I Built a Calculator in Survival Minecraft 

This is such an amazing video. It was an absolute pleasure to help! Making a calculator in ~2 weeks is no easy feat, and the final result looks amazing! Proud of you bro!

Dedication is absolutely unreal.

It's cool to see that you get quicker at recognising why things went wrong and where things went wrong. You're deepening your understanding of redstone which makes you more efficient.

Y'know, having Rekrap as a person to teach redstone would be amazing, It would actually probably start to make me a Redstone addict.

What could go wrong spending a month building a highly flammable build

This guy is the definition of “never ever give up even if it takes 71 years.”

imagine if rain destroyed redstone.

Rewatching this video and its still absolutely INSANE how you managed to do all this, and also that redstone is just able to do this in general. I always forget how complicated it can get Awesome video as always :D!

That's why, I love redstone. First, it's really frustrating, but then at the end, it looks really fancy and you feel really proud that you have built this.

All the leaf scaffolding looks super cool. even though it's wasn't on purpose, they look like really cool vines snaking around the machine. Awesome job on the calculator Rekrap! A lesser man (such as myself) would have given up and chucked his computer out the window!

This is actually crazy. So much dedication and determination. Keep it up Rek!

this is such an amazing idea for a video! best minecraft video ive ever seen on youtube! wildly different tactic to beat the game, but also very intertaining as a redstone fan!

As an IT technician, it was really fun to see rekrap learn how binary code works and such.

Rek now holds the record for calculated any% with no speedrun calculator 🤣

DUDE REKRAP THIS IS WHY I LOVE YOUR VIDS, YOU TAKE ON CHALLENGES AND EXPERIENCES YOU HAVE NO PRIOR EXPERIENCE IN AND YOU ABSOLUTELY CRUSH IT WITH YOUR DEDICATION OR JUST WILLINGNESS TO A NEW EXPERIENCE, ITS RLLY GREAT WATCHING THAT, ITS THE BEST THING ABOUT UR VIDS, LIKE EVEN WITH THE DREAM BOAT CLUTCH YOU LEARNT, I LOVE THE MINDSET YOU HAVE WHILE DOING SUCH VIDS, AND ITS WHAT KEEPS ME WATCHING SUCH VIDS AND ENGAGED THE WHOLE TIME- I ABSOLUTELY LOVE THE JOURNEY YOU SHARE OF AN INTERESTING UNIQUE CHALLENGE YOU TAKE ON WITH NO PRIOR EXPERIENCE IN IT-

For video recs, I feel like many of us love the more chill videos on your second channel just as much as the super planned out, goal-focused ones. would love to see a video that’s just like playing bedwars with friends, or speedrunning with people :)

As a computer engineer it is really fun watching rekrap learn the basics of digital logic.

18:55 Never seen Rek's water bucket out of his hotbar until today. Shows how incredibly serious he is about building this 😅

Bru, I can't even figure out how to make a hidden door, or even how to turn off a Redstone torch without making it look stupid.

Such a good video! And (from what I can tell) a pretty original idea! Thx for producing such a banger!

I love how he builds a whole ass calculator to beat minecraft, and then proceeds to casually zero cycle the ender dragon as if it's nothing.

I have attempted logical redstone many times. and speaking with experience, he made it look VERY simple.

Well done! Doing a project like this on your own sounds like a massive learning experience.

12:15 literally a wolf in sheep's clothing lol

ready to get impressed by parker's extreme skills and personality ! keep going man

Dedication is absolutely unreal. A real legends to be able to learn all this and grind the resources and make it.

It's amazing how you can make a seemingly boring idea, an interesting video! Keep of the great work ❤

*making a redstone monstrosity* *has to mine for redstone in the first five minutes*

Parker is literally a Jack of all trades when it comes to Minecraft. He’s actually just insane

So you are now a redstoner, a speedrunner and a builder. You should try some pvp like you did in your lifesteal days. Keep it up, this video is great!

