Carputer.

So! Now that I have your attention, I'd like to show you all my little upcoming project. I recently put in a double din Pioneer Avic U310BT, and wasn't too happy with the deck as a whole. Then the faceplate got stolen out of my car (guess they thought it was standalone gps). -___________-


My buddy was talking to me about the carputer thing for a while, and after thinking it through, I figure this is actually the best route for me. Easy to upgrade ($100 motherboard/cpu/gpu instead of 600-800 for some new fancy piece of PROPRIETARY hardware)


So here's what I bought.

http://www.mo-co-so.com/Dual-Core-1-...-cbs-zot-2.htm
Intel atom 330 (hyperthreaded single core) with nvidia ion cpu (nvidia 9400gt graphics card)
2 gb ram
built in: 5.1 surround, bluetooth, wireless n
http://www.mo-co-so.com/Sirf-III-USB...cs-gps-usb.htm
SirfIII Gps dongle (lololololololol dongle)
http://www.mo-co-so.com/Joycon-EX-St...mcs-joy-ex.htm
joycon steering wheel dealie. Now one thing to mention about this: If you own a pioneed deck and want a steering wheel interface to get that oem feel and featureset, it'll set you back 200+. This joycon not ONLY interfaces with the steering wheel, but also will do LITERALLY anything you want (multiple button setups, logical buttons and physical buttons. Press events and hold events. Make events do either keystrokes or open up programs)

All for 30 bucks. Retarded. I'm going to splice this with my dsc button which will play an mp3 that has the 'YEAAAAAAAAAAAAAAAAAAAAAAAAH' from csi miami. It'll get annoying quick, but will also be hilarious.

http://www.mo-co-so.com/Double-DIN-L...lil-701-dd.htm
And then the double din lilliput screen. I see a lot of people ripping them apart, fabbing them into the nav unit (which I will do EVENTUALLY), but this came with the double din casing, so I'm pretty happy with that for now. Very clean looking etc etc etc.

So all in all, I've spent about 750 taxes, shipping, and brokerage fees included and I've got double the functionality as a standard deck.


I'll be using centrafuse and dashcommand for the front end, just like the dude that put it in his rx8 with nav section from japan parts.


Some teaser pictures : D

BUT! I will take way more pictures once it's closer to an rx8. I didn't put this in the D.I.Y. because I didn't plan on walking through the whole process... buuuuut I found that there were a couple unanswered questions (Like how to use the line out of the carputer with the stock bose system - I tried searchin', I swears it)


As an aside, my buddy that was talking to me about the carputer, bought all the same stuff, minus the joycon, since his steering wheel doesn't have buttons. For the record, he runs an a6 with a bunch of mods hitting about 400whp over all 4 wheels.

ZOMG Alzorz, IT WAZ TOTALY U LOL!

But yeah, I'm going to need to have a good talk with you about this whole nav thing.

i used a grom aux in module for the line out to get sound from the pc to the bose system.

Unfortunately I'll be running without the stock stereo/headunit.


I'll just have the bose speakers and amp. I'm hoping I can get something to bump up/down my signal so it'll go directly into the amp.

Looks like a very good setup.

I couldn't use the joycon because it has issues with my intel motherboard, but it's a very nice piece of hw. I actually went with a phidget device for that since I can use it for other sensors later.

I'm also running dashcommand v2 and it gets a "wow" from the new passengers everytime I pull it out. Can't wait to have some free time and design my own dash. It's also good to quickly read the OBDII codes.

Good luck with the build.

So my buddy and I went halfsies on Centrafuse 3 (Apparently comes with two hardware licences). He claims it's running super slow on his system that has 7 on it, so I'm going to give it a shot on mine, just in case he's crazy/bad at computers

Beyond that, I've got the thing powering up from a rigged up power supply (same way you can rig one up to run an car speaker amplifier) The screen works amazingly, I finally found windows 7 drivers for the GPS dongle (lololollolooll) and centrafuse 2 works super duper well.

And peggle has never been so fun. Plants and zombies, too. So much fun. It's not going to go into my car until I've got all the software working without a hitch. My odbII bluetooth dongle (lolololx2) is in the mail from the sunny smiling beaches of china.

Excited, tbh.




p.s. SO! I forgot to mention, does anyone know of a way to get into the bose amp the same way as a normal deck does? My pioneer was okay (little bit of noise on the lines, but the point is I got sound to come out properly), and I want to interface with the stock bose system for the time being, before I get my subs/amp/speakers/etc.

anyone have suggestions and tips or a harness diagram/explaination on the difference between the output of a aftermarket deck and the output of a computer sound card?

