For a DTV version check out the following website.  This version will 
be considerably larger than the DTV version.

The board Vince has designed is currently slightly longer than Jan 
Derogee's design, this is to accommodate through the hole components, 
rather than surface mount.  He has managed to keep it as small as it 
is by having the resistors "stand up" rather than "lay flat".  This 
is one of the questions I have for those interested in the boards. 
What is the preference.  I personally would prefer them to lay flat, 
even though it will result in a larger circuit board, as this will 
make it easier to solder.  It might also be worth while to allow more 
space between components.

For an idea of how tight everything currently is, here is a PDF of a 
version the board using a SD connector from Digikey.

Another question is about an enclosure for the board, should we 
decided on the enclosure first, and the board be designed to fit it, 
or just get the board done, and let everyone come up with their own
