Hand Gesture Controlled Robot

Gesture is a way to express our ideas using our head or body.To build a hand gesture robot we will build a system using which our robot can recognize any gesture with the help of its camera,afterwards classify this gesture with the help of some algorithm and respond accordingly. To make it simple, You can understand working of this robot in following steps:
1. Send Signals using Remote Device(Your Hand, Face, Body or remote)
2. Robot receive Signals using Cameras on-board.
3. Use Algorithm to decode signal
4. Match that signal with stored signals
5.If match found then follow instructions as specified.

WiiRobot: In this project,students of Brown University build a simple and reproducible gesture based robot controller.It consists ofWii Remote,Asus eeePC,  Ubuntu Eee(as Operating System), USB Webcam,USB Bluetooth Dongle and other components. To recognize gestures, team of wiiRobot used two algorithms:
1.K-Nearest Neighbor and
2.Sum of square differences

Wireless Gesture Controlled Toy
The objective of this project is to build a toy car that can be controlled by gesture wirelessly. User is able to control motions of the car by wearing the controller glove and performing predefined gestures.
This project provides a basic platform for many potential applications such as wireless controlled toys racing games, gesture human-machine interfacing, and etc.

Hydraulic Disc Brakes

Hydraulic disc brake uses brake fluid ( Ethylene Glycol HO–CH2CH2–OH) to transfer pressure from controlling mechanism to braking mechanism. It was first used in 1914 for racing cars.It is based on the principle of Pascal Law which states that "The pressure exerted anywhere in a mass of confined liquid is transmitted undiminished in all direction throughout the liquid".
It consists of pipeline containing fluid. One end of which is connected to the master cylinder fitted with a piston attached to the brake foot pedal and other end of the pipeline is connected to the wheel cylinder having two pistons attached to the brake shoes.Area of the cross section of the wheel cylinder is greater than the area of the cross section of master cylinder.

Why we need disc brakes?

Though both systems use hydraulic brakes but in drum brakes, braking system started to fade because of servo effect, this problem has been greatly reduced in disc brake.Moreover, their are other problems within the assembly line which cause braking strength weak.

How it works?

It works on the very simple principle, when force applied at one point, it is transmitted to another point using an in-compressible fluid.When the brakes are applied the foot pedal is pushed due to which pressure is exerted on the fluid in the master cylinder.This pressure is transmitted equally and undiminished throughout the fluid and to the pistons of the wheel cylinder, therefore pistons of the engine pushed outwards and the brake shoe get pressed against the rim of the wheel due to which motion retards and vehicle starts to slow down.

Candle Light Powered Fan

Candle light fan use technology which converts heat directly into electricity using a effect called Seebeck. The only problem with these fans is their efficiency which is lesser than 10 %. To use this technology we need thermoelectric materials such as Bismuth Telluride(Bi₂Te₃) or Lead Telluride (PbTe).

Is their any difference ?

Yes, it is very different technology and unlike Dynamo (First Electric Generator, it is most commonly used for bicycle headlight),their is no moving part involved in electricity generation with thermoelectric materials.

What is the use of this project?

It helps you to understand basic concept of thermoelectricity which is used in spacecraft as Radioisotope to convert the heat released by the decay of a suitable radioactive material into electricity and in automobiles where it helps to reuse waste heat from Internal Combustion Engine.

How to Build this?

You can find complete instructions about this fan here.

Solar Powered Bag

From last few years phones are getting smart, Laptops are becoming Tablets and CD Players are becoming iPods. All these changes make us more dependent on electronic devices than ever. Though these devices keep us connected, but when battery runs out they become liability. That makes battery charging one of the most important needs of today’s world.
In my post mobile charger using bicycle, I discussed how we can charge our battery while riding on a bike. Today we will discuss about Solar powered Bag which is not only useful and handy but uses green technology too. Solar bag consists of skinny film solar cells and batteries. It contains a flexible mono crystalline solar panel, battery, charge controller, plugs, cords and light bulbs. It provides users with power up to 120 watt-hours/day, capable of powering electronic equipment's rated up to 300 W.

What is Monocrystalline solar Panel?
Monocrystalline silicon is the base material of the electronic industry. It consists of silicon in which the crystal lattice of the entire solid is continuous, unbroken (with no grain boundaries) to its edges. It can be prepared intrinsic, i.e. made of exceedingly pure silicon alone, or doped, containing very small quantities of other elements added to change in a controlled manner its semiconducting properties.

How it works?

The solar panels convert sunlight into electricity, which is stored in the batteries and can be used to power portable electronic appliances like mobile phones and mp3 players.

Advantages:

• Solar backpacks are light-weight, hence making it easier to carry. 
• Flexible solar panels also are light and portable, as well as waterproof. 
• Backpack allows patients to carry medical devices with them.

Solar Energy Project Ideas

 

Solar energy is a form of energy which is widely available in abundance and have many different uses. Energy provided by sun in 1 hour, if measured; is equivalent to energy consumed on earth in one whole year. And for this reason, their is ample opportunity to work and use this energy in comparison to any other form.

It is radiant light and heat from the sun, has been harnessed by humans since ancient times from drying clothes to generating electricity using a range of ever-evolving technologies.
Though it has many uses,but we often this energy as solar power, which is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP) with the help of lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam.

Solar Powered Motor

This project has 12V DC water pump,12V 7ah battery that was charged by my 6.5 watt solar cell and was able to pump water. This system seems to work really well.



Solar Water Heater

We can save large amount of electricity if we start using solar water heater at the place of traditional heaters. If we implement it using cogeneration, it would be really effective.

1.Painting with three colors : Art tips by Nita Leland

2.You can write your autobiography :

Writing Autobiography is one of the best things in the world. It lets us know about ourselves, and we get to know both positives and negatives of our life, who are our true friends and who are not! Sometime in our hectic life, we forget about many important parts and beings related of our lives and this project will help you in doing the same.


How to start?
Writing Biography is not an easy task, even if it's your own. So, start working towards it as soon as you finish reading this post.
To write your biography, you will need help from lot of people and this is a best part of it as you discuss about your life with others and get their point of view.

1. You need to do discussions with your family, friends and even enemies 
2. Carry pencil and paper during these discussions. 
3. Ask as many questions as you can and without getting offended with their replies.
4. Don't try to edit negatives and things you don't like.(This will help you in long term)
5. Arrange all the text chronologically and do write them in your textbook according to your convenience.
6. Read each conversation twice or more, and find a way and right words to write it interesting.
7. Write it in language you are comfortable in.

3.Prepare a poster report on some decade for eg 90's .

4.You can redecorate your room :

It will not only give you satisfaction, but also some freshness in your life. Before doing anything, you need to start with easiest task first, it will stimulate you for bigger task ahead.

Steps for Redecorating:

1. Take paper and write about changes you want to do with your room.
2. Before shifting anything, do care about your comfort, whether it will increase or not.
3. Arrange room in a way, by which you can save your time; for ex. if you like reading books on bed,make necessary arrangements, so you can grab your books right from your bed.
4. Redecorating needs time, try to do it on Saturday evening, where you will get Sunday as an extra day.You can either finish your job or if you will have finished it already, you will get a time for rest.

5.Prepare greeting cards for different occasions

Yes, you can purchase them but still handmade card is more precious gift for its receiver than any card purchased.

As you know, making cards requires creativity and various items, you should not wait for the occasion to start. Whenever you get time , make one or two of them for different occasions and give them to your loving one's when occasion arrives.

Starting early has added benefit of getting enough time to purchase things required for card making such as gum, sheets, colors etc.

6.Project about World War 2

World War 2 is one of the most important event of our history and it still affects our lives in one or other way. You can write about reasons, and long term effects of this war. You should try to find answers of questions such as How it changed the dynamics of world politics? What was the reasons behind it? Was it possible to stop it from happening?

7.Write about world most influential and important leaders

Computer Final Year Project Ideas

Computer scie nce is the scientific approach to computation and its applications.As a discipline, computer science spans a range of topics from theoretical studies of algorithms and the limits of computation to the practical issues of implementing computing in hardware and software.Due to its range sometime it gets difficult to find topic or idea for final year project.Though I have tried to share as many ideas as possible but it is difficult to cover all the projects on single page.For that reason I have divided this subject into different subsections such as PHP,Java,VB etc. and their links are available at the bottom of post. I hope you will find them useful.

Solar Energy 
Solar energy is one of my favorite topics because though its working is easy to understand but ideas related to this topic are very useful for our future energy needs.

Concept : Generally they work on this concept:

Solar Energy --->Solar Panel---> Electricity--->Machine(Grinder, Juicer, Mobile Charger, Bag etc.) or Storage(Battery)
Solar Energy-->Heat-->Cooking, Boiling, Water Filter etc .

Important thing to consider in your assignment is that how you can improve its efficiency either for boiling purpose or for heating. For ex.  Recently discussed Spherical cell concentrate more sun light at one place and therefore generates more power similarly scientist have found out that nano solar cells are more flexible and more efficient than any other cell available.

Solar Compressor:
You can build something which gets its power from Sun Energy. For e.g., power your AC of a small room using compressor which get its power from solar panel.Such as Solar Powered Air Conditioner
In this example, it is a small room. Half ton capacity will be sufficient. You will need at least kWh/24 hours. This may require 10 to 12 square meter solar panel plus battery and inverter.

