Prosthesis:Low cost artificial leg

Prosthetic limb is an artificial device extension that replaces a missing body part. It is part of the field of bio mechatronics, the science of using mechanical devices with human muscle, skeleton, and nervous systems to assist or enhance motor control lost by trauma, disease, or defect.

In this world there are many people who have some kind of disability.Engineers are working day and night to   make artificial limbs which works like a normal leg and controlled by human brain. Even though they are successful in building these limbs,but in developing world there are plenty who can't afford there ultramodern limbs because of its high cost.

Bicycle powered Cell phone charger

 Mobile Phone has become very effective tool in modern world mode of communication. Even in Developing countries like Kenya (as shown in video below) it is easily accessible (thanks to china's cheap manufacturing) and airtel (cheap phone calls) mobile is within the reach of poor, but problem is how to charge a phone without a supply of electricity. In Kenya and other developing countries in Africa, charging a phone is big challenge because electricity is still a distant future for them.

Man Powered Helicopter

A human-powered helicopter is a helicopter designed to carry at least one person but limited to using only what power is provided by the person(s) on board, usually by pedalling. A high power-to-weight ratio is needed as in all helicopters. Such aircraft must be light and must have efficient rotary wings. Efficiency for human powered purposes means that the rotors must generate great lift but cause little drag, because drag consumes power.

Business project ideas

 Thinking of starting a new venture and don't know how? This same problem has been faced by many of us. Starting a business looks difficult initially but it is not a rocket science. Fundamentals of business has not changed from centuries. Even though , we are living in a technology world and sometime feels that we need to think out of the box for running successful business , but in real life, we do not. In this post we will discuss about some really good ideas.Remember , starting a business is not a big deal but running it successfully requires dedication and determination.

There are lot of businesses you can do but I will suggest ideas which can be implemented with minimum or no costing at all.Look around and pick something you are passionate about :

Part Time Work having Potential to become full time :

1.Start a blog: This doesn't look like a business , but it is really good option with no investment.Wanna write one , start with

2.Write a book: Yes, you don't need to be perfect for writing a book. Just start doing it write one page a day.Its really fun and you will able to complete  at least 200 pages at the end of a year.

3.Education Consultant: Do research about education environment, colleges , admission procedure and stuff like that and provide paid consultancy for that.

4.Property Dealer : Help sellers and buyers to get right kind of property and get hefty commission for that.

Businesses with Investment  :

Event Management Company : You can start your own event management company , which organize events such as marriages in your city.Hire some quality people from this field, they bring experience as well as contacts for you.

Distribution ship :  Get distribution ship of any reputed company with minimum presence in your city. If its possible find some new companies in the market whom you believe to get bigger by time. Advantage of associating with new company is that you will get good share in profit with minimum competition including help from the companies administration.

Auction Website like Ebay :  You can start your own auction site like ebay.With the open source community around it doesn't cost much,just download auction site code from sites like sourceforge.
Restaurant :  If you love cooking and have something special in that, you can start your own restaurant.For a start, you can serve only selected dishes and as word of mouth spread you can add more food items later.

Fruit and Vegetable : This business requires big chunk of land and time. Grow fruits or vegetable with working partnership with experienced local farmer. Use best technology available to make this business profitable such as Sprinklers, Drip Irrigation or Bird Scarer.

Business of Finance: This requires lot of money but you can arrange it with profit sharing basis with money lender. To run this business successfully you can ask your customer for some security like gold.

Packers and Movers: People often face difficulty to shift there offices or homes from one place to another.You can become there helping hand.

Importer : If you have good market sense , you can import cheap foreign goods from developing country like China and sell it to the shopkeepers.

Tricycle powered by pedals and electricity

An electric tricycle is a bicycle having three wheels with an electric motor used to power the vehicle.Tricycle which is powered by electricity would be very helpful for people who use cycles in there daily life. It would not only increase speed of the cycle but also helps them in paddling.

PLC automatic Bottle Filling Machine

Importance of Bottle filling is realized by us when we see how many bottle we use in our daily life. Bottles are everywhere from cold drink to beer ,toilet cleaner to medicine etc etc.These bottle is filled with the help of filling machine without which it would have very difficult task. This project is about these machines.

Can Crusher Experiment

Can crushing is very important to reuse aluminum in these cans. Moreover this contribute to significantly lower the waste management problem. These can crusher can be made to work mechanically so that no electricity is needed to crush them.

