This works great!!! -- but is there a way to stop the blue LED (STAT1, to the right of the 'g' in "openLog" written on the board)?
It keeps flashing, perhaps to indicate serial communication between my arduino board and the openLog.
I want to do day-long logging of biometric signals (initially at a high data rate, to figure out what is going on, then hopefully at a lower rate) - and I wonder how much of the battery gets used up by the blue LED flashing non-stop.
Right now I am just using an Arduino mini, an openLog, and a 3-axis accelerometer, and logging x,y,z at 4Hz draws 10mA from the battery!
No public wish lists :(
