    A friend of mine put an old CD-ROM into his car about 2-3 years agao and it works perfectly. He has an very old diesel car and he drives on dirt roads ect yet he claims that it never skips or jumps. I can confirm that there was no skipping on normal roads as I heard it saw it working. He also never had any protection such as foam or whatever to absorb shock. I could not access the article so I am not sure about the way they did it but basicly my friend just hooked it up to a 12v power supply and wire from the phones jack to a small amp.

    a) Legality, say the information contained on the site is illegal (DeCSS), or maybe the site's author doesn't want to have it mirrored. Especially if the person depends on the ad revenue.

    b) Doesn't work all the time, say the website is dynamic, like that Perl to Flash website. There's no way to mirror that easily. Or the mechanical counter. etc.

    c) Its not the freshest information, the author could decide to revise the information. But the mirror might not reflect that.

    d) What to mirror, what not to mirror. Lets say that a site makes use of a lot of links to other sites, do you mirror those as well, and the links on those sites?

    Sometimes the internet doesn't work the way you want to, if this bothers you so much, you can devote your time to making a way to mirror sites mentioned on slashdot before they get slashdotted.

[never tried it, but I do believe it's possible] feed that 8086 machine an EMS memory card >= 1mb, an 8-bit network card, at least an EGA monitor, and about 20 megs of HD and you can use it as a (slow? probably) WWW-surfing box with Arachne [arachne.cz].

    If one wanted to, one could hook it up to an SCSI-bus equipped computer under the front seat - this would be well within the 6 feet you get under the narrow SCSI spec.

    It is kinda nice that this old player uses caddies instead of a tray. I have plenty of those tihngs and they keep cd's from getting scratched in the car when you fumble in the glove box.

    Perhaps this is a good thing. A few thousand angry customers who can't play their discs in their car player demanding their money back will be a good shot in the arm for fair use. The European copy-protection scheme along the same lines only failed in 3% of CD players, but this was enough that it was immediately withdrawn and shelved.

  • Not the same thing. The Empeg is harddisk based, that Kenwood is CD based.

    The crucial difference and the reason that I bought one is that the Empeg allows you to store ALL the music you own. I have with me at all times my entire music collection...

    There are other advantages. The Empeg's software is upgradable. In the near future we're getting WMA and WAV support (for free), and in the slightly more distant future voice recognition. The quality of the components is top notch, so it sounds very good and will last a long time. The UI is well designed and makes navigating your recursive playlists very easy. Also, it looks cool, with a whole bunch of impressive animated displays that move to the music.

    Also, it runs Linux... :-)

    I can recommend it to everyone, it's an extremely cool piece of machinery, and while expensive, it is very much worth it...

  • I just came back from a camping trip where I brought my old Thinkpad 760XL with me as an mp3 player. Here's the breakdown:

    -- Laptop (64MB RAM, 2GB HD, 24x CD) with Red Hat 6.1, xmms, gnome cd player (ebay price ~$150-$200)
    -- 1 power inverter ($50)
    -- 1 lime green power strip from Wally World ($2.00)
    -- 1 pair standup speakers ($20)

    Insert power inverter into stereo cavity. Plug in power strip. Place speakers behind truck seat on each side, routing wires through middle of seat armrest hole. Plug speakers into laptop, laptop adn speakers into power strip. Boot jukebox and enjoy.

    Caveats: My truck (92 Isuzu) just happens to perfectly fit a flattened (opened all the way) laptop under the seat without the keys being touched. Your vehicle probably can't do this.
    Power inverters do not like to be on when the car is started. So you'll have to switch the inverter off for a second, start the car, adn switch the inverter back on.
    Don't forget to run the vehicle every hour or so if your parked and listening...or you'll find yourself with no battery power

    This setup worked pretty well, you can reach down and use the keys to switch tracks, etc. You don't neccesarily want to be scrolling through a menu while driving 70, though. I had a very few problems with skipping, even on rocky mountain roads. Have fun!
  • Some of my friends used to use old toshiba double spin caddy drives because they had a test jumper on the back that makes them play audio cd's when you insert them. The eject button when pressed once would skip to the next track but if you held it down for a few seconds it would eject the cd. It was pretty cool. Anyway I just wanted to post that old scsi drives don't need a play button if they have a test jumper on the back.
  • How about a gyroscope cage mounted on compressing springs?

  • This brings up a dam good question. Where could one find a programable remote control? For example, something that would plug into the serial port and you could send basic commands via remote though your back seat to the laptop stored in your trunk? Now listen you could do some pretty dam cool things with something like this, provided it had some type of customizable interface like a C API or Perl Module ;)

    #!/usr/bin/perl -Tw
    use Remote;
    my $interface = Remote->new();
    while(my $command = $interface->param("input");) {
    if ($command eq "button1") {
    $interface->play_really_loud("*NIN*");
    }
    }

    Also anyone know where I could find one of those sexy little LCD displays? I know they are around, but forgot where. Something that has an open interface.

