# TeleMetrum
This is a recording dual-deploy altimeter for high power model rocketry
-with integrated telemetry link.
-
- 
- 
- 
-
-## 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!
+with integrated GPS and telemetry link.
+
+Production units are available from the
+[Garbee and Garbee](http://auric.gag.com) web
+store. TeleMetrum starter kits are also available from
+[Apogee Components](http://www.apogeerockets.com/Altus_Metrum_GPS.asp)

-## Problems ##
+## [Production History](../production) ##
-* 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.

The hardware design current gEDA files are available from

-the artwork as sent out for PCB fab. The 'loaded' tag on the master branch
-indicates the parts Bdale loads for a functional board, but the schematic
-does not reflect the cuts and jumps or added resistors. The 'nextcut' branch
-is work towards our next PCB revision. The 'ground' branch has a cut-down
-schematic used to generate the BOM for partially loading boards to use in
-the matching TeleTerra ground station design.
-
-Keith has working data collection firmware, however the firmware is under a
-massive, rapid rewrite to eliminate FreeRTOS which is much more generalized
-and capable than we need... and consuming more system resources than we
-can tolerate. As soon as we're over this transition, the sourcecode to the
-firmware and related tools will also be made available.
-
-As of 11 April 2009, the first two boards are fully checked out, we have some

+and logs telemetry to disk, displays current and max values for key parameters
+during flight, includes voice synthesis during the flight so that
+our eyes can stay on the rockets, and even includes live display of rocket
+position over moving maps! After flight, altosui can extract the
+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
