Now I just need a way to power the Palm III from an external source
(the batteries don't last when the Palm stays on, as when it's being
used for navigation)... I happen to supplement my paper aviation maps
with my Palm and "Fly!", a PalmOS aviation navigation program, but I
am limited to about 2 hours before having to swap batteries. I now
carry one of those portable car jumper batteries to charge the GPS
while I'm at my destination enjoying my $100 hamburger (so as to avoid
attaching this rig to the airplane's power system), but even with
that, the Palm itself doesn't last through a longer flight. At least
I have the nav app and a GPS compass app written into Flash... I lose
the maps when I lose power, but I can still use the Palm for location,
bearing, and ground speed without a sync, after swapping batteries.
Forget all that ... just follow the burger wrappers home. :)
I was wondering if you get ample sun to say have a solar panel on the
aircraft
to keep a spare set of batteries at charge. BG micro has a 12V 70 ma
solar panel
for about $27.