I spent weeks trying to do an adder with a display, and you did this. You're insane!!

this video is just absolutely amazing. i just have no words for it. its just insane how someone like rek can do this in ~2 weeks IN SURVIVAL? big big props for u my man keep it tf uppp

The reason why it’s called a ‘bug’ when there’s a problem in a computer was actually because a moth flew in a computer (the ones that are the size of a room) and got smashed stoping something working. So the people who made it had so send someone in to crawl in the computer to figure out what happened.

watching this as a programmer is so funny. I've made calculators, but I would have absolutely no clue how to do it in Minecraft (other than the basics of binary). Huge respect for learning this

Thanks for you’re hard work i really enjoyed this video peace out❤

I’m a freshman in computer engineering, I found this video super interesting! Im taking a course which is an intro to digital logic (among a few other things), and I found it super cool how you basically learned and applied digital logic here. Massive respect for the division, floating point division is a pain (doing one problem takes me like 5 minutes). This inspires me, I might boot up Minecraft and try designing an ALU (we already designed one for a homework assignment, but it would be fun to implement in Minecraft)

Rekrap is so insane to build and do challenges like this.

Man I wish I had this level of commitment.

I remember this video coming out and thinking it was super sick, so i took so time ro learn and i now understand this stiff pretty well thanks to matt's LRR series

I have watched this video 10 times, it is such a good video, keep it up rek!

It’s actually really surprising how much doing feats like this can teach you about not just red stone, but things like binary coding and logic gates, things real calculators and even smartphones rely on to function. I would 100% recommend people do things like this, maybe just in creative mode though.

Great job Parker, now you just need to add the square roots, exponents and much much more! Great video, subbed!

I rarely watch minecraft videos but im thoroughly impressed by your video, keep up the good work

you are just becoming a god at everything in minecraft its insane watching you improve!

For the question of what videos to make for more frequency, I'll be honest most of the Minecraft creators I know that upload super regularly do SMP videos. For other ideas, maybe there's fun interesting stuff you could do with classic challenge maps (things like skygrid or falling falling) but updated to new versions for new objectives? That could be a good fit for your channel.

This is how I feel about coding all the time, debugging all simple mistakes like a typo, real proud of you for figuring this out. I wouldn't have even attempted this!

This just shows how many cool things you can do with Minecraft and some of the ways to make it more challenging or more fun

My favourite Rekrap video by far. Just seeing him have fun and do redstone is awesome :3

This editing is next level, Rekrap seriously doesn’t half ass anything

The matter of time this man puts in is crazy he probably put like months into the armor stand project and now he is phusing himself far so respect to rekrap

this is literally so much effort dude, take a bow!

I don't believe you are a real person, how can someone be so talented, entertaining and genuine. I just got back from a week away from all tech and stuff, out of all the amazing videos that have come out in my absence, yours made me almost fall out of my chair, never stop being you, you are amazing.

17:46 Matt thought I wouldn't notice the purpledragonpooop account xD Seriously though, you're crazy man for building that all in survival, great job!

As someone studying computer science this was the most fun I've had with a video in long time. Reminded me why I love computers so much :)

6:30 as an amateur programmer I wanted to say the reason this works and with only four blocks is a Karnaugh Map. Basically you make three columns like below. The first two are inputs, and the third is output. A B / 0 0 X 0 1 X 1 0 X 1 1 X Program the X’s as the values (0/1) that you need, then convert that into a K-Map like so. Let’s say our “X” row is 0, 1, 1, 0. You then would make a box like below, with the proper coordinate values. The corner is blank, so I’ll use a “/“. The values with quotation marks are coordinate values. / “0” “1” “0” 0 1 “1” 1 0 With this, you then use logical operators to convert the above K-Map into a logical expression. I’m not going to go into that here, but the short answer to my example is that the output is 1 if and only if the operators are different, symbolized as -(A=B)

Ngl last edit gave me coosebumps 😮👌💙

you know it’s gonna be a good day when rek uploads

Welcome to the coder's daily debugging experience lol. You said you wanted suggestions for future videos so here's one: I beat every Minecraft Mob in 60 seconds. It could include a cool setup of obtaining every mob, bringing them together, and then building a rail cannon for the dragon. Would also have an epic finale

POV: Mumbo Jumbo’s simplest build

I am once again reminded that redstone terrifies me Insane dedication to this!! Great vid!!!

