I am tasked with a project to create a heating element using low voltage, such as batteries, to make a heating element to approx 100 degrees that will last for approx 30 minutes. It has to be approximately the size of a deck of cards.
Any suggestions would be helpful especially how to use a standard resistor to make a consistent 100 degrees.
Thanks
