-Keith has working data collection firmware, however the firmware is under a 
-massive, rapid rewrite to eliminate FreeRTOS which is much more generalized 
-and capable than we need... and consuming more system resources than we 
-can tolerate.  As soon as we're over this transition, the sourcecode to the
-firmware and related tools will also be made available.
 
-As of 11 April 2009, the first two boards are fully checked out, we have some
-initial firmware capable of data logging ready, and as soon as we get a good
-day to fly we hope to log our first flight data!
