Dot-Painting Graffiti Machine Is Wonderfully Simple

Traditionally, when many of us think of graffiti, we think of artists spraying away with simple paint cans. However, there’s often a lot of tech and art that goes into the field these days. [Vitaly Tesh] built himself a impressive dot-painting spray rig that’s really rather nifty.

The dot maker performed ably in this piece by [Vitaly].
The build starts with [Vitaly] using a heated Stanley knife to cut away a propeller assembly from a small toy drone. He then fits a small plastic disc to the motor in place of the prop.  The disc has a cutout so that as it spins, it only allows paint to pass at certain times. The whole package bolts onto a regular spray can, so it can be used with any paint color or brand that’s desired.

The spray can paints individual dots on the wall at varying distances apart, thanks to the spinning disc. Varying the speed of the motor or the rate at which the can is moved relative to the wall changes the pitch of the dots. Importantly, [Vitaly] included a drip capture system so that paint that doesn’t pass out of the dot aperture doesn’t leak all over his hands or the wall, ruining the piece.

We’ve seen robots put to work painting murals on walls, too. Video after the break.

      1. Nice argument, just one tiny issue: It is art if it is on your property. Everywhere else it is obnoxiously forced vandalism. Many trains where I live are covered in this “art” form.

        Since the location in the video looks abandoned, not much harm done, which is rare.

    1. A very limited few of them ARE tremendously talented. This particular guy… Personally my opinion is a resounding mêh. Generic, bland, same as I see all over the world in every alley, on every bridge. The sort of “art” that makes you scream: “Fuck off and find something useful to society to do”.

      1. Very, very limited few. Like one in one million or something like that. Pareto says 80% are just vandals with an can of paint. 80% of the rest lack any real talent. 80% of the remaining have some talent but lack skills… And so on.
        Curiously enough, the very talented ones are the most impacted by the vandals, because their effort tends to not live for long.

  1. This is actually really cool, as someone who’s planning on going into engineering, and as someone who enjoys spray painting. The only downside I could see is the waisted paint, if there was a way to minimize that, it would definitely be something I’d consider using myself!

  2. Idea is cool, artwork is pretty cool (cant read it so checks out as legit graffiti hehe, plus the dots pattern does look special) comments are so-so (we get it guys not everyone likes street art) but they have a fair point about waste.

    V2 suggestions: How about instead of spinning a disc in front of the nozzle you have the motor rotate a cam? pushing down on the cap/nozzle? i feel like that should get you the same effect without any waste/need to collect paint & requiring much less space? You can probably make that some self contained “secondary cap” with a dial (for speed) and a button (for painting) that you can easily clip to the top of any spray can? honestly seems like a marketable product ^^
