Homebrew PCBs

Or maybe: -

This thread is related to Stefan's toaster oven mods to be able to bake direct inkjet pcbs; and perhaps to double as a reflow oven (my objective). BTW, I bought the MAX6675 (A$8.64), much happier now, thanks to help from members of this list. BTW2 a diode compensator requires a isothermal block at the cold junction; the MAX6675 gets away without this.
