The design of paper cutting machine using Geneva mechanism is very useful to cut papers in equal and accurate dimensions. Geneva drive is an indexing mechanism that converts the continuous motion into intermittent motion. Due to the intermittent motion, the paper is moved between the time intervals of cutting periods. Then the paper cutting is achieved by the crank and lever mechanism. The cutter will be back to its original position by the spring effect.
This machine is also used to cut the various kind of paper products, plastic, thin film, leather, slice of nonferrous metal etc. This system can be applicable in paper cutting industry and proves how it can be a low cost solution in the production practice.

As the basic law of Physics says Energy can neither be created nor be destroyed, it can only be converted from one form to another. During huge amount of energy is lost t atmosphere as heat. It will be good if we could store this energy somehow which is otherwise getting wasted out and reuse it next time we started to accelerate. Regenerative braking refers to a system in which the kinetic energy of the vehicle is stored temporarily, as an accumulative energy, during deceleration, and is reused as kinetic energy during acceleration or running. Regenerative braking is a small, yet very important, step toward our eventual independence from fossil fuels. These kinds of brakes allow batteries to be used for longer periods of time without the need to be plugged into an external charger. These types of brakes also extend the driving range of fully electric vehicles. Regenerative braking is a way to extend range of the electric vehicles. In many hybrid vehicles cases, this system is also applied in hybrid vehicles to improve fuel economy.

The actual working of hydraulic system that lifts the car takes place by single press of the button provided on dashboard. When the switch is turned on the motor starts running which is powered by a battery already available in the car. This motor facilitates the flow of oil which is pressurized by the pump provided. This pressurized oil id then directed to the control unit which in turn directs the flow. Distribution of the pressurized oil is controlled by a switch on the dashboard. As the oil proceeds into the hydraulic cylinder, it exerts a certain amount of pressure on the plunger or the ram inside the cylinder. This exerted pressure of the oil is converted into a linear force which in turn causes the plunger in the cylinder to move out of the cylinder. Thus ultimately the exerted pressure of the oil is converted into linear motion of the plunger. As the plunger downwards out of the cylinder linearly, after a definite travel of the plunger in the downward direction and once it touches the ground it starts lifting the car.
Once the car is lifted to a desired height the tires can be changed. It is the specialty of a simple hydraulic jack that it possesses a self-locking system i.e. once the car is lifted to a certain height and even if the power to the jack is cut off the jack can still hold the entire part of car that is lifted by it. And thus, the driver can easily change the tire.
Once the tire is changed, now the concern is to release the pressure in the jack which is in the form of pressurized oil. Thus a relief valve is provided on the jack for this purpose. But since it is impossible to actuate this valve manually when this jack is installed on the chassis, this valve is then provided on the dashboard of the car in form of a switch which controls the relief valve provided on the control unit of the system. Once the relief valve is opened the oil in the cylinder which has lost its pressure energy, starts returning to the control unit. Once the oil starts returning the control unit then sends the accumulated oil back to the oil sump. And in this way the entire system efficiently works.

The main function of the steering system is to connect the rotary motion of the steering wheel in to angular displacement of the front wheel. But if only the front wheels are steered then it takes turning of the vehicle having the centre of radius at the centre of the pair of the rear wheels. This becomes very difficult to steer the vehicle when there is deficiency of the available space. Also to overtake the front vehicle at high speed, if there is four wheel steering then it takes very little time. The four wheel steering arrangement is best suitable when there is very less space in between the two parked vehicle of the order of nearly equal to the size of the vehicle and we required to park the vehicle then using four wheel steering we can do the task in the available space suitably, hence we thought of manufacturing such a system of mechanism which will steer the automobile easily. Also the steering system must also maintain the straight-based motion of the vehicle while it encounters pot holes and road bumps and must operate with minimum effort.

