I need some advice on how to wire up a homemade mirror heater or demister. I have an old toaster which I have gutted to get the heating elements. I also have a few old wallwarts to power the thing. Is using these wires the right thing to use as a heat source? It doesn't have to get hot, just slightly warm. What kind of circuitry will I need to warm up the wire?
I also got some modelling latex to embed this wires in to make a heating "pad" for the mirror and to insulate it. Is there a better material I can enclose the elements in.
