Binary to BCD | Logical Redstone #10 

Check out the NEW AND IMPROVED logical redstone series here! ru-vid.com/group/PL5LiOvrbVo8keeEWRZVaHfprU4zQTCsV4

God, years ago I remember trying to work out how binary to BCD worked like, in a "how does it ACTUALLY work" instead of "oh just trust it works" and nobody actually explained that part, the why, and I think I figured out why it had to work the way it did but I've since forgotten what I figured out. But I think you explaining the whole "shifting is multiplying by 2" explains it way better than how I figured it out in the past :o

If you don't like the tutorial design, make sure to check out the combinational design at 25:26 as well! I hope you enjoy the video!

when the man explains computer logic using minecraft and redstone better than actual youtube videos with real computers and coding. Like what the heck lol. great series

PLEASE READ THIS: Hey, I downloaded the world and I noticed the serial converter doesn't always work. When you type in a number from 144-149, it will work the first time, but then the lines will turn on and off repeatedly, making it so the next time you use the machine, it outputs the wrong number. Just thought I'd let you know in case you have a fix for that. I did find that making the yellow line turn on and then off stops the oscillation of the pulses. Btw, I downloaded it twice to make sure I didn't just accidentally break something. It always does this. Also, that converter is actually really genius and insane and took me a while to understand what was even happening lol. Love these videos!

Dang these algorithms are just straight up dark magic. Fantastic video series, haven't found anything else like it on RU-vid. Can't wait to see what comes out next. Super inspiring stuff!

i have been waiting for this vid

I couldn't for the life of me wrap my head around how binary is translated to bcd other than a decoder for every digit. Thank you so much, my redstone is gonna be a lot more fun with this knowledge!

A'ight bois, let's do some 256 lines encoders

This video was needed. I made a decoder with subtracting. I subtracted 100s, 10s and 1s from the highest possible as many times as possible and the shift to the next bit. Pretty damn slow. Like: 10111010-01100100=01010110. Not subtractable anymore, so subtracting 1010 as many times as possible, then subtract as many 1s as possible and input the amount of subtraction into the 7 segment. So in this case 1 times subtraction into the 3rd digit. 8 times into 2nd. 6 times into 1st=186

so in-depth and so easy to grab. Thank you for making these clips.

wow, you are fantastic at teaching this. Your builds are so impressive and complex, but you also know how to make these concepts very understandable! Your video on basic logic gates really helped me understand programming logic in a way I haven't thought of until then. Keep up the fantastic work ❤️

So what I’m hearing here is… there’s a much easier way of doing the thing I just spent like a week on… I wanted to challenge myself so I used your calculator tutorial to make a 3 digit display, with inputs and clearing and all. The challenge was that I wanted to send all the information from the input to the display along one redstone wire. And I spent so long on the receiving end trying to decode from the signal and encode back to binary, and then decode to the display which then encoded into the specific digits- just so much… when I coulda done this… Oh well, I’m happy with my puzzle solving. It was fun either way.

I never knew there was a serial binary to BCD. Only the combinational binary - BCD. Also, your design (If it is yours) looks a lot different than the spaghetti of spirals that the older ones had. Cool vid bud!

I really like how the series is progressing

I had already done a binary to BCD converter using double dabble in my world, but I never understood the algorithm rule before you explained it in your video. Thanks for the knowledge, great video as always !

these videos are absolute gold! i recently joined ORE and am continuing on my computational redstone journey because of you! (and the masterpiece that is the chungus 2 ofc)

i have been looking for this exact topic for ages! you explained it perfectly, love the series.

This series is really making me better at this sort of redstone, thank you.

This series is wonderful, I expect it to get a lot more people into redstone logic. Thank you.

Excellent video, excellent explanation, and I can't wait to see what comes next

The combination bcd has a special place in my heart as the first bin to bcd I ever made so I perfer the combination binary to bcd. nice video about minecraft binary to bcd

THAK YOU! Finally a Double-dabble tutorial that makes sense

Worked for my 9 bit calculator answer converter. Thanks!