Collisions can happen during reversing or parking the car especially in the limited space. Since many drivers acknowledge that parallel parking is a very tedious task. This research aims to develop the parallel parking system by developing small mobile vehicle as a model. Design of prototype vehicle is considered for the real-life parallel parking. Hence, it can detect a parking space, execute the parking maneuver, avoid hitting the front, rear obstacles and reduce the time for parking. The parking maneuver is simplified by choosing the optimum turning angle for both the first and second parts of the parking maneuvers. At the first stage, ultrasonic sensors sense the parking environment and if the space is sufficient, a safe parking maneuver is generated. In second stage, positioning phase, the mobile vehicle will execute reverse motion into the parking space without any collisions. The last stage, it moves to the correct parking position in the parking space while adjusting itself to a safe distance from front and rear obstacles respectively. It is discovered from the result that developed system required just 1.33 times longer parking space than vehicle overall length. Small mobile vehicles successfully able to manage the parallel park itself without hitting or touching front and rear obstacles. The main function of the steering system is to connect the rotary motion of the steering wheel in to angular displacement of the front wheel. But if only the front wheels are steered then it takes turning of the vehicle having the centre of radius at the centre of the pair of the rear wheels. This becomes very difficult to steer the vehicle when there is deficiency of the available space. Also to overtake the front vehicle at high speed, if there is four wheel steering then it takes very little time. The four wheel steering arrangement is best suitable when there is very less space in between the two parked vehicle of the order of nearly equal to the size of the vehicle and we required to park the vehicle then using four wheel steering we can do the task in the available space suitably, hence we thought of manufacturing such a system of mechanism which will steer the automobile easily. Also the steering system must also maintain the straight-based motion of the vehicle while it encounters pot holes and road bumps and must operate with minimum effort. Steering (or all wheel steering) is a system employed by some vehicles to increase vehicle stability while maneuvering at high speed, or to decrease turning radius at low speed

Fabrication of pedal operated water pump in this paper, design and construct pedal operated water pump which used in small irrigation and garden irrigation. The pedal operated pump can be construct using local material and skill. A water system includes a Centrifugal pump operated by pedal power. The pump stand includes a housing in which a foot pedal and a drive shaft rotate. It works on the principle of compression and sudden release of a tube by creating negative pressure in the tube and this vacuum created draws water from the sump. This bicycle pedal operated pumps water at 2-3 gallons per minute from wells and boreholes up to 23 in feet depth. Provides irrigation and drinking water where electricity is not available. They can be built using locally available materials and can be easily adapted to suit the needs of local people. They free the user from rising energy costs, can be used anywhere, produce no pollution and provide healthy exercise.
Construction: Rotary Vane vacuum pumps and compressors have certain significant advantages. In addition to providing smooth, pulse-free air flow without receiver tanks, they are compact (or equivalently offer high flow capacities for a given size), are simple and economical to install and operate, have low starting and running torque requirements, produce minimal noise or vibrations, are capable of long, service-free life, and are easily serviced.
Working of Project: Pumping action is produced by a series of sliding, flat vanes as they rotate in a cylindrical housing. As the diagram shows, an eccentrically mounted rotor turns and the individual vanes slide in and out of their slots by centrifugal and pressure-loading forces. This creates a series of air compartments of unequal volume against the wall of the housing. These compartments get larger during the suction part of the cycle, creating vacuum at the intake port and smaller during the discharge portion of the cycle, creating pressure at the exhaust port.

The Air vehicle is a vehicle currently being developed, and eventually, manufactured by Motor Development International (MDI). It was invented by Guy Negre, a French engineer, in 1991 started Motor Development International (MDI) Luxembourg. He invented a dual-energy engine running on both compressed air as on regular fuel, then managed to create a compressed air only-engine, and improved his design to make it more powerful in the 15 years.
The air car is powered by air engine. It is an emission free piston engine using compressed air as the fuel. The air vehicle is powered by an air engine, specifically tailored for the vehicle. The used air engine is being manufactured by CQFD Air solution, a company closely linked to MDI. The engine is powered by compressed air, stored in a glass or carbon-fibre tank at 4500 psi. The engine has injection similar to normal engines, but uses special crankshafts and pistons, which remain at top dead centre for about 70% of the engine's cycle, this allows more power to be developed in the engine. Though some consider the car to be pollution-free, it must be taken into account that the tanks are recharged using electric (or gasoline) compressors, resulting in some pollution, if the electricity used to operate the compressors comes from polluting power plants (such as gas-, or coal-power plants). Solar power could possibly be used to power the compressors at fuel station.

