Intro: Cheap Motor-operated Screw Driver
A cheap motor operated cordless screw driver set.
- Geared motor 30RPM-60RPM
- Screw Driver set
- 9Volts Battery
- Soldering gun
- glue gun
- Pin to arrest the slip between motor and screwdriver
- 9V Battery terminals
Step 1: Rework on the Screw Driver
On the gripping side drill a hole to insert the motor shaft. I did not have a drilling machine therefore i used soldering gun to remove the material.
Insert the motor output shaft to the screwdriver hole and arrest the rotation using a pin
glue the battery to the motor and connect to the motor
i used bare terminals to reverse the polarity, you might want to use a DPDT switch to make it handy.