Well snap. Thanks Ximo, when I plan on keeping it oem lookin' I WILL need that. For the time being I've got a metra double din kit that I was using for my previous (stolen) stereo.

No progress yet beyond having my car overheat like no one's business. Buying a thermostat today, hopefully it'll be in by the weekend. And then I'll be able to start fiddling with stuffs.


So in keeping the bose system, who thinks that the outputs from the soundcard will be sufficient for the amp to amplify? I'm just going to tap into the lines and see how it sounds.

edit: one more update. Format the 7 box, and ran centrafuse on xp. No difference in speed, imo. Menus are still 'slow' (there's a slight delay when you press the buttons).

Haven't screwed around with the joycon yet. Does anyone know if the buttons for the steering wheel are different circuits, or just different resistances? Is there any information anywhere for that?

The outputs from sound cards are usually sufficient for the amp. The signal/noise ratio might not be absolutely fantastic, but good enough for most people.

The buttons on the steering wheel are all in the same circuit in a resistor-matrix style, so the joycon will work perfectly with them.

So I made a little update with peeshurez! : D

Basically I've put the carputer where the tire repair kit was before it was stolen. Once it's all in place and working, I'll be sleeving the power/audio lines so that it's a lot more oem looking.

I've got the video/power cable for the monitor ran through the center console pillar stuffs, and tucked in under the seat area (caution: those metal areas are friggin sharp!)

So I've got the obdII bluetooth dongle (lolollollololo) hooked up, but it doesn't look like it's sending out a signal via the bluetooth. I need to check with another computer, because the bluesolei software is.... weird, to say the least.

GPS works awesomely, screen fitment is a bit of an issue. When I put the metra kit over top of it, the metra kit presses on the top of the screen a little, and makes the mouse pointer jump around a bit.

Fuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu

So I finished up connecting all the stuffs. Ran the power lines for mycomputer. Ran the remote off the cigarette lighter. All was well.


And then I put the metra kit back on. I'm getting a couple lights on the air con buttons and the screen works fine. However, the temp **** does nothing and the buttons do no respond.


HOWEVER, the middle one does it's thing when I hold it (Abmient temp. Abmient temp C. Clock adjust. Text change), but the buttons won't turn on a/c or change where the air blows. I'm beyond sad.


Can anyone please help? ):

update update update

I tried soldering the inside up as per a thread that the metra tech guy suggested, and it seemed to work. I think it was just the fact that I was refastening the connectors.

Then I put the rest of the stuff together, and while the buttons worked (I could turn a/c off and change all that stuff) the buttons would not light up and it wouldn't show the changes on the dash. Looks like I pulled something out or kinked something while putting it all back together. Meh. Gonna have to take it apart one or more times.

When I DO take it apart, I'll be grabbing the joycon and connecting it to the harness where the media buttons are. I'll also be running a usb hub to the front of the car.


Are there any +5v lines in the centre console of the car that I can power the usb with?

Also, I decided to forgo the bose amp/speakers, and just buy a new amp and speakers for the car. Got a nice deal at my work for a 600 watt pioneer 4 channel. I'll probably run the subs off that, too. We'll see how fancy I want this to be. Currently I've just bought the amp and haven't bought anything else. I'll just run the sound to the rear deck for now, while I'm looking for suitable front component speakers.

Another update:

This is more for me than anything, but if anyone's subscribed or interested in what's on the horizon.

I've got my Bluetooth obdII working, but it doesn't reconnect when the computer goes into hibernation mode. This is an issue. I'd rather not have to disconnect and reconnect the bluetooth device. Now, I may be able to program a script to disconnect and reconnect the bluetooth device, but I'm hoping there's an easier way.

To do list:
Fix HVAC connections
Connect joycon to steering wheel and dsc buttons. Set them ***** up.
Run USB to front of the car so I can plug things in. Figure out ideal location for usb ports.
Run amp wire. Buy door speakers. Run the wires and have audio back in my car
Reinstall windows 7 but use the 32 bit version instead. -_________-
Run GPS to where the gps module goes in the rear deck (anyone have info on how to run that?)
Run high gain wireless antenna to the same spot. Figure out how to orient it for best signal.

Pics when it's not raining. I'll use a proper camera, too.

