Building a Better Redstone Computer Tutorial 3: Basic ALU

[@steelejr]

To anyone following along in modern day, note that there was a small chanage in how redstone worked when climbig blocks and this current setup for the flood carry will not work past 1.15. The left-hand comparator for the input XORs outputs a power of 1 in front of it when flood carry is active and because the redstone climbs the blocks in front and to the left of it, a repeater will see the block as powered even though the dust on top of it is at 0.

[@ArmyMenMajor]

Do you know a way to fix it?

[@avimittal4748]

I attempted my own ALU based on your CCA adder and got a working 6-tick ALU, like yours looks like it will be. However, it is MUCH bigger and decidedly more unwieldy . I do like the ways these functions are implemented - especially powering the torch for flood carry with a specific signal strength - and I'm inspired to use these later. I did my 3-input-the-same functions by taking a NOR and ORing it in later, but this OR-only method is far superior. I love the videos! Specs of my ALU if anyone is interested: Dimensions: 18L x 11W x 18H Speed: 6 ticks Functions: addition, subtraction, any logic gate with 2 inputs where 2 or 3 inputs are the same (including the never-used ones) Inputs: Invert A, Invert B, NOR, Carry-In, Cancel Carry, Flood Carry

This is awesome that you have started a new tutorial series again! I've missed your channel for so long and I was so happy to see you making videos again, but I wasn't expecting a brand new computer tutorial series, so Thank you so much!

[@ХристоАврамов-б4п]

Hey bennyscube, I just came across your channel and I love redstone complex systems in minecraft. I wonder if it is possible to learn basic computer architecture by watching your videos and apply it into real world electronics. Hope you advise me how to complete my goal. Thanks.

Great Work Beni, I hope you come back soon, also for those of you in 1.16 this will not work do to some minor changes to redstone :(

It works perfectly in mcpe now! I'm building it

Hot fix for 1.16 java: Replace the blocks with the torches on them with target blocks. Put a comparator in subtraction mode next to the dust facing into the target block. Behind that comparator, make your slab ladder. Put a comparator facing into the comparator you previously placed. Make sure the signal strength of piece of dust is 1. This still fits in the same footprint, though it uses a comparator for each module instead of using 1 for 2 modules.

What doesn’t work in 1.16? It’s working for me

[@thomasliang1677]

Benny have you seen Nikkeru_'s new hex memory. Quoting Mat here "I can't believe she wiped the floor with me and Benny". You should check it out.

[@Vermillionns]

I think you should put lanterns on the input as you did for the output, things would be clearer,

[@kellangaming1108]

I'mma make this soon.

[@theorphanobliterator]

Also, after i got it working correctly, my output was exactly the opposite of that showed in the video. when all the torches were off, the output was all off except the bottom one!

yea benny i love alus

[@sp000ph]

How to get that shulker box with the furnaces?

[@dwhitaker86]

If you are on the ORE server, they are at Spawn. You can walk up to them and CTRL + Click the Scroll Wheel

[@CoDplayer458458]

Anyone figure out how much to use in each furnace if not on the ore server?

[@roxashikari3725]

It's on the comparator wiki page: minecraft.gamepedia.com/Redstone_Comparator#Containers

[@DantevanGemert]

How did you make the upside-down slab block?

[@samuelhulme8347]

Dante van Gemert just place a slab whilst looking at the top of a block not the bottom and that is basic Minecraft knowledge

[@okyloky9432]

@@juaneastley-fernandez9621 I'm pretty sure they were referring to the NBT edited top half slab that benny was using, which is not common knowledge. I hope either one of you read this and feel like idiots :)

[@theorphanobliterator]

I literally think this is broken now. I have exactly the right power coming out of the flood comparators, and it's not working. I tried tweaking the number of items inside the hoppers to see if it was right, but one item, the xor gate was on that i wanted off, and the other, it wasn't enough to reach the torch. Wtf?

[@petrinurmi2078]

Yea. 1.16+ java edition changed the mechanics somewhat and borked this design. It can be adjusted to work tho. The readon why this as shown doesent work is that 1st xor gate(2comparators) outputs rs signal strenght 1 infont of them. And due to mechanic changes this powers weakly the block on the left side and powers the repeater. I'll make video later describing this and one solution to this. Altho that solution makes ALU wider.

[@theorphanobliterator]

@@petrinurmi2078 that's no problem. I'll probably watch it lol, it's so hard to find new redstone computing vids nowadays

[@petrinurmi2078]

@@theorphanobliterator If you look comments to this video and sort by newest. There is a solution to this problem in Zumas comment by one user, that is almost identical to my solution. And uses same footprint. With my solution footprint is bigger and makes accumulator path take 1 tick longer due to 1 repeater more(signal strenght issue). But my proposal keeps this bennys cube thing intact, because this currently acts as a AND gate logic. I'll propably get to make video of this in 9h or so. Once I get of from work.