This is incredible. I am a redstone engineer myself and i know a bit about computational redstone. But the speed. You learn so fast. Its insane. Huge respect.

soon rekrap is going to be an expert in every niche also, as a programmer, I can confirm that 20:50 is very relatable. but it doesn't take 2 hours to add a semicolon

Honestly, from your request to give you ideas for a short to make Minecraft video, I think I won't 😁😅 because your content is definitely worth the wait. Love your videos, and I never fail to learn something new from your videos

I love your dedication man, keep it up. I am a small content creator myself and I wish I have your dedication

Gotta love the clever ideas Rekrap uses. I'm happy to be able to watch it.

I love your variety! Both this and your armor trim vid are kinda outside your normal genre, and I'm all for it! Nice job, what a well done vid!

Wow this is so cool, congrats good job!😊

This guy just casually learned how calculators work in a couple weeks and made one in a video game. Props to you my guy!

this is amazing rek! your dedication and time spent on these videos is always impressive, even more so that you took the chance to learn all of the redstone yourself where others likely would’ve simply followed a schematic. amazing video

This man never disappoints.

Great job this is really cool!

i thought u we’re just making a calculator but making one from scratch is taking things to anooooooother level! great job rekrap

Absolute banger my man! What you do for us is incredible

Suggestion: Going through time, getting Minecraft's most broken toolset and armour as possible I'm not just talking 1.14.2 multiple protection. I know there's a snapshot of 1.4 that lets you enchant literally anything with an anvil, and then some. I assume you'll probably research other ways to obtain enchantments on things you otherwise normally shouldn't have them on, over the course of Minecraft's history, there's been quite a few. I wonder just how many of them there are?

loving the new editing style

Love this video Rekrap!!

You're a mad man, I'm so excited to see what you do next

Wow this was really fun to watch! Mainly because i made one personal project in which i made a bunch of computer science stuff, like i watched some videos about binary, logic gates adders and i saw it could be made with redstone and started doing it I made a really basic calculator but im more proud of the fact that i made a working computer ram and a CPU in minecraft, this is not so related to the video im just really proud of that :D

Welcome to electrical engineering! One of my favorite subjects! (Tbh I’ve just finished learning this stuff this year before I watched to video and it was very satisfying for me idk why, just no one ever talks about binary in a cool way and I was happy to see him do that 😊)

Don’t see these kinds of vids too often❤ this is totally hilarious 😮

This is super sick! If you want a video suggestion, maybe try and make your own adventure map? I think that could be unique and fun :)

I love how creative and different ur ideas are! You are constantly pushing yourself to learn new things and not only that but grind for the materials to even execute them?!?! You're incredible, I hope kids of today can grow up looking up to you. The cinematics of this vid are awesome too, love the division looking all evil. THAT ENDING IS INCREDIBLE WOW

so glad this series will continue

That final montage where you beat the game and built the calculator was awsome

this is ablsolutely crazy. The fact that you spend so long to overcomplicate something already complicated is just pure dedication. Well done Rekrap, you are awesome

if rekrap isnt included in that montage at the beginning of minecraft live, i'm gonna riot! keep it up, this is so cool!

I dont often like videos in general(Mostly because I forget to...) But this one, it seriously impressed me.

you should totally make more videos with matt, his stuff is lit

i love how you use leaves as scaffolding, not only cheap and transparent but makes it look aesthetic :D

Hey Rek! Awesome video, love the dedication. Regarding 20:29, an idea for a video could be to put out a channel community post and do some fan made challenges and record yourself doing them. It’s a simple concept but I feel could make a fun video, and shouldn’t take months to make

You've been my favorite youtuber for a while

Great video! Congrats, you just built a computer. It's an incredibly difficult task but man, is it rewarding.

you can tell how much effort he puts into his videos and i can tell you just love making content like this

it is so crazy the amount of time and effort he puts into his videos

As a CS major, sometimes the best solution is to take a break from the problem. I would be staring at a question for literal hours just to wake up the next day and instantly realise the solution 😂

Very underrated video, some people don't understand how much time and determination takes

damn, the effort is insane. I wouldn't imagine this, while beating minecraft, besides, I'm bad at redstone already, lmao.

I can't believe how this guy never quits after me messes up. this guy is literally the meaning of inspiration

this guy literally puts so much effort into his videos. He straight up learns things every new video

This inspired me to get into logical redstone thank you so much
