      The system arrived with three power supplies and, though it's clear that this is good for reliability, the space taken by one of them proved convenient to store the power inverter necessary to get from the in-car 12V supply back to the 230V required by the system.

    I think slashdot just got trolled. An excerpt from his page as reasons for doing this:


    -multiple processors to ensure that mp3 decode is not interrupted by other process activity,

    -good internal storage capacity, including the ability to take advantage of software RAID for reliability,

    -large memory for good caching of tunes being played,

    -easily expandable to allow for future projects,

    -excellent support for Solaris 10, so that I can test bug-fixes, etc. while on the road if necessary. This also means that there is wide application availability (Oracle, great Java tools, etc.)


    Does anyone who knows anything about MP3s think you need large or multiple processors to handle the task? Do you need massive memory to cache the songs? No on both counts.

    Plus, the pictures on the site look like he just set his Sun server in the back of his SUV and snapped a couple photographs. No details on the hookup to the sound system at all.

    If any story ever showed the ineptitude of Slashdot editors, this would be it.

    Bah! to all those who made cracks about dayton ohio. You forget we host the Hamvention.

    Regardless, this guys got the right idea. Personally I decided not to put a computer in my car after ludacris sang about it. However, I still use a laptop and a digital FM converter to play my music.

    But really, think about it. Shouldn't this be the way car audio is headed. No need for damn disk. Also, CD are easy, frequent targets for thieves. If your neighbors don't see the wank stealing the server out of the back of your car, then they should buy your replacement. The e450 is a little big. I mean where are the 4 15"s gonna go. And wouldn't the vibration of my subs kill the E450.

    Even so, when you compare the price of a computer to that of the phatbox [phatnoise.com] there isn't much difference. Really the computer is more fun and could very well be put to more use. Think replacing the head unit with a touch screen that runs software you wrote to control the system. Who needs a dvd nav system. Put the GPS receiver and the software rigth on the computer. Think wireless file server so you can listen to the music on your car at your desk at work and then transfer all your hard work to the backup car system.

    This guy isn't the first person to put a computer in his car. He definitely won't be the last. While there will still be a solid market for component systems, I strongly believe that portable, multifunction car systems will become the norm within 10 years.
