    QuantumPC

    Hi all

    OK, here goes...

    Long story short, I own a kit car. I recently reviewed a pre-production V9000 motherboard (EPIA) which I got to keep. I'd like to make a carputer out of it. Plan so far:

    Phase 1
    CD/DVD/MP3/Movie player
    Radio

    Phase 2
    GPS System
    Refill logging (petrol)

    Phase 3
    Environmental awareness Temperature sensors in engine bay, inside car, outside car, speed, wheel rotation rate, estimate load
    Voice Recognition

    Phase 4
    Networking (Wireless)
    Electrical system monitoring Light failure, battery status, charge rate

    Phase 5
    Engine Monitoring RPM, Fuel usage, emissions, 3-stage temperature sensor (Head, Block, Gearbox), range, water temperature, water pressure
    Mobile Phone Integration

    A lot of that is very optimistic, but it keeps the brain ticking gives somethign to aim for

    I was thinking of using one of the Cubix cases from M-itx / Linitx et al which as a 12V in connector. (link). The PC will sit in the boot and I am planning on running it off the rear window heater / washer which being a softtop car I have no other need for. Is it worth trying to get a regulator?

    For the screen I'm thinking of the 7" In-dash with a TS.

    The sound will be covered by the four speakers already in the car (the stereo will come out). Obviously I cant connect these directly to the EPIA so does anyone have any ideas as to how I could do this?

    I haven't got as far as working out sensors et al yet but I've found some helpful sites...

    I'm based in the UK which is going to be quite a pain for ordering things online...

    Anyone have any pointers?

    What exactly do you mean by "kit car"?

    You should look up OBDII dataloggers, if your car supports that. They are very easy to hook up and can give you quite a wealth of information for environmental awareness without the need for additional sensors. This also has a lot of Engine Monitoring, so these things can be moved up to phase 2 or 3. Some of your ideas however seem a little, well, not very useful for the amount of work that you'll need to put into it.

    What's your budget for all of this? Maybe then we can offer some you some pointers.

    You will need a regulator if you want to use that case and power supply that you mentioned, however if you did a search on this forum you would already know that (hint hint)

    A lot of the information that you are looking for is already covered in depth in this board, just try to use the search feature to figure it out. My FAQ might also help you, located here: http://www.mymp3car.com/MP3Car/mp3carfaq.asp

    A kitcar is a car you build your self, using components from a donor vehicle. In my case, an XR2 fiesta. Everything is kept apart from the shell, the rest goes into the fibreglass body. Highly customisable and great fun to drive

    I'll look them up, but I've never heard of them

    I just like to show off

    Cheaper the better, but the reason for spreading it out into phases gives me time to spread the cost.

    I guessed as much, however the key component isn't available in the UK without paying an extortionate delivery charge, I was hoping there was an alternative method.

    Yep, I was just seeing if there was anything in there that wasn't covered in the forums

    Since you're in the UK, you may want to hit the Mini-ITX forums at www.sfftech.com and see who can ship. I don't frequent that site (because most of the vendors are in the UK and I'm not ) but they seem to have some local guru/vendor guys that seem to be reputable.

    Re: QuantumPC

    As any installers will tell you, if you plan on getting a big system, do everything all at once. There's no point to finish an install then take it back apart just to add a piece of wire or cable. Panels will become loose, screws become stripped. panels get broken. To start, you should focus on the hard to achieve part first.

    There are tons of info for CD reading/writing,DVD reading/writing, audio, video,GPS, Voice Recognition, Networking (Wireless), char LCD display on the Internet. They are all easy to do and should not be the main focus of your project.

    Other components such as security integration, GPS tracking, electronic device control: door locks, windows, AC, lights engine starting and in your case engine stats are much harder to do and should be your main concern.

    As for Refill logging (petrol),Temperature sensors in engine bay, inside car, outside car, speed, wheel rotation rate, estimate load, Electrical system monitoring Light failure, battery status, charge rate, Engine Monitoring RPM, Fuel usage, emissions, 3-stage temperature sensor (Head, Block, Gearbox), range, water temperature, water pressure, you can try HKS or some automotive performance manufactures to see if they have a package for monitoring the engine stats on none OBD-II compliant vehicles and display them on a PC. The package will probably have A LOT of sensors that you have to install and hook up through out the engine bay. This is going to be your biggest challenge. If you cant find any, you're gonna have a huge headache and a lot of A/D converters and write a program to make them work.
    Cars made in US or for US after Jan 96 are On Board Diagnostic version 2 compliant. Version 1 is proprietary. This means that each auto maker has their own diagnostic system. Version 2 is universal. The plug is the same though there are 3 protocols ISO, VPW, PWM. This means that there's an OBD-II plug somewhere under the dash that can be used to hook up to an OBD-II scanner for trouble shooting check engine codes, smog codes and receive engine data such as you mentioned before. If for some reason you're lucky enough that your kit car is OBD-II compliant, you can just buy a PC OBD-II data scanner. It may not show ALL the information you mentioned above. But it will show the vital stats like speed, coolant temp, engine RPM, throttle position, engine load, air intake temp.

    Mobile Phone Integration - I'm kinda lost here. Are you looking for a way to integrate the cell phone to your PC to work as a hands free or so that you can use it to access the INTERNET or use the PC as a cellphone so you can use the touch screen to dial the numbers? The first 2 is doable. I don't think you can achieve the 3 one.

    power supplies and touch screen high resolution monitors have been beat to death on this board. For power supply, I'd recommend the Opus 150 watt because it has a built in shut down controller, over 90% efficient, operated between 7-18 volts. won't reboot your computer when you start your engine. Low voltage auto shut down. Be sure that you tell Kris that it's for epia M board. Since it's a kit car, you can mold a Gains 7" wvga touch screen into the dash.

    save yourself the headache from trying to build stuff. If you can get prefabricated components then get it instead of trying to hunt down parts, schematics and solder schit and burn down your kit car.

    Hi all,

    This project has yet to take off, but I'm now in a position to do so

    VIA have given me an EPIA MII motherboard and I have all the other parts I need except the screen.

    Are there any recommended UK suppliers for screens? Ideally touch-screen but I'm open to suggestions
