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.
