What would I need for a murphy bed, that when lowered says "goodnight" once on a pressure switch ?I know there has to be some sort of recordable electronic device that plays back. Something similar to a recordable greeting card, but that I can hook to ac or maybe a 9 volt battery. And what would I need for a switch, to trigger the voice and then shut back off?
