ACKNOWLEDGMENT
1
I have taken efforts in this project. However, it would not have
been possible without the kind support and help of many
individuals and organizations. I would like to extend my sincere
thanks to all of them.
I am highly indebted to Mr. N. C. Purohit for their guidance and
constant supervision as well as for providing necessary information
regarding the project & also for their support in completing the
project.
I would like to express my gratitude towards my parents & friends
for their kind co-operation and encouragement which help me in
completion of this project.
My thanks and appreciations also go to my colleague in developing
the project and people who have willingly helped me out with their
abilities.

INTRODCTI ON
Almost every entertainment gadgets at home, be it a TV, DVD
Player, Music System uses Infra Red Remote control. These
remote uses Infra Red Light for communication with the TV
device. Whatever the type of remote it uses batteries to power to
an Infra Rea LED, controlled by an electronic circuit that beams a
code sequence corresponding to the key that we press.
Unlike most other electronic gadgets an infra red remote has no on
off switches .the remote is always in on state, consuming very little
power when in a dormant state when a button is pressed goes into
an active state, transmit the control code and then goes into
dormant state again.
This project shows how to retro fit your regular remote control
device for battery free operation forever. This idea is not so much
is so on recurring batteries costs, but to remove batteries from the
system altogether.

PRINCIPLE The voltage required by the remote control device is generated
using a DIY kinetic generator (shown above) that converts
mechanical power to electrical power, based on Faraday’s
principle. The device consists of a hollow tube of plastic or wood,
with a cylindrical magnet sealed inside the tube, and 1,400 turns of
enameled copper wire wound around the outer surface of the tube.
When the tube is shaken, the magnet travels the length of the tube
back and forth. This leads to a change of magnetic field as seen by
the wire, and generates an EMF (electromagnetic force) that is
proportional to the number of turns and the rate at which the
magnetic field is changed. Thus, if you shake vigorously rather
than gently, a larger EMF is generated. You can use this principle
to easily generate operating voltage for any infrared remote control
device.

CIRCUIT DESCRIPTION
This circuit consist of four main parts:-
1. Infrared remote control device
2. Faraday voltage generator
3. Charge storage component
4. Voltage regulator
Shown here is the schematic of the Faraday voltage generator, the
charge storage capacitor (capacitor C1 consisting of two
4700μF/16V capacitors in parallel), and the voltage regulator
circuit based on a low dropout (LDO) regulator.

MATERIALS

Main component used in this project are as follow:-
[A] Enameled copper wire, 30 or 36 gauge:- Enough to roll
about 1,400 turns of wire. The gauge of the wire is not critical. We
used 36 gauge, but any other, preferably smaller gauge (larger
diameter), can also be us.
[B] Voltage regulator LP2950-3.3 (1):- This is a 3.3V output, low
dropout voltage regulator. The LP2950 is a micro power voltage
regulators with very low quiescent current (75μA typ.) and very
low dropout voltage (type 40mV at light loads and 380mV at
100mA).They are ideally suited for use in battery-powered
systems. Furthermore, the quiescent current of the LP2950
increases only slightly in dropout, prolonging battery life.
This device excellent choice for use in battery powered application
such as cordless telephone, radio control systems, and portable
computers.
FEATURES
● High accuracy output voltage
