    My 2002 Nissan SE-R Spec V Carputer

    It's late, so I'm mostly just reposting from my thread on B15sentra.net. I've been working on this for a while, there's still more I want to do with the car and carputer (like a back-up camera, wi-fi, etc. Always looking for ideas and suggestions). I've seen a few projects on this site and used them for inspiration and ideas, so thanks to those folks. If you have questions, suggestions or opnions please share.

    -outside shot. the rain finally stopped, so I washed her up real nice like.


    -front grill shot...if you could only see all of the road rash. Oh it hurts!


    -Wide shot of the interior dash


    -shot of the screen. I'm running microsoft streets and trip, it's not bad but there's a list of features I wish it had. I'm going to try iguidence after reading some of the posts here.


    -Side view of monitor. I want to get some sort of shroud to cover the sides, but the gap is so small it would get pinched when closing. Any ideas or suggestions?


    -Stock looking while parked. You can also see the mic, right next to the temp gage.


    -extra usb port (blurry picture not your eyes)


    -Keyboard in the glove box


    -New din panel. Dvd-Rom eject (flush when closed), toggle on the right is for aux input on/off. Button and led on the left is for laptop.


    -Old din panel

    The Carputer has been my biggest project on the car, since I had some of the major components and figured it would be cheaper than getting some of the other performance mods I want. I knew I could take advantage of it on a daily basis. My major guidlines for all mods are: I must be able to return the car to stock at anypoint (so no cutting, drilling or damaging stock parts) and I want to be able to do it myself or with the help with a friend.

    I started with a compaq PIII 1Ghz laptop that I already had and then got a touch screen, and other compenents. My goal was to run the audio from the laptop through the stock HU. My first setup was used 4 toggle switches that interrupted audio from the HU to the amp with audio from the laptop to the amp. This worked but wasn't my favorite since I had to control the levels from the laptop and had to toggle four switches to change inputs. I eventually found the CD changer pinout and made an aux. input from it that is controlled by a single toggle switch on a panel in the spare din. On the panel I also put a DVD-Rom, on/off for the laptop and indicator led.

    The laptop was originally going to be under the passenger seat, but I then decided to relocate it to the trunk. The touch screen tucks away for a stock look when parked to avoid extra attention. Finally I put a flexiable keyboard in the glove box and a usb port in place of the second 12V outlet by the e-brake. Part of the setup includes the ability to switch the aux input from the laptop to any audio device with a 1/8" mini socket (like an Ipod). I have a gps reciever and I'm also running voice recognition software. I haven't had much luck with microphones and the road noise ratio, but when parked it works great! I'm going to try a bluetooth mic (those cellphone ones) see if that works better. I just bought a wireless nic and since SF is getting free Wi-fi throughout, maybe I can stay connected while driving. I'm using winamp with my own "touch-screen" skin for audio and video controls.

    Next step is to add a webcam to use either for security (get the license number of the bastards that ding your car when you're not around) or just as a back-up cam.

    Well I think that's about it. I can do a write up on the monitor mount if anyone would find it useful.

    What about some type of cloth material (something that does not wrincle as bad), it would not look perfect, but it would eliminate the gap.

    Your setup looks good though. I like the setups that get tucked away when not in use.

    Matrix 24: I thought about a cloth solution...I think that's probably the only way to go, I just need to find something that pulls in behind the screen (stretchy material?). Otherwise if you look at the pic where it's closed, it would get pinched between the lid and the outside wall, with part of it sticking out. I don't want to have to tuck it in manually each time.

    Husalah5150: Here's the DVD-rom I ended up getting: http://www.targus.com/us/product_det...?sku=PACMB010U. It's a Targus USB 2.0 slim drive, I found it for $127, which is still a bit pricey. The reason I got it is that it uses one USB port for data and another for power (you can still use that second port for a keyboard or mouse, so you don't lose a port). It saved me on haveing a sepearate power adapter or tapping into another power source from the car.

    On the escalade install I did we were going to use fabric and some elastic. If you make the elastic draw to the center it will not get pinched. We can talk more through PM if want some more info.

    kudos on the stealth install, i am planning on undertaking something similar myself. i'm curious to know what else you did to get the factory head unit to "see" the audio coming from the computer through the CD changer harness. I have a copy of the FSM but i'm sure it's not as simple as tapping the left and right audio channels that lead to the HU? any details would be greatly appreciated.

    So you might be in a diiferent situation since you have a 2005. Although it might not be the cleanest looking solution, I think your HU has an aux 1/8 in the front (right?). You definetly have a different Changer connection at the back of the 05 HU.

    On the 02 HU I used the harness pinout to identify the L/R + - cable and the power cable. I spliced the audio cables to plug into the stereo out of the laptop and the power to a 12v source in the car. I think the setup would benifit from having something like a pre-amp or some converter between the laptop and the HU unit to balance out the signal and put it into a better range for the HU.

    I don't know enough about audio to know what that unit is and haven't done anything yet. Still searching. But the audio levels are fine, the quality is exceptable to my ears (depending on the mp3 or movie audio quality, ofcourse). The only thing that I've noticed and wish I could fix (this may just be an issue with the sound card in my laptop) is that most of the bass is played by my speakers rather than my sub. I'm guessing this is an issue with the laptop sound card since CD playing from the HU have plenty of hit on the sub. It could also be the fact that the stock amp doesn't have a dedicated subwoofer ouput, but rather splits off from the two rear channels. Since the CD changer input is only stereo (as is the ouput from the laptop) the HU, which spits out 4 channels might not put as much to the rear 2 channels as the front ones.

    Anyways, there's more about the actual audio connection and setup here:

    molten silver must be a popular color. Serena [read: my car] also wears a silver dress.
    thanks for the info daspiderboris i believe that a similar setup with the relay may work in my vehicle as well. you mentioned that you weren't too keen on the low frequencies of your setup, have you considered ditching that puny sub on the back deck and running the speaker level signals to an aftermarket amp and sub? this will most likely be my next step after i get the computer together (of course in a fiberglass enclosure that i plan on building )
    utley3specv, correct me if i'm wrong but didn't i see you posting over on the vboard in the audio section as well? I like your screen install although i have opted to go for the stealth setup over the fixed display [damn thieves and vandals are everywhere!] what are the specs on your system?
    sorry for the novela; so much do say, so little time...

    definetely a clean job on the screen (great job on the reflection of yourself taking the pic ). I like that it's set in a little, should help with glare when the sun is straight up. I've been thinking about adding a little something for that as well.

    But I must also agree that I defeinetly didn't want it up all the time, especially when parked. Less attention the car draws to itself, less likely someone will break into it. I never keep anything out on the seats or in clear view (except the car itself).

    I think Silver is the "safe" color. It looks good, doesn't look dirty as fast as black or white might and scratches/swirl marks aren't as visible. When I picked mine up, the dealer only had this one on the lot. At first glance I actually thought it was a little too much, the seats the wheels and I still hate the back of the car like nothing else. But the price for the "features" and power was better than any honda or toyota I could afford and it's my first manual transmission. When I rode in it, I fell in love. I drove it right after a carolla, just comparing the exhaust note of the two around 4-5rpms, I knew I wasn't getting a carolla

    Back to the audio...I actually think the stock rockford fostage package I have sounds pretty good. It's got enough kick for my tastes, plus I'm pretty picky on what I spend my money on. I think before I do audio, I'd want to get some of the performance mods onto the car. I also want to finish the carputer, get a reverse camera and maybe an infared forward one. I also need to finish Bluetooth enabling my phone and voice recognition.
