Picture of wristwatch turntables
Scratching records is loads of fun, even if you're not a turntablist. Don't you wish you could drop phat beats and scratch wherever you go? Well now you can; be a DJ Hero with wristwatch turntables!

Using 2 recordable greeting cards and some potentiometers you can record your own song, beat or sample, then playback and distort the sound to make your own music. These turntables are so small that you can strap to your wrist, making you the life of the party no matter where you go!

This project will cover the steps I took to make these specific sound turntables. New sounds can be recorded, and alternate greeting card styles(boards) can be substituted easily.
Feel free to remix and modify any of the circuit bending shown in this project to create your own unique turntables.

Mike - I saw this project posted on today and clicked over to instructables to see more about it. Great idea. can you mail one to the instructables office. I'd love to wear that when I travel for meetings with advertisers.

Ooohhh, this is nice!

With sufficient dexterity, you could probably scratch 'on-the-wrist'...

And what about a headphone socket, connecting to an amp, then some speakers (all portable - maybe a backpack?) so it's not just your mates who can hear you scracthin'?

I foresee endless possibilities (and more...)

Inspired perhaps by DJ Q-Bert's "Sneak Attack" video? I've often thought about a single wrist turntable but twin wheels of steel is awesomeness itself!
awesome, all though when I first clicked on it, i had thought you have built a "record player"into a watch - lol
