Smile Cold Smoker Build

I don't have any detailed plans on paper. Kind of just built as I went. Its build from 3/4 hardwood plywood with a formaldehyde free adhesive so it does not off gas. It is lined with mill aluminum sheeting that has no oil coating on it. Simple 110V element, used the A-Maze-N smoke generator and a PID controller from Auburn Instruments. It works extremely well for cold smoking! Had to play around a bit with the wood chips as pellets produced way too much smoke and there is no sawdust fine enough locally that would burn slow and consistently. Ended up wetting the pellets to break them apart, then drying in oven. Kind of a PITA, but the results are excellent.
Was working on a home made PID controller using an Arduino system, where I could monitor and change the temperature from my cell phone. Has 4 analog thermometers in the door to monitor temperature gradients, 4 digital temperature sensors, automatic temp bumps, etc. All works really well, but the PID part of it is not working nearly as good as the Auburn Instruments controller. Stay tuned. Attached are some pics. Let me know if you have any questions and will try to help. There are things I like and things I would do different on the next build....
