Movable sound machine

111

My first idea for final physical computing final project is to making a sound sculpture, something loud, noisy and annoying people! yes! that is the keyword!

I came up with idea of puppet that using wire to control puppet and this thing link to Modular synthesizer that using a lot of wires to create different sounds.

Users have to make different position to make sound work. So they will make themselves in a weird position if they need to hear different sound or trying to make a song by keep dancing. Here is my first prototype of materials and how things should work.

Next processing, I try to working on accelerometer and put it into max msp. Here is some of idea of how sounds work relate to body movement.

In the video I also try a new sensor. I used pressure sensor and put it in rubber wire. I close both side of wire by using replacement valves then pump air into a wire. So when I stretch wire, air pressure changed then input value will change.

here is a making of stretch – air pressure – sensor wire.

final pcomp prototype

After I tried 5 prototypes of BMP180 pressure sensor(link > BMP180) They worked only first time and keep broken after I put it into tube. I changed to link> MPXM2010GST1TR-ND pressure sensor from digikey as Tom recommended. It worked very well but only one problem, It very fragile. If I pull it to hard, the cord will easily to break. So I changed in last minute to go back to accelerometer. As pictures above, I wired them with a very long length and put them in the tube to make them strong and keep the wire feeling. I decided to use clear acrylic to show all the wires and microcontroller because I love them!!!!

L1050572

I mapped X to EQ(cut off , gain and Q) controller , Y to feedback amount(to created delay) and Z to volume. the user have to keep moving to make the sound work.
