- 2 x 4 (wood)
- 1/2 to 3/4 inch pine 2 1/2 inches wide
- 1/2 inch dowel
- Protractor and bevel guide
- Hand saw for wood
- Spokeshave or hand plane
- Belt or drum sander
Step 1: Grasp the 2 x 4 as shown
Step 2: Shape the wood block
When you are satisfied with the shape of the wood block, sand rough marks away with a belt or drum sander.
Step 3: Round for your thumb
Step 4: Drill a hole for the dowel
Step 5: Drill for the dowel
Step 6: Do not block the lens
Step 7: Round corners and dry fit
Step 8: Glue
This photo is from the underside of the camera holder, but it gives a view of how the compound angles work.
Step 9: Grasp the phone holder
This is designed to work comfortably when photographing objects on a table top. It can be used in other postures, but is not quite as comfortable. Now I can operate my phone's camera with one hand and not feel like the phone might slip out of my hand.
I did replace the rubber bands with pieces of aluminum. A wing nut allows removal and installation of the phone on the grip. See the 2nd photo. The text box indicates the screw on the other aluminum tab. My phone has a rubber "soft" case the aluminum tabs are able to grasp quite well.
UPDATE: I appreciate the comments by DarkTherapy. The earbud cable has a microphone on it with an up/down volume control button built into the microphone. Plug in the cable and press the up button to fire the camera shutter. This is a way of achieving a vibration free shutter release. He suggests making a pistol grip for the iPhone and placing the microphone portion of the earbud cable where it can be pressed easily. Dedicated shutter release cables for the iPhone are also available at this link and other places. (You would need to make certain part of the cable did not dangle in front of the camera lens and "ruin" the picture.)
