I'll still remember when this video was called: *Sculk-sensors, quantum uncertainty, and Minecraft circuitry (let's make a calculator)* I like the word 'quantum', and it does fit.

After they made it so skulk sensors measure distance, I've been thinking to try making an ear off sorts, which uses multiple skulk sensors and measures their signal strength in order to pinpoint the direction and maybe even coordinates of a noise

Turns out there is a room-sized CPU in the UK called the "MegaProcessor" which does, in fact, have hundreds of tiny lights showing circuit activity! kzfaq.info/get/bejne/orSRbMWCt7axcmw.html (thanks to Daniel for sharing this).

It's really fitting how these share problems with modern processors, considering these are also kind of wave-based.

Now I can't help thinking they should make different colors of glass act like different power resistors. Depending on the color, they reduce the distance that sound travels in that direction. Edit: Just adding, they could also make the colors line up with real world resistor color bands, like the four band color code

7:50 what's neat is you're using sound waves and seeing the same problem that happens on the scale where particles are more like waves. quantum tunneling is a nightmare that shows up when the newtonian physics breaks down. it's like the signal teleports over the gap. MinutePhysics did a good video on it, but i'm not sure it mentioned CPUs.

You can use carpet mod bots to load the area

I think what you were talking about with the wrong input leaking thorugh a logic gate is related to quantum tunneling, the transistors get so small that the probability distribution of the individual electrons goes beyond the insulator and sort of exists on the output side.

This reminds me of Wireworld, a cellular automata that behaves very similarly to these wires and diodes. Someone built a functional computer in it. It's gorgeous.

Nice! I imagine there's room for improvement in the gate department - you could definitely make an XOR gate by using horizontal two-state signal clogs across two lines, and that'd probably get the gate delay down.

The chunk unloading breaking vibrations should be fixed in the latest snapshot, would love you to give it a shot now :)

I've only seen one other person so excited to explain their circuit design. You really sound proud of your work in this video, for some reason. Really nice chill vibes

I'm happy you finally have enough time to share all of your projects.

I had always been wondering how would the new skulk sensor work with today’s red-stone computer, and it seems that skulk sensors can build a CPU by itself.

IIRC, it is in fact quantum tunneling of electrons that electronics designers are starting to run into with making smaller circuitry

Its fun how the signals can have a cross-roads on a single layer. For redstone or wires, you need to bridge one line over the other to not touch.

As someone who like Minecraft *and* Turing Completeness... I love this! 🤩 It also looks very clean, compared to some more messy redstone contraptions I have seen! (Also: have you tried the /forceload command to make sure the entire circuit stays loaded no matter how far you are?)

This was a fun video, thanks for sharing your build! You did a great job of explaining basic circuit operations as well.

Great video! Also, vibing with the bg music.

"a full-adder is like the utah teapot of circuitry" you're totally right and i agree entirely and also that's the most computer nerd sentence i've ever heard and it's not even necessarily that obscure

This is so cool, both on a technical level and visually! I'm always so impressed to see what people do with Minecraft mechanics :)!

i love your videos so much, i never really "get" them but theyre so sick no matter what

this is beautiful. the 8 looping noteblocks really sells it

There's a command that you can use that will keep chunks loaded within a certain area you set. Pretty useful for all kinds of things.

Found this channel through your floor videos, which aren't the type of content I usually watch but I'm so glad youtube suggested them to me cause you did a really good job with them which inspired me to check out the rest of your channel, and i've really enjoyed every video of yours i've seen so far.

This is an amazing way to visualize and learn skulk

I love the skul sensors they are memerising to watch, I hope we see many many "living" or "breathing" circuts and mechiens etc.

Just watched 'Why Lightbulbs Might be The Best Invenction Ever" by Veritasium discussing how real diodes were innovated into gates and the first computers to see this! Quite a treat. Well done!

wow... bravo on this. The work itself is incredible, and the narration and editing made this surprisingly easy to follow. I started out thinking I'd probably skip over the vid if it was out of my depth but that feeling never came.

using a childrens game to describe quantum tunneling, this guy is a genius

at 4:25 you refrence crosstalk and adress the issue with insulation. my brain , this is too good,. well played

I like to hear your thought processes, it is instructive actually

You should load up forge and install chicken chunks, chunk loader. It's able to prevent those type of unloading issues from happening. Cool video btw, pretty clever use of the game mechanics. Don't think I've ever seen anyone create full on logic circuits without a single piece of redstone!

