oMotive is my attempt at an OSHW version of the FitBit—a small, ingenious device for recording and analyzing body motion. The FitBit seems to be really great at what it does, and I’m not trying to steal market share, but I wanted to see if I could replicate the functionality in a completely open way. My current design uses an ATTiny2313 controller, ADXL345 3-axis accelerometer, RTC module, microSD-based OpenLog module, Bluetooth serial module, and lithium polymer battery. The approach is simple, but I’m not sure I can get the ATTiny2313 to properly interact with all those parts. We’ll see.
