Having to refill the colors seems like the main downside of this. With how long it seems to take it would be nice if you could just set and forget and not keep checking on it. You could extend the color ‘hopper’, and modify it so you can see the height of each color stack with tick marks for every 10 plates. Then the program could print out the number of each color that is needed in the current design and you’d know up to what tick mark you need to fill each color at minimum to complete the ‘print’ without needing a refill. The program could also prompt the user for how many of each color they have and do two passes on the image: first for each pixel compute a ‘difference’ value for each available color, then in the second pass always first greedily assign colors to those remaining unplaced pixels with the lowest ‘difference’ to the colors, tracking the remaining colors you’d have and always assigning the next lowest ‘difference’ color that also is still available. This should result in the final design never using more of a color than what you have, while still looking as ‘close’ as possible to the desired image. A neat side effect of this is that you could effectively choose palettes - eg. If you only specifying counts for various black/grey/white plates then the final design it outputs would be completely greyscale. Same if you only input counts for blue tones. You could also include dithering as a means to better approximate colors and better handle not having enough of a color.

[@hjewkes]

If you wanted to speed it up, you could have the pick and place be able to grab more tiles at a time and have each stack be able to dispense tiles onto a belt. Then the dispensers could queue up the next strip of tiles while the gantry is placing it, and you reduce the number of gantry trips

[@vitorbonamigo]

The fact you can remove the boards and keep the print just makes it better

[@JNGamez]

If you attached this machine to Dave and then Dave would be a Lego pixel art machine and make hands for Dave to place the pixels

[@mathijsfrank9268]

The reason making the image smaller makes it all blurry is because it (probably) uses bilinear interpolation when resizing the image. With whatever software you are resizing, you can probably change this method to use nearest neighbor in stead, nearest neighbor will simply use a single color from the original and use that, there's no average. This achieves basically the same as what you did, but you don't have to reinvent the wheel.

[@alexshepherd]

I actually thought the scaled image at 8:25 looked better than the eventual result. Anti-aliasing by grey pixels helps to smooth the lines while keeping the correct shapes, and the machine has grey 1x1s to use. Look at it from further away and the “ugly, washed-out image” looks better than the wrong-shaped sharper-coloured version. Darn, now I have to build the whole machine myself to get that result I prefer :)

[@StarrySnippets7]

i have a suggestion to make a pixel art with good quality u can divide the picture into 4 part each 32 * 32 and then create those 4 parts and join them together . if you repeat this process again and again you can have a 1024 * 1024 pixel art EDIT- Subscribed after watching this video

[@CreativeMindstorms]

I would need a million lego pieces, but sure that would be cool! Oh and also: it would take over 3000 hours for this machine to complete it!

[@StarrySnippets7]

​@@CreativeMindstorms you can make a smaller version 256 *256 that will also be good and more amazing you can achieve this by upgrading the size of the portrait like form 32 to 64 and then to 128 and then to 256 this would also be good and you can also create a video on it

[@theawesomer]

With the realization of ones own potential and self-confidence in ones ability, one can build a better world.

[@majsstenen]

When downscaling to 32x32 you can choose the most frequent value instead of the center value to avoid the smudged colors. This happens when accidentally choosing colors in beteween two colors since they've most likely had some kind of blending in between in the original image.

[@CreativeMindstorms]

Hmmm yeah that might have been a good way to go about it.

[@HypnoMotion]

[@Progs420]

@CreativeMindstorms Ja bitte gern! Habe ja auch nur Tatsachen geschrieben!

[@Jay_Noir]

Cool project! To capture how a human would draw things like a sunflower at this scale vs. the garbled mess you get from downscaling, you need an ai trained on pixel art. There are stable diffusion models that do this. You could even train your own on lego-colored 32x32 images specifically. Another idea: You could use the full range of lego colors if you simply do multiple passes. You could even go so far and make the software plan ahead and ask for stacks of specific colors in whatever slot it wants, so you don't have to interrupt so often to refill a single color.

[@CreativeMindstorms]

Those are some good suggestions! If I ever make a version 2, I will definitely take a closer look at them!

[@thepalewriter101]

you should hook up dave to the pixel art maker, and randomly, dave just makes whatever he wants.

[@bobblebardsley]

This is very cool, I have a slight love-hate thing going on with how you get pink tiles in the finished 'print' that look like jpeg artifacts (or I suppose more like a gif with a very limited colour palette) but I've made favicons for websites in the past and I know how hard it is to work with so few pixels. I actually think the 'printed' physical Lego versions look even better than the on-screen previews. The whole thing looks very professional, like Lego could sell it as a Lego 3D Printer kit or something.

[@CreativeMindstorms]

Thank you for that! Working with few colors and pixels is indeed hard to do. I also tried making the saturation of the colors a higher priority when deciding the closest color, but it unfortunately didn't help with getting rid of the pink and green pixels. Thank you for commenting and leaving your thoughts!

[@deniseedit.]

How about adjusting the machine so it preloads the colours in the programmed order. So instead of going to get the studs everytime, it loads 10 studs at a time.

[@Leon1904ffhhsus]

Heck, load the whole image while it's building! Definitely do get inspiration from bead printing robots!

[@CreativeMindstorms]

@denisedtd I haven't even considered that. That might be a lot faster!

[@Leon1904ffhhsus]

Multiple placing heads could multiply speed as well, they could be mounted on the same y axis actuator and place pixels simultaniously but 3 or 4 rows/columns apart

[@Leon1904ffhhsus]

Also, can't image generators output directly in 32x32 pixels?

Would it be feasible to have the arm pick a complete strip of legos of one color and put them on the board? So it saves time of returning to the supply for every single pixel. It also saves you time to watch over it for the refills because you only have to refill it when all the colours are empty.

[@CreativeMindstorms]

Yeah I think that would save a lot of time. I guess I haven't thought enough about time when I started. Thank you for the suggestion!

it's more pieces you may have to buy... but if you can make it so each color holds enough blocks to fill the whole print area by itself, then you'd never need to refill it.

Would be cool if you can figure out a nice compact way to hold that many bricks for each color.

[@mrhobbles385]

Regarding the issue of colors running out, you could make it so it doesn't stop until all required colors are empty. If the hopper is capable of storing 20 of each color, make the robot place 20 of each required color before asking you to refill. Then you refill all those colors, and it does another 20 of each required color. This would make it so you don't need to refill each time any one color runs out.

[@CreativeMindstorms]

That could indeed help! The problem is that you will probably sometimes end up having to place pixels in between other pixels, which is very prone to errors, as the new pixels will get stuck on the already placed pixels.
