W. 16 propose a final project that integrates the range of units covered
define: what, where, how, when…
by digital design + digital fabrication + electronics + programming

My project is:
An acoustic Panel that could transform at a certain level of decibels from a flat piece in to a tridimensional object. This panel will improve the acoustic of a room and will use the minimum space from ceiling.
(as a prototype I will design and fabricate one of the modules in the acoustic panel that at the same time could be used as a lamp).

This week we had to decide what to do for a final project. The first idea that I had was to solve a noise problem that we have at some areas at school. I did not wanted to make something that its dimension used a lot of space from the areas so it had to be a flexible object or an object that could transform.
I decided to experiment with texture, explore the pattern and form of acoustic panels during the assignments (molding and casting and composites) in order to have a more defined idea for the project.
Who’s done what before hand?
With some more research about acoustic panels and movement I found out about some great ideas as the following,
Origami- inspired office design that expands, contracts and changes its shpae (drone) by IAAC students at Barcelona: Efilena Baseta, Ece Tankal and Ramin Shambayati (images from www.fastcoexist.com)
Resonant Chamber Making by RVTR and ARUP Acoustics – “resonant chamber is an interactive interior envelope system that transforms the acoustic environment through dynamic spatial, material and electro-acoustic technologies”. (images from nandishjagad.wordpress.com )
There are different and more beautiful origami designs but for the piece I will explore forms as simple as the the Miura-Ori map due to the easy transformation from a flat panel to a 3 dimensional form. The Miura-Ori map uses a series of congruent parallelograms helping the structure to fold and unfold easily, just by pulling two of the ends and the movement from one fold line produces movement along the other.

Other experiment folding a piece of paper:
I will design in rhino the piece and cut it in to assembly the pieces and try different materials for acoustic isolation, also to define the structure to hold the pieces in the panel, the panel to the ceiling and the electronic components in the panel.
What materials and components will be required?

What parts and systems will be made?
I will made the structure using laser cutting and 3d printing for the hinge. I will use the 3dmilling for the pcb production to make the microcontroller and a sound sensor.
What tasks need to be completed and what questions need to be answererd?
I need to explore the combination of codes, I have use the sound sensor and I have move a servo but I do not know how to make the connections between them.