Lean Manufacturing and value stream mapping

Lean manufacturing is about reducing waste spending in an operation, such as long lead times,
defects and material waste . This principle was first used in Toyota around 1988 and sometime also referred as Toyotism.

Why it is relevant now?

Competition in manufacturing sector is intense and it is increasing with each passing day. Companies are shifting their manufacturing base from developed countries to developing countries to become cost effective. To survive in this stiff competition lean manufacturing can play vital role.

Today we will discuss about major project "Value Stream Mapping for Lean Manufacturing" submitted for fulfillment of their major degrees  by Wolfgang Apel, Jia Yong Li and Vanessa Walton at WORCESTER POLYTECHNIC INSTITUTE (WPI).

In this report we will see how CIS(Central Industrial Supply), a manufacturing company that produces electro-mechanical components had reduced their production time to almost 50 %.


How it was achieved?
To achieve their target, first they used Value Stream Mapping which is a technique used to analyze and design the flow of materials and information required to bring a product or service to a consumer.This map can be drawn using paper and pencil; however more advanced maps are created
using Microsoft Visio as well as Microsoft Excel.Following is a basic drawing example showing how it is done:

At the second step this team uses arena simulation software to simulate possible future states, in third step they studied companies background and working procedure and in fourth step they gave their recommendations which you can read in their report itself.

Other Projects:

Development of a lean operations system in start-up 

Students will be expected to interface with plant management and manufacturing engineers to improve plant layout, production scheduling, process flow, work cell design, and inventory control systems. Since this project involves a start-up operation, student recommendations are expected to contribute to future design and layout of new assembly lines and inventory control systems at the facility.

I hope this article helped you in understanding Lean manufacturing implementation.

Study of Valuation models and Equity Research

The process of determining the current worth of an asset or company. There are many techniques that can be used to determine value, some are subjective and others are objective. For example, an analyst valuing a company may look at the company's management, the composition of its capital structure, prospect of future earnings, and market value of assets. Judging the contributions of a company's management would be more of a subjective valuation technique, while calculating intrinsic value based on future earnings would be an objective technique.


Role of Valuation:
Valuation is useful in a wide range of tasks. The role it plays, however, is different in different arenas. The following section lays out the relevance of valuation in portfolio management, acquisition analysis and corporate finance.

1. Valuation and Portfolio Management
1. Fundamental Analysts
2. Franchise Buyer
3. Chartists
4. Information Traders
5. Market Timers
6. Efficient Marketers
2. Valuation in Acquisition Analysis
3. Valuation in Corporate Finance

Project report given below discuss about all of the above points about Valuation Models and equity research in detail.

Electronic Fuel Injection system

Emission from the engine has been considered as the vital source of air pollution, as a result, governments of various countries starts to demand for a strict emission standard from Automobile companies. To achieve emission targets, companies need to optimize engine designs.As Fuel injection is an important step in engine, its too needs to improve. .

In this post, we will discuss how fuel injection system works,why it is required and how we can improve its working to make our engine fuel efficient?

Fuel injection is a system of admitting fuel into an internal combustion engine. It is a part of engine since automobile came into existence,though it is often used in Diesel or Gasoline engine only. Before ignition system, carburetor was used for fuel injection, where suction created by intake air accelerated through a Venturi tube to draw the fuel into the air stream.

So, how fuel injection is different from carburetor system?
In this system fuel is forced into the combustion chamber using atomizer nozzle at high pressure.It improves performance of engine considerably both in efficiency and performance.

Why Electronic fuel injection required?
In this system computers are used to calculate the amount of fuel requires by the engine at any given time.It is precise, reliable and cost effective system.It provides A/F ratio for all speed, load and temperature ranges.

Solar powered boats

Boat is important mode of transportation on water.Nonetheless, We also use it for tourism purposes to explore beautiful places,rivers and beaches. Project, we are going to discuss today is about 2-stroke engine boats we usually see on popular tourist destinations.2-stroke engines are most common form of engines used in boats but they are far more polluting than engines used in cars.With toxic fumes they spew, they are destroying our climate gradually. Moreover, this engine emits Sulfur di oxide gas which later react with oxygen found in water to produce sulfuric acid. Sulphuric Acid is harmful for the species inside the water as well as for surroundings.
In this post, we will see, how we can use solar energy in boat to replace these traditional fuel engines.Converting these engines to electric engine helps our environment and also help us to protect our resources.

Before we discuss any further, first we should look for other renewable energy sources we can use:
Wind Power :Though, It is a good option and has been used from long time back but we have two basic problems with wind powered small boat,First it requires lot of space inside the boat and second it is not very efficient.


