How to: Digital Kiln PID Conversion Project
I took an old Duncan ceramics kiln and converted it to run on a PID controller. The process is simple once you understand that this is essentially a really large oven. The basic components are the same, it can just achieve much higher temperatures.
As with anything involving high voltage. If you are not a qualified electrician I cannot advise you take this on. High voltage is dangerous and should be handled only by those who understand it.
