Application for CoolcatMC

In-game name: 
Why are you interested in joining this server?: 
I like doing redstone. I haven't been able to find any other servers that support doing redstone. I can help by trying to teach players who are new to redstone. I can also help by making redstone contraptions for the server.
Current Redstone knowledge: 
I can't build any piston door bigger than a 4x4. I can't make a piston extender past 4 blocks. I can make a 4x4 door and a quadruple piston extender (as stated earlier) I can also make a key reader.
Past Redstone Experience: 
I made a I also once made a flying bomber. it used bud powering pistons, slime, and redstone to fly, and sent tnt down with tnt dupers. I also made a 5x5 piston door, but have since forgotten the design. In my opinion, the best one overall is when I made A 7- segment display. I forgot the design for that one too, unfortunately.
About how often do you play Minecraft?: 
1-5 hours per day
Application status: 
Not approved
What kind of creations would you like to build on this server?: 
I would like to make hidden blocks, piston elevators, and piston doors.
