Tell us about yourself!
I did not build the TC4 per the schematic, I modified it by taking out parts which I do not need, I call my modified version the TC4lite, the schematic is in the gallery as well. Yes I used capacitors across my thermocouples as I notice some noise in my reading. I did not take note of the pull down resistors though, it is in my design and works just fine; I would guess it is to protect the ADC if the pins were left floating.
Hey I am using 50mm length K-type thermocouple. Yeah glad you give it a go! Let me know how it goes!
Haha eagle eye indeed! Yes it is double walled. I designed this to roast 1kg of green beans, unfortunately the heat capacity just isn't enough, hence the double layers. It does improve a little but given another chance, I would try to find a reasonably thick stainless steel over the double walled.

Looks like you are doing quite well. Machine taking shape yet?
Yes that is why I am already planning my next build. All stainless steel, but I might keep my current traffic cone, looks cool!
You are welcome! My only issue is I don't have the ability and tools to cut stainless steel and perform stainless steel wielding. I am planning send some of my next design to a CNC shop and get them CNC out or lazer cut. I don't really know much about Khaldi Fortis but if you have a mesh between flames and drum, might be useful in catching chaff dropping down.
