Optical Character Recognition

What is OCR ?

Optical Character Recognition is a process of extracting text from images. You have noticed that whenever you scan text document ,you can't able to edit it with the help of text editor but with the help of OCR you can do it


This technology is very important not only for editing scanned documents but for the future of automatic cars.To make a automatic driven car , car should have capability to read instructions written on the street.Moreover, this technology is used by search engines to read what is written on images.

Even though, many believes that it is a solved problem, I don't agree with them.You would not agree with them either after using some OCR software because they still not giving perfect result.

iphone application ideas

Why we need to develop iphone applications ?

Apple has become most valuable US Corporation surpassing Exon Mobil with market cap of $331 billion on Wednesday. This is not the only reason for developing iPhone application.

After a staggering 20.34million sales in quarter 2, Apple's iPhone has been confirmed by the IDC as the worlds' biggest selling smart phone. The smart phone market is expected to grow by 55% in 2011 and with iPhone 5 is soon to be launched,it is going to be apple devices everywhere.

With that many users there is need for more apps, it ranges from education to business, commerce to art, books to newspaper everything you can think of.



How to develop apps for apple devices?

Before going any further, some of you may ask that how can I develop app for this device. To develop iOS applications, you use Xcode, Apple’s first-class integrated development environment (IDE).Moreover, you need to learn about objective-C which is extension of ANSI C.For a start you can refer to the ios developer library. Later you download Iphone development guide course of Stanford University from here.After which, you can purchase Beginning iPhone 4 Development from apress.

Project Ideas :

Abacus : We all know abacus is very useful device and if you can develop virtual abacus for kids it would be great help.










Cross and Round Game

Sudoku:














Paint : People love to paint, no matter how many existing programs of painting, there is always room for improvement.

Blogging platform: like wordpress.org : You can develop blogging application, where user can make account and write blogs easily.

Currency converter : It can be used while traveling. People often convert currency to native one.

Scale Converters : Like Meter into kilometer

Business App : Stock Exchanges, Gold Silver Prices, Favorite Stock Details on the Go.

Astrology App

Voice Recognizer Calculator : Calculator which recognizes your voice commands and gives audio answers.

Website Reader for Blind People

Voice to Text Notepad :Where user can note down information using his voice.

There can be lot more ideas, its up to you what you really like. For engineering students of Computer and Information technology ,any of the above project would do be suitable for final semester project report.

Vocabulary Flash Card : Build application related to improve vocabulary of its user ,not only in english but in other languages such as french , spanish or greek.

If you have any idea which you wanna share , please mention it in comment section.

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 :

Projects:

Solar Cooker
Solar Powered Mobile Charger
Solar Toy Car 
Solar Powered Refrigerator
Solar Chimney
Beam Circuit Solar Engines
Solar Powered Path Finding vehicle
Solar Powered Generator 
Solar Insect Robot
Air Conditioner 
Wind Mill Power Generation System
Hydropower Projects
Generate Electricity from Dance Floor
Perpetual Motion Machine 
Pedal powered refrigerator
Pedal operated power Generator 
Power generation using wind turbine kites
Air Compressed Cars 
Air Bike 
Build Electric Two Wheeler Bike
Generating Electricity from Waste Water
Solar Powered Water Pump which can be used in drip irrigation.

Other Sites :

Using an Alternator in Renewable Energy Projects : An alternator differs from a dc motor in that it contains no permanent magnets. Instead, there are two concentric wound coils of wire.

Solar Electric System : Good blog has all the details regarding regarding this system.

Montana State University : This site discuss about some of the costliest projects. To work on these projects you will need private or government funds.

Solar Water Heating Installation project : Students of Stanford University has been working around campus area for implementing some useful solar and wind energy 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.

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.


These helicopters can be used for :

Spying Purposes (With Camera)
Fire Fighting ( Give us details of exact location of fire)
Traffic Details ( Fly up and record traffic information)
To spray pesticides in the field.(Chinese people using it)


Final Project RC Helicopter ( Complete Detail)
