In Minecraft, a lot of stuff that you are able to make and use. One of them is an observer. Do you know what it is? It is a block and it will be able to radiate a redstone signal when the block or fluid that it faces experiences a change.
An observer is able to be mined. If you want to mine it, you will need a pickaxe. What happens if we mine an observer without a pickaxe? It will drop nothing. Besides mining it, you are also able to craft it. How to do that? If you want to craft an observer, the materials that you need are 6 cobblestones, 2 redstone dusts and 1 nether quartz.
In Minecraft Java Edition, an observer can detect changes in its block states of the target or the breaking or putting of a block. What does it mean? It means that changes like the age of crops will be able to be detected by an observer. It is because they are part of the block states.
What about in Minecraft Bedrock Edition? In this edition, an observer will be used as a block update detector. Also, it can detect anything which can cause a block update in that edition.
Now, how about the observer pulse extender? From the search that we did, a pulse extender can be used to increase the length of short pulses. In Minecraft, the most pulse generators consist of an input and a pulse limiter. You are able to add a pulse extender to generate a longer pulse including on your observer.
As explained above that a pulse extender is used to increase the duration of a pulse. And here are the most compact options.
- Repeater. It is up to 4 ticks.
- Repeater-Line Pulse Extender. It is up to 4 ticks per repeater.
- Dropper-Latch Pulse Extender or Hopper-Clock Pulse Extender. It is 1 second to 4 minutes.
- MHDC Pulse Extender. It is 5 minutes to 81 hours.
