    Lightbulb Carputer on a BMW E36 Cabrio

    Dear all, I'm just thinking about installing a carputer in a 3 series E36 Cabrio. I was thinking about placing the pc in passenger's compartment under the Airbag. Looking in I saw a sort of 12 V alimentator in the compartment. The question is: can I use it to supply power to my PC? And if so, what kind of adapter should I use?
    Thank u
    Tommy

    whats a 12v alimentator??
    but the answer is probably not. A car's 12V is rarely a true 12V. It drops when your cranking the motor and rises when its running from the alternator. Your PC will need a regulated 12V, along with 3.3V and 5V circuits. If you can find a DC-DC converter with a wide input range (8-16V), that might do the trick.
    My first carPC!

    Celeron 633MHz - 10GB Seagate - 64MB PC100 - Win XP

    Soon to actually find its way into the car!

    I discovered is a socket for emergency lamp, witch is connected directly to battery. Would it work if I use an ITPS? Thanx

    This afternoon I'll do the pics.Hey enforcer, my car is just like yours! It's a 1997 E36 with black leather. When I looked your pictures it seemed my car!

    Another problem is that I don't know how to remove plastic parts to put in the wires. Sorry but I'm a real newbie I haven't ever touched a car!

    Thank you

    There are a few things I would be concerned about placing a PC in the glove box on an E36. First, I don't think there's much air flow there - it might not be much of an issue; however, I would still be concerned.

    Second, the compartments on the E36's are not known for their longevity, at least here in the states. The doors tend to sag due to poor support, and while I wouldn't expect a PC to exaggerate that problem it is something worth considering.


    Pics 2 and 3 are of the rechargeable flashlight socket. I'm unsure of the top of my head how much power is available there, but I'm pretty sure you wouldn't want to power your PC off of it.

    Pic 4 is the light for the glove compartment - it is most definitely a low voltage connection, so not very feasible for powering a PC.

    Finally, at least on E36's in the states, the battery is in the trunk, boot, ie the back of the car For me, it is on the passenger side of the trunk, under a plastic cover. This would allow for easy placement of a PC in the trunk, although you would need to run signal and control wires through the interior.

    Do a search through the forums here, there are plenty of folks that have done this type of thing on E36 and E46's with great success. On a related note, I recently upgraded to a sub and amp for my audio system and found that running the cables through the E36 interior wasn't quite the nightmare I expected....

    Thank you for your answer. So that's where the battery is! Tonight I'll check!
    So where do I have to plug the carputer? Directly to the battery?
    About passing the wires: the fact is that mine is the cabrio model, that means that I only have 2 doors and it's not so easy to pass the wires!

    OK, first off, I agree about not putting the PC in the glove compartment. And shadowpuck has described those connections correctly.


    You have some decisions to make, many will be determined by your skill level (or that of your friends).

    Firstly are you going to use a standard PC or make one up from parts?

    How are you going to power this? using an inverter or a 12vDC-DC PSU.

    What sort of screen and where it is going to go.

    Oh yeah, and how to run the cables.

    and there are many more

    running the cables can be done in a fews ways, depending on your knowledge of the car.

    If you are prepared to remove the front and back seats and lift the carpet, that is the best way.

    otherwise you can remove the rear seats (this is easy), and try and fead the cable to the centre console under the armrest (this is what I have done).



    When you are ready to go just ask any questions you want.

    I was thinking about using a mini-ITX PC and a Lilliput 7" with TS.
    Is it correct connecting the power supplier (12 V 200 W) directly to the battery, then the PC with ITPS to the power supplier? Or should I connect anything between the battery and the PC?
    Enforcer do you have any pics about how you plugged the PC to the battery?
    Sorry guys if I'm boring u, but I can understend quite a lot about computers and quite nothing about cars!
    However thank you
