Default Drive Small VGA screen from PDA


12 volt VGA flat screens technology exists to allow people to view
DVDs in automobiles.

Has anybody installed a small 12v VGA monitor in a glider to display
the PDA Navigation info in a larger format ...

Here is a link for a VGA cable for the dell x50v. You can also buy
just the cable and create your own interfaces to the VGA, GPS, and
power.

Interesting idea which I had thought about for automotive use. Of
course there is increased power draw but it would be a poor man's
ClearNav. Does only the Dell's provide you VGA out? How about
IPAQs. Thanks.

A number of PDAs have VGA displays. I just happened to see the VGA
cable advertisement and realized the Dell did not need any other
components to drive a VGA display. I would think the other PDS could
also do this, although I am not sure. I have found a document for the
DELL pin outs, which would allow you to construct a cable with
interfaces to the VGA, GPS and a power source. Yes, sticking together
a bunch of off-the-shelf components does look like a poor-man
solution, but more like the Craggy Aero design approach. I understand
the ClearNav design focused on ergonomics and NK designed all new
hardware and software components to achieve this goal The price of
both systems is very close, however, and much higher then this poor-
man approach would cost - if it worked. It's hard to believe someone
has not experimented with this already.

Here is the Dell pin out map. Look at the bottom of the page.

I'm waiting for someone to build one of these based on an OLED
display. They appear to be much brighter and far lower in power
consumption than LCDs, plus incredibly thin. The expectation is they
will be cheaper to produce than LCDs in volume - eventually.

Actuall the Craggy Aero Design focused on performance and value to the
customer. It has 1" larger on the diagonal screen, 3 to 4 times the
processor speed, 4 times more resolution 640X480 , State of the art
Software SeeYou Mobile or WinPilot and a very erogonomic hand held
ball track mouse. No messy boards on the back and $300 less than a
Clear Nav.

hmmm ... ok, so looking at the mix of off the shelf components, how
come it is only 300 less ... shouldn't it be half the cost of a
ClearNav? Or is the difference reflective of a higher mark-up?

It sounds like you are confusing production cost (labor and component
cost) with selling price, which is usually set by market considerations,
not per unit cost. I doubt anyone selects their next soaring instrument
based size of the markup!

The price it "should" be is up to the seller. Why not ask NK if their
price "shouldn't" be twice the cost of the Ultimate?

Personally, I'm hoping Richard has a huge markup on the Ultimate,
because that will encourage others to enter the market with better or
cheaper units.

From what I understand, they both use basically 'off shelf'
components... ClearNav's are in custom molded plastic shells and
Craggy Ultimate's are in custom anodized aluminum shells... ClearNav
runs a hopped up version Glidenav II (GlideNav III?) where Craggy runs
SeeYou Mobile or WinPilot, neither of which are exactly slouchy.
ClearNav is soon to have a vario to go with it and is also expecting
it's logger to receive IGC approval though, which will greatly improve
it's cost effectiveness however. Not sure about Richard's plans in
this dept, but I think SeeYou is working out a Craggy specific version
for it... Richard?
