Hey Guys - Long time reader, first time poster. I am attempting to develop a prototype of a new product. Part of this product will involve a good length of resitive wire that will generate heat. To accomplish this I cannibalized an electric blanket for the resistive wire and power controller. The problem is, I cut and quick spliced the wire and now I am getting an error from the power controller that possibly could be related to too much current flowing.
I assumed the resistance from the wire is related to length. eg, cutting and splicing the wire would not affect total resistance. Apparently I'm wrong as the power controller doesn't like it.
So the question is, where did I go wrong and how can I fix it? I thought about adding a resistor to the loop but I have no idea what the total resistance should be. So, my next thought is a simple adjustable power controller. However, I am short on time and I need to buy most materials locally. Is this an item radio shack could help me with? Any other advice or things I am missing?
