Just posted about ArduinoWaker (Arduino + EthernetShield, for wakeonlan & turning USB-controlled power strips) here:http://www.arduino.cc/playground/Main/ArduinoWaker
Please post any comments / discussion regarding this here
PS: And just one more thing
Was trying to see what possible alternatives there could be for a similar device; the only thing I think comes close is one of those new "plug" computers, like the GuruPlug Server
- in the sense that they are small, always on, and spend little power; but while they are full servers, they don't have any digital outs to control power strips with
(although I cannot imagine fitting them with a DB-25 would be too difficult)
So just as a little comparison: where I am, just a GuruPlug (power supply adapter included) would cost around 120 EUR; Duemilanove + Ethernet Shield + USB power strip w ground + power supply adapter would cost around 105 EUR (disregarding postage and packing, but including VAT).
Now, of course I do not want to start a discussion comparing apples and oranges here - just thought it was interesting to compare alternatives for devices that could fulfill the task of "waker"
(although, arguably as say GuruPlug does not have any controllable digital outs built in, such comparison is not necessarily very profound either)..
