Last Year's Winning project

GADGET-2K7 :

Today we are seeing a number of PDAS’s which are helpful in coping up with the busy office life. In the abstract we are going to present an idea how a ordinary mobile [like a 2600] can be remodeled so to facilitate many more applications such as controlling a house-hold item such as a fridge or a ac. .., It does not require any circuitry as the signal from the cell phone goes via a phone call .

Also the other feature of the cell phone is the solar charging of the Li-ion battery which can be done in the similar way as such a dual powered calculator works.
The most important of all is the sending a picture message from a cell phone like 6600 to a mobile which does not have an mms capability like a 2600 this can be done using image processing technique.

Quiet important feature of cell phone is the self charging feature of cell phone which is theoretically possible as there is a loss of sound energy when we are speaking through a phone.
It requires just a transduction part after which it can be coupled with the solar charging part of the cell phone .

After taking a overall view of the new age common man’s cell phone it can be said that all of the above features can be manufactured on large scale .The weight of the cell phone may go a few grams up and the cost may increase over
Just a hundred rupees more……………!!!!!!!!!!!!!!!!!!!
