Sorry for the delay in content, I just needed a bit of a break. I'm hoping to have a video out once a week from now on but I may still miss here and there. My goal is to try to make some more involved projects that I've had on my backburner for a while, so there should be some good stuff on the way.

I can finally not have to open another tab to figure out what 2+2 is

Surprisingly this is actually a really elegant explanation of logic gates, I don’t know if that was the plan but well done.

Those are some of the strongest logic gates Ive ever seen

I was expecting nothing more than an adder. But we got an entire summation machine!

Nice. Now make a bridge in Microsoft word.

He is gonna be a successful redstone master if he try

hes gonna do quantam physics next in poly bridge 3 next, i know it

Came expecting just an adder circuit, but I'm genuinely impressed with the registers and bus. Kinda crazy this was possible without it blowing up or the game lagging to unplayableness

Now make it run DOOM.

It's interesting to see what your logic gate mechanisms look like. I don't know enough about mechanical linkages to say much on them in that context, but coming from an electrical engineering/programming background myself, I'd always wondered what sort of mechanisms would be involved in creating logic gates in polybridge.

I love how many random games are Turing complete

Achievement Unlocked: Turing Complete! Seriously tho, the whole video is impressiveness one after another. from bits to gates to adders to RAMs to programs to outputs. Inaccuracies are the bane of any mechanical computer yet you conquered it all. I especially love the "wheels on wheels" output method. It reminds me of those fourier transform video demonstration and how elegant it is mathematically. It's basically a branch of a binary tree! Visualized! Needless to say, you mechanical knowledge is incomparable

The great part about computer builds in sandbox games is that while they are limited by part count performance, simulated mechanical delay, or delay in the code, they can be built in basically any sandbox game with moving parts because logic gates themselves are simple.

I thought you were gonna use some sort of clockwork mechanism but this way is pretty cool too. Would love to see you make computers in different ways in different games too!

Wow, you make a computer in game where need create bridge?!

This is fantastic. You went way further with this than I thought was possible. I have shared this with everyone I know, amazing work.

Bravo! I’m taking a computer internals class and it’s always fascinating to see the different ways people can simulate or build logic gates

This should be useful for my exam in 13 minutes, thanks!

I love the error correction compliant mechanism. Like a mechanical amplifier!

Never would imagine that i would ever watch someone programming in a computer inside poly bridge, but fair enough, here i am fully enjoying it.

Hey reid.... this is a game about making bridges. this is a calculator. Your a legend.

Really cool! I really like studying and making these sort of computers, the good news is that there is a lot of content on KZfaq about it ( usagi electric comes to mind immediately). Glad to add this video to the group!

Great work! I'm always impressed by more mechanical implementations in games without an obvious logic system

Nice one, now make a fully functioning portal gun in beseige Good luck lol

Your implementation of a almost SR latch was pretty interesting. Hybridizing 2 input types was cool, along with the fact that it was effectively its own logic gate. The only downside is you _technically_ lose Q’, but it’s not often used, and can be simulated with a not gate anyway. Cool gate!

Amazing! I was expecting you to build an adder and call it a day, as many people do, but you actually built fully working, programmable computer!

For those who don’t know: - AND gates require both inputs to be active for it to make an output. Two 1s go in, 1 goes out. - OR gates only need one of the two inputs to be active for it to make an output. One 1 goes in, 1 goes out. - XOR, or exclusive OR, gates require one specific input for the output. It has two inputs, but it can only accept one at a time or else it doesn’t work at all. - NOT gate, commonly known as an inverter or inverse gate, turns the input into the opposite when outputting. It turns 1s into 0s and 0s into 1s

i honestly found myself understanding logic gates a lot more, thank you they've been so confusing haha

I tried to make a slightly larger calculator a year and a bit ago in pb2 - managed to get a seriously compact adder, but could never quite get the D-latches to do their job. Most likely because I "locked" them in place by actively tensioning a cable instead of passively using a spring. great work!

Hey! Love your content! You should try From the Depths, its a really fun sandbox building game that kind of fits in to the genre of games that you play. Its a block based building game where you build ships, tanks, planes, satellites, aircraft carriers, etc to fight ai craft and theres a campaign too. It would be really fun to watch you figure out the weird things you can do in the game

Thank you for such great content, this is awesome!

My brother and I have *joked* with each other in the past about you doing this, but we didn't expect it to actually happen! Incredibly impressive creation!

Wow that's really good. .. I kinda fell in love with computer engineering and went a little crazy and built a working computer in no man's sky. Using inverters and autoswitches as transistors. Would love to see what you would devlop with such a system

You are insane great vid, I built some logic gates and made an adder years back but it was only 2 full adders together xD

Ok, but can it run doom?

This will run doom for sure

Do you have like. Napkins or notebooks that you record things on while you're working? It'd be super cool to see all the little thoughts and records that you keep track of while doing this stuff.

