What is your favorite thing about redstone: application of logic and physical manifestations of patterns found in algorithms

What's a thing you have made which demonstrates redstone knowledge?: An 8-bit ALU, A 4-bit ALU with PROM and a few extra functions like C registers, A, B comparator all that good stuff, serial bussing, and I recently started learning CLE adders

What does the thing do?: A lot!

Do you agree with the rules?: yes

I would like to see pictures, and a more in depth explanation of how your ALU's work. If you're learning CLE adders, you're probably good enough, but just be sure to include explanations and documentation IN your application.
(P.s. You don't need an account for imgur, so it's not gonna be difficult to upload there.)

So im going to assume that knowledge of an adder is basic and go up from there, First off you have (in this case 4) adders hooked together shifting left to create the ALU (Arithmetic Logic Unit) I first created the selectable inverters, which is just a set of vertical Xor Gates, then I created the carry cut by taking a block and sticking it above the b inputs with redstone dust placed on it this disables the torch that would normally create the carry two blocks above that is a redstone torch hooked to a line of redstone that controls the carry cut next I made the or function the way I did that was two blocks above the central torch in the first set of xor gates I placed another torch which disables the and gate and the carry allowing for both A and B to pass through one bit without creating a carry or being canceled by the and gate, next I made the flood carry for this I placed a redstone torch above the carry lines and attached them to the control wire for flood carry, next I created Cin by adding a block a torch and a lever.

And that's just the ALU, but I think that is sufficient info for an application

Ok, That looks good. I'll approve you for a trial.
