the battery is fully changed, is up to it’s maximum, 12 volt, the charger with automatically cut-off with the help of the contact relay […]

Battery or bird cages are homes for domesticated birds. Birds require a house in which they can fly and have some freedom but still ensure they do not fly away. Bird cages are constructed to be large enough to accommodate the motion and daily activities of domesticated birds. This work was carried out to build a bird cage using available materials.

Car battery level monitor indicates the status of the battery just by glowing LED’s. This work explains you how to design battery level indicator. You can use this circuit to check car battery or inverter. So by using this circuit, we can increase the lifetime of battery. The heart of this battery level indicator circuit is LM3914 IC. This IC takes input analog voltage and drives 10 LED’s linearly according to the input analog voltage. […]

Electronic Components require direct current (dc) for their effective operation. This direct current can be gotten either by rectifying an alternating current (ac) or Connecting the system to a direct current source which is usually a battery. It is observed that after some period of operation, the batteries no longer function as expected. This may be as a result of degradation or discharge of the battery. This phenomenon has resulted […]
