12 VOLTS AUTOMATIC BATTERY CHARGING SYSTEM

ABSTRACTThis design is aimed at providing a system that has the capability of recharging batteries after use. The design is to incorporate an auto charging cut off circuit that operates when the battery is fully charged to avoid damaging the device and also a low voltage circuit which prevents the system from damage should in case the battery voltage level drops to a particular preset value.  This design is used to charge batteries not exceeding 36volts and a lineup of batteries not exce...

A GSM BASED HOME AUTOMATION USING AVR

ABSTRACTWith advancement of technology things are becoming simpler and easier for us. Automatic systems are being preferred over manual system. The purpose of this project is to design and construct A GSM based home automation using AVR. Using GSM networks, in this project a home power control system has been proposed that will act as an embedded system which can monitor and control appliances and other devices locally using built-in input and output peripherals. The system has a delay of 2 m...

AUTOMATIC RAIN SENSING WIPER SYSTEM

ABSTRACTThe world today is moving ahead at a very fast pace. Some of the very common examples of fast moving objects are aeroplanes, high speed cars and many more. In our everyday life we come across many fast moving vehicles and so it is very important to measure the speed of these vehicles.This is an era of automation where it is broadly defined as replacement of manual effort by mechanical power in all degrees of automation. The operation remains an essential part of the system although wi...

BURGLAR ALARM UNIT

INTRODUCTIONAs 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 important.The application of electronics in this modern age is simply inexhaustible and this group form more interest in the alarm sys...

CONSTRUCTION OF 500W12VINVERTER CHARGER

ABSTRACT An inverter is a system which is capable of converting DC voltage from a battery into AC voltage. The Inverter constructed converts 12V dc to 220V Ac. It consists of an oscillator section using 8V dc to produce 50Hz sine wave. The sine wave is amplified by Tip 41 and used to drive IRPF 250 MOSFET power transistors capable of delivering 500W norminally.The mosfet switches the 12V dc across the high current transformer which then produces the Ac at its output. The output of the tr...

CONSTRUCTION OF A BLENDER

ABSTRACTBlender is an electric machine for size reducing soft food or liquid mixture.  Blender is some time called liquidizer consists of a glass jar or jug containing a steel blade assembly at the base driven by a small electric motor.Construction of blender was done based on the principle of size of reduction using electric motor as the major driver force.  During the construction of blender, we adopted different stages which includes:The production of preliminary drawings with de...
