The sensor is used to detect the brake wire. There is any disconnection of the brake wire or cutting of any few turns of brake wire, the control signal to the alarm unit. Similarly the heat sensor is fixed to the engine and this heat is measured and giving the alarm signal when the engine heat exceeds the setted temperature limit.\r\n\r\nINTRODUCTION\r\n\u00a0\r\n\u00a0Car safety is the avoidance of automobile accidents or the minimization of harmful effects of accidents, in particular as pertaining to human life and health. Special safety features have been built into cars for years, some for the safety of car's occupants only, and some for the safety of others. We have pleasure in introducing our new project \u201cAUTOMATIC HEAD LIGHT DIM\/BRIGHT CONTROLLER AND ENGINE OVER HEAT ALARM\u201d, which is fully equipped by sensors circuit, dim\/bright light and engine over heat alarm circuit. It is a genuine project which is fully equipped and designed for Automobile vehicles.\u00a0\r\n\r\n\r\n\r\nAutomatic Brake Failure Indicator and Engine Overheating Alarm\r\n\r\n\r\n\r\nThis forms an integral part of best quality. This product underwent strenuous test in our Automobile vehicles and it is good. Man has needed and used energy at an increasing rate for its sustenance and well being ever since he came on the earth a few million years ago. \u00a0Primitive man required energy primarily in the form of food. \u00a0He derived this by eating plants or animals, which he hunted.\r\nSubsequently he discovered fire and his energy needs increased as he started to make use of wood and other bio mass to supply the energy needs for cooking as well as agriculture. \u00a0He added a mew dimension to the use of energy by domesticating and training animals to work for him.\u00a0\r\n\u00a0With further demand for energy, man began to use the wind for sailing ships and for driving windmills, and the force of failing water to turn water wheels. Till this time, it would not be wrong to say that the sun was supplying all the energy needs of man either directly or indirectly and that man was using only renewable sources of energy.\r\n\r\nThe major components of the project are follows\r\n\r\n\r\n \tLDR Sensor and Heat Sensor\r\n \tFrame\r\n \tBattery\r\n \tDim\/Bright Light (Head Light)\r\n \tRelay\r\n\r\n\r\nBLOCK DIAGRAM\r\n\r\n\r\nBLOCK DIAGRAM OF Automatic Brake Failure Indicator and Engine Overheating Alarm\r\n\r\n\r\nADVANTAGES\r\n\r\n\r\n \tLow cost automation project.\r\n \tLess power consumption\r\n \tOperating Principle is very easy.\r\n \tInstallation is simplified very much.\r\n \tLess time and more profit.\r\n\r\n\r\nAPPLICATIONS\r\n\r\n\r\n \tFour wheeler application\r\n \tTwo Wheeler Application\r\n\r\n\r\nDISADVANTAGES\r\n\r\n1.\u00a0This circuit is not working on low rain fall.\r\n2.\u00a0This system applied in the case of water falling on the class period only.\r\n3.