With respect to the propagation delay for the 8 bit chained adder, it is possible to do any word length of full adder in just four gate delays, rather than the delay length increasing proportionally to the number of bits. It's a wild piece of math which swaps time for adding much more circuitry. Won't help with the unloading issue, though :P

to solve the distance problem with the circuits, why not make layers for each of the 8 copies, using a layer of wool between each to keep them separate? you'd still be following the core of the challenge as you'd be using only sensors, pistons, and wool, so by adding verticality you'd really just be increasing the amount of data you can have computing at once. Maybe if you compacted it this way you'd be able to add even more of them to add even larger numbers?

For the thing with the circuits breaking when you are out of render distance you could just force load the chunks

This is really cool! I donʼt have time to fully follow it at the moment and will have to watch again, but as for something you said in the beginning: have you heard of the Megaprocessor (thereʼs a Computerphile video about it) or the MOnSter 6502? Both are IRL functional (though slow and in the Megaprocessor case very nonstandard) CPUs that have lots of LEDs that indicate status and activity. The Megaprocessor in particular isnʼt hooked up to a display per se, just the RAM bank with a lot of LEDs . (EDIT: The Megaprocessor video was Computerphile not Tom Scott, but WhiteStoneJazz found it and itʼs in the pinned comment)

1:29 It is theoretically possible, because most silicon semi conductors all behave the same way. As in a transistor can be an LED or a photoelectric diode (or solar panel), an LED could be a transistor or a photoelectric diode, and a photoelectric diode (or solar panel) could be a transistor or an LED, so when you apply voltage to the gate of a transistor it might generate photon emissions in the most likely form of near-infrared, if we go off of 1.12 eV for the Si band-gap, however we don't see them because the cpu die itself is highly fragile so we protect it with a stronger heat spreader, as well as the usual shielding off the die itself.

awesome job really cool build and excellent explanation of the circuits/theory 10/10

This is so awesome!! I'm currently working toward an electrical engineering degree, and seeing the concepts I'm learning about show up in this video and actually being able to understand them was a really cool feeling.

This was right cool and I appreciate all the explanations as to how it's related to actual circuitry. Very interesting.

I just want you to know that this autoplayed immediately after Ben Eater's latest 6502 vid. That's extremely high praise from the algorithm imo

the flat world with skulk sensors kinda reminds me of the silicon wafers that real life circuits are essentially etched into with lasers

I love this! I want a world download so bad. Also, you can test with multiple clients to keep different parts of the map loaded. Maybe just invite a few friends (or afk bots) to station in different locations.

This is so cool! I don’t think I could’ve done anything nearly as cool as this! Wow:) I found your channel recently-ish, and you keep amazing me with these unique ideas

Sounds like you need to download a couple mods to keep those chunks loaded and redstone running so we can see this work in action! Looks pretty cool.

Even as someone who doesn’t know anything about coding, this was pretty clear to understand and so cool :)) great video!

While watching the video and the moment he mentions that the signal looks like electrons moving through a wire, an idea came to my mind. And it is that if you think about it, and with a little bit of imagination, the floor made of sculk sensors reminds me of the electromagnetic field and its ability to make light waves travel through it.

Wow. This is both awesome and a bit concerningly large for a 1-bit adder.

Really cool, I learned a lot! :D

Wow! That NOT gate is so cool! I never thought it was possible.

Just found your channel, such a cool vibe

You used an astable multivibrator as a memory cell. Congratulations, this was always possible but I have never seen an actual application for it. Impressive.

For a second I thought you made an actual quantum computer in Minecraft. I was shook. Doesn't sound that far off. I am aware that each qubit requires exponentially more RAM to simulate classically. Still a cool Idea tho.

Man im 22 years old I've been playing this game since I was 11 and I could never understand how crazy this was until recently. I'm studying mechanical engineering right now and have had to take a bunch of electrical courses as a bi-product. This guy is literally teaching electrical engineering but in Minecraft. Like holy crap man i hope you went to school for this,

"It would be cool to make CPU with a faint glow where circuit activity is" I know I'm fun at parties but real world CPUs (even fairly old ones) are way too fast and for the human eye it would be just the entire thing blinking or just glowing constantly Edit: More likely glow constantly because light bulbs (not all of them but for example LED-based ones among others) do blink but you don't see it. CPU clock speeds are a lot higher than the frequency those bulbs flicker at so I think that even accounting for not every piece of the circuit being used all the time, I think the whole thing would still appear constantly lit

The flatness makes it really easy to see what's going on, but I wonder how compact these could get if you utilized the 3rd dimension.

is it possible for the "wilres" to be sent up and down n the world to make the circuit smaller to allow for them all to be rendered?

really interesting video and great explanation!!

