# TeleShield
This is an RF interface board for use with [Arduino](http://arduino.cc)
The RF filter components are set for use in the vicinity of 435 Mhz.
+These are photos of the first prototype:

## Future Plans ##
-Prototype v0.1 boards will hopefully be working in time to show at the
-Arduino mini-conference at LCA 2012 in mid-January.
+The prototype v0.1 boards work fine. Feedback from showing them at the
+Arduino mini-conference at LCA 2012 resulted in elimination of the Bluetooth
+interface. Updated boards have not been built yet, but
+[schematic and artwork files](v0.2/) are available for review and comment.
+
+No significant interest in this design ever materialized, so we have no plans
+to make any more at this time.
