ABSTRACT
Generally, to extract any raw materials from mines, the workers have to go to deeper
layers into the earth. To provide electricity (A.C) in such locations has created problems like
electrical lines by using dynamo operated by hand crank.
The dynamo is capable of delivering power to switch on the emergency head lamp. The
dynamo uses electromagnetic principles to convert mechanical rotation into a direct
current (DC). In this project we are generating electrical power as non-conventional method by
Hand crank dynamo.
In this project we are using hand crank dynamo, geared dc motor Reverse polarity
preventer cum polarity corrector, A.C ripples neutralizer, unidirectional current controller and we
use NiMH (Nickel Metal Hydrate Battery) which has high charge storing capability and long
durability. It is a Rechargeable battery with specifications as 3.6V, 600mAh.
AT89S52 micro controller is the heart of the circuit as it controls all the functions. A
voltage sampler is interfaced with the system using ADC 0808 to get the voltage generated from
hand cranked dynamo stored in battery as a display on a 16X2 LCD.
A 12 V DC lead acid rechargeable battery is used for storing the energy. We are using
conventional battery charging unit also for giving supply to the circuitry.
This Conventional power source uses regulated 5V, 500mA power supply. 7805 three
terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to
rectify the ac out put of secondary of 230/12V step down transformer.
