SECOND YEAR STUDENTS
1.HYDRO POWER PLANT
Hydroelectricity is the term referring to eletricity generated by hydropower; the production of electrical power through the use of the gravitational force of falling or flowing water. It is the most widely used form of renewable energe, accounting for 16 percent of global electricity generation – 3,427 terawatt-hours of electricity production in 2010,and is expected to increase about 3.1% each year for the next 25 years
2.AUTOMATIC ON /OFF IRRIGATION PUMP
We have a 5 zone sprinkler system. Zones 1-3 work perfectly fine. When zones 4 and 5 come on the pump will turn on and off. We've tried cleaning the sprinkler heads of these zones but no luck with the pump. I read on a website to open the bleed valve on the solenoid valve. I opened the bleed valve slightly on zone 5 and the pump stayed on but when I tried turning the system off with the valve still open the pump would turn on and off again. So I had to shut the bleed valve.
3.HYDRAULIC LIFT
One of the most important equipment used in transporting goods and people is the hydraulic lift.
By the way of hydraulics, such lifts are able to carry heavy loads with great ease, and lift it vertically. Hydraulic lifts come in the form of passenger lift, service lifts (to carry goods to higher floors etc.) For more than 150 years since the birth of the modern elevator, lifts have formed an important part of our life. While lifts are widely used for transporting men to higher floors, and in multistoried buildings all over the world, there is also a completely different use for lifts, as far as work and industries are concerned.At such places, lifts are increasingly required to raise heavy loads in the form of machinery, and equipment at different levels. Due to the heavy weight to be lifted, the standard roped elevator design is not very efficient for the purpose. 4.VARIOUS TESTING OF ENERGY BY USING BATTERY |
We tested each of the flashlights by using the two test batteries. We then labelled each flashlight with the battery brand name and put the different batteries in each marked flashlight.Before going to bed we will turn on all the flashlights at the same time and left them on overnight. We'll note down the time that the flashlights were turned on. When we wake up we will watch the flashlights until they go out and will record the time. If one goes out before we wake up, we will gettwomoreof the same type of battery and watch it during the day.This is a list of energy
5.WATER LEVEL INDICATER
The connections and arrangements are made as shown in the figure above. The +9V is supplied to water using metal contact. In this circuit all the transistors are working as a switch. When the water touches the metal contact in which base of each transistor is connected, a small current flows and turns on the transistor. When a transistor turns on, LED connected to it glows. Thus LEDs will be turned on depending up on the level of water. By using a relay we can also control the level of water.Nowadays everybody has overhead tank at their homes. But everyone who has a water tank above knows the kind of problems that they face. Firstly there is no system to track the water in the tank. Then there come a secondary problem that is when their water pump is started they have no idea when it gets filled up and sometimes there are situation where the pump keeps onpumping water to the tank and the water starts spilling out from the tank. There iswastage of energy as well as wastage of water.
6.PRODUCING CURRENT USING POTATOS
Batteries generate electricity through a chemical reaction between two different electrodes and one electrolyte. Use of Copper and Zinc electrodes and Sulfuric acid as electrolyte is a proven method for this process. We are wondering if we can use any other liquid as electrolyte? This gave us the idea of using a potato as electrolyte. After all a fresh potato has a lot of juice that may serve our purpose as electrolyte.Potato juice contains many water soluble chemicals that may cause a chemical reaction with one or both of our electrodes. So we may get some electricity from that.
7.WATER CANDLE
Holding a Water Candle in your hand will increase the monster spawn probability to 133% and the maximum number of monsters to 150%.They produce light like a regular torch or candle would. If you have them on tables as props, they produce some lovely spooky lighting. However, they don't increase the spawn rate like this.To increase the spawn rate with a water candle, hold it in your hand. It can't just be in the top row of your inventory - it must be the currently active and held item.Keep a weapon handy so that you can swap back and forth between your water candle and weapon as necessary. You can't hold both at the same time, but you can at least run around luring enemies out with your water candle, attack them all, then return to luring enemies out.
8.TESTING OF CONDUCTORS USING LED
There is disclosed a cable test unit for use in testing multi-conductor cables containing a plurality of wire pairs. The invention includes means for supplying a constant D.C. voltage; a time-governed oscillator; a recycle pulse generator for releasing sequential pulse outputs; a connector test base having anode and cathode sides; a plurality of LEDs, each corresponding to a respective wire pair, and electrically connected to the test base; means for inhibiting induction across all wire pairs except the pair at which a pulse output from the recycle pulse generator exists; and means for recycling the pulse generator. The current flow characteristic across a given wire pair varies as a function of its structural condition as either a short, open, or crossed circuit, or a loose connection, and such characteristic is reflected in the visual appearance and behavior of the LED corresponding to that wire pair.
