My name is Helena Parewyck and I am working on developing a USB operated/rechargeable battery heated saddle pad for riders to use on their horse.
I have bought wire that can be used for heating and currently am trying to find ways to attach it to my foam pad saddle (1inch thick), best ways to heat it so it is warm enough (not sure a phone battery would give enough warmth).
Also I want to learn how to solder and how to get this working.
Any suggestions? Or willing to help me out on this project?
