  1. an atom based nettop on Low-Power Home Linux Server? · · Score: 1

    Hi,

    I have an atom based nettop (eeebox 202 from asus :http://usa.asus.com/product.aspx?P_ID=QUObl5lSRQQ3lSqJ) it make virtually no noise and use very low power.

    the CPU (atom 1.6ghz) could be seen a slow but is perfect for ma use:

    i have installed on it a linux distribustion and it provide me this services:
    - file server (samba/nfs)
    - apache server
    - video playback with XBMC, as the box is attached behind my TV on the vesa support. (max 720p)

    if you need better video performance there is new version of the box based on ATI or nvidia chipsets.

  2. Telescope not absolutly needed on Adapting a Webcam for Astrophotography · · Score: 1

    Hi,

    you don't need absolutly a telescope.
    By using Lens of a regular SLR film-camera
    you can some nice pictures of deep sky objects
    (the CCD captor is so small than it "multiply"
    by 10 the focal of your lens (if you compare with the size of a regular 24x36 film)

    Yes, picture of the moon or some bright planets is an old stuff.

    But picture of faint Deep sky object is some thing that was near impossible 2 years ago without a very expensive astro-CCD camera.

    But now with the work of Steve Chambers
    (http://home.clara.net/smunch/wintro.htm ) and a lot of others one you can do good deep sky astrophoto.

    with a cheap Webcam
