Hello. I am totally new with electronics and need help.
I need to heat a small thin piece of rod around 1mm in diameter and about 5-7cm long and raise it to a certain degree lets say 50 degrees C and keep it at that degree with maybe 2 degrees tolerance until a switch is turned off. I assume that the electric power required will be minimal due to the small section that need to be heated up and can be done with a small battery.
I would love it if there was no easy way(such as a rotating dial) to change the temperature after the circuit is made.
Also, how small of a volume would the whole circuit take up excluding the power source assuming it is made as small as possible(assuming multiple layers of circuits)?
Is it also possible to heat maybe 1cm at the end of the rod only or does it require the whole system to be heated up uniformly?
Thank you so much in advance.
