If you have a hard drive, do not rush to throw it away. Even inoperative in these devices, you will surely find many usefulness for your homemade. This is a good engine, from which you can easily make a miniature grinder. And powerful neodymium magnets that can be used for various purposes.
Also in the “screw” there is one interesting electromagnet that controls the “writing head”, if we speak the ancient language So, if you apply electric current to this magnet, the head starts to move. One author decided to apply voltage to it, which goes to power the speakers, as a result, the head moves in unison with the music. If you show imagination, you can adapt a tambourine to it, well, or whatever you have enough imagination for ...
Materials and tools for homemade:
- old hard drive;
- a screwdriver with a set of bits ();
- two wires;
- soldering iron with solder;
- sound amplifier, powerful tape recorder, etc.
Homemade manufacturing process:
Step one. Disassemble the hard drive
The first thing you have to disassemble the hard drive. Sometimes unscrewing these screws, screwed into an aluminum case, is not so simple, so it will be convenient to use .. The most important thing is to remove the top cover, under which the hard drive itself is located. To do this, unscrew the screws. Sometimes there is another screw hidden under a paper seal, do not forget to unscrew it.
The author also removes the board, this is not necessary, because thanks to it, if you can start the engine.
Step Two Remove the head
Further, the author removes the head, this is done in order to connect power wires to it. We unscrew all the fixing screws and remove the head along with the cable. You will also need to remove the top half of the neodymium magnet. Further, the author amputates the native loop, and solders two wires to the head contacts. You can find the necessary contacts experimentally.
Step Three We collect and test
Now everything can be collected back. We fasten the head, it is usually located on the bearing and is held by one screw. We also install a neodymium magnet in place. Remove the wires so that they do not interfere with the head moving.
Now it remains to connect the wires to your sound amplifier and turn on the Mouzon properly
The head will immediately begin to move in accordance with the rhythm. Homemade is very simple, but in practice it turns out a funny sight. In principle, you can remove the head with a block of magnets and make some kind of funny little thing out of it.