I love this Series keep it up man!

I like this series so much

Thanks for the tutorial! I couldn't search any normal tutorial video that has normal Bin 2 bcd converter, and this is the only video that was exactly what I needed

man, i know im a little late but iswear i watched this video the very first hour it came out, and im revisiting it because i was about to implement that circuit into the 9 bit binary output of my calculator project, and i am so greatful that i found how to convert that binary number into 4 different answers in base 10 in binary, and i already figured it out how to add numbers together and im currently working on how to substract and multiply, i just wanted to say thank you so much for your amazing work and i will keep following you and watching your videos!

The amount of effort you put into these videos is incredible

Another insane video??? Congrats on 20k+ btw🎉

I appreciate the video man, keep it up!

I've been waiting for such a video... I finally got it

this is an amazing series ngl

dude i gave up trying to find a good video to learn how double dabble works. i was just looking for a tutorial to follow because i was one step away from building that 256 line encoder. this was so well done and informative i understood in 3 minutes. you should be a teacher

Well, this will be a lot easier than the 10-bit combinatorial that I was thinking of.

Awesome tutorial as always

Hi mattbatwings! i learned redstome from you! Thank you for the videos!!

I got hooked to redstone computer when I watched your videos so i watched every video of logical redstone and try to imitate it😂😂😂😂 ❤❤❤ty for your videos❤❤❤❤

Keep them coming! I'm hungry

I'm gonna watch this video 4-5 more times.

How do you make a double digit calculator? It seems like my output isn't enough to be decoded

Hi, hoping you can help me out. My device computes correctly, but it displays incorrect lamps (the correct ones also display properly) due to some extra torches flashing constantly. What is going on?

Hey, Matt! Maybe for the next Logical Redstone vid you could show how to string multiple 7-Segment Displays together.

Hey man quick question does the last line that’s sticking out on the original digit you built just replace the first line of the one you pasted? I don’t have world edit and I’m trying to figure out the spacing

do you have a machine that does the Binary to BCD in bedrock? the machine you're showing does'nt work in bedrock😭

oh my godddd thank youu for this tutorial!!!!!!!! :D

28:03 I thought you were gonna use adders but that was just such a great solution beyond my understanding

Literally watching this video as a refresher for an FPGA project for a 400-level digital systems engineering course. Lmaoooooo. Thanks a bunch!

Is the combinational design expandeble. And if you expand it to more than 8 bits how do you do the (orange box) layout.

Thank you so much i was having headaches about how the heck computers can literally like you know, calculate what 2,3,4 is with 2¹, 2^2, 2^3 even though these power numbers are actually decimal number and my final thoughts was decoders and i finally realized i was right! It's the FREAKING DECODERS!!!

Best explanation ever!!

i have a small issue: it works well but then i tried to expand design and make maximum 256 instead of 128. it no longer works with 256. when i input 256 only output is 0. what could be the issue?

@mattbatwings can you do reverse double dabble and if so how? im on bedrock (and no, im on switch so i cant chage to java) and the CCAs dont work (stupid XOR gates) so i need to do this to do your tutorial design for your calculator. pls help

Late comment, but is there a way to expand this design to include bigger numbers / more bits?

Yo can someone explain why my output is divided by 2?? I thought its bcuz i did not shift but after i made sure that everything is shifted i dont know

So what happens if the input to the double dabble thing has more than one 1, for example 11001000? Would it shift from 0000 0001 to 0000 0011?

what i do if i want to make a encoder whith 12 bits, for a calculator?

Thanks for explanation

Is there a set amount of times the algorithm will have to be applied?

Thank you! I was working on a binary calculator but couldn't find out how to do an input with multiple numbers. Thanks!

Great video

So when would it be advantageous to use the combinational design rather than the sequential design?

I wanted it to be converter to 8bit so with 8 outputs, il copypasted it 1time, the only thing that doesnt fit exactly with the video is the simetricality of the yellow system. And it doesnt work at all, please help

hello, what resource pack are you using?