Pedal operated power generating system

 Pedal powered system can be used to recharge your cell phones, laptops or to power your camping outside. This is just a start but in future if it gets implemented in local exercise parlor and in every bicycle in a optimized way , it can produce electricity on large scale. Moreover , this method used successfully in recent wall street demonstration.

Things to know : 

Alternator : An alternator is an electromechanical device that converts mechanical energy to electrical energy in the form of alternating current.

Alternators generate electricity using the same principle as DC generators, namely, when the magnetic field around a conductor changes, a current is induced in the conductor. Typically, a rotating magnet, called the rotor turns within a stationary set of conductors wound in coils on an iron core, called the stator. The field cuts across the conductors, generating an induced EMF (electromotive force), as the mechanical input causes the rotor to turn.

Inverter : An inverter is an electrical device that converts direct current (DC) to alternating current.

Real Time Sorting Machine

It is Candy sorting machine built in LEGO. It is using Java Optimized Processor which is mounted on LRBJOP board.It is using tilt-tray sorter method.

Why Real Time Sorting used?
A tilt-tray sorter is a high-speed, continuous-loop sortation conveyor that uses a technique of tilting a tray at a chute to slide the object into the chute. It is used to expedite the process of Order fulfillment to consolidate line items of an order, and to process returned products for immediate updating of inventory in real time.

Helpful Resources : 

Java Optimized Processor :  
The unit controlling the LEGO motors and sensors is Java Optimized Processor (JOP). JOP is a Java processor, an implementation of Java Virtual Machine (JVM) in hardware.JOP executes Java Byte-code with precise timing constraints for each instruction, enabling execution time and scheduling verification.
Click here for JOP Design website

Uppaal :
Implementation has been modeled and verified using Uppaal. Uppaal is an integrated tool environment for modeling, validation and verification of real-time systems modeled as networks of timed automata, extended with data types (bounded integers, arrays etc.)

Lego PCB : 
LEGO PCB is a robotics invention system of the LEGO Group. It was intended for children, but it turned out to be a great toy for adults, too. It combines electric components like sensors and actuators with Lego bricks and Lego Technical parts, such as gears, wheels and axles, to build robots and other automated or interactive systems.

Escalator Compatible Wheel Chair

People who use Wheel Chairs , always face difficulty using escalators. Students at Illinois Institute of technology find solution of this problem by designing this chair in different way. Wheel Chair developed by them can be used at escalators.

Mini Scooter

Mini Scooter is good and practical project for mechanical students. Moreover, it can be build using the materials which are available easily.

By building scooter , you will understand the how it works and also what are the difficulties engineers face while building two wheeler. I would suggest you to go one step further by building it green. Green means scooter which runs on compress air or solar or any form of energy which is less polluting then existing one.

While building this project , I would suggest you to focus only on its functioning and less on looks or its design malfunctions. Because designing is altogether different field , it needs different approach and time which we can do later after building our mini scooter.

Things to consider:

Estimate cost and a profit feasibility
It should be light Weight
Safe to ride

Components Required:

1. Power
2. Engine
3. Chassis and
4. Controller

This project is based on very simple concepts of mechanics, and it is easier to understand if we start from tail. For example, to rotate a wheel, we need engine, in this case Two Brush-less DC Motors . These motors need to be controlled by controller, in our case, it is two power MOSFETs Rectifier (IRFB3207 and IRFB3077). Moroever, to power these motors, we will need some form of energy and here we use electric power stored in batteries. You can use as many batteries as you want.

Income Tax Calcuator

How this tool would be helpful?

Income tax calculator is very useful tool for every day users. Every one of us need to calculate our payable tax each year. This task become much more complicated when we have different sources of income and each has different rule from income tax department.

For Whom : This project idea is for Computer Science(CS) and Information Technology (IT)Students.

Level : Easy

How to build it ?

As always to build any software project , we will follow water fall model as you have studied in Software engineering class :

Requirement Analysis :

This is one of the most step for any computer science project. In this step we find out complete requirement for this project including customer's requirement and software requirements. Very important questions such as Why we need this particular project? Who are end users? Things like that should be answered in this step.


We will database to store user information, tax rules information and stuff like that. For this project we will use Mysql as our database engine.

Which type of Application it is going to be?
We are going to make it a web application because this application needs regular updates about the IT rules and if we made desktop application , it would be extremely difficult for us to update the database of each and every customer.

With the help of web application users from different countries can use it without worrying about updating it manually because administrators of this application would keep on updating and adding new rules whenever applicable.

Programming Language:

After knowing that it is going to be web application it is easier to decide that it is going to be php application. There are two reasons behind my selection :
First, PHP is very popular language and free books and tutorials are easily available online.
Second its free, PHP is open source language so that its totally free to use and it gets updated time to time with better functionality.

