i just don't get the idea why you guys keep on asking for money..

well..,, i've got few more question ..

how about the possibility of combining it with video, audio, and signal that controls the turning off and on of the devices. Is this possible? does this affects the video or audio signal? and one more thing.. For you, how hard is it to build a project like this? [very easy,easy, hard, very hard]

thanks again .. hope its free coz this are just questions not complete applications..!!!
