  • Carputer in '03 Vette - plz suggest

    New to the forums here. Not new to computers.

    Lately I have had a wild hare up my a** to put a carputer into my brand new 2003 Corvette Z06. Yes this is my first (Vette and carputer), and no it is probably not a good idea to cut my teeth on my new 45k car but bear with me, I am pretty handy...

    So here is what I think I want so far. Please review and suggest. You'll notice I have far more questions than answers here...

    Display - Lilliput 7" Touch Screen or the new Pixelon being looked at in LCD/Display discussions (XGA) - I will most likely pick one or the other

    M/B - Via MII
    most likely, but open to suggestions (see problems below)

    Case - determined by M/B and possible slot problems mentioned below

    Wants:
    • Wireless 802.11g
    • FM/AM tuner card
    • TV card if it is possible to do this without the boomerang (or similarly large) antenna (anyone know?)
    • ODBII hook-in (to control computer and see instruments, etc.)
    • Large Hard Drive - I have seen threads here that say standard mechanical HD's wont survive vibration/G's (suggestion was use flash or similar instead), that they can survive if you use RC car shocks, use laptop HD as it is better suited for rough handling, and some that say a standard hard drive with nothing special works fine. All I know is that plain flash won't work it wont hold enough data. Any guidance?
    • keyboard - initially I thought I would only use an on-screen keyboard with the LCD touch pad. I have since reconsidered using IR, problem is that IR receiver is large (I want this carputer to look 'factory' so only visible component will be LCD). Suggestions?

    Problems I have found along the way:

    Other than those mentioned in 'Wants' I require am/fm card and wireless NIC. The MII has only 1 pci slot. I would also like to have, as mentioned above, possibly a TV tuner card... Is there any good suggestions? Possibly a combo card or a better M/B with more slots? or USB devices?

    Wireless NIC, btw, will allow me to hook up home network to car to download MP3's, movies, etc.

    Secondary problem: I am also wanting to integrate my car Heat A/C controls and remove that from the dash if possible... I know in the Vette it is all electronic (no vacuum) so it should be possible with a PLC. However there appears to be some processing relating to temperature (you set a thermostat on the A/C controller). I am not sure if this processing is done in the Heat A/C head unit, or if this data is passed back to the main computer and processed there... Any suggestions on that?

    Thanks to you all for your educational posting thus far. I would have never considered doing this until I came across this board.

    First I don't know anything about how car electronics work. IE the electronic ac controls. Though I am sure that there is a way to move those functions to the computer you are going to be building. Just have to be creative and know some programming and or electronics.

    Second. Scrap the motherboard. You are going to need one with more PCI slots on it. You will need at the minimum of 2 slots. That if you can find a card that is a am/fm tuner and a tv tuner in one and one for the wireless network card. Thats unless you can find USB solutions to those components but I still don't like the processors that they come with. Plus after looking at the specs of the processors that via is comming out with I am not all that impressed with them. Go with AMD or Intel chips. I think you will be happier. And going with a MicroATX motherboard or larger allows you more upgrade options for new equipment as well as upgrading the processor depending on how good of a motherboard you get.

    Don't know about TV tuners antennaes so I can't help you there.

    I don't think you can find a large hard drive in a laptop form.

    There should be a number of solutions for you when it comes to your ODBII diagnostics. Thats as long as the Vettes are ODBII which they should be. Check the ODBII forum on this board for more info on that.

      Thanks for the input... Any suggestions on the M/B? Problems I see with those involve adequate cooling (the Via boards are more forgiving... of course thats prolly because they can't process as quickly .

      On HD I would actually prefer a full size drive. I don't know that laptop hard drives are any more resiliant than regular HD's even though I have heard that stated here. In fact my experience with using them to power PC's at home is they are not, at all. Most of them died within months (perhaps it was the 24/7 usage?).

      Thanks!

        For the motherboard consider going an underclocked Athlon XP-M. How is the climate where you live? You may need to do a lot of cooling customization even underclocked.
        Never be afraid to do something yourself. Remember - amateur built the Ark, professionals built the Titanic.

          I would think cooling issues depend on where you live. I will be building an el cheapo computer to put in my car because in the summer it reaches between 150 and 120 degrees here. Course if it can stand up to the heat then I will build a better one. There are people here that are running the AMD and Intel processors that are more recent than whats on the Via boards. Just make sure you have enough fans.

          As for what boards. Not really sure. Its been sometime since I looked at motherboards so I don't know what changes have occured. Like I said I will only be building a cheap one so I haven't done that much investigating. Course first you have to decide on a chip

            laptop drives can typically take a higher G load, but only while not in use. As far as the regular 3.5" drive, I would recommend just buying some 1/4-1/2" urethane grommets and build a mount in which they can be used between the drive and the metal chassis. Ths is usually enough shock protection as I am sure you dont hit speed bumps/road humps as 30+ mph. Another thing you may want to consider, due to the warm climate, is installing heatsinks on your motherboard chipsets, RAM, and video card. I usually do this in my desktops I build, as well as a fan blowing air across the hard drive lengthwise. Be sure to tie wrap all your cables, install your intake fans as low as possible (I am building a stealth intake duct for mine) and use an additional exhaust fan besides the one in the power supply. (Make sure it is blowing air out, and not in)

            That should help you with any heat concerns. As far as the motherboard goes, look around at the different manufacturers and see what you like. There are a lot of them on the market, so you have a large selection to choose from. My personal reommendation is to look for the following when selecting a board:

            1) Space for mounting additional/alternate heatsinks on the chipset
            2) 4x or better APG slot
            3) ATA133 for your primary IDE channel
            4 DDR 333 or faster (PC2700) memory slots and split your memory bewteen them evenly
            5) PCI and AGP slots that will not "share" a cardslot in your case


            Well, I think I have rambled on long enought.

