‘Ol Painless Paintball Mini-gun Packs a Mean Punch

Ol Painless Mini Gun

Remember Predator? Of course you do. This is [Corsae's] personal paintball gun rendition of one of the guns from it, ‘Ol Painless.

It’s a beautiful piece of work with countless man-hours going into its creation. At the core is an off-the-shelf EGO 08 paintball gun with a 20″ barrel. The barrel spacers are made out of MDF, cut by hand using a jigsaw with a barrel guide. The guide itself was made on a CNC router — too bad he couldn’t use it for everything! Each barrel is a thick-walled aluminum tube, carefully fit into the guides, and spray painted matte black for a clean finish. Sadly, they are only for aesthetics, as the paint balls shoot out through the central barrel only.

Not to worry though — while the paint balls may not come out of the barrels, the whole thing spins menacingly, which brings us to our favorite part of the project — the electronics. With help from his friend he designed a custom Arduino shield to control the motor, status LEDs and solenoid trigger. It’s fairly basic, but cool nonetheless. It features some wire connectors, diodes, an LED and the motor driver. Since the PCB fabrication cost included screen printing, he even threw on a mini-gun logo.

He’s done great job documenting the entire project in a photo gallery, with lots of notes along the way — stick around after the break to see a video of it shredding up the field.
