- In this video, I look through the various redstone adders that have been created over the years, and show how CCA adders completely dominate them.
This and my other videos are done on the Open Redstone Engineering or ORE server. Anyone is welcome to come on: There's a lot of awesome redstone builds, and a lot of brilliant redstone engineers who'd love to talk redstone with you. There's even a school of redstone where you can learn redstone from the best.

3 Years later; Benny still hasn't hit puberty. Great to have you back, Kiddo! :3
I think he has. I think he has a low pitch undertone to his voice.
OMG he's back
BENNY!! YES! ARE YOU BACK??!
BENNYYYY
AYYYYYYY
MAH BOI
Its good to have you back.
You are the best redstone and computing teacher ever!
Wow benny! welcome back to youtube!
Benny when you said "Let's say I wanna add 3" I already knew you'd add 5 to it. Some things never change lol
I had a double take in my notifications. I was not expecting this!
We missed you soooooo much
It's crazy that 3 years later there's still redstone innovation to do. I totally thought people would have thought of everything by now.
BOY YOU POSTED AFTER 3 YEARS
You are the best benny
thx to you i got a 8 for my informatics test because you explain binarie SO GOOD!!!!!
Welcome back!
Yay you're back
Nice having you back!
wow its so good to hear your voice again Benny, look forward to more redstone.
You are back !!! omg I cant belive it :D
Welcome back finaly
IM SO HAPPY!! HES BACK!!
Your voice is as soft and soothing as ever. I missed you so much :')
Glad to see you back Benny :) Cant wait for more
DUDE 3 YEARS ! WHAT THE HECK 3 SHIT YEARS AFTER!
benny i am really glad to see youre making more videos on adders!!!
BENNYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY! YOU'RE BAAAAAAAAAAAAAAACK!!!!!!!!!!!! WE MISSED YOU!
I'm so happy your back!
BENNY YOU'RE BACK!! Great video btw
But Benny, don't forget that the Instacarry Adder has something no other adder can offer aswell: Bitwise Operations. It can't be any simpler to make a ICA OR the inputs. But from the video, I'm pretty sure it's impossible to make this adder OR. I'm also not sure how I would cut the carry of this adder. So in my opinion, the ICA is still the best, because you can make it OR, XOR, AND, NOR, XNOR, NAND with very little additions to the design, which I think is far better than vectorisation.
Btw love to see you back. ;)
It's actually still pretty easy to do bitwise operations with this adder, arguably as easy as ICA. The tricks are just a little bit different.
For example, both inputs feed to the same wire. That right there is your OR; just add a comparator AND gate that sends it to where the XOR output is, and a slab tower as a control wire. The beauty is doing that will automatically cut carry for you whenever you OR, no extra trickery needed. There's tricks for everything else too, plus a few more things that aren't so easy with ICA's (like bit shifts/bit rotates) and I'll be showing that off when I make an ALU out of this.
I guess I need to play with it for a bit. :P Looking forward to see your ALU. Don't stop making videos this time. :P
@@bennyscube That's a really crazy trick along with the flood carry thing, turning the adder into an xnor. Saved up a whole bunch of space.
Welcome back
WHAT?! You're back!?? I missed you!!!!
oh my god
WELCOME BACK OMG
He's back!
Benny, I found your channel after you stopped making videos, so this is my first official comment, yay. Imperative question: how to convert base 2 to base 1, that's the only thing (probably not) that I need to know to finish my first MC computer that I never could complete as I can't make the program counter. I'm just too happy you are back.
Hello, nice to meet you Daniel! I think what you're looking for is a decoder. I recommend the one by properinglish; he has a great design and does a good job explaining it: th-cam.com/video/upskugeEW4o/w-d-xo.html
ohh my goodd ive been waiting soo many monthsssss
Years**
Heyyy you're alive!
Did not expect this
*AWESOME!* Glad your back! Will you be continuing making videos?
never thought i'd see the day "Bennyscube has just uploaded a video"
You are back!!!
I'm making a tutorial of one of the computers you built on my new channel (130Bacon,) I gave you full credit!
Thats me. :D
130Bacon Yes.
HOLY CRAP HE'S BACK
Glad you're back. I'm guessing you just finished a bachelor's in computer engineering or something. What are you plans? What's going on with life? Are you gonna make a more organized redstone computer video series? You said yourself that first building a redstone computer series left you with a pretty bad computer without an instruction set. Perhaps show an implementation of your advanced computing series?
why haven't you made a video in like 3 years???!!!
