A couple more finished views showing the I/O panel (back), extensive use of split loom, and the modular "hood" type chassis design.
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'
Got the computer in the mail today, a day later than I thought, but no matter. I will update you later on.
