Enough Already: The Arduino Solution to Overexposed Celebs via MAKE
With a bit of technical knowledge, a system has been hacked together to put the television on mute when a key name of an over-exposed celebrity (ie Kardashian) is mentioned.

If that name is mentioned again in the caption feed, the timer is reset.