Most of the cities in developing countries are highly polluted. The main reasons are the air and noise pollution caused by transport vehicles, especially petrol-powered two and two wheelers. For example, in India there are close to 18 million petrol powered two wheelers and about 1.5 million petrol and diesel powered two and two wheelers and their population is growing at a healthy rate of about 15% per annum.
Besides being a major hazard to peoples health, these machines are guzzling huge amounts of petrol and diesel for which any country has to pay dearly in foreign exchange outflow. In fact it is a common sight in developing countries as much as in the City of London, Paris, Rome or Los Angeles, that during traffic jams in congested areas these vehicles produce tremendous pollution.
In our country also in the city Like Mumbai, due to increased pollution level we are going to design and fabricate the Ambitious project solar cycle.
Now Why Cycle? And not the Solar Motor cycle or Bike?
Because cycle is light in weight and is sufficient enough to carry two person as good as by Bike. And also the intensity of solar energy generated in such a small space will be enough to carry the weight of the cycle with the riders.

An engineer is always focused towards challenges of bringing ideas and concepts to life. Therefore, sophisticated machines and modern techniques have to be constantly developed and implemented for economical manufacturing of products. At the same time, we should take care that there has been no compromise made with quality and accuracy.
Springs isolate the driver from road imperfections by allowing the tire to move over a bump without drastically disturbing the chassis. If the chassis remains fairly steady then the tires are better able to follow road contours automatically.
While springs do an excellent job of smoothing over bumps, they will keep bouncing once started. In other words, the chassis continues swaying and the tires keep hopping long after the vehicle strikes a bump. Left uncontrolled, springs give an uncomfortable ride with very poor tire to road contact. To control this undesirable behaviour, a shock absorber keeps the spring from over reacting to every bump or dips and not only prevents but also balances excess movement of the tire and chassis.
Springs are durable items and are easily inspected. If the ride height of a vehicle has decreased excessively or a coil/leaf has broken it is advisable to replace the springs in axle sets. Consumers also often change springs to alter their vehicle's ride and handling characteristics. Spring problems are generally easy to identify.

The Safety in any kind of machine is one of the most important factor which is considered in all kind of industries. Safety has to be done on machines to avoid any kind of accident which is very harmful to worker during working on that machine.
In our project, we made a pneumatic model as same as piston cylinder arrangement which is totally mounted on metal frame. Pneumatic machine is as name implies that pneumatic means which is operated on compressed air or steam operated. Pneumatic power is used to produce different product and varies in productivity.
Projects development and implementation is increasingly technology specific and because of the diverse development in the world, we have tried to make the project up to present day's expectations.
The proposal project will thus provide substantial safety on shop floor.

Today's world requires speed on each and every field. Hence rapidness and quick working is the most important. Now days for achieving rapidness, man manufactures various machines and equipment's. The engineer is constantly conformed to the challenges of bringing ideas and design in to reality. New machines and techniques are being developed continuously to manufacture various products at cheaper rates and high quality.
The project PNEUTAMATIC COMPARATOR being compact and Portable equipment, which is skilful and is having something precise in testing the parts being manufactured. Most of the material is made available by our college. The parts can be easily made in our college work-shop. Its price is also less. This project gives us knowledge, experience, skill and new ideas of manufacturing. It is a working project and having guarantee of success. This project is the equipment useful to improve the quality of the gear being manufactured and can be made in less time, hence we have selected this project.

