Application for Zaloger

In-game name: 
Why are you interested in joining this server?: 
well, I would like to join since I want to learn more about redstone, because my knowledge is quite basic. I have seen that in this server there are many colossal and giant builds, so I thought that maybe I can learn something from these builds (in case I wrote something wrong, I'm sorry, I'm Spanish)
Current Redstone knowledge: 
As I said before I don't know much, at best I know something about observers, although I still don't understand why this gives two redstone signals when a block is placed or updated, I only know how to detect objects in one chest or another with a comparator, like making small 2x2 doors and some use of flying machines out of honey and slime blocks
Past Redstone Experience: 
What I will achieve, which is my achievement in redstone, is to build a self-healing ''prison'' using stone, creating it with a generator with lava and water. When this is generated, a piston that is connected to a redstone clock causes it to push the stone up. This system is done to the side so that when they reach the limit of blocks that a piston can push, little by little it moves it in one direction, while the other system does too. When new rows are created and matched, they are pushed up into the matched block by a piston, this creates a wall that recomposes faster.
About how often do you play Minecraft?: 
1-5 hours per day
Application status: 
What kind of creations would you like to build on this server?: 
I would like to learn about pistons, comparators and observers, because I would like to make flying machines and piston doors
