Hi Peter,My idea is to use an old oven heater like the picture. With respect to
the PID controller, maybe it is cheaper to do it manually, without writing
code.
I want us to design a 2 meters long oven, containing two heaters and two fans
(for example). What I intend by this?, I want to save the maximum possible
power. So with small parts, we only use medium oven
