Ceramic Kiln/Controller

Overview

I'm building an arduino based kiln controller for driving our Kiln.

Goals/Features

• Add mode button for Candling. (raise temp to 190F and maintain temp for 12 hours.)
• Add mode buttons for Timed Firing (not sure how this might be useful, but then I know nothing of ceramic arts either. maybe glazing?)
• Add mode button for Gradual Heating (slowly heat the kiln as opposed to full electric on.)

Materials/Links

• Arduino Uno
• Thermocouple Amplifier MAX31855 breakout board ($20)
• Type K High Temp Thermocouple ($28)
• DC-AC Solid State Relay SSR-40DA 40A 3-32VDC 24-380VAC w Heat Sink ($24)
• DigiSpark Relay Shield (because I had spares and am a little afraid of hooking the SSR directly to the arduino without a transistor circuit; also I'm lazy)

Technical Details

• Status: reading temp and displaying it on lcd display; I'm waiting on the SSR from ebay to start integrated kiln testing. The high fire Type K thermocouple arrived and is installed.
