-This is a very small, baro-only recording dual-deploy altimeter for
-model rocketry with integrated telemetry link.
+TeleMini version 2.0 is a small, baro-only recording dual-deploy
+altimeter for model rocketry with integrated telemetry link. It's
+currently in development, with production planned to start in the fall
+of 2013.
-## Motivation ##
+For the latest TeleMini firmware and related ground station software, please
+visit the [AltOS](../AltOS) page on this site.
-We'd like to fly smaller rockets really high, which motivates an interest
-in both electronic deployment and radio direction finding for post-flight
-rocket recovery.
+These are photos of our current prototype version:

## Artifacts ##
-The design files can be found on [git.gag.com](http://git.gag.com) in the
-project [hw/telemini](http://git.gag.com/?p=hw/telemini;a=summary).

-## Future Plans ##
+There is a single manual for TeleMini and all other Altus Metrum products,
+which is available in [html](../AltOS/doc/altusmetrum.html) and
+[pdf](../AltOS/doc/altusmetrum.pdf) formats.
-Initial hardware prototypes are assembled and working. We've flown a number
-flights now, with great results. Work remains to stabilize the firmware and
-associated ground software updates, particularly because we've made a major
-update to the telemetry protocol to more easily handle multiple products.
+An outline of the board with drill hole locations is available in
+[pdf](../Documents/easymini-outline.pdf] format.
-The first production hardware build is underway, and we expect to have
-TeleMini for sale sometime in August 2011, with plenty on hand to sell at
-[LDRS 30](http://ldrs30.org/) in early September!
+The hardware design files can be found on [git.gag.com](http://git.gag.com)
+in the project [hw/telemini](http://git.gag.com/?p=hw/telemini;a=summary).
