How fast can a lamp cycled on and off

[rick]

Using the SDK, how fast can you cycle a
lamp module on and off?

[Charles Sullivan]

The speed is primarily limited by the rate at
which the signals can be transmitted over the
power line.  Each component of the
transmission takes about 0.6 seconds, so:
Address A1, A On, Address A1, A Off
would take about 2.4 seconds.
But if you wanted to make just a "flasher",
you could eliminate all but the very first
address and afterwards send just
A On, A Off, A On, A Off, ...
and cut the cycle time to about 1.2 seconds.

Are you thinking, like I am, to build a
christmas display like the one on Ohio that
has been all over the Internet? (Wizards of
Winter)

Before you go off to far on a fantasy of
creating a Christmas display using x-10,
follow the like below to see how this family
has been doing their for several years.
Good luck.  It�s a reality check

Did any of youz guyz look into
www.PhidgetsUSA.com?  It's USB to I/O
modules, LED displays, etc.  I'm not sure if
you could get the response time needed, but
there are PCI I/O cards (like the ISA
http://www.lindsaylights.com/ people used).
We're going to have a haunted house in
Milwaukee WI and we'll be sportin' probably
X10 stuff since speed is no issue... or
Phidgets stuff... we'll see.
