right now on the two respective PCB revisions. The 'ground' branch has a
cut-down schematic used to generate the BOM for partially loading v0.1 boards

For those who don't have ready access to the gEDA suite, here are pdf snapshots
of the files for Production PCB version 1.0 in more easily readable form.

-Our [AltOS](../AltOS) firmware works well enough that we now routinely fly
-TeleMetrum with no backup. Rockets with v0.1 boards have exceeded 50g
-acceleration, been above Mach 1, and reached altitudes greater
-than 12k feet AGL with great results. Keith's ground station program
-called ao-view logs telemetry to disk, displays current and max values for
-key parameters during flight, and even includes voice synthesis
-during the flight so that our eyes can stay on the rockets! We have post
-flight analysis software that makes it easy to extract data from the board,
-analyze it, and even generate KML files for viewing flights in GoogleEarth!
-More details on the software, including full source code and pre-built packages

+during flight, and even includes voice synthesis during the flight so that

+complete flight log from TeleMetrum, can display plots of the data from either
+the telemetry received by radio or the onboard flight log, can output a kml
+file for use with [Google Earth](http://earth.google.com), and can also
+output all the flight data as a csv file for easy import to spreadsheet
+programs or other analysis tools allowing you to perform whatever

## Future Plans ##
-As of May 2010, version v1.0 is available for sale from the
-[Garbee and Garbee](http://auric.gag.com) web store.
-
-Because we understand that not everyone uses Linux, development of a new
-cross-platform ground station program written in Java is underway for use with
-[AltOS](../AltOS).
+TeleMetrum v1.0 meets all of our expectations. We anticipate another
+production run of boards soon, which will include minor design tweeks mostly
+to work around component availability issues.
## Problems ##
### v0.2 ###
-* 100ma LDO regulator instead of the current 150ma part
-* no C38 footprint
-* different value for C36 reset capacitor

These are photos of our second version, which included the integrated Venus
GPS receiver, but with a passive patch antenna that turned out to have
disappointing performance due to our many PCB geometry constraints. It also
