  • GMC Complete Bolt In Dash - CPU/HD/PS/RADIO/CD/FB/AMP

    So this project was a team effort between Stone Statue (Scott) and myself to create the ultimate bolt in solution. Scott obtained all the hardware and hired me to design / build a chassis and mounting system for his GMC savanna. Also in the plans was to build an AMP9 kit to be used as an internal amp. I think you'll agree this is one beast of a bolt in carPC considering it holds so much hardware and is contained into a 8" x 7" x 5.5" case. Of course all components are shielded from one another, properly grounded, and remain easy to access for service. Most of the wiring is custom made, including fully shielded 100% copper audio cabling, and usb header cabling, and soldered power wiring. The amp Tripath has been bonded to the chassis making use of the aluminum thermal properties for heat dissipation.

    Here is a list of the hardware:

    LCD - Lilliput EBY701
    MAIN BOARD - Intel D945GCLF2
    RAM - 1 Gb 667Mghz
    DISK - 64Gb pqi SSD
    RADIO - HQCT
    AUDIO I/O - MitchJS USB Audio Selector
    DATA I/O - Fusion Brain v4
    POWER - M4-ATX
    OPTICAL - Mp3car Slim Line Slot Load
    AMP - Amp 9 Kit 50 Watt x4

    Everything from the build has run in harmony on the test bench and I have been impressed with stone statues project vision from the start. Hopefully The install will be equally as successful. I shipped the PC out this morning so he should have it in a few days. I'm sure he'll chime in here with some feedback on the install aspect of the carPC venture. Scott can also tell you more about the software and what his is doing with the fusion brain to control the HVAC of the van.

    Until then here are some pics I snapped along the way. Questions & Comments welcome

          Looking good! I eagerly wait this in the mail (probably Wednesday). It bears mentioning that there will be black ABS filler in the space between the monitor housing and the optical drive. I'll be sure to take pictures once I get it installed.

            how did you tackle cooling? or is that not a concern? i didnt know something 8in deep would fit inside the dash. i will say excellent planning guys

              The depth is 7", width is 8". The width is a non standard measurement, but there is nothing standardized about late 90's GM design. Cooling is not a concern because aside from the amp none of the components really generate much heat. The Power supply is only like 25% loaded so it runs cool. The Intel ITX runs cool, no standard hard disk to heat things up. The amp will be generating the most heat but it is bonded to the chassis. The chassis is made from quite a bit of .063" aluminum stock and is actually more of a thermal mass than most people realize. There's probably 5 Lbs of aluminum in the chassis.

              When I ran it for an hour on the test bench adding the drivers for the fusion brain, HQCT and USB audio selector, it was still cool to the touch.

              Here is a close up of the amp. It arrived in a bag of parts and I soldered it together. One change I did make was laying the big caps down on their side to make the amp more slim in order to fit.

                ok because i think my dash is 7 deep and im gathering inspiration from your build to redo mine. have you guys taken into account the length of the audio cable ends themselves? i know they dont seem that long but they are a good 1/2in which could cause problems with limited space. only reason why i ask is for ideas for my build.

                what did you use to bend the aluminum and why that choice in material?

                  It is actually the best choice possible in my opinion, considering the cost of silver or gold.

                  edit: And the tooling I use is a 4' drop shear, and 8' break. Sometimes I use a small 12" fingered break on the smaller parts, but for the .063" aluminum I use the 8'

                      Awesome! Hope everything arrived in good shape, I packed it well.

                      You can find the PCI card and the schoche brackets in the padded envelpoes.

                        Yes everything came back in good shape. I tested the HQCT and while it works, I'm less than impressed with its quality. Per the conversation we had, I'm going to upgrade to the BoomzBox as soon as possible. I will keep you posted.

                            I have been off for spring break so I've had extra time to do stuff to the van, which I have taken advantage of. I've changed the oil, rotated the tires, and prettied up some wiring. I also installed a six circuit fuse panel near the battery to run the power for the vanputer. I'm going to drill a hole through the firewall then grommet that hole. It's going to be 10 gauge wire (red positive and black negative) fused at 20 amps. Pictures soon.

                            PS: I also got an extra third rear brake light out of a junkyard today and I'm going to see about installing the rear view camera there. If I mess up, I'm only out $10. I want to install the rear view camera such a way that it's "reversible" if I decide to sell the van. This way, if I decide for whatever reason I no longer want a rear view camera or want to relocate it, all I have to do is replace the third brake light with another one, that way I don't have a gaping hole in the body.

                              Update: I have replaced the HQCT radio module because I was less than impressed with the reception quality. I got this instead:

                              http://cgi.ebay.com/ws/eBayISAPI.dll...=STRK:MEWNX:IT

                              And am using this to interface it:
                              http://www.rush2112.net/mkportal/mod...products_id=39

                              I just got both in the mail today so I only hooked it up briefly in the van, but from what I could tell, the reception is MUCH better than the HQCT, so it's at least a step in the right direction.

                              More to come, including pics.
