+A quick update as of 25 December 2008.  
+The circuit board artwork is out for fab!

+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
+as the basis for a completely new avionics design.
+The cc1111 integrates a full 70cm transceiver, 8051 processing core, and peripherals on one chip.
+We add to that a barometric sensor, temperature sensor, accelerometer, eeprom memory, and full LiPo
+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.
+We have a complete schematic and a first pass PCB layout that is currently
+under review and improvement prior to sending out for raw boards.
+</p>

+See the hw/telemetrum tree in our
+<a href="http://git.gag.com">public git repository</a> 
+for the current state of the gEDA design files.
+</p>

+We hope to be turning on boards and writing firmware over the 
+Christmas / New Years holiday season.
+Stay tuned!
