    '95 Geo Prizm LSI newbie...

    Hi everyone...love reading all the posts but my 56k modem is killing me here in terms of finding all the answers with the search utility.

    Is there anywhere where somewhere has put together a sketch/diagram of how everything goes together in all possible configurations? What about a checklist of all items needed?

    This all started with my cassette player busting and me thinking of replacing it. Now it has grown into, hey put in a carputer. But if I remove the unit completely and it appears to be a double DIN unit, then what do I do? It seems as though I need a HU or amp to connect the PC to for sound output so I guess I will buy a simple single DIN cassette HU as the means of doing that. Then that should leave me another space to put in one of those dww in dash non-motorized 7" Panasonic LCDs. And then I I could build or buy a pre-built unit and mount it under the passenger seat (don't know if I'd have room in the glove box)...unless I could dispense with the HU and mount a small enough unit righ in dash? But then what about this whole OPUS entity deal? Where does fit into the whole system? Could I dispense with it and go with the on-board one I seem to recall seeing? And what if I want a lot of units to power (i.e.: TV tuner, DVDRW, HDD, and the LCD) is the 150W OPUS enough or is their new forthcoming 220W one sufficient?

    Thanks guys.
    PS: Another alternative I was tossing around in my head was to go the laptop route given that I need a new laptop...so I could spend more to outfit with everything extra I might need for the car, given that I could take it in and out of the car...

    And what about heat and vibration? I recall seeing some guys saying they mount the HDD vertically but was that for a 3.5 or 2.5 unit? What are folks experiencing in general out there?

    It would be real nice if there was a DOs and DONTs list out there (i.e.: is it ok for box and OPUS to be on top of one another or side by side under seat). Or a flow chart of paths leading you to what you can and can't do given your desires.

    For me at a minimum, I want TV, HDD (for MP3), DVD playback and Internet connectivity via WIFI.

    Hey guy,
    I don't think you're gonna find the type of FAQ you're looking for...carputer's are not like regular car audio components in which they are designed for the car, interconnect with standard devices and are ready out of the box. There are litterally thousands if not millions of combination of what you can do in terms of hardware, software and configuration.

    Though they've come a long way it still requires a lot of custom setup, patience, and understanding of the concepts. I'm still a newbie myself but I've been a lurker for a long time and have a good understanding of PC's and car audio. I suggest doing a lot of lurking a research and then just dive in.

    To answer some of your questions:

    Power requirements: All depends on your components. The biggest factor is are you gonna go with a mini-itx or a full blown p4 atx system? Big power difference. Heat, vibration, cold: all affect your system, theres no guarantees. Hard drives were never designed for use in a car or outside of room temperatures. I've had hard drives freeze on me back in the day. But now-a-days they are built more rugid and can usually take it.

    You don't need to buy a tape deck. You can take the outputs of a carputer straight into an amp to drive your speakers. However if you want either tape or radio, get an HU. Though they do make radio interfaces for PC, they aren't good. You could substitute XM though.

    Get broadband. It's the only way, brother...

    All possible configurations?!?!? There's no friggin' way...
    When you figure that you can use ANY computer with ANY components, there's no way a FAQ could be compiled for that. Just look at the possibilities for hooking up audio:
    - Soundcard into AUX on a headunit
    - Soundcard directly into amp(s)
    - Soundcard into a FM modulator
    - Soundcard into a DSP

    I highly suggest you do some searching here to get an idea of how to accomplish what you want to do. Everyone's wants from their CarPC are different.

    The Opus is a power supply. It replaces the ATX power supply for your PC. You run wire from your battery to the Opus, and it connects to your motherboard and/or peripherals.
    And if you decide to go without a headunit, you'll need an amplifier.

    That's another option. Again:

    It will yield loads of answers.

    This hobby is so in its infancy that you need to do some experimentation...
    Have you looked in the FAQ yet?
    How about the Wiki?



    Under normal circumstances, a signature would go here.

    Tex, you've got a PM w/a 'kit list' it's a great start..

    IMHO: If you're serious 'bout the laptop route, I think it's as good as any.. and keeps you from buying a 2nd system.
    Further, ... I'd recommend that:
    <> You buy TWO docking stations
    <> get plenty of HD space
    ... If well planned.. it can be a very smooth setup
