Hello. I've started recording my lectures with my iPad Mini, and am looking for a portable stand to keep it up, steady, on a desk while I write down notes. I've tried using a folding case but it's not stable and I can't adjust angles well to capture everything without it sliding up/down from the movement of writing. I just need something that will lift it off desk a few inches, and allow me to adjust the tilts, swivel as the lecturer goes across room, or uses raised projection screen. I'm also hoping for something cheap! Thanks for the suggestions!
