Custom Driver Board For Paintball Gun

custom-driver-circuit-for-paintball

[Gabe’s] been wanting to do some embedded development for years, and his other hobby of playing paintball recently provided him with a test project. He’s been working on a custom driver board for his paintball gun. ┬áDon’t be confused by the name, GCode is a mash-up of his name and the fact that he wrote the code for the project. It has nothing to do with the G Code CNC language.

At first this might seem like a trivial hack, but this Viking paintball gun has some serious velocity and throughput so he needs a reliable control that won’t just start shooting randomly. Another thing that [Gabe] took into consideration was monitoring the loading process to make sure the paintball is full seated before firing. All of this is handled by that tiny little Femtoduino board. it interfaces with the guns hardware using the connector board mounted above it.

There are several videos sprinkled throughout the build log. But we found the officially sanctioned 12.5 balls per second mode and the ridiculously fast auto-fire clips the most interesting. It should come in handy when on the run from paintball shotgun wielding opponents.

Autonomous Paintball Sentry Gun

What is the best thing about making a computer program that targets and kills anything that enters its sight? Why giving it a weapon, of course! No, we are not talking for real, but the next best thing, an Autonomous Paintball Sentry Gun.

The autonomous part of the device comes from a pc on the sideline and is fed input though a standard webcam. The feed is ran though a processing script where, once accustomed to the background has the option to fire at anything it sees moving, or a nice point n click manual mode.

The Arduino part is in a the role of driving the servo motors for X/Y movement and a trigger and is powered by a fist full of D cell batteries to give plenty of time for fun. Also, be sure to check out our other sentry guns, one using Microchip PIC, and another sporting a super compact computer running Ubuntu

Paintball Chronograph

This slick little chronograph can tell you how fast your paintballs are going, as well as what your firing rate is. In this instructible by [Klash69], you can see how to build one for yourself for less than $40. Chronographs themselves aren’t usually too interesting, but we thing he has done a great job here. You have a nice compact package with a big bright display. All it really needs now is a smooth enclosure. As far as the tech details go, he’s using IR sensors spaced 4 inches apart for detection, at the barrel. We’re not experts, but we think this might not work as well on a gun due to muzzle flash, someone who actually knows should let us know in the comments. The brains are a PIC18F13k50 and you can download a full parts list and schematic on the instructible.

You can see a video of it in use after the break.

Wearable Controller For Your Paintball Tank

If you’re too frail to take the full impact of a paintball round let this tank serve as your surrogate. The camera perched on top of the platform feeds video back to the operator’s head-mounted display. Instead of using a joystick or other traditional controller, the user aims by looking around, with his or her head movements mimicked by the camera and barrel of the tank. It looks cooler than it sounds so jump with us after the break to see for yourself. If you’re playing against this thing, we’d recommend aiming for the camera lens.

Paintball Graffitti

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.

Paintball Turret Plans Released

[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.

Automated Paintball Sentry

Reader, [Ben Godding], sends in the video for his senior design team’s automated paintball sentry. The frame is made of plasma cut aluminum. The paintball gun uses a custom hopper mounted remotely from the gun body. It has two webcams offering a 160 degree field of vision, and the image processing is done by a dual core pentium CPU booting windows xp off a compact flash card. The computer interfaces with the 1/4scale RC servos using a PIC24. The paintball sentry can either be configured via a computer GUI when a monitor is available or a baclkit keypad and 4×20 charachter display in the field.
