This DIY hack is gross and funny all at the same time. A guy on Instructables going by Schmidt has posted up a how to on building a remote control that will change the channel on the TV to a random channel each time it detects a fart.
The builder came up with the idea 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. Using ingenuity and a love for flatulence the guy cobbled the two together.
Now each time the builder’s dad busts a groupie, the TV turns to a random channel. That is a great gag for sure. The parts list includes a methane sensor, Arduino, and a few more items. This would be funny, but my kids would fart on it on purpose.
