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.
I feel sorry for the housekeeping staff.. ;-)
Rubber bands on fishing line for auto reset.
Yeah, but what if they come in through the ceiling tiles?
Game over, man! Game over!
Electrify the ceiling, problem solved.
They mostly come at night… Mostly.
I can’t get a good look at the firing mechanism. It seems to have something to do with rotating the barrel. Does anyone have some idea what might be going on in there?
The string is underneath the rubber bands and as it is wound up then it pulls off a band.
Ah, I see it now. Very clever!
The guy in the next cube is taking my Astronaut Ice Cream packs? This calls for more than a rubber band turret!
LOL, nice trigger!
Servo needs to ease in ease and out… too jerky… and not scary :p
It’s a 3d printed project. If you can build it you have as many green pigs as you would like!
nice lol!!!
whoah, with this i can play rubber band war with my kids ! cool! my kids learn arduino fast with this course http://bit.ly/ArduinoCourse
