Building a heating element for battery use? Answered
I am new to the world of tinkering but I would like to attempt something. I am trying to build a portable heating element that would only need to reach about 70-100 degrees and be attached to a piece of metal to allow the metal to absorb the heat.
Now with this idea I am trying to make it 100% portable, thinking of utilizing 4 AA batteries and a switch so the element is not required to be on all the time.
I thought about pulling an element out of a cordless curling iron or something and trying that but was not sure if it would reach the correct temp or be able to last about a month or so with moderate use.
I am not very well versed in the circuitry world so the amps - volts thing is a little fuzzy for me so I apologize in advanced if I do not completely understand your responses.
