Launch mini paper airplanes from your desk, without ever winding up your arm. Perfect for office shenanigans or other indoor fun!
By using common electrical components we can make our own electric paper airplane launcher!
You might even discover you have many of the parts required already laying around, especially if you have any old toys with small DC motors.
Check out the launcher in action:
Pretty neat, right?Enough talk, let's launch some airplanes!
Step 1: Tools + materials
Step 2: Wiring diagram
The neat thing about these toy DC motors is that if you reverse the polarity they spin the other direction. Using this concept we can wire each motor up inversely to each other and create a opposing rotations, allowing a pinch-point to be formed by the rotors when placed next to each other. Then, by attaching rubber grommets to the rotor heads, we can use that pinch-point as a method to fling our paper airplane.
A switch was added to allow the motors to be user controlled.
Use care when wiring and don't short circuit your motors (like I did), or your batteries (which I also did).
