    Hey everyone,

    Project Story (feel free to skip this part :p ):

    It all started with the v1 which was nothing else than a Infill G4 PC (double din) that I installed in Dash using a schoshe kit. Install pictures can be found on this page: http://www.tacomaworld.com/forum/audio-video/2600-car-computer-my-2007-tacoma.html

    I was not entirely satisfied with a few things about the computer though: lack of power, no upgrades, some annoying hardware/driver bugs, the not so great quality of the touchscreen ... just to name a few.

    I did like the fact it fits a Double Din enclosure very much, and being able to access email/web from my car (using my Blackberry modem) in addition to all of the other things a standard radio/nav system can do really convinced me to keep using a car PC.

    About a year ago, I really started looking for a standard Double Din enclosure that would be able to host a Mini-ITX motherboard which can feature decent and low power CPUs (read new generation Intel Atoms!). I didn't find a single case for the simple reason it is just too tight.

    Then I realized that our 2nd gen. tacomas have this nice curved front panel with about 1" of free space between the bezel and the front end of a Double DIN A/V unit. This 1" was all I needed to fit a mini-ITX motherboard.

    That's what got me into designing and prototyping a custom double din mini-ITX enclosure.

    Components:
    Motherboard: Zotac NM10AE that features a Dual Core Intel Atom D510 CPU: http://www.zotacusa.com/zotac-nm10-...ual-core-mini-itx-wifi-intel-motherboard.html
    Memory: 2GB DDR2
    Hard Drive: SSD Intel 30GB
    PSU: M3-ATX
    Touchscreen: LILLIPUT 8" 869GLT HDMI
    Networking: Wifi built-in the Zotac motherboard
    Networking: Ethernet connection to a Netgear Access point (installed in the glove box)
    Networking: tethering over Blackberry for 3G internet access (connection is shared to the access point so that people in the truck can have access to the internet using wifi)
    Audio: Built-in 5.1, only using 4.0 though.
    Audio: 4x 40W amp - final design is likely to use an enclosure-less amp to save some space and gain some W
    Software: Windows XP SP2
    Software: Blackberry Desktop software
    Software: Centrafuse 3.5
    Navigation: USB Globalsat BU-353

    Project details and pictures:
    This is my original Infill G4 (that I've sold recently)

    Here is the case that I've designed (the front panel isn't attached)

    Fit check again, different view

    Inside the case... (sorry that one is blurry)

    Amp attached to the inside of the top panel (cheap amp for the purpose of testing the all project)
    [​IMG]

    Metra kit that will be used without the additional provided frames. and painted silver to match the Vent panel below
    [​IMG]

    closed unit with the original black anodize front bezel (I've had it remachined and refinished because I was not satisfied with the anodize quality, now I sand blasted it before anodizing it's much better, pics later)
    [​IMG]

    mock-up with the Metra kit (before paint!) and the unit (with original finish)
    [​IMG]

    and that is the unit with the 8" touchscreen attached to the unit using a articulated arm for custom positioning.

    sorry for the pics quality, it's all Cell Phone pictures and I haven't taken the time to take pictures. But this project has been going for a few months now and as I get close to being finished I figured I'd start preparing this "worklog". I will try and keep it updated.

    Don't hesitate to ask any question! I will be adding more pictures and finishing this in the next couple weeks hopefully!

    cheers!

    Very cool!

    Did you CAD out and CNC the aluminum case yourself? Looks great man.

    One question about the amp. Why not use a chip amp kit or one of the Sure amplifier boards from PartsExpress? A naked board would be way easier to fit in the case and would probably cool better too. Do you anticipate any cooling issues with that amp mounted with its heatsinks upside down?

    Yes. Measuring the curves and actual space available in the taco was not the easiest thing to do. but it turned out working pretty well without any major problem.

    I have a couple fans installed to pulled the air out of the case and plan on adding a slim 92mm fan on top for the amp.

    This is also the original revision just a proto, I have made several modification in my CAD and will CNC maybe another couple units for a taco friends.

    I honestly didn't spend any time looking for an amp but I know for sure I can fit a better one in the same space and I will either need to find one without enclosure or take it out myself!

    hmm you're making me regret I didn't look into this earlier :D I am going to look into and order one to update my CAD for the final design. it will fit pretty nicely and I will save some space to even fit a large and quiet fan inside the enclosure.

    I've installed Windows 7, drivers, centrafuse, BDS over the week end. Power consumption is under 20W for the computer/display under centrafuse 3.5.
    I've also ordered this 4x100W amp, I'd like to see how much space I could save before I start finishing the wiring.

    F'ing knight rider that shit lol!

    Just curious but why did you not try and integrate the screen into the dash? I've seen an iPad in there and looks like your screen would fit as well.

    the motherboard is too long and I couldn't extend the unit at the back either because of the limited space. I could have installed the monitor directly on the front (protruding) but I liked that it can be moved around for easier use when stopped.

    you do need to use a relay for in car use though, right?
    What type of relay would you use?

    My display doesn't have an ignition wire either so it's probably wise to get a relay for that too.

    Yeah I don't think they have an auto sensing power lead so you'd need a relay.

    I received my USB ODB-II scantool today, I'll try to hook this up with the rest of the computer over the week end!
    Does anyone where the ODB-II harness is located in a tacoma? I don't remember seeing around the stereo area. :confused:

    Kudos to another carPC! I like that you managed to shoehorn it into the dash.

    Currently, I use RideRunner as my frontend...mainly because it's free. Ultimately, I ended up buying DashCommand and integrating it into RR so that I could get some good OBDII software. Does Centrafuse have native OBDII support or do you need to buy it separately and then integrate it like the GPS software?

    It sure is fun to watch the data on your vehicle in realtime! :D
