    2006 Chevy Colorado Work Truck finished for now

    I am not a patient person, so there is not much desirable fab work here. But I thought I would share anyway. Maybe it will give someone some ideas, like I got when looking through the forums when doing this project. Here are the innards of my PC:


    In the microATX case is:
    GIGABYTE GA-M61PM-S2 motherboard
    AMD 45W 2.3 GHz dual core CPU (AMD Athlon X2 BE-2400)
    2 Gb RAM
    DASTX DC-DC converter mounted in old ATX power supply case
    320 Gb IDE Hard Drive
    500 Gb SATA Hard Drive
    Windows XP Home
    Homemade remote control relay circuit board
    Homemade delay circuit board
    Mean Well SD-25A-12 DC-DC converter
    2 USB header adapters
    The PC is turned on or off with a key phob:


    Left button ON; right button OFF. It is part of a Ming RF transmitter receiver set. It activates homemade decoder, relay driver, and delay circuits that turn everything on. The delay circuit holds off the remote for my audio amplifiers for 30 seconds, because it takes the PC 40 seconds to boot up. All this lets me turn on the PC while walking up to the truck to make up some of that long boot time. This also lets me use the PC with the ignition off.

    The PC is installed in the space behind the amp board and between the woofer boxes:



    I installed the Lilliput 10.4Ē monitor with a standard dash kit by taking apart the mount that came with the monitor and bolting it to a board bolted to the kit. A piece of foam yoga mat is wedged behind the monitor to keep it from shaking or bouncing when using the touch screen. You canít see it or the mounting hardware behind the monitor without major contortion.



    It kind of blocks the AC controls and vents a little, but I like the big monitor. The radio bypass box that you have to put into GMs when you take the radio out is behind the dash kit. Without it you lose the warning chimes for headlights, doors, etc.

    I have my controls and indicators under the shifter:


    It has the power, overload, and thermal indicators for both amps, the bass gain knob, the bass amp voltage, a Kicker parametric EQ, and a USB port from mp3car.com. I control the main volume with the EQ. I plug in a USB laptop mouse, USB rollup keyboard, USB DVD drive, or USB flash drive into the USB port here when needed. I have a couple other USB extenders under the seat if I get in a jam. I donít use any hubs unless you count the active USB extender I had to use to get the touch screen to work right.

    This is the underside that shows the USB DAC:


    Itís hard to tell, but I also make my own RCAs now using silver plated aerospace wire and aerospace sleeving. I donít know if it makes a difference, but at least I am trying.

    Under the control box, I have a USB OBD scan tool and a relay that controls the OBD power line housed in an old ground loop isolator case. The scan tool is always plugged into the carís OBD port.


    I gained access to the OBD power line in the serial cable by making an extension cable from two RJ45 to DB9 connectors. I use a regular ethernet cable between them with the OBD power wired separately between the pin 9s. The OBD power on the pin 9s is only connected by the relay when the key phob has been activated so my battery doesnít suffer from long periods without the truck turned on. This cable also gives extra length so I can connect to someone elseís car without removing the whole setup.

    The stereo consists of:
    2 Phoenix Gold ZX450 amps
    2 12Ē JL Audio
    4 6.5Ē Infinity Kappas in the doors that just sound OK, not great
    eDead sound deadening in the doors and floorboard that doesnít stink anymore, thank God.
    Updated power and ground with 2/3 of the Big Three and added circuit breakers and fuses:


    Here is my old setup which I removed because it was too ugly and complicated. It had two USB data acquisition devices by NI and ran LabView to monitor amp input current, output voltage, fan speed, and internal temperature. It had all the shunts, signal conditioning, and isolation transformers needed for that. It also ran an extra monitor off a USB video card. Not to mention all the extra audio stuff. I never used the data though so I took it all out and simplified everything.

    I got the remote and receiver from http://www.rentron.com/PicBasic/RemoteControl.htm It looks like the one I got is no longer produced, and they have replaced it with a long range model by Linx. The new one is a little pricier and a little bulkier but it has 4 channels and you can turn the PC or any other relay controled device on from 1000 ft away. That site also has schematics for everything to help you build your own. That's what I did, because I wanted to specify my own relays, and assemble myself. That saved on cost too.

    Dog-gone-it! I was hoping for something a lil simpler than that. Even though its way out of my league, I'm sure I can find some help on this. Thanks for the link babyface06.
