As a computer engineer, i appreciate all of the work you do to explain basic circuits such as in your second channel and even this push to explain discrete computer logic in ways more people can understand and enjoy. Wonderful work!

[@skyfeather3693]

You are so underrated. Managing to explain logic gates to someone who didn't even know they existed before watching this video, as well as making it interesting, is really impressive. I'm so glad I found your channel.

[@smarty265]

its a main part and in every build with some complexity

[@Qrani]

I think the logic gate explanation was good, but I don't think it specifically does justice for XOR gates, the way he explained it was that is only one of the inputs is on, then the output will be on, when in reality, it's if there's an odd number of inputs that are on, then the output will be one.

[@fyrewire]

as someone also building a computer in scrap mechanic, if you want permanant data storage (logic bits are reset upon lifting it") you can use vacuum pumps connected to chests of cardboard and spudguns (which break and place the cardboard) to make liftable storage

[@user-ss6gp2gu6r]

I think he will use logic gates for everything, including data storage, making it more realistic

[@orangespuddy7118]

I’d hadn’t thought about this, mostly because I hadn’t messed around with computer stuff when vacuum pumps existed, but that would be a good way to create and edit programs as it would be cool to allow players to share them

[@orangespuddy7118]

@@user-ss6gp2gu6r I think that what they are suggesting is very realistic as logic gates in real life don’t work without power, so you have to write that on something outside of logic, also it would allow players to share programs which would be cool for him to see community members using his computer and creating cool stuff

[@sayhellotoyou9271]

you could. However this mode of datastorage is not very dense.

[@fyrewire]

@@sayhellotoyou9271 while it is not dense, it is rewritable and permanant. if done in a cube of cardboard you can have a moving head

The real question is, can you make a computer inside a computer in Scrap Mechanic?

[@ReidCaptain]

😳

[@rf_fazlir3551]

No it impossible you cannot making a game inside a game that not a game about making a game inside the game.

[@ReidCaptain]

Now that's a good question

[@Artem4egg_]

There are things kind of looking like Os in stirmworjs, that basically does only programmed things like radars cameras etc

[@peterjadczyk1546]

Please keep making this series. I tried to do the same thing (in Vanilla SM) however got stuck at the program counter. I'm excited to see how you solve it. Also your teaching style is very friendly and straight forward.

[@bobsquaredme]

I just discovered your channel a few days ago and have been binging since. I love these types of games (Besiege especially), and love what you do with them

[@smarty265]

If you didnt know there is a Creative update around the corner bringing alot of the stuff exclusive to survival right now into creative mode its been in the test branch for a few weeks and its gotten alot of updates so its almost ready to put in main branch. It brings stuff like Water, Enemys, Chests pumps and more.

[@astronomicalgamer205]

I'm glad that you got some sort of a shout out from a more popular KZbinr. You are a amazing and hope your channel grows. Also if you can, going into the test branch makes the logic gates easier to explain as it has diagrams and stuff

[@jeezuhskriste5759]

Here’s a simplistic way you can think about inverting 2 input logic gates: By inverting the output, you just invert the entire output. By inverting the inputs, only the and/nor part is inverted, while the xor part is not. That is because 2 positives becomes 2 negatives and vice versa, but a positive and a negative just swap places, giving you the same xor output - everything stays the same, or everything stays different. Inverting one input is like a 90 degree rotation. The 2 xors - 10 + 01 become and + nor, while and + nor become the xors.

[@pastasketti]

finally someone who explains what each type of logic does maybe at the end of this series i can add some complicated logic to my builds

[@wolfaviator01]

I’m so glad you are doing scrap mechanic It’s like poly bridge except 3D, logic, fun.

[@kaiser1794]

This is the boolean explaination i've been searching for. This is a topic i've struggled to wrap my head around. Its easy to think about conceptually but converting the theoretical into application is quite difficult. Despite my googline efforts, i've never found a tutorial or video that explains it nearly as well as you have here. Thankfully i'm already subscribed to you cause your videos are amazing. The amount of time you spent editing this must have been enormous. Your work is greatly appreciated.

[@duncathan_salt]

Looking forward to this series! I'm currently working on building a computer in Cave Story using only its scripting language - it has some very interesting limitations to work within. It's very fun to follow along with similar projects! Best of luck - you clearly know what you're doing, but we both know that doesn't mean you don't need luck, lol

[@huntabadday2663]

I have been doing SM computers for a couple of years now and I like seeing that it is expanding to other channels!