    I got 2 used laptop from work and they would be prefect for this sort of thing.

    Hrm wonder if I could get some type of GPS module for this type of thing... and map software... on linux or BSD.. Hrm

    I know! We could always get the mirror site to update itself on a relatively speedy basis - say, a couple of hundred times a second or so - and then we could be sure the site was up to date! And since all the Slashdot users wouldn't be hitting the original site a couple of hundred times a sec...

    What, you expected a serious response?

    OK. As above, but with a slightly more sane update period. RAruler's other points are certainly pertinent and important to address - legality is an issue that won't go away, and deciding the optimal level of information to mirror is not one that can be automated easily, especially in terms of dynamic content (how many sites out there actually use a lot of the metadata initiatives around?). Still, a little care could go a long way towards making sure that some of the neat and nifty people that Slashdot tells us about every day don't get crushed under the pressure of their 15 minutes of fame.

    This is a very valid reason to worry.

    Regular walkmans, for example have a bunch of ram built in as a buffer, so that if it skips, it waits while it plays data in the buffer. Typical walkmans nowadays hav something up to 30 seconds or 45 seconds worth of buffer. I also think that they are variable speed so that they can fill up the buffer fast, and then play of the buffer as needed. This has certainly been built into the car cd players.

    The second issue is the robustness of the units to take a beating due to vibrations. I think that CD Roms are more fragile than car CD Players, but this may be debatable. Certainly long term durability is an issue. How many times do you tap your computer with a rubber hammer while playing your favorite tunes? Would this even be wise?

  • I know you are kidding, but considering the fact that installing MS-OSes is not always easy (think NT4) HOW-TO's on that subject might even be very useful. Now the installation works quite well most of the time, but optimizing it, and tweaking it to your needs helps. Correct partitioning (yes, even that is *very* usefull on a WinOS machine! Especially if you want to keep your data safe), ect.
    Explaining to joe-normal-user that all those icons in the icon tray *eat* memory and that if you don't need them you can kill them (Run/Services in registry), explanations of how to keep your start menu clean and small (removing README, docs, helpfiles which you can access from the program itself).
    Well now that I think of it, I should get started ;-) On the other hand, nobody who would *need* this stuff would ever think of searching and reading such a HOW-TO...
  • Don't get me wrong, I like NT4, and it installs very well. Just don't think that you can put in the CD and wait! That won't simply work, I've never seen a machine that you could install completely with all drivers wouthout surfing like a madman.

    Besides, you did ignore all other things I said (tweaking, partitioning, etc). I was not talking about soley the installation of the bare OS: I don't call that an installation, but raw material to work with.

    Besides, people call "the friend who claims to know everything" all the time, even for Windows 9x, and guess what: if *he* fucks up, they call me! Or go back to the shop where the will put in the restore-CD and charge big buck for it.

    And no, Linux is not ready for the broad public, and I never claimed that, did I?

  • I know, but you know what you are doing, don't you? Linux has the advantage that you can get into the config files with a bootdisk, repair your mess, and reboot. (Which saved my *ss many many times because in Linux i'm just a newbie!)
    With windows, forget that, it's in the registry anyway (Yes, I know, regedit works under command line and you can load .reg scripts). The only option is to reinstall, and best not over the old installation because risks of contamination of the problem is high.
    Also Windows tends to freak out on unknown hardware, but Linux just ignores it (the better approach IMHO)
    So technically, Linux never screwed for me because a reinstall was not needed, but it is just inherent to the way it works.

  • There is another potential problem to this if you were thinking of hooking it to a remote computer unit.

    Most older CD-ROM drives (not the really old ones w/ the proprietary interfaces), but the ones that use EIDE as an interface are restricted in bus length. I think the longest an EIDE cable is spec'd for is 18". You might be able to push it to 1 or 2 feet, but beyond that you'd get consistent errors.

    Now if someone was familiar with the EIDE bus, you might be able to hack an ad-hoc controller and make a crude interface for the player (w/ a cable no more than a foot or so), to tell the player to play, stop, pause and skip tracks, but outside of that, it wouldn't be very useful.

    And as others pointed out, vibration dampening might be a problem. Neat idea though.
  • Here's [darkness.tj] what I made a few months ago, using my CD-ROM drive, and a handful of components. It's simple, and works really well, and doesn't need any computer PSU's or Inverters or anything like that, since cars supply ~+13v anyway. The only trouble I've had is with the crossovers, but I'm going to build an active high-pass filter for the front speakers, instead of passive.

