the circuit is really minimal and simple. basically it's just the cc3000 wifi module, an atmega328, a 16Mhz chrystal, an on/off switch, one 1000mAh Li-ion and last two 6p connectors for the sensors.
the sensors are two modified minIMU-9.
with the battery fully charged i had it sending osc data at 50Hz for more than a whole day.
attached are schematics and arduino code for reading sensors via spi. the code also show how to talk to the cc3000 and send sensor data via osc.
there are also two classes for supercollider called
