  • Successful VGA to head unit yet?

    Sorry, been away trying to get ready for next db drags, still on the carputer seen with my xenarc and laptop (represent) but unfortunately I an told somewhere between 150 and 160db my laptop will quit, and I may have to add a head unit for comps .

    Not really using my touchscreen like I thought I would either, so I'm wondering...

    Has anyone been successful yet at using a (quality) head unit with screen as their vga input?

    I know someone was trying to crack Clarion, and I thought a certain Pioneer might?

    Thanks, I apoligize for not reading and following you guys as much as I used to, but I am out there in comp scene passing the word about us (MP3CAR.com) .

    Read the forums, then.
    Someone hacked a Kenwood unit, I believe.

    And who told you that your computer would fail at a certain decible level? Why would it?
    Have you looked in the FAQ yet?
    How about the Wiki?



    Under normal circumstances, a signature would go here.

      No one had to tell me, I've seen it happen. 150 - 160db and it will shutdown or freeze. Mine is doing weird things and optical mouse will not function at full volume and as of right now I am making the jump to about 7500 watts to 2 subs if you are wondering what it takes to freeze yours.

      Enough db and your body will fail too.

        Probably because the hard drive can't take it.

          that doesnt make sense......your laptop isnt producing the decibles.........i could see if maybe you had it right against a huge *** sub's magnet......but even then....

            Comp is maybe louder than you think, if you sat in my truck, you might understand what happens inside a computer, and everything inside the vehicle.

              .....unless you bought a laptop with a built in amp.....your computer is not generating that much sound.....the amp is doing it. Thus cranking the volume on the computer.....will not make it freeze/crash

                either you can use a top brand head unit with a hacked display

                or

                you can go about solving why your laptop is crashing.

                if you want to do the second one, I would suggest checking another laptop in the car. failing that, there are a zillion things that can be done to stop if from shaking, or being affected by shaking. For example, you could boot off a compact flash card in a read-only operating system mode. that would mean your system cannot crash from vibrations unless a you get hit by a stray astroid!

                lots of things to try

                  Never said my laptop has crashed, but it will as I get louder, right now it has failed to respond (pause) a few times (remote) and I have had to get in and turn it down (painful). In reference, people in my class are blowing their windows out and external podiums for signal units are common, but I don't want one yet.

                  From what I understand:

                  High end changer < head unit < laptop in terms of db tolerance.

                  And yes, finally to get back on topic, a hacked high end head unit is EXACTLY what I need (hence thread title).

                  Any ideas?

                      It's not cranking the volume on the laptop that's doing it....it's the physical db's (the force) that's messing with the laptop's hardware and causing it to crash.....

                        Exactly...

                        Don't want to have to take laptop out, or leave it in.
                        Only want one screen.
                        Looks like head unit and changer are inevitable, can shut down laptop or remove for comps.

                        Did a little searching and really didn't find anything but threads like this one where reply were same (search) .

                        Found the kenwood thing, $450 to mod + $1000 for unit, hmm. Wish it had been an iva d900 .

                        Podiums are legal in my class, just really don't want one.
                        Some kind of deadened lead container for laptop?

                          you could remove the harddrive from the laptop and make it boot from a compact flash card (you'll need an IDE to CF adaptor). A 2GB card should be more than enough to boot into windows + host a couple of CD's.

                          And for the times you need the laptop in there for mp3's, then just use an external USB enclosure, to use the harddisk which you now have out of the laptop. (or you can swap again)

                          you should be able to get encolusre fairly cheap, and the same for the CF-IDE adaptor.

                          the bass can do what it likes if there are no moving parts in the laptop (apart from the fans which I can't imagine would be affected by any amoung of bass, since their movement is centrifugal, not to mention that they don't always go on).

                          now that I'm thinking about it, there may be leads in the laptop that connect one circuit to another. with all the bass shaking, they could be getting disconnected/connected for miniscule times. This could induce a crash. A way to minise that would be to place the laptop on some cushioning, like some semi hard foam. hard enough for the laptop to press down by it's own weight, but not soft enough to let it compress the foam all the way.

                          all the above shouldn't cost too much. I would say try the CF card thing (very cheap) and the foam. if the work, then you can either swap the CF/HD when u need to, or get an external enclosure.

                            That flash thing sounds like it would get me some more db tolerance, but not sure about the pillow thing. Don't want to waste my time making it stable to have the screen crack, that is why I mentioned some sort of enclosure.

                            Your winsheild will break somewhere around 160 and it is safety glass, so I'm more concerned that the weaker components (hard drive is probably weakest) are maybe only 5 db or so from some sort of catastrophic failure (screen shatter etc. who knows?). During comps you see alot of strange stuff like wipers coming on by themselves but amazingly I have only heard of one oem ecu failure (bmw).

                              no, it wasn't a bmw, I don't beleive it. must have been a fake.

                              comps seem like an interesting problem. I guess at that kind of resonance components on the board maybe shaken out of their soldering holds (if they are hit at the right frequency).

                              So in trying to use as little electronics that are not designed for competition purposes, perhaps another way to do it is to stream the music somehow. or maybe you cuould use a high quality mini mp3 player, since they run off compact flash/solid state.

                              I'm just thinking out aloud here to help you find a cost effective way.