As someone who has never used sculks before, you forgot to mention that (And I may be wrong here) sculks power objects when they activate near them. At least I think, it looks like that's how they work in the video. I can't tell for certain.

ont thing that you could check out to get around the chunk loading issue is using something like the ftb utilities / teams mod(s). It might need some extra mods but with those atleast it will let you chunk load alot of the circuits and hopefully let you build some crazy big circuits

Fascinating! What a great video!

Checkout the simulation distance settings. That should be able to help you with the issue of circuits not rendering when you're far away

one thing i just thought of is that they should make skulk sensors use directional placement, like so it can be placed on the side of blocks aswell, idk if it would change any current functionality but would make some cool builds i think. Like telephone poles or something on a street.

I'm sure someone else has mentioned this before, but as for solving the chunks unloading, couldn't you do this on a multiplayer world and have other people stand throughout the circuitry to keep it loaded? for proof of concept, at least. There's gotta be other ways to keep chunks loaded, too 🤔

cant you stack multiple layers on top of each other to make them all inside one loaded area? would need a way to transmit signals up or down

When I make my redstone CPUs, I always make sure to add plenty of redstone lamps so that you can see all the activity!

1:05 Try maxing out your simulation distance, which would at least help with the larger builds, but it will still break if you leave that simulation distance.

You just need a bunch of players standing at different parts of the circuit to keep the chunks loaded. Or there's probably a way to do it with mods

So it looks like after the newest snapshot this thing won't break when unloading chunks, pretty cool

3:58 I dub thee, the "Screamer Gate"

The die limit for Minecraft is 4 Sculkmeters.

could you use verticality to compress the circuit enough that it wouldn't break from unloading?

Seems like a good use-case for nether portal chunk loaders

This thing heavily reminds me of the domino version of a full adder.

why is this so relaxing??? I just was blessed by the algorithm

Did someone comment that you can go in settings and change the "simulation distance" so that things will keep calculating and updating farther chunks away from you.

Now try calibrated skulk sensors

i wonder if its possable to make a pixel screen animation lin vanilla minecraft using this method without commandblocks

This guy has shaders and a sculk sensor world, his PC must be tired.

The sculk floor might translate to an elastic sheet medium and be build irl

I've been binging your math content and love it! This video is especially excellent. I wanted to point out though: You recited exactly 69 digits of pi at the end of this video. Nice.

I really like this guy and im excited for future videos

Amazing as always!

The issue with making a cpu that has glow wherever the activity is that you have to bog down operations with so many leds that it might impede normal functionality. I think the solution lies in changing your sight, not the machine itself. It may be possible to create a camera which can detect the magnetic flux created by the motion of electricity through the chip. Or I guess they probably glow slightly already, though that seems probably less energetic

If I remember correctly VanillaTweaks has a chunkloader datapack, which will keep any chunk that has a lodestone+netherstar permanently loaded. Perhaps that could be a solution to the unloading problems?

I think you would be interested in seeing the “visual 6502”, Google that phrase and it will come up. They took high resolution images of the 6502 and created a visual simulator.

I opened this video from my recs feed just to say a single thing: this looks like a ZOINKED ludo board. Holy shit. (very cool))

Could this be built in layers for each bit being added together. This would allow it to be built in a single chunk. Wool could be used to "insulate" the layers from each other, with holes in the wool layers to allow the signal to propegate where required.

A single mod can help with this, FTB CHUNKS. All it does is add a sub menu that force-loads chunks.

Stack the one bit adders vertically to stay within the same loaded area

There is something called simulation distance in the settings below the render chunk distance.

I hope you know I really appreciate your content :)

ShulkTech is actually really cool, I'm glad it was added to the game.

Is the editing new? Much less distractions and more cuts!

@whitestonejazz You already have carpet mod installed, invoke a player with /player name spawn

You could try using a chunk loader mod so the 8 bit adder doesn't break

Could you fix the unloading problem for the 8-bit adder by stacking these in some way? You might have to add a bit of actual redstone but I'm not sure.

It's alive!

How do the wires not just make infinite loops? Whenever I have a piston above a sculk sensor, it runs forever and can't be disabled without removing the piston.
