Some doubts: Lilypad Arduino, Accelerometers and E-textiles Answered
First of all, I'm a brazilian undergraduate Design student, and I'm very new at developing electronic projects (specially with e-textiles). I'm currently working on a malleable hand-held interface for my graduation project, and have been posting its development at this website: http://theinstrumentproject.tumblr.com/
Well, I've come up with the attached simplified schematics (just to communicate my needs and current intentions), and some questions raised from it:
About Arduino and the schematic:
- Will the raw data of the whole schematic (5 accelerometers to lilypad to bluetooth) be fast enough generated? - a frequency of 10 "readings" per second should be enough for what I intend to do with them. *
- How much power will the schematic consume? Are three 20mm coin cell batteries going to do the job? In how much time would they be drown out? *
About soft circuits and e-textiles:
- What is best to transport data and power through this interface: conductive fabric, conductive thread or even a really thin wire? - It is important that it could be folded, twisted and very resistant through time.
- Could you indicate any kind of textile more suitable for this application? - It should be just a little stretchy, and very resistant.
- Any ideas of how should I protect the components from damage by rough hand manipulation?
- Any advice about sewing the whole application?

Hope someone here can bring me some light to these problems, but any kind of help, opinion or critic is welcome!
