DIY Electric Screwdriver: Build a Mini Portable Driver

If you are interested in DIY electric screwdrivers, you might want to take a look at this article.

If you happen to already have an electric screwdriver, this electric screwdriver is relatively compact compared to a cordless drill, but it still feels quite bulky for digital products like smartphones. At this point, you may suddenly come up with the idea of making a mini electric driver.

If you happen to have an N20 small geared motor, with a working voltage of 3.7V and a speed of 72 RPM, and you also happen to have a 600mAh power battery, this battery is oval-shaped, which makes it convenient for wiring and fixing the circuit board. You also have a motor reversing board with charging function, as well as a 16mm wiring tube. Once all the materials are prepared, you can start making it.

The motor is slightly smaller than the tube, so you wrap tape around the motor so that it fits snugly into the tube, and then fix it with AB glue.

You cut a groove on the tube, and then place the battery and the circuit board inside in sequence. After that, you solder the wires properly.
