using ipod touch to control relays
it's been a while since i've been around but i have a new project i want to get started. basically i want to use an ipod touch as a very simple media player on a boat... simple enough. the other thing i want to do is control a ballast system (6 pumps) using the ipod. Are there any applications/hardware that will let me do something like this? My initial idea was to use fusion brain but i'd love to stream line this to an ipod and one other piece of hardware to do the switching as well as having a small display that i can incorporate into the limited space on the dash.
thanks in advance,
