Way back in the early days of my youtube channel I designed this thing right here
I called it the programmable redstone display, and I have to say considering this thing's about four or five years old
It's still pretty impressive down at the bottom
We've got ourselves a handful of buttons if we hit one of these buttons you can see that the image on the screen
Changes and we get one of the pre-programmed images now
There are a handful of problems number one is the fact that these pixels are absolutely massive
We've got 3x3 pixels, which let's be honest. That's just that's huge and at the time
I didn't think they could get much smaller, but also the pre-programmed images are all we can show on the screen
There's not too much room for customization. You kind of get what you're given
That's all about to change today after a lot, and I mean a lot of very hard work
I have managed to build something that I previously thought was completely impossible
I'd have to say I'm extremely excited to show you this so here it is
I like to call it the pixel painter machine
And that's because each one of those buttons you see on the floor there
corresponds to each one of those redstone lamps so if you press one of those buttons
It will light up the specific redstone lamp that relates from that button if you press that button again
Then it will turn off that redstone lamp meaning that you essentially can draw pictures in redstone lamps in Minecraft
So let me give you a quick example
And the industry standard for showing off drawing machines is to make use of the smiley face
So I'm going to do a little bit like this. I'm gonna give him big
3x3 eyes and then I will switch on these ones as well so that'll be that 3x3 area over there and
Then I'm going to give him a big cheesy grin so I would say
Something a little bit like this, so I'm gradually making my way down
that should do all of those redstone labs, and I actually can't remember how high up I went on the side
I Can't remember all right. Let's see if we press all of these
I'm assuming that's good
Let's see have I gone a little bit too high on the redstone lamps on the left-hand side
Yes, yes I have alright so we have gone one two three four so if we just press those two buttons
Then eventually those redstone lamps will be switched off and you know what I'm actually not liking the big square eyes
So I'm thinking we get rid of the outside. Yeah, the out size don't know particularly good
Let's go one two three and let's go one two three on this side as well
And that should get rid of those, and we should end up with a fairly cool looking smiley face
Now it does take a little bit of time because as you can see this thing is pretty massive
But you know what I'd say the performance is relatively impressive considering its size all right, so that's the smiley face done
What if I want to change it up do a completely new drawing do I have to go back through?
Pressing all of the buttons to delete all the things that I don't want because that won't be particularly efficient
Thankfully I've already thought of this
And I've added in a reset button all you have to do is hit this button right here, and we'll see eventually
That this thing will kick into action
And we'll get a nice wipe going from this corner here all the way up to the top
And it should give us a completely clean slate to work with so now we can create some new images
for example this one
writing and also a smiley face or for example this one my best attempt at are creating your favorite kitchen utensil a
Spoon and of course it is still tricky
We've only got a 10 by 10 pixel area to work with it's not exactly 4k or this one now
I can't quite make out what that one says
Sub me?
Subscribe to me maybe subscribe to my youtube channel
I don't know I mean this one wasn't done by me
I mean off as if as if I would be guilty of that sort of shameless self-promotion
I mean, let's just be totally honest
That would be completely out of character anyway
Subscribing to my youtube channel liking this video leaving a comment down the comment section and follow me on Twitter aside
I really quite like this thing and now I'm going to try my best to explain to you how on earth it all functions
I'm a tiny bit nervous for this one because I'm never particularly good at explaining my redstone contraptions
and this one is
Considerably more complicated than most and if you don't want to listen to me ramble on about how the redstone works
But you just want to play with it yourself
There's a world download in the description knock yourself out now it all started with this game mechanic right here
When we turn on a redstone lamp it turns on instantly, but when we turn it off
a tiny bit of delay
It's really tricky to see but you can see that
We actually have one tick of delay between me flicking off the lever and the redstone lamp turning off, which means
That I can do things like that
Can you see I've managed to turn off and on that lever
without it actually being visible in the redstone lamp and that got me thinking I
Wonder if I can create super fast redstone clocks that will keep a redstone lamp on
Which of course I could now this design is very loud
But it's also very handy to have because it's only two blocks high
And it's only one block wide and most importantly it can be stacked next to one another and it can be toggled as well which
Is very important for this design, so here we have for all of the redstone clocks lined up
Here is the output and the output of that runs into really [a] big long observer strings
Which are essentially transmitting the signals from that
Redstone clock all the way around here into this area along like this
And then they travel down like this up like this along here, and then into our display. Why the long trip?
Well, it's because we had to essentially flip the redstone signal time for another example now
We've got ourselves a scale model of the display
now the thing that made it tricky is that I wanted this lever here to correspond to that pixel and this lever here to
Correspond to that pixel now if we take her over to the slightly larger one the reason that I wanted this is
Because if this button corresponding to that pixel and this button corresponding to that top pixel if we drawn out our smiley face here it
Would have come out upside-down on the screen, and that's no good, but despite it being no good
It would have been really easy to build because if you want to connect up this front lever here up to this bottom pixel all
We have to do is do that and then to connect off the back one to the top pixel
We just have to do something like this. No crossovers there Bob's your uncle you've got yourself a working display
However if we want to do it the correct way
Then we run into a bit of a challenge because we have to run the redstone signal out like this and into this top one
And then we have to run this back lever out like this
We have to do some form of crossover in the center and connect that one into that one
It's a massive headache
But I managed to solve it and that is using this observer setup right here
Now what this will do is will flip over all of the redstone signal so for example if we hit this button
In this corner that will send an input through into this observer
And you can see the observer is the one that's being powered for than the output after this
processing is happened will be over on this side so the actual redstone output is flipped because
Whereas it started on the right-hand side it is now on the left-hand side obviously,
We've gone round a corner here, so now we have the output on the left
Which means that we flipped over our redstone signals and now it's the correct way up, and we aren't mirroring the image
Brilliant off so that's what happened. It's just a simple case of
transporting that observer signal through all of these observers and
Making its way over onto the screen then six or seven hours of debugging and trying to work out what on earth has gone wrong
Later you've got yourself a pixel painting display that actually functions
Oh, but before I forget. There's one other feature of this thing that I personally really quite liked in fact
It's probably one of my personal favorites, and that is the clearing feature and to be honest with you
it's
Super super simple all it does is it retract all of these redstone blocks so all of these pistons
Extend and retract so any blocks that are sticking out will be retracted and then it spits out all of the redstone blocks which will
Power all of our redstone clocks mean that we aren't going to get any redstone lamps lit up on the screen
Really really simple but looks cool, so we go
I think that just about covers everything if you're still a little bit confused and of course
I'll try my best to answer down in the comment section and of course there will be a world download down the description if you
Do want to see all of the Redstone for yourself, and if you want to draw your own things;
Please do submit your drawings to me on Twitter because I'd love to see all of the creations that you come up with but anyway
