I believe you want to look at X10 devices. Take a look in the Stamp Manual Index for a good explanation.
They are supported in Pbasic and BasicStamps, but it looks like Parallax is no longer carrying the devices.
YOU can use the BasicStamp with them or just use them with their own controller. RadioShack has sold them for many decades and the local B&Q in Taiwan is even selling these. Mostly they just control lights.
I would like to have a lot more, like security and smoke alarms and automatic watering. I am working on a different home automation network as there are some glitches with X10 for service like these. I am using CANbus. But that is another story and a bit more complex.
AS I recall, anytime you have a power transformer you cannot transmit or receive beyond it.
Below is a site that has something more powerful than X10, but on 110v lines.
The problem you run into pretty quickly is that the power-line is there to transmit power. 110 volt AC at impressive amperage, in fact. Thus, trying to get a digital signal to 'ride' on that power-line gets "too complex" pretty quickly. Not to mention life-threateningly dangerous if you do it wrong.
X-10 has long been one of the safest ways of going about it, but even then, to get a 'two-way' communication going is difficult. If that's "too complex" for you, then the level of hardware hacking to get a 'a little stamp net' on the power-lines is probably also much too complex.

My AC power-line transmits power at 220v.
Power is dangerous oh yes!!.·
OEM Value $20 each.(X 4),I get·$45w
A net(X 4 ('two-way')) $?¿ mmmmmmmmm.
The 2 Closest 8 to 12in apart
The Biggest distance 190foot apart, (out in the steal shed)
Wire is the cheepis way,
However, A BIG! Problem, "Not My House!"
I believe Power-line "carrier-current transmitters" is probably the way to go
Yup, that's the solution all right. Unfortunately, I don't know of a supplier of "current-carrier transcievers" (you want to send AND recieve, I assume).

been searh this site with Google
But Nope could not find what I was looking for
I saw an articulo one o 2 years ago the article was about controling lights
Has anyone have any Ideas where I can look
Thanks

yess
maybe it whas the X10
but to complex.
all I would like to do is
"Stamp-to-Stamp communication"
"a little Stamp net" ,maybe 3 or 4 Stamps
Thanks
