I don't have time, who wants to finish this?

Because the UPC board can measure temperature with a thermocouple, it can very well be used as a hot-plate or reflow-oven controller.
By the way, I prefer a hot-plate because you can rearrange the SMD components during soldering, which is often necessary.

You only need an extra (low-cost €5) MAX6675 thermocouple board:

I haven't had time for the software yet, but there are several open source programs available. The 0xPIT / reflowOvenController on GitHub is very suitable because it also uses a TFT display. I think that only a small change is needed to make it suitable for the UPC board.
