In the eternal struggle for office dominance, the motion-tracking Airsoft/Nerf/whatever, the autonomous turret seems to be the nuclear option. [Aaron] and [Davis] built a motion-tracking turret that uses openCV to detect movement, before hitting a relay to trigger the gun.
There’s a Raspberry Pi controlling a Logitech C210 Pi-compatible webcam, with a stepper hat for the Pi controlling two NEMA steppers that aim the gun. The design is simple but elegant, with a rotating base and an assembly that raises and lowers the weapon.
The openCV intrigues us. We want to see a openCV-powered turret with color detection, so your own team doesn’t get blasted along with your hapless enemies. Or if guarding your cubicle, how about a little openCV facial recognition?
If you want to take a stab at your own, [Aaron] and [Davis] show how they built their project in their Hackaday.io page and their Python script can be found on GitHub. Otherwise, check out the Counter Strike Airsoft robot, the Airsoft sentry gun, and the Nerf turret powered by Slack we published previously.

[matt8588] designed a smartgun rig for his Airsoft shotgun (YouTube, embedded below). He has a Rasperry Pi 3 mounted inside a PEQ box connected to an infrared camera with an IR tac light helping with illumination. A series of buttons control a crosshair pattern superimposed on the camera image, which is displayed on a tablet. You can also reposition the crosshairs to shoot further away. One of the buttons triggers a signal on the transmitter, for setting off Airsoft claymores during battle. A second Pi, a Zero, connects to an BerryIMU sensor that controls a “traffic light” arrangement of 12mm LEDs that warn him when he’s moving the gun too much to be accurate.
If you want to check out [Matt’s] progress, he’s posted videos of him showing off the gun’s accuracy, including one after the break in which he shoots accurately from a standing position while looking down at the tablet. You can find code for both Pi’s on his GitHub repository.
We suppose it goes without saying that Hackaday has a plethora of Airsoft projects. We especially love the Airsoft sentry gun, the rover-mounted Airsoft gun, and the drone-mounted POV Airsoft turret we published.

Ever since automated turrets became a thing in video games, people have strived to make their own — let’s be honest, who wouldn’t want an automated defense turret? Well, [Austiwawa] just finished making a pretty awesome Airsoft gun turret, and decided to make a video tutorial on how he made it.
The inspiration comes from Project Sentry Gun, a long-standing website dedicated to teaching people how to make automated sentry gun turrets. We’ve seen projects use this to turn Nerf guns into turrets, and people have even made their own paintball gun sentry turrets.
Following along the build only takes about 5 minutes of your time and summarizes the process very concisely. We particularly like the main rotation axis — one RC servo motor and 4 casters make up a controllable lazy susan that reduces the load on the servo motor and allows you to mount a pretty big gun on the turret.

[Jon] and his brother converted an RC car into a robot that can fire airsoft pellets into the air. The little motorized vehicle was disassembled and a handheld was attached to the top. A pulling mechanism was put in place and a safety procedure was added to make sure no accidents occurred.
The chassis stand was created to hold the handle. The setup was then tested at this point, and a Raspberry Pi server was configured to have a camera that would act as the eyes for the robot. Once everything was in place, the wheels hit the ground and the vehicle was able to move around, positioning itself to aim the servos at a designated target. Footage was transmitted via the web showing what the robot was looking at.
A video of the remote-controlled counter-strike robot can be seen after the break. You could consider this your toy army. That makes this one your toy air force.

To be honest, we’re surprised this hasn’t been tried before — then again, maybe it has! But what we do know is that the folks over at Flite Test have rigged up an electric Airsoft gun to a large RC airplane, aptly called The Kracken.
The planes are a scaled up version of their own FT Versa Wing, which feature two props, giving them the ability of differential thrust. Not only were they able to strap a semi-automatic Airsoft pistol on top, they also have two GoPros filming the action and giving the gunner a POV for shooting down the enemy plane! Don’t worry though, the enemy plane features its own weapon — A permanent marker! This hardly seems fair though, as the closer the marker gets, the easier shooting down the plane will be!
Don’t take our word for it though, check out the awesome video for yourself, after the break.

Taking the time to build a reactive target range really adds to the fun of toy weapons. It lets you move beyond just point and shoot to actual games of skill.
The project is anchored by an Arduino board. It connects to a piezo element on the back of each of these sheet metal targets. Detecting when a projectile hits the target works pretty much the exact same way the ever popular Knock-block works. To provide interactive enjoyment each target has an LED which, when lit, indicates that the target is active. From here it’s just a matter of coding to add different challenges. So far [Viktor Criterion] has implemented quick draw, timed, and rapid fire modes. The demo after the break shows off everything, including the slick modular design he came up with to make the system portable.
We’d love to see these targets mounted on motorized tracks. Each round would have the targets moving closer to you at a faster pace to keep you on your toes.

Yet another project that proves you need to acquire a laser cutter. This Airsoft turret rotates, tilts, and includes a hopper for ammo.
All of the pieces were cut from acrylic. The base includes a bracket which keeps the large rotating gear level by sandwiching it between the layers. That and the tilt mechanism are pretty straight forward. The module responsible for loading the BBs is pretty neat though. It uses a gear with round teeth the same diameter as the ammo. Once a BB is picked up it is forced upward into the tubing that feeds the gun. Get the full picture from the demo video after the break.
The one thing [The Liquider] is wondering about is how to provide feedback for the tilt and rotate functions. We can’t think of an easier way than to use simple rotary encoders. The Arduino Mega he wishes to use as a driver will have no problem interfacing with reflectance sensors and the acrylic makes it simple to mount this type of black and white encoder wheel.
