Hello friends,

in this project, I made a rechargeable screwdriver with N20 geared dc motor. The motor has a 12V 60 RPM rotation speed. I used 3.7 volt 18650 lithium battery in the project. I increased the power of the battery to 9 volts with the voltage booster card. Normally, it can work with 12 volts, but I fixed it to 9 volts so that the voltage booster card does not overheat.

I hope it works for you too.

Enjoy watching.
