-## 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 has the USB connector footprint placed wrong, so that the
-  connector hangs out over the edge of the board instead of being flush with
-  the edge.
-
-* The v0.1 artwork has two issues that require cuts and jumps.  The first is
-  that we need chip select on the SPI memory.  To fix that, we give up the 
-  ability to put the accelerometer into self-test mode and use that GPIO line
-  to pull chip select on the memory.  The second is that the igniter sense
-  circuits each need a second resistor to complete the voltage divider so our
-  3.3V CPU ADC can read the 5V ejection voltage.  This is fixed by changing
-  two resistor values, and tacking two additional resistors onto the board
-  with jumpers to ground.

 ## Future Plans ##
 
 
 ## Future Plans ##
 

-Work is underway on a second revision of TeleMetrum with the following changes:
-
-* stretch board length by 0.25 inches
-* adjust USB connector position to be flush with edge of board
-* eliminate temperature sensor, since baro sensor is already compensated and there's a sensor on the cc1111
-* eliminate serial port connector
-* integrate SkyTraq Venus GPS receiver and patch antenna on-board
-* change debug connector to 4 pin Tyco MicroMaTch
-* add 8 pin Tyco MicroMaTch connector for companion board interface
-* use v_lipo as pyro power, eliminating the huge 1000uF capacitor and instead
-  adding ballast capacitance on the 3.3V rail to prevent brownouts
-* move all connectors, beeper, and GPS patch antenna to the "other side" of the board from the surface mount parts
-* add a rectangle of silk screen material for improved serial number labeling
-
-As of early December 2009, the layout work for v0.2 is done and we're busy
-verifying it and deciding exactly how we're going to build them.  We hope to
-have first prototypes to test in time to show the new version at LCA in late
-January 2010.  If it works out as well as we hope, v0.2 may be made available 
-in assembled and tested form to others in the rocketry hobby who have 
-expressed interest sometime in 2010.
+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...
