So I finished building my zombie barrell pop up and want to have a 400 watt fog machine go off when the prop activates. So I have it plugged in all the time so it can fire on demand and it's warmed up correct. How do I make a relay to activate the switch on the fog machine to go off when the prop does. Can I go into a picaboo controller so it would be timed from that? Would it be timer to relay then out to 120v power cord to picaboo? Confused on this one. What relay would you recomend for this.
