We get to see many discussion forums across the internet in many different languages. Their main purpose is to provide platform to the user for discussion. These forums are not only useful but they are extremely successful.You can imagine their success just by the fact that , it is difficult to find a single person who do not use them(either read or participate) once in a month.

In this post we are discussing about three most famous forum coded in different computer languages.You can download them from their respective sources.

MetaSearch Engine


Meta search engine is a tool which send user request to multiple search engines and get the best result out of it. For eg if you search in meta search engine , it will send your query to various different search engine such as google, bing, yahoo and bring back the best result from them.

Meta search engine project

To build your own Metasearch engine you will need following class :

1. A regex class : It can be used to quickly parse large amount of text to find specific character pattern.
2 WSDL files of search engines and license key : Provided by search engines with key which is free
3. Program for interface.

Perpetual motion machine



What is Perpetual Motion ?
Perpetual motion would occur in a device or system if a motion, once started, were to continue indefinitely.It is believed to be practically impossible because of friction motion can't continues indefinitely without any external source of energy. Moreover, it is against the law of conservation of energy, so it is virtually impossible to build such a machine.

Yes, on paper it appears possible, but when implemented practically, system starts losing energy gradually and it gets stop after some time.

If it is impossible why it is important ?

It is very important concept to learn and study because it helps us in understanding energy reuse method and concepts. Though it does not run for infinite time but yes, it use lesser energy than any other system.

Concept:

This system use gravity or metallic energy to move the system. In one of the most common method of these machines, they keep on side of the wheel always heavier, either by water or by transferring some kind of weight. This heavier part keeps pushing wheel downward with the help of gravity and this machine should remain in motion but in real life, it starts to loose energy and eventually stop.

Propeller Monorail Student Project


As its name signify in itself, monorails are trains which runs on a single track. I thought of discussing with you because recently in Mumbai, India. Government decided to use it for public transportation. Though this technology is not new but I got excited to discuss the possibilities it brings when we think about elevated monorail. This is going to be very helpful because they will need less space and can be used at the middle of the road i.e divider.

If you consider monorail as one of your project, that the best thing is that you can power your engine using any source you would like to use. For example electric engine, diesel engine or solar powered dc motors etc. These trains are commercially used in Japan and they are very successful too. Moreover, technology adapted in maglev trains has also come from these trains. To build monorail project either elevated or on ground, you need to found how you can innovate it in such a way that it brings something new within your work. In my opinion, as a student, you will find ground trains are easier to build but I before jumping to any conclusion, I would like you to do lot of research and find each and every minute detail about how you can build this for yourself.  I have shared couple of links below and I hope you will find many of them useful.

As far as the student project is concerned, monorail has lot of potential as shown by the Students of Australia as they used monorail for their final year project. The best thing they did is to use other components with this train to make their project stand out from other student's work.

Their train not only follow the line as line following robot  but it is smart enough to stop at various stations.

Automatic light control

In present scenario where energy costs us both environmentally and economically, it is wiser to save electricity. Automatic Light control can helps us to serve  our energy saving purpose.Moreover, we can implement similar idea on something very useful such as Automatic Traffic Light control System.This project is for Electrical and Computer Engineering
students.
