beagle board a brilliant ideabeagle board a brilliant ideaPosted Feb 16, 2009 12:22 UTC (Mon) by aleutia (guest, #56538)In reply to: If 8 watts is still too high by pjm Parent article: Aleutia E2: low power to the people
Aleutia is reading this and thanks for pointing me towards the Beagle Board. I'd come across it before but seeing Ubuntu ARM running on it has re-ignited my interest. USB-power means we can offer a single AC (possibly 12V DC) USB power hub to run a classroom of them.
Ordering one and will comment if we commercialize it.

beagle boards and other low-power systems Posted Feb 16, 2009 23:10 UTC (Mon) by pjm (subscriber, #2080) [Link]
http://elinux.org/BeagleBoard has lots of useful information. In particular, note the differences between the currently-available revision B, and revision C2 due "end of March", such as USB HOST (EHCI) issue.
The display is typically a significant drawer of power, so note a couple of issues relevant to output: the Beagle Board has HDMI and S-Video output but not VGA. See also the above page's comments on interfacing to raw LCD panels.
Also of interest is http://linuxdevices.com/news/NS7369895239.html (which would be a competitor for Aleutia) and related products such as the eBox systems (note there are both DX and earlier SX versions) and their associated underlying systems-on-chip. (Note that it's the system-on-chip that has the low power consumption; I haven't found any claims as to how much power the computer as a whole uses, making me suspect that the system as a whole doesn't have so impressive a number.)
