With another baby due in February, I'd like to make a blanket/towel warmer. Something along the lines of a small cabinet with the heater in the bottom drawer, and air vents to allow heat to rise to the upper drawers. Easy enough.
The concepts of control are, as well, easy enough, but I'm going in circles on choosing what to use as a heating element. Since this would be going in my home (in my baby's room, no less), I'd like it to be as safe as possible.
One of my thoughts is to buy a power resistor with a rating of 200-300 watts (they're cheap enough), and only run it at 100 watts or so. A fuse would, of course, be used, as would multiple temp sensors, and probably a thermal fuse as well.
It would not, of course, be run directly from the mains. I have enough PC power supplies around that I would probably use one of those, and control the 12V line via a FET.
Any thoughts or feedback on that plan?