Normally the wood Crushing machine is manually hand operated one for Wastage Collecting wood industries. In our project is \u201cmotorized wood Crusher\u201d.\r\nAutomation in the modern world is inevitable. \u00a0Any automatic machine aimed at the economical use of man, machine, and material worth the most. In our project is Pneumatic Actuator and control Valve unit is used for automation. The motorized wood Crushing machine works with the help of high torque A.C motor. The A.C motor is connected to the gear Arrangement. It is used to press the wastage wood in wood industries and agricultural fields. The machine is portable in size, so easy transportable. India being one of the largest wood industries, lack in technology of processing industry. Till date there were many techniques involved to crush the waste wood. But most of them involved, lead to failure. Even now the basic conventional process is being followed. Most of them are not aware of the importance of processing industry in India. Some projects were designed in recent times but the required target was not achieved. The traditional way of wood crushing was manually done. Day today the wood crushing remains untold miseries to farmers and coconut vendors due to high labour demand and labour cost.\r\nINTRODUCTION\r\n\r\n\r\nThis 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 with changing demands on physical input as the degree of mechanization is increased.\r\nAgriculture is the potential area that has to be automated which can be applied for activities like irrigation, harvesting, plugging, weeding, etc. Our project aims at automating the process of waste wood crushing by using some pure mechanical oriented thoughts. This machine is specifically designed to crushing the waste wood pieces using rotating spikes to penetrate and effectively engage. The interaction of the rollers in combination with the gripping action of the spike serves to tear away the husk from the nut leaving the nut intact.\r\n\r\nOBJECTIVE OF THE PROJECT\r\n\r\n\r\nThe processing industry in the field of agriculture has a booming scope in the market. The utilization of byproducts also plays a key role in the processing industry. To concentrate with the study undergone, the wood crusher remains unsolved due to failures. This project is a prototype of the wood crushing machine where all the factors are considered like:\r\n\u2022 Cost factor\r\n\u2022 Safety factor\r\n\u2022 Time factor\r\n\r\nWORKING PRINCIPLE\r\n\r\n\r\n\r\nAUTOMATIC WOOD CRUSHER WITH CONVEYOR BELT\r\n\r\n\r\n\r\n\r\n\r\nAs the power is supplied to the motor, it acts as a driver with 1440 rpm and drives the gear box. From the gear box the speed is reduced to 28 rpm, which in turn supplies the power to the shaft. A crown gear is introduced to distribute the power equally to all the rotating blade shafts.\r\n\r\nThe crown gear is fixed by surface contact to which pinion gears are mounted over. The shaft remains as a support for the holing system.\r\nAPPLICATIONS\r\n\r\n \t\u00a0This machine is very useful for wood industries\r\n \t\u00a0This machine is used to crush the all types of cans.\r\n \t\u00a0All agricultural Application\r\n\r\nDISADVANTAGES\r\n\r\n \tWhile working, the compressed air produces noise therefore a silencer may be used.\r\n \tHigh torque can not be obtained\r\n \tLoad carrying capacity of this unit is not very high\r\n\r\n\r\nADVANTAGES\r\n\r\n \tThe motorized crusher is more efficient in the technical field\r\n \tQuick response is achieved\r\n \tSimple in construction\r\n \tEasy to maintain and repair\r\n \tCost of the unit is less when compared to other machine\r\n \tNo fire hazard problem due to over loading\r\n \tComparatively the operation cost is less\r\n \tThe operation of wood Crushing is faster because the medium used to\u00a0Operate.\r\n\r\n\r\n&nbsp;\r\n\r\n\r\n\r\nMore Resources \/articles\r\nAgricultural Project List - Abstract , Report Download\r\nNew Mechanical Projects 2020 ( All Projects Post Index List )","headline":"AUTOMATIC WOOD CRUSHER WITH CONVEYOR BELT","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2015-11-09","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2015\/11\/AUTOMATICWOODCRUSHERWITHCONVEYORBELT-206x300.jpg","height":300,"width":206},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <article class="article-card horizontal "> <a href="//www.gunkrazy.com/auto-feed-pneumatic-sheet-metal-cutting-machine-projec/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2015/11/fabricationofsheetmetalcuttingmachine-300x201.jpg')"></div><span class="sr-only">link to AUTO FEED PNEUMATIC SHEET METAL CUTTING MACHINE</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/auto-feed-pneumatic-sheet-metal-cutting-machine-projec/">AUTO FEED PNEUMATIC SHEET METAL CUTTING MACHINE</a></p></header><div class="excerpt"><p>AUTO FEED PNEUMATIC SHEET METAL CUTTING MACHINE

