[Arm-netbook] tablet re-re-design

[Luke Kenneth Casson Leighton]

ok so i tried the new layout... _after_ joining all the tracks up of
course... and unnnfortunately the cpu card slot is so far down that
the battery is squashed badly at the bottom (long) end and is far too
small.

so... aaaaaaagh! i have to begin again :) next attempt will be to
turn the cpu card round 180 degrees (so it comes out on the right).

ah all good fun...

poor luke, my sympathies. thanks again for your hard work :)

appreciated. tough silly lessons all round.. now i know that for
things like this, esp. where space is a premium, you absolutely must
design the casework in conjunction with the PCB. so i'll be including
generation of images and overlaying them onto blender as part of the
iterative process.

the current plan is a full-length PCB with power jack on left, CPU
card rotated *downwards* but with the rails over-reaching the edge of
a much shallower PCB. headphones, USB and power button are currently
all on the right.

the battery can then be a maximum of 6.0mm high, sitting to the right
of the CPU card. it can be surprisingly big, taking up almost 50% of
the space.

the LVDS converter PCB that sits on top of the LCD runs the full
length of the LCD, and the rev 3.2 PCB sits flat directly on top of
the LCD, clear of the LCD's PCB. LCD is 160x105, the LCD PCB is
160x35mm, and the rev 3.2 PCB is about... 175 x 70. i'm going to try
to make that 175 x 63.

lots to sort out: i might have accidentally moved the touchpanel
connector and camera connector, the positions of which are absolutely
critical. have to work those out tomorrow.

so much to do!

l.