So upon trying to fix the hvac connections, I fixed them. And then ******* broke them more than they were beforehand. I got the screen displaying and the led's properly lighting up, and then somewhere between putting the dash kit back in and looking up, red digital screen went dead. No power is going to it I don't think, BUT you can faintly see characters on the screen, just the red isn't there. However, that's happening ever when the car is powered off with no keys in... and the metra box unplugged. Please tell me I didn't fry the screen.

: C

I just bought some energy 6.5 inch components for the front doors. Rear deck is up and ready to go and the amp is all hooked up and whatnot. So sound is a go.


To do list:
Fix HVAC connections Refix hvac and hvac screen
Connect joycon to steering wheel and dsc buttons. Set them ***** up.
Run USB to front of the car so I can plug things in. Figure out ideal location for usb ports.
Run amp wire. Buy door speakers. Run the wires and have audio back in my car
Reinstall windows 7 but use the 32 bit version instead. -_________-
Done. Just need to run fron speakers.
Run GPS to where the gps module goes in the rear deck (anyone have info on how to run that?)
Run high gain wireless antenna to the same spot. Figure out how to orient it for best signal.

So I need some help from you peoples. I'll probably make a wtb thread, too.


The screen/hvac led's and whatnot have been effing up because of a small wiring harness I pooched. I pulled on the wires too much, and pulled one of the wires out. SOOOOOOOOOO I need to replace that harness.



So if you look at this picture, there are two harnesses that come out of the unit. At this angle, the one on the left controls temp and the one on the right controls the data going into the metra kit to the display. I have messed up that harness that's on the right. Anyone have a spare one sitting around? I went to the mazda dealership and the guy ACTUALLY suggested buying the ENTIRE wiring harness package for the ENTIRE CAR for 2 grand, or just the front (because I need the dash, front lights and engine harnesses........... ) for a grand. What is wrong with these people? He actually presented it as a solution. I had to remind him that I need a 3 inch long bit of wires.



worst case, I'll try and repin out the thing. I just did a horrible job the first time. It's a REALLY difficult pin to put back in.

Help help help help help!

i would definitely try to just put it back or go to the hardware store and find a terminal that is a close enough fit. either that, you're looking at a trip to the j yard

Wooooo

Alright, I tried my stock stereo on it, and the screen worked flawlessly and the hvac buttons worked as well... so, I screwed around with the pinout and harness and spent the better part of the evening on it.

Phew. Got it working.

I think I'm going to just run the usb to the glovebox and do it simply, instead of fancy inside the rear cubby of the arm rest.


2 reasons:

1) There's simply more room. My other car had the usb/ipod connection running to the glovebox and it was perfectly fine albeit not as impressive looking

2) At this point, I just don't want to break anything anymore. Cutting into the arm rest = can't go back = gonna make a mistake. If I decide to go that route, I'll spend the 50+ bucks to get it done for me.


To do list:
Run GPS to where the gps module goes in the rear deck (anyone have info on how to run that?)
Run high gain wireless antenna to the same spot. Figure out how to orient it for best signal.
Connect joycon to steering wheel and dsc buttons. Set them ***** up.
Run USB to front of the car so I can plug things in. Figure out ideal location for usb ports.
Fix HVAC connections Refix hvac and hvac screen
Run amp wire. Buy door speakers. Run the wires and have audio back in my car
Reinstall windows 7 but use the 32 bit version instead. -_________-
Done.
Just need to run front speakers. Speakers are ran, now I just need to figure out how to force matrix surround on the speakers (Make all 4 speakers push the same sound at the same level.

RESSURECTING A THREAD FROM THE DEAD! : D


So, I just ordered the RII Mini keyboard from http://www.tomtop.com/24g-wireless-m...9b_p10332.html It's 49.99 and actually really fantastic.

If you search for coupons, there's one for 10% off the whole invoice, or 20% off the keyboard.
So if you buy other stuff, you might want to consider the 10% off invoice option, or 20% off if you just buy the keyboard.

It's a keyboard with a laptop mouse pad built into it! Rechargable lition ion battery (usb chargable).

It's also got a laser pointer built in. Handy in road rage situations! I also bought an antenna extender cable, so that I can extend the wireless antenna to the rear deck. I just need to figure out how to get the rear deck apart.

USB is ready to go to the front, and when I do that I'll also run the steering wheel controls. WOOOOOOOOOOOOOOOOOOO
