Picking up on a thread I started a while back... Not sure if this will
lead to something permanent or not, but I tought I'd give it a try.
I got access to the back of my car's in-dash unit, and the video input
connector. It's meant for use with a back camera, which I currently
don't have (though it's on the wish list...). Found a VGA to RCA
adapter box, and fired up APRSIS32 which was loaded on a small laptop.
Here's the result:
Given the difficulty, if not questionable legality, of controlling a
GUI-based laptop while driving, I think the next steps need to include:
1. Replace the laptop and VGA adapter with a Raspberry Pi. VGA output
is built-in, also much better power draw and small size. (The car is a
sports car, so no room for anything bigger.)
2. Replace APRSIS32 with YAAC (for Raspberry Pi compatiblity).
3. Probably still need a keyboard for full control while parked, but
add some fixed key switches tied to keyboard shortcuts for the common
stuff while driving. During the earlier exchange, Andrew figured it was
a "simple" matter of a Java library to bridge the swtiches to keyboard
shortcuts... Hope he's right.
4. The Pi will boot itself when the car turns on, but I need a way to
automatically safely power down the Pi when I turn the car off. Any
ideas on this?
Anything else I'm missing?