I have discussed some points for our planning phase but you can add many more details in requirement analysis , because bigger it is , better your software will be.

Design :

There is going to be two sections for our income tax calculator :

Administration Section : Owner of the application can edit the income tax rules and modify the data such as rates which is necessary.

User Section : Where user can select his or her country or state, so correct tax rules can be applied for his tax form. After that there would be income form to be filled ,which eventually gives user total amount of tax to be paid.

You will need pencil and blank papers for this section , draw design of all the pages which are required , draw form , its label , specify where you need text field, radio button or combo box.

Implementation :

Download Wamp server and start working with the help of simple notepad. To code you should have good knowledge of php , read some free tutorials on internet if you don't have that.

Verification :

Software testing can be stated as the process of validating and verifying that a software program/application/product:
  1. meets the requirements that guided its design and development;
  2. works as expected; and
  3. can be implemented with the same characteristics.
There are three types of testing whose explanation is out of the scope of this post but you can read more about them by clicking on links below :

1.White Box Testing
2.Black Box Testing
3.Grey Box Testing.

Maintenance :

Software's are never complete there is always scope for improvement. So, our income tax calculator too needs continuous upgrade for new features and technology.

For your help you can download source code and application itself from the links below :

Income Tax Calculator :

OpenTaxSolver : Open Source Income tax calculator written in C

TaxMagic :A simple open source/free software tax calculator written in .NET

automatic parallel parking cars

What is Automatic Car Parking ?

Automatic parking is an autonomous car maneuvering from a traffic lane into a parking place to perform parallel parking, perpendicular or angle parking.

What's the importance of this topic? 

Parking is one of the challenging thing for humans in Car Driving. Even though , lot of solutions available for smooth and safe driving such as car collision avoidance system, but very less focus is given to the the automatic parking system till recently. Although,many cars are now available with this feature such as Toyota Prius , still there is a long way to go.

For Whom :
Mechanical, Electrical, Electronics and Computer Science , almost all branches.

Level : Difficult
It is not an uncomplicated task to build up automatic parking expertise for a car. First of all, the car must be able to sense the surroundings, to find a free parking space and to detect obstacles in the car park.
Secondly, it should have the capability to plan the movement itself from the input of sensitivity system.
Lastly, it should be able to go after the premeditated motion sequences and to make sure that a goal position is reached, regardless of noise and errors.

Renewable energy projects

I got many emails from many readers regarding renewable energy project ideas. Even though, I had given lot of projects related to solar ,wind and wave energy in Mechanical engineering projects post , I still receives many queries regarding this.So, I have decided to write more about this topic in detail.

Due to scarcity of natural energy resources on earth engineers need to develop technology beyond them. They are working on it from last many years but by now global warming and oil prices are hot topic. There have been lot of big conferences around related to it. Many big companies took initiative and got some success too. Car Market has flooded with hybrid and electric cars. These cars not only sleek in design but has power which is no short of gasoline or petrol.One of the best example for these cars is Toyota Prius.

In my opinion to win against global warming and oil bills ,Government should adopt three way approach :

1. Start investing in research work related to renewable sources.

2. Improve efficiency of current machines.

3.Make people aware so they start saving energy as they save their money.

To implement two of the above three points , government would need engineers like you, so its better to build projects on renewable resources in your final year.I am giving you links having details about these projects :

Pedal powered refrigerator

The purpose of the bicycle powered refrigerator is to allow someone to take a bike trip and keep their food or drink cold. This project can be used for poor neighborhood of Africa or Asia where electricity is still a distant thing . Moreover it can be extended to more useful device with the help of windmill or flowing water . If its pedals joined with the turbine revolving using wind or water, we can use this refrigerator as a automatic machine . This project idea is for student of mechanical , electrical and physics students.

Concept :

When we pump out gases from the water box in the refrigerator by paddling a bicycle , we creates low pressure area inside the box, due to this low pressure ,water starts evaporating, and for that evaporation it needs heat from the surrounding which is our refrigerator.In that way it cools our refrigerator.

Steam is generated in the process of evaporation which later been absorbed by Zeolite as shown in video . Absorption of steam is a property of zeolite that's why we use it in this experiment.

What are Zeolites ?

Zeolites are microporous, aluminosilicate minerals commonly used as commercial adsorbents.An example mineral formula is: Na2Al2Si3O10·2H2O, the formula for natrolite.The major producers in 2010 were China, South Korea, Japan , Jordan , Turkey ,Slovakia and United States. The ready availability of zeolite-rich rock at low cost and the shortage of competing minerals and rocks are probably the most important factors for its large-scale use. You can purchase it from any mineral supplier in your city. Just google it with your city name.