This machine can also be installed in the lab for the experiment and demonstration to engineering students. Thereby gaining the hand sum experience and knowledge on how to design and fabricate the mechanical system.\r\n\r\nDownload Report :\u00a0Pneumatic Sheet Metal Shearing\/Cutting Machine report\r\n\r\n&nbsp;\r\nIntroduction:\r\n\r\n\r\nThe sheet metal cutting process is a main part of the all industries. Normally the sheet metal cutting machine is manually hand operated \u00a0One for medium and small scale industries. Automation in the modern world is inevitable.\r\n\r\nAny automatic machine aimed at the economical use of man, machine, and material worth the most. In our project is solenoid valve and control timing unit is used for automation.\r\n\r\n&nbsp;\r\nWorking principle\r\n&nbsp;\r\n\r\nThe sheet metal cutting machine works with the help of pneumatic double acting cylinder. The piston is connected to the moving cutting tool. It is used to cut the small size of the sheet metal.\r\n\r\nAuto Feed Pneumatic Sheet Metal Cutting Machine\r\n\r\n\r\nThe machine is portable in size, so easy transportable.\r\n\r\nThe compressed air from the compressor is used as the force medium for this operation. There are pneumatic double acting cylinders solenoid valves, flow control valve and the timer unit is used. The arm from the compressor enters to the flow control valve. The controlled air from the flow control valve enters to the solenoid valve. The function of solenoid valves all of air correct time interval. The 5\/2 solenoid valve is used.\r\n\r\nIn one position air enters to the cylinder and pushes the piston so that the cutting stroke is obtained. The next position air enters to the other side of cylinder and pusses the piston return back, so that the releasing stroke is obtained. The speed of the cutting and releasing stroke is varied by the timer control unit circuit.\r\n\r\nComponent Description:\r\n1) Air Compressor:\r\n\r\nAn air compressor is a device that converts power (usually from an electric motor, a diesel engine or a gasoline engine) into kinetic energy by compressing and pressurizing air\r\n\r\n\r\n2 ) Pneumatic Cylinder :\r\n\r\n\r\nPneumatic cylinder (sometimes known as air cylinders) is mechanical device which use the power of compressed gas to produce a force in a reciprocating linear motion.\r\n\r\n\r\nsingle acting cylinder Diagram\r\n\r\n\r\n\r\nBecause the operating fluid is a gas, leakage from a pneumatic cylinder will not drip out and contaminate the surroundings, making pneumatics more desirable where cleanliness is a requirement. Like hydraulic cylinders, something forces a piston to move in the desired direction. The piston is a disc or cylinder, and the piston rod transfers the force it develops to the object to be moved.\r\n\r\n\r\n3) Solenoid Valve\r\n\r\nA solenoid valve is an electromagnetically operated valve. The valve is controlled by an electric current through a solenoid: in the case of a two-port valve the flow is switched on or off; in the case of a three-port valve, the outflow is switched between the two outlet ports. Multiple solenoid valves can be placed together on a manifold.\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\nsolenoid valve used for mechanical project\r\n\r\n\r\nSolenoid valves are the most frequently used control elements in fluidics. Their tasks are to shut off, release, dose, distribute or mix fluids. They are found in many application areas. Solenoids offer fast and safe switching, high reliability, long service life, good medium compatibility of the materials used, low control power and compact design.\r\n\r\n\r\n\r\n\r\n\r\nMore Resources \/articles\r\nMachine Tool , Manufacturing Projects List - Abstract , Report\r\nDesign and Fabrication projects - Abstract , Report Download\r\nNew Mechanical Projects 2020 ( All Projects Post Index List )\r\n\r\n\r\n\r\n&nbsp;","headline":"AUTO FEED PNEUMATIC SHEET METAL CUTTING MACHINE","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2015-11-08","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2015\/11\/fabricationofsheetmetalcuttingmachine-300x201.jpg","height":201,"width":300},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <article class="article-card horizontal "> <a href="//www.gunkrazy.com/automatic-braking-system-to-avoid-road-accidents/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2015/11/pneumaticbraqkingsystem.jpg')"></div><span class="sr-only">link to Automatic Braking System To Avoid Road Accidents</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/automatic-braking-system-to-avoid-road-accidents/">Automatic Braking System To Avoid Road Accidents</a></p></header><div class="excerpt"><p>Automatic Braking System To Avoid Road Accidents   Objective:

