This is an awesome project by Matt Richardson, called the Enough Already:
I donâ€™t know about you, but Iâ€™m a little sick of hearing about the same people on TV over and over again. I came up with this Arduino-based solution to mute my TV so that I donâ€™t have to hear about Donald Trumpâ€™s feud with whomever or Charlie Sheenâ€™s most recent rant. Using the Video Experimenter Shield, the Arduino is able to decode the closed captioning transcription track, which is transmitted along with the NTSC picture signal. The incoming text is processed for a set of keywords such as â€œKARDASHIANâ€ or â€œSNOOKIâ€ and sends my televisionâ€™s IR remote control mute command, muting the TV for 30 seconds and then unmuting it (as long as a keyword isnâ€™t mentioned again).
