I've been interested in plugging a computer into my car (98 Honda Prelude) for over a year. I think I'll finally have the time and money to do it this spring/summer.
What I am looking on having:
Mini ITX Board
Notebook Hard Drive
12V DC to DC Power Supply
COM Port for GPS
Flip up In Dash LCD Screen
ITPS-Auto Power Sequencer
USB mini hub to the glove box for keyboard/mouse and WiFi
Well thats the general idea, the problem I'm having is choosing the board and LCD screen, and MP3 input method. I know the Mini-itx has VGA out, but wouldn't this produce less than optimal (ie fuzzy) pictures on an LCD screen? I'm not too concerned with cpu processing power, as long as it has enough to play DivX movies.
Would a M-100 be adequate for car use? Could I squeeze a notebook drive into the case? Other issues to be worked out are controls for mp3 playing while driving. I've considered using an IR remote, but I would need a second COM port for that. Also I would like to know how complicated it is to patch the audio output into the regular car stereo.
I prefer not to do any significant modification to the visible interior of the car as in I'd prefer it to appear stock. I'm not sure how much free space I have, as I haven't looked yet. I have at my disposal (at work) an array of tech tools, soldering irons, oscilloscopes, but I'm not an EE.
I live in Northern NJ, so I don't think the temperature swings will be two wild, but I may visit Texas at some point in the future. I'd hopefully be able to play MP3s/GPS navigate while on the trip.
My overall budget will hopefully be under $1000.
Currently I'm still in the design/research stages and choosing the components. I hopefully will be able to put it together this spring or summer.
