Kirk, Do you think something like this could be used to control the temperature of a smoker cabinet with 500 watt heater? I've been wanting to build something that is very cost effective that could be plugged into a laptop via usb or something and control the smoker heater... Being electrical engineer challenged any suggestions would be helpful.
