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 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.
