If you’re a child of the 70s or 80s you probably recognize the Fisher Price record player in the above video. What you won’t recognize is the disk playing on it. While you likely listened to “Twinkle, Twinkle, Little Star” if you have access to a milling machine you can now create your own custom disks.
Instructables user ‘fred27′ does just that and has been kind enough to develop a full tutorial so you can do it too. He even built a custom app so you can put your favorite tune on a disk. Hipsters eat your heart out.
