GAAK!!! - there are readily available devices known as "Solid State Relays"
that allow you to switch 117 Volts from a DC logic level.  They may be more
expensive then do-it-yourself versions, but that 117 VAC can get real nasty
if you f**k up.

Looking in the current Mouser Electronics Catalog (1-800-992-9943) I
find a both solid state relays and digitial I/O panels.

The solid state relays (Page 153-154) are available in various power and
voltage ranges - you probably want the ME433 or 519-RP units, which run
from $15 to $30.

There is also a modular digital I/O system (Page 151) with an 8-module
mounting board for $70 and AC-OUTPUT, AC-INPUT, DC-OUTPUT AND DC-INPUT
modules listed for $17.50.  If you want to experiment or set up a permenant
control for multiple devices, this would be a good bet.
