N20 Motor mount for LËGO Technic

Ever wanted to motorize your Technic build, but the original motors were simply too big to fit? WIth this motor, you can easily (and cheaply!) put any model to life, while keeping it very small. Or, you can put them on a bigger build and add more moving parts without worrying about available space.

The assembled motor is 2x3x5 studs long, and the axle sticks 1 stud out.

 

To make the motor yourself you need the following:

• 9V N20 motor, 400rpm or less
• Power Functions extension cable
• a soldering iron

First, cut off one end of the extension cable and put it through the hole in the smaller part. Then, solder the two middle wires to the motor (optionally, you can connect the motor contacts together using a small capacitor to stabilize voltage), put the motor into the bigger part and put the axle onto the motor shaft. Finally, close the case making sure not to damage the wires.
