One day very soon, you will have to teach me how you are using the
planes. I never dug up a tutorial on that, so to me, it looks like a
lot of stuff is still unconnected ;)

Anyway great work.

I think our meeting discussion really helped to make is think about
keeping it simple, which as Rick Sheridan pointed out, might make this
more practical than Sharp's solution.
Also, a LOT cheaper, which ultimately transcribes to MORE units made
and in use!!!!

What do we think of adding a fuse? On board would be difficult to
change in the field, so I am more inclined to suggest an inline power
cable fuse outside the case, so that it is easy to change if
necessary. Another option would be a panel mount fuse on the case
itself. I really, REALLY think we need to put a 4 amp limit on there
somehow. The 3.3 volt 1 amp regulator will take care of itself, but I
am not certain about the DC-DC converter.

I know we said no to power switches as well. However, I strongly feel
like we do need one. It does not need to be part of the PCB though.
Remember that we will have high output solar cells and hefty batteries
connected to this thing. It might be nice to have an off switch.

Anyway, I think as is, the PCB is good. I personally feel like the
power switch and fuse ought to be off-board.
Also, lets see what happens when I meet with GSE monday (remember
thats Tuesday for your. Hopefully I can have news for you by Tuesday's
meeting.)
