Discussion forums

We get to see many discussion forums across the internet in many different languages. Their main purpose is to provide a 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 does not use them(either read or participate) once in a month.

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

MetaSearch Engine

MetaSearch Engine

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

Metasearch engine project

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

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

What is Perpetual Motion?
The 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 continue 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, the system starts losing energy gradually and it gets stop after some time.

If it is impossible why it is important?

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

Concept:

This system uses gravity or metallic energy to move the system. In one of the most common methods 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 lose energy and eventually stop.

Propeller Monorail Student Project

Propeller Monorail Student Project

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

If you consider monorail as one of your projects, that the best thing is that you can power your engine using any source you would like to use. For example electric engines, diesel engines 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 a monorail project either elevated or on the 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 before jumping to any conclusion, I would like you to do a lot of research and find each and every minute detail about how you can build this for yourself.   I have shared a couple of links below and I hope you will find many of them useful.

As far as the student project is concerned, the monorail has a lot of potentials 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 follows the line as line following robot but it is smart enough to stop at various stations.

Automatic light control

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