Your favorite thing about redstone:I think it’s great that, unlike electrical circuits, redstone makes it visually intuitive to see where the signal is flowing.
A build you have made which demonstrates redstone knowledge (This is your trial build):Adding calculator
Explain what your build does in detail:All entered values are handled as signal strengths. The calculation uses the subtraction mode of the comparator, and the circuit is designed so that different circuits operate when the sum is 9 or less and when it is 10 or more. It may be obvious, but a 7-segment display is also provided, making it easy to read. Since a carry-over processing circuit is included, it is expandable.

Generally we want something around the level of an ALU, which can perform addition, subtraction, and various bitwise operations. An adder on its own wouldn’t be sufficient even with a display. Please reply with an update to the build whenever you can.
That calculator performs calculations based on signal strength, so implementing operations at the bit level is difficult.
So, I redesigned the circuit as a binary ALU. It is a 4-bit ALU capable of addition, subtraction, increment, decrement, XOR, XNOR, NOT, and logical right shift. This ALU is based on the CCA, with arithmetic functions added.
As you can see from the image, I created it right next to the circuit I posted first.
Forgot to mention: By using addition, logical left shifts are also possible. There are small constraints, such as entering NOT only in input B when in decrement mode.
OR, NOR, AND, and NAND cannot be executed at the same time. I think it would be necessary to execute them multiple times if used as a CPU’s ALU. However, I’ve heard that having separate circuits for each operation is not ideal, so implementing all operations based on CCA seems very difficult (though I guess it also depends on how much of the CCA components need to be used).
Added functionality. It now supports addition (logical left shift), subtraction (two’s complement), increment, decrement (NOT), OR, NOR, XOR, XNOR, AND, NAND, and logical right shift. In the circuit added below, operations are specified in binary, and a decoding process converts them to ALU control wiring. There is a carry flag, and I believe zero flag or odd flag can be easily implemented as well. If there are still missing functions, please let me know what features should be added. I haven’t made such a feature-rich ALU recently, so it might have become quite large. Also, it is currently 4-bit, but it can easily be expanded to 8-bit.
Yay, your application has been accepted! Whenever both you and a staff member are free, feel free to ask them for a trial. You are able to try again after failing and waiting 24 hours with a maximun of 2 trials / 7 Days. It is always recommended to do a practice trial with another member before starting your real one.
Note: Im usually available from 14:00-19:00 CET ingame.
