Hand Gesture Controlled Robot

The 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, afterward classify this gesture with the help of some algorithm and respond accordingly. To make it simple, You can understand the working of this robot in the following steps:
1. Send Signals using Remote Device(Your Hand, Face, Body or remote)
2. The robot receives Signals using Cameras on-board.
3. Use Algorithm to decode the signal
4. Match that signal with stored signals
5.If match found then follow instructions as specified.

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".

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).

Physics Project Ideas

Physics projects for science and engineering students discuss ideas related to our day to day life and some of them have implemented successfully in various science fair competitions around the world. As we all know that Physics is involved in every activity we do, from a walk to talk, from electronics to robotics and from computer science to aeronautics and finding the idea on this topic is going to be very easy. So, In this post, we will discuss some of the projects based on this field

Solar Powered Bag

In the 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, when the battery runs out they become a liability. That makes battery charging one of the most important needs of today’s world.
In my post mobile charger using a bicycle, I discussed how we can charge our battery while riding on a bike. Today we will discuss Solar-powered Bag which is not only useful and handy but uses green technology too. The solar bag consists of skinny film solar cells and batteries. It contains a flexible monocrystalline 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 rated up to 300 W.

Solar Energy Projects

 

Solar energy is energy from the sun which is widely available in abundance and has many different uses. The energy provided by the sun in 1 hour, if measured; is equivalent to the energy consumed on earth in one whole year. And for this reason, there is ample opportunity to work and use this energy in comparison to any other form. In Solar energy project ideas, we are going to discuss various topics that signify how we can do optimum use of this wonderful source.

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.

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.

Final Year Computer Science Projects

CSE is the engineering branch which includes both software and hardware in its curriculum. I am writing this article to help you in finding your final year project. As a discipline, computer science has a range of topics from data structure and algorithms to writing applications for the latest mobiles and desktop computers. The latest projects include Bio-metric Systems, Mobile Apps, Websites Applications and E-Commerce. As we can do a lot of things, sometimes it becomes difficult to select one idea which not only helps us in learning new stuff but good enough for our final year major project. Though I have tried to share as many ideas as possible as you know, it is difficult to cover all the topics on a single page. For that reason I have written many sub-articles based on CS such as PHP, Java, VB, etc. and their links are available at the bottom of the post and in the right sidebar. I hope you will find them useful.

Attendance Management: Using this software you can maintain the attendance of the employees. Moreover, it can generate monthly and daily reports of their attendance and salary slips.

Mechanical engineering Project Ideas

In the field of mechanical engineering, we have a vast range of topics to select from. At present, companies and governments are dealing with two issues. First, is about global warming and the other is about competition.

For both these issues, mechanical engineers can contribute a lot. For example, to improve the competitiveness of the organization, you can build automation tools or robots which can help the company to improve its efficiency and similarly for global warming, you can bring some news ideas to either save energy or generate it without doing harm to nature.

The biggest positive about these is that solutions to both these issues are going to come from mechanical. This is the reason, I always recommend students to select topics which are related to either robotics or renewable energy.

I myself tried to find all the latest topics from around the world and write about them to give you some more insight into what's happening around.

Robotics 

Robotics Projects Robotics would be a good choice in mechanical projects: Robots are very attractive in comparison to other projects and if everything goes well they will make you win.

Lean Manufacturing and value stream mapping

Lean manufacturing is about reducing waste spendings 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 to as Toyotism.

There is no set of standard procedures about Lean Manufacturing but instead, it's about designing the optimum process with the use of set of standard practices to increase production or output.

Why it is relevant now?

Competition in the 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 a vital role.

Today we will discuss major projects "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 %.

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.

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 start 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 the engine, it's too needs to improve.

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

Solar powered boats

The boat is an important mode of transportation on water. Nonetheless, We also use it for tourism purposes to explore beautiful places, rivers, and beaches. The project, we are going to discuss today is about 2-stroke engine boats we usually see on popular tourist destinations.2-stroke engines are the 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 dioxide gas which later reacts with oxygen found in water to produce sulfuric acid. Sulphuric Acid is harmful to the species inside the water as well as for the surroundings.
In this post, we will see, how we can use solar energy in the 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 for a long time back but we have two basic problems with a wind-powered small boat, First it requires a lot of space inside the boat and second it is not very efficient.

Nanowires new innovation in Solar Energy

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

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 have also been used in the rovers Spirit and Opportunity, which are exploring Mars' surface.

Carbon Solar Cells

Though we have discussed a lot about solar energy projects, 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 carbon solar cells and how to use them to built complete carbon solar cells?
