-Production units are available from the
-[Garbee and Garbee](http://auric.gag.com) web store.
-
-These are photos of our current production version, which includes an
-integrated GPS receiver with active patch antenna:

-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
-used a voltage regulator with less capacity which we felt was marginal for
-supporting the companion boards we have planned:

-And this is a photo of our original board with serial port for off-board GPS,
-without the big off-board 1000uF cap from the original ejection circuit:

-## Motivation ##
-
-Bdale and Keith both own
-[BeeLine](http://www.bigredbee.com/BeeLine.htm)
-trackers from
-[Big Red Bee](http://www.bigredbee.com), and are pretty happy with them.
-They use a PIC processor and a TI CC1050 transmitter chip, and
-operate in the ham radio 70cm band.
-
-One weekend while attending a conference together, we got to wondering if
-we couldn't adapt one to use as a downlink for the
-[AltusMetrum](../AltusMetrum/) altimeter board in addition to direction
-finding after flight. That caused us to start thinking about other things
-in the design we might want to tweak, and before long we were working on the
-design of a new tracker board derived from the BeeLine design.
-Another friend at the same conference showed us a board he was working on
-using a different part in the same TI series, that integrated a transceiver
-and CPU on the same chip.
-It didn't take us long to realize that with such a part we could combine and
-simplify things by building a new altimeter with integrated RF link! And
-after gaining some experience in 2009 with a first version, we realized we
-always want GPS on board, which lead to our current second generation boards.

+Prototypes of v2.0 were flown at Airfest 2013 and everything worked
+great. TeleMetrum v2.0 is now available for sale.
