Here is a picture of the unit unattached. Looking for more comments.

The unit runs on 12 volts. It has a programmable timer to make the film move. the roll of film is $16 and is 100' long. Only need to move film 3" to clear the view. that is 400 moves with one roll.

I build an item similar to this for racing helmet visors. I have made this prototype for CCTV to automatically clean the lens and wondering if there is a need for an item such as this? Looking for your commits, both good and bad.
