DIY Solder Reflow Oven

I have already seen all there is too see on the internet on this matter (particularly, Ben Heck) and I am seeking guidance both in code and approval in my schematic.

I have decided not to use an LCD (although if I ever change my mind, it shouldn't be hard, at least in terms of hardware) and am using two Max6675's and thermo couples, as well as a simple toaster oven.

Can anyone confirm this schematic as well as give me advice on the code, I've looked at Ben's but its overkill for me. I am a simple man (honestly) :slight_smile:
