How Turntables work
A little while ago I posted an article about "How Speakers Work" within which I linked to a page on the Animagraphs.com website, which did a much better job of showing how speakers work then I ever could.
Now Mr O'Neal (the gentleman behind the website) has put together another one of his awesome graphics showing How Turntables Work, much like the speaker graphic this is a very simplified graphic but it covers all the important parts and gets in-depth enough to get everyone up to speed.
If you are interested in how it works, then have a look. If afterwards you have some questions, or would like some more information please feel free to get in contact.
