Rotating ring mechanism help !

Hello guys !

I have a question that I think belongs in this subreddit but not 100% sure.

I am trying to recreate the device in this video https://vimeo.com/74256380

|500x476

It is basically just a rotating ring with a polarizing filter mounted in the centre. I would presume that an Arduino and motors is being used here but I have no idea how it was executed.

If anyone here would be able to shed some light on how they think this is made on this I would really appreciate it !

Cheers,

Rory

Ok, tell us what you have tried and how well it worked.

Doubtful you would even need an arduino, just a DC motor with a reasonably constant speed.

Yes. It looks like the disc is sitting on the output shaft of a motor. Probably some sort of rubber sleeve over the shaft to create enough friction for the drive.

You could use the Arduino to vary the speed of the motor.
