Here we have another way to take advantage of an old hard drive, doing with him a wheel for hamsters. The idea of this "technological" hamster wheel is to make it as quiet as possible so that the noise of the hamster running inside does not disturb us.
Si quieres buy silent hamster wheels at your pet store you will notice that they are quite expensive. With this hack, you will get your hamster to run at the speed of light without making any noise.
We will need a hard disk, from which we have to extract the motor shaft.
