    Yup, using that allready... just confirming the dimensions for the 479-socket, cpu and NB by Intel specs.
    The rest isn't all that important (give or take a tenth or two, millimeter that is) so I'll measure them manually if I need any (VGA board for example).

    I'll post it when done.

    What're you planning on using the 3D image for?

    Well, you know, some use posterboards... some use Solid Works

    I'm designing the case and heatsinks for the heatpipes so I want to make sure everything fits.
    My goal is to fit everything inside the case, in a double DIN space, so rather than going by trial and error I'm doing it this way instead.

    In a standard double-DINwith the depth of a standard head unit (aren't they around 180-200mm)... it's going to be close.

    I don't know what the specifications say about the double-DIN sizes,
    but in my car (SAAB 9-5) I have a bit extra room so I'm hoping it'll be enough.
    The aluminium housing for the TFT is already beeing manufactured so it must work

    I'm OK with pictures for now, just thought I'd ask about 3D drawings before I started so I didn't waste any time on things allready available.

    This is a rough idea for the case with the MB in it

    Yeah, I'll be using the P1900 and by the looks of things I'll have to squeeze it in on the right wall, just above the CPU/NB or maybe above the soundcard.

    It's quite obvious though that if I'm going to be able to do that I'll have to ditch the case (Carnetix that is) and just install the PCB.
    If the cooling is critical I'll also have to relocate the regulators to the lid of the case (big heatsink ) but that's something I have to check with Mike@Carnetix.

    I'm real excited for you, this sounds like it can def happen.
    I don't think you'll have an issue w/ cooling as long as you have the fan cooling the unit; you might even ask Mike if one fan would suffice to cool the PSU and the CPU since their quite low draw/heat.
    I was looking at integrating the unit in a similiar case but the display solution is the only drawback. If you're gonna have a computer in the din case you might as well have the display there as well.
    If you nn any info in regards to the LV let us know. I think we've kind of talked about most of the dis/advantages of the mobo and PSU.

    I'm quite excited myself since this has been my original plan from day one, and SolidWorks makes it so easy to try things out.
    The thing is with the cooling, I want a fanless solution and since I don't have the knowledge nor the fancy software stuff to do the simulations there's only one way to find out.... test it

    Oh, but the screen will be there, as you say... what's the point of integrating it all if you don't have any screen in it ? The initial version of the front panel is fixed, but I think I have a solution for one that swings open too.

    Yeah, the biggest setback for me was the lack och -12V on the PCI port.
    Commell LV-671 blues
    Cost me about $70 to return a fully working MB (besides some soundcards giving low volume) and all I got in return was a burnt up MB But hopefully their little "handywork" will be OK and I'll solve the -12V by making a -12V regulator that I power off the P1900.

    Has anyone tried to embed a picture into the bios? I loved how with the epia boards you could show a picture during the post. Has anyone been able to get that to work? I've edited the bios with some programs, but I am too scared to actually flash it...

    Wow dude!
    That'd be freakin' cool man, if u get that happening!
    How come you're able to do all these things, what do you have a high-tech shop to crank all these goodies at??
    And where do u get all the materials!?

    This sux!!!
    I have a major issue, was trying to fix the annoying flickering on the monitor, but the only way to bypass the cable and use a thicker gauge was to cut into the cable.
    Well, all hell broke loose, I think I messed up the cables and there must be voltage going through the video input.

    You may be wondering how could've I've been so retarded; well the cabling in the VGA monitor is kind of complicated and I guess I screwed it.
    The point is that the LV671 won't boot. No bios, no beep, the cdrom lights up for about 5 secs and then it freezes while the fan is spinning.
    Now, I'm freaked and I'm scared of touching anything. I'm traumatized.
    This blows u know what! I really can't believe I could've done something like this!!

    I'm not sure that you could with this board's BIOS...

    Usually the BIOS routines programmed by the manufacturer have to call certain functions to load the full screen picture.


    The one exception to this is the EPA / Energy Star logo image that is already stored in the BIOS - use a BIOS editor tool to replace the logo.

    The image would have to be a fairly low size and color depth, I think.. maybe as low as 16-color.


    And if you're worried about flashing a corrupt BIOS, you may want to look into a product called a BIOS Savior. Google for it.

    Essentially it's a backup BIOS ROM chip that you plug into the board, and you can switch between the primary BIOS ROM chip and the backup with a switch.

    Hi guys,

    Inspired by what you guys have been working on, I've decided to purchase one of LV671 myself. Using 1.5Ghz Banias processor, this thing is faster than my other desktops. So far, I've only got Intel 2200BG(These don't come with the antennas.. ahhh!!!) and a old 20GB hard drive and a slim dvd drive on it. I am planning on getting LCD panel to work. I only ordered the connectors. Thanks Giuliano! Looks like this is going to be an adventure since all wires are red. =P I do have a data sheet for the panel, but I am not sure what I am going to do for inverter. For some reason it's got ten wires that goes in to the laptop. Multiple power and grounds? I don't know yet.. =P When I get those connectors I'll try to trace the circuit and see where I end up. I gave up on finding 7" LVDS wide screen monitor, instead I decided to go with 12.1" (LTN121XF-L01 Samsung 1024x768) panel since it was the cheapest one available at the time($15.50 on ebay). I own a 2002 WRX wagon, but I don't have the guts to do what Giuliano is doing. =) I'll probably get a short panavise arm and attach it on the computer case.

    I've noticed that you guys are working on power supply. I was wondering if you guys thought about this alternative. Look at this laptop external battery.
    That laptop battery has an option to choose the voltage between 16 and 19volts. Both are within the range of LV671's voltage requirements. It's got plenty of battery so, you might be able to put your computer to standby mode rather than shutting it off. Engine cranking is not going to be a issue at all. Have that battery charger hardwired to cigarette lighter and it will be charging when you drive, (2002 WRX will cut off the power to cigarette lighter when the engine is off). I am a bit concerned about charge rate of this battery though.. Would this thing charge faster than what you use? =) On ebay there are alot of cheaper 12V batteries available too for external laptop battery, but it's capacity is small.

    Do you think the batteries will work? I've noticed in the manual it states that this board doesn't support battery mode, but I doubt it will be the case for external battery... although it will drain the battery at the full rate. =)

    Good luck guys. Let me know if I can help out some way.

    Yeah, the Pentium M systems provide a pretty good performance for the price.. and still run pretty cool, temperature-wise.

    So far, I've only got Intel 2200BG(These don't come with the antennas.. ahhh!!!) and a old 20GB hard drive and a slim dvd drive on it.
    That MiniPCI WiFi card uses the Hirose U.FL-R-SMT connectors on the board for the antenna, which mate with the U.FL-LP-066 connectors on the cable.

    You'll need two antennas (or one antenna with two wires), as this board has one for transmitting and one for receiving (a good thing).

    Here's the operating specs for the card from Intel:

    http://support.intel.com/support/wir...0/specs.htm#bg

    You can get antenna assemblies that are pre-made, and can be either glass-mounted, roof mounted (magnetic), or permanently roof mounted (drill/cut).

    I don't have an example right now, but I'll look one up.. I've seen them before.

    Send me the data sheet or post it here, and I'll see if I can't work out a pin mapping for you.

    If we can work out a pin mapping, I'd recommend that instead of trying to make the cable yourself, that you outsource the job to a company.

    I've heard good things about Quadrangle Products from another MP3Car forums member - they made him a cable on the same day that the order was placed, and it was about $20.

    If I end up having a need for a longer cable, I'll have them make it for me.

    When I get those connectors I'll try to trace the circuit and see where I end up. I gave up on finding 7" LVDS wide screen monitor, instead I decided to go with 12.1" (LTN121XF-L01 Samsung 1024x768) panel since it was the cheapest one available at the time($15.50 on ebay).
    Yeah, standard-aspect (4:3) LCD panels are much easier to work with these days.

    And that's quite a steal for a LCD panel, if it is LVDS - but be warned, it's brightness is rated at only 150 cd/m / NITS, so you may have trouble seeing it during the daytime...

    Plus, no touchscreen..

    I own a 2002 WRX wagon, but I don't have the guts to do what Giuliano is doing. =) I'll probably get a short panavise arm and attach it on the computer case.
    Awesome, another WRX fan..

    The battery is a good idea, especially since it's a Lithium-ION battery, which can deliver quite a lot of power over time with no battery memory effect.

    Perhaps it could be used as a buffer battery, installed in between the car's main battery and the LV-671..


    However, the battery charger circuit probably wouldn't be able to keep up with the power demand while the system is running - the battery would run out of power sooner than the charger could supply power..

    Anyway, I'm buying a Carnetix P1900, saving $50 off of what the battery costs.
