it was    enormously enormously time-consuming.)  So, it's not pretty but it works, as the saying goes....  &gt;:-)  Anyone    want to see?  Here's the board:          http://axio.ms/photos/BeagleBoardLVDS/LVDSBoard.jpg  Here's the space once occupied by the TFP410, with 33 gauge wirewrap    wires being soldered on (apologies for the crappy picture quality).    The flux is making it look a little messy, but it cleaned up.          http://axio.ms/photos/BeagleBoardLVDS/Loupe.jpg  The umbilical wires in place:          http://axio.ms/photos/BeagleBoardLVDS/Wires.jpg  Finally, the two welded together:          http://axio.ms/photos/BeagleBoardLVDS/AttachedToBB.jpg  Naturally I forgot to take a final shot before it got whisked away    abroad (d'oh! :) ), but it worked splendidly.  I believe the prototype    photos of a certain OMAP3-based device announced this week are it in    action.....  Am looking forward to (I think Keith Williams's) revC daughterboard.    One thing to note is that most LCDs will require a lot of current on    the 3.3V rail and will require an extra 3.3V power supply/regulator    from the BB's 5V supply;
