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
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
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
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.