[@Hlebuw3k]

The XOR gate will turn on if an odd number of inputs are active. N-gates just give inverted signal of normal gates. Each gate has a delay of 1 tick before it receives/sends a signal - 1 smallest logic step. Same for timers, even if you set its delay to 0 ticks. To make a simple consistent memory switch, connect 3 XOR gates in a loop, and activate all 3 at the same time for 1 tick.

[@gymzaal4412]

I would definitely recommend number logic in the future it makes everything so much simpler and makes much more possible

[@drcgaming4195]

truth tables?

[@srb9767]

For anyone interested in building a cpu and other logic related things check out a game called logic world. It’s on steam but not quite out yet. Hopefully soon. So long as you have a relatively good computer you should be able to run the cpu that you build much faster than in basically any other game that I know of.

[@sporewooky]

If you go into the beta version you will get more information on the logic. The logic gates will show what the logic means down at the bottom making it easier to understand in the next episodes

[@guiii0696]

This is the first time I pay attention on someone explaining gates

You can paint every block in the game, including lights, I suggest using this to organize specific functions that are made up form a lot of stuff to prevent confusion

[@ReidCaptain]

Good idea, I'll try to use paint to show the different parts of the computer

[@mtndew314]

This is one of the best logic explanations I've seen in a long time.

[@NStripleseven]

There’s a lot of potential in this, seeing as it’s kinda built to do stuff like this easily.

[@Egerit100]

Play Trailmakers Also I suggested u build a computer last episode of scrap Mechanic did u actually see that or is this just a coincidence?

[@sarchdesigns2884]

[@TheFrenchPlayer]

Scrap Mechanic can be really simple.. But really REALLY complicated too

[@blueflame_sm_yt]

If you want some added performance for your computer parts, I can hook you up with a link to the beta version of my new modpack. It doesn't contain much yet, but the only block it does have is a logic gate with 0 tick delay. Speeds up a sequence of full adders by a lot (as in, 4 bits normally takes like 16 ticks... now only 1). If you're interested, just find me in kAN / ScrapMan / Scrap Mechanic / SMM discord.

[@cubedude8690]

You can also make an inverter with the NOR gate.

[@xcreeperbombx61]

The NOR can act like an inverter the same way a NAND gate can. In fact, I prefer NOR over NAND when making a NOT gate because it acts to any signal. However, there may be reasons for NAND over NOR, I haven't gotten to experience Scrap Mechanic because my computer can't support it.

[@miltonfrey7274]

oh yeah, would love to see the rest of this

[@muhammadsyamilmohdsuhaimi5439]

I learnt this on physic and your explanation is good. And the fact that you can explain it on visual in a creative way make it better. I am good at math so the boelean's expression help me. Maybe you could make a side note on the left/right corner of the vid. So people can see the comparison. This is where the boelean's expression come handy to compare them. But that requires you to explain it, just suggesting tho

[@stuchly1]

[@jesterfrickinly8915]

I think you should use a chart to describe the functions of each logic gate, like having all 4 combinations of switch states, what state the output will be in with each type of gate. This could help us grasp whats happening without it being too convoluted.

I was considering getting into truth tables, but scrapped it in favor of covering it in a later video

hey im just wondering are you going to be making electronic storage? i know that a lot of logic gate simulations cannot simulate some components such as a j-k flipflop (or any derivatives such as t-flip flop) without hacky workarounds because of how electricity works. if you can make whatever in scrap mechanic, get back to me because i really wanna play around with a logic playground.

[@TheDancingH]

Lemme clear something up It doesn't matter which direction you connect things. You can drag a light to a switch and the game will know which is this input and which is the output.

[@ReidCaptain]

Well yeah, but logic gates are directional, so I wanted to show that you drag from the input to the source

[@maddog5944]

If it would help at all I've made a few calculators in scrap mechanic and some storage I have a 10 bit multiplier 81 but storage adders are easy so if you need a specific size I wouldn't mind making one and I have all the individual parts to these builds on my steam workshop also you can make two state storage using pistons and sensors (set to switch mode) it is way easier and more stable but it is much laggier other two state storage systems using only logic gates are complicated and unstable but produce almost no lag

[@chrisakaschulbus4903]

i remember when learning for my it job in school where my teacher was telling me that you can't make gates out of inverters just because his circuit program wouldn't let you connect multiple inputs to one inverter. then someone was downplaying my question with some comment about "minecraft and redstone being dumb"... i was so confused and disappointed.

[@etheraelespeon1986]

Man, I miss the old SM ui lol. It used to have little 2-input truth table graphics for each gate. Edit (April 2, 2021): it appears the graphics were actually reintroduced since i last played, idk when, but i’m pretty sure it was recently