In My First Big Redstone Project (Calculator That Adds Only To 30 (4 BIT)) I Made An Encoder With 31 Lines. Thanks For Tutorial!

This is amazing

This thing is really good.

Hi I got a question . Why is by the combinational Brinary to BCD only from1-9 not fron 1-15. If you input 1111 it´s to big, or am I stupid :) LG Silan

What if you decided to divide the binary number by 10 and take the remainder from it each division and send the remainders to a display? Would that be too complicated? I know it will be slower but it might be smaller than double dabble if you used the same design in reverse as your bcd to binary converter. You could make it stop dividing once it has a zero before the decimal point

Honestly though I like the serial one more :)

30minute redstone video? yes please

What resource pack do you use?

can you please make one that works in the newer versions of minecraft

I have a problem: When I put 1000 (8), I get 19. This applies with a few other numbers such as 11111111 (256) I get 213. Plz help :(

What's the difference between calculating the BCD from intergers and fractions? I saw a showcase with 2 towers, and the binary fraction part had 7 digits compared to 8 on the interger side, yet the tower was much bigger and a different shape. How do you do the .5, .25, .125 from .1, .01 and .001? Would be cool if can be built on the interger machine like how you build a subtractor out of a adder, and so on. Edit: It seems you do need 2 separate machines and they calculate entirely differently. Whereas the Double dabble algorithm is used by shifting and adding 3 if a group is 5 or greater, the other side of the point require subtracting 3 if 5 or above with a separate stack of units. The best (and only) combinational blueprint I can find of how it's done is in a video "Minecraft: Binary to BCD converter" by K van der Veen, 9 years ago. (I even have the file download that I downloaded 6yrs or so ago and it still works in 1.18). Every other blueprint demo on the web only seems to show positive intergers of Binary, or, just the decimal math conversion. And not the the Binary to BCD of fractions.

Is it expandable? Like to 12 bits or 16?

Thanks so much!

Please do multiplication and division next! Those two are pretty tricky and I haven't been able to pull it off for months now

You should do a video on how to use those commands u use to copy repeating structures

how do you make it with 16 bits?

Where do numbers 3 or 6 come from? Why it just so happens that for binary-coded decimal you need to add this exact number? Is there such a rule for binary-coded hex? Decimal-coded hex? Are they 3/6 too? Are they something else?

Can you make a tutorial for a 16-bit serial binary to BCD converter.

My binary that I need to decode goes up to 16 bit. How would I expand/change this design in order to work with that?

my faw is the first desgin cuz it uses all things we learned in this series

I love this

How to make the inputs 16 bit?

Is it possible to make a 2-tick "orange box"? It should be possible to connect the boxes if you work vertically. This would be much faster.

Hiw do you fo thr copy pasting so fast, is that a mod or how do you do it

The memory output thing just makes a redstone clock though.?

This is so interesting, will you make more of this, or it is the last video about binery?

Great video, thank you! I have a question about the serial binary to bcd-machine. Does it only work with 3 tick pulses for the input? If yes, why 3?

i love you man

can you show us a design for the opposite of this bcd to binary. for example if you want user input 3 digit number in bcd it can convert to 8 bit binary

I got it to work now, but it just flashes the answer it doesn't continue showing it, after 1 second it's gone

how i can stack them to 16 bit can someone help?

what is your carpet mod please share it with us

I made it & tested with just 1 bit bcd & it works fine when I add in the clear module to reset the decoders to stop the algorithm from pulsing forever my 8 & 2 lamps are always on they go off on reset but then come on again, they only go off it I remove the torches from the 8 & 2 lines but then the decoders keep pulsing!! Any ideas, this is on bedrock

Such a redstone god...

could you make a binary to hexadecimal converter vid?

4:12 5's aftershift is 1010, or 10, where what we "want" is 0001 0000, which is 10 in BCD.
