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
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 !
