My wife and I recently went on a camping trip to the beach and I posted an instructable on how to ruggedize and bug-proof a small air conditioner here
. I knew we would be taking our iPad with us to check email and watch movies but I didn't want to have to hold or prop the iPad up the entire time not to mention I didn't want it lying in the bottom of the tent getting sand all over it so I decided to make a cheap, adjustable mount that would be sturdy enough to support the iPad but also easily transported. The best bang for your buck when it comes to piecing together a relatively sturdy structure for practically nothing is PVC of course. PVC pipe and connectors are basically tinkertoys for big kids!
