Most of the maker stories we feature on this site usually involve an Arduino or Rasberry Pi and require coding and some degree of skill.

Sometimes we like to feature a simpler project that can be made with basic electronics, such as this “automatic” water pistol that works with a water pump.

This project comes to us from the good people at RobotGeek. “No coding, no microprocessor, just a pump, a battery, and a button” reads the description from their tutorial on hackster.io.

All you’ll need to make one of these advanced toy guns is those three items, some tubing and bolts, and a gun to fit it all into. While these kinds of builds would usually be crammed into an existing water pistol or another type of toy gun, RobotGeek instead made their own.

It’s a 3D printed solution whose files you can find on Thingiverse.

A nice feature of that 3D print is how the water reservoir is attached. Any bottle with a screw lid should fit into it. Many store-bought water pistols have adopted this technique, and it’s a nice way to choose the size of your “magazine” if you will.

This is the second time we’ve featured something from RobotGeek. The first was the Arduino-powered ShotBot that pours drinks for you when you can’t. We think this would pair perfectly with the Atari 2600 that was modified into a drinking game.
