How awesome would it be to lie in bed and watch a movie on your iPad hanging overhead? It seemed really relaxed to me, so I went around looking for iPad holders that could provide this functionality. Unfortunately they don't come cheap, so I figured to build my own. The main requirement is that it can hold my iPad Air in it's Griffin Survivor case (total weight approx 800-900grams).

Materials used:
1 Tertial (Ikea swing arm desk lamp) ~10 euro's
1 iPad holder (cheap chinese one) ~10 euro's
4 extra springs (e.g. from another Tertial) (optional)
2 small screws
1 nail (optional)

Step 1: Disassemble the Tertial Lamp Socket

- Ensure that the lamp is not plugged in!
- Unscrew the lamp head from the arm
- Loosen the screw keeping the lamp wire fixed to the lamp head
- Remove the lamp socket. It is held to the lamp head with 2 plastic clamps. The best way to get it loose is to use your thumb to push the socket against the side of the lamp head, causing the clamp on the opposite to be slightly opened. Pry a small screwdriver in between to completely open the clamp. Pull out the socket, cause the other clamp to let loose.

Step 2: Disassemble the Wiring

- Ensure that the lamp is not plugged in!
- Remove the wires to the socket, they are clamped.
- Remove the wire altogether by pulling it through the swing arm.
- Don't throw the lamp head and wires away! You could use them to make a hang lamp.

Step 3: Attach IPad Holder

- Flatten the end of the arm
- Screw the iPad holder to the arm using some small screws. Be sure to attach it to the center of the iPad holder, else the iPad will not be balanced and will rotate.
Note that the iPad holder I have is adjustable in size and had a little lever for adjustment. The lever was unnecessary and in the way so I cut it away.

Step 4: Attach Springs

My iPad in its rock solid case is a little overweight, and too heavy for the arm. I tightened all the screws on the arm to provide more friction and I doubled up the springs on the upper part of the arm.

To 'adjust' the lower arm I bent a nail and use it as a pin to adjust the lower arm. I find that I don't often have to adjust the lower so it is not really inconvenient. I later replaced the nail by the springs I had left over from another Tertial.

Step 5: Pro-tip: Prevent the Arm From Falling Out of Its Base

The swing arm of the tertial stands loose in its base, and completely extending the arm with a heavy iPad could get the arm to fall out of the base. To prevent this from happening again I added a little screw into the arm. The arm already has a wide notch that seems to be made for this solution. The only drawback is that you can't swing the arm all the way around, but it is still more than 180 degrees.
