Brain Machine Interface Seminar Topic

Introduction to brain machine interface:

In this paper, we will see how the brain machine interface is made and how the capabilities of the human being can be extended. We will about the advantages of using brain machine interface and the problems faced by this.

The capabilities of a human being are limited and a capability of a machine is higher but it cannot think of its own. Research is going on for making a machine to interface with the brain by which the capabilities of a human being are far extended.

Brief on brain machine interface:

The human brain takes decisions based on the impulses generated in the body and in a human body we find millions of neurons which generate impulses. So a chip is designed and it is placed in the human body and it is made to integrate with the nerve fibers. The chip is interfaced with a remote computer outside.

The chip senses the impulses generated in the body and performs the tasks with the help of the remote computer or the server located outside. The chip is designed by using nano technology and it is constructed in such a way that it can generate the power required for it through heat generated in the body or by the flow of blood circulation.

The chip has successfully placed a body of professor in a university and he could control the appliances without lifting his hand from a given range.

Proposed Brain Systems in Future:

The proposed brain machine interface chip can be very helpful to make the organisms to work properly for the paralyzed patients. By using brain machine interface the human capabilities gets increased a lot and many technological advancements can be made.

But due to this there may differentiation in between the persons who are using the interface chips and the normal human being. All details about this system explained in the given ppt presentation.

Automatic Solar Panel

In our project Automatic Solar Panel we implemented an automatic sun tracking system by utilizing the services of light dependent resistor, the LDR’s position is monitored by the micro controller based on this the angular movements of the DC motor is controlled. It is an intelligent solar power generation system because it generates the energy by itself it doesn’t require any manual operation.

Renewable energy resources are rapidly gaining importance in the field of electrical power generation. We know that solar energy is the most available and popular renewable energy resource, so we need to utilize the solar energy so we implemented a system which tracks the solar energy in its semi circular cycle.

Proposed system:

The Automatic Solar Panel system is an closed loop system designed to align the solar panel toward the sun rays. Here in this project the angular position of the solar panel is controlled by the dc motor which is interfaced with the control system circuitry having micro controller setup. The LDR detects the maximum intensity of the sun light and send the signals to the micro controller then the micro controller manipulates the dc motor for rotating the solar panel towards the maximum intensity regions.

Light Depended Resistor:

The name itself depicts that the resistance value is dependent on the intensity of the light i.e. such that the resistance is low whenever the sun light intensity is high and vice versa.


The PCB fabrication is done to provide the electrical inter connections to various components in the circuit. This process involves drilling, cutting, cleaning, wiring, soldering and testing.

We observed the working of Automatic Solar Panel project practically here we placed a black cloth on the four LDR’s to provide uniform light intensity then we removed the cloth on LDR1 panel moved forward, and we removed the LDR2 the panel moved backward like that we conducted serial verification and we found that the system is successful in detecting the variations in the sun light.

Wireless Petroleum Level Indicator Project Report

Now a day’s the wireless and embedded technologies are enormously used in security managing systems. Here in this project “Wireless Petroleum Level Indicator”, we implemented an AT89S52 Microcontroller based tank level monitoring system for monitoring the fuel level in the tank and to control the thefts.

The system is comprised of Microcontroller, RF Transmitter and Receiver, limit switch for sensing the fuel level, IR Transmitter and Receiver, power detection circuit, GSM Modem, Voice Processing Unit at the receiver terminal of the control room. The systems mechanism is mainly divided into two phases one for sensing unit and the other is alert system.

Laser Communication System Project Report

Laser communication system Project Report explains about new advanced communication strategy in the field of wireless communication. Several communication technologies are developed in recent days apart from those technologies lased communication systems having enormous applications.

These are next generation communication systems which had taken origin from the fiber optic systems. By implementing these networks we can communicate to other wirelessly.

Project description:

In this project we transmit data by means of lasers instead of radio frequency signals, the laser torch acts as a carrier for the signal transmission. We used laser torches which can transmit the light up to the distance of 500 meters. This circuit had two major parts one the transmitter circuit and the other the receiver circuit.

Transmitter circuit:

The transmitter circuit consists of microphone transistor amplifier BC548, op amp μA741, and 1-mega-ohm pot meter with 9v input power supply.

Receiver section:

The receiver section comprises of NPN phototransistor for sensing the light, pre-amplifier to amplify the low amplitude signals, bypass capacitor for the prevention of loss of amplification, loudspeaker of 0.5W.
