I've got a project careening in my head to build a heated magnetic stirrer. How easy (or hard) would it be to use the heating coil from an old hair dryer?
My current idea is to build a cube from soft refractory bricks and embed the coil in the top. The motor for the stirrer will be inside the bricks, protected from the heat. A raspberry pi will control the speed of the motor and the temperature of the coil via PWM. What do I need to consider to carry this out?
