I was thinking it would be easy enough to adapt a wall wart to power the unit at the desks - here's a 24V 750mA unit for $13.50 each:
http://www.powerstream.com/24-volt-dir.htm The DDW-220 pulls 300mA at 20VDC. Either attach a socket (Radio Shack) to the power lead or hard-wire the wall wart. Or perhaps you could run power over another pair of the old copper, if available, to power multiple units from a larger DC power supply in the datacenter.

It's rather more of an industrial design that is suitable (DIN rail mount, needs DC wired-in power supply), but might be adaptable for our purposes. I having a feeling it's not appropriate for this project, but it may come in useful for others. :) -- Ben _______________________________________________ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
