iPod spinning vinyl

Here’s a quick demo that FAT’s [Theo Watson] put together. It uses the iPod’s accelerometer to measure how fast it’s spinning and plays the sound file accordingly. This only works on the iPod touch 2nd gen because of its curved case. He says scratching is coming next, but currently the app doesn’t know which direction it’s spinning since it’s measuring outward force. This project was done in response to [vanderlin]‘s AR scratching that used fiducials on records.

    Now if only you could hook up your iPhone wirelessly to a sound system, this could replace CD-playing DJs in the clubs!

    Won’t it literally scratch your iPhone/iPod Touch though?

    Sick!

    I WANT THIS SO BAD!!! where can i get it?

  5. @fujifan: Well it does have bluetooth sound. Could hook it up to a computer or a special adapter

    I just wonder what it will take for someone to create a holder for this thing so that it is motorized spinning. then you can grab the ipod and scratch with it when they add that function.

    That is fracking awsome!

    probably the neatest thing i have seen on hackaday in awhile

    How about choosing a more melodious song to show the effect. Playing a recorded scratching-session shows very little.

    Why not demo it with a stable tone? But a fun idea.

    Very cool. With constant rotation would the iPod still know that it is turning?

    Simply awesome.

    I completely agree w/ kender (it is fraking awesome)

    @alan parekh

    Yeah, I think it measures the centrifugal force. (or not :))

    Insane. Love it.

  15. Jrodimus says:

    Very nice. I wonder if the next step would be to have the record “auto rotate” and allow scratching that way. Or if you could link 2 together via bluetooth… Man, the possibilities are endless.

    “I was at a party listening to Brahms being played by the great Horowitz. Suddenly there was a click. The most horrible sound man ever invented, right in the middle of the music. Somebody rushed to change records. The mood was broken.”

    Finder, you are quite right. That is why they are having trouble adding the scratch effect. It measures the outward force on the ipod caused by spinning rather than the lateral force in the direction of spinning.

    Spin it right off the table and shatter on the floor.
