IF you can find October Nuts and Volts magazine, there is an article
that would fit the bill exactly, and more importantly... Cheap.
LAMP CONTROL WITH YOUR STAMP - Jerry Reed
Get some bright ideas with this simple "contractor's delight" set-up
that works not only with a BS2 OEM board, but will interface with a
PC parallel port or other digital outputs, as well.

I am working on a circut which uses a EEPROM made by Parallax to
animate a string of christmas type lights. I intend to have four
separate 120vac outlets that are switched on and off (dimming would
be nice) by the EEPROM. Obviously, the outputs EEPROM can not
handle
much current at all. I thought of using the EEPROM to control a
small
relay and hook the contacts of the small relay to a coil of a
larger
relay to turn the light on and off, but I would like to use some
kind
of solid state circut to control the 120vac (that way I could
implement dimming). Any thoughts on how I can control the 120vac
with
a small current. Sorry I don't know the exact peak current the
outputs on the EEPROM can handle.
