So I'm working on a project that requires a 3-axis accel, 3-axis gyro wireless setup.
I'm prototyping using Wii Motion+, but want to settle in on XBee-based hardware in the end.
What would be an easier road to go down?
Using an ArduIMU+ ($99)http://www.sparkfun.com/products/9956
And attaching an XBee to it (connecting TX/RX/3.3v/Gnd). ($23)http://www.sparkfun.com/products/8664
Using a MiniBee ($49)http://www.sensestage.eu/?page=details&prod=8&cat=2&page_id=40
And attaching a 3-axis gyro to it: ($49)http://www.sparkfun.com/products/9801
(I know the second setup still needs an XBee ($23) attached to it, but it has the appropriate headers in place so it's just a drop in)
I didn't realize how expensive 3-axis gyro boards were on their own($49?!), otherwise the MiniBee would be a no-brainer.
I did look into maybe hacking a wii motion+ dongle as the 3-axis gyro (as these are quite cheap($15-20)) but it uses i2c, which means I would have to reprogram the MiniBee in order to read the wm+ (?).
Here's the link I found on that:http://makeprojects.com/Project/Hacking-the-Wii-MotionPlus-to-Talk-to-the-Arduino/593/1
Since I live in the UK the MiniBee boards are pretty cheap, it's the 3-axis gyro boards that would be expensive. The ArduIMU+ is the most expensive, but has everything built in (barring the XBee).
Both are fairly elegant hardware solutions (arduino+xbee for MiniBee and arduino+sensors for ArduIMU) but both will require some added hardware/dangly bits.
Both of them would have an XBee + USB Explorer on the receiving end (http://www.sparkfun.com/products/8687
