Coil Gun / Grappling Hook.
I am kind of an amatuer prop designer and I've recently been taken with pocket sized coil guns. My question is quite simple: I would like to know what disposable camera (brand) contains an LED indicator that flashes/turns on when the capacitor is fully charged? I've seen one such disposable camera used in this post: https://www.instructables.com/id/The-Coil-Gum/
I would love to know the exact brand or alternatives.
I would really appreciate any and all help and would love to post the resulting product.
