Well, thank u mosfet and tansis for ur useful advice. As mosfet rightly mentioned, since i am willing to get the scholarship, it is my duty to find a suitable project that i am satisfied with.
Yesterday, i was going through an electronics magazine and found the right catch that is innovative enough and has good applications
(for blind people). The circuit uses a dual reflective sensor. u will get more info when u have a look in the file attached( Its a page from the Magazine).
What do u experts think about it? is it worthwile doing such a project that can impress the panel of judges responsible for the scholarship?
Do write and tell me.
However i do have some queries :?: regarding the circuit like,
1. What happens it the blind person moves into a crowd? we humans do give out IR rays. while using this circuit, wouldn't the blind man get confused which way to go since there are IR rays from all directions?
2. Will the IR rays of sunlight have any effect?
3. Can i modify the circuit by replacing the IR dual reflective sensor with something else that serves the same purpose but is free from the above drawbacks? If so, how?
4. Also, what further research can i do with it?
5. Are there any other applications?
I am still 18 years old and am sure the judges will drown me with such questions :? . Though i have found a project of some importance in real life situations, the above queries are hindering my progress
. Do any of u have some useful advice?Do give a reply. I will be waiting to hear from u experts. Atleast that will build some confidence within me 8) .
Thanks for reading this long mail,
Bye, Surya :wink:
