I've had a manual kiln for a while now and it is kind of a pain in the butt to use so I finally made it digital. Here is how I did it with pictures so hopefully somebody else can take the digital plunge. The kiln I started off with was made by Satellite Mfg. I used the thermocouple that came with the kiln. To finish the project I bought a toggle switch from Home Depot, a fan from Radio Shack a solid state relay and PID controller from lightobject.com, You will also need some wires and wire connectors.
