Home-built Fluid Bed Coffee Roaster - 500g Roast - PID - Artisan Scope 

Home-built fluid bed coffee roaster. Now Artisan is fully controlling the heating element, and it's able to decently follow the background curve. 500g roast (516g to be more precise).
I also made a backup switch. If Artisan crashes, I can toggle to Manual mode so the Autonics TC4S PID controller takes control of the SSR, and I don't lose the roast (already happened).
