Smoke Machine Modified for Digital Control

This year, my kids and I are working on some motion-activated effects for the trick or treaters.  As part of that project, we have some desired effects we want to be able to remotely control.  Most of them (i.e., sound effects, lights) have been easy to create.  However, remote control of a smoke machine was more of a challenge.  This project details how I combined a Powerswitch Tail 2 DC Controlled Power Switch and 400W Fog Machine  to create a digitally (i.e., computer/Arduino)  controlled smoke machine.

Full details after the jump; here's a video of the smoke machine in action, connected to an Arduino using infrared motion detection as a trigger.
