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.
Not only that but he also encountered many problems that were similar to electronic counterparts (chaining gates breaking things, certain gates being more unstable than others, errors adding up etc)
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
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.
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!
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
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.
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!
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?
Really cool! I really like studying and making these sort of computers, the good news is that there is a lot of content on TH-cam about it ( usagi electric comes to mind immediately). Glad to add this video to the group!
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
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
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
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
There are actually ways to feed the bits directly into gates, but you need 3-5 gates (as far as I remember) for each of the 7 segments. If I remember that right, it would be 30-ish gates total. More gates than this whole computer currently has, even if you count each of the mechanical linkages in the output slider as an "analog addition" gate.
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
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 don’t know what any of the gates do, and this made no sense, I just like watching Reid Captain make things that weren’t meant to be created in Poly Bridge 3.
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.
It is a great demonstration for how digital computers work since they did in fact use digital logic here, analog computers are a bit different than just saying that it isn't electronic since we have analog electrical computers too.
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

No wonder theres been 3 weeks since the last video
One video a week seems insane for how hard these projects look.

This is too underated
Theoretically you can run doom in poly bridge yes but you would need a complicated display
This is fantastic. You went way further with this than I thought was possible. I have shared this with everyone I know, amazing work.
Right? He made an adder and I thought wow that's awesome, and then he just... kept going lol
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.
This should be useful for my exam in 13 minutes, thanks!
Hey reid.... this is a game about making bridges. this is a calculator. Your a legend.
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

I’m glad ya still make videos!
I think that making a controllable plane might actually be possible if you find a way to control the weight distribution.
you could probably pre-program the controls but i don't think poly bridge allows for live input unfortunately
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

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
I could maybe make a purpose built thing to do a very basic version of that

I love the way that it's all jerky and physical, it brings me joy
I guess this means that polybridge is Turing Complete. I can't wait until we get polybridge made inside of polybridge!
In the word of RCE, very efficient design
my mind was blown, subbed for the cool content
OMG IS THIS AMAZING! That made my day!

Amazing. Next vid: I made poly bridge 4 in Poly bridge 3.
He took it seriously and actually did it!
Finally someone saying "meters", I'm tired of hearing always "feets"!
My digital systems professor would be impressed. Well done
thats a nice logic gate you have there 7:35
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.
7:40 you can definitely make xor w/ just nand, or, and/or and gates. Nand and nor gates allow for all circuits
This gives a new meaning to bit flip errors.
That's insane, mad respect.
This is awesome. And not only did you make a digital computer - it works in analog as well!
Except for the memory, that's digital
