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

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!

[sethsmith]

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

[jwchew]

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

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!

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!

[FlippingMiner]

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!

[thehuy]

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

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

I really like how the series is progressing <3

[TavishMcEwen]

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

[amnetik]

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 !

[kengored_alt]

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

[orsonjones]

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

[rxREDSTONE]

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

[ThatGeometryDude]

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

[herne]

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

[school]

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)

[matchey]

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