ECE 4760: Introduction to Microcontroller Programming FINAL DESIGN PROJECT
May 10, 2009 11:06 AM Subscribe
Our project is a fart intensity detector which ranks fart magnitude on a scale from 0-9 according to sound, temperature, and gas concentrations. Two Cornell EE students built a Fart Intensity Detection Station as a final project for Introduction to Microcontroller Programming.
"It is a fascinating idea," say Robert Clain and Miguel Salas, "that something that induces so much laughter in society can be actually measured and objectively ranked. In fact, it is a project that shows the world out there that electrical engineering can indeed be simply deliciously FUN!"
...oh god I can't believe I'm posting this. Sorry. And you're welcome. Enjoy the tags and the header picture.

but what about smell? can they measure a plain stinky fart against one that makes everyone's eyes water?
it don't mean a thing if it ain't got that sting

In all seriousness, I think they should have ranked in accordance to relative humidity as well.

From the syllabus "The purpose of this course is to enable its students to carry out sophisticated designs of the modern digital systems which now appear in products such as automobiles, appliances and industrial tools. The basis of such systems is the microcontroller, a microcomputer optimized for single-chip system design by possessing many peripheral devices geared to real-time applications. The microcontrollers we will use are the Atmel MEGA series RISC microcontrollers."
So they're preparing engineers to turn out sophisticated designs. And yet this project's code is somewhat amateur. A main loop with an if(a)-if(b)-if(c)-if(d) begging to be turned into a switch statement, and a complete lack of interrupts.
but what about smell? can they measure a plain stinky fart against one that makes everyone's eyes water?
They measure odor by way of an H2S sensor. This post would have been greatly augmented by the video wherein they describe how it works.
Other class Final Projects appear to be equally if not more nifty.

I'm a CompE, which is basically half CS and half EE. I loved it, I learned a bunch of CS (operating systems, etc) and EE (DC, AC, grid, etc), its a shame I never really had the opportunity to apply it. The closest I got was retrieving data from a CS1000 datalogger for solar power... now I spend most of my time doing web development.

Those aren't the things I judge farts on, I use...
Volume, ie: sound intensity not amount of gas
Hang Time, how long it lingers
Taste, it can't just smell bad bud it has to leave a bad taste in your mouth

We choose to measure the fart in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win, and the others, too. It is for these reasons that I regard the decision last year to shift our efforts in fart measurement from low to high gear as among the most important decisions that will be made during my incumbency in the office of the Presidency.

If you could somehow create a user interface for this device that would display an arrow pointing to the originating asshole person, THAT would be awesome! No more "Who farted?" discussions would ever have to occur again. Of course, you'd have to take into account micro-climates, air movement in the surrounding area, etc. But it would STILL be awesome.

For purposes of detection who dealt it, I suggest multiple sensors and calculating the gradient. It would probably require something more sophisticated for testing purposes.
Or looking back at scenarios in my life, it's probably sufficient to just instrument a car's seat cushions.
