    Smile 96 Toyota Corrola Sedan Budget Laptop In Car PC

    First of all thanks all fellows in Mp3Car... without your helps I couldnt make it

    Here is my 96 Toyota Corolla Budget In Car PC using Sony Viao Laptop.

    UPDATE 10 Oct 2010 *******************
    Just found got some free time to upgrade previous my carpc setup and add new functionalities:
    • Infrared remote control
    • Update navigator to Garmin PC
    • Enhanced video and audio playback
    • Added Super Nintendo emulator and embedded to Ride Runner (Zsnes)
    • Connect Wiimote to play games on CarPC (so never get board waiting somewhere or stock in traffic!)

    Detail: http://debii.curtin.edu.au/~pedram/t...-upgraded.html

    Demo 1: Music, Video, Remote Control, GPS


    Demo 2: Playing Super Mario Kart on Zsnes (Super nintendo emulator) using Wiimote (Wii Remote) in the car!


    UPDATE 8 March 2010 *******************
    Spec (I bought everything on ebay):
    7" VGA TFT LCD Touch Screen (Size of this LCD match my double-din slot, Lilliput is quite big)
    100M 2.4G Bluetooth USB Dongle Adapter
    3 Ways Car Cigarette Lighter Charger Adapter
    Cassette Adapter (not enough budget to but Amp )
    4 PORTS USB 2.0 HUB HIGH SPEED
    DC-to-AC Adapter (doesnt work I get rid of it and instead I bought CNX-1900 from mp3car store)
    USB 2.0 A Male to Female Extension 2M
    USB PC Computer Remote Control (Got from ebay for $1)
    3G Mobile Broadband Internet Connection

    Win XP SP2
    RideRunner with Elite Skin
    VLC and Winamp

    Problem 1:
    I got problem with DC-to-AC adapter so currently laptop is working on its own battery. I cannot connect both touch screen and laptop to cigarette lighter at the same time... touch screen frequently get on and off... thinking to buy a DC-to-DC adapter for laptop but not quite sure to get same problem! any suggestion?


    Solution:
    70Watt Dc-to-Ac adapter does not provide enough amp for my power hungry laptop (19.5V , 6.15A) so I use CNX-1900 instead of that which work perfectly. it also have auto-power switch on/off feature for laptop.


    Problem 2:
    currently I got little bit flickering on my LCD. I power my LCD using cigarette lighter. does this problem happen because of wiring? if I connect my LCD to CNX-1900 would its flickering stuff be gone?



    Video:



    Photos
    (sorry not very good quality):




    Filled the small gap on top with some sort of material I found inside LCD box, it was soft and while, I use a marker to make it black ...


    Cassette Adapter for sound input to the car audio system.




    DC-TO-AC adapter (GOT RID OF THAT! change to CNX-1900 also I get rid of laptop power brick after connecting to CNX)





    Wiring Audio, USB and VGA cable to the trunk from driver side.






    CNX-1900 just shipped!


    Battery cable, fuse and distributer (terminal)


    Wiring from battery cable to the trunk


    CNX-1900 ignition wire (yellow) connected to cigarette lighter positive cable


    Distributer to connect battery cable to CNX-1900 power cables.


    PC Infra-red remote controller, very convenient and handy. got all the function you need for car pc. highly recommended and more importantly quite cheap $1-$3


    Pictures of mounting in trunk will be added soon. currently thinking where to put? any idea?

    What exactly isn't working about the DC-AC adapter? Judging by the size, it might not be supplying enough power. I would suggest getting a DC-DC power supply for the laptop. I don't know of any models or links off the top of my head, but they make universal car chargers for laptops with a switchable voltage/different size plugs/etc.

    I second that... Remember that power inverters for cars are rated at PEAK output. They can't put out that amount of power constantly. I ran into this issue once when I had a laptop in my truck and bought a 120w inverter and I could either charge the battery with the laptop off or run the laptop if the battery was fully charged. Couldn't charge and run it at the same time. If you want to use a power inverter I would look 200+ watts, but a DC-DC solution would be much better and more efficient.

    The problem is the DC-AC adapter cannot give enough power (watt) to the battery. so the laptop cannot run without battery inside.

    I checked out some universal car chargers for laptop but apparently all of them are not suitable for my sony laptop. on the brick the output voltage is 19.5v with 6.1amps... most of universal car chargers provide at most 5amps. am I right?

    I m thinking to buy a Carnetix CNX-P1900 (140W), do you think with CNX-P1900 I can provide enough power for my laptop? (19.5v, 6.1amps)

    Power problem

    hey man I agree. DC to AC is messed up. Think about it u r going from DC-AC-then back to DC. just use a universal laptop adapter which is better and wont mess up your battery or alternator. Here is a link to a cheap universal charger for cars on ebay

    Trust me DC-DC is way better

    hooray! CNX-1900 works perfectly with my laptop.
    I updated some pics and currently put the laptop into the trunk. I got two issues:

    1) any idea on how to mount laptop in trunk (I got sedan)
    2) currently I got little bit flickering on my LCD. I power my LCD using cigarette lighter. does this problem happen because of wiring? if I connect my LCD to CNX-1900 would its flickering stuff be gone?

    Any ideas? help?

    If you are trying to get it completely out of the way, is there any way to attach it to the underside of the rear deck? By "the underside of the rear deck", I mean the trunk side of the panel that is beneath the rear windshield.

    Also, sometimes in cars there is space between the spare tire and the lid that goes over it. Usually this space is just filled by foam, which you could easily rebuild with a couple boards.

    I got some space in read deck similar to the post here for Corolla 2005
    http://www.mp3car.com/vbulletin/work...tml#post524506

    but not sure how stable is it to mount it like that.

    the space around spare tire sounds interesting I ll check that out and make some photo . Cheers.