A collision avoidance system is a system of sensors that is placed within a car to warn its driver of any dangers that may lie ahead on the road.Ford announces new radar based collision avoidance system.This project idea is for Mechanical , Electronics and Physics students.

Hydrogen powered vehicle

Hydrogen Vehicles use energy produced by fuel cells. A fuel cell is an electrochemical cell that converts chemical energy from a fuel into electric energy. Electricity is generated from the reaction between a fuel supply and an oxidizing agent.This project idea is for mechanical and automobile engineering students.

RC Helicopter

In the past I have discussed Project Ideas related to RC Planes and Cars, Yesterday I received a mail asking me about information related to RC Helicopters.These helicopters also known as Radio Controlled Helicopters.They are toys which can be controlled using remote control.Building them help us to understand the concepts of real helicopters and their flying.This project is for Mechanical , Aeronautical and Physics students.

Solar Powered Air Conditoner

Air conditioners are both cause and solution of global warming, due to rise in temperature in recent years, it becomes necessary for each one of us to have air conditioner. It has become very important part of our life in recent years. The only problem is that it consumes great amount of electricity which results is more global warming.

One of the best solution of above problem is air conditioner which do not use electricity generated by pollution generating fuel, instead use something renewable and unconventional. One of the example for that is Solar Powered Air conditioner which takes its power from solar.Solar air conditioning refers to any air conditioning (cooling) system that uses solar power.

This project is part of solar project ideas and can be used by students of Mechanical  or Electronics engineering. Even students of Physics would find it interesting.If this project is implemented with Passive Solar Design , it would be more effective.

Sun Tracker Project

Solar energy is the most powerful resource that can be used to generate power. So far the efficiency of generating power of solar energy is relatively low. Thus, how to increase the efficiency of generating power of solar energy is very important.

According to Wiki A solar tracker is a generic term used to describe devices that orient various payloads toward the sun. Payloads can be photovoltaic panels, reflectors, lenses or other optical devices.It is used to minimize the angle of incidence between the incoming light and a photo voltaic panel. This increases the amount of energy produced from a fixed amount of installed power generating capacity.

This project idea is for students of Mechanical and Electronics engineering. Moreover , students of MIT have won prize for the same.Cleveland State University students has done project on sun tracker in 2008.

Fluid Mechanics Projects

Fluid mechanics is the study of fluids and the forces on them. Fluids are liquids, gases, and plasmas. It influences everything from aircraft and car performance to blood flow and breathing.Most of fluid mechanics projects depend on formula v1p1/t1 = v2p2/t2, which states that pressure and volume are inversely proportional while temperature is inversely proportional to both . Wayne State university has one page dedicated to word files(downloadable) related to fluid mechanics.Most processes that converts energy from one form to another depends heavily on fluid mechanics

On the Website of Technical University of Denmark, they have discussed an assortment of projects connected to it. If some of you are interested in demonstration than you can visit Wolfram website Demonstrations.

Fluid mechanics projects attract sponsors too. This field is very pertinent for Automobile, Aircraft and Space research organizations. Moreover , list of IIT Madras sponsored projects  proves my point.

Wind is the flow of gases on a large scale.Wind can play important part in our growing energy needs. many European countries as well as Asian countries such as India , started to invest heavily on windmills.

Cogeneration Project

Cogeneration (also combined heat and power, CHP) is the use of a heat engine or a power station to simultaneously generate both electricity and useful heat. We all know that all power plants emit heat while producing electricity, this heat energy can be used for other purposes. Masnedø CHP power station in Denmark(Image shown below)  uses the same concept.In my opinion it is a great project for Mechanical Engineering students.Its use is not only limited to big power plants, it can be used in other places too, good example of that is: implementation of co-generation plant at Carnegie Mellon University about which you can search on internet.

At the time of global warming ,it is vital to improve efficiency of  our power plants,this can be done easily using this method.University of Gaziantep journal about Performance assessment of co-generation plants proves my point.
Coopers' Brewery uses this system to reduce its carbon footprint to 50 percent and at the same time double there production.

How cogeneration works ?

Even though companies started to implement co-generation in their plants , there is still lot to do in this field,for example there can be other ways to use this heat or how many other places this concept can be implemented.

