friend of mine built this: https://www.instructables.com/HDDJ-Turning-an-old-hard-disk-drive-into-a-rotary/ https://www.instructables.com/HDDJ-Turning-an-old-hard-disk-... can't beat how smooth it is.

Love it! Very clever idea.

This looks awesome. I’m going to try building one this evening. It’s interesting reading the comments from 14-15 years ago, the capacity for hobbyists to do such things today is so much greater, even just since 2010.

that's interesting. the switch from vinyl to any of the other controllers was a very long time for me because I did not like the feel of any of the control surfaces at the time. the CDJ100s feel like fisher price toys which is probably what kept the prices a fraction of the CDJ1000s which had a much more acceptable feel. some of the digital only devices have gone back to that cheap light plastic feel with just a horrible bit of resistance. i often wonder how people tolerate it, but then i realize most people don't know what it was like playing vinyl and have nothing to compare to.

  I remember back in the day NI had a box that worked with traktor that came with some special vinyl records that had encoded signals built on it. You ran the output of the record players into the 'traktor box' and it would turn this into positional information for traktor .. seems like they still make the records: https://www.native-instruments.com/en/catalog/hardware/traktor/digital-vinyl/ https://www.native-instruments.com/en/catalog/hardware/trakt... I think the product, back in the day, might have been called traktor scratch.

I was just going to post about this! Not this particular project but the fact that most of us have old hard drives lying around that we could turn into rotary input device!

This is cool. I wonder how hard it would be to drive the motor just enough to compensate for friction so that it would spin forever at whatever speed you leave it instead of slowing down when you're not touching it.

I built one of those many years ago as well. :) * https://github.com/carlosefr/DisKnobUI * https://www.youtube.com/watch?v=MvpPVjJnbao It thought about using that (the spindle motor from a hard-disk) for this project. The issue is that it's not very precise at very low speeds. It sort of works, but it falls out of sequence too often.
