[Jared Bouck] is on a roll this week. We just covered his Diamond thermal paste and now he’s got more for us. To celebrate the re design of his website, he has released the plans for the paintball turret. As you may recall, we absolutely loved this design when he originally showed it to us. Though he has had kits available for a while, he has finally put the plans up for download. You can cut your own parts and build it yourself. He mentions that version 2 is coming shortly, we wait with bated breath.
[Jared Bouck] has been sending in his projects for a couple years now. We’ve enjoyed his heavy-duty DDR pads, LCD backlight repair, and ion cooling projects. His latest, an RC paintball gun turret, is our favorite though. He actually rates this as one of the easier projects he’s published; it just took a while to assemble. Several design decisions were made to keep the project simple. Two 32 Degrees Icon-E paintball guns were used. The guns already have electric solenoids for firing, so a special trigger mechanism didn’t have to be fashioned. Q-loaders were used to prevent any ball feed problems. The motors, driver boards, and RC components are all borrowed from combat robots for reliability. He’s hoping to produce a small number of kits based on this design.

You know that guy in the next cube is sneaking in when you are away and swiping packs of astronaut ice cream out of your desk. Thanks to [Kevin Thomas], if you have an Arduino and a 3D printer, you can build a rubber band sentry gun to protect your geeky comestibles. You’ll also need some metric hardware, an Arduino Uno, and a handful of servo motors.
The video shows [Kevin] manually aiming the gun, but the software can operate the gun autonomously, if you add some sensors to the hardware. The build details are a bit sparse, but there is a bill of material and that, combined with the 3D printing files and the videos, should allow you to figure it out.
We couldn’t help but wish for a first person view (FPV) camera and control via a cell phone, so you could snipe at those ice cream thieves while hiding in the broom closet. On the other hand, if you got the gun working, adding the remote wouldn’t be hard at all. You probably have a WiFi FPV camera on your quadcopter that finally came out of that tree and there’s lots of ways to do the controls via Bluetooth or WiFi.
Not that you don’t have options. But here at Hackaday HQ, we have lots of rubber bands and not so many green pigs. If you’d rather shoot paintballs, be careful you don’t accidentally repaint the insides of your cube.
It seems as though [Nathan] has taken some serious inspiration from the Warthog. The iconic armored buggy from Halo video games has a turret mounted to the roof. Although [Nathan]’s buggy only shoots paintballs from its turret.
Mounting paintball markers (guns) to various objects such as vehicles, robots, or other machines isn’t quite as straightforward as it seems. Vibrations from anything can transfer through a clamping system and cause paintballs to break. This, of course, inhibits the functionality of the marker and is a messy cleanup to boot. Then there has to be a way to fire the paintballs, which is usually handled by soldering to the electrical connections in the marker. And the entire rig has to stand up to the normal jostling and sudden turns from the buggy.
[Nathan] has solved these problems first by creating a custom fast-change mount that allows any malfunctioning markers to be changed rapidly. The electronic firing mechanism is handled by an ATtiny microcontroller and there is a custom electrical connection that is automatically made when the marker is bolted to the mount.
The new system allows markers to be changed in about 30 seconds, much better than any other system. Maybe in the future [Nathan] can upgrade the buggy’s turret to accommodate a paintball minigun.
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.
Paintball as a large format printer? That’s exactly what facade printer is. A paintball gun was mounted with two controllable axes of movement. A computer reads in the image data and prints it out by shooting paintballs to form a dot-matrix display. There’s a couple of wins here, the paintball paint can be washed off, and this will work on coarse or uneven display medium. Check out a video of the printing process after the break.
If you already built your own paintball turret, give the other guys and chance and hack it to print instead of gunning down unsuspecting adversaries.
