6:38 you can use "blueprint editing" where you edit the blueprint file in order to hook those 2 together, or even hook a logic gate up to itself.

I'm really sorry but I don't think he's making more. I've gotten very suspicious and conducted a short lived search. I think he stopped making these computer videos because they didn't pull in the same amount of views as some other videos. If you don't believe me, compare the views of his computer vids against his past present vids. It's sad, it really is. I wish he'd make more of them but he hasn't made one in 2 months so I'm sad.

[@leonardsvoren5774]

I got so exited when I saw the notification, and I really like your project

[@slavkrit6802]

The D-trigger can be significantly reduced - from 7 gates to 4. You make a cycle of NOR-NOR-XOR gates, then connect AND **CONSIDERING THE SEQUENCE** to NOR (the one connected to XOR) and to XOR. After that, also **CONSIDERING THE SEQUENCE** we connect the button, or any other input to NOR (the one connected to NOR) and to AND. And lastly, connect the switch (toggle button) to AND and you're done! It is quite resistant to short signals, but like any other D-trigger, a single-tick signal “breaks” it, like any other D-trigger, since it somehow has a cycle.

my brain is too smooth for this lol. Btw reid, I think you'll really enjoy electricity in the game Rust, it's a cool system

[@danser_theplayer01]

It is absolutely necessary to use a fourth gate (AND) to stop noise, hook up both states to the AND and the output of that to the OR. That way when you spawn it or give too short of an input in it doesn't glitch out and blink forever. But maybe your way of connecting bonus OR works too.

[@Hadeks_Marow]

You should have brought up how what you just did was recreate the "switch" item that the game already has, except even more practical because the switch-state of the game asset cannot be altered by logic, only by user input, where as the latch can be done by user input or by logic. I found this detail really cool but not everyone might realize this. I look forward to seeing when we get into a logical "If Equal" stuff in comparing data values beyond boolean/1bit data values.

[@heinzgunthergans3663]

[@RRKS_TF]

A self-wired xor gate allows fast and small memory. On a 1-tick input it will flip the value that is stored and only takes up 1 block. To do this you need to edit a blueprint that only has 1 xor gate and modify the controller list for that specific object. You can add increment, decrement, set and reset inputs easily with just and, nand and nor gates.

The first gate is literally an rs nor latch, it's so cool to see redstone mechanisms in real life.

[@arktufamily9498]

its not a redstone mechanism its a logic circuit. redstone mechanisms use the theory of logic gates in minecraft, not the other way around dude. its also called an SR Latch

[@maxmcg292]

@@arktufamily9498 ik but i have learnt about the concepts for redstone and I and now see how they work as logic gates

[@valderon3692]

@@arktufamily9498 In redstone it has always been referred to an RS-NOR latch. You will find far more results using that term. It's one of the first things I learned in redstone.

[@absobel]

This, this is what I never knew I absolutely wanted. We did that in school but we never tackled storage or things like that

[@Green_Eclipse]

If you have ever made an RS latch in Minecraft then this is more familiar than it seems. Redstone Dust intersections (including powering blocks) are inherently the or gates and Redstone torches make not gates. Together, you get NOR gates that can be made into RS nor latches as indicated in the video.

[@ishikani]

Ok, now this is very cool.

[@UncoveredTruths]

consider a logic gate as an operator in the boolean algebra, which has foundations in first-order logic where P,Q,R are common place.

[@Roaxial]

I knew this all already but good vid never the none the however the less :)

[@OriginalAstroProjections]

pls continue this series i really want to know how to make a computer in scrap mechanic

[@thecodewarrior7925]

Love the video! I will say using red when highlighting both on and off signals in your visualization was a little confusing. It would probably be easier to follow if you used something like green and red depending on the state of the line you’re describing.

[@numero7mojeangering]

You can use self connected xor to create your memory with 3 logic gates. And it will also be spawn free of clocking.

[@ryensullivan7564]

Remember me from before? Asking you to build a computer in besige this is perfect thank you so much

[@sirplay8519]

if you connect 2 (nor gates) and an (or gate) in a circle and then conect the (nor gates) to an (and gate) and then this to the (or gate), you have a 4 block design which always starts in the same position

[@ryensullivan7564]

You are the best thank you

[@navidryanrouf441]

You should use a D flip-flop instead of a D latch. The difference is that the D flip-flop has the clock signal be activated only on the rising edge. The problem with the D latch is that when the clock signal is on, the data line can change multiple times and the new data will also be stored multiple times, whereas for the D flip-flop, the clock signal only sets/resets the data only on the rising edge of the clock, making it so that the data only stores once. Also what you built is not a D latch, but a Gated D latch.

[@NStripleseven]

It would be a simple change, all you’d have to do is add a rising edge monostable circuit to the clock inputs.

[@orangespuddy7118]

This type of stuff has always interested and intrigued me, but with nor latch memory things the lift sets all values to zero and it doesn’t randomly choose a state it just switches between true and false repeatedly, although I assume you already have something in place for this.

Judging based off of his content up until now it is just for creative. His channel isn't really about 'playing' games. It's more about teaching and sharing his problem solving skills in a fun way. There are plenty of channels out there for Scrap Mechanic lets plays.

[@zancloufer]

So you basically have flip-flops hooked up into some SRNORLatches for your memory? As someone who understands actual logic and wiring but never really looked into the nitty gritty of computer memory I kind of want more of this. More curious how you take 8, 16 or 64 bit memory and have usable inputs and outputs for it.
