The sole machine that was any good was the iPod, and it excelled in every way, except for its lack of Ogg support.

      So I bought an iPod, and re-ripped all my CDs ( thank god, not too many ) to high quality MP3 and discarded my oggs.

      These are just the schematics (in PDF form), not gerbers.

      If you're thinking of "rolling your own", forget it. It doesn't make economic sense. Even if you did have the gerbers, making the boards would probably cost a minimum of $100. Then you'd have to buy all the components and solder them on. I don't know what the component cost is, but after looking at the schematics, I noticed that they use several highly specialized chips. You probably would not be able to purchase these chips yourself in singular quantities. If you could, you're now looking at a very difficult job in soldering them onto the boards. If these chips are TSSOP packages, you'll need special soldering tools, which cost several hundred dollars, and require some skill in using (which means you might screw up the first one or two). If these chips are BGAs, however, it's not possible to do those by hand. Unless you happen to have access to a BGA rework lab, complete with a reflow oven, and inspection tools, forget it. And I still haven't gotten into all the miniaturized SMD components that also have to be attached.

      Finally, this still doesn't provide you with a case, buttons, various custom plastic pieces, etc. The LCD might also be a special part. Also, don't forget the value of your time. A project like this would take a long time to complete.

      Your final "roll your own" MP3 player would probably not work, would be ugly, and would cost many times what it'd cost you to just order a Neuros II from their website.

      I'm a big fan of building your own equipment, but you have to know where to draw the line. This isn't like building your own Tivo/PVR, or CarPC. With projects like those, you just need to buy pre-made components (motherboards, power supplies, enclosures, hard drives) and slap them together, then install Linux and spend some time with customization. Fabbing your own circuit boards is an entirely different matter, and simply isn't worth your time unless you're doing something relatively simple, or are making something you intend to sell in large quantities.

    This would be an awsome product to hack on. I've been thinking about putting together a car-based mp3 player, and with the firmware now open and most of the functionality there that I want, this might be a better platform to work off of. I was originally planning on going with Mini-ITX hardware (or nano-ITX when it came out), Linux BIOS + LFS system on CF, and entirely custom software (with heavy using existing libraries). This would be much simpler, and result in just as good of a system.

  16. It realy comes down to UI, though... by incognitox · · Score: 4, Insightful

    I've got a Neuros...the USB1.1 version from about two years back. I gotta say -- it's a sweet device.

    -- I like the swappable backpack idea because it makes for cheaper upgrading and the ability for more than one person to use the same device with minimal difficulty.

    -- I absolutely LOVE the integrated FM broadcast. This hit the market before everyone and their mother was making add-ons for this functionality, and it's still a really handy feature. It means that _I_ always get to hear my music in other people's cars, because no one else has this ability!

    -- HiSi (the song-identifier) is a pretty nifty gimick, too, although of minimal use (more to the point is the built-in FM reciever...something that I think EVERY audio player should have -- it costs about 20 cents to include at this point, why not do it?!?!)

    (disclaimer at this point -- mine IS the old version)

    !!!HOWEVER!!!

    The one failing of the Neuros is in its interface. Navigation is painfully slow. You cannot queue up songs while it's playing. Organizing songs into playlists inexplicably takes about 3 or 4 seconds once you've decided upon a song and selected "Add to my playlist". There is no way to play a series of albums, so you are stuck playing alphabetically by song title, by artist (and then within the artist by song title) or album-by-album. See previous statment about creating custom playlists. Oh yeah, and for some reason, it takes about 3 seconds to boot each time you start it. My PC starts faster!!

    So, to put it lightly, the interface plain SUCKS! And ultimately, that's what matters. I love the tech aspect of this device. The open-standards are awesome (ogg support used to require a separate version of the firmware -- dunno if that's still true); there's a thriving developer's community which is fully supported by the company. Their customer service is phenominal (a broken mini-audio jack took 5 days to fix -- shipping time to Chicago included!). But the interface needs a lot of work.

    And the interface of an audio player is the make-it or break-it point, IMHO. It's what you see every day. How quickly can you play your music? Good interfaces are invisible. You don't notice that they are there. You just notice that you can get the job done and do it quickly. I think this is more important in the portable-audio market than anywhere else. If I have to make the decision whether or not to turn on my device because there is a 10-second lead-in before music starts and a 5-second end sequence, then they've lost me...

    I haven't had a chance to get my hands on a generation 2 device yet, so perhaps there has been a massive improvement. However, as of now, my next audio player purchase will be an iPod -- unless someone can point me to a better interface!
