USB Alien DAC


[blip] let us know about this nice little project. The Alien DAC Project is basically a DIY USB sound card/interface. [Pictured is one built by cook on head-fi.org] It uses a TI PCM2702 at its core with some supporting chips for power regulation and virtual ground for the analog audio signal. It’s small and should do the job. If you’re really interesting in taking it to the next level, check out the DAC-3. It’s like the big mean older brother of the Alien DAC. That thing is rack mounted, has Optical, Coax and USB inputs.
[If you run across any more floating ads, let me know. They shouldn't on the site, and we're trying to take care of them.]

    If anyone is interested, Head-Fi is running a group buy on boards for this bad boy: http://www6.head-fi.org/forums/showthread.php?t=191830

    Should be pretty cheap ($3/board or so plus $30+ for parts). I’m going to build one as soon as I confirm that it will work with linux.

    i got a float over, too. at first i was like, WTF? but then UNDERNEATH IT, i saw your “let me know” message.

    lol, i thought it was kinda funny

    just got one from
    http://amch.questionmarket.com/static/tribal-150×200-9l-eng-nul.gif

    In any case, it will be nice to have a sub $50 dac that actually can produce good sound ;)

    I also had a floating ad, and all I could think was WTF?
    So there is still a floating ad and I hope you take care of it.

  11. shawn says:

    yes still a floating ad, hum instead of getting rid of it maybe you can hack it and make it usefull?

  12. Ryan says:

    i havent seen any floating ads. perhaps the people seeing them have some kind of adware on there pcs?

  13. grayskies says:

    AdBlock ftw.

    Really nice work!

    How would this compare to say, a Griffin iMic?

    They have dipped to 19.97 on clearance at my store and I get 10% off that to boot.
    I was thinking of picking one up to fiddle around with.

  15. Dan Butler says:

    Yeah, floating ad, floating ad….some survey thingie

  16. radioactivecow says:

    floating ads:(

  17. jason says:

    floating ads… “QuestionMarket” is the logo at the bottom that rivals fine print on money

    The pcm2902/2906 from Ti is the same thing, except it also adds both analog and digital audio INPUTS without changing the circuit much. PCM2902 is 3v and 2906 is 5v. Just been told that the audio chip in it doesn’t work as nicely as the specs for the 2702, but audio input is great as well.

    There is a new group buy (the old one ended) for the PCBs for the Alien DAC going on at http://www6.head-fi.org/forums/showthread.php?t=201915

  20. blip says:

    Just wanted to let everyone know that I have confirmed that these will work with Linux… So all of us pengiuns out there don’t need to be left in the cold The group buy is still open I think so if you are interested, get involved before it is too late.