I’m glad ya still make videos!

Ah yes, a $1.3M computer that can add up to 15

You are too smart for Polybridge😂.

We are making minecraft inside of minecraft, a roblox player inside of a roblox game, now a computer inside of poly bridge (a physical game engine), A COMPUTER WITH A GAME INSIDE OF TERRARIA, AI THAT CAN CREATE AN AI, WHAT FURTHER? ALTERNATIVE REALITY?

Just realised the similarity that nile red holds with your narration style. epic!

my mind was blown, subbed for the cool content

Not gonna lie once i lose track of wtf was happening, everything else after became impossible to comprehend. Like god damn Algebra II in highschool. Thanks for the nostalgia, loved the vid

This is awesome. And not only did you make a digital computer - it works in analog as well!

that's exactly what I wanted to try making once I got poly bridge and I wasn't sure if it was possible but HERE WE ARE!

I love the way that it's all jerky and physical, it brings me joy

I think that making a controllable plane might actually be possible if you find a way to control the weight distribution.

That's insane, mad respect.

Make a computer that runs poly bridge 3 in poly bridge 3. I know it wouldn't be possible but it'd be dang funny if it t'were

Finally another video, I love these

This is gonna be epic

next up: building complete von Neumann architecture in PB3

Not sure if it was suggested before, but I think it might be interesting to see you do a playthrough of Turing Complete? It's a game where you build an 8-bit computer from scratch with logic gates and write programs on it. Not sure if there is a sandbox mode in it though.

i think it would be relatively simple to make a 7 segment display. you could just use a bunch of and gates to convert the binary into decimal, and then run the output to a display

Nice! you really are a mastermind

Great video keep the great content up

OMG IS THIS AMAZING! That made my day!

you should try this in besieged. maybe working in 3d will be a bit easier, and you dont have to reinvent all the logic gates as most of the components available in poly bridge (springs, pistons, rope, etc) are already available

My digital systems professor would be impressed. Well done

What I expected: a full adder What I got: 😲

Amazing. Next vid: I made poly bridge 4 in Poly bridge 3.

Holy, you are just amazeing

I guess this means that polybridge is Turing Complete. I can't wait until we get polybridge made inside of polybridge!

I didn't understand it, but I'm impressed. Good job :)

super video

It's much more complicated than making computer in terraria, or minecraft... You're genius!

thats a nice logic gate you have there 7:35

It always feels magical to see logic gates being composed together to make a programmable computer. This is honestly a pretty good demonstration for how analog (non-electrical) computers are possible. It's great.

next time on "ReidCaptain": Hacking into pentagon using polybridge

LES GOOOOOOOOO BEST VIDEO ON THE CHANNEL SINCE UTTT !!!!!!!!!!!!!!!!!!!!!!

Awesome! Ploybridge in Polybridge when? :P

This gives a new meaning to bit flip errors.

amazing work

Honestly this video makes me want to know more about your education. Like the typical youtuber lore is “i dropped out of college for [insert major] to focus on youtube,” but this is a lot more complex than jacksepticeye’s marine biology fun facts.

He took it seriously and actually did it!

I understood almost nothing in this video but I loved every second.

amazing video!

impressive as hell ❤

In the word of RCE, very efficient design

i only understood any of his from Minecraft lol but it was a great video keep it up your doing great.

With just those gates you could program poly bridge given enough time (and frames). Prbably couldn't display it, but the code would be simulating it.

I think this is the most impressive thing that I have ever seen

This is the content I'm here for! 🗿👏

The most impressive thing I ever seen on ploy bridge

I scrolled past a video yesterday along the lines of "How bit flips actually physically happen". Now I know that somebody just miscalculated the stiffness of the many springs in my computer

Many of your logic gates look like very strong shapes! 😏

A part of me wonders what you do when not doing the most insane things on KZfaq. Probably solving all of the world’s engineering problems

Your speech mannerisms remind me a lot of nilered. Cool video.

Omg this is going to be interesting!

Wow, that’s incredible

Amazing :D

now he gonna make the poly bridge 4 in poly bridge 3.

7:40 you can definitely make xor w/ just nand, or, and/or and gates. Nand and nor gates allow for all circuits

Imagine being one of those cars in wanting to cross the River and then seeing a huge adder in the sky

I want say first that this was a really cool video, you make ridiculous things in polybridge, and it's a spectacle to see every time. So please believe me when I say I mean this in the nicest way possible: I don't know if you script your voiceovers, but please try to cut down on beginning sentences with "now", it's ok every now and then, but there's a jarring amount that's hard to unnotice, and it's hindering a great presentation the way "uh"s and "um"s do.

Finally someone saying "meters", I'm tired of hearing always "feets"!

*“Today I programmed a computer playing poly bridge in poly bridge”*

My first reaction: "You did what?"
