Marklar,
I have a bit of a problem with X10 products - most of them are working on 110v and I'm using 220v (I'm from Israel).
there are 220v products but they are 3-5 times more expensive than the 110v ones...
I found a way to modify them in order to make'em suitable for 220v but I think it will take a lot of time an effort...

isn't there a simpler way of controlling and dimming light (beside X10) or is it the cheapest and easiest one?
the link you gave with the X10 rs232 device, is it something similar to this one?

because if so, there's already a library for that using this psc05/tw523 device...
something else - most of the shields, when you install them on the Arduino card, also give you access to the I/O or analog connections.
my question is, are those connections still can be used or they are just there for being like Test Points (for taking voltage readings and stuff) ?
because I think the shield is supposed to use these connections for whatever his role is, right?
