I like the how redstone allows me to build and physically see circuits that normally are only shown on schematics.
I have made a 4-bit ALU with add/subtract and all the basic binary logic gates. The ALU also gets its input though a small registry that was shown to me by another builder. The RCA design was from a tutorial by The Redstone Programmer on YouTube. Artefox showed me how to make all of the other operations with !a, !b, or, carry, and flood carry.
What does the thing do?: It can save two 4-bit numbers and then perform either addition, subtraction, or any simple binary logic.

What do you plan on making for your build trial?: The same 4-bit ALU with a different registry design.
Do you agree with the rules?: Yes.
