We will need:
- Old scanner;
- Rectifying diodes (8 1N4007 diodes were used in the project);
- Capacitor 1000 uF;
- LM7805;
- PVC pipe;
- Plastic parts (see below);
- Aluminum plates (any others can be used).
In addition to the plastic pipe and electronic components, we need a stepper motor, which is what we will need from the old scanner. The photo shows a four-phase stepper motor.

In addition to the plastic pipe and electronic components, we need a stepper motor, which is what we will need from the old scanner. The photo shows a four-phase stepper motor.
The stepper motor can be obtained not only from the scanner, but, for example, from an old magnetic disk drive.
Now that we have all the necessary components, we can begin assembling the rectifier. For each phase we need 2 diodes, i.e. only 8 diodes. The output voltage will be stabilized using a 1000uF capacitor and an LM7805 voltage regulator. This generator can freely produce more than 5 volts, but for this project, 5 volts was sufficient to charge mobile devices.
We collect the blades.
All !
Now you can try out the device, as can be seen in the photo - the device stably generates a voltage of 4.95 V. Now you can charge your MP3 player or phone for free!
If you liked the article about the wind generator, then I suggest you watch a couple of videos for reflection.
