Richardson combined a couple of Arduino circuit boards with an infrared LED light -- that little red bubble on the front of your TV remote -- and programmed the whole thing to interact with a TV's closed-captioning system.
The DIY gadget reads the closed-captioning transcript as it's aired and then automatically mutes the television for 30 seconds when it picks up certain words.[...]
As long as that person's name keeps coming up, the remote keeps muting the TV. The first time he got it to work, Richardson said he "was in silent bliss for that 30 seconds I didn't have to hear about Kim Kardashian."
