Have you read the Read Before Posting post?: I have.
Your favorite thing about redstone: I deeply appreciate Redstone’s simplicity. I think it’s quite beautiful in how it allows you to spatially reason about circuitry, which I find a fundamentally easier approach. I think it makes logic and circuitry fundamentally more accessible.
A build you have made which demonstrates redstone knowledge (This is your trial build): 8-bit RCA with bitwise logic operations and added flags.
Explain what your build does in detail: A first-principles based Ripple Carry Adder and subtractor with added bitwise logic operations. The adder has a mode for doing A-B subtraction, as well as doing bitwise operations. You can manually configure it to do B - A operations as well, by instruction it manually to do -A + B + Cin. Very standard stuff.
The following flags are implemented: Carry / Borrow Flag, Overflow Flag, Zero Flag, and Carry Out. These do not make sense in a vaccum, but are typically used for branching when the 'A’LU is used in a CPU with branching - and they were added with this in mind. Currently there is 1 known bug with the Overflow flag where it will not consistently trigger for operations making use of Cin. I do not intend on fixing this bug as I have moved on from this project.
The build is made entrily from first priniciples, which means that every logic gate, every operating mode, and so on, is made from scratch with as little outside influence as possible. Therefore it is not only big and bulky, but slow too. However, these were not design goals. Clarity, readability, and originality of design were. This is all my design, from start to finish, and I had to (much of which I later learned I re-) invent(-ed) all the work put into it. It was a very fun little challenge. A major goal of the build is to have it be easily understandable, and as such it is brightly colour-coded, and large parts of it is labeled and divided up to show the process of how it works and is constructed.

Do you agree with the rules?: I do.
Note: I have brain damage. Not as a joke, but as an actual diagnosis from work-related stress. Whatever the rule, I am going to use pen and paper for Two’s Complement translations. I am not willing to pay the price for doing it on the fly in my head. The arithmatic and algorithms are not a problem in themselves, it is keeping the process and the values in my head that is. If this accomodation disqualifies me from becoming builder, then that’s too bad, but it’s no big deal.
I was not planning on applying anytime soon had not the work with WoL required it. ALso: Don’s comments during Friday night about me being trialed, application or no, on “Saturday” (which is today for me) really pushed up the timeline.
