Greetings All, I know this is silly but here it goes: My wife and I keep our bedroom un-heated so it gets cold in the winter. An electric blanket warms the bed before we get in. My wife would like to keep it on all night instead of using all the extra covers but is concerned that the "electrical magnetic field" emanating from the blanket will give us cancer or something. I mentioned that it's low frequency AC that people are all worried about and we are subjected to it all day from wires in the walls etc so why worry about the blanket? I know it's closer so any effect AC might have would be greater from the blanket but sheesh! Then, I foolishly said that if the blanket were run on DC we wouldn't need to worry. Now she wants me to fix the blanket to run on DC. I took apart the control and it seems like the heat control is just a bi-metal switch and the light is a little neon bulb. Is there any reason why it couldn't be run on DC? I envision a full wave rectifier and a capacitor. And it looks like there is enough room in the control for these extra parts. Is there anything inside the blanket itself that precludes Dc operation? Thanks, Eric R Snow, Machinist, electonics hobbiest
