This is one of the most exceptionally brilliant puzzles we've ever seen. You can try Ri Sa's incredible Thermocouples sudoku here:

Rules for Thermocouples:
Normal sudoku rules apply. Cells separated by a knight's move (in chess) may not contain the same digit. Digits increase along thermometers, starting at the bulb end.

The puzzle was published first on our discord server (link below) and then on Logic Masters Germany here:
