Spinning vinyl – an ipod app

by Theo Watson

Direct link here: http://vimeo.com/4353898

A quick app I put together this morning as a response to Todd Vanderlin’s AR scratching ( http://vimeo.com/4312616 ). The app uses the accelerometer of the ipod touch to control the speed of a ‘vinyl record’ on the ipod screen. Slowing down the record and speeding it up is just a matter of controlling how fast you spin the device.

Made with openFrameworks.

Next up scratching!
Track is Full Clip by Gang Starr.

Thanks to Zach Gage’s excellent ofxALSoundPlayer class!

Too sick. As soon as I jailbreak another phone i’ll see if i can bust out some beat juggles

Re: scratching: it could easily be accomplished by either the obvious method of spinning the disc (or record, or whatever) via the touchscreen.
OR
The more interesting way, the way you’ve done it. Directionality is pointless; just say the first time you spin it is “forward”, and any sudden changes means a change in direction.
(Of course, this depends on how fast you can poll the accelerometer.)

Can’t wait to play with it!

does somebody know where i can get this app?

gucio added these pithy words on Apr 28 09 at 8:36 am

it doesn’t exist yet (except on my ipod). I am working on getting it on the app store though – so stay tuned!

Could you put it up so if we jailbroke our ipods we could try it out?

Awesome. If you put it on a record player whilst its spinning, does it play at a normal speed?

It rocks, we need it on the App Store!

Looking forward to download and play it!

Is this application really real? On this video it looks kinda fake. Yeah… I know that it is possible to make this thing working. But specially on this footage, there is a strange movement and a fake light. Just impressions…

I agree with Ian… This is as fake as a 4 dollar bill… and the quality of sound is too good for a iphone speaker. :) kind regards, allsom.

From the conversation on Vimeo… determining which way an accelerometer is accelerating is a royal pain in the bloody arse. Tapping might work out nicely. Is there any way to use the camera to determine this? I look forward to seeing how you solve this one.

FAKE! The accelerometers are not capable of detecting this motion.

computer guy added these pithy words on May 01 09 at 7:11 pm

Actually, I take that back. The sensors can detect this. They could not detect rotational *position* but can detect rotational *motion*.. nice!

Grand emplacement et information utile, si vous avez plus sur cette mati�re me faisiez savoir

william ellis added these pithy words on May 06 09 at 5:31 am

@Computer guy, I believe he stated that he actually uses the outward force to detect how fast it’s spinning – centrifugal force increases with the speed of rotation.
So even if it couldn’t directly detect rotation it would word.

OMG. this is excellent to get your iphone/ipod scratched as you’ve never imagined…

David Esquivel added these pithy words on May 12 09 at 8:41 pm

Were can i download this??

ralph added these pithy words on Jun 21 09 at 10:05 am

This is a really cool app! You cant skratch on something that has no torque though…..

be23rk added these pithy words on Aug 05 09 at 7:42 pm

is this app available for download??

lintroller added these pithy words on Oct 12 09 at 1:05 pm

Doesn’t exist. Never has. But search “Vinyl” on the app store for a cool retro record player that actually does exist and does quite a bit. Plays all your itunes and looks groovy too.

JB added these pithy words on Oct 27 09 at 8:01 am

Hey theo im reallylooking forward to this app! Can u at least let us know when your going to put it on app store? Or even finish it? Thanks man i really appreciate it!!!

Emil added these pithy words on Jan 19 10 at 3:32 am

please submit it to appstore! plz

victor added these pithy words on Apr 10 10 at 5:37 pm

That’s one of the coolest things I’ve ever seen.

cafenitro added these pithy words on Sep 07 10 at 9:11 pm

Fun fun fun! We posted it in out blog as well. http://blog.remiix.net/?p=248
