මේ බ්ලොග් අඩවිය ලිවීම මම නවතා ඇති අතර, මාගේ පවත්වාගෙන යන බ්ලොග් අඩවිය වෙත පහත සබැඳියෙන් යන්න.

මීට අමතරව මාගේ අනෙකුත් බ්ලොග් අඩවිද පරික්ෂා කර බලන ලෙස ආරාධනා කරමි.

Our new community site for materials engineers and students is now up and running.
many things to get from it. and many facilities too.


Materials Freshers’ Night is here. August 20, 2008

Freshers’ Nite of the department of materials Engineering will be held on 2moro, that is 21st of August.
I and my group designed the Souvenir for the occasion. Below is the front cover, its a design of mine.

“Imagination Engineered” is our theme for this year.


Our Project – Safety Plug May 22, 2008

Electronics… It has changed the way of life of the human beings ever, after the great invention of the “transistor” and the developments made thereafter. Nowadays almost everything from watches to huge airplanes we use to travel through the world is controlled by computers which ultimately beg the help of electronics to make the hardware for them.

Electronics creates what we want. But it doesn’t make products itself. So we have to design,
implement and maintain the products, though they make our lives easier. We have to treat the products we use to be the way it should be. Simply we have to treat them carefully within their specifications. As human beings we do faults and sometimes are absent-minded. So sometimes the products we use, electronics or electrical, get their lifetime shorter because of the faults we do and the absent-minded usage. For an instance, say that we have been using a soldering iron for an hour without disconnecting it from the main power. But there is a limit of heat and time which counts for the lifetime of its element. Say if it’s a hotplate of a kitchen which is turned on for more than 1 hour may actually end its lifetime and same as for a water heater which will be burnt if all the water is vaporized and the heater is still turned on. Above are the common faults we do when using electronics and electrical equipments in our day to day activities. But they do severe damages to the products. Therefore we have to deal with them carefully while keeping our lives safe. If we have a product which can indicate us that the product is being used for a certain amount of time and it is still turned on, then it will help us to prevent the product being overused. So that it will longer the lifetime of the product and sometimes it may keep the safety of our lives. If a product is overused and it generates much heat, it will probably blow or make a fire which will entirely put our lives in danger. So a product which keep us informed as described above about the product we are using will be much helpful for our lives and it will exactly make our lives easier and safer with products we use for our day-to-day activities. It is really a ‘Safety Plug’. We will call our product hereafter the “Safety Plug”.
