    Post First ever Car PC attempt

    Hello mp3, I am so new to this I could be the old lady looking at a cell phone asking what is that back in 2000. I own a 1993 Nissan 240SX which I decided I want to look more up to date on the inside so after viewing some in car PCs on youtube I decided to give it a try but now I see it isnt that easy.
    I purchased an 8" Lilliput screen
    (Lilliput 8 Inch USB Touch Screen UM-80/C/T) and an ASUS mini computer to use
    (http://www.ebay.com/itm/ASUS-Eee-Box...-/181334363775)
    only to learn that I would not accomplish what I set out to do so that predicament brought me here.

    I would like to:
    View Auto diagnostics
    Watch movies
    Listen to music
    Surf the web
    and if possible GPS

    The most important thing of all is getting my diagnostics to show on the screen in real time, that is what I started out with the intentions of doing but saw the possibilities other people came up with. PLEASE if anyone could point me in the right direction I NEED SOME ASSISTANCE.

    the older guys will come up to tell you exactly what you want to know but giving you my point of view is that you can easy do all these things with a car pc similar to what you have in ur house but with mini itx mobos or you can take a linux based tablet and work with this.

    i personally took the first option . it needs some more work to be done due to sizes but at that time this is what i knew. if i would build a new one i would go through linux based board....! ( just for testing ), but i am a fan of the saying "the bigger the better" on the pcs . so mini itx is waht i vote for.

    what you are asking are simple enough. but as i told you before the older guys will light you up.

    welcome at the forum
    pavlos

    sorry i just saw the asus .....
    the right answer wold be probably "what do you want to know ?" anyhow my apologies.

    Probably what you need for starting is a frontend for controlling ur pc . it can do i think the most of the thigs you ve said.
    you also need some hardware like gps obd adapters .

    Thanks for the reply Happy_Feet
    So the ASUS is a right start to get what I need done? I'm just trying to get a feel for this and do it right the first time. i did plan to use a tablet at first but after seeing what you guys did in your cars I figure I would try the car pc route.

    I mainly need it to run/display my OBD1 stuff, show the codes when they come up, play my music and videos and get the GPS on it. I know I can download the hardware so that part isn't such an issue, I just want to be sure the Lilliput screen and ASUS will work for what I need it to before I installl it in the car, or should I try to sell it and get equipment based on the experts (mp3Car guys) recommendations.

    Sounds like a carPC to me? You have to decide if you want to go the Tablet route, D-Din all in one, or Separate Dash Screen and Trunk/Remote mount PC.

    My first attempt was the D-Din Android head unit route. Too limited for storage, USB glitches, too few car based apps for me, and sound quality was awful. Pulled that after suffering it just 9 months.

    Next up was a D-Din Win8 all in one PC. Problem was, every couple months I had to pull it out of the dash to add an SSD, wire in more USB ports to the MOBO header, and general tweeking in the box. Hassle, but fun and functional.

    The next car I did went with an aftermarket Metra bezel, modified to fit an 8" HDMI touchscreen, and all I put in the dash was the touchscreen, USB steering wheel interface, and the mp3car intellegent DC-DC converter to safely power the screen. I built the carPC into a Voom2 case, and in the past few months have already pulled it several times for updates, but it's behind the rear seat and only held by 2 screws, so it's quick and easy to take to the workbench for upgrades. In my opinion, this is the best way for a begginer carPC hobbiest like me to go.

    As far as Tablet's go, there are Android, Ipad, and Windows based tablets that have all been successfully used. I am working with another forum member in weekends helping install a Dell Venue 8 pro windows 8 tablet in now. It's a bit more dash work than the other routes because of the larger screen area needed for an 8" Capacitive screen with overswipe for win8 charms access, but it can be done.

    Now it's up to you to decide.

    forgot the most important . you need first of all a dc-dc power supply. if you go and check on the mp3 store you ll find a lot of options there. from that time you will be able to power ur pc in the house through an ac-dc power adapter or direcly in the car.

    my car pc is not screwed in the car . if i need to take this home it is a 1min job to get it out if the car. i got the idea from a sno's question about the mounting of the case.

    ur obd adapter must be a obd1 and there are several gps out there.

    but the most difficult and fun work is the hardware mods in the car that needs to be done for fitting screen and pc case.

    No, you don't need a DC-DC power supply.
    A DC-DC PSU is generally considered the best option for a number of reasons, but isn't absolutely necessary. An inverter would work, as well.


    ur obd adapter must be a obd1 and there are several gps out there.
    The OP's vehicle is 1993 and may or may nt have any OBD capabilities whatsoever.
    The US didn't mandate OBD on vehicles until the 1996 model year.
    Depending on the capabilities of the OP's 240SX, OBD may not be a possibility in stock form. There are alternatives to get engine data such as an aftermarket ECU or individual sensors to read parameters.
    Have you looked in the FAQ yet?
    How about the Wiki?

    And if you'd research just a bit further, you'd see that the PSU requires regulated 12v, which the vehciles electrical system doesn't provide.
    Running this EEE-PC straight from the car's electrical system will result in an unstable system at best, and damaged equipment at worst.

    Have you guys created a thread for your Dell Venue 8 Pro install? I'm curious how you are powering the tablet and working around the problem of using USB peripherals while charging? I am starting a build myself with this tablet and trying to figure out the best way to go about this. Thanks!
