    Rather than using Cat5 or Cat5e cable, you might have better luck using Ethernet extension cables, which are 8 multiple-strand wires rather than 8 single wires. They're much more flexible, and are intended for installations where they'll need to flex.
    .
    If just enough is really good, then too much ought to be perfect.

    Yea I was thinking I might have problems like that, but my first VGA
    cable for my car was made form cat5, it held up for years, until I
    replaced it, I am guessing the cold makes the difference, the coldest
    its gets around here is just below freezing for a few days and back
    to warm weather, it seams to do that in cycles all winter long

    I found a 10 foot long female to female DB9 cable on Amazon.com for
    like $2.35 I am going to replace the home made one with it, I may still have
    to use a short extension cable to get an extra few feet or inches, but this
    should solve any potential wire problems I hope

    Got some parts in today, and got that DCL11 on order

    I got my Zippy EL-620 Mini Keyboard, Hub, USB cables, and PCI USB card

    Here is the cables running under my rear seat, split loom protecting them


    And the USB hub, fits perfect, arm rest lid even closes with the thumb drive
    plugged in on top




    I am trying to figure out a way hold the keyboard, and came up
    with using a flexible camera tripod, a Targus Digital Grypton Tripod
    I do want to replace it but it holds the keyboard ok

    I took off the camera head from the tripod, it unscrews, and used
    the center leg to wrap around the mount


    I want to use something to hold the keyboard like that, but that
    wont kill or hurt me in an accident, so I cant just use a metal plate

    Here is an action shot


    When I was sitting out there with the doors open bugs kept buzzing
    my keyboard, and about 5 to 10 managed to get around under the
    keys, so if you get an illuminated keyboard try for a red lighted one
    or keep your doors closed

    You're going back to the original meaning of the computer term -- you have to de-bug the keyboard. Good history lesson!

    a bolt the same diameter, you can make a hinge that only moves when
    you want. The freedom to move is determined by how hard you tighten
    down the nut. To keep it from squeaking and to add smoothness to the
    motion, use fiber or copper washers (or, best of all, a sandwich of
    copper-fiber-copper) on each end. Use a second "keeper" nut to lock
    it in place, and away you go. The hinge we used was under $6 at
    Home Depot, and it's really a heavy-duty unit. Your screen is much
    lighter, so you could use a lighter hinge
    I was talking to a friend last night, about the carpc and trying to figure
    out a better mount for the keyboard and he said try to put it on a hinge
    that made me remember what you had said, and I went out and got
    a hinge and a sheet of Lexan and made this

    Top

    Bottom

    Side



    I used a old grinder wheel on the Lexan and hinge, was going to replace
    that grinder wheel soon anyway, - soft metal and plastic can make a
    grinder wheel crack - I used the grinder wheel to round the edges,
    and sandpaper to smooth it, and a foam sanding block to finish it off

    Its still not perfect, I need to get some Velcro or something to keep
    the keyboard from sliding off, an do some small changes, like move the
    hinge and Lexan down some to give the LCD more freedom of
    movement, you can see what I mean here



    Just some longer bolts and washers should do

    I found some Velcro, washers, nuts and bolts and fixed it

    Got my DCL11 POL power supply in, and mounted in an old laptop
    hard drive caddy.

    Look how small the the DCL11 is.




    Later on I will mount it inside the same ATX power supply case
    as my M4-ATX, this will do until I have more time

    Good luck
    Keyboard space is at a premium in a car. The problem is that every keyboard that fits my fingers is too big, and everything that fits nicely in the car would require me to use a stylus. I'm wishing for a way to put a small QWERTY touchscreen in the steering wheel.

    Now, as to your project:

    You Could Buy a Laptop Mount
    I looked at the $80 laptop mount you linked. It looks pretty good.

    At first glance, the Amazon upgrade listed, the "Computer Car, Truck, RV Mount: laptop table stand, camera" looked even better for $20 more. But I realized there's no data on its weight capacity. The vendor's website provides more information, but still no capacity data. And I'm inherently suspicious of anyone who ships something that's relatively light and charges $19.95 shipping and handling; it seems devious -- I'd find them more credible if they charged realistic shipping and just kicked the price up higher.

    But Maybe You Could "Run What Ya Brung"
    You're pretty ingenious, so, instead of buying a solution, how about modifying the system you've built? You could reduce the size of the keyboard tray to only the depth you need, and attach the keyboard to it with Velcro. You already have it hinged, so you might be able to simply swing the keyboard down when you don't need it.

    I suspect that, if you'd add copper washers sandwiched between steel washers on each end of the hinge pin, you could tighten it to a point where it would provide enough friction to hold the keyboard and tray in any position you choose, but would still allow you to move it easily without fracturing the Lexan.

    Those few copper washers would cost lots less than the laptop mount.
    .

    Im guessing he means nasty, in a good way.... Now a days you dont know what someone means. Maybe you should build a piece to match the woofer box that the PC goes into, so it looks uniform. Other then that the install is nice, very clean.
