    Hi fella's

    I am wondering if anyone would be able to help me. I'm looking to build a interface for my landrover defender to bring it into the 21st centry and also to be used as a valuable tool. It's going to be circuit building and programming and whilst I have some electronics experince and good at building PCB's via following instructions its something that I've never done before.

    I'm planing on using a raspberry pi 512mb as the brains of it. Everything then been fed from separate circuit board. I'm not looking for multimedia or Internet browsing in the car, I have my ipad for that which plays via a parrots hands free and also I have my ipad and tomtom for other needs. What I want is to use the pi to give me real time data of my car. I thought the best way is to layout what I want it to be able to display. Ill be using a 7 inch touch screen in the car.

    Basically oil temp, pressure, water temp, turbo boost & exhuast temp
    Doors open & closed
    Auxiliary lights on or off
    Center diff lock & rear diff lock
    Internal & external temperature as well as battery status
    My cameras, one forward facing, one reverse & one for tow hitch connecting.

    That's pretty much everything however where do you start and what sort of inputs do I need to create for a raspberry pi. I'm more than capable building the simply circuits that turn a switch electively on & off. I already can have those circuits light up a simple led its just the others I am not sure how to build or start,

    Regards

    Tom

    I think your biggest issue would be writing the software to translate the inputs into a useful display.
    There's also devices you can use to expand the IO ports on the PI.
