Arduino Fart-O-Meter

Jerome — Thu, 17 Feb 2011 06:22:39 +0000

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!

It’s already featured on:

Hackaday.com http://hackaday.com/2011/02/16/arduino-fart-o-meter/

and Solarbotics.com http://www.solarbotics.com/news/2011/02/ex-interns-and-their-projects/!

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.

And here is the receiver. The servo motor simply points to the fart intensity on the white sheet of paper.

Those are nRF2401A Transceiver with Chip Antenna (Sparkfun sku: WRL-00152). Pretty small and easy to use with the Arduino. There is a library for those modules.

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)

Halloween in Hong Kong

Hey!

I was lucky enough to be in HK for Halloween! It was insane!

Why am I wearing this costume of “NO PICTURES”? Here is a hint:

They are everywhere! They made me fell like a STAR!

Check out this awesome panoramic pictures taking with my Sony camera! It is photoshop to make it clear and nice (ok not really).

I have uploaded all those pictures on my flickr account. You can see the set here http://bit.ly/brtmqC

I also made a instructables for fun on how I made my costume. You can vote for it too.

I explain everything about my story on how I got the idea.

I also meet those awesome yoyo player from Hong Kong! Yeah, I use to play yoyo like a maniac back in the days. Here is a pictures with the gang. It’s because of them that I when to that crazy Halloween party (twice)!

If they look good, it’s because the guy who took the pictures is a good photograph!!

Battle symet

Here is a other robot I made for Solarbotics instructables. The principal is base on the “symet” robot. Symet stand for symetrical/symmetric robot. You have a single motor where the shaft rest on the ground. It moves in different directions depending of the point of contact around the shaft and the ground. In my case I use 3 wheels and one of them is motorized. When the motor is powered, the entire robot spins in circles while moving foward.

Check out my project I made for Solarbotics. It is a rolling robot inside a plastic ball.
