The title just sound to gross but funny at the same time. It so happen that a person from Instructabbles posted a remote control device which is fart sensitive. He enjoys watching his father enjoys farting while their television changes channel.
This idea reached the mind of the inventor after seeing a hack using Arduino to turn a TV on and off using a brainwave headset and an office chair that twittered each time the user farted. He combined the two and come up with the DIY fart detecting remote control. A remote control that will change the channel on the TV to a random channel each time it detects a fart.
The machine includes a methane sensor, Arduino, and a few more items. Just wondering how to test this thing before buying? Well, somebody should fart for sure.
