PIC controlled spray paint

Most people make LEDs light up for their first microcontroller project. [Alex] built a “large scale dot matrix printer.” This beast is a PIC controlled ground graffiti machine. As it rolls across the ground it deposits strategically located bits of spray paint. Rather than use actual spray paint, he opted for a set of solenoid controlled nozzles that shoot the paint downward.

    this looks like it could be the basis of an interesting business. “give us your images and we’ll paint them wherever you want them” and rig it up to go up and down a wall, on someone’s driveway, etc.

    Looks good, but some solenoids and straight spraying road marking paint cans would’ve made for a much less cumbersome rig.

    didn’t someone do this with spray chalk attached to a bicycle in new york and get arrested for it?

    Wolf, that would of made it alot easier but $33 per can…

    Yes someone did make a bicycle one that was remote controlled from his laptop…
