Here's the video about the whole project:


It all started with this little 6€ automobile water pump I bought on Amazon.

I attached the pump to an empty bottle and mounted both on a piece of wood. Then the whole Idea of a remote controlled water gun came up and I designed this out of aluminum parts:

As remote control I used an old 4 channel remote setup.

It uses two servos: one modded for continuous rotation (explained in another post) and the other not modded or changed at all. 

Aiming was pretty poor so I decided I needed some First-Person-Camera mounted on the water gun with live streaming to a display on the remote control.

This is a 2.4 Ghz wireless receiver for my wireless video cam.

It has a 12 Volt rechargable battery attached to it.

The screen I used is a simple rear-view car monitor which cost 20€ on Amazon.

After attaching both to the remote this is what it looks like:

Here's a little 3D view of the remote:

And here are some pictures of the masterpiece:

For aiming purposes I added a little laser diode aligned with the water pump:

And here's the demonstration footage:
