## Future Plans ##
-We need to build and evaluate some prototypes, and review costing, before
-deciding whether this design will go into production.
+Initial hardware prototypes are assembled and working. Firmware is under
+development. We do not yet know what these will cost or when they might go
+into production.

+# 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