    I've seen someone mention the problem of skipping when going over bumps. One could easily just switch to a CD Player that already has skip protection (through a read ahead device). However, there has to be a way to stop this.

    I've seen someone mention putting it in foam or something like that... That might work, but wouldn't it still bounce a little? If the foam is even relatively stiff the player will just bounce with the car.

    What about using the foam in one of these pillows [ezboard.com] to cushion it. Also, put it in a case attached to two wires so it can swing back and forth when the car hits a bump... I saw cup holders like this once. The drink wouldn't spill because they swung back and forth and stayed level... at least most of the time.

    Hopefully those measures would stop most skipping.

    I guess the good thing is that most computer cd-rom drives don't need to be attached to a computer to play CD's... simply hook up the power, and push play.

    Shock is definately a concern, but nothing a little creative mounting wouldn't overcome.

    Personally, however, I still like hooking up my MP3 player to the system instead... no shock concerns, easy to mix and match tunes, etc. If it wasn't for the sticker-shock on Flash cards, it'd be ideal.

    First, most all CD-ROM drives after 4x don't have a play button and won't automatically start playback when an audio CD is inserted.

    So this means you're going to need someway to send the IDE signal, which would probably involve, at least, a microcontroller although I'm not fully aware of the ATAPI spec and you may have to make the device completly physical (e.g. go through all the init routines) to even get to the point where you can send a command.

    Second, these drives, as mentioned don't have skip protection. Todays in dash CD players have read ahead of 45-60 seconds or more, because this is what it takes to get even marginal performance while driving over gravel in your SUV.

    Personally, I built an in-dash MP3/CD player using an old Sony VAIO 233 MHz system for my friend. The CD-ROM which came with the system was used, and in this case it already had mechanical skip protection. I used the LCD that came with it and bought a digital touch screen kit and connected this up the parallel port. To completly prevent skipping, I extracted the selected CD track to memory as it loads, at about +120 sec into playing buffer. Works very well. This was in a Jeep and he's told me he hasn't got it to skip. And yes, it runs Linux off an ATAFlash IDE card (no noise!).

    In reference to the original post, you don't have to be a N.A.S.A. engineer, all you need is a laptop and some time (a few weekends).

    By the time you're finished looking for your obstruficated CD-ROM and forcing the thing in your dash, you'd might as well been better purchasing a $165 car player as you'd be adding no addition functionality.

    By no means am I an EE grad, student, or even an electronics hobbyist, so I very well could be wrong, but the hack seems simple enough, and the site is /.'ed, so I can't compare notes. You probably have a 12V DC circuit in your car, and The wire colors on CD Audio cables explain themselves... what do red and white mean in audio components? In electronics, what does black mean? There, you figured it out.

    This is something that is painfully obvious, although few, if any have actually done it before. With the right phrasing, you just might be able to pull off a patent on the idea.

    This site is good, but here's some even better tips:

    (I've been using an old CD-ROM in my car for ages, here's my experience)

    • there's no need to stuff around with heatsinks! Just mount the 7805 so that the back of it is firmly against either the CDROM's housing or a good piece of metal in the dash. This dissipates the heat well enough, and electrically there's no worries in a negative earth car. (almost all cars in the last 20 yrs.)
    • Not all CDROM's are created equal. Experiment with different drives - some are excellent! I've got a "Diamond Data" 12x, which actually seems to have a (small, only fraction of a second) anti-skip buffer, and you can see the disc rotating at 2x. It also has nice big rubber shockers inside!
    • "alternator whine", the enemy of any in-car electronics can be particularly bad for these. (you can tell if it's this because it only happens when the engine's on, and changes pitch with engine revs.) Use a capacator across the power supply, but there's no need for ridiculously big one like for stereos. If it's still too bad, use a coil as well, these are commonly available at car shops as "noise suppressors".
    • experiment with different bumps: most CDROM's are good at withstanding bumps in some directions and not others. Test yours on the bench first, using just the computer's power lead and headphones. figure out which bumps are worst. Then when you mount it in the car, try and allow for some padding in that direction.
    • security: I deliberatey removed the flip-down cover from where the tray comes out of. It still works just fine, but it looks like a detachable face unit without the face! (but let's face it, if someone does nick it, it's cheap to replace)

    • Mine has been happily working for about 2 years like this, and with some rags at the sides as padding it's better over the bumps than my friend's cheap car stereo.!

    IDEA: (for the enthusiastic, probably even a money-making idea): It would be possible to use a microcontroller to send the play command to the IDE port, i'm just not sure how much of the bus you'd have to implement or how expensive it would end up being.

    Good luck! (but be careful...that site describes what can happen)
