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:
