Description
Adds a block, the Dedicated Block Update Detector. It emits a 8 block strong redstone signal for 1 second when a block update occurs next to it. (That is, an adjacent block changes, like a melon growing or a wall being mined.)
Does not react to redstone-emitting blocks, to avoid infinite loops.
It can be crafted as follows:
A redstone lamp in the center to take care of the logic, surrounded by 4 redstone torches for signals and embedded in 4 regular stone for the frame. (Not cobblestone.)
