Electronics lovers and electronic homemade I’m sure to like this material, because in it we will consider a way to get a simple generator from an old CD / DVD drive of a computer.
The first thing we offer is to get acquainted with the author’s video
Consider what we need:
- old CD / DVD drive;
- nippers;
- soldering iron;
- any plastic case;
- wires;
- hexagon;
- the puck.
According to the author of a home-made generator, the idea is quite effective, since the ratio of the gear ratio of revolutions to the motor, which drives the gear that pulls out the disc tray, is quite large. Thus, it is possible that at low speeds of the same gear, good speeds will be obtained on the electric motor, and we will be able to get a generator. Whether it will be conceived or not, we will find out at the end of the review, and now let's get to work.
First, you need to unsolder the board on which the motor is mounted.
Next, cut off the part of the plastic drive housing on which the motor rests, as well as the gear we need. Later, from this gear, we will remove the handle so that it can be twisted and generate electricity.
We take the first wire and solder it to one of the contacts of the motor.
Solder the second wire to the second pin.
To test the generator, the author of the idea uses UBS inputs, which are installed in a plastic case. Therefore, he glues a piece of drive with a motor and gear into this case using a glue gun.
To make a pen you will need a hexagon and a washer. These parts need to be attached to each other. The author does this by soldering.
Solder the wires to the contacts of the USB connectors.
On the second half of the plastic case, you need to make a hole for the protrusion of the gear.
Finally, glue the homemade handle to the gear ledge. Our generator is ready.
In fact, such a generator can give a voltage of 3.5 - 4 volts, however, for this you need to rotate the gear quite quickly. However, such a generator will not work to charge a mobile phone, since it gives out unstable voltage.It is enough to light the LED, provided that the gear rotates stably.
