    1st carputer: 2006 Audi A3

    Hi everyone,

    So I bought an Audi A3 2 weeks ago (my 1st car) and decided to install a car pc. I am a student so my budget was low but I still wanted a good system. I have learned alot from mp3car and decided to buy the following components for my carputer:

    1. 1.8Ghz Atom mini-ITX mobo - $107
    2. Aux addon to the current HU - $60
    3. 7" samsung touch lcd transflective + board - $166
    4. M2-ATX power supply - $50
    5. 4Gb DRR3 RAM - $37
    6. Holux GPSlim236 - had one lying around
    7. GPSlim usb data cable - $13
    8. usb wifi dongle - $6
    9. usb bluetooth dongle - $2
    10. usb slim/laptop dvd adaptor with case - $8.50


      The prices might seem expensive but it includes shipping to South Africa. All items were bought from ebay.

      I plan on installing the lcd where the ashtray is and the computer in the glove compartment. It seems like a tight squeeze. Any advice on this? I cannot install it under the seat as the space is minimal and the boot is a definite no.

      What do you think? Is there anything I'm missing?

      Thanks!

    looks like a plan.

    could you post some pics of the area you want to install the pc? that would help me get a idea if there are any suggestions i could offer.

    Thanks for the reply. Below are the pics of the area I want to install the carputer in:



    I would like a similar glove box setup as mrtopher1980 did (2006 Audi A3 2.0T). Below is his setup:


    I am not sure if he did any cutting of the glove compartment. Does anyone know the dimensions of his mobo (VIA EPIA MII1200)?

    ^ from what i can tell, the via is a mini-itx board, so the size should be the same, though, it looks like the pockets are the same size, so i think you might need to cut some material away(a mini-itx board is 6.7" x6.7")

    Ok, will see when I get the components. I am thinking of relocating the lcd as the gear knob gets in the way in terms of visibility. I was thinking to make the lcd slide out and tilt from under the climate control and thereby have the lcd as shown below. The slide out and tilt operation can be done manually.



    The problem is with the lcd flex cable, it looks too short. I would like to extend this cable but I am not very experienced in soldering. Another option is to make the lcd and the lcd controller slide out as one unit. Any suggestions on this? Thanks again.

    I'm thinking of modifying a cd-rom drive for the lcd slide and tilt mechanism. Any thoughts on this? Any ideas or input would be highly appreciated. Thanks!

    More fans?

    Ok so I have installed my pc into my glove box as shown. It is a snug fit. I am just wondering if one fan is enough. How hot will my atx psu get? Also note the processor is an intel atom so it doesnt get that hot. Comments and suggestions would be appreciated. Thanks

    don't know how i missed the last couple of updates.. or how no one else has said anything...

    for the screen, i have seen some mod a old cd rom tray for this, though the travel is not long enough for a 7" screen, so it might be a little difficult. you could combine this with a second idea for a half-motorized setup(cd tray pops up enough to grab the screen for the rest of it's travel).

    second idea-- i remember reading of one person use kitchen-drawer slides for a manual pullout screen. if i remember right, it was a mid 90's ford ranger/explorer...

    as for the heat issues-- i ran one of those motherboards for a while, and they have very little heat. that one fan should be fine. and while i have not used that specific power supply, i do not remember ever coming across any builds that had issues with the units generating any heat.

    Thanks for the prompt reply.

    With regards to the slide out lcd, I have modified an old cd rom drive as shown in the pic below. I had to change the motor and add a geared system so it can handle the load. I have 1 problem tho, the motor's rpm is to high and even with the gears, the cd tray slides out too fast. Is there any other way of reducing the motors rpm without adding more gears?



    Also, in order to allow the lcd to tilt, I will use spring loaded hinges so the lcd will tilt as it slides out. Do you think this will work?

    it looks like you have pretty much rebuilt the cd drive-- so does that mean you are also using some external controllers as well?

    all i can think of to correct the speed would be a variable voltage regulator-- that way, you are limiting the amount of voltage the motor has to operate. if your still using most of the cdrom electronics, i am not sure how the other components will react with that-- they might require 12v and 5v directly off the 4pin molex..


    i think the spring loaded display should work fine-- try it first, though i am thinking that you might want to add some small strips of sacrificial plastic along the back of the screen and top edge of the opening to prevent damage and/or excessive wear to the screen or opening.
