If you want the iPad to stay still standing up while recording in 720p HD, all you need to build this is KNEX pieces and an iPad for this stand.
Step 1: The Base
Step 2: Adding Rods to the Base
Step 3: Putting It Together
Step 4: You're Finished
Congrats!!! Now, just put your iPad in your finished stand. Be sure to look at the next pic to see that it's best to put the iPad in the thinner side of the stand. It's also best to have the lens that gets your face on the left in your view of the touch screen in the stand.
