Repurpose a Nintendo Zapper Into a Remote FPV Water Blaster
This robotic water gun is controlled with an FPV headset and RC transmitter.
It’s 2020, and water gun “combat” has stayed roughly the same for many years (besides the possible caveat that it should probably be done in smaller numbers). As seen here, however, Sean of Engineering After Hours decided to do things much differently, and made an FPV remote-controlled water soaker device based on RC hardware.
The build uses a pump and nozzle assembly to push water through a heavily-modified NES Zapper, which is held up by a ServoCity pan/tilt assembly. The newly-designed water gun can then be rotated up, down, left, and right, to track participants (willing or not) from afar, and soak them with water. An electronic pump squirts water out, and is powered by a 12V battery. This is switched by an actual servo, creating a sort of DIY relay setup.
The assembly is operated via an RC transmitter, while user feedback is accomplished using a drone style camera and FPV goggles. An IMU is hooked up to the headset for blaster face tracking, leaving only the on/off switch that has to be flipped on the actual RC unit for control. It’s a rather ingenious way to repurpose RC components, as there’s no additional microcontroller or programming involved.
Check out the video below for more inspiration, and one would note that many other items could be substituted for the Zapper here if you so prefer!
