Application for Thelm76

In-game name: 
Why are you interested in joining this server? (MUST BE OVER 2 FULL LINES LONG!): 
Hi! I'm a french player and I wouldlike to join your server for a few reasons : I play minecraft since the beta 1.7.3 and I love this game! I have tried modding, building, command blocks, and my favorite : redstone. Today, I think my skills limited. Now, I want to learn more about some of the contraptions on this server to enrich my knowledge. Also, I thought the anglophone community more mature, more welcoming and more skilled than the francophone.   
Current Redstone knowledge (MUST BE OVER 2 FULL LINES LONG!): 
Today, I know globally all the mechanics of redstone, the basics of binary, and the main logic gates (AND, OR, NOT, and XOR). I think with that we can do anything with that, but my main lack is I'm too perfectionist : I'm often stuck because I want the compactest and fastest redstone system. One of my quality is I like to do systems by myself. So I can struggle for long time on the simplest systems to make my own "better system". That's a good way to learn but there are some limits (Really hard to learn how to build "computers" alone).   
Past Redstone Experience (MUST BE OVER 2 FULL LINES LONG!): 
I don't really remember all my systems, but recently (today) I've made my first binary adder (infinitely stackable) with XOR, AND and OR gates (some screenshots are in the links) I have also created a binary to decimal converter with 7-segments displays (A little bit bigger ^^') with two matrix of redstone torches (the first to isolate the different binary combinations and the other to convert this isolated signal into a figure on the display). Less in the server's mentality, I've made 5*6 doors with piston extenders and slimeblocks, a hidden nether portal with a secret passage behind with some observers, pistons extenders and logic gates, ... One of my favourite is a 4 blocks hidden stair that comes up out of the ground. Unfortunately the vertical quintuple extender isn't by me, but I've made a lot of redstone around, so I think it is fair to say that the system is made by me.   
About how often do you play Minecraft?: 
1-5 hours per day
Anything else you'd like to mention? (Optional): 
To begin, if I killed the English, I'm sorry ^^, it's not my mother tongue. On my computer I like to program, to do CAD, to hang around on youtube, and gaming!   
Application status: 
What kind of creations would you like to build on this server?: 
On your server, I wouldlike to learn about calculators, ALUs, CPUs, and many others systems that can be based on binary, but I can also try to build many other systems according to my ideas, like x-tuple piston extenders, x by x doors, etc. When I do something, I like to explore it in all its aspects, so I just wouldlike to build redstone in different ways!
