The circuit boards inside of wii remotes are much smaller and lighter,
then you can use whatever battery gives you about ~3V.

Hey all,
I love this list:)
I had thought about wiimotes but I think they are too cumbersome,
visible and heavy. I would like the instrumentalist to not have to
be aware that they are connected to anything. The point of the
tracking is to use the performers involuntary movement as input data
for the pd patch, so I would like for them to be as un-selfconscious
as possible.
I have heard that there are problems with bluetooth in concert
situations, although the feedback I have just received from you guys
seems inconclusive?
Although this is in a university setting for the 1st performance,
I'm also really keen that this can be portable and as inexpensive as
I can make it, thus hopefully allowing the piece to have a life
outside of academia. This would prohibit going down any super-
complex routes.
I think I would be more comfortable not having to rely on the sensor
being in the line of sight too, sounds scary.
Brilliant feedback so far though, thanks a lot, I have plenty to get
on with. I will, no doubt, be reporting back soon...
Cheers,
Jb

Tracking in that sense requires you to have gear that is in visible
line of sight to the musician. If its a concert situation maybe
that's not easy. But its a way to go. Note that will not produce
good tridimensional tracking results, one could use a kinect too.
If we want to hyper extrapolate, if the concert is in a controlled
room, you can use 3D IR tracking system, such as used for mocap.
Real expensive but really accurate. :)
Best luck,

Maybe it's worth mentioning that you can also work the other way
round:
mount a small IR LED on the head of the instrument and track its
motion with a wiimote mounted statically in front of it.
I used this once for tracking a remote controlled robot and it
worked fairly well.
I guess that success will also depend on the type of movements the
musician will make.
The IR LED would need to stay directed to the wiimote all the times.
Also make the LED as omnidirectional as possible...

Hi, i connected pd with arduino and adxl330, works fine, in order to
wireless i prefer arduino bluetooth, the only thing to do is change
the baud for default the in firmata is 57600, in my experience only
works if you change to 115200 (in the standard firmata arduino
sketch,and the arduino monitor).
If you have problems i can help you, i send a youtube video , pd
+arduino+processing+osc wired...but arduino bluetooth or bluetooth
shield for Arduino is the solution.

Hey all,
I'm working on composing a piece within pd for viola in which I
would like to attach some kind of sensor to the head of the
instrument. The sensor must be capable of tracking the performers
movements on the x,y,z axis', be undetectable for the performer, and
be wireless. I'm not sure whether something arduino or some sort of
bluetooth device would be preferable?
Would be very grateful if any listers have any experience in these
matters and could recommend some devices, pointers of things to
watch out for (bluetooth in concert venues for example), general
sturdiness of various items, etc.
Many thanks, and best wishes,
Julian
