Hey, I am back from Hong Kong and here is my lastest project for instructables. I made that thing in less then 13 days!
Yes you read “arduino” and “fart” in the same sentence!

This video will explain everything!
Here it is mounted on the chair directly. It is wireless!
This is the emitter on the chair. That is a barebone arduino.
I had a lot of fun playing with the MQ-4 methane sensor. The black thing around it is a protective sleeve that I ended up not using. Those suckers heat up and consume 175mA! There is a little heater inside. The moment gas is present, it evaporates and change the output voltages! Fun to use but hard to test… I always had a hard time to try to fart on that thing, I could not fart on command. It’s only when I disconnected the sensor and Arduino from my computer that I started farting like hell! I was piss because it takes up to a minute to heat up and be ready to use. (btw, you can use the butane from a lighter to test it. There is less joy)
