+# TeleScience
+
+This is an expansion board for [TeleMetrum](../TeleMetrum/) intended to 
+support science projects.  It provides 12 analog inputs with selectable
+thermistor support, and 5 general purpose I/O pins.  This board can also
+be used standalone as a USB I/O device.
+
+## Motivation ##
+
+Bdale's son Robert is interested in mapping the temperatures experienced
+by nose cones and fins in flights beyond Mach 1, and we're working with 
+our good friend Jeff Lane from 
+[Shockwave Rocketry](http://www.shockwaverocketry.com/) 
+to instrument one or more of his nose cones in pursuit of that goal.  And
+it's easy for us to imagine other experiments that would be facilitated by 
+having generic analog data inputs and a few control lines.
+
+## Features ##
+
+### User View ###
+
+* Small circuit board mounted near [TeleMetrum](../TeleMetrum/)
+* Requires [TeleMetrum](../TeleMetrum/) v0.2 or later, as v0.1 does not 
+  have the required companion board interface
+* 12 analog input channels, each of which can independently be configured
+  for an NTC thermistor or generic 0-3.3 volt analog input.
+* 5 general purpose I/O lines
+* On-board flash memory for data logging.
+* USB interface for programming and development
+

+## Artifacts ##
+
+A schematic exists on [git.gag.com](http://git.gag.com) in the project 
+[hw/telescience](http://git.gag.com/?p=hw/telescience;a=summary), 
+but no prototypes have been built yet.
+
+## Future Plans ##
+
+We currently plan to build prototypes of TeleScience in Spring 2011.