Mainly it is used when drive the vehicles in night time. Mostly the accident occurred in the night time due to long travel the driver may get tired. So the driver may hit the front side vehicle or road side trees. By using this project the vehicle is stopped by auto braking system. So we can avoid the accident.\r\n\r\nBrief Methodology:\r\n\r\n\r\nBlock Diagram Of Auto Braking System For Automobile\r\n\r\n\r\n\r\n\r\nThis project is designed with microcontroller, Ultrasonic Transmitter, Receiver, Signal conditioning unit, Analog to Digital converter, Driver Circuit and Mechanical arrangement.\r\n\r\nThe oscillator circuit generate 40KHZ frequency signal. It is transmitted through ultrasonic transmitter. The ultrasonic receiver is used to receive the reflected wave due to in front of the vehicle. Then the reflected wave is given to signal conditioning unit in which the incoming wave is amplified and converted into square pulse. Then the square pulse is given to ADC. Depends upon distance the reflected wave strength is varied.\r\n\r\nADC is nothing but analog to digital converter, which converts the input analog signal into corresponding and digital signal. This digital signal is given to microcontroller.\r\n\r\nThe microcontroller may Atmel or PIC both are flash type reprogrammable microcontroller in which we have already programmed. So it received the signal from ADC displayed on the LCD display. This is equal to distance between the vehicle and front side object. The object may vehicle, trees or road barriers. Nearest dangerous distance value is already stored in the microcontroller. When measured distance is reached this value, microcontroller automatically activates the relay driver circuit. The relay output is directly connected to mechanical arrangement. Through this mechanical arrangement braking is provided and vehicle is stopped in order to avoid the accident.\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\nMore Resources \/articles\r\nAutomobile Engineering Projects List - Abstract , Report\r\nNew Mechanical Projects 2020 ( All Projects Post Index List )","headline":"Automatic Braking System To Avoid Road Accidents","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2015-11-08","mainEntityOfPage":"False","dateModified":"February 23, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2015\/11\/pneumaticbraqkingsystem.jpg","height":190,"width":190},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <article class="article-card horizontal "> <a href="//www.gunkrazy.com/project-on-fully-automated-fire-fighting-robo/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2015/11/Firefightingrobots-300x213.jpg')"></div><span class="sr-only">link to Project On Fully Automated Fire Fighting Robot</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/project-on-fully-automated-fire-fighting-robo/">Project On Fully Automated Fire Fighting Robot</a></p></header><div class="excerpt"><p>A FULLY AUTOMATED FIRE FIGHTING ROBOT

Robotics has gained popularity due to the advancement of many technologies of computing and nanotechnologies. So, I have decided to design something that can make humans life easier and comfortable. Here my interest of review is to make a fully automated fire fighting robot which can help in dealing with many fire problems in households and small scale industries. Now I am not concentrating on making a firefighting robot that can deal with fire on large scale because I want to proceed by step by step. The need of the hour is to make a device which can detect fire, even if it is small and take the necessary action to put it off. Many household items catch fire when someone is either sleeping or away and that lead to many hazardous conditions if the fire is not putted off in time. So, my work as an electronics and computer engineer is to design and build a system that can automatically detect and extinguish fire. I have used very basic concept here, easy to understand from the prospective of beginners or for the masters of this field.\r\n\r\nINTRODUCTION\r\n\u00a0\r\nMy research paper is describes the design of a small autonomous Fire Fighting Robot. I have worked on the same project at my college presenting a synopsis showing its basic construction and working. The Fire Fighting Robot is designed to search for a fire in a small floor plan of a house of the specific dimensions, extinguish the fire with the help of the front fan of a toy hovercraft, and then return to the front of the house. This mission is divided into smaller tasks, and each task is implemented in the most efficient manner such as self autonomous start of the robot, navigation of the robot in every room step by step, finds the fire in a specific room, approaches the fire at a very fixed distance, extinguishes it and finally returning to the front of the house. The self start of the robot is governed by a Tone Decoder which detects the tone of frequency up to 3.5 KHz which is emitted by a fire alarm during fire. The navigation of the robot throughout the house is achieved by data provided by a line tracker and ultrasound transducers. Finding the target or fire is achieved by the Flame Sensor which detects the temperature density in various parts of the floor plan. This is accompanied by UVTron flame sensor. The deployment of the extinguishing device is implemented with a fan controlled by servos. The very important and crucial concept of this Fire Fighting Robot is that it navigates and extinguishes the candle by colliding with the wall of the floor plan to a least extent.