Vacuum and Power Brakes

Vacuum brakes are one of the oldest braking system exist. It was first introduced and employed on the trains in the mid-1860s. The most simplest way to explain it is that it uses vacuum power to stop the train. These brakes have been improved significantly over the years.

Vacuum or power brakes are used in all most all the railways and modern day cars. It consists of five major components:

1.Break Pedal

2.Intake Manifold


4.Hinge and


How Vacuum brake works?

This system has two chambers, one is always filled with vacuum(first) and other one has either vacuum or atmospheric air(second). Their is a link between two chambers, so vacuum can transfer from first chamber to second.

When we push the break pedals, it opens up the second chamber seal, which allows atmospheric air to enter into the second chamber. This air exerts lot of pressure on the first chamber filled with vacuum which eventually push the brake fluid and stops the vehicle. I am embedding very important video which will help you understand exactly how it works.

This project is good for the case study purpose.I am giving you some helpful links below  :

Heat transfer Projects

Introduction :

Heat transfer is a discipline of thermal engineering that concerns the transfer of thermal energy from one physical system to another.

Pneumatic projects

Pneumatic is a branch of engineering, which deals with the study and application of use of compressed or pressurized air to affect mechanical motion.This technology use energy produced by compressed air engines. Projects on Pneumatic are both productive and informational.

Air powered bike

I get this idea from Planet Mechanics show of National Geographic Channel . I have embedded a clip of that show below. This project uses a similar concept as of air cars because both of them use compressed air as a fuel.

Concept :
In this project we compress gas into a cylinder. Compress air behaves like a spring,. more it get compressed, more force it generates. We can use this force for doing any mechanical work and most of the pneumatic projects use this concept.

How much it cost ?

It would not cost much if you have old bicycle and one cylinder in a scrap. All the other items such as engine (Which can be unrepairable motor pump  ) , pipe , valve are cheap and easily available in market.

How its work ?

Its upon you , how you want to use compressed air energy , but I suggest you to use old piston method which was used in steam engines, only difference is, here we use compressed air to push the piston downwards as shown in Video :

Basic Wood Lathe - Cutting Beads and Coves

Compressed Air Cars

According to Blacksmith Institute Toxic pollution poses health risks to over 100 million people. Moreover with the rising fuel prices there is potential demand for alternative fuel vehicles.Keeping that in consideration french motor company MDI started to build air cars.Even though it is a new concept and there is space for large amount of experiments in this field, Companies started production of cars based on this concept as shown by Sun dial list of 2010 air cars.

School Websites

This project is for students of Computer Science, Information Technology and MCA. It will help you to get understanding of real world requirements and implementations.In this post we will take hypothetical example  "iproject ideas school" and discuss how to code it. After understanding basics you can build any website related to schools.

Start with Requirement Analysis :

5 dynamic web pages which can be updated by school staff on regular bases.These 5 pages are home,news, contact us, feed back and login page.

Dig deeper into requirements  :

1. Home page :  Welcome page for visitors : some basic information about school.

2. News page : This page will publish news about new happenings in school.

3.Contact Us : School address and phone numbers

4. Feedback : It will have form to get feedback from users

5 Login Page : This page will be used by teachers to login.
Back End (Databases)

Database Name : iprojectschool
Pages_Detail : Page_id of type int , Page_Name of type varchar(50) and Page_data of type text
Login :  User_id of type int , Username of type varchar(50) and Password is of type varchar(50)

I think above requirements are sufficient to build basic and easy to understand website , if you want you can scale it up.

Coding Part :

We are going to use PHP and Mysql.I am coding in PHP but logic is same for all other languages.

Software Requirements :
You will need : PHPMyadmin , Apache Server  ( Learn how to install php ).

 Before writing any code, it is important to know that, what we are going to do?

We will design admin page to display and update our database tables.(For this example , we will use phpmyadmin)

We will design home page of school.

That's it.some of you argue that what about the other pages? Our home page will handle all that stuff. I will explain you how?

Step 1. First of all, create database using phpmyadmin. If you don't know how? click here to learn.

Step 2. Insert some data for our pages with the help of phpmyadmin.

Step3. Then create directory of iprojectschool in our root folder such as htdocs

Step4. Create new file home using notepad and save it with php extension.  Now open it with notepad and paste database connection strings into it.

Step5. Type the given code into your file.

Step 6. Create login with the help of this site.

Step 7. Create feedback form

Most of the things that has been covered in this tutorial are for education purposes and not for commercial use,still if you need any help. leave comment. Purpose of this post is not to spoon feed you but make you think. You can't complain that there is no css associated with it or I have not discussed security with you, I left them intentionally for you.

I hope it helped.
