thanks for reply...
i have found a lot of projects over web.... but doesn't know which works good which weren't. one more thing i should think here is some schematics posted on web may/mayn't suit for all countries.
about me....
consider as a NULL in electronics.... lol
all i know is making very simple circuits with RC,RL, with some diodes or FET or OPAmp(IC741) etc...,
am thinking of making either a simple FM receiver or a "traffic lights model" with LEDs... don't know what that may cost to me...
if you know any suggestions please post...
