-# AltusMetrum
-
-This is the design that started it all!  Bdale got frustrated with existing
-commercial altimeters and decided to build his own.  This project was 
-presented in talks at LCA, SCALE, OLS, and Debconf in 2008.
-
-Here are photos of the front and back sides of the version 0.1 prototype PCB,
-which was 100% auto-routed on 2 layers using the 
-[gEDA](http://www.gpleda.org) 
-schematic and pcb tools.

-## Features ##
-
-### User View ###
-
-* Recording altimeter for model rocketry
-* Supports dual deployment (can fire 2 ejection charges)
-* Primary operations based on pressure sensor
-* 3-axis accelerometer
-* Temperature sensor
-* 2 serial ports for attachment of GPS and RF link modules
-* USB for data recovery and post-flight power source
-* Flexible battery choices
-* Designed to fit 24mm airframe tube
-
-### Developer View ###
-
-* NXP LPC-2148 Processor (ARM7TDMI-S)
-	* 512k Flash memory, 32k RAM
-	* USB plus lots of analog, digital, and serial I/O
-* Microchip 24FC1025 CMOS serial EEPROM
-	* 128k x 8
-	* I2C interface
-* Various Sensors
-	* Freescale MP3H6115A pressure sensor
-	* Freescale MMA7260QT 3-axis accelerometer
-	* Microchip MCP9700A temperature sensor
-	* (Honeywell 2-axis magnetic sensor left out of v0.1)
-* Software Features
-	* Written mostly in C with some ARM assembler
-	* Runs from on-chip flash, uses on-chip RAM, stores flight data to
-		serial EEPROM chip
-	* USB serial emulation for "console" interface
-	* Uses GCC, newlib, FreeRTOS, LPCUSB
-	* Based on a demo package written for the Olimex LPC-P2148 eval board
-		by J C Wren
-* Licenses
-	* The hardware is licensed under the [TAPR](http://www.tapr.org) [Open Hardware License](http://www.tapr.org/ohl.html)
-	* The software is licensed [GPL version 2](http://www.gnu.org/licenses/old-licenses/gpl-2.0.html)

-## Problems ##
-
-In addition to the various "oopses" that were found and fixed during initial
-turn-on of this board, several issues contributed to the decision to shelve
-the design for now:
-
-* lots of work went in to trying to make the board fit in a 24mm airframe,
-  but the resulting design with battery is really too heavy for such a small
-  rocket.
-
-* the 3-axis accelerometer has a max scale of +/- 6g.  This is insufficient
-  for characterizing the kinds of motors that we're playing with now.
-
-* while using a gcc-based toolchain to cross-develop for the ARM7 core works
-  reasonably well, it's a heavy toolchain to build and maintain, and the
-  processor really is serious overkill for the task at hand.
-
-## Artifacts ##
-
-The best version of Bdale's [Peace Love and Rockets](AltusMetrum.odp) 
-presentation about this hardware generation was given at the Ohio LinuxFest 
-2008.  Note that there are many photos included, so this is a HUGE file!
-
-The version 0.1 design had enough issues that Bdale decided not to publish
-it.  Work on an 0.2 revision is mostly complete at the schematic level, and
-some printed circuit board artwork updates were made, but a second run of
-boards was never attempted.  This design is now mostly of historical interest.
-
-## Futures ##
-
-If we decide to do further work on this design, a number of changes seem
-potentially appropriate for the next board revision, in addition to just
-fixing bugs found in the turn-on of the initial boards.
-
-* The LiPo battery support from [TeleMetrum](../TeleMetrum) should be copied
-  into this design, replacing the battery screw terminals with a standard LiPo
-  2-pin battery connector.
-
-* The [SparkFun](http://www.sparkfun.com) folks have produced 
-  a [USB bootloader for the LPC2148](http://www.sparkfun.com/commerce/tutorial_info.php?tutorials_id=94).  It 
-  requires an SD card for temporary storage of code to be
-  flashed.  Replacing the current external SPI memory chip with a microSD 
-  socket could make sense.  The socket size is under a cm square, and ones 
-  that have a fold-up locking top are about $2, vs over $6 for the current
-  memory chip.  The cards themselves are getting very cheap, too, and can
-  store much more data than the current 128k memory chip.  This would require 
-  moving ADC_Vbat to a different ADC input so that pins 27, 29, 30, and 31 
-  would be available for the microSD socket.
-
-* Consideration should be given to changing the accelerometer for a higher-G
-  single axis unit as in [TeleMetrum](../TeleMetrum) if we want to be able to
-  use it for motor characterization.
