2. the thing that interest me in redstone is how similar it is to proggraming.
3.I selected to build an ALU for my application
4. ALU stands for Arithmetic Logic Unit. It can do addition in binary as long with all of the logic gates. It is a key component in making CPUs.
5. Previous ALU http://marcoscarballal.imgur.com/all/ hope that works.

After you showed me your plot on the school server, I would like to see you explain a bit about how the ALU works, since it is a very generic design.

Explanation of my ALU.(with modifications from niceboi88)
well i first made a 2 bit adder. an adder is composed of xors. since xors have the same out put for 2 true inputs and 2 false inputs, u have to have a carry. (because 1+1=10 in binary). u can make the carry from the first set of xors go into the second set as a 3rd input. u do this for however many bits u want your adder to be. since an ALU is supposed to be able to also do the logic gates and be an adder, i built it off of an adder. i figured the easiest gate to do would be xor because an adder is made of xors. all i had to do was get rid of the carry. i decided to place pistons so when powered by the "kill carry switch" they would push a block in the path of the redstone "carry" line. i then figured that the next easiest one to do would be an or because the or in the xor is very easy to find. i just had to change it from an adder to an or with the redstone torches. but then i realized that i didnt have to find every single gate in the ader. i knew from my logic gates that almost any gate could be created b inversing the inputs. for example, if i wanted an and gate i could just inverse both the inputs. so i changed my design in order to inverse all of the as or all of the b,s at a flick of the switch. also, to get the nand gates and such i added an inverse output at the end. It did get kind of messy because of my terrible bussing techniques but niceboi helped me clean it up, big thx to him

Although you made a few mistakes in your explanation (one of them being you got AND and NAND mixed up) I'm going to let you go on to a trial, good luck

yay! thank you!
