Background:   What started it all? 
What will we do at the first meeting? 
How will we start everything? 
 How will the electronics begin to take shape?  
How will the sound get from the suit to the computer? 
How do you begin to fabricate Les Suit? 
 How do you organize and communicate a dizzying array of great ideas? 
 Ahh, could we see a sketch the electroniques? 
 How do you allow for idea expansion without getting lost in the idea ocean?  
How do you modify the idea list so members of the team know which ideas to spend time on?  
Electronics further defined 


How do you modify the idea list so members of the team know which ideas to spend time on?  

What needed to be done:  

Create a version of the "Outline" that indicated where members of the team should focus their attention. 

What was done:  
Pouring over all previous outlines for all relevant ideas.   

What was produced: 
Yet another, more succinct version of the outline but with a color code indicating where we should focus.Again, thanks so much for your time an attention, 

I hope you are well and look forward to seeing you soon, 

Here is the list se have been working with updated with our most recent "best" ideas: 

Pictures from my last meet with you are attached.  I hope they are helpful. 

I will put things that definitely need your feedback in red.  As usual, all of it is open to modification from you.  I trust and look forward to your modifications. 

Let me know if you would like me to organize or present the information in a way the works best for you. 

Suit design Issues/solutions: 

Use manageable staging: 

- Apply electronics in stages (see below for details) 

- Use the mock suit stage to test ideas 

- Use minimal electronics at first 

- Design the wireless system "as we go" but go with wired until wireless is ready. 

Create a cool looking "skin" to be in: 

-  Blue 

- Color accents  ( Whatever heather wants to do.) 

Sensors and implements need to be interchangeable  

(for repairs or change the kinds of devices for different compositions): 

- Create pockets that various sensors could be slipped into. 

- See the brain dump below for kinds of sensors bobby and I came up with.   

- Would there be pockets for the sensors on the suit or mobile pockets that I could slip the sensors into then snap on? 

Larger implements will need stronger adhering: 

- Stitch Velcro over all the spots where there are implements (including the side of the legs). 

Wire runs will go to one point then go to the amp: 

- Have a sheath that goes around the INSIDE perimeter of the suit so they are protected.  Heather mentioned using "interface" to protect them. 

- They will need to run to a point where they gather in back.   

- See the attached suit diagrams Bobby sketched.  They show ideas on the wiring and wireless design ideas. 

- Discuss placement of wireless unit with Bobby (in mid back so the weight is balanced and can't feel it) 

      - Maybe create a fabric "box' or protected space where the unit and wireless will go and be out of the way. 

Gloves are knit fabric that is loose fitting: 

- Any solution for an inexpensive glove that we could put some snaps on? 

- We discussed using an existing leather pair or making some 
- How about a glove that snaps onto the cuff?  Made of the suit material? 
- Also, how about making  right and left mits that effects/surfaces could be snapped into ?


- I have some old school dress shoes that I would like to transform like I he the gloves that I wear. 

Design a way to integrate my art designs with the sound compositions: 

- Create a snap on  light overlay that can be "programmed" to respond to sensors 

- since his is a bit of a tangent, yet very interesting, I will be trying to think of the simplest thing we could try as a "mock" light thing.  

-Let me know if you come up with anything that is very easy to try. 


Apply suit structures in stages:  (I am just guessing here.  List whatever you think would be efficient) 

 Mock suit stage 1 fabric design structures: 

- Internal wire run 

Mock suit stage 2 fabric design structures: 

- Fabric enclosure for wireless pack 

Effects Design Issues/solutions:   

Design needs to balance form and function: 

Organize thinking about electronics into 2 categories of objects: 

- sound making objects - triggers 

- sound processors 

- See pictures for Bobby's approaches and advance those ideas to create most efficient designs. 

Work on robust wireless system: (list of issues to consider): 

     - Make sure it has enough memory for good throughput: 

     - Study you tube video Bobby and I found 

     - Email the guy about how to modify the arduino system to work the way we want it to. 


             contact info: 

     -  arduino memory configuration  (firmware can be changed) 

      -using arduino with pure data  (fermata) 

      -can xbee transfer firmata data wirelessly?   

      -a way to turn effects on and off 

      -a way to change parameters (resistor type things) 

Apply electronics in stages: 

- use wired system for mock suit and work on wireless design as we go. 

- integrate wireless as we figure out how to do it! but move forward with everything else 

Mock suit stage 1 electronics design structures:  

(I am just guessing here.  List whatever you think would be efficient) 

- contact mics 

- flex sensor 

- test run wires to back area and run snake to computer 

- 1 arduino, 2 usb cables to computer as a first proof of concept  of wireless ideas 

-Mock suit stage 2 electronics design structures: 


Get necessary electronics: 

2 Arduino   (60)   

    1 on suit (no firmata-just xbee)   

    1 receiving arduino (firmata so it can receive info and send it to pd friendly numbers) 

2 xbee wireless interface for arduino (60)  (possible a Bluetooth version) 

9-volt battery holder 

Choose Sensors/Triggers:  

photo resistor ( 

flex sensor  (15) 

Light emitter 


Create "original" switch box to turn effects on and off: 

- See Picture of bobby's switch box as example. 

- Use switch type pictured for best "on/off" switching. 

List of  "effects" we would like to create (as a way of deriving sensors to get): 

        Approach: choose effects that will go well with intuitive response 

Pitch proximity - use light emitter in guitar so incidental movements will result in sound. 

      - Light emanating from guitar (switch mounted on guitar  lends itself to musical off and on motion) 

        Photocell sewn into knee- light emitting(independent circuit with a flashlight like switch) 

               Where do I want them? 

                Do I want a series of them? 

Effect  2: 

Pressure sensor 

Effect  3: 

contact mics in series around the suit 

to pick up fabric sound 

      - quadraphonic sound for the contact mics  

Effect 4 

Effect 5: 

List of  "compositions" we would like to create (as a way of deriving sensors to get): 

Contact mic Piece idea: 

One on each limb (then the room becomes an extension of your body)  

 The signal would go through a surround spatial zed audio system around the room).    

Video composition: 

- Small video cameras could be snapped onto the suit and someone could mix the live feeds 

Ask Questions to push the design envelope (I don't know what the fuck that means but it sounds good): 

- How important is the on off mechanism? 

  Should I have one on off capability? 

     Do you just use thresholds for on and off instead?
