## Artifacts ##
The hardware design current gEDA files are available from
-[git.gag.com](http://git.gag.com). The 'fab' tag on the master branch reflects
-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.

+[hw/telemetrum](http://git.gag.com/?p=hw/telemetrum;a=summary).
+The 'working-v0.1' tag on the master branch indicates what we're actually
+flying right now. The v0.1 PCB artwork, and schematic updated to include
+the parts Bdale loads for a functional board including the two cuts and jumps
+and two added resistors plus ground leads required as rework. 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](../TeleTerra) ground station design.
+
+For those who don't have ready access to the gEDA suite, here are pdf snapshots
+of files in more easily readable form. These are all as of the working-v0.1
+tag:
+
+* [schematic](telemetrum.pdf)
+* [pcb artwork](telemetrum.pcb.pdf)
+* [bill of materials](telemetrum.bom)
+
+
+We have firmware that is working well enough that we're starting to allow
+TeleMetrum to fire ejection charges. Keith has also written a ground station
+program called aoview that logs telemetry to disk, displays current and max
+values for key parameters during flight, and even includes voice synthesis
+during the flight so that our eyes can stay on the rockets! The source to all
+this is available from [git.gag.com](http://git.gag.com) in the project
+[fw/altos](http://git.gag.com/?p=fw/altos;a=summary). This repository includes
+sources for the firmware, ground station program, and related utilities. Note
+that actually building these sources requires a modifified version of sdcc,
+for which we have not published diffs since they are in the process of being
+accepted upstream. Watch this space for more details.
+
+## 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 beeper
+* eliminate temperature sensor, since baro sensor is already compensated and there's a sensor on the cc1111
+* eliminate serial port connector
+* integrate MN5010HS GPS receiver and chip antenna on-board
+* change debug connector to 4 pin 1.25mm connector as was used for serial port
+* add 7 pin 1.25mm connector for companion board interface
+* use v_lipo as pyro power, eliminating the huge 1000uF capacitor and instead
+ adding ballast capacitors on the 3.3V rail to prevent brownouts
+* add a rectangle of silk screen material for improved serial number labeling
+
+We hope to build and fly prototypes of this version in late 2009. If it works
+out as well as we hope, this version may be made available in assembled and
+tested form to others in the rocketry hobby who have expressed interest.
