Sensors


Ongoing photsession for the presentation on LTH webpage. With Josef!

A short test on how sensitive a piezoelectric element on a membrane is to touch. Sensors like these can be really interesting on a structure to control the shape of it.

This is Josef, shaking and swinging an accelerometer which I´ve hooked up to speakers, through the Arduino again. Accelerometers can be found in many mobile phones, in Wii-controllers etc, telling what´s up and down, how fast something is moving, and so on. Hope I´ll hang this up in school tomorrow. Enjoy the clip.

My tests turned out a bit differently then planned. I was thinking the Arduino was able to play sound on more channels, but I was able to experiment some with stereo effect and position. Through these experiments  I´ve learned alot about  programming. It´s easy to program with sound because it gives a direct answer if you got it right. What you want is the right response, the right tone for the right duration. 

I can easily imagine the speakers being replaced with other things as some responding motion, bending or moving walls etc. Unfortunately the public test or exhibition will have to wait til next week.

 

 First experiment is the ultrasonic sensor reading distance into the arduino wich aoutputs different two tones for different some different ranges.

Second one uses two speakers. The ultrasonic sensor is on the same side as one of them and closing up to that one, sound moves over to the other side and vice versa. Standing in the middle both speakers give a tone.

Thank you Martin for walking back and forth.

This is a project by students at AA, Inter 10, Run by Ecologic Studio.  702-P-48-20090825075435

It´s interactive in a very direct and beautiful way I think, since you, by your weight, move air from undernetah you into a structure to generate movement.711-P-48-20090825082044

Since I was imagining something more or less exactly  like this (but maybe not that complex..) with my balloonexperiment I was staring in the beginning of this week, I was a bit sad it was already done. Anyway, Ricardo showed me this project and it was very interesting to see this, so I posted it on the blog. Think I´ll continue my experiment on monday to see if that turns out differently.

Trying out my Ultrasonic Range Finder I managed to build and program(very much copy and paste) my first interactive device. The range controls a servo, which was strong enough to bend a piece of plexi.

…and I put it on my Youtube-account!

Found this interesting video on my daily morning-scan of Youtube.  Anything tranforming I make I will have to think about the energy used to make it move or respond. This Super Cilia Skin seems interesting for ideas, not only for sensors but as power source.