9.ALARAM SYSTEM
Electronic alarm systems are made up of three component parts designed to detect, determine and deter criminal activity or other threatening situations. An alarm system can detect an event such as an invasion, fire, gas leak or environmental changes; determine if the event poses a threat; and then send a notification about the event. Detect The component of an alarm system that detects activity is called a sensor. Here are some common types of sensors that may be used to protect your home.
10.SOLAR LAMP
Solar-powered lighting consists of a solar panel or photovoltaic cell that collects the sun's energy during the day and stores it in a rechargeable gel cell battery. The intelligent controller senses when there is no longer any energy from the sun and automatically turns the LED light on using a portion of the stored energy in the rechargeable battery.A solar light consists of the following components:If you pop off the cover, you will find that all of the working components are mounted as a single unit. On the back side you see this:Next, we'll take a closer look at some of these components.
11.STAIRCASE WIRING
Stair case wiring circuit diagram, OR How to control a lamp from two different places by two ,2-way switches?Staircase wiring circuit diagram very simpleThis is the staircase wiring circuit diagram. Here we can control a bulb from two different places by using two, 2-way switches.Now consider this circuit diagram. In this case you can see that circuit is complete and bulb is ON. Suppose you want to OFF bulb from the upper switch at top of stair, simply Switch OFF the switch then circuit will break and the bulb will be OFF. You can switch ON the bulb again to switch ON this Switch. In other words you can OFF and ON bulb from upper switch at the top of stair. Obviously; you can do same from the upper and bottom switch, so let’s see how we can do that from that switch at the bottom of stair. Now return to circuit again in the pic, In this case you can see that circuit is complete and bulb is ON. Suppose you want to OFF the bulb from the lower switch at bottom of stair. Simply OFF the switch, then again circuit will break and the bulb will be OFF. You can switch ON the bulb again to switch ON this Switch
12.WATER LEVEL CONTROLLER BY USING 555 TIMER IC
How many times did your overhead water tank overflows due to your forgetfulness? It is a frequent problem in all homes where people turn ON the water pump and forget to turn it off when the water is filled. This project is made to solve this problem.In this project, we are using a water level alarm using simple and low cost hardware using a 555 timer circuit. The aim of this project is to make a water level detecting alarm with simple and low cost hardware without compromising on the performance of the device.
13.ROTATING MIXIE BY USING BATTERY
Disclosed is a battery-operated utensil for mixing and pouring drinks and the like. It uses a separate motor to drive a shaft carrying mixer blades, and a separate motor to drive a pump. The motors are turned on one at a time, and drive the respective shafts directly, thus eliminating the use of components such as gears, clutches or ratchets. The design allows ingredients to be poured into the mixing vessel through a filling chute, without removing the housing which caps the vessel, as well as for convenient removal of the housing when necessary, as for cleaning. Various other features are provided to make the utensil particularly inexpensive to manufacture and convenient to use.
THIRD YEAR STUDENTS
1.CANDLES MAKE ELECTRICITY
In the lead up to the New Orleans Mini Maker Faire on Saturday, Matthew Candler, the founder of 4.0 Schools, debuted an electric motorcycle he's been working on for two years. The bike performed well on its maiden ride, though it still requires lights, turning signals, and a horn, among other additions, to make it street legal. Candler plans to answer questions about the bike at the Mini Maker Faire.
2.WINDMILL ELECTRICITY
Windmill electricity Mankind been harnessing the wind's energy for many years. From Holland to traditional farms around the world, windmills were used in the past for pumping water through primative irrigation systems or used to grind grain. Then, the wind turned large "sails" which were connected by a long vertical shaft that was attached to a grindnig machine or to a wheel that turned and drew water from a well. Today's turbines - can utilize the energy of the wind to turn large metal blades which in turn spins a generator that manufactures electric power.
3.RECYCLE BOTTLE LAMP
I consider different types of light the most important part of home decoration. The light can either, give a special mood to your apartment like these String Lights ideas, or ruin it entirely when it is mismatched.
I had always liked table lamps of exceptional patterns, especially when they were handmade
FINAL YEAR STUDENTS
1.SOLAR COOKER
A solar cooker is a device which uses the energy of direct sunlight to heat, cook or pasteurize food or drink. Many solar cookers presently in use are relatively inexpensive, low-tech devices, although some are as powerful or as expensive as traditional stoves,[1] and advanced, large-scale solar cookers can cook for hundreds of people.[2] Because they use no fuel and cost nothing to operate, many nonprofit organizations are promoting their use worldwide in order to help reduce fuel costs (for low-income people) and air pollution, and to slow down the deforestation and desertification caused by gathering firewood for cooking. Solar cooking is a form of outdoor cooking and is often used in situations where minimal fuel consumption is important, or the danger of accidental fires is high, and the health and environmental consequences of alternatives are severe.[3]Many types of solar cookers exist, including parabolic solar cookers, solar ovens, and panel cookers, among others.
