Great ideas. |

First generation, I thinking Arm9, maybe a pandaboards with some LED |
| 31 |
screen mounted together with 2" nylon standoffs. That way, when |
| 32 |
I figure out how to add a board that receives and processes signals |
| 33 |
from the depth finder, I can use 12 or 14 bit AD to input into |
| 34 |
the panda board. |
| 35 |
|
| 36 |
I may also rig a temperature sensor to the boat hull, or via a tether. |
| 37 |

What concerns me about openstreetmap, is I had envisioned a system where |
| 39 |
the database is downloaded to the operator's embedded system depending |
| 40 |
on the anticipated area of local/regional travel, thus not having to |
| 41 |
depend on constant/reliable internet access. |
| 42 |
|
| 43 |
Sort of a GPS/nautical navigation system, under the control of the |
| 44 |
operator. I'm still learning about openstreetmap so I have moved those |
| 45 |
issues (as suggested by our Mike) to that forum, for now. |
| 46 |
|
| 47 |
From my initial research so far, nothing exist for a marine |
| 48 |
environment, so I'll most like roll-it, including some epoxy |
| 49 |
coatings and daughter board on the first-gen effort. |
| 50 |
|
| 51 |
My reason for using this list, is to flush out any gentoo-ish |
| 52 |
common ground or any hardware suggestions; not an expose |
| 53 |
on openstreetmap.... |

It's liable to be a few months to cmplete this research, but, |
| 59 |
I'll post back, or drop you some private email, if you are the |
| 60 |
only one interested in what I learn. |
