How to build a reel-to-reel tape device which handles photos? Answered

I want to make a physical interface for selecting a picture.

I will have a band of something which has little 1" plastic pockets on it.  Each pocket will contain a small photo of a person.

The band would be somehow attached to spools which would rotate via servos.

So the user presses a button to advance the spool one spot, and a new picture comes in the front.

I don't care if the pictures get a little bit bent, but they shouldn't get destroyed.

Let's assume the entire device is about 5" across, so two spools taking up an inch or so each, some space on the sides and one picture showing in the middle.

Just having two spools and a band which connects to itself is easy enough I think if it is the right length, but ideally, I'd like to store more images than can fit across 5" in the front and 5" in the back... so it would be something like an old tape machine. (i.e. the pictures wrap around a spool).

I have no idea how to accomplish this :)  I'm guessing the band would have to attach to the spool on each side... Any hints? Links? gotchas?

THanks!!

They had something quite similar in the old days, was called a movie projector.... ;)
Print your images on a suitable medium like vinyl and don't worry about pockets and cutting paper pictures.

Hey! Thanks for the response!

Yeah, that would make it easier, but I want them to be swappable. So you can add new faces / remove old ones (without printing on a new piece of vinyl.

I also had a 35mm camera / projector back in the day, but I was hoping for something simpler to build.
