What do you like the most about redstone?:
I’ve always enjoyed redstone, from back over 10 years ago watching MumboJumbo, 7 years ago buying Minecraft and now with all kinds of cool computational redstone I’ve been practicing over the years, leading me to this server. I am going to study programming and take a lot of interest in languages like Assembly, so my end goal is learning to build a computer that I can code my own small programs in using Minecraft.
What’s a thing you have made which demonstrates redstone knowledge?:
I’m going to give two entries here:
my first real computational build back in 2019, which was a 4-bit multiplier with 7-segment display. (so dec > bin, calculate, bin > dec, display)
My more recent build that caused me to join the server was my 64byte RAM with vertical address decoding, to which I added compact controls and the Vertical Decoder myself.
What does the thing do?:
The 4-bit multiplicator that simply used a button and comparators to choose a decimal signal using signal strength, encode that into binary. Then multiplying those two Nibbles (4-bit Bytes) using a classic multiplication circuit built from 3 4-bit adders (that were very large and inefficient might i add). Decoding back into decimal using a horizontal design and feeding it into a (fairly compact) 7-segment display.
The recent RAM is very much inspired by the YouTuber I mentioned and repeater locking to store 8-bit values using a vertical design. This is done with simple glass towers and some comparator subtraction to invert signals as well. Loading is done by comparator subtraction glass towers as well.
I use AND gates so that only ADDRESS SELECTION + STORE/LOAD gives a STORE/LOAD signal to the RAM, I will skip the address decoder since that is just a very simple vertical binary decoder.

What do you plan on making for your build trial?:
I plan to make a 7-tick synced (8-bit) Cancel Carry Adder ALU, it will have XOR->OR control, A and B inversion, CIN control, Disable Cancel Carry, and inherently Flood Carry by combining CIN and Disable CC. The design is a modified version of the original CCA posted on the MyBB forums in 2014 that adds 2 ticks by using XORs to have inversion control over A and B. This design I recently learned from vieneky who has been wonderful in my steps towards learning efficient binary multiplication, thanks vieneky!
Do you agree with the rules?:
Absolutely, those sound like good rules to have in place!
[Edit: I credited the wrong person for the CCA design oops, Coolcat7023 is also wonderful though]
