So, I'm looking at options to build/hack a
GPS device, combined with some sort of
embedded gentoo friendly Tablet.
I'm thinking of multiple channels
of audio output so it is a 5.1 mp3 player too,
for a boat or a RV or an car. Mobile so it can
be moved between vehicles with a quick connect
to sensors and speakers.
Nokia N900 or new N9 (I have an N9, but the N900 probably has more
hackers around it and cheaper second hand items)
Build something around a gumstix - not that cheap, but I think they have
all the bits ready to plug together. Probably low enough power you could
battery power it
Very easy to hack is a PC Engines Alix + laptop screen. (In some ways
that's called a 1 laptop per child I guess.... Add that to the list)
Great ideas.
Good luck finding a Gentoo friendly tablet? I would be interested if you
find something?
First generation, I thinking Arm9, maybe a pandaboards with some LED
screen mounted together with 2" nylon standoffs. That way, when
I figure out how to add a board that receives and processes signals
from the depth finder, I can use 12 or 14 bit AD to input into
the panda board.
I may also rig a temperature sensor to the boat hull, or via a tether.
What concerns me about openstreetmap, is I had envisioned a system where
the database is downloaded to the operator's embedded system depending
on the anticipated area of local/regional travel, thus not having to
depend on constant/reliable internet access.
Sort of a GPS/nautical navigation system, under the control of the
operator. I'm still learning about openstreetmap so I have moved those
issues (as suggested by our Mike) to that forum, for now.
From my initial research so far, nothing exist for a marine
environment, so I'll most like roll-it, including some epoxy
coatings and daughter board on the first-gen effort.
My reason for using this list, is to flush out any gentoo-ish
common ground or any hardware suggestions; not an expose
on openstreetmap....
Good luck

It's liable to be a few months to cmplete this research, but,
I'll post back, or drop you some private email, if you are the
only one interested in what I learn.
