9g Servo Electric Screwdriver

UPDATE: We've added a new servo coupler and bit-holder system for added stability. It requires 2 608zz bearings. Check out the diagram for the exploded view to see how it fits together.

Here is a 5 volt, 9g servo driven, thumb joystick actuated, Arduino Nano controlled electric screwdriver. Wiring and assembly diagram in the works...

It works in both directions with variable speed control and is really intended for driving small bolts (M4 or smaller) rather than screws into materials like wood. It started out as an experiment to see if spare parts could be used to drive a small set of jeweler's screwdrivers laying around.

Don't throw out your real electric screwdrivers. This is just a fun project with lots of room for improvements.

This project requires friction welding. Tutorial here: https://appliedtechnologylab.blogspot.com/2018/06/3d-printing-tutorial-friction
