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.

imagine if rain destroyed redstone.

Me figuring out what a comparator does

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

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

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.

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

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

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.

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

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.

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!

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) Also before anyone says anything, i did in fact go down the femboy programmer pipeline:3

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 😂

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

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

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

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!
