-## 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.

-## Problems ##
-
-* The CC1111F32 is a 36-pin QFN package, which necessitates reflow 
-  soldering.  Since we needed to reflow solder anyway, and because TI used 
-  them in their reference design, we went a little crazy and used 0402 
-  passive parts everywhere.  That means working under a microscope to 
-  place parts!  Without an inspection microscope, loading and testing these
-  boards might be impossible.
-
-* The v0.1 artwork had three issues, two of which required physical rework
-  on each board.  All of these issues were fixed in v0.2.
-
-       * The USB connector footprint was placed wrong, so that the
-         connector hung out over the edge of the board instead of being 
-         flush.
-       * We needed chip select on the SPI memory.  To fix that, we gave up the 
-         ability to put the accelerometer into self-test mode and used that 
-         GPIO line to pull chip select on the memory, which required two
-         cuts and two jumpers.  
-       * The igniter sense circuits each needed a second resistor to 
-         complete the voltage divider so our 3.3V CPU ADC could read the 
-         5V ejection voltage.  This was fixed by changing two resistor 
-         values, and tacking two additional resistors onto the board
-         with jumpers to ground.

-As of early February 2010, three prototypes of v0.2 are done and working on 
-the bench.  We hope to flight test them shortly, then arrange a production
-run in time to make TeleMetrum available in assembled and tested form to 
-others in the rocketry hobby who have expressed interest in time for the 
-2010 flying season.
+TeleMetrum v1.2 is now available for sale.  Eventually we'll run out of v1.2
+boards, and by then no dobut we'll have found more things to tweak...
