Pneumatic Playground - Week #5

11/14/2016

 

Summary:

A couple of breakthroughs this week: The first breakthrough had to do with controlling the deflation rate, a problem that has persisted throughout the project. Our plan up to the weekend was to create different flow channels with incrementing openings, but with a piece of fabric and how much you compress that fabric in the 1" deflation chamber does the job as you can see in the video, where the inflation rate is the the same as the deflation rate.

To the left you can see the new setup, basically eliminating multiple breadboards and jumper wires that has been bugging us.

Also as you can see in the video below, Thierry programmed multiple buffers so that every segment of a recorded buffer will store separately (up to 30 buffers). This way dynamic buffers will inflate in separate balloons and deflate their associated recorded segments when activated. ​

Pneumatic Playground - Week #2-4

11/8/2016

 

Summary:

Three MICS setup around the lab. Any speech in the room directly inflated a 9' weather balloon. Sections of speech gets stored in a buffer. When the balloon is in idle mood, buffer is on delay, sounding as if there are lost voices stored in the balloon. As of now when you hit a switch the balloon will deflate spilling the contents of buffer at first from inside the balloon (with speaker setup inside) and slowly ramps to the second speaker directly above where the ballon chamber spill. Please see video below for a bit of clarification.

Deflation Experiments
Due to the rapid rate of deflation, not enough time is provided for the buffer to spill enough speech that becomes interesting. We tried outputting through 4 empty pneumatic valves but were not successful as the openings of the flow valves proved to be too small. This failure led to an important finding:
  • Inflation based on pressure does not rely on the size of opening since pressure is constant
  • But for deflation, separate valves with various openings need to be consistent to create range

Week #1: Quick Summary

Simple switch and potentiometer for controlling the valves.
For the first week of pneumatic playground, me and Thierry hooked up a separate balloon, with discrete inflation and deflation. After powering up the pneumatics, we made a couple of circuits to be able to control pulsating the on/off inflation switch. The following week, we'll be actually embedding a series of these valves to a surface so we can play with deformations caused by the balloons on the surface of tensile structures. First a simple switch and then a potential meter. You can view the experiment below:
