Brian's 2004 Altima 3.5
I'm getting started with my First Carputer and it's going to be a fairly complete system.
I'm going to be breaking up implementation of the system into two "phases":
Phase 1 will be the main carputer, power, amps, speakers, gps, the touchscreen, and bluetooth. This will get me up and running for a few months of software testing, etc.
Phase 2 (when I'm ready and well-read) will be adding Engine Diagnostics and any other upgrades I come up with.
I don't have any before pics of the car but I will take some soon and post them.
I hope my progress will be well updated, and interesting, and will spark the interest of some of the veterans out there. I will be asking plenty of questions as I will be learning a lot along the way.
Here is a diagram I made real quick to help get started on my purchases.
I already own most of the audio gear, the battery, audio wiring, and the fuse & distro blocks.
What I need to buy are the carputer components, touchscreen, and carputer wiring
My First questions follow:
1. The JetWay J9F2-KHDE-PB 479 Intel 945GM HDMI Mini ITX Intel Motherboard looks to only have SATA (no IDE). I have yet to find a slot load DVD drive that is SATA so can I succesfully use an IDE-SATA converter to get the dvd drive working with the motherboard? The few reviews I have found on IDE-SATA say it works great with HDs but can be sketchy with DVD drives.
2. Am I going to have problems running the VGA, DVD data, and both their power lines the length of the car?
3.Should I fuse the power coming out of the distro blocks? (ie. fuse the amp lines and carputer line in addition to the 130A fuse in the engine bay)
4.Living in Santa Cruz, CA, will the trunk be too warm for the computer? I'd rather have it in the trunk for security reasons (I can really bolt it down there).
5. I have access to a Capacitor for the Subwoofer but have heard mixed opinions on their usefulness. Would it be worth hooking up or would it add unneeded EM interference for the carputer?
Thanks for any insight into these questions, more will be coming (along with some pics of my car)
Well... its been a month and I am happy to report that this is my first post from my carputer. Now, don't get too excited... its merely sitting on my desk hooked up to my monitor and keyboard, but at least its hooked up and I can get rolling on software setup.
For those of you who missed, here are the specs of the carputer:
-Jetway J9F2 Mini ITX Board
-1.80 GHZ Core Duo
-2 GB RAM(had to run a 533Hz for board to be stable, others have had this problem)
-300 GB 3.5" HD (will see how this runs, I can always upgrade to more rugged portable)
-MSI Star Key long range bluetooth dongle
-Holux GPSlim236 (GPS)
-Linksys Wireless N USB adapter
-M2ATX car power supply (hooked up to gutted desktop supply atm)
Thats it for now. Starting to get drivers and whatnot installed and then the real fun will begin. I am going to ghost image at a few key points along the way to save me time later if there are snafoos (or if HD breaks from bumps down the road (pun?) )
I should also mention that I got my front speakers and they are CDT HD52 component speakers. Sorta been my dream set for a while and I scored a great deal on ebay.
Current dilema is alternator. I will definitely be able to user the power but from a decent amount of searching and emailing the best price I can find for a HO alternator for 04 Altmia is $700 ouch. I will prob get all hooked up first.
1.Just use a usb slim dvd housing,and you can run the cable back to the trunk,and if the housing requires 5v power,you can use a molex off your power supply.

3.I would just fuse the power supply wire for the computer,and the rest is fine how you have it....the amps have their own fuses.
4.Depends on the case you'll be using,and it's cooling capability.
5.It can't hurt,and will probably give you a little headroom on the sub amp.
Thanks for the answers seanshine:
1. Yeah, It turns out I do have IDE, and I ended up getting a slimeline-usb converter so I'm good.
5. I will definitely use the cap until I can afford the new alternator. My car is going to need all the power I can get.
