Bluetooth Water Cannon Junk Build Shoots Into Our Hearts

We’ve seen a few remote controlled turret builds in the past, but this one from [Noel Geren] is pretty neat: it shoots water and uses Bluetooth Low Energy (BLE) for control. Check it out in action in the video below.

[Noel] used the guts of a Nerf Thunderstrike water gun for the firing mechanism, combined with a 3D-printed enclosure and a servo that rotates the turret top. The pump from the gun is connected to a simple relay that replaces the trigger. Both the relay and the servo are connected to an RFDuino with a servo shield, which is programmed to respond to simple commands to rotate and fire.

It’s a nice junk build, and [Noel] has released all of the files for download if you want to build your own. It would make a nice weekend build or a project to do with the kids.

  1. I bought some electric misters for plants or reptiles at american science surplus for $2 a pop. But I can’t find them on aliexpress or alibaba…
    If we had those this project could be pretty BIG!
