    Kibble's Kar Komputer Konstruction '01 Infiniti I30

    Well after being here for a bit. I finally got around to posting my work. Here's most of the stuff I'm using in my system: The mobo is a Gigabyte GA-MA78GM-S2H, M4 ATX power suppy, a Polstar GPS receiver I removed from a Parallax GPS module and soldered to a board I made with power injector for an external antenna, a 80GB 7200RPM SATA II hd, and a nVidia geforce 7300GS card that I may or may not use, depending on how the system behaves with the built in ATI 780g chipset. The Heatsink on the processor is not actually the one I'm using now. this pic was taken before I got the new one.



    A couple of pics of the case I made. It's not complete yet, I still need to file down some of the corners where I welded the angle aluminum that I made the frame from and make some panels to cover the sides. the tray that the mobo sits in is also made out of aluminum that I bent to size on a brake. I drilled and tapped the holes for the mobo standoffs.




    A couple of pics of the rear and front of the case.




    A couple of pics of what it looks like mounted in the trunk. No that sub above the PC doesn't affect it at all. I keep getting comments from people about that.




    The heatsink for my processor, an AM2 Athlon 64 X2 5600, is a Dynatron A48G 1U Server Heatsink that measures a little less than 3cm tall, including the fan!




    For a monitor, I'm using a 15" NEC monitor that I modified to make a touchscreen. I removed the touch panel and touch controller from another 15" monitor that didn't power on and was a bit bulkier. I had to drill and tap a couple of holes to be able to mount the touch controller to the new monitor.




    The controller uses 5V and an RS232 serial port for data communications. I poked around with my multimeter to try to find a point on the LCD controller board that would output a switched 5V that would only be available when the monitor was powered on. I found one.




    The old monitor that the touch controller came out of had a 9 pin D-sub port for the serial connection to the touch controller. Conveniently enough, the monitor I mounted the controller on has a 9 pin mini DIN connector on it. I wasn't planning on using serial data, though, to connect it to the computer. I wanted to adapt it to USB. What I did was buy a serial to USB adapter and take it apart so I could just use the board. I soldered some wires with an IDC connector on one end to plug into the touch controller and soldered 4 wires to the USB side. Then I covered the whole assembly in heatshrink to protect it.




    I removed some resistors and capacitors going to the 9 pin mini DIN connector that were used to interface the connector to the onboard microcontroller for the LCD, I wasn't gonna use that connector for it's original purpose anyway, it used to go to some external box that was useless to me. I soldered the USB data lines from the adapter to the pads leading to the connector where I removed the resistors and capacitors from.





    I had to modify and cut the monitor enclosure a bit so that the whole assembly with the touch panel would fit in nicely, but it looks pretty good! Still working on a mount for the monitor which I'm almost done with. When I have that done, I'll have more pics.

    I like the 'open frame' case, plenty of airflow

    Yes, you should search... and Yes, It has been covered before!

    Read the FAQ!

    I'm not planning on keeping it open though. I'm gonna make some panels with vents and small fans in certain areas so that the air flows over certain components.

    Finally got around to putting up some more pics of progress. These are basically just pics of what the mount looks like and how it's put into the car. I tried to make the mount so that it wouldn't require cutting of any part of the trim in the car. It bolts down to 4 places where screws and nuts were already present.

    The mount holds the monitor really stable and despite the monitor being really heavy, it doesn't bounce around much. I have two hinges on the monitor; one so that it allows the monitor to swing over to the passenger side and another that lets you adjust it so it faces up more.

    In one of the monitor pics, you can see my ghetto DVI cable going into the monitor. That's still in progress.

    The only thing not shown here is how the top part of the mount goes together with the lower part. I forgot to take pics of that.
