A claw-arm idea

Tried simulating a piston extender with slimestone and made neat claw-arm by accident.

[@zhascha]

actually a real nice concept borrowed from computer science theory where multipliing 2 numbers is a real hard thing to do for a computer and ppl that are way too smart broke the complexity of a multiplication algorithm down to 2n from n squared

[@MehrGills]

Isn't it actually down to O(nlogn) now as of 2019 for mult(a,b)?

[@zhascha]

@@MehrGills you mean the harvey hoeven algorithm yeah

[@docopoper]

I think to make the retraction efficient you'd really want to have each segment function as a flying machine that can fly back to the retracted position. And then send a pulse to start each of them in sequence. Might actually be a useful invention because extending is so fast.

[@aikensource]

The Algorithm is starting to show me your stuff and I really like it. It's carefully thought out, scientific testing, but your presentation is very easy to listen to and enjoyable. Keep it up!!!

[@oinkymomo]

im pretty sure that the best you can do for any sort of multi-piston extender is linear out quadratic in. extend back to front, though that only works with up to 12 pistons, but you need to retract: - the block - the first piston then the block - the second piston, the first piston, and the block - etc. that's triangular numbers, so quadratic. I'm pretty sure the only way to do linear retraction is with a single free-floating flying machine

[@bengineer8]

With parallelization, you can retract a block and n pistons in 2n-1 iterations. Example with n = 4: B p p p p Bp p p p B pp p p Bp pp p B pp pp Bp ppp B pppp Bpppp Would probably be easier to make them all flying machines than add the logic for that.

[@haph2087]

On the example with just the observers and pistons, you should change the concrete to glass blocks, so you can prevent cross-talk. When an observer powers a concrete block, it the concrete block can activate an adjacent piston in a different slice, which will make the firing order of that slice really complicated. really, generally, I'd just recommend having a 1 block gap between the slices. An alternative solution is to use rails underneath, rather than observers, so all slices get powered on the same tick.

[@EvanG529]

I discovered something similar to the first contraption a couple years back, I found a block of observers and pistons that can be used to make an extendable 6-wide door.

Why did I read the title as A White claw Stone-arm Jazz Idea

[@jackweslycamacho8982]

I can already smell piston extenders sorting algorithm videos

[@zacharybarbanell1064]

There's a solution with linear extension and quadratic retraction, by sending a flying machine along the line that finds the last two segments which are separate, and instructs the closer one to retract, propagating the retraction signal to everything after it. Sounds complex to design, though.

[@niceguy6384]

bro are you some kind of scientist or something i can't even figure how a simple slime flying machine work without a tutorial

[@GOAT_GOATERSON]

I have a challenge for you, can you make a sorter that sorts evokers from pillagers, witches and vindicators? Because I want to use a lot of evokers in a creative trap but it's really hard to seperate them from the other raid mobs because they're very similar.

[@isaacisaac_real]

For the first part of the video about pushing pistons and a block with observer timing you can find something similar in cubicmetre video in orbital strike cannon

[@toriknorth3324]

To get both extention and retraction to be linear it seems like you need to be able to pass signals down the chain in both the retracted and extended states. The simplest way to retract that I can think of would be to have a single signal pushed down the chain to the end where you would have a movable clock or engine that could simulate the player clicking n times.

[@hlibprishchepov322]

Try to use autopullers and manually activate all from end to start it might help with in both ways. I will try to solve in too, but now I can't try it.

[@blacktipgaming2098]

This makes me wonder if it is possible to have a longer piston extender that moves across the x,y and z axis

[@killingtimeitself]

you can actually do something along the lines of this using flying machines, instead of self returning flying machines you build them such that they fly out one or two blocks and then start returning due to updates chaining such that it forces it to return. I've gotten triple extenders to work based on this mechanic. double extenders are easier, theoertically i think quads should be possible but i've not tried.

[@MrRyanroberson1]

Ilmango made a flying machine that carries a data tape that rotates it one blocm per blocm moved for programmable distances

[@CYXXYC]

timelapse looks like those sorting algorithm videos

[@morgane3501]

if you look at the orange block, it becomes pretty clear that it will never retract all the way in. if you look closely enough, you can see this line going through the same state twice(including the input of course), meaning we have seen all the states of it's cycle, and in none of them is the block fully retracted.

[@mhtsarasakris8889]

hey seems like a cool puzzle where do you find it/similar ones?

[@whitestonejazz]

The KZbinr SpaceWalker told me about it

[@danielriquelme5766]

I don't think the last arm has a linear extension time, correct me if I'm wrong but because for every piston to be moved all the previous ones must be moved too (for retraction) that ends up having a quadratic extension time

[@conure512]

so is this your way of telling us you're making one of those arcade crane games using redstone?

[@whitestonejazz]

If we can get one of these things on a 4-way flying UFO, yes.

[@Neolcy]

wait how did you get that to work, like how do you get a /player (player to do something for you?) is it a mod or a plugin or something?

[@Neolcy]

like how do I get that too, a bot / ai player in minecraft?

[@whitestonejazz]

I use "carpet mod"

[@YaPhutYT]

3:49 when you count to 65535 in binary

[@Happy156]

this is kinda out of nowhere but do you have a patreon?

[@whitestonejazz]

Nah. no patreon. I'm thinking of adding a 1$ channel membership but my wife and I wanna design the custom emojis ourself before its an option

[@zacharybarbanell1064]

I imagine you'd need quadratic time even in the best case. It's certainly possible if you're willing to have both quadratic time and quadratic space, but kinda gross.

[@Xabraxus]

I think this is just an application of harmonics.

[@TavishMcEwen]

Yo is spacewalker still around in the community?

[@whitestonejazz]

They messaged me with the puzzle. Beyond that, I haven't from them in the past year

[@TavishMcEwen]

@@whitestonejazz ah. They're one of the people i miss from when i was slightly active in the rs community

[@derrmeister]

why do you use a bot player to click a noteblock instead of just using a clock exactly?

[@whitestonejazz]

easier with flying machines since a player is easier to move than a clock

[@auxod3219]

Who is Space Walker?

[@whitestonejazz]

Another Minecraft KZbinr. They made this video: kzbin.info/www/bejne/h2O8hXZtYtZniaM
