I'd like to build a remote device which reports its current 3-axis acceleration to a nearby (<10m) receiver. It needs to be as light and as small as possible. (I have no preference as to the receiving end, but ultimately the data will need to be pulled into a computer in real-time)
Does anyone have any recommendations as to how to go about planning this build? At the moment I'm looking at a low power digital accelerometer from Sparkfun and their simplest transmitter and receiver boards, I haven't really considered how I'd wire these together yet - I've selected these products for their size and low power consumption (~8mA together) so I can keep the inevitable battery really small too - the 5V requirement of the Tx board is a bit annoying (a coin cell would be perfect at 3V).
Any thoughts welcome, a winning answer would be one linking to material that helps me plan the circuit for the transmission of the data from the device back to the receiver.
EDIT:: On the advice of the commenter below I'll detail my thoughts on data rate needs.
I'd like to be able to be able to transmit the 3-axis acceleration of the remote unit in as close to real-time as possible, with a sample rate at 100ms or faster (though I'm prepared to be flexible on this)
To be a little clearer about what I'm building here, I'm trying to capture the acceleration data from things like juggling balls/poi etc to turn into visualisations on a computer. Thus size really is critical (XBee modules would be a little big I believe) however accuracy as to acceleration is not completely vital
