Ever get the sensation that those TV talking heads are caught in an endless loop of mind-assaulting rhetoric? You can now prove it through a trusty Arduino and an instantly updating word cloud. Nootropic Design rigged up a homebrew hack that connects your TV tuner’s composite feed to a Video Experimenter shield that decodes the closed captioned NTSC broadcast. A Processing sketch then takes over and builds an alphabetized, dynamic metadata cloud you may view to your computer’s screen. This system enlarges words in keeping with frequency and omits those shorter than three letters. As you will discover inside the pic above, commerical time during NBC’s Nightly News skews slightly… older. Look into the video after the break for a large Bang Theory version of this word-building project.
