<DIV>Damon,<BR><BR></DIV>That's fine. I have a DD1 PCB. I'll check Bo's PDF to
see if I have enough info in there. What I suggest we do then is that I create
the box as per the dimensions in the PDF and as soon as we have a real PCB, we
do a test print. As you saw last time, it is really easy to iterate if we need
to change something.<BR><BR></DIV>The one thing I may not be able to work out
from the PDF is the variation between versions (e.g. USB vs batteries) but I can
still start and we can validate the design once we have the first
PCB.<BR><BR></DIV>In this case, when would be a good deadline for you to have a
first version? Bearing in mind that I have lots of evening events this week, I
may struggle to have anything ready before the weekend: would that
work?<BR><BR></DIV>Bruno<BR><BR></DIV>

Bruno,<BR><BR>(Mark: could you help manage the detailed logistics of this box
+ PCB mechanicals/fab part?)<BR><BR>We can't put one of the real new REV1 PCBs
in your hands for at least 3 weeks. And there will be the Bo and PMS
variants which will probably be slightly different in various parameters
unless we are super-careful.<BR><BR>We do need to try to have the box as near
ready as possible by the time we do have the PCBs so that we can assemble
complete units without delay.<BR><BR>However, if Bo can confirm that the REV1
size, shape and mounting-hole locations are exactly as per DD1, then I think
you may already have one of those (or I can give you one).<BR><BR>We can
probably assume for now that component height on the SMD side is no worse than
the DD1 populated board too, and there is only the FDTI connector, AVR
(possibly socketed), LED and LDR (IIRC) above the board.<BR><BR>The micro USB
is below the board if used, I believe.<BR><BR>We'll need to deal with
buttons. We don't have to use the Maplin ones and could try to find
shallower devices to minimise case volume. (At a pinch for future revisions we
could consider side acting ones mounted on the PCB for example.)<BR><BR>Maybe
if we get you an accurate series of high-red PNGs you could work from them for
micro USB cutout placement, etc?<BR><BR>I'm happy to try to do a box design
session on whatever terms suit you.<BR><BR>Rgds<BR><SPAN class=HOEnZb><FONT
