I spend a lot of time in my vehicles. Often while I am waiting in the car I like to use my IPad to browse the web, check email or read a book. I wanted to have a way to attach the IPad to the steering wheel because that seems like the logical place. I also wanted a design that would not tempt me to drive with the IPad on the wheel.
This design puts the IPad at a comfortable height for me but you could easily adjust the design to make it lower.
The two top dowels sit on top of the steering wheel. This holds it in place securely unless the wheel is turned. Always remove the IPad before you begin to move the vehicle.
I used 1/4" Baltic Birch Plywood for strength and stability. I plan to leave the cradle in the car and I'm sure that hardwood would warp over time.
You can cradle the IPad in either the portrait or landscape orientation.
