Today it is common to have at home old CD players or DVDs that we no longer use and are a great hardware source for our DIY projects.
I am going to disassemble a CD player to see the pieces that we can take advantage of and I leave a list of very interesting projects (instructables) that can be done with each of the pieces. The links are projects in English, but little by little I will try to reproduce them and leave all the documentation in Spanish.
This model is quite old. I think it still works, but since I have 3 or 4 more it has been sacrificed for the article :)
Disassemble, recycle and reuse a CD / DVD reader
Before you go crazy everything comes out without forcing, so if any part you can't remove it is because you haven't removed all the screws and / or tabs. Don't make the sheep by tearing off pieces.
We began to open it carefully. It does not make much sense to give you the instructions on how to open it, since each model is made in a different way. This one came with 3 small tabs, which once moved, allowed one of the aluminum covers to move.
And time is a matter of calmly remove pieces until we get to the interior area that is the interesting one.
Don't throw away the screws, don't throw anything away. Save that we can reuse everything ;-)
Here we already appreciate the laser and the brushless motor in charge of spinning the CD. We continue removing screws from the sides, to be able to access the pieces well. As soon as we can, we will also separate it from the electronic board.
Nothing to review. We are going to keep the plate for now, I have not left any link to reuse it. At the moment it only occurs to me to remove components to reuse them, although all those that are SMD then are very difficult to take advantage of. I like the fat little legs of a lifetime.
Disassemble that disassembles you and we already remove the interesting part of the reader, I detail the image a little more
- CD extraction mechanismLook down to the right is a little motor that we will now see from the back.
- Brushless motor.
- CD laser
- Laser positioning system motor (The tutorial has left us here, because I was expecting a step by step with the screw attached)
If we see this from the back
We have a new part, 5 which is the motor that makes the CD player opening system work, 6,7 and 8 are the brushless, laser and the motor from behind.
Well, in case you want it clearer
We can continue dismantling. Because this is a non-stop, even then we can tear apart the laser, the brushless and the entire positioning structure, but I'm not going to go so far and I'm going to leave the complete pieces, which is what we will need for the recommended projects
DIY projects with the parts of a recycled CD / DVD player
And now what you were waiting for, those DIY projects to do with reader parts. Well, some projects need additional pieces, it is not only with the reader, for example it is easy for you to need an Arduino board, or the 3 CD / DVD mechanism and if you are going to make a mini-3D printer, you will need an extruder of course.
With the mechanism
Ok, I have spent dismantling and we have the problem that there is no step by step, but see what you can do with these pieces and structure.
With Brushles motor
To operate a brushless, it is not enough to connect it to the voltage and, as with a normal DC motor, we will need some drivers to make it work properly.
It is also typical to make an anemometer. I leave the brushless to scratch and see a lot of interesting things about this type of motors.
With stepper motor
Well, as I said, I expected to find a stepper motor like the one you will see in the tutorials, with the endless screw attached, I hope you have more luck than me, hehe
- Arduino Mini Laser Paper Cutter
- Arduino mini pen plotter
- The MicroSlice | A tiny Arduino laser cutter
With the laser
Beware of the laser, eyes and skin, it can be very dangerous and cause irreparable damage. If you have any questions, do not do these projects.
And with this we end the reader. "I promise" to do the recommended projects step by step as is the custom in Ikkaro. Do you know any more that are interesting?