Pedal : We can also consider using pedal boat but with pedal boat we can't travel long distances.

Hybrid(Electric + Diesel): This can be a great alternative but requires great amount of technical knowledge and processors to decide when to shift between electric to diesel and vice-versa.

Electric Boat : They solve many of the above mentioned problems and that's why we select this option, but it has problems of its own.First major problem with electric engines is their energy source itself which is  electricity.Water is good conductor and we should find a ways to make sure that electricity and water get separate always.

Things to consider:

Make your boat as lighter as you can: Remove all the unnecessary mass from the boat.

Powering for whole day of use: To make it attractive option, we need to power its engine with sufficient electricity for 24 x 7 travelling.To do so, we will require constant energy source which is solar energy and great energy storage unit which is our battery. To capture sunlight we requires solar cells which themselves have associated problems of weight and size. A medium size solar cell weights around 7 kg.So, if we use more solar cells, it will increase the mass which corresponds to more electricity consumption. To, somewhat solve this problem we can use tilting mechanism to capture more electricity from lesser cells..

Water proof batteries: When we travel on the water, their would be occasions when our batteries get wet, so it absolutely necessary to use water proof batteries.

Efficient motor: More efficient our motor, lesser the requirement of solar cells and  batteries.

Nanowires new innovation in Solar Energy

In last post, we discussed about "carbon solar cell" which is manufactured using 100 % carbon(widely available and cheaper to use). In that post, we discussed about nanotechnology and how carbon changes its behaviour on nano scale .Today, we will see how we can use nanotechnology with gallium arsenide(better alternative to silicon in solar cell).

Gallium Arsenide:

Gallium arsenide (GaAs) is a compound of the elements gallium and arsenic. It is a III/V semiconductor, and is used in the manufacturing of solar cells since 1970, when it was first introduced by Zhores Alferov in the USSR.In the early 1980s, the efficiency of the best GaAs solar cells surpassed that of silicon solar cells.These cells has also being used in rovers Spirit and Opportunity, which are exploring Mars' surface.


Concept:
According to researcher Anna Fontcuberta i Morral,inspiration of  building solar cell with vertical nanowires came into her mind by observing trees.Trees captures their sunlight from all sides(360 degree) by standing perpendicular from the ground but in our traditional cells we are doing exactly opposite and using horizontal way of capturing light and that makes our cells less effecient.In her experiment she uses nano-wires which is a nanostructure, with the diameter of the order of a nanometer (10^-9 meters).Nanowires requires less material therefore less money( If we require 40 kg in traditional method, in nanotechnology we will need only 40 grams).Nanowires are filamentary crystals with a very high ratio of length to diameter, the latter being in the nanometer range. Semiconductor nanowires are of significant interest from a fundamental point of view as they exhibit new physical and chemical properties owing to their large surface-to-volume ratio, low dimensionality and confinement in one dimension.

Carbon Solar Cells

Though, we have discussed a lot about solar energy projects, but solar energy is not economically viable for our daily use because of increasingly expensive materials used in traditional solar cells made up of silicon, which is not available in abundance and hence very costly. Today, we will discuss about carbon solar cells and how to use them to built complete carbon solar cells?


Why Carbon ?

"Carbon has the potential to deliver high performance at a low cost," said study senior author Zhenan Bao, a professor of chemical engineering at Stanford. According to Professor Bao, in the future we can use solar cells,which are coated on the surface of buildings, on windows or on cars to generate electricity

How is it possible?

When we take elements into their nano scale, their properties start to change and  it happens with carbon too.Carbon nanotubes have great electrical conductivity. Stanford researches found that, they can use nanotechnology to build new type of solar cells by just using carbon.It consists of mainly three parts,
Two Electrodes made up of Carbon Nano tubes(graphene – sheets of carbon that are one atom thick –and single-walled carbon nanotubes that are 10,000 times narrower than a human hair) instead of expensive ITO(Indium Tin Oxide) and one Active Layer made of buckyballs(soccer ball-shaped molecules with carbon atoms at each vertex just 1 nano-meter of diameter).

Buckyball(C60):

It is a spherical football shaped fullerene molecule.
Formula: C60.

Graphene:

It is a substance composed of pure carbon, with atoms arranged in a regular hexagonal pattern similar to graphite, but in a one-atom thick sheet.

Carbon nanotubes:

Carbon nanotubes (CNTs) are allotropes of carbon with a cylindrical nanostructure.

Problems:

Basic problem with carbon solar cells is their efficiency which is only 1 Percent in comparison to silicon cells with 20 Percent efficiency.People working with this technology beleives that they can increase these cells efficiency significantly by implementing some minute changes during its manufacturing.

Advantages:
Their are many advantage of using carbon cells such as
