    But where'd he get power for this thing? I would think it would require massive alternator upgrades for it to work, but I see nothing of the kind on his page. The only hint is that the inverter link goes to a page suggesting that it needs 30v power, while I thought car power was universally 12v.

    I can see this solution for a motor home where a generator can be available, but not a minivan.

    This seems like something that must have not cost much to do, or he would have done better than that crummy cassette adapter. That implies that standard power must have worked (?).

    Strange.

      From the page:
      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.

      And from the inverter page:

      Provides 230V AC output from standard cigarette lighter plug

      30A does not equal 30V. A cigarette lighter probably isn't good enough for the full rating of this invertor (mine, for instance is on a 20A fuse along with the interior lights and stereo), but it's possible to tie in to the alternator output directly.

  2. Slashdot got trolled. by jared_hanson · · Score: 4, Insightful

    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.

  3. Power Problems by whataboutMike · · Score: 5, Insightful

    One more evidence that it might be a hoax: the E450 requires ~1600 watts of power and the power inverter that he says he uses provides only 300W... A difference of about ~1200W...

    If you read the article carefully, you would have noticed that it cost him a whopping $0. For that much, how can you go wrong? It may not be the wootenest system ever, but its definitely neato.

    He could've sold it on eBay and bought at least a half dozen brand new iPods. On the other hand, it does pain me to see that the e450s we bought about 4 years ago for $38,000 are now going for $2000. We should've bought a Mac as they hold their resale value better.

  5. Re:What's *not* necessary by DJStealth · · Score: 4, Insightful

    Once I heard he had a laptop to manage everything, I realized that this whole thing must be a joke. He probably had to transport the E450 between branches at work, and decided to take some pics of it.
