SISO (1 input, 1 output)
below block breaker

Sign parameters

Third line: (optional) block ID of the block to break.



  1. rising edge


  1. none


  1. This IC breaks the block immediately below the block the sign is on, not the block below the sign. If you set it up on the floor, you might not notice that the block below it has broken.
  2. It will also not break bedrock even if you specify bedrock in line 3.
  3. If you specify which block ID to break in line 3, and the block below it is not that block ID, it will not break the block.
  4. This IC depends upon a change in state from low to high. If the sign is too close to a redstone circuit that holds the sign state high, the state won't change and the IC will not function.