You _must_ make a video on that CPU you showed
h-holy shit
I'm speechless dude, I can't believe something I designed so many years ago has had such an impact.
also THANK GOD someone who knows how to do youtube made a proper tutorial ;^)
Clicked that bell ASAP when I saw this
He's back
Welcome back!!! I thought your dead (not you just your yt)!
Bennnyyyyy welcome back from the dead!!
THE HYPE IS REAL!!!!
OMFG he is BACK !!!!! :D
This was recorded recently, June 25 2017, so i guess he is back!?
BENNY IS BACK! OMG
Awesome dude!
Hey, maybe a bit of an odd question, but what kind of adder design would you “recommend” for an 30 bit calculator?
facinating!
You're not leaving again anytime soon, are you?
Wow. I must have just missed this invention (as I left ORE a while back). You gonna be on more now? :D
Indeed. I've been on fairly regularly for the past week or two.
Awesome. I'll drop by at some point and say hi :)
I can't believe it's been already 3 years I've been sitting on this chair busting my nuts! ^_^
Are gonna continue thebennybox too?
Please be a permanent return
Um...
cool
*tutorial in next episode.*
dang it, we have to wait three more years
Holy crap I thought Benny was dead!
lol me too
Whats better? CCA or CSA?
They aren't comparable. One is 3:2 and one is 2:1.
Hi Benny!
I mean, it isn't really random for "all intents and purposes" because as you said you can compute the upper bound which means that you can wait on the upper bound as a steady time at all times. Slow? Absolutely. Random? Not when used in a practical manner, in fact only if it is used in an attempt to discover the output at times OTHER than the upper bound.
By the way, thank you for all the vids and for posting more! You really taught me so much about redstone (and adders)
How do I make a 16-Bit CCA?
Take the carry out of the final bit and repeat it. This is unfortunately the downfall of CCA because it will add a minimum of 2 ticks every 8 bits, and it will also ripple every 8 bits. Instant carry is only an additional 0.5 ticks for the second 8 bits and an additional tick per 8 bits beyond that. I have an idea for Pauk's (from ORE) ICE logic can carry instantly infinitly with no instant repeaters. I've never tested it though.
Seriously man, where have you been? No updates or anything has made us suspect that you are dead.
OH OH OH OH OH OH OH
yaaaayy
THE SECOND COMING IS UPON US
Holy fuck nostalgia
What was he doing for 4 years?
You're alive?
CCA = Carry Cancel Adder ,it mean if u say cca adder it will be carry cancel adder adder
Finally 😂
OH MY GOD
WHAT THE
BENNNNYYYYY
ALIVE
where the fuck have you been?
oh shit you're still playing Minecraft
Lol glad i remained subbed
Benny switched to Linux :)
HI
:)
BENNY
It isn't perfect, cause the carrytower could run out of signal strength
Instant adders are possible
And they are huge and full of pistons. Most people rather use a 4 tick adder where you don't have to worry about 0 tick delays, 0 tick pulses and sticky pistons loseing their blocks.
Ha looks who's back! Hope you will never use command blocks :P
RIP CLE. ;_;
The good news for CLE is it can still do a few things CCA can't yet. Most notably, in sequential circuits, CLE can still make slightly faster inner loops than CCA in most cases. I know someone has a CLE ALU that can do all the usual features and loop back to inputs in 5 ticks (and I think I hear someone's working on 4, although I haven't seen it yet). Plus, there's a piston-CLE variant called ICE that currently holds the title for fastest adder in minecraft, at 2.5 ticks on both edges. In general though, CCA is the way to go nowadays.
Also, I just want to add that I think your adder paradigm is awesome. It's a really creative piece of logic, and it's a lot of fun working with it, even if it no longer dominates in all the areas that it used to.
Hahahaha thanks. I'm glad that a real good solid state adder finally got invented, this was pretty much what I wanted out of CLE anyway.
yoy he said my username- Cube
benny....like bro... i feel so much hate right now. u have a mike for vids, but no mic to talk to good 'ol De :(
so? i met him
WHAT
IS HE HERE?!?
I thought you died
watch him not post for another three years :)
more inconsistent than ksi
BENNY
