[aprssig] LCD in the car

[Michael Hatzakis Jr MD]

Hi guys,

I've been doing this for a few years and works fairly well.  I've got an
inexpensive Innovatek 7" tough screen mounted to my dash with a tiny Dell
Inspiron in my trunk with a 12v power adapter.  

I have the desk adapter drilled the back of my back seat, so when the seat
folds down, I can access it flat.  I opened the laptop case and soldered a
wire to the on-off switch and put a small switch on my dash to turn on-off
and to reset.  I've got a small RF mouse and a keyboard in the glove box
when I need it.  Otherwise the touch works ok, not great.  

The PC has engine diagnostics loaded onto it with a connection to the
engine, a mapping program with GPS and a terminal program for my TNC and for
RTTY, among other things.  I've also got Winlink loaded with a remote to my
IC-706.  It's quite a lot of fun, but a little heavy on the maintenance.
Some little thing breaks down but usually easy to fix.  

With regard to the power issue, with a laptop, when power goes off, the
battery kicks in.  Although, I did wire a power-on delay circuit to reduce
the garbage with ignition.  Basically, it is a 555 timer with a relay and
waits 8 seconds to switch to auto 12v so as to allow me time to start the
car.  

I'll try to take some photos and send it to the list.

Hi,
Will someone explain how they are turning on and off
their computers if they are remotely mounted
physically away from the display screen like under a
seat or in the trunk?  The way I understand computers
is that they have a physical on/off switch.  If they
lose power such as through an ignition sensed relay
they shut off until you push the switch to turn them
back on.

Thanks,
Chris
