It’s summer! It’s hot and this will help you cooling down!

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:

  1. I think the stream may be too strong to be used as an actual flamethrower, do you think so? I think the stream must be more vaporized in order for a flame to propogate. That is just my opinion…I am not an engineer. 🙂
    Also, would it be possible to use compressed natural gas as a flame source? But I imagine that would require many changes to the basic structure including replacing the water pump with some sort of valve and adding a pilot flame source to the nozzle.

  2. Hello, I have a question:

    How did you make the water pump, wheels, camera, and servo motors be controlled by the remote control? Please reply ASAP. Thanks!

  3. I used a standard 3channel RC receiver one channel for turning the servo, one servo for tilting, one channel connected to a motor driver which runs the pump! The camera is not connected to anything but its own receiver!

  4. I think this is awesome Iwas wondering if you if you could send me a parts list and instructions on how yo get it to work properly thank you for you creativity