The SOLAR WOOD CUTTER has a reciprocating movement which operates similar to the hand hacksaw, however it cuts much faster solar power is electricity produced directly from sunlight. Solar thermal power refers to a process where the sun's energy heats a working fluid that eventually is used to do work in an engine or a turbine. Solar photovoltaic power (PV) takes advantage of the photovoltaic effect so that when sunlight hits a PV panel, it releases electrons from special layers of silicon and pushes them across an electric field. These electrons then travel through an external circuit to return to their initial state, and in the process create electric current. Adding a solar electric system in your home or business is an easy way to take advantage of regional incentives, invest in your home or businesses value and protect the environment by using clean renewable energy.
Throughout the world available free sunshine, and incentives offered by local and state governments now position grid-connected photovoltaic (PV) as an attractive investment. Today's PV systems produce electricity that has a quantifiable cash value.

We are using scissors for simple sheet metal cutting. It is a manual method so that sheet metals are to be wasted sometime because of mistakes happened such as wrong dimensions etc., and also even a simple cutting may take long time. Hydraulic machines are also for sheet metal cutting. But this method is used for only heavy metal cutting and its cost is very high. We are using a pneumatic system for sheet metal cutting in an easy way. It is operated by a pneumatic hand lever of two way control valve. Control valve is operated by a compressor

The sheet metal cutting process is a main part of all the industries. Normally the sheet metal cutting machine is manually (hand) operated one for medium and small scale industries. This project report gives an insight into the automatic shearing and feeding of sheet metal.
Automation in the modern world is inevitable. Any automatic machine aimed at the economical use of man, machine, and material worth the most. In this project pneumatic system is used for shearing in easy way which can be used in small scale industries at low cost. The sheet metal cutting machine works with the help of pneumatic double acting cylinder. The piston end is connected to the movable cutting tool. It is used to cut thin sheet metal. The cutting process makes use of a pneumatic system while the automatic feeding mechanism consists of motor-rollers assembly. A logic circuit is employed to do the interfacing between the shearing and the feeding mechanism. It further gives the glimpse of possible future developments concerned with automation of shearing process.

Recycling is wonderful way to help the environment, even if you think otherwise when you're hauling big, bulky bags crammed with empty cans to the curb. One device that will make our life easier, and our recycling haul much more compact, is the cane crushing machine. Can crushing machine are available in a number of styles, sizes and speed, with models to suit everyone from the heavy soda drinker to the recycling centre manager.
A pneumatic can crushing machine is the quickest way to crush a can. Designed for rugged performance, these tools can decrease the volume of empty cans for easy storage and disposal.
In today's times, most of the food items available in the market are canned. Cold drinks and other beverages are also packed in cans. Commercial establishments like cafeterias and bars, have to deal with these empty or leftover cans. Storage is often a problem as these cans consume too much space, thereby increasing the total volume of the trash. As canned beverages and foods are frequently consumed even in homes, these cans can take up a lot of storage space. All these storage problems can be conveniently avoided by using a cane crushing machine. As crushed cans occupy less space, you can easily keep more cans in a bag, once they are properly crushed.

Driven by studies that show that a drop in tyre pressure by just a few PSI can result in the reduction of gas mileage, tire life, safety, and vehicle performance, we have developed an automatic, self-inflating tire system that ensures that tyres are properly inflated at all times. Our design proposes and successfully implements the use of a portable compressor that will supply air to all four tyres via hoses and a rotary joint fixed between the wheel spindle and wheel hub at each wheel. The rotary joints effectively allow air to be channelled to the tyres without the tangling of hoses. With the recent oil price hikes and growing concern of environmental issues, this system addresses a potential improvement in gas mileage; tyre wear reduction; and an increase in handling and tyre performance in diverse conditions.

The problem of waste disposal has become a major problem in the developed countries as well as developing countries like India. This is due to the enormous increase in the quantity of disposable materials, the continuing storage of dumping sites, increase in the cost of transportation and its disposal. Therefore the concept of recycling the waste material and using it again in some form has gathered momentum. Also, recycling not only solves the problem of waste disposal but also reduces the cost and conserves the non-renewable natural sources.

