”Exclusive Or-Gate“ in Minecraft (XOR)

Build two input-lanes. A lever can be used as power-source.
exklusiv_oder_gatter-1

Place three blocks behind the input lanes, like you can see in the picture.
exklusiv_oder_gatter-2

Place redstone-torches on the other side of the blocks.

Place two blocks over the two torches at the border.
exklusiv_oder_gatter-4

Connect those two blocks with Redstone.

Install two redstone-lanes, starting at the border-redstone-torches.
exklusiv_oder_gatter-6

Invert the signal by placing a block at the end of the lane and…
exklusiv_oder_gatter-7

…by adding a redstone torch at the back of these two blocks.
exklusiv_oder_gatter-8

Connect the signal of the torches to get the output-lane.
exklusiv_oder_gatter-9

Case 1)

  • IN 1=OFF
  • IN 2=OFF
  • Results in: OUT=OFF

    Case 2)

  • IN 1=ON
  • IN 2=OFF
  • Results in: OUT=ON

    Case 3)

  • IN 1=ON
  • IN 2=ON
  • Results in: OUT=OFF

    Case 4)

  • IN 1=OFF
  • IN 2=ON
  • Results in: OUT=ON

    So all in all, only if both inputs are different, the output becomes positive.
