+Notes about things learned or observed during debugging:
+
+* The RC networks for the input pins are closer to the stacked 15-pin 
+  connectors than I'm really comfortable with.  Nothing is making contact or
+  shorting, but I'd be tempted to increase the spacing on a future board cut.
+* The SMT 330uF cap is kind of a pain, and doesn't seem all that mechanically
+  solid after reflow.  Switch this for a through-hole part in the future?

 ## Future Plans ##
 
 As of late December 2011, the first prototype v0.1 board has been loaded and
 is being debugged and tested.  If the board "works for me", then I'm likely 
 to make enough of these to sell to others who are interested.

+Unfortunately, in June of 2013, our house fell victim to the 
+[Black Forest Fire](http://www.gag.com/blackforestfire.html).  The
+prototypes of this board were lost, along with everything else.  I do not
+know if or when I might ever get back to this...