The WiFi based secured wireless communication using RSA encryption allows us to communicate wirelessly with security feature. The data transfer during communication between two systems is encrypted using RSA encryption which is highly secure.
The data can be decrypted with correct key only, otherwise it returns some garbage value. This is two-way communication system where we can transmit as well as receive at both ends. We have used At mega microcontroller interfaced with xbee along with LCD display to send message and key, also have USB keyboards connected to each system and powered by 12V supply.
After starting system, we will able to enter message on system. The maximum limit of message is 32 character. After that system asks for key, the key limit is 16character it can be number or alphabet. Entering key will send the encrypted message to other system. Then the other system ask key to view the message. If the users enter correct key the message gets decrypted otherwise it will show garbage value thus securing the wireless communication.

Nowadays, parents are worried about their children because of the high rate of kidnapping. Moreover, parents are having long working hours, so they simply do not have as much time to spend for their children Moreover, they will be persuaded by kidnapper before they enter the school. So, it is the responsibility for the school to take care of their students and they also know in-time and able to send an alert message to their parents if the students are not at the school at school start time. This System ensures safety of the students by making their parents aware about the various important status about their students like in-time, out-time, everything about their arrival. By using RFID technology, it is easy track the student thus enhances the security and safety in selected zone. The information about student such as in time and out time from Bus and campus will be recorded to web based system and SMS will be automatically sent to their parents that the student arrived to Bus/Campus safely. SMS will be sent to parents whose children are absent without taking leave. The parents can log into system website and monitor the details of their children. The implementation of School Security System(SSS) via RFID to avoid crime, illegal activates by students and reduce worries among parents.

Modern day-to-day life of people in major cities is very demanding and the schedules are equally hectic. In such times, it is practically impossible to keep a track of all the activities/ appointments. Many a times, it happens that we may miss an important task; for example: taking medicines, attending a meeting, returning library books, paying the bills etc. And this cycle can keep going on endlessly. The human mind is not designed to multitask; it needs to work things out one at a time. This requires us to maintain our focus on the task at hand, and as a result other important things take a backstage and some may even slip out of our minds. In order to address this problem, we have come up with a Weekly Task Alerting System. This system is designed to alert the user of all the important tasks that are due on a specific day, every week. So now, the user can carry on with his/her life without any worries. The developed project is a tasks reminder app, with AI-powered Chatbot that will make user enjoy productivity. Whether your goal is to make good habits or get rid of bad ones. This application helps you to make sure that the tasks you set actually get done, with the help of its AI assistant. It monitors your android phone, pings you at times you're likely to see a notification and makes sure you don't forget about items on your to-do list. With this, which is one of the bot characters, this app brings you not only your tasks reminder but also a free productivity assistant that engages you throughout the day to create a more productive version of yourself.

This System is an innovative Application allowing the System to take the usage from Build-in classes and put a list in front of the user for him to review. The List also consists of the applications taking the battery usage and also determines the battery level. If the Battery level is low and the consumption of apps is more the system will trigger an alarm telling the user to force stop or close the apps.
This System uses Android Studio as its front end and doesn't use any backend as this type of application doesn't need one since it uses the data from the phone itself and projects to the user. So basically the system helps the user to refrain certain apps to consume more battery power and drain it quickly and user can take some actions on it.

Engineering and medical institutes usually have a number of departments and courses. Managing all these department and course data manually is a very tedious, ineffective and expensive task. So here we propose an ERP system for institutes. We aim to provide entire examination section along with faculty dashboard and training placement department in this system. Our system firstly consists of student database needed by faculty as per their requirement. The system allows to input student attendance into the database which can later be viewed by concerned faculties and students. The students may view their personal attendance and assignment submission data through a separate student login. The examination allows authorized logins to insert update timetables. The time table is then available to be viewed on the web portal. The system also allows to manage the training and placement department. Here students may view latest vacancies and the admin may post vacancies as per criteria of selection. We design this system for 8 semesters for a particular department.

This project is designed to take down employees' attendance using QR code. Every employee will be having a card that contains a unique QR code. Each QR code represents a unique id for all employees. They just have to scan their cards in front of the webcam on arriving and the system notes down their attendance as per date and time. System then stores all the employees' attendance records. It generates an overall report in excel sheet for admin and even allows him to search for particular employee's attendance.
