Contents AppearanceThe observer has a small red dot on the back. The sides are similar to a, but with a gray 'belt' on them. The front is decorated with a stone face.MechanicsThe observer has two sides: a detector side and an output side. The output side will create a one-redstone-tick (two game ticks, or 0.1 seconds) if the block at the detector side is updated or changed. For a more elaborate demonstration,.UsesThe observer can detect different stages of flowing water (the depth and position), the stages of growing grass or crops, and other observer blocks. Observers can be used to create cool lighting displays, vertical redstone signal transporters and clocks.

It does this by detecting the change in the target block's ID or data value. In other words, an observer emits a redstone signal when a nearby block has been updated.Crafting.

After testing for a while i created a great design for melon and pumpkin farming. This design is greatly stackable, has good collection rate, is very dense(one row of melons for every 3 horizontal lines, on both sides at once) the design is only 3 blocks thick with melons farmed on both sides, or 2 blocks thick if you farm one side. The two sided design has double the spawn rate while making the farm only 1 block thicker. The collection rate is over 90%, there is only a few melons that don't fall to the bottom.It's important to stack this on the z axis, since it uses rails that cannot lead to each others. You can easily make an automatic harvester at the bottom using water flows and hoppers leading to chests.
