 # TelePyro
 
 This is an 8-channel pyro expansion board for [TeleMetrum](../TeleMetrum/).

 ## Motivation ##
 
 It would be nice to support more than the 2 channels of igniter control
 included in the stock [TeleMetrum](../TeleMetrum/) design, so that we can
 fly more complex projects involving staging, air starts, and backup ejection
-charges.  We also want to experiment with better circuits for testing igniter
-continuity, with the hope of being able to measure actual resistance and not
-just continuity.

 ## Future Plans ##
 
-We currently plan to build prototypes of TelePyro in Spring 2011.
+In late September 2011, v0.1 prototype boards were loaded and lightly
+tested.  They were never flown.  The prototypes of TelePyro were lost in the 
+[Black Forest Fire](http://www.gag.com/blackforestfire.html), and have not
+been replaced.
 
+If we ever get back to this project, the first thing we'll want to do is toss
+out the current design and start over, using an ARM Cortex SOC and our "new
+pyro circuit" that completely prevents processor brown-out.
