Would it be possible to make my own small heat pad that would work with a 120v Sunbeam electric blanket controller? It's 180W style M85AP. I don't believe I have any nichrome wire, just some solid copper wire in a couple different gauges. Not sure if that would work or not so any advice would be awesome. The pad doesn't need to be very big I mean just big enough for my grandmothers ancient cat to curl up on at night. He's one of the bigger cats I've seen but like I said he's real old and skinny, oh yeah and I live in southern OR so it doesn't get too cold here. Anything below 20°F is pretty rare and only gets to freezing or a lil lower ~20x a year.
