Did you see this yet? In it, this guy uses a wrt54g router + one
of the open wrt firmwares - ddwrt, iirc, some relays, and some iphone
mojo to control an rc helicopter from his iPhone.
How is this applicable to your question? I mean, besides being the
coolest thing I saw this week...
His little wrt54G is hooked to his servos on the copter via the
ethernet ports. This means he figured out basically how to fire
relays that are connected to the ethernet ports, without using an
I'd start by presenting your use case to this guy and asking for his
source code (for the ddwrt app he wrote) and more in depth info for
how he did what he did.
Sounds like a pretty cool project!