              BTW, I will be running a Celeron 2.8 and my car gets about 140+ in the summer here! (Black 300ZX in south Texas)

              Just use good heatsinks, duct/direct the airflow and use high quality thermal compound (Artic Silver)

                The processing is done in the climate control unit.
                It has all sensors hooked up directly to it, and it controls vacuum solenoids and motor controllers directly.
                It is, however, a Class 2 device. It almost looks like the A/C compressor request is a Class 2 command from the climate control unit to the PCM.

                  I have a similar setup to what you are suggesting in that I have a Via motherboard and Lilliput touch screen. I use a D-Link USB wireless device to download MP3's and movies from the house and will soon be putting a D-Link USB radio in place. Thinking about it, I believe the D-Link radio is FM only.

                  When I started my carpc project I found that what I originally thought I wanted I ended up changing to something different. The Via board with built on CPU is fine for most needs in the car i.e. video, MP3's etc. And runs fairly quietly and cool. I took the view that I would use USB where I could and save the PCI slot as a last resort. It is possible to get a riser card to provide 2 cards from the one slot if needed so you don't have to go to a larger board especially if you don't have much room for one.

                  From experience of my project, I would think of the more practical side of things from where are you going to put the PC? This may limit the size of motherboard to go for. Would the hard drive be mounted in a different location to the motherboard? This may mean long cable runs between the two and therefore another limit on hardware you purchase. For me I am thinking of using USB2 CD/DVD drives to the computer (Disk drives in the front, computer in the back!).

                  The other big difference I never thought of until I started building is software. I have now settled on Mediacar for the front end screen. The latest release now supports the D-Link USB radio and hence my selection for that device. It's amazing how your needs change based upon experience on this board! I started off wanting Digital radio.........

                    Thanks all for the great responses... I live in Dallas so pretty comparable to South Texas.

                    Magpie get outta my brain! I concur with you on all you got but I am concerned about the sound quality from a USB device... I guess a carputer will never be a Sony in that area but I had thought an internal card might be better? Dunno...

                    On the M/B I am limited by space. I know I will have to do a mini-ITX or smaller. Not a lot of room, but that fits neatly into the trunk pockets. I still lean towards the VIA MII b/c of heat and cost. My car is black as well as being in Texas, so even with the VIA I know I will need to put in good cooling. I may start off with that and if it doesnt have enough horespower to play videos, etc. I will upgrade. Stability and cost are most important at this stage.

                    A 2 slot setup would solve my problems. I could also USB the wireless...

                    Will use the hard drive mounting ideas and use one of my full size 30gb to start with.

                    One more thing I forgot to mention. I wanted to put an XM PC receiver in there too. XMPCR looks like what I need, but alternatives are always appreciated!

                    Thanks again guys

                      Creative labs has made alot of money off of their USB sound cards and its my understanding that they do a pretty good job. Have you thought about speakers for your computer. Or are you going to route it through the car stereo or an amplifier.

                        OK, So I re-read my post and I guess it does sound amusing

                        Sound through USB is not a problem as it's only used to send digital data. The sound processing takes place in the boxes you add to your system. I have a Sony XA-300 auxilliary input box for my SOny head unit. It comes with USB input and appears to the PC as a USB sound card. The sound quality is fantastic with no chance of interference, whereas audio cables from the PC to headunit are nowhere near as good.

                        The only downside to what I was suggesting is the D-Link USB radio. IF there was an alternative I would probably go for it but as everyone is building fantastic front ends for it in their software it's hard to move away from it. It's not USB that would put me off purchasing. Take a look through the forums and you will find lots of people using it.

                        I can't wait to see the final thing. I have no idea if your Aircon control are going to work! But if it's a case of replacing switches then this should be fairly straight forward. I think displaying the feedback from the car to the PC is going to be your hardest task.

                        Good luck

                          Magpie, thanks for the thought on the XA-300. I will be looking into this.

                          I am giving up on the AC controls through the PC. Probably just physically move them down in the console to make enough room for the screen. I am having difficulties b/c the dealership said that the AC controller unit accepts pressure readings from the high/low side of the system to determine the compressor cycles, rather than this being done somewhere else in the computer system. This is more than I am up to in programming... Too bad.

                          I know I could also tear apart the controller unit and hard wire into the switches directly instead, but thats too much of a hack for me to feel comfortable. So instead I found a company in California who will cut/modify/mount the LCD into the center console, lowering the AC controls into what is now the ashtray. They quoted 5-800. Hope I am not getting ripped but don't know any other way to make it look proffesional.

                            I have a carpc in my '99 C5

                            I bought a factory deck adapter with the EQ mount in the bottom.

                            Cut off the EQ mount so just the Din is at the top of the dash.

                            Mounted a Kenwood 7" motorized screen there.

                            Then cut the plastic bar between the factory HU and the HVAC.

                            I retained that plastic bar which I am currently in process of re-molding right under the Kenwood so it is between the Kenwood, and my Xenarc touch screen. I bought the Xenar before the Lilliput was available, but Lilliput should be fine.

                            I moved the HVAC to the location of the ash tray by simply using a dremel to remove the ash tray. It fits great.

                            The Xenarc is where the HVAC used to be.

                            You can probably put the Lilliput where the factory HU is, move the HVAC to the ash tray, and put an aftermarket deck where the HVAC is currently.

                            On corvetteforum.com there is a ZO6 owner who moved his HVAC to the headliner above the rearview, but he installed a 10" screen.

                            Moving the HVAC shouldn't be a problem.

                            Also, FYI, if you are interested in a satelite radio, you can mount the antenna inside the rear bumper above the license plate and it will see right through it.

                              Definately a huge rip off, there is a guy on Corvetteforum.com doing it for $250
