Homebrew PCBs

Yeah I used an HD44780 display in an MP3 player project for my van 
recently just because
of how simple it was to interface with.  The only reason I suggested 
maybe a serial LCD for
this project is because the microprocessor appears to have a serial port 
open and probably
wouldn't require a massive change to the schematic since the real 
changes would be in the
code.

  I guess it comes down to whether one is more comfortable reworking the 
circuit or
the programming.  But if serial LCDs are that much of a pain starting 
from scratch using
this project for inspiration might be the better way to incorperate an 
LCD.  Either way
I'd love to see someone do something like this with an LCD readout.
