+A quick update as of 16 December 2008.
+The ARM7-based 'AltusMetrum' design has been shelved indefinitely.
Working with Keith Packard, I recently embarked on a complete redesign based on the TI cc1111.
We got there by deciding we need a low-power RF beacon for post-landing direction finding, learning
of the existence of this part, then realizing that we could radically simplify things by using it
battery support powered by a USB interface also used for configuration and post-flight data extraction.
It looks like we can get all the features we want on a single board for less than the price of most
commercial altimeter boards, with the only downside being dramatically reduced processing power.
-The schematic is under design review now, PCB layout will begin soon, and we hope
-to be turning on boards and writing firmware over the Christmas / New Years holiday season.

Thanks for looking, but there's not much here yet...
