4 useful uses of the DVD drive mechanism

DVD and CD drives are gradually becoming obsolete, regardless of where they are installed: be it a computer or a DVD player. An era is passing, but a pile of iron remains idle. Now you will be presented with 4 useful homemade products that can be made from an old mechanism from such a drive.

DVD drive conversion


We remove the mechanism from the case. It should look something like this:

We unscrew the slide along which the laser head with shiny rods moves. Unscrew the motor that drives the disk. We leave only the engine with gears, which extends and retracts the slide.
Take a rectangular piece of aluminum or other metal. We drill 3 holes in it. We screw a self-tapping screw into one and put on an axle, which is made from paste from a gel pen. This will be the handle for rotation.

We screw short screws into the other two holes and put on plastic scraps.

We screw them into the gear.

The result is a kind of transmission, a gearbox of two gears, which increases the speed of rotation of the motor shaft by manual effort.

1. Flashlight generator.


If you connect to the output of an electric motor Light-emitting diode (or several of them), you will get a flashlight.

The gearbox allows you to rotate the handle slowly, and Light-emitting diode will shine very brightly.

2. Mobile battery charger.


You can connect a small 3 V battery to the output. And by rotating it, charge it and bring it back to life.

3. Hand generator for mobile phone.


If you connect a plug from a mobile phone to the output of the motor, you can get a manual generator for charging your mobile phone.

The advantage of such a device is that it is always ready to work in any conditions.

4. Device for transmitting mechanical rotation.


Electricity can be used to transmit mechanical torque.

We connect another motor to the output and it starts to spin when the generator handle is rotated.

Moreover, if you change the rotation, then the other motor also changes the direction of rotation.
These are the useful things you can make from old cider. Do you have any ideas about this? Write in the comments, everyone will definitely be interested.

    How does the phone behave if you turn the handle in the opposite direction?

      so you need to install an additional diode bridge then it won’t make a difference where to turn it

    This is all cool, but I wouldn’t do all this, there’s no point. Perhaps only on a desert island.
    Regarding charging - if you don’t mind your mobile phone, you can indulge yourself. But be prepared for the fact that he may die.

    Thank you, thanks to posts like this you can attract those who are curious about engineering)

    How long do you have to turn it to charge your mobile?

    I laughed for a long time while reading this article. I liked the comment about what will happen to the phone if you turn the knob in the other direction :) This is a very correct question, especially since the article does not say that this is important. I also do not recommend charging batteries - they are not designed for this. In your case, there will be nothing terrible - the battery is too small. In general, the article is really useful only for people who find themselves on a desert island; in normal life, you can find a more worthy use for this drive, for example, a CNC with a laser head for wood burning.

      The case when a comment is more informative than the article itself))))

      CR2032 is not a battery, but a lithium battery - you can charge it... how correctly? - another question. And polarity reversal is also destructive here

        Not everything that is a lithium battery is just a battery

        This is a battery with a very small capacity.

    and what does the drive have to do with it?

    Cool, let's go disassemble the drive! Otherwise there is nothing to charge the mobile phone with.

    Thanks for the tip! And for a long time I thought about what to use to make a controlled air duct damper for my home. Install a smart home... Branded ones are very expensive...
