 please help I want to build a safety device  , heres what i need it to do. I need a load sensor circuit which will sense a small hot glue gun when it is plugged in to a GFCI outlet :? , and turn an LED on, around 20 feet away. It would be nice if it could be placed in a double gang PVC weather proof box with two GFCI outlets.  Any help would be great thanx