\r\n\r\n\r\n\r\nFire Fighting Robot\r\n\r\n\r\nSee Also:\u00a0Seminar and Project On Fire fighting robot\r\n\r\nExplanation\r\nFire Detector and Extinguisher Robot is operated to detect the fire and also to extinguish it. It can be operated in two modes one is manual mode and other is autonomous mode. Manual mode is operated using \u00a0joysticks and for autonomous mode there is no human intervention. In manual mode direction of the robot is controlled using joysticks, even pump is operated manually. In autonomous mode IR sensors are used to detect the fire and robot is coded accordingly to move in the direction of detected fire. In this robot has a switch which is used to switch between manual and autonomous mode.\u00a0\r\n\r\nThe main components are :\r\n\u2022 IR sensors\r\n\u2022 Joysticks\r\n\u2022 Motor drivers\r\n\u2022 DC motors\r\n\u2022 Pump\r\n\r\nIR Sensors:\r\n\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0IR Photo Diodes are used as sensors. These sensors \u00a0are connected to ADC pins of the microcontroller. IR \u00a0Photo diodes are connected in reverse bias to be operated as \u00a0photo diodes otherwise they will be operated as normal diodes. The voltage variations of the sensors is given as inputs to the Micro controller and accordingly the robot is operated.\r\n\r\nJoysticks:\r\n\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 The direction of the robot is controlled using joysticks. The terminals of joysticks is connected to ADC pins of micro controller. Joysticks are usually the potentiometer, the potential variations is given as an input to micro controller and robot is operated accordingly.\r\n\r\nMotor Drivers:\r\n\r\nMotor drivers are used to describe the direction of movement of the robot. It is used to give high voltage and high current as an output to run the motors which are used in the project for the movement of the robot.\r\n\r\nDC Motors:\r\n\u00a0In this project we use simple DC motor for the rotation of the wheel which are responsible for the movement of the robot. Usually DC motors convert electrical energy into mechanical energy.\r\n\r\nPump:\r\n\r\nPump is a mechanical device which is used to pump water on to the fire to extinguish it. It uses a simple motor to pump water.\r\n\r\nApplications:\r\n\r\n\u2022 Can be used in record maintaining rooms where fire can cause lose of valuable data.\r\n\u2022 Can be used in Server rooms for immediate action in case of fire\r\n\u2022 Can be used in extinguishing fire where probability of explosion is high.

Imagine never having to plug your cell phone into the wall again now you can just plug it into your cycle \u201cWatts Maker\u201d cell phone charger. The system consists of a small \u00a0generator that provides power to your mobile phone while you take an evening ride around the neighborhood or pedal to work. This model takes about 90 minutes to go from dead to fully charged, and it produces energy as long as the wheels keep turning.\r\n\r\nINTRODUCTION\r\n\r\nThis winter, my dad and I took up the project of building a simple pedal-powered cell phone charger to mount on my bicycle. Cell phones are small potatoes in the big picture of energy consumption, but the apparatus we built could be a very practical concept for those on self-supported bike tours or those living temporarily in situations without electricity. Just unplug your phone from the wall, and in the time that it takes for you to rig up this gizmo your phone will be out of juice and you'll be due for a long Ride A couple visits to the local hardware store and Radio Shack secured all the parts we needed for the job.\r\n\r\nWORKING PRINCIPLE\r\n\r\n\r\n\r\nPedal Operated Cell Phone Charger Project\r\n\r\n\r\nInitially starting with cycle pedaling operation is manually. The sprocket is coupled to another sprocket with the help of chain drive. The second sprocket shaft is coupled to the Cam plate with the help of End bearings.\r\n\r\nWhen engaged, the generator wheel rolls against the cycle tire. The motion produces electricity, and the greater your speed, the greater the voltage output. The cord from the generator leads first to the circuit board's bridge rectifier, which converts the AC to DC. In other words, the up-and-down, positive-to-negative current becomes a steady positive current. Then, the capacitor levels out the DC voltage, producing a steady voltage inflow to the voltage regulator. The voltage regulator is crucial, as the phone only needs 3 to 4 volts to charge, whereas fast pedaling can produce 30 volts or more, which is enough to fry the average cell phone. The regulator controls the voltage, putting a five-volt ceiling on the power entering the phone.\r\n\r\nAPPLICATIONS\r\nSince the Pedal operated cell phone charger is more efficient it is used for mobile charger.\r\nAll mobile charging \u00a0Applications\r\n\r\nADVANTAGES\r\n\r\n1.
