Age (Optional):

Why are you interested in joining this server?: 
Id like to join this server because I want to get into redstone/tntcannons. I tryed to before with youtube it doesnt go really well because they just teach me how to build it and not like what does what you know? So id like someone in here to help me to get more advanced.
Current Redstone knowledge: 
My current limits are like 2x2 piston doors and some simple tnt cannons. I can also use repeaters/compareters. Im not that great with pistons/sticky pistons. So I would like you guys to help me get advanced with them so I can help others. One other thing is redstone torches I am horrible with them soo id like you guys to teach me how to use them. Same thing with observers.
Past Redstone Experience: 
I think my best creation would be a tnt sniper cannon it used multiple layers of slabs/redstone and repeaters and compareters. I can also make a basic sand cannon. I think how the tnt sniper works is because the tnt gets smacked against the top of the machine so it wont go straight up.
About how often do you play Minecraft?: 
1-5 hours per day
Application status: 
Approved
What kind of creations would you like to build on this server?:
