Scaffolding provides the upward counterpart: Each scaffolding block tracks how far it is "overhanging", that is the distance from a column of scaffolding which is actually resting on a block. In Java Edition, this change can be detected by observers, allowing for instantaneous downward transmission by moving a block over or away from the topmost wall. Starting from Java Edition 1.16, a Wall with a tall center post (due to a protruding wall block over it) causes all walls directly below it to also have a tall center post. There is also a more efficient downward method that goes (in downward order) observer, solid block, redstone dust, solid block, hopper/dropper. Any of these can go horizontally or downward as well. The blocks can be removed to make a wire that is slower but does not power anything next to itself. Each observer powers the dropper/hopper above it through the solid block, which changes its block state, activating the observer above it. A more advanced observer wire can be made by alternating, in upward order, observers, solid blocks, and either hoppers (only in Java Edition) or Droppers (in any edition). Each observer carries block updates to the next observer up or down. Observers can also be used to create a vertical ladder. Additionally, the first torch can be moved to the middle replacing the top slab and the torch with redstone wire, and adding another top slab before the second torch, which adds one block of height (as seen in the picture).

If using only one slime block per piston, an upward piston tower turns into a block update detector. Ĭombined Upward Ladder – Up Only 1×3×N 1-wide, silent circuit delay: 2 tick per 17 vertical block A vertical transmission circuit can be made by combining both torch tower and redstone ladder, resulting in a ladder with maximum height and minimum delay, as seen in the schematic. A simple piston tower can't transmit signals up because effects of quasi-connectivity cause the tower to freeze in its state and not disable upon falling edge. If using more than two slime blocks per piston, the piston tower can transmit a signal upward. Up to 11 slime blocks per piston can be used. Using slime blocks together with a basic piston tower may drastically improve its performance, because less pistons are used for the same height in comparison to a simple piston tower, and piston moves more blocks. Up or down 1×1×N 1-wide circuit delay: 1.5 ticks per piston (rising edge) and none (falling edge) This is a variation of the simple piston tower that uses slime blocks. An upward-directed transmission using pistons is not possible in Java Edition due to effects of quasi-connectivity, unless slime blocks are used to move the blocks of redstone. This makes piston towers less useful for rapidly changing states. Because of the difference in rising and falling edge behavior, off-pulses are extended by 1.5 ticks per piston and on-pulses are shortened by 1.5 ticks per piston and may possibly be erased altogether. another sticky piston placed underneath that solid block, pointing downward, then another redstone block, a space, redstone dust on a solid block, and so on, allowing 1×1 downward transmission. Piston tower Down Only, Up or Down 1×1×N 1-wide circuit delay: 1.5 ticks per 5 vertical blocks (rising edge) and none (falling edge) A sticky piston pointing downward can push a block of redstone into the space above redstone dust that is placed on top of a solid block. Torch cascade Down Only 1×2×N 1-wide, silent circuit delay: 1 tick per 2 vertical blocks Torch ladders are 1×2 tileable upward but 2×2 alternating tileable downward. Torch ladder Up Only 1×2×N 1-wide, silent circuit delay: 1 tick per vertical block Redstone torches can power redstone dust beneath them, allowing transmission downward. Up only 1×1×N 1-wide, silent circuit delay: 1 tick per 2 vertical blocks Redstone torches can power blocks above them, allowing transmission upward.
