I have a project that I need some hardware pointers for. I need to build
some Centos "appliances" (dedicated boxes to do one thing only).
Target
cost is under $250/box.
Need:
OS: Centos 5
Hardware Cost: less than $250 USD
USB: at least 2 (not including keyboard)
Memory: at least 128K
Storage: prefer flash (USB stick OK)
Network: 10 Base T
Want:
Height: less than 4" (fit on a 3RU shelf)
Width: less than 10" (slide keyboard beside CPU on rack shelf)\
Display: 80x25 (or better) LCD on front of case (comes that way or I mount
it there)
Network: 2 x 10 Base T
Application (in case anyone cares): Move better-than-FM quality audio
across a leased audio circuit with delay under 10 seconds. No Internet
exposure. Obviously one box is required at each end, and the encoding box
works much harder than the decoding box. Software to run will probably be
Ices -> Icecast -> network -> mplayer. Will be using USB audio
interfaces,
probably something like the M-Audio Fast Track Pro. Because of the nature
of the application, once it is booted up the only disk activity is
occasional logging when there is a problem with the connection.
Any advice, web links, battle scars, or advice gladly accepted.

Obviously one box"leased audio circuit" meaning ISDN ? your $250 target price includes not only the built in flat panel and audio adapters but also the ISDN adapter? sounds like you're trying to reinvent the Telos Zephyr. http://www.telos-systems.com/?/xport/default.htm have fun!

Or for just audio, their soundbridge products that are more expensive but some include speakers. Development specs are available for the soundbridge along with source for gpl'd code included with the netflix box. Not sure about development on the netflix box, though. Might be worth $99 just to take it apart and see what's in there. -- Les Mikesell lesmikesell at gmail.com
