A New Way to Spray Paint Color

What it is

It has been reported that a portable, Arduino-powered device can mix spray-paint colors on demand, letting artists dial up hues without lugging a whole closet of cans. The DIY rig, showcased by mechatronics engineer Sandesh Manik — who also runs a stealth startup focused on 3D modeling for hardware — promises on-the-fly color creation for spray-paint work. Neat trick: one gadget, many colors.

How it works

Think of it as a tiny color lab that lives in your hand. The system meters base pigments, blends them electronically, then atomizes the mixture into a spray can or nozzle. It’s Arduino-controlled and very much in the maker tradition: accessible components, a focus on hands-on tinkering, and a wink at customization — bring your own recipes, tweak as you go. James Provost’s photos show something compact enough to imagine carrying to a mural site.

Why it matters

Why should anyone care? For artists, it’s freedom — fewer crates of cans, more room for experimentation. For the planet, less waste and fewer half-empty cans heading to the trash. For the maker community, it’s another example of hardware that blends prototyping and practicality. Street artists and studio painters alike might feel a little giddy, or a lot relieved.

What’s next

Allegedly, this is still a hands-on project rather than a finished consumer product, so expect iterations. Will it go open source, spawn a startup, or remain a clever one-off? Time will tell. For now the idea lands squarely at the intersection of DIY culture and sustainable tools — and that’s a sweet spot the art world and tech world both keep an eye on.